SUGGESTED ACTION
The Chanhassen Planning Commission recommends the City Council approve an amendment to
Interim Use Permit #2021-13 regarding Agritourism at 9111 Audubon Road to extend the
termination date to 50 years; and adopt the Findings of Fact and Recommendation."
SUMMARY
The applicant is requesting an amendment to the termination date for the interim use permit for the
Agritourism use of the property.
3
BACKGROUND
The applicant currently farms their property. The agritourism use began last September of 2021. They
would like to extend the termination date for the Agritourism use as part of their farming operation.
On August 9, 2021, the City Council approved:
The ordinance amending sections 1-2, 20-252, and 20-576 regarding Agritourism; and an Interim Use
Permit (IUP) for an Agritourism Use at 9111 Audubon Road with a termination date of five (5) years."
DISCUSSION
The IUP was originally approved for a period of five (5) years from the date of City Council approval.
This timeframe was intended to allow for the use to get established on the site and the City to evaluate
the impact of the use on the community. During the last half year of operation, the City has not received
any complaints. Even with the extension of the time frame for termination of the use, there are other
mechanisms to end the use due to violation of the conditions of the permit, changes in City zoning
regulations, or subdivision of the property.
RECOMMENDATION
Staff recommends that the Planning Commission recommend approval of the amendment for a fifty (50)
year termination date to the Interim Use Permit to permit the Agritourism use on the property, and
restates the other existing conditions; and adopt the Findings of Fact and Recommendation.

not the proposal meets the use standards outlined in the Zoning Ordinance. If the City finds that all
the applicable use standards are met, the permit must be approved. This is a quasi-judicial decision.
Notice of this public hearing has been mailed to all property owners within 500 feet.

The Chanhassen Planning Commission recommends City Council approve an amendment to
Interim Use Permit #2021-13 regarding Agritourism at 9111 Audubon Road to extend the
termination date to 50 years;
And
Adopts the Findings of Fact and Recommendation.”

Degler Farm IUP Amendment
March 1, 2022
Page 2
PROPOSAL/SUMMARY
The applicant is requesting an amendment to the termination date of the Interim Use Permit #2021-
13 to perpetuity. The Degler’s were concerned that the five-year termination date was a major
problem for their operation. They felt that the City could deny an extension of the Degler Farm IUP
without cause. An acceptable time would provide a longer term horizon for the recouping of
Agritourism attraction costs. Additionally, it would allow them to determine when the Agirtourism
ended at some interim time.
APPLICABLE REGULATIONS
Chapter 20, Article IV, Division 3, Standards for Agricultural and Residential Districts
Chapter 20, Article IV, Div. 5. Interim Use Permits
Chapter 20, Article X, Agricultural Estate District, A-2
BACKGROUND
The applicant currently farms their property. They would like to extend the termination date for the
Agritourism use as part of their farming operation.
On August 9, 2021, City Council approved:
The ordinance amending sections 1-2, 20-252, and 20-576 regarding Agritourism; and
An Interim Use Permit (IUP) for Agritourism Use at 9111 Audubon Road with a termination date of
five (5) years.
SITE CONSTRAINTS
Bluff Creek Corridor
This property is located within the Bluff Creek Overlay District (BCOD).
The City of Chanhassen established the Bluff Creek Overlay District (BCOD) by ordinance in 1998
to protect the Bluff Creek Corridor, wetlands, bluffs and significant stands of mature trees through
the use of careful site design and other low-impact practices. This parcel is partially encumbered by
the BCOD. Section 20-1255 of the Chanhassen City Code requires a conditional use permit for all
development within the Bluff Creek Corridor.
The Bluff Creek Corridor primary zone is located on the property. The Primary Corridor is
designated open space. All structures must meet a 40-foot structural setback from the Primary
Corridor boundary as required by Chanhassen City Code. In addition, no grading is allowed within
the first 20 feet of the Primary Corridor.
6
Degler Farm IUP Amendment
March 1, 2022
Page 3
The proposed development shall not impact the BCOD. No grading or vegetative alterations shall be
permitted in the BCOD Primary Zone.
Wetland Protection
There is a wetland located on the property. The proposed development should not impact this
wetland.
Bluff Protection
There are bluffs on the property. The proposed development should not impact the bluffs.
Shoreland Management
The property is located within a shoreland protection district.
Floodplain Overlay
This property is not within a floodplain.
SURROUNDING ZONING AND USES
The property to the west is in the city of Chaska. Two single-family homes are located to the west of
the site. The Preserve at Bluff Creek is located to the east across Bluff Creek. Liberty at Bluff
Creek is located to the south of the site. The Bluff Creek Primary Corridor wraps around the
southern and eastern portions of the property.
INTERIM USE PERMIT
The applicant is requesting an amendment to the termination date for the interim use permit for the
Agritourism use of the property.
City Code: Sec 20-323 Termination
An interim use permit shall terminate on the happening of any of the following events, whichever
first occurs:
1. The date stated in the permit;
2. Upon violation of conditions under which the permit was issued;
3. Upon change in the City's zoning regulations which renders the use nonconforming;
4. Upon the subdivision of the property or the alteration of the lot lines of the property.
State Statute: 394.303 INTERIM USES.
Subdivision 1.Definition.
An "interim use" is a temporary use of property until a particular date, until the occurrence of a
particular event, or until zoning regulations no longer permit it. The date or event that will terminate
the use can be identified with certainty.

Degler Farm IUP Amendment

Page 5
ACCESS
Access to the property is from Audubon Road (County Road 15). All conditions set forth by Carver
County shall be addressed by the applicant, and all permits required shall be obtained prior to the
commencement of and during operation of the Agritourism operations.
ANALYSIS
This area guided for office industrial uses with the Bluff Creek primary corridor guided for
permanent open space. As such continuation of the use in perpetuity is inconsistent with the City’s
Comprehensive Plan.
Interim Use Permits, pursuant to City Code and State Statute, require a termination date.
MISCELLANEOUS
The IUP was originally approved for a period of five (5) years from the date of City Council
approval. This timeframe was intended to allow for the use to get established on the site and the City
to evaluate the impact of the use on the community. Even with the extension of the time frame for
termination of the use, there are other mechanisms to end the use due to violation of the conditions
of the permit, changes in City zoning regulations, or subdivision of the property.
Any change in use of the current buildings on site, including the barn, will require it to come up to
building and fire codes. This will invoke MN Statute 1306, which will require the buildings to be
fitted with a Fire Suppression System and Fire Alarm System to monitor the Suppression System.
They would also need to address egress, exit and emergency lighting, door hardware, fire-rated
construction, and many other fire code-related items when it comes to change in use and access to
the general public. This includes bringing people through or any public access to a building, or the
construction or use of an observation tower. A tower will need to be built to current Building Code.
Safety concerns with the items on site such as: pumpkin canons, pumpkin catapult, zip lines, swings,
etc. Department of Labor and Industry is responsible for overseeing licensing for these items, which
are regulated by Minnesota Statutes Chapter 184B, Amusement Rides.
Corn/Straw Mazes – Any and all ignition sources will need to be a great distance away, including
open flame (recreational fire pits). Corn/straw mazes are highly combustible and can trap people
inside if a fire develops. Some research into history of corn maze fires states all vehicle parking and
any sources of ignition, such as campfires and smoking, be at least 75 feet away at all times.
Emergency Responder access – Will need to maintain emergency vehicle access to all areas on site
and entrance and egress. Will require proper road surface for emergency and fire vehicles. Possible
vehicle turnaround area depending on distances.
A fire hydrant will be required to be placed on site.

Sec 20-27 Revocation, Modification, Etc., Of Permits, Authorizations, Etc.
The city manager may issue an order to the owner or occupant of any premises to cease and desist
the use of such premises immediately, when such premises are being used in a manner creating
substantial hazard to the public health, safety or welfare, or in violation of any permit issued
pursuant hereto. The city manager shall have the power to prevent unlawful erection, construction,
reconstruction, alteration, repair, conversion, maintenance, or use of lands or structures within the
city and to restrain, correct or abate such violations, or to prevent the occupancy of buildings,
structures or lands, or prevent any illegal act, conduct, business, or use on or about said premises and
may use the city attorney, police and other personnel in accomplishing these duties.
Accessory agriculture buildings used for Agritourism Events must meet existing Building Code.
Existing buildings will more than likely change in occupancy type for this type of business, which
will require both the Fire Marshal and Building Official to confirm use, occupancy type, and
applicable codes for public use. A full architectural analysis would be required into items such as:
fire safety, egress, structural integrity, use and occupancy type, as well as many other applicable
codes. Special permission may not be given to leave existing buildings “as is” for use in
Agritourism.
One of the conditions of approval of the Interim Use Permit is an annual report of the activities
proposed for the upcoming year and an updated site plan with the parking location for the year shall
be submitted to the City by May 1st each year. As a follow-up to this report, site inspections shall be
performed prior to beginning the years activities.
PERMITS
Permits from the appropriate regulatory agencies must be obtained; including but not limited to the
Minnesota Department of Labor and Industry, Minnesota Agricultural Department, Minnesota
Pollution Control Agency, Riley Purgatory Bluff Creek Watershed District and Carver County.
UTILITIES
City utilities are available to the property. Water is located in Audubon Road. Sewer is located in
Lyman Boulevard and at the northeast corner of the property. However, none have been extended
into the interior of the site.
Sanitary facilities shall be provided for use of the visitors to the site. Such use shall comply with
Building Code or meet the requirements for chemical toilets spelled out in the Agritourism
Standards.
RECOMMENDATION
Staff recommends that the Planning Commission recommend approval of the amendment for a fifty
50) year termination date to the Interim Use Permit to permit the Agritourism use on the property
and restates the other existing conditions:

SUGGESTED ACTION
City Staff recommends the Planning Commission, acting as the Board of Appeals and Adjustments,
deny the requested opaque gate variance, deny the requested variance for a front yard parking pad,
and approve a 58-square foot water oriented accessory structure size variance, a 5-foot side yard
setback variance, and 2-foot shoreland setback variance for the construction of a water oriented
accessory structure, subject to the Conditions of Approval, and adopt the attached Findings of Facts
and Decision."
SUMMARY
The applicant is requesting a variance to construct a 6.5-foot high opaque gate within the required front
yard setback, a variance for a front yard parking pad, and variances from the water oriented accessory
structure (WOAS) maximum size limit, shoreland setback, and side yard setback to add a storage shed
to the property’s existing WOAS.
BACKGROUND
General History
In April of 1999, the City approved a two-lot subdivision with variances allowing for a 20% driveway
grade and 81-foot shoreland setback.*
Note: At the time this subdivision was proposed, the ordinance required structures maintain the
shoreland setbacks of the adjacent properties. This requirement was subsequently repealed and
properties are subjected to the current 75-foot shoreland setback.
In July of 1999, the City issued a building permit for the construction of a single-family home.
In March of 2000, the City issued a building permit to add a deck.
In November of 2018, the City issued a building permit for a significant remodel that included the
demolition of the existing deck and patio.
In June of 2020, the City issued a building permit to add a rooftop deck.
In April of 2021, the applicant applied for a building permit in compliance with Variance 2021-07.
Several permits for interior work and maintenance are also on file with the City.
Variance 2021-07 History
On May 21, 2020, the designer contacted staff with a proposal for the site that included a large concrete
patio off the rear of the home, a concrete patio and large WOAS near the lake, and a front yard parking
pad.
On May 22, 2020, staff expressed concerns about the likely presence of a bluff on the property and
25
provided the designer with the sections of the City Code that they believed would apply to the proposal.
Staff indicated that the proposal would require multiple variances and that a survey would be required
to determine the exact nature and extent of the variances.
On June 16, 2020, the designer sent a revised plan and requested a meeting with staff to discuss
potential variances.
On June 18, 2020, staff met with the applicant’s designer to discuss the proposed project. During the
meeting, staff expressed concern regarding the proposed size and placement of the WOAS, proposed
front yard parking pad, and presence of impervious surface within the bluff impact zone.
On July 16, 2020, staff and the designer met to discuss the proposed project. During the meeting, staff
expressed concern regarding the proposed size and placement of the WOAS, but was supportive of the
plans to stabilize the bluff and proposed pervious patio above the bluff.
On November 20, 2020, staff and the designer met to discuss the proposed project. The proposed
WOAS had been scaled back to address staff’s concerns.
On November 30, 2020, staff and the designer met to discuss the proposed project. No significant
concerns were raised.
On December 18, 2020, the applicant submitted the variance request.
On January 19, 2021, the Planning Commission approved a 19-foot bluff impact zone and 29-foot bluff
setback variance for the construction of a deck, a bluff impact zone and bluff setback variance for the
construction of retraining walls within the bluff, and a 25-foot bluff, 5-foot side yard, and 3-foot
shoreland setback for a WOAS.
On June 4, 2021, the applicant submitted a variance request to increase the width of the deck from 12 to
14 feet, replace the western concrete window well and retaining wall with a living wall system, and add
a 9-foot by 9-foot equipment pad and associated retaining wall to the east of the house.
On June 17, 2021, staff contacted the applicant expressing concern over the proposed equipment pad
and associated retaining wall’s encroachment into the bluff, and requested that the applicant investigate
the possibility of relocating or modifying the proposed equipment pad.
On June 22, 2021, the applicant agreed to remove the 9-foot by 9-foot pad and associated retaining wall,
revising the design to work within the existing boulder wall and AC pad’s encroachment into the bluff
setback.
On July 6, 2021, the Planning Commission approved a 20-foot bluff impact zone and 30-foot bluff
setback variance for the construction of a deck and a bluff impact zone and bluff setback variance for
the construction of retaining walls within the bluff.
On August 20, 2021, staff received a complaint that work on the site was exceeding what was permitted
by the variance. Staff conducted an inspection and found that no permit had been issued and that work
was being conducted by the lakeshore. A stop work order was issued. Subsequently, the applicant’s
contractor received a zoning permit for the deck and stairs and this portion of the stop work order was
lifted. He was informed that a grading permit would be needed to resume work on the slope.
26
From August 20, 2021 to September 16, 2021, staff and the applicant and their representatives had
multiple discussions centering on the scope of work being conducted on the property, what had been
approved as part of the variance, what ordinances and restrictions applied, and what permits were
needed.
On September 17, 2021, the applicant submitted a variance request asking the City to either revise their
determination that a bluff was present on the property or grant a series of variances from the provisions
of the bluff ordinance. The applicant also requested variances to add a shed to their existing WOAS and
install a 6.5-foot opaque privacy fence within the front yard setback.
On September 21, 2021, staff, after consulting with the City attorney, acknowledged that the property
was not subject to the bluff ordinance and provided the applicant with a list of the permits that would be
required for their proposed project. In this response, staff identified the proposed WOAS and front yard
privacy fence as items which would still require variances.
On September 27, 2021, the applicant updated their variance request to reflect the response they
received from staff on September 21, 2021.
On October 19, 2021, the applicant requested that their variance request be tabled at the October 19,
2021 Planning Commission meeting in order to allow them time to modify their request. They agreed to
waive the required 60-day review period and agreed to extend the deadline to March 31, 2022.
On February 28, 2022, the applicant submitted a revised variance request that reduced the proposed
extent of the proposed fence to an opaque gate and retained the proposed WOAS. They also included a
front yard parking area in their request.
DISCUSSION
The applicant is requesting that the City grant them a variance to install a 6.5-foot high opaque security
gate. The proposed gate would straddle the driveway and be setback approximately 10 feet from the
front property line. Since the City Code limits the height of opaque fences within the required 30-foot
front yard setback to three feet, a variance is required to permit the proposed opaque gate in this
location. The applicant is also requesting variances to allow them to add a 132-square foot shed to the
property’s existing 225.5-square foot WOAS, and a deck less than 30 inches in height. The resulting
structure would be 357.5 square feet in size with an 8-foot shoreland setback and a 1-foot side yard
setback. Since WOASs are limited to a maximum of 250 square feet and subject to 10-foot side and
shoreland setback, variances from these standards would be required to accommodate the proposed
structure’s size and placement. Finally, the applicant is requesting a variance to allow for a front yard
parking pad. Due to the City Code’s requirement that front yards remain unobstructed, save for certain
allowed encroachments, and limiting of residential properties to a single access within the right-of-way,
variances from these requirements would be required.
The applicant has stated that they are requesting a variance from the City’s prohibition on opaque
fencing within the front yard setback due to their concern that vehicles entering the driveway during
wet or icy conditions will be unable to stop and could crash into their home. They have noted that due to
the momentum that would be generated by a vehicle’s downward travel down their steep driveway a
gate placed 30 feet back from the front lot line would be much less likely to be able to stop an out of
control vehicle than one placed 10 feet back from the front lot line. They have also indicated that they
do not believe a three foot high opaque gate would be able to address their safety concerns.
27
Additionally, the applicant has stated that a front yard parking pad is necessary to provide a safe place
to park during inclement weather. They have noted that the pad would be located in the area occupied
by the property’s former driveway access and that it would not place the property over its permitted 25
percent lot cover limit.
Regarding the proposed WOAS, the applicant has stated that the shed is necessary due to the fact that
they do not have an area in which to store valuable equipment (patio furniture, boats, etc.) down by the
lake and that they have had previous issues with theft due to the inability to secure their property. They
observe that the site’s topography creates a difficulty in continuing hauling items from the home to the
lake and that a secure storage area is needed to remedy this. They have indicated the requested shed size
is the minimum needed to store their canoe and that it is unreasonable for the City to propose that a
portion of the recently built existing WOAS be removed due to the cost incurred in its constriction. The
have also noted that the proposed location would minimize the sheds visibility from the lake, as required
by code, and that there are provisions in the code allowing for a 400 square foot WOAS designed solely
for the storage of watercraft and related items. Finally, they note that the proposed shed would not
exceed the property’s lot cover limit and would be of a moveable design so as to not impede access to
the City’s sanitary sewer line.
In evaluating the requested variance for an opaque gate, staff cannot find that the applicant meets the
conditions required for granting the requested variance. The applicant has not demonstrated that their
security concern could not be addressed through a 6.5-foot high open gate, a 4-foot high chain link gate,
or a 3-foot high opaque gate located within the front yard setback, as permitted by City Code. Based on
the submitted material, the use of an opaque rather than open design for the gate appears to be a design
choice rather than an engineering necessity. Staff believes the City’ prohibition on tall opaque fences
and structures within the required front yard setback plays an important role in creating and maintaining
neighborhood aesthetics.
The existing parking pad that the applicant references is the old driveway access that was slated for
removal as part of the driveway realignment in previously submitted and approved plans. The City Code
does not permit front yard parking pads due to their increase of impervious surfaces within the right-of-
way, increased risk of accidents, and the maintenance issues they can create during snow emergencies,
as well as their aesthetic impact on neighborhoods. For these reasons staff cannot support the requested
variance.
Regarding the proposed WOAS, every riparian property in the city is subject to the same WOAS
restrictions and property owners often must choose between lakeshore storage and recreational
amenities. Staff believes that the WOAS regulations play an important role in limiting the amount of lot
cover, both pervious and impervious, installed along the lake and in preserving the shoreline’s
aesthetics. While the applicant is correct that the Code does allow for a 400-square foot WOAS, it does
not permit one in conjunction with other amenities, such as the existing deck, and it limits these
structures to a 20-foot width. The combined width of the applicant's deck and shed would be
approximately 31 feet. Additionally, staff notes that any shed over 200 square feet would need to meet
the requirements of the Building Code and the City would not allow the placement of this type of
structure in an easement occupied by active infrastructure. For these reasons, staff cannot support the
variance as requested; however, the property did have a nonconforming 308-square foot WOAS that
was located seven feet from the ordinary high water level (OHWL) and five feet from the side yard
setback. Under Variance 2021-07, the new deck was required to maintain those setbacks. While
replacing the pre-existing patio and deck with a shed would be considered an expansion of the
nonconformity, staff supports granting a variance to allow the applicant a 308-square foot WOAS with
an 8-foot shoreland setback and 5-foot side yard setback, consistent with the footprint of the pre-
28
existing WOAS.
A full discussion can be found in the attached staff report.
RECOMMENDATION
Staff recommends the Planning Commission, acting as the Board of Appeals and Adjustments, deny the
requested opaque gate variance, denies the requested variance for a front yard parking pad, and
approves a 58-square foot water oriented accessory structure size variance, a 5-foot side yard setback
variance, and 2-foot shoreland setback variance for the construction of a water oriented accessory
structure, subject to the Conditions of Approval, and adopt the attached Findings of Facts and Decision.
1. The applicant shall consult with City staff and apply for required permits, either building or
zoning, for all proposed structures (i.e. shed and deck).
2. No construction can occur until the required permits identified in Condition 1 are issued.
3. The applicant shall file for an Encroachment Agreement with the City for any encroachments
within public drainage and utility easements.
4. The shed and its appurtenances shall be constructed so that it is removable from the public utility
easement, for review and approval by the City prior to issuance of the required permit.
5. The applicant must apply for and receive any all applicable permits from the Riley Purgatory
Bluff Creek Water Shed District.

LEVEL OF CITY DISCRETION IN
DECISION-MAKING:
The City’s discretion in approving or denying a variance is limited to whether or not the
proposed project meets the standards in the Zoning Ordinance for a variance. The City has a
relatively high level of discretion with a variance because the applicant is seeking a deviation
from established standards. This is a quasi-judicial decision.
Notice of this public hearing has been mailed to all property owners within 500 feet.
PROPOSAL/SUMMARY:
The applicant is requesting that the City grant them a variance to install a 6.5-foot high opaque
security gate. The proposed gate would straddle the driveway and be setback approximately 10
feet from the front property line. Since the City Code limits the height of opaque fences within

opaque gate in this location. The applicant is also requesting variances to allow them to add a
132-square foot shed to the property’s existing 225.5-square foot WOAS, and a deck less than 30
inches in height. The resulting structure would be 357.5 square feet in size with an 8-foot
shoreland setback and a 1-foot side yard setback. Since WOASs are limited to a maximum of
250 square feet and subject to 10-foot side and shoreland setbacks, variances from these
standards would be required to accommodate the proposed structure’s size and placement.
Finally, the applicant is requesting a variance to allow for a front yard parking pad. Due to the
City Code’s requirement that front yards remain unobstructed, save for certain allowed
encroachments, and limiting of residential properties to a single access within the right-of-way,
variances from these requirements would be required.
The applicant has stated that they are requesting a variance from the City’s prohibition on
opaque fencing within the front yard setback due to their concern that vehicles entering the
driveway during wet or icy conditions will be unable to stop and could crash into their home.
They have noted that due to the momentum that would be generated by a vehicle’s downward
travel down their steep driveway a gate placed 30 feet back from the front lot line would be
much less likely to be able to stop an out of control vehicle than one placed 10 feet back from the

would be able to address their safety concerns.
Additionally, the applicant has stated that a front yard parking pad is necessary to provide a safe
place to park during inclement weather. They have noted that the pad would be located in the
area occupied by the property’s former driveway access and that it would not place the property
over its permitted 25 percent lot cover limit.

that their security concern could not be addressed through a 6.5-foot high open gate, a 4-foot

design for the gate appears to be a design choice rather than an engineering necessity. Staff
believes the City’s prohibition on tall opaque fences and structures within the required front yard
setback plays an important role in creating and maintaining neighborhood aesthetics.
The existing parking pad that the applicant references is the old driveway access that was slated
for removal as part of the driveway realignment in previously submitted and approved plans. The
City Code does not permit front yard parking pads due to their increase of impervious surfaces
within the right-of-way, increased risk of accidents, and the maintenance issues they can create
during snow emergencies, as well as their aesthetic impact on neighborhoods. For these reasons
staff cannot support the requested variance.
Regarding the proposed WOAS, every riparian property in the city is subject to the same WOAS
restrictions and property owners often must choose between lakeshore storage and recreational
amenities. Staff believes that the WOAS regulations play an important role in limiting the
amount of lot cover, both pervious and impervious, installed along the lake and in preserving the
shoreline’s aesthetics. While the applicant is correct that the Code does allow for a 400-square
foot WOAS, it does not permit one in conjunction with other amenities, such as the existing
deck, and it limits these structures to a 20-foot width. The combined width of the applicant’s
deck and shed would be approximately 31 feet. Additionally, staff notes that any shed over 200
square feet would need to meet the requirements of the Building Code and the City would not
allow the placement of this type of structure in an easement occupied by active infrastructure.
For these reasons, staff cannot support the variance as requested; however, the property did have
a nonconforming 308-square foot WOAS that was located seven feet from the ordinary high
water level (OHWL) and five feet from the side yard setback. Under variance 2021-07, the new
deck was required to maintain those setbacks. While replacing the pre-existing patio and deck
with a shed would be considered an expansion of the nonconformity, staff supports granting a
variance to allow the applicant a 308-square foot WOAS with an 8-foot shoreland setback and 5-
foot side yard setback, consistent with the footprint of the pre-existing WOAS.

Note: At the time this subdivision was proposed, the ordinance required structures maintain the
shoreland setbacks of the adjacent properties. This requirement was subsequently repealed and
properties are subjected to the current 75-foot shoreland setback.
In July of 1999, the City issued a building permit for the construction of a single-family home.
In March of 2000, the City issued a building permit to add a deck.
In November of 2018, the City issued a building permit for a significant remodel that include the
demolition of the existing deck and patio.
In June of 2020, the City issued a building permit to add a rooftop deck.
In April of 2021, the applicant applied for a building permit in compliance with Variance 2021-07.
Several permits for interior work and maintenance are also on file with the City.
Variance 2021-07 History
On May21, 2020, the designer contacted staff with a proposal for the site that included a large
concrete patio off the rear of the home, a concrete patio and large WOAS near the lake, and front
yard parking pad.
On May 22, 2020, staff expressed concerns about the likely presence of a bluff on the property and
provided the designer with the sections of the City Code that they believed would apply to the
proposal. Staff indicated that the proposal would require multiple variances and that a survey would
be required to determine the exact nature and extent of the variances.
On June 16, 2020, the designer sent a revised plan and requested a meeting with staff to discuss
potential variances.
On June 18, 2020, staff met with the applicant’s designer to discuss the proposed project. During the
meeting, staff expressed concern regarding the proposed size and placement of the WOAS,
proposed front yard parking, and presence of impervious surface within the bluff impact zone.
On July 16, 2020, staff and the designer met to discuss the proposed project. During the meeting,
staff expressed concern regarding the proposed size and placement of the WOAS but was
supportive of the plans to stabilize the bluff and proposed pervious patio above the bluff.
On November 20, 2020, staff and the designer met to discuss the proposed project. The proposed
WOAS had been scaled back to address staff’s concerns.
On November 30, 2020, staff and the designer met to discuss the proposed project. No significant
concerns were raised.

On December 18, 2020, the applicant submitted the variance request.
On January 19, 2021, the Planning Commission approved a 19-foot bluff impact zone and 29-foot
bluff setback variance for the construction of a deck, a bluff impact zone and bluff setback variance
for the construction of retraining walls within the bluff, and a 25-foot bluff, 5-foot side yard, and 3-
foot shoreland setback for a WOAS.
On June 4, 2021, the applicant submitted a variance request to increase the width of the deck from
12 to 14 feet, replace the western concrete window well and retaining wall with a living wall
system, and add a 9-foot by 9-foot equipment pad and associated retaining wall to the east of the
house.
On June 17, 2021, staff contacted the applicant expressing concern over the proposed equipment
pad and associated retaining wall’s encroachment into the bluff, and requested that the applicant
investigate the possibilityof relocating or modifying the proposed equipment pad.
On June 22, 2021, the applicant agreed to remove the 9-foot by 9-foot pad and associated retaining
wall, revising the design to work within the existing boulder wall and AC pad’s encroachment into
the bluff setback.
On July 6, 2021, the Planning Commission approved a 20-foot bluff impact zone and 30-foot bluff
setback variance for the construction of a deck and a bluff impact zone and bluff setback
variance for the construction of retaining walls within the bluff.
On August 20, 2021, staff received a complaint that work on the site was exceeding what was
permitted by the variance. Staff conducted an inspection and found that no permit had been
issued and that work was being conducted by the lakeshore. A stop work order was issued.
Subsequently, the applicant’s contractor received a zoning permit for the deck and stairs and this
portion of the stop work order was lifted. He was informed that a grading permit would be
needed to resume work on the slope.
From August 20, 2021 to September 16, 2021, staff and the applicant and their representatives
had multiple discussions centering on the scope of work being conducted on the property, what
had been approved as part of the variance, what ordinances and restrictions applied, and what
permits were needed.
On September 17, 2021, the applicant submitted a variance request asking the City to either
revise their determination that a bluff was present on the property or grant a series of variances
from the provisions of the bluff ordinance. The applicant also requested variances to add a shed
to their existing WOAS and install a 6.5-foot opaque privacy fence within the front yard and
shoreland setback.

Page 6
On September 21, 2021, staff, after consulting with the City attorney, acknowledged that the
property was not subject to the bluff ordinance and provided the applicant with a list of the
permits that would be required for their proposed project. In this response, staff identified the
proposed WOAS and front yard and shore land privacy fence as items which would still require
variances.
On September 27, 2021, the applicant updated their variance request to reflect the response they
received from staff on September 21, 2021.
On October 19, 2021, the applicant requested that their variance request be tabled at the
October 19, 2021 Planning Commission meeting in order to allow them time to modify their
request. They agreed to waive the required 60-day review period and agreed to extend the
deadline to March 31, 2022.
On February 28, 2022, the applicant submitted a revised variance request that reduced the
propose extent of the proposed fence to an opaque gate and retained the proposed WOAS. They
also included a front yard parking area in their request.
SITE CONSTRAINTS
Zoning Overview
The property is zoned Single-Family Residential District and is located within the Shoreland
Management District. This zoning classification requires riparian lots to be a minimum of 20,000
square feet, have front and rear yard setbacks of 30 feet, side yard setbacks of 10 feet, a
shoreland setback of 75 feet, and limits parcels to a maximum of 25 percent lot cover.
Residential structures are limited to 35 feet in height, and properties are allowed one WOAS up
to 250 square feet in size within the 75-foot shoreland setback. The shoreland ordinance allows
the construction of stairways, lifts, and landings, subject to design criteria. A portion of the
property is also encumbered by a sanitary sewer easement.
The lot is 27,878 square feet with 6,377 square feet (23 percent) lot cover. The home had a
preexisting WOAS which was a 308-square foot structure with a 5-foot side yard setback and 7-
foot shoreland setback. This WOAS was located within the City’s sanitary sewer easement. The
WOAS was replaced with a 225.5-square foot WOAS with a 5-foot side yard setback and 3-foot
shoreland setback. The house and other features appear to meet all other requirements of the City
Code.
Bluff Creek Corridor
The property is not encumbered by the Bluff Creek Overlay District.

There is not a bluff on the property.
Note: Based on the initial survey provided, staff determined that a bluff was present on the
property. The property owner subsequently demonstrated that the City’s definition of bluff
would not apply to the property and staff has acknowledged that the original bluff determination
was in error.
Floodplain Overlay
This property is not within a floodplain.
Shoreland Management
The property is located within a Shoreland Protection District. This District requires a 75-foot
structure setback from the lake’s OHWL and limits the property to a maximum impervious
surface coverage of 25 percent. The shoreland ordinance permits one WOAS to be located within
the 75-foot shoreland setback, provided that it is at least 10 feet from the OHWL, no larger than
250 square feet, and has a maximum height of 10 feet. Stairways, lifts and landings providing
access up and down bluffs and steep slopes to shore areas are also permitted so long as they do
not exceed four feet in width, do not cause soil erosion, and meet other design criteria. Fences
within the shoreland setback are limited to 3.5 feet in height.
Wetland Protection
There is not a wetland located in the development site.

March 1, 2022
Page 8
The plat for Pleasant View was recorded in
March of 1910 and Alicia Heights, a two-lot
subdivision within Pleasant View, was recorded
in June of 1999. Pleasant View is one of the
oldest neighborhoods in the city and it predates
the establishment of the City of Chanhassen and
its ordinances. The neighborhood is located on a
peninsula jutting into Lotus Lake and this
combined with challenging topography meaning
it has a large number of atypically shaped lots,
many of which do not conform to current City
standards. Some of the homes are original to the
neighborhood, while others are new construction
or have been extensively updated. Many
properties have nonconforming elements or have
received variances due to the age of the
neighborhood and atypical configuration of the
lots.

ANALYSIS
Opaque Gate
The applicant is requesting a variance for an
opaque gate setback approximately 10 feet
from the front property line. The applicant
is concerned that due to the driveway’s
steep 19.5 percent slope delivery trucks and
other vehicles entering the driveway during
wet or icy conditions may be unable to stop.
The applicant has noted that since
momentum increases with speed and
distance traveled, placing the gate near to
the property line will increase its ability to
stop out of control vehicles. They have also
stated that a 3-foot high opaque gate on the
downward slope would be unable to address
their security concerns.
In their narrative the applicant states that
their only alternative under the City Code is
an opaque fence of three feet or less in
height, which they do not believe will be
able to provide the required level of
security; however, the City Code also
allows for open fencing, defined as fencing
with no more than 20 percent opacity, to be
located within the required front yard
setback with a maximum height of 6.5 feet
and for chain link fences with a maximum height of four feet to be located in this area. While
the applicant is proposing placing an opaque gate 10 feet back from the property line, the City
Code would allow the placement of 3-foot opaque, 6.5-foot open, or 4-foot chain link fences
within the front yard setback. In order for the City to support the variance request, it would need
to be the case that none of the fencing permitted by the City Code could achieve the applicant’s
stated security goals.
38

for Variance
March 1, 2022
Page 10
While the applicant expresses concern over the
ability of a 3-foot opaque gate to stop a vehicle,
staff would note that SUVs tend to have ground
clearances of between 6-8 inches, with the
highest ground clearances being around 12
inches. Even for vehicles at the upper end of
this ground clearance, a three foot high barrier
would provide a significant obstacle in the
event of a low speed collision, such as would
happen with a vehicle sliding into the fence
immediately after decelerating for the turn into
the driveway. It is unlikely that a vehicle traveling at those speeds would flip over a 3-foot
barrier. To provide context, the Minnesota Department of Transportation requires roadway
guardrails to be between 28 inches and 31 inches in height, a height selected in part due to the
inability for most vehicles to surmount it.
The City Code would also permit the applicant to install a 6.5-foot open fence, i.e. a fence with
no more than 20 percent opacity, in the location where the applicant is proposing to install the
opaque fence. It is not clear that an open fence would be unable to provide an adequate stopping
mechanism. Staff would expect that the force needed to push open a gate’s automatic opening
mechanism, which by necessity is designed to open, would be less than the force required to
break a gate off of its hinges or break through the materials making up the gate itself. Staff does
not believe that a vehicle traveling at low speeds would have sufficient force to breach an open
construction steel gate, assuming the opening mechanism held. The applicant has not
demonstrated that an opaque style gate is necessary to withstand a low speed impact.
It should also be noted that variances should only be granted to the minimum extent necessary to
provide relief. The applicant is proposing a privacy style gate with nearly 100 percent opacity in
area that does not permit fencing of that height with over 20 percent opacity. If it could be
demonstrated that a gate meeting the City’s definition of open or meeting the City’s 3-foot height
restriction for opaque fences is structurally unable to provide adequate stopping power, the
minimum deviation from the 20 percent opacity or height standard necessary for the gate to serve
the proposed function would be the appropriate level of relief.
Finally, the City Code does allow the placement of opaque gates of up to 6.5 feet in height
behind the required 30-foot front yard setback. There are numerous gates on the market that are
rated to stop 15,000 pound vehicles traveling at speeds of 30 per hour which would be permitted
by City Code in that location. Staff understands that the applicant is not proposing installing a
K4 or M30 rated barrier and that the proposed placement 10 feet from the lot line is an attempt to
avoid the need for that robust of a structure as well as to limit the damage to any vehicle that
slides into the gate, but this further illustrates the presence of unexplored options within the
bounds of City Code.
39
6609 Horseshoe Curve Request
for Variance
March 1, 2022
Page 11
Staff sympathizes with the applicant’s concern and agrees that their desire to ensure their home
is not damaged by vehicle’s sliding down their driveway is reasonable; however, staff believes
there are options permitted by the City Code that would provide a similar level of protection as
the proposed opaque gate. In order to grant a variance, the City must find that “…the property
owner proposes to use the property in a reasonable manner not permitted by this chapter”, in this
case the reasonable manner of protecting the home from out of control vehicles is permitted by
the chapter. The use of a 6.5-foot high opaque gate in the proposed location rather than a gate
meeting the requirements of the ordinance is a design choice that is not necessitated by any
unique feature of the property. For this reason, staff cannot support the requested variance.
Front Yard Parking Pad
The applicant is proposing adding a parking pad located partially within the public right-of-way
and entirely within the front yard drainage and utility easement and front yard setback. The
applicant has indicated that they are currently using the property’s old driveway access as a front
yard parking area and that it is very helpful in inclement weather. They have indicated their
desire to place a permanent parking pad in that location and noted that it would not exceed the
property’s 25-percent lot cover limit.
Staff would note that when the applicant’s designer first approached staff with a conceptual plan
for improving the property, it included a proposed guest parking area within the right-of-way and
front yard setback and staff indicated that this would not be permitted by City Code in an email
dated May 22, 2020. All subsequent proposals did not include a front parking area and all
subsequently approved plans showed that the impervious surface and access associated with the
former driveway location would be removed. Permits were granted for the driveway realignment
because they showed that the existing driveway and its access would be removed.
The City allows residential property’s a single driveway access in order to limit the amount of
impervious surface within the public right of way and to provide for safe and efficient street
networks. Parking pads within the public right-of-way increase the risk of accidents, due to
vehicles colliding with parked vehicles or vehicles entering the street from unexpected locations.
Horseshoe Curve is a narrow public road and staff is concerned that allowing parked cars
abutting the road could intensify the risk of accidents. In addition to the potential safety
concerns, front yard parking pads can create street maintenance issues during snow emergencies.
Finally, the City prohibits front yard parking areas for aesthetic reasons as they result in the
replacement of lawns with large expanses of paved surfaces. The City Code also limits driveway
access to a maximum width of 24 feet at the right-of-way line, as part of its effort to limit the
amount of impervious surface within the right-of-way. The applicant’s proposal would create an
approximately 30-foot wide parking pad in addition to the 16-foot wide driveway, measured at
the property line. The combined width of these accesses would be nearly double what is
permitted by City Code and would result in 50 percent of the property’s street frontage being
impervious surface. Granting the requested variance would not be consistent with the
40
6609 Horseshoe Curve Request
for Variance
March 1, 2022
Page 12
ordinance’s intent of preserving front yard greenspace and limiting impervious surfaces within
the right-of-way.
Staff notes that while the neighboring property has a parking/turn around area associated with its
drive, it is separated from the roadway and appears to be located within its owner’s property.
This feature can be observed on aerials dating to 1997 and would be considered a nonconforming
driveway turnaround due to its location outside of the public right-of-way but within the
property’s drainage and utilities easement. It is the intent of the City Code to encourage the
elimination of nonconforming uses and the presence of a nonconformity within a neighborhood
should not be used as grounds to allow for the proliferation of deviations from the City Code.
For the aforementioned reasons, staff cannot support a variance request to locate a parking pad
within the public right-of-way and the applicant’s front yard.
Water-Oriented Accessory Structure (WOAS)
The applicant is requesting a 107.5-square foot
variance to allow them to add a 132-square foot
shed to the property’s existing 225.5-square
foot WOAS. The proposed placement of the
shed would put it within one foot of the side lot
line and eight feet from the OHWL. In the
graphic (shown at right), the footprint of the
pre-existing WOAS is shown in light purple,
the proposed revised placement of the deck
which was replaced is shown in black, and the
proposed shed is shown in light blue. The
applicant is requesting variances to permit the
construction of the shed due to the challenges
of transporting equipment down the steep slope
from the home to the lake and the need to
secure items that need to be stored by the lake,
and has stated that the proposed size is the
minimum necessary to allow them to store their canoe within the shed.
The City recognizes the need for lakeshore storage and recreational amenities, as well as the
importance of minimizing the number and size structures located along the shore. The City’s
WOAS ordinance strikes a balance between these two needs by permitting one structure of up to
250 square feet located 10 feet from the side yard and 10 feet from the OHWL. For the purpose
of applying the ordinance’s one structure provision, the City treats adjacent structures as a single
structure. Every riparian parcel in the city is subject to these standards, unless they benefit from a
legal nonconformity or variance, and though many owners would like additional storage space or
multiple structures, City staff has always taken the position that property owners must prioritize
how they configure their allowed WOAS. The Minnesota Department of Natural Resources
41
6609 Horseshoe Curve Request
for Variance
March 1, 2022
Page 13
responded to the City’s request for comment by noting that variances from the WOAS standards
should only be granted when there are rare and unique circumstances. The DNR has recommend
that the City not approve any deviation from the ordinance’s standards.
Historically, variances have only been supported by City staff when a pre-existing condition is
present. In this case, the applicant’s property did have a preexisting WOAS that was 308 square
feet in size, five feet from the side lot line, and seven feet from the OHWL. The presence of this
nonconforming structure was the rationale for staff formalizing the nonconforming setbacks as
part of Variance 2021-07 and permitting the installation of a movable structure over the City’s
sanitary sewer line, a situation that would not normally be permitted. While increasing the height
of a nonconforming structure, such as by adding a shed on top of an existing patio or deck,
would be an expansion of a nonconformity and require a variance, staff believes it would be
consistent with past practice to support granting a variance allowing the applicant a 308-square
foot structure setback five feet from the side lot line. The proposed increase from a 7-foot
OHWL setback to an 8-foot OWHL setback would be a reduction to the previous nonconformity.
The applicant could meet the 308-square foot requirement by either placing the proposed shed
partially over the existing deck or removing 49.5 square feet of the existing decking.
Alternatively, a smaller shed could be constructed. Any structure in the area would need to meet
the Engineering Department’s requirements for encroachment in the sanitary sewer easement.
The applicant has not demonstrated that there are any unique features to their lot which would
justify allowing an expansion of their WOAS beyond the size of the pre-existing structure or
which would require it to encroach closer than five feet to the side lot line. As the applicant has
noted, they initially chose to construct the deck instead of a storage structure within the
preexisting WOAS’s footprint and have now determined
that a shed is necessary. The applicant has stated that they
chose to construct the deck because they had been
informed by staff that they had to choose between a shed
or a deck. On July 8, 2020 staff sent the applicant’s
designer a written response to questions regarding the
City’s WOAS ordinance where staff stated “The City has
considered patios/decks attached to a shed/boat house to
constitute a single structure with an aggregate size limit of
250 sq. ft.” This was significantly in advance of the
November 20, 2020 redesign where the designer submitted
a plan showing a sub-250-square foot WOAS and the
initial December 18, 2020 variance submittal.
Additionally, staff’s initial May 22, 2020 response to a
WOAS inquiry for the property noted “These structures
are limited to a maximum of 250 square feet (including the building and any associated
patio/decking).” Given that accurate information was provided to the party responsible for the
design in writing in advance of revisions and the initial variance submittal, staff cannot agree
with the applicant’s statement that staff informed them they could have either a deck or a shed,
but not a structure incorporating both.
42
6609 Horseshoe Curve Request
for Variance
March 1, 2022
Page 14
The applicant notes that the City Code allows for an up to 400-square foot shed to be placed on
properties solely for the storage of boats and boating-related equipment. While this is correct,
that is not the use the applicant is proposing. The applicant is proposing a combined deck and
shed WOAS which is not entitled to those dimensions. Additionally, the 400-square foot
boathouses are limited to a maximum width of 20 feet, while the applicant is proposing an
approximately 31-foot wide structure. Finally, while the WOAS does allow for 400-square foot
structures, these structures would require a building permit and Engineering would not support
placing a structure meeting the requirements of the State Building Code over an active sanitary
sewer easement.
It should be noted that the Engineering department has expressed concerns in their memo about
the desirability of approving any variance accommodating the placement of a shed overtop the
sanitary sewer. They have stated that they feel the proposed structure and location should be
considered an encumbrance that would alter the intended use of the easement, and as such they
are recommending that the WOAS variance be denied in its entirety.
The constraints created by the presence of the deck do not justify the requested variances. For
these reasons, staff is recommending that only a variance commensurate with the pre-existing
nonconforming structures size and encroachment be approved.
Impact on Neighborhood
Pleasant View is an older neighborhood with many atypically shaped lots, nonconformities, and
variances; however, to staff’s knowledge, no property in the neighborhood has 6.5-foot opaque
gate within the front yard. Fences and gates have a large visual impact. Granting the requested
fence variance would negatively impact the neighborhood’s aesthetics, especially if other
residents requested and were granted similar variances. Similarly, front yard parking pads are
highly visible encroachments into required front yards and the public right-of-way. Many
properties with downward sloping driveways or narrow driveways may wish to have an
additional parking area. The proliferation of these types of structures would negatively impact
the character of the neighborhood. Finally, due to their shoreland location, WOASs are highly
visible. Properties with larger or more numerous structures than others are noticed and cited by
residents interested in increasing the size of or adding an additional WOAS to their own
properties. The aesthetic and environmental benefits that come from limiting the size and number
of WOASs can only be realized if the City universally applies these standards.
RECOMMENDATION
Staff recommends the Planning Commission, acting as the Board of Appeals and Adjustments,
deny the requested opaque gate variance, denies the requested variance for a front yard parking
pad, and approves a 58-square foot water oriented accessory structure size variance, a 5-foot side
yard setback variance, and 2-foot shoreland setback variance for the construction of a water

On March 1, 2022, the Chanhassen Planning Commission, acting as the Board of Appeals and
Adjustments, met at its regularly scheduled meeting to consider the application. The Planning
Commission conducted a public hearing on the proposed variances preceded by published and mailed
notice. The Board of Appeals and Adjustments makes the following:
FINDINGS OF FACT
1. The property is currently zoned Single-Family Residential District (RSF).
2. The property is guided in the Chanhassen Comprehensive Plan for Residential Low Density.
3. The legal description of the property is:
Lots 1, Block 1, Alicia Heights
4. Variance Findings – Section 20-58 of the City Code provides the following criteria for the granting
of a variance:
a. Variances shall only be permitted when they are in harmony with the general purposes and intent
of this Chapter and when the variances are consistent with the Comprehensive Plan.
Finding:The intent of the City Code’s prohibition on tall opaque front yard fences is to create an
attractive and consistent neighborhood aesthetic. The City Code allows for the use of open fences
of up to 6.5 feet in hieght, chain link fences of up to four feet in height, and opaque fences of up
to three feet in height to address security concerns. Granting the requested variances from the
City’s fence height standards would not be consistent with the general purposes and intent of the
City’s Zoning Code.
The City Code prohibits the placement of parking pads within the required front yard to limit the
amount of impervious surface in the right-of-way, provide an attractive and consistent
neighborhood aesthetic, and to provide for safe and efficient street networks. Granting the
requested variances to permit a front yard parking pad would not be consistent with the general
purposes and intent of the City’s Zoning Code.
It is the intent of the City Code to limit the size and location of structures within the required
shoreland setback and to balance recognizing the rights of nonconforming structures to continue
to exist with preventing their expansion. It would not be in line with the intent of the Zoning
45
2
Code to permit the applicant to construct a WOAS larger than the nonconforming WOAS that
was previously present on the site. It would be consistent with the intention of the nonconforming
use ordinance to grant a variance allowing the applicant to replace a portion of the
nonconforming WOAS with a shed, increasing the height of the nonconformity in exchange for
increasing the shoreland setback, so long as the size and side yard setback of the nonconforming
WOAS are not increased.
b.When there are practical difficulties in complying with the zoning ordinance. "Practical
difficulties" as used in connection with the granting of a variance, means that the property owner
proposes to use the property in a reasonable manner not permitted by this Chapter. Practical
difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy
systems.
Finding:The applicant has not demonstrated that they cannot achieve their goals of increasing
their property’s security within the bounds of the City’s Code of Ordinances without the need for
a variance.
The applicant has not demonstrated why the right-of-way access and driveway configurations
permitted by the City Code do not provide reasonable parking options.
The applicant’s desire for a WOAS to store equipment is permitted by the City’s Code of
Ordinances; however, the requested size and position is not. The applicant has the ability to
reconfigure the proposed WOAS to maintain the size and encroachments of the nonconforming
WOAS that was previously present on the site.
c. That the purpose of the variation is not based upon economic considerations alone.
Finding: The variance request is not solely based upon economic considerations.
d. The plight of the landowner is due to circumstances unique to the property not created by the
landowner.
Finding:The stated front yard security concerns can be addressed through mechanisms other
than the proposed gate. The proposed opaque design for the gate appears to be a design choice
rather than a requirement for the gate to serve its intended function.
While the driveway grade is steep, the property was adequately served by the pervious driveway
without a separate front yard parking pad for over twenty years.
The applicant’s requested variances from the City’s WOAS standards are the result of their
previous decision to replace the previous WOAS with an at-grade deck rather than a storage shed
and their subsequent realization that storage space was necessary. No unique features are present
that would prevent the applicant from constructing a WOAS that maintains the size and
encroachments of the nonconforming WOAS that was previously present on the site.
e. The variance, if granted, will not alter the essential character of the locality.
Finding: Pleasant View is an older neighborhood with many atypically shaped lots,
nonconformities, and variances; however, to staff’s knowledge no property in the neighborhood
has a 6.5-foot opaque gate within the front yard. Fences and gates have a large visual impact.
46
3
Granting the requested fence variance would negatively impact the neighborhood’s aesthetics,
especially if other residents requested and were granted similar variances. Similarly, front yard
parking pads are highly visible encroachments into required front yards and the public right-of-
way. Many properties with downward sloping driveways or narrow driveways may wish to have
an additional parking area. The proliferation of these types of structures would negatively impact
the character of the neighborhood. Finally, due to their shoreland location, WOASs are highly
visible. Properties with larger or more numerous structures than others are noticed and cited by
residents interested in increasing the size of or adding an additional WOAS to their own
properties. The aesthetic and environmental benefits that come from limiting the size and number
of WOASs can only be realized if the City universally applies these standards.
f. Variances shall be granted for earth-sheltered construction as defined in Minnesota Statutes
Section 216C.06, subdivision 14, when in harmony with this Chapter.
Finding: This does not apply to this request.
5. The planning report #2021-07B, dated March 1, 2022, prepared by MacKenzie Young-Walters, is
incorporated herein.
DECISION
The Chanhassen Board of Appeals and Adjustments, denies the requested opaque gate variance,
denies the requested variance for a front yard parking pad, and approves a 58-square foot water oriented
accessory structure (WOAS) size variance, a 5-foot side yard setback variance, and 2-foot shoreland
setback variance for the construction of a water oriented accessory structure, subject to the Conditions of
Approval, and adopt the attached Findings of Facts and Decision.
1. The applicant shall consult with City staff and apply for required permits, either building or
zoning, for all proposed structures (i.e. shed and deck).
2. No construction can occur until the required permits identified in Condition 1 are issued.
3. The applicant shall file for an Encroachment Agreement with the City for any encroachments
within public drainage and utility easements.
4. The shed and its appurtenances shall be constructed so that it is removable from the public utility
easement, for review and approval by the City prior to issuance of the required permit.
5. The applicant must apply for and receive any all applicable permits from the Riley Purgatory
Bluff Creek Water Shed District.
ADOPTED by the Chanhassen Planning Commission this 1st day of March, 2022.

Re: Fence, Parking Pad and Shed Variance at 6609 Horseshoe Curve –
Planning Case #2021-07B
The Engineering Department has reviewed the Variance submittal for 6609 Horseshoe Curve.
These comments are divided into two categories: general comments and proposed conditions.
General comments are informational points to guide the applicant in the proper planning of
public works infrastructure for this project, to inform the applicant of possible extraordinary
issues and/or to provide the basis for findings. Proposed conditions are requirements that
Engineering recommends be formally imposed on the applicant in the final order. Note that
references to the “City Standards” herein refer to the City of Chanhassen Standard
Specifications and Detail Plates.
General Comments/Findings
1. Any and all grading, utility and transportation plans submitted with this application have
been reviewed only for the purpose of determining the feasibility of the plans and
providing utility and transportation facilities for the project in accordance with City
Standards. A recommendation of variance approval does not constitute final approval
of details, including but not limited to alignments, materials and points of access,
connection or discharge, that are depicted or suggested in the application. The
119
applicant is required to submit detailed construction drawings and/or plat drawings for
the project, as applicable. The City of Chanhassen Engineering and Public Works
Department will review plans, in detail, when they are submitted and approve, reject or
require modifications to the plans or drawings based upon conformance with City
Standards, the Chanhassen Code of Ordinances and the professional engineering
judgment of the City Engineer.
2. It is the opinion of the Engineering Department that the proposed variance requests
cannot be developed in accordance with the requirements of the Chanhassen Code of
Ordinances (as it pertains to Engineering and Public Works requirements) and City
Standards.
3. The applicant previously proposed the reconfiguration and realignment of an existing
Water Oriented Structure (WOAS) which was approved in 2021. The existing WOAS
consisted of stone pavers and wood decking which was removed and replaced with
modular wood decking along with a smaller footprint than the previous non-conforming
WOAS. The WOAS lies within a public drainage and utility easement (DUE) that was
recorded with the Alicia Heights plat in 1999. Addit ionally, the city owns and maintains
a public sanitary sewer main constructed in 1975 that is located within the DUE and
located directly under the existing and previously approved WOAS. As such, the
applicant was required to enter into an encroachment agreement for the approved
WOAS, and the WOAS was constructed so that the decking was removable to allow for
access to and for the proper maintenance of the public sanitary sewer main located
directly underneath. The applicant is now proposing the addition of a shed to be
attached to the modular wood deck. The addition of the shed to the modular wood deck
increases the WOAS square footage over the original non-conformity, and a shed is
considered a more substantial structure than modular decking. Structures such as sheds
located within DUEs and located directly over public utilities such as sanitary sewer
mains would be an encumbrance that would alter the intended use of the easement and
inhibit the proper repair and maintenance of the public utility. As such, the Engineering
Department recommends denial of the second WOAS variance request to add a shed to
the previously approved modular wood deck.
4. The applicant is proposing a variance for a secondary access, or “parking pad”, abutting
Horseshoe Curve. The submittal materials provided by the applicant identify the area of
the proposed parking pad as a “pre-existing” parking pad, however the area identified is
the pre-existing driveway access that was proposed to be removed with the previous
variance submittals along with the removal plans of Grading Permit #21-05 issued on
October 1, 2021. Leaving the pre-existing driveway access while also installing a new
driveway access is the same as having two accesses to a residential property which is
only permitted when the secondary access services a utility facility. Additionally,
secondary driveway accesses are ideally maintained as natural grass to limit the amount
120
of impervious surface in those instances – the parking pad being proposed would be
constructed of concrete. Access management along public right-of-way is maintained to
one access per residential property in order to provide for safe and efficient street
networks. Allowing for parking pads directly abutting a city street increases the risk of
accidents, such as vehicles colliding with obstructions (parked vehicles) directly abutting
the street. Horseshoe Curve is a narrow public road with sharp curves and poor site
lines and adding additional obstructions directly abutting the road could intensify the
risk of accidents. Also, having parked vehicles directly abutting the street along such a
narrow corridor can create maintenance issues during snow emergencies. Lastly, if
parking pads were permitted abutting public streets for residential properties, there are
also concerns with aesthetics of roadway corridors and neighborhoods which can
degrade livability for the community. As such, the Engineering Department
recommends denial of the secondary access, or “parking pad”, variance request.
5. The applicant is proposing a variance for the construction of a 6.5 foot high opaque
privacy fence located in the front yard. If the variance is approved the applicant will be
required to enter into an Encroachment Agreement if the fence is erected within a
public drainage and utility easement. See proposed condition 1 .
Proposed Conditions
1. The applicant shall file for an encroachment agreement with the city for any
encroachments within public drainage and utility easements.

Re:Fence, Parking Pad and Shed Variance at 6609 Horseshoe Curve –
Planning Case #2021-07B
The Water Resources Department has reviewed the Variance submittal for 6609 Horseshoe
Curve. These comments are divided into two categories: general comments and proposed
conditions. General comments are informational points to guide the applicant in the proper
planning of public works infrastructure for this project, to inform the applicant of possible
extraordinary issues and/or to provide the basis for findings. Proposed conditions are
requirements that Water Resources recommends be formally imposed on the applicant in the
final order. Note that references to the “City Standards” herein refer to the City of Chanhassen
Standard Specifications and Detail Plates.
General Comments/Findings
1. The applicant is requesting three variances. One variance for adding a shed to the
previously approved Water Oriented Accessory Structure (WOAS), which includes a side-
yard setback variance, an Ordinary High Water-Level (OHWL) setback variance, and a
WOAS size variance. The other two variances are for a privacy fence and parking pad
located at the front of the property abutting Horseshoe Curve.
2. The property is located on Lotus Lake. According to the Riley-Purgatory Bluff Creek
Watershed District, water quality on Lotus Lake has improved in some parameters, such
122
as water clarity and phosphorus, but degraded in others, such as chlorophyll-a, in recent
years. The project is proposing placing WOAS very close to the lake – approximately 8 ft
away from the waters edge. As such, the applicant is requesting that the new WOAS
extend beyond the 10-foot OHWL setback. This setback is designed to limit the amount
of development or structures that are placed near a lakeshore. This protects the lake
from sediment and erosion issues, while also protecting said structures from possible
flooding issues. The applicant’s existing WOAS encroaches into this OHWL setback,
however, a variance for this deck was approved as it actually decreased the
encroachment into the setback from the previous WOAS (pre-2021). The addition of the
proposed shed would increase the encroachment.
3. In January 2021, a variance was approved to replace an existing, non-conforming WOAS
on the property with a modular deck. This new structure was considered non-
impervious surface whereas the existing, non-conforming WOAS was impervious
surface. Overall, the applicant proposed to reduce the intensity of the existing non-
conformity. As such, the Water Resources Department recommended approval of the
variance request for the non-conforming WOAS. It is the Water Resources Department’s
understanding that construction on the modular deck is complete and that the area is
225.5 square feet which is smaller than that 308 square foot size of the preexisting
WOAS.
4. The applicant is now requesting to construct an 11’ x 12’ (132 square feet) storage shed
at the lakeshore, adjacent to the new modular deck. This shed is proposed to be
contiguous with the deck, meaning that they are to be treated as one structure. The
maximum allowable WOAS allowed by the City Code is 250 square feet. The proposed
shed and recently constructed modular deck, would result in a total WOAS footprint of
approximately 357.5 square feet which is significantly larger than what is allowed by
code and what was previously approved via the variance process.
5. The Department of Natural Resources was contacted as part of the standard agency
coordination for this variance request. The DNR does not believe that storage is reason
enough to grant this variance.
6.The variance request references Chanhassen City Code Sec 20-281 E(2)(f) which reads “As
an alternative for general development and recreational development waterbodies,
water-oriented accessory structures used solely for watercraft storage, and including
storage of related boating and water-oriented sporting equipment, may occupy an area
of up to 400 square feet provided the maximum width of the structure is 20 feet as
measured parallel to the configuration of the shoreline.”as justification for the variance,
howevertheapplicant’s design does not appear to meet the requirements for this section
of code as the proposed structure (combined modular deck and shed) is not solely for
watercraft storage. Furthermore, the proposed design is approximately 32’ in length
which is 12’ longer that the maximum width outlined in city code.
123
7. It appears that the applicant created the lack of storage predicament described in the
variance. During the design process the need for storage could have been prioritized over
the modular deck but the applicant choose to install a deck instead of the storage shed.
Because the area upland of the lake is no longer considered a natural bluff, the applicant
could feasibly design and construct a modular deck combined with a shed that would
meet all WOAS requirements outlined in code including setbacks to adjacent properties,
OHWL, and sanitary sewer lines.
8. The Water Resources Department has no comment on the variance request for a privacy
fence.
9. The Water Resources Department has no comment on the variance request for the
parking pad.
10. It is the opinion of the Water Resources Department that this variance for the WOAS
request should be denied. There appears to be sufficient options for the applicant to
alter the design that would not require a variance. For example, the applicant could
reduce the size of the modular deck to 118 square feet and place the shed (132 square
feet) adjacent to the deck to achieve the 250 square feet size required by city code.
Furthermore, there appears to be sufficient locations to place a WOAS on the property
that would not require variances for side yard setback and setback to the OHWL. In
addition, there does not appear to be sufficient justification for the size of the total
WOAS beyond storage.

RE: Variance Request, 6609 Horseshoe Curve, Chanhassen – Lotus Lake
Dear MacKenzie,
I have had a chance to review the variance request for 6609 Horseshoe Curve in Chanhassen. The applicant is
proposing a variance to the setback and dimensional standards for a water-oriented accessory structure (WOAS)
on Lotus Lake. The proposed WOAS would be an 11-ft by 12-ft storage shed set 8-ft back from the OHWL. The
Chanhassen Shoreland Ordinance allows for one WOAS that shall not exceed 10-ft in height and 250 square feet
in area and is setback 10-ft from the OHWL.
We encourage the applicant to work with the city to make their proposal consistent with Chanhassen Shoreland
Ordinance provisions related to WOAS to ensure the impact to the shoreland zone is minimized to the greatest
extent possible. Deviations from the shoreland ordinance, including the setback and dimensional standards
listed above, are only to be allowed where there are rare and unique circumstances. This is essential in order to
protect important shoreland habitat from erosion and water quality impacts, prevent vegetation destruction
and maintain vegetative structure screening, and to minimize runoff from impervious surfaces.
Thank you for the opportunity to review this variance request.
Sincerely,
Taylor Huinker

Re: Variance Request for 6609 Horseshoe Curve - Planning Case 2021-07B
Dear Planning Commission Members,
We live at 6615 Horseshoe Curve, 3 houses from the 6609 property. Due to a
scheduling conflict, we are unable to attend the March 1 meeting to present
our concerns in person. We do not support any of the requested variances.
Specifically:
The Shed:
We do not support a variance for the WAOS that would expand the footprint of
the new deck structure now in place (20.5ft x 11ft) to encroach, or further
encroach, on side or shoreline setbacks. If square footage is added to reach
250 sqft or a variance is granted to 308 sqft, any additional structure should
not encroach or further encroach on the side or shoreline setbacks. With the
extensive regrading that has been done at the lakefront, there is now ample
space to expand westward and avoid setback encroachments. Any hardship
here has been created by the property owner in their choice to build the new
deck vs a different configuration.
The Security Gate:
We do not support a variance for the proposed security gate. A code
conforming gate can easily be designed and constructed to meet the property
owner’s safety concerns. There is no hardship here.
The Parking Pad:
We do not support a variance for the proposed parking pad. This property will
have sufficient space on the proposed driveway to accommodate a reasonable
number of visitor vehicles.
In reviewing the available documents regarding this property, there does not
appear to be any reason to grant these variances. The plights that the property
owner presents are not due to circumstances unique to the property. The
circumstances cited in the request have been created by the property owner or
they can be handled without any variance.
126
Granting any of these variances infringes on adjacent property owners or the
lakeshore. It will also set a precedent for easing the current rules which are
very reasonable.
We appreciate your consideration of our position on this matter.
Sincerely,
Steve & Jeannie Wanek

SUGGESTED ACTION
The Chanhassen Planning Commission recommends City Council approve Concept PUD 2022-04,
subject to the Conditions of Approval.”
SUMMARY
RSI Marine is requesting Conceptual PUD approval for a mixed use Planned Unit Development (PUD)
which would facilitate the construction of four 20,000-square foot boat storage buildings.
BACKGROUND
In August of 1996 the City Council approved a site plan for the construction of an 8,152-square foot
commercial stable and 12,936-square foot commercial kennel along with conditional use permits
allowing multiple buildings on a single lot and permitting the commercial kennel and stable. Variances
133
allowing metal siding for the stable and a pylon sign were also approved at this time.
In July of 2005, the property was subdivide to create two separate lots, one for each of the principal
buildings.
In 2020, a portion of the property became right-of-way as part of the Highway 101 realignment and the
western building was removed to make way for a construction staging area.
DISCUSSION
The applicant is requesting that the City approve a Conceptual PUD for the parcels northeast of the
intersection of Highway 101 and Highway 61. The applicant is proposing constructing four 20,000-
square foot buildings on the site to be used for indoor boat storage. They have stated that they envision
this as an interim use until City sewer is available. They have noted the proposed use will utilize high
quality finishes, allow for the present improvement and reasonable use of the site, and, due to the nature
of the use, will generate minimal traffic and other impacts. They are proposing a gate, fence, and video
monitoring to provide on-site security. They believe that once full municipal services are available the
site’s use will shift to include a commercial component.
The property’s current Fringe Business (BF) District zoning would allow for the proposed use as an
interim use; however, the property is guided mixed use, a blend of commercial and high-density
residential development, by the City’s 2040 Land Use Plan, and any City approvals must be consistent
with this classification. In this case, the Comprehensive Plan specifies that the allowable zoning for the
mixed use classification is PUD (Planned Unit Development).
Staff believes that the use of PUD zoning for this development will allow the applicant reasonable use
of the parcel until City sewer becomes available. The proposed use meets a need for the community,
generates minimal traffic, has no outdoor storage component, and can meet the City’s design and
landscaping requirements. The applicant has demonstrated the site can adequately provide parking for a
future retail/office/warehousing mix of uses once sanitary sewer is available. In the longer term, the
uses permitted by the PUD will encourage the property to redevelop as mixed use center once the
proposed building’s reach the end of their lifecycle. For these reasons staff supports the Conceptual
PUD.
A full discussion can be found in the attached staff report.
RECOMMENDATION
Staff recommends that the Planning Commission adopt the following motion:
The Planning Commission recommends that the City Council approve the Conceptual PUD, subject to
the conditions of approval."
The recommended conditions of approval can be found in the attached staff report.

LEVEL OF CITY DISCRETION IN DECISION-MAKING:
The City has a relatively high level of discretion in approving Rezonings because the City is
acting in its legislative or policy-making capacity. A rezoning must be consistent with the City’s
Comprehensive Plan.
The City’s discretion in approving or denying a Site Plan is limited to whether or not the
proposed project complies with Zoning Ordinance requirements. If it meets these standards, the
City must then approve the site plan. This is a quasi-judicial decision.
The City’s discretion in approving or denying a Variance is limited to whether or not the
proposed project meets the standards in the Zoning Ordinance for a variance. The City has a
relatively high level of discretion with a variance because the applicant is seeking a deviation
from established standards. This is a quasi-judicial decision.
Notice of this public hearing has been mailed to all property owners within 500 feet.
PROPOSAL/SUMMARY
The applicant is requesting that the City approve a Conceptual PUD for the parcels northeast of

BACKGROUND
In August of 1996 the City Council approved a site plan for the construction of an 8,152-square
foot commercial stable and 12,936-square foot commercial kennel along with conditional use
permits allowing multiple buildings on a single lot and permitting the commercial kennel and
stable. Variances allowing metal siding for the stable and a pylon sign were also approved at this
time.
In July of 2005, the property was subdivide to create two separate lots, one for each of the
principal buildings.
In 2020, a portion of the property became right-of-way as part of the Highway 101 realignment
and the western building was removed to make way for a construction staging area.
EXISTING CONDITIONS
SITE CONSTRAINTS
The parcels are zoned BF with a combined area of 8.33 acres. The property’s existing BF zoning
requires a minimum lot area of 20,000 square feet with a minimum lot frontage of 100 feet, a
minimum lot death of 150 feet, and maximum lot cover of 40 percent; however, this area is
guided for mixed-use development in the City’s 2040 Land Use Plan which requires that the
zoning be changed to PUD. A commercial kennel/stable formerly operated on the site. A well,
retaining walls, an approximately 7,500-square foot asphalt parking area, an approximately
7,000-square foot gravel driveway, an approximately 8,000-square foot building, and an
approximately 360-square foot shed remain from the previous business.
Bluff Creek Corridor
This property is not located within the Bluff Creek Overlay District.
Wetland Protection
138
10500 and 10520 Great Plains Boulevard Concept PUD
March 1, 2022
Page 4
There is/is not a wetland located on the property; however, there is a small mange type 2 wetland
in the ditch south of the property. As the applicant is proposing to utilize the site’s existing
access to Flying Cloud Drive, the proposed development should not impact this wetland;
however, the wetland buffer strip and setbacks for this wetland must be maintained. These
wetlands have a 20 foot minimum buffer strip, 15 foot accessory structure buffer edge setback,
and 30 foot principal structure buffer edge setbacks.
Bluff Protection
There are no bluffs on the property. The property has numerous steep slopes but none of them
meet the City’s definition of a bluff (i.e. a natural topographic features with an elevation change
of 25 feet or greater and a slope of 30 percent or greater).
The Lower Minnesota River Watershed District (LMRWD) also regulates steep slopes and the
applicant will need to verify with the watershed district if the project triggers their Rule F –
Steep Slopes.
Shoreland Management
The property is not located within a shoreland protection district.
Floodplain Overlay
This property is not within a floodplain. A small section of the ditch south of the property is
within the floodplain; however, no portion of the project will take place below the Base Flood
Elevation (721’ contour).
CONCEPT PUD REVIEW
ANALYSIS
The existing zoning of the property, BF, is not consistent with the land use designation of the
property, Mixed. The Comprehensive Plan allows less intensive land uses to remain in place.
However, any approval by the City for development of the property must be consistent with the
Comprehensive Plan.
SURROUNDING ZONING AND USES
The parcels to the east, west, and southeast of the
subject parcel are also zoned BF. The other nearby
parcels are zoned Agricultural Estate (A2) district.
Nearby uses include nonconforming rental housing, a
golf driving range, a used car dealership, a cold
storage facility, and large lot residential properties.
139
10500 and 10520 Great Plains Boulevard Concept PUD
March 1, 2022
Page 5
With the exception of the single-family residences, all of these uses are legal nonconforming,
conditional uses, or interim uses.
LAND USE - ZONING CONSISTENCY
As noted earlier, the parcels are guided for the Mixed
land use category in the City’s 2040 Land Use Plan.
The City’s Comprehensive Plan states that PUD
zoning is the appropriate zoning for this land use
category.
The use of PUD zoning, as proposed by the applicant,
is consistent with the Comprehensive Plan’s land use
designation for these parcels.
JUSTIFICATION FOR REZONING TO PUD
Planned Unit Developments (PUD) provide for increased flexibility to develop a site by relaxing
most normal zoning district standards, but in exchange for this flexibility they allow the City to
require a higher quality and more sensitive development than would occur under traditional
zoning. The City Code requires that PUDs encourage the following:
1. Preservation of desirable site characteristics and open space and protection of sensitive
environmental features, including steep slopes, mature trees, creeks, wetlands, lakes and
scenic views.
Finding. The applicant’s proposal leaves the area of the steep slopes on the western
portion of the property undisturbed. The use of a PUD helps facilitate the consolidation
of development to the property’s less environmentally sensitive area.
2. More efficient and effective use of land, open space and public facilities through mixing
of land uses and assembly and development of land in larger parcels.
Finding. The use of PUD zoning allows for reasonable use of the property in the short
term while facilitating the long-term development of the parcel as a mixed use center
with a blend of complementary uses. The use of PUD zoning allows for multiple
buildings to be placed on a single lot permitting a more efficient and effective use of land
and allowing for shared parking and other synergies between uses.
3. High quality of design and design compatible with surrounding land uses, including both
existing and planned. Site planning, landscaping and building architecture should reflect
higher quality design than is found elsewhere in the community.
Finding. This area is intended to serve as the City’s southern gateway. For this reason,
the PUD ordinance will require that building elevations facing Highway 61 will exceed
140
10500 and 10520 Great Plains Boulevard Concept PUD
March 1, 2022
Page 6
the City’s minimum design standards. Proposed buildings will be reviewed through the
site plan review process and be required to comply with standard and all other applicable
standards.
4. Sensitive development in transitional areas located between different land uses and along
significant corridors within the city will be encouraged.
Finding.The mix of uses permitted by the PUD will allow for this development to
create sensitive transitions between the mixed uses permitted near the intersection
Highway 101 and Highway 61 and the future high density residential areas to the east of
this site.
5. Development which is consistent with the Comprehensive Plan.
Finding. The use of PUD zoning sets up the framework for the property to develop as a
true mixed-use district including retail, office, storage, and residential uses once sanitary
sewer becomes available to the site, while allowing immediate use of the site as storage
facility. Traditional zoning would not be able to accommodate both the short- and long-
term usage of the site in a manner consistent with the Comprehensive Plan.
6. Parks and open space. The creation of public open space may be required by the City.
Such park and open space shall be consistent with the Comprehensive Park Plan and
overall trail plan.
Finding. The Comprehensive Park Plan does not propose public lands in this area. The
preservation of open space and undisturbed areas on the site is facilitated by the
consolidation of development allowed by the use of PUD zoning, particularly the ability
to place multiple buildings on a single lot.
7. Provision of housing affordable to all income groups if appropriate with the PUD.
Finding.Not applicable as part of this development.
8. Energy conservation through the use of more efficient building designs and sitings and
the clustering of buildings and land uses.
Finding. Energy conservation will be facilitated through the clustering of buildings on a
single lot.
9. Use of traffic management and design techniques to reduce the potential for traffic
conflicts. Improvements to area roads and intersections may be required as appropriate.
Finding. Appropriate traffic management techniques will be used. The developer and
site users will be required to use traffic demand management strategies as appropriate.

building elevations facing Highway 61 will exceed the minimum standards
established by Division 7 and 9 of Article XXIII of the City Code
SITE PLAN REVIEW
The applicant is proposing four 20,000-square foot buildings which will be used for indoor boat
storage. The applicant has stated that the site will have no outdoor storage or exterior trash
receptacles. The applicant has stated that they intend to use tilt up concrete panels and other high
quality finishes on the visible sides of the property.
ARCHITECTURAL COMPLIANCE
Size Portion Placement
The applicant has indicated that the buildings will
be arranged so that the storage bays face the
interior of the development. Due to the proposed
use, the buildings are not anticipated to have a
traditional main entryway, nor is it desirable for
the building’s entrances to face the public streets;
however, the use of recessed entries, awnings, or
other means of articulation is encouraged. If
entries are proposed facing a public street, it is the
City’s expectation that they be articulated in a
manner consistent with the requirements of the
City’s design standards.
143
10500 and 10520 Great Plains Boulevard Concept PUD
March 1, 2022
Page 9
The applicant is proposing using tilt up panels for the visible portions of the development. The
City Code requires that buildings of more than 40 feet in width be divided into increments
between 20 and 40 feet wide through articulation of the façade. The applicant can achieve this
either through façade modulation or potentially through the use of vertical division using
different textures or materials.
Material and Detail
The use of tilt up concrete panels
that are grid or brick like in
appearance would meet the City’s
material and detail requirements.
Smooth panels would not be
permitted for the sections of the
building visible from public roads.
The applicant would be able to use
accent materials such as metal, glass
block, spandrel glass, or similar
materials approved by the City so
long as they make up no more than
15 percent of the building’s façade.
Color
The applicant has not provided a proposed color palette; however colors shall be harmonious.
Building colors shall consist of muted colors with low reflectance. Recommended colors include
browns, grays, tans, beiges and dark or muted green, blues and reds. Bright or brilliant colors and
sharply contrasting colors may be used only for accent purposes occupying a maximum of ten
percent of building facades.
Height and Roof Design
The applicant has indicated the buildings will be one story with a likely height of around 16 feet.
Any mechanical equipment located on the roof will need to be 100 percent screened from public
144
10500 and 10520 Great Plains Boulevard Concept PUD
March 1, 2022
Page 10
view, either through the use of architectural elements such as parapet, landscaping that will be
effective in the winter, or location. The applicant should include pitched elements (roof,
awnings, entries, etc.) to the maximum extent practicable and, if a flat roof is utilized, an
ornamental parapet or cornice should be present to help define the roof.If any roof mounted
mechanical equipment is present, it shall be screened from public view.
Note: The above image illustrates a variety of techniques that can be used to meet the
requirement of the City’s design standards. Staff recognizes that due to the nature of the
proposed use, the fenestration standards will be reduced through the methods discussed in the
following section.
Facade Transparency
While the City typically requires that 50 percent of the first floor elevation viewed by the public
include transparent elements such as windows or doors, with other areas including landscaping
materials and architectural detailing and articulation, the City Code allows for warehouses to
have reduced fenestration standards. This reduction must be offset by the use of spandrel glass or
architectural detailing which provides arches, patterning, recesses and shadowing that provide
aesthetic interest. The applicant will need to demonstrate that the design of the building
elevations visible from public streets meets the requirements of this ordinance.
Site Furnishing
The nature of the applicant’s proposal makes the inclusion of benches, tables, and chairs
impractical.
Fence
The applicant is proposing a fence to help secure the site. The City Code restricts commercial
and industrial fences to a maximum height of eight feet. If the proposed fence does not meet the
definition of an open fence, it must be located outside of the required front yard setbacks and
sight distance triangle. The fence should also be located behind the required landscape buffers.
145
10500 and 10520 Great Plains Boulevard Concept PUD
March 1, 2022
Page 11
Loading Areas, Refuse Area, Etc.
The applicant has stated that no external trash enclosures will be present on the property. All
storage bays will be oriented towards the interior of the development and will be minimally
visible from public streets.
Lot Frontage and Parking Location
The applicant is not proposing locating any parking between the buildings and the primary street.
The applicant has shown approximately 69 parking stalls located between the building’s stalls
and the side street; however, this lot area is provided to show proof of parking for when the site
redevelops to include non-storage uses. The exact amount, location, and configuration of the
site’s parking would be determined at that time based on the mix of uses.
ACCESS
The applicant is proposing using the existing access to Flying Cloud Drive. Access to the site is
currently had from Flying Cloud Drive (CSAH 61) and is located near the western property line.
The preliminary plans indicate that the current access will remain and no additional accesses to
the surrounding Carver County rights-of-way are proposed. The development will be required to
construct a commercial driveway access in accordance with City standards. Any comments or
conditions by Carver County associated with impacts to their rights-of-way must be adhered to
and all permits required must be obtained prior to construction activities commencing.
It appears no turnaround is provided in the preliminary plans. In accordance with Section 20-
1122 of City Code, a turnaround is required when access is had from a state highway, county
road or collector roadway. As access is being had from CSAH 61, a turnaround will be required
that can adequately facilitate the turning movement of the largest anticipated design vehicle for
the site or the City’s largest fire truck, whichever is greater.
EASEMENTS
The applicant is proposing to vacate the existing easements and to dedicate 10-foot drainage and
utility easements along the perimeter of the combined parcel. Additional drainage and utility
easements will be required over public utilities (i.e. water main) extended into the property. The
exact dimensions of the water main drainage and utility easements will be determined by the
location and depth of the water main; however, the minimum is typically a 20-foot wide
easement centered over the main.
GRADING AND DRAINAGE
The existing conditions plan sheet and drainage maps included in the Conceptual PUD submittal
show an existing building near the center of the property with access to Great Plains Boulevard
provide by an asphalt parking area and gravel driveway. Stormwater runoff generally flows from
north to south down the slope of the site where it enters a drainage swale along Flying Cloud
146
10500 and 10520 Great Plains Boulevard Concept PUD
March 1, 2022
Page 12
Drive. The drainage swale conveys stormwater from west to east. Stormwater leaves the site by
way of an existing 48” culvert under Flying Cloud Drive which conveys the stormwater to the
South through Bluff Creek and ultimately outleting to the Minnesota River.
The preliminary plans provided with the Conceptual PUD submittal show a significant amount
of grading. The design steepens the hill on the northeast side of the site to create a flat area
conducive for the four proposed buildings with access and parking. The proposed design uses a
combination of drainage swales and stormwater infrastructure to collect and convey stormwater
into a Best Management Practice (BMP) located on the southwest corner of the property. The
design shows stormwater being conveyed from the proposed BMP to the existing swale along
Flying Cloud Drive through an outlet control structure. Any impacts to Carver County’s right-of-
way must be approved and permitted by the County prior to construction activities. The overall
design of the stormwater infrastructure mimics the flow path of the existing condition and acts to
convey stormwater runoff from impervious surfaces through water quality BMPs. A more
detailed analysis of stormwater volumes and rates may be required to show the wetland onsite is
not negatively impacted by the proposed design.
EROSION CONTROL
The proposed development will exceed one (1) acre of disturbance and will, therefore, be subject
to the General Permit Authorization to Discharge Stormwater Associated with Construction
Activity Under the National Pollution Discharge Elimination/State Disposal System (NPDES
Construction Permit). The applicant has prepared and submitted a preliminary Surface Water
Pollution Prevention Plan (SWPPP) and generally appears feasible. The SWPPP is a required
submittal element for preliminary plat review. No earth disturbing activities may occur until an
approved SWPPP is developed. This SWPPP shall be a standalone document consistent with the
NPDES Construction Permit and shall contain all required elements as listed in Parts III and IV
of the permit. The SWPPP will need to be updated as the plans are finalized, when the
contractor and their sub-contractors are identified and as other conditions change.
RETAINING WALLS
The applicant is proposing several retaining walls. Smooth face concrete, masonry, railroad ties,
and timber may not be used for the construction of the retaining walls. Any walls over four feet
in height will require a building permit and engineered design. Any walls under four feet in
height will require a zoning permit. It should be noted that the height of any retaining wall is
measured from the top of the wall to the bottom of the footing (not to the top of grade adjacent to
the bottom of the wall). Any walls located in a drainage and utility easement will require an
Encroachment Agreement.
Portions of the retaining walls are illustrated to be either close to or directly over the western
property line. Due to the proximity to the property line, the construction of these walls would
require construction activities to occur on the abutting property. The construction of any
improvements that impact or require access to abutting properties must have the appropriate
147

right-of-entry agreements and/or temporary construction easements prior to construction
operations commencing.
LANDSCAPING
A Planned Unit Development (PUD)
is expected to ‘protect… mature
trees…” and ‘reflect higher quality
design of…landscaping’. The
proposed development site has
existing trees as evidenced in a field
inspection and shown in current
aerial mapping applications. The
existing trees and woods are not
included on the Existing Conditions
sheets, nor reflected in the submitted
Canopy Coverage calculations shown
on the Landscape Plan. It is
unknown if any of the existing trees
will be preserved, but it appears that
there may be some in part of the ‘undisturbed area’ shown on the plan that may possibly be
unaffected by site grading. The applicant will need to submit a tree inventory for the site as well
as update the canopy coverage calculations. Based on the calculations, the applicant will need to
meet and potentially exceed the minimum requirements for replacement tree planting on the site.
Staff recommends that the applicant consider using a no-mow turf grass or prairie mix in place of
the proposed sod areas to promote a sustainable landscape design for the site.

The applicant does not meet minimum requirements for buffer yard plantings on the site. The
vehicular-use area is required by Code to have landscaping that includes islands or peninsulas for
every 6,000 square feet of use area and landscape areas and a minimum number of trees in and
around the parking area in order to reduce the overall heat island effect of pavement and improve
aesthetics of the site. Minimum requirements for landscaping for the parking lot include 2,816
square feet of landscaped area around the parking lot, five landscaped islands or peninsulas, and
11 trees for the parking lot. The applicant’s proposed as compared to the requirements for
landscape area and parking lot trees is shown in the following table:
Required Proposed
Vehicular-use landscape
area
2,816 sq. ft.0 sq. ft.
Trees/parking lot 11 trees 0 trees
Landscape islands or
peninsulas/parking lot
5 islands/peninsulas 0 islands/peninsulas
The landscaping as proposed in the concept plan does not meet minimum requirements for trees,
landscaping or islands/peninsulas. Acknowledging that the standard requirements for trees and
landscape islands within the paved area may prove difficult to incorporate into the site, staff
recommends that the applicant propose alternatives that also provide environmental benefits
and/or reduction in the heat island effect caused by large expanses of asphalt.
LIGHTING/SIGNAGE
The applicant has stated that site lighting will be downcast and minimal with virtually no light
leaving the property line. The applicant will need to demonstrate compliance with the City’s
lighting ordinance as part of the site plan review process. The use of motion activated lights to
aide in site security is encouraged.
The development will be subject to the requirements of the City’s Sign Code for the General
Business (BG) District. The proposed PUD ordinance would also require that all signage be
architecturally compatible with buildings’ materials and colors.
MISCELLANEOUS
The buildings will need to have fire sprinkler systems installed and fire panel(s) to facilitate
monitoring the sprinkler systems. Hydrants will be required and the fire access roads/driveway
grades may not exceed 10 percent.
If an HVAC system is required, any and all exterior components will need to be screened from
public view, either through the use of materials similar to the building materials or by using
heaving landscaping that will be effective in winter.

Carver County property information shows two parcels abutting the preliminary plat’s western
property lines that are listed as “Parcel ID: Gap”. The status of these parcels must be clarified
prior to the recording of the proposed plat.
PARKS
In 2005, a Stipulation of Settlement (Court File No. 10-CV-05-48) between PCH Development,
LLC and the City of Chanhassen was agreed to regarding the Park Dedication fees and Surface
Water Management fees surrounding the subdivision of the “Paws Claws and Hooves Addition”
subdivision (Planning Case #2003-04 and the property of this Conceptual PUD). The park fee
was reduced to $2,800. The settlement agreement states, “If all or any part of the property is
changed to a different principal use or further subdivided, the property shall be subject to
payment of additional Park Dedication and Surface Water Management fees based upon the rates
in effect at that time applicable to the proposed use and type of municipal approval requested.”
However, as the stipulation was between the property owner and the City and was not required to
be memorialized against the property, if the property owner changes from PCH Development,
LLC, no park fees will be required if the PUD is approved. If the property is subdivided in the
future, park fees will be collected at the rate in affect at the time of platting, minus the $2,800.00
already paid.
STORMWATER MANAGEMENT
The project site is located within the Lower Minnesota River Watershed District (LMRWD). The
LMRWD is the LGU that administers NPDES Construction Permits for stormwater
management. The proposed development will exceed the one (1) acre of new impervious area
and will therefore require permanent stormwater BMPs to be constructed as part of this project
and maintained by the owner. The project will be subject to stormwater regulations outlined
under LMRWD Rule D including rate, volume, and water quality.
The City of Chanhassen also regulates the design, construction, and maintenance of stormwater
infrastructure. Article VII, Chapter 19 of City Code describes the required stormwater
management development standards. Section 19-141 states that “these development standards
shall be reflected in plans prepared by developers and/or project proposers in the design and
layout of site plans, subdivisions and water management features.” A stormwater maintenance
agreement and associated operations and maintenance plan is required for all private stormwater
BMPs.
Preliminary plans provided with the Conceptual PUD submittal show stormwater treatment and
rate control from a wet pond with an incorporated filtration bench BMP located on the southwest
corner of the property. The stormwater BMP appears to be properly sized for the impervious
surface proposed in the plans. The design of the BMP is highly dependent on soil types and
infiltration rates of the underlying soils. Soil borings, infiltration testing and an associated
geotechnical report will be needed to confirm the design of the stormwater BMP. No
geotechnical report was included as part of the Conceptual PUD submittal.
151

March 1, 2022
Page 17
The City’s Water Resources Engineer reviewed the preliminary plans provided with the
Conceptual PUD. Specific comments regarding the design of stormwater infrastructure and
BMPs were provided to the applicant.
In 2005, a Stipulation of Settlement (Court File No. 10-CV-05-48) between PCH Development,
LLC and the City of Chanhassen was agreed to regarding the Park Dedication fees and Surface
Water Management fees surrounding the subdivision of the “Paws Claws and Hooves Addition”
subdivision (PC #2003-04 and the property of this Conceptual PUD). The Surface Water
Management fee was reduced to $9,900.00 and was paid on July 25, 2005. The settlement
agreement states, “If all or any part of the property is changed to a different principal use or
further subdivided, the property shall be subject to payment of additional Park Dedication and
Surface Water Management fees based upon the rates in effect at that time applicable to the
proposed use and type of municipal approval requested.” However, as the stipulation was
between the property owner and the City and was not required to be memorialized against the
property, if the property owner changes from PCH Development, LLC, no stormwater fees will
be required if the PUD is approved. If the property is subdivided in the future, stormwater fees
will be collected at the rate in affect at the time of platting, minus the $9,900.00 already paid.
UTILITIES
Currently, municipal sanitary sewer and potable water services are not available to the site.
During the build-out of the Highway 101 Realignment project, which was substantially
completed in 2021, public sanitary sewer mains and water mains were extended along the
corridor. However, these newly extended utilities are not fully active nor ready for operation to
service properties, as such the site does not have adequate public sanitary sewer and water to
fully serve the development’s needs.
With a lack of adequate City utilities in the area, the development will be required to provide
private utility services (sanitary sewer and potable water) to adequately meet the needs of the
development. The City has preliminarily agreed to allow the development to tap into the public
water main which was extended with the Highway 101 Realignment project, but only to service
the development’s fire suppression needs. At this time there is no sufficient demand along the
extended water main to supply water to the quality standards that the City requires for
consumption. This is important to note because the preliminary plans provided indicate the
existing well on site is proposed to be abandoned. If the site will have any fixtures requiring the
use of water other than for fire suppression needs, a private source of water supply must be used
for those fixtures.
The preliminary plans indicate tapping of the existing public water main for fire suppression
needs at the southwest corner of the property. As shown on the preliminary plans, this would be
infeasible as the water main was housed in a casing at the location, and would be required to be
extended further west to facilitate the connection. Regardless, the development will be required
to extend the public water main to the western property line, and the extension into the site must
be along or near the improved private access to allow for reasonable access for future repair and
152
10500 and 10520 Great Plains Boulevard Concept PUD
March 1, 2022
Page 18
maintenance. Adequate public drainage and utility easements will be required over the public
main as it extends into the site. Private fire laterals can then be tapped from the public main as
necessary.
The property and potential future properties associated with this developable area will be
specially assessed for the extension of the public sanitary sewer when they connect. A rough
estimate of potential fees is provided below; however, it should be noted that the final fee will
depend on the actual project costs:

Note: Listed “Code” parking setbacks can be reduced to 10 feet if 100 percent screening is
provided at least five feet above the parking lot. This screening must be in the form of berms and
landscaping.
VARIANCE REVIEW
The applicant is requesting a variance to use a holding tank in lieu of a septic system. Currently,
the site does not have access to the City’s sanitary sewer system and the site’s use does not
require the permanent presence of an employee. Since employees would only be present to drop
off and pick up boats, the site will likely only require a single bathroom. Given low volume of
waste that the site will generate and the fact that the site will be required to hook up to City
sewer once it becomes available, requiring a full-fledged septic system would be excessive and
unnecessary.
RECOMMENDATION
Staff recommends that the Planning Commission adopt the following motion:
The Planning Commission recommends that the City Council approve the Concept PUD, subject

RSI Marine is a full service boat storage and Marina owner (Carribean Marina Lake Minnetonka).
Storage locations are scattered around the Twin Cities. We are proposing four buildings 20,000 each
with an estimated 80,000 square feet of buildings. We are proposing tilt up panels and other high
quality finishes on all visible sides of the property. These buildings will be used for indoor boat storage
until city sewer service is extended to the property.
There will be no outside storage nor will there be any Residential use in the complex. The site
will have video security, gate and fence. This site will have minimal traffic and noise because of the use.
Site lighting will be downcast and minimal with almost nothing at the property lines. No hazardous
waste material storage is allowed. No exterior storage is allowed on the site. We do not have any trash
receptacles allowed outside.
This use will in our opinion be an exceptional interim use until city sewer is extended. At that point we
feel the “market ” for commercial/retail will be stronger here due to the market forces that will push the
extension of city services. At this point we will work with Commercial Real Estate professionals to
convert these buildings to other uses that align with the Comp Plan and the market. In the interim we
will be able to enhance the property thus making the entire area more desireable.
Upon final development of this project once city services are extended we feel it will be valued at over
200psf when complete.
We would like to thank you for your consideration of our project.

ESTIMATED EROSION AND SEDIMENT CONTROL QUANTITIES
RSI MARINE - CHANHASSEN, MN
TYPE OF PROJECT: COMMERCIAL DEVELOPMENT
TYPE OF WORK: Mass Grading, Utility and Street Construction,
Paving. Subsequently, Joint Trench and Home construction will
occur.
TOTAL PLATTED AREA: 8.33 AC
TOTAL DISTURBED AREA: 6.26 AC
PROPOSED (DESIGN) IMPERVIOUS AREA:2.83 AC
SPECIAL WATERS: The site is NOT within a 1-mile radius of a
special or impaired water.
CONSTRUCTION PHASING
The project is expected to be constructed in three phases, with mass
grading occurring during one construction season. Mass grading is
anticipated to be completed within 4 weeks from commencement of
work. Utility and street construction is anticipated to be completed
within 4 weeks from commencement of work.
POTENTIONAL FOR EROSION AND DISCHARGE OF SEDIMENT
As the site will be stripped of topsoil and vegetation for a period of
several weeks during construction, the potential for erosion will
increase. The overall gradients on the site are relatively low. The
street subcut will serve as temporary sediment basins during
construction. The project is primarily cut, and therefore perimeter
erosion will flow inward towards the project.
The risk of discharge of sediment off of the site is low, due to the
grade orientation and design. The highest potential for discharge off
the site is from the street entrance.
Contractor will be required to manage completion of 3:1 slopes such
that soil exposure is minimized. After excavation and embankments
are completed, slopes shall be re-spread with topsoil, the slope
grades certified, and erosion blanket installed as per the plan.
Contractor shall coordinate these steps to be carried out in a timely
manner.
EROSION CONTROL BMPs
The construction plans anticipate the use of, but are not limited to, the
following Erosion Control BMPs:
1.Perimeter delineation to minimize disturbed areas
2.Temporary Rock Construction Entrance
3.Temporary straw mulch as needed.
4.Seed and mulch/sod
5.Erosion Control Blanket
6.Minimize active or disturbed work areas
7.Horizontal slope grading
8.Turf Reinforcement Mat
SEDIMENT CONTROL BMPs
The construction plans anticipate the use of, but are not limited to, the
following Sediment Control BMPs
1.Sediment traps constructed in street subcut
2.Rock filter dikes in street subcut
3.Utilize permanent stormwater basin as Temporary Sediment
Basin
4.Silt Fence at project perimeter or toe of slopes
5.Inlet protection on existing catch basins
6.Inlet protection on existing culverts
7.Inlet protection after utility construction
8.Linear control along back of new curb and gutter (sod, bioroll, or
silt fence)
9.Routine street sweeping adjacent to construction entrance.
10.Ditch checks
Refer to plans for designated locations of BMPs, details and
implementation notes.
BASIN AND TRAP DEWATERING BMPs
Should the need arise for basin or trap dewatering, contractor shall
utilize a floating skimmer pump intake, such that the water is drawn
from the surface of the basin. Pumped effluent shall not be
discharged into Surface Waters in a turbid state.
Turbid effluent shall be filtered with mechanical devices, chemical
filtering, or a combination thereof, to a state of 50 NTUs or less.
STABILZATION BMPs
The construction plans anticipate the use of, but are not limited
to, the following Stabilization BMPs:
1.After lot pads are grade certified, permanent seed and
mulch can be applied, generally from the front of the
building pad, extending to the rear of the lot (areas where
no further utility construction is anticipated.)
2.After 3:1 slopes on lots are certified, permanent seed and
erosion control blanket can be applied.
3.Rip rap at pipe outfalls
4.Permanent seed and erosion control blanket on basin
slopes after grade certified.
5.After curbs are backfilled, apply permanent seed and
mulch to remaining building pads and boulevard area not
already stabilized.
6.Sod placement, as appropriate.
POLLUTION CONTROL BMPs
1.Fueling: A fixed fueling station is not anticipated.
Contractor will be required to implement BMPs for onsite
re-fueling of equipment.
2.Concrete Washout: A suggested washout area will be
specified on the plan. The developer has the ability to
adjust location or to provide alternative washout
containment.
3.There is not an anticipated need for storing chemicals,
paints, solvents or other potentially toxic or hazardous
materials on site.
SEED & MULCH SPECIFICATIONS
Seed placed for permanent cover or final stabilization requires
6” minimum topsoil cover. Exception: Infiltration basins - see
basin details for soil type). Multiple site visits will be required
to accommodate permanent or temporary stabilization as
required during the phases of construction.

INSPECTION AND MAINTENANCE OF BMPs
Routine Inspection
1.Rock Entrance - Inspect weekly. If rock becomes filled
with sediment and tracked material to the extent the
purpose ceases to function, remove the contaminated
rock and replace with new rock.
2.Silt fence - Inspect weekly, particularly for damaged
sections, breaches, down-gradient areas, flow
concentration points, scour areas and sections adjacent to
sensitive areas. Where capacity is filled to more than 50%
of depth, sediment shall be removed to restore capture
capacity.
3.Sediment traps and basins - Inspect weekly. Where
capacity is filled to more than 50% of depth, sediment
shall be removed to restore capture capacity within 72
hours of discovery.
4.Inlet Protection - Inspect weekly or more frequently as
needed after multiple rainfalls less than 0.5”. Verify intake
capacity is not compromised. Where capacity is filled to
more than 50% of depth, sediment shall be removed to
restore capture capacity.
5.Inspect other site specific BMP's on a weekly basis
minimum.
Rain Event Inspection - Mandatory, within 24 hours after a rain
event 0.5” or greater. Complete all items associated with
Routine Inspection. Furthermore, inspect site for breaches,
failures, scours and gullying. Take corrective actions as
necessary to restore functionality to the BMP's. If a given
situation is discovered to be prone to repetitive failure, advise
the Engineer and Contractor for SWPPP and BMP
amendments.
ADDITIONAL SWPPP NOTES
1.All Erosion and Sediment Control facilities shall be
maintained by the contractor during the construction
operations. Any temporary facilities which are to be
removed as called for on these plans and specifications
shall be removed by the contractor at the time directed by
the engineer. The contractor shall then restore the
subsequently disturbed areas in accordance with these
plans and specifications.
2.Wherever practical and feasible, the contractor shall
protect and preserve existing natural trees, grass and
other vegetative cover in effort to provide natural buffering
and filtering of runoff.
3.Contractor shall be adaptable in adjusting construction
schedules in anticipation of weather forecasts of
precipitation, in order to minimize risk of erosion and
sediment transport.
4.It is the responsibility of the contractor to keep public
streets, travel ways, parking lots and trails utilized for
ingress to and egress from the construction site free of
dirt, sediment and debris, resulting from construction
activity. Cost for this shall be considered incidental to the
contract.
5.Adequate control of dust shall be maintained by the
contractor. Cost for dust control shall be considered
incidental to the contract.
ADDITIONAL SWPPP NOTES (continued)
6. Perimeter controls shall not be removed until final
stabilization of areas draining toward the control devices.
7. When temperatures do not exceed 40 degrees F, areas
that require seed and mulch stabilization shall be dormant
seeded. Application rate shall be two times the normal rate.
No dormant seeding shall be done on ice or snow greater
than 2” in depth.
8. Any areas that were seeded that do not achieve 70%
coverage shall be reseeded at the contractor's expense,
where coverage limitation is caused by lack of seed
germination and growth.
MPCA STORMWATER PERMIT - RESPONSIBILITY
The Contractor will be required to become the Permittee for the
project, until final stabilization and transfer of responsibility is
completed. Transfer of responsibility shall be completed with the
Permit Modification Form.

1.1 Permit Coverage. [Minn. R. 7090]
1.2 This permit is required for construction activity that results in land disturbance of equal to or greater than
one (1) acre or if a project is part of a common plan of development or sale that ultimately will disturb
greater than one (1) acre, and authorizes, subject to the terms and conditions of this permit, the discharge
of stormwater associated with construction activity. [Minn. R. 7090]
1.3 Construction activity covered by this permit cannot commence until coverage under this permit is effective
as described in item 3.3 through 3.4 or, if applicable, until the Minnesota Pollution Control Agency (MPCA)
has issued an individual National Pollutant Discharge Elimination System (NPDES)/State Disposal System
SDS) construction stormwater permit for the project. [Minn. R. 7090]
1.4 This permit covers all areas of the State of Minnesota except land wholly within the boundaries of a
federally recognized Indian Reservation owned by a tribe or a tribal member or land held in trust by the
federal government for a tribe or tribal member. [Minn. R. 7090]
1.5 Coverage under this permit is not required when all stormwater from construction activity is routed
directly to and treated by a "treatment works," as defined in Minn. Stat. Sect. 115.01, subd. 21, operated
under an individual NPDES/SDS permit with a Total Suspended Solids (TSS) effluent limit. [Minn. R. 7090]
1.6 This permit covers ongoing projects covered under any previous construction stormwater permit that are
not complete on the issuance date of this permit. Permittees must either remain in compliance with the
previous permit and terminate coverage within 18 months of the issuance date of this permit or comply
with this permit, including updating the Stormwater Pollution Prevention Plan (SWPPP), within the 18-
month period. Permittees of previously permitted projects are not required to incorporate any additional
requirements regarding the permanent stormwater treatment system included in this reissued permit.
Minn. R. 7090]
1.7 Coverage for projects that extend beyond the expiration date of this permit remains effective for a grace
period covering project completion and Notice of Termination (NOT) submittal. If Permittees cannot
complete projects during the grace period, the MPCA will extend coverage under the next permit and
permittees must comply with the requirements of the new permit including updating the SWPPP.
Permittees are not required to follow changes to the permanent stormwater treatment section of the next
permit. [Minn. R. 7090]
2.1 Prohibitions and Limitations of Coverage. [Minn. R. 7090]
2.2 The owner must develop a complete and accurate SWPPP that complies with item 5.2 prior to submitting
the application for coverage and starting construction activity. Failure to prepare a SWPPP prior to
submitting the application may result in permit revocation. [Minn. R. 7090]
2.3 This permit prohibits discharges of any material other than stormwater treated in compliance with this
permit and discharges from dewatering or basin draining activities in accordance with Section 10.
Prohibited discharges include, but are not limited to, wastewater from washout of concrete, stucco, paint,
form release oils, curing compounds and other construction materials, fuels, oils, or other pollutants used
in vehicle and equipment operation and maintenance, soaps or solvents used in vehicle and equipment
washing and maintenance, and other hazardous substances or wastes. [Minn. R. 7090]
2.4 This permit does not authorize stormwater discharges related to the placement of fill into waters of the
state requiring local, state or federal authorizations (such as U.S. Army Corps of Engineers Section 404
permits, Minnesota Department of Natural Resources (DNR) Public Waters Work permits or local
governmental unit (LGU) Wetland Conservation Act replacement plans or determinations). [Minn. R. 7090]
2.5 This permit does not authorize stormwater discharges associated with industrial activity except for
construction activity. Permittees must obtain coverage for discharges associated with industrial activity
under a separate NPDES/SDS permit once day-to-day operational activities commence even if construction
is ongoing. [Minn. R. 7090]
2.6 This permit does not authorize discharges from non-point source agricultural and silvicultural activities
excluded from NPDES permit requirements under 40 CFR pt. 122.3(e). [Minn. R. 7090]
2.7 This permit does not authorize stormwater discharges to Prohibited, Restricted, Special or Impaired waters
unless permittees follow the additional stormwater requirements in Section 23. [Minn. R. 7090]
2.8 This permit does not replace or satisfy any environmental review requirements including those under the
Minnesota Environmental Policy Act or the National Environmental Policy Act. The owner must verify
completion of any environmental review required by law, including any required Environmental
Assessment Work Sheets or Environmental Impact Statements, Federal environmental review, or other
required review prior to applying for coverage under this permit. If any part of your common plan of
development or sale requires environmental review, coverage under this permit cannot be obtained until
such environmental review is complete. [Minn. R. 7090]
2.9 This permit does not replace or satisfy any review requirements for discharges adversely impacting State
or Federally designated endangered or threatened species or a designated critical habitat. The owner must
comply with the National Historic Preservation Act and conduct all required review and coordination
related to historic preservation, including significant anthropological sites and any burial sites, with the
Minnesota Historic Preservation Officer. [Minn. R. 7090]
2.10 This permit does not authorize discharges to wetlands unless the permittee complies with the
requirements in Section 22. [Minn. R. 7090]
3.1 Application and Coverage Effective Date. [Minn. R. 7090]
3.2 The owner and operator must submit a complete and accurate on-line application with the appropriate fee
to the MPCA for each project that disturbs one (1) or more acres of land or for a common plan of
development or sale that will ultimately disturb one (1) or more acres. [Minn. R. 7090]
3.3 For projects or common plans of development or sale that disturb less than 50 acres or do not discharge
stormwater within 1 mile (aerial radius measurement) of a special or impaired water, permittees do not
need to submit the SWPPP with the application. Permit coverage for these projects is effective upon
application and completing the payment process. [Minn. R. 7090]
3.4 For certain projects or common plans of development or sale disturbing 50 acres or more, the complete
SWPPP must be included with the application and submitted at least 30 days before the start of
construction activity. This applies if there is a discharge point on the project within one mile (aerial radius
measurement) of, and flows to, a special water listed in item 23.3 through 23.6 or an impaired water as
described in item 23.7. Permit coverage for these projects is effective upon submitting the application and
complete SWPPP, completing the payment process and receiving a determination from the MPCA that the
review of the SWPPP is complete. The determination may take longer than 30 days if the SWPPP is
incomplete. If the MPCA fails to contact the permittees within 30 days of application receipt, coverage is
effective 30 days after completing the payment process. [Minn. R. 7090]
3.5 The application requires listing all persons meeting the definition of owner and operator as permittees.
The owner is responsible for compliance with all terms and conditions of this permit. The operator is
responsible for compliance with Sections 3, 4, 6-22, 24 and applicable requirements for construction
activity in Section 23. [Minn. R. 7090]
3.6 Permittees will receive coverage notification in a manner determined by the MPCA. [Minn. R. 7090]
3.7 For construction projects where the owner or operator changes (e.g., an original developer sells portions
of the property to various homebuilders or sells the entire site to a new owner), the current owner and the
new owner or operator must submit a complete permit modification form provided by the MPCA. The
current owner and the new owner or operator must submit the form prior to the new owner or operator
commencing construction activity or no later than 30 days after taking ownership of the property. [Minn.
R. 7090]
3.8 For construction projects where the owner or operator changes, the current owner must provide a SWPPP
to the new owner and operator that specifically addresses the remaining construction activity. The new
owner or operator can implement the original SWPPP, modify the SWPPP, or develop a new SWPPP.
Permittees must ensure their activities do not render another party's erosion prevention and sediment
control BMPs ineffective. [Minn. R. 7090]
4.1 Termination of Coverage. [Minn. R. 7090]
4.2 Permittees must submit a NOT within 30 days after all termination conditions listed in Section 13 are
complete. [Minn. R. 7090]
4.3 Permittees must submit a NOT within 30 days after selling or otherwise legally transferring the entire site,
including permit responsibility for roads (e.g., street sweeping) and stormwater infrastructure final clean
out, or transferring portions of a site to another party. The permittees' coverage under this permit terminates at
midnight on the submission date of the NOT. [Minn. R. 7090]
4.4 Permittees may terminate permit coverage prior to completion of all construction activity if they meet all
of the following conditions:
a. construction activity has ceased for at least 90 days; and
b. at least 90 percent (by area) of all originally proposed construction activity has been completed and
permanent cover has been established on those areas; and
c. on areas where construction activity is not complete, permanent cover has been established; and
d. the site complies with item 13.3 through 13.7.
After permit coverage is terminated under this item, any subsequent development on the remaining
portions of the site will require permit coverage if the subsequent development itself or as part of the
remaining common plan of development or sale will result in land disturbing activities of one (1) or more
acres in size. [Minn. R. 7090]
4.5 Permittees may terminate coverage upon MPCA approval after submitting information documenting the
owner cancelled the project. [Minn. R. 7090]
5.1 Stormwater Pollution Prevention Plan (SWPPP) Content. [Minn. R. 7090]
5.2 The owner must develop a SWPPP. The SWPPP must include items 5.3 through 5.26. [Minn. R. 7090]
5.3 The SWPPP must incorporate specific Best Management Practices (BMP) used to comply with the
requirements of this permit. [Minn. R. 7090]
5.4 The SWPPP must include a narrative describing the timing for installation of all erosion prevention and
sediment control BMPs and a description of the permanent stormwater treatment systems. [Minn. R.
7090]
5.5 The SWPPP must include the location and type of all temporary and permanent erosion prevention and
sediment control BMPs along with procedures used to establish additional temporary BMPs as necessary
for the site conditions during construction. Standard details and/or specifications for BMPs must be
included in the final plans and specifications for the project. [Minn. R. 7090]
5.6 The SWPPP must include the calculations and other information used for the design of temporary
sediment basins and any of the permanent stormwater treatment systems required in Section 15. [Minn.
R. 7090]
5.7 The SWPPP must include estimated quantities anticipated at the start of the project for the life of the
project for all erosion prevention and sediment control BMPs (e.g., linear feet of silt fence or square feet
of erosion control blanket). [Minn. R. 7090]
5.8 The SWPPP must include the number of acres of impervious surface for both pre- and post-construction.
Minn. R. 7090]
5.9 The SWPPP must include a site map with existing and final grades, including drainage area boundaries,
directions of flow and all discharge points where stormwater is leaving the site or entering a surface water.
The site map must indicate the areas of steep slopes. The site map must also include impervious surfaces,
soil types and locations of potential pollutant-generating activities as identified in Section 12. [Minn. R.
7090]
5.10 The SWPPP must include a map of all surface waters, existing wetlands, and stormwater ponds or basins
that can be identified on maps such as United States Geological Survey 7.5 minute quadrangle maps, the
National Wetland Inventory map or equivalent maps and are within one mile (aerial radius measurement)
from the project boundaries that will receive stormwater from the construction site, during or after
construction. The SWPPP must identify if the surface waters are special or impaired waters. [Minn. R.
7090]
5.11 The SWPPP must include a site map showing construction activity areas that are adjacent to and drain to
Public Waters for which the DNR has promulgated "work in water restrictions" during specified fish
spawning time frames. [Minn. R. 7090]
5.12 Permittees must identify locations of 50' buffer zones as required in item 9.17 and 100' permanent buffer
zones as required in item 23.11, on plan sheets in the SWPPP. [Minn. R. 7090]
5.13 If permittees determine compliance with the following requirements is infeasible, they must document the
determination in the SWPPP:
a. temporary sediment basins as described in Section 14; and
b. for linear projects, if the permanent stormwater treatment system cannot be constructed within the
right-of-way, a reasonable attempt must be made to obtain additional right-of-way (item 15.9); and
c. buffer zones as described in item 9.17 and item 23.11. [Minn. R. 7090]
5.14 If permittees determine that a temporary sediment basin is infeasible as described in item 14.10, the
SWPPP must describe the alternative BMPs used. [Minn. R. 7090]
5.15 Where systems cannot meet the full volume reduction requirement on site, (e.g., the site has infiltration
prohibitions, see item 16.14 through item 16.21) the permittee must document the reasons in the SWPPP.
Minn. R. 7090]
5.16 The SWPPP must include any stormwater mitigation measures proposed to be part of the final project in
any environmental review document, endangered species review, archeological or other required local,
state or federal review conducted for the project. For purposes of this permit, mitigation measures means
actions necessary to avoid, minimize, or mitigate for impacts related to erosion prevention, sediment
control, the permanent stormwater treatment system, pollution prevention management measures and
discharges associated with the project's construction activity. [Minn. R. 7090]
5.17 The SWPPP must describe the methods used for permanent cover of all exposed soil areas. [Minn. R. 7090]
5.18 Permittees must identify the locations of areas where construction will be phased to minimize the
duration of exposed soil areas in the SWPPP. [Minn. R. 7090]
5.19 For projects with a discharge point on the project within one (1) mile (aerial radius measurement) of and
which flows to an impaired water, permittees must identify the impaired water(s), and any United States
Environmental Protection Agency (USEPA)-approved Total Maximum Daily Load (TMDL) for the
pollutant(s) or stressor(s) described in item 23.7. Permittees' identification must include those TMDLs
approved at any time prior to permit application submittal and are still in effect. [Minn. R. 7090]
5.20 Permittees must document in the SWPPP, all trained individuals identified in item 21.2. Documentation
must include:
a. names of personnel required to be trained; and
b. dates of training and name of instructor(s) and entity providing training; and
c. content of training course.
If permittees do not know the names of the individuals at the time of application, the permittees must
ensure they document training before construction activity commences. [Minn. R. 7090]
5.21 The SWPPP must identify a person knowledgeable and experienced in the application of erosion
prevention and sediment control BMPs who will coordinate with all contractors, subcontractors, and
operators on-site to oversee the implementation of the SWPPP. [Minn. R. 7090]
5.22 The SWPPP must describe any specific chemicals and chemical treatment systems used for enhancing the
sedimentation process and how it achieves compliance with item 9.18. [Minn. R. 7090]
5.23 The SWPPP must identify the person(s), organizations, or entities responsible for long-term operation and
maintenance of permanent stormwater treatment systems. [Minn. R. 7090]
5.24 The SWPPP must describe methods to minimize soil compaction and preserve topsoil. Minimizing soil
compaction is not required where the function of a specific area dictates compaction. [Minn. R. 7090]
5.25 The SWPPP must include any site assessments for groundwater or soil contamination required in item
16.15. [Minn. R. 7090]
5.26 The SWPPP must account for the following factors in designing temporary erosion prevention and
sediment control BMPs:
a. the expected amount, frequency, intensity, and duration of precipitation; and
b. the nature of stormwater runoff and run-on at the site, including factors such as expected flow from
impervious surfaces, slopes, and site drainage features; and
c. the stormwater volume, velocity, and peak flowrates to minimize discharge of pollutants in
stormwater and to minimize channel and streambank erosion and scour in the immediate vicinity of
discharge points;
and
d. the range of soil particle sizes expected to be present. [Minn. R. 7090]
6.1 SWPPP Amendments. [Minn. R. 7090]
6.2 One of the individuals described in item 21.2.a or item 21.2.b or another qualified individual must
complete all SWPPP changes. Changes involving the use of a less stringent BMP must include a justification
describing how the replacement BMP is effective for the site characteristics. [Minn. R. 7090]
6.3 Permittees must amend the SWPPP to include additional or modified BMPs as necessary to correct
problems identified or address situations whenever there is a change in design, construction, operation,
maintenance, weather or seasonal conditions having a significant effect on the discharge of pollutants to
surface waters or groundwater. [Minn. R. 7090]
6.4 Permittees must amend the SWPPP to include additional or modified BMPs as necessary to correct
problems identified or address situations whenever inspections or investigations by the site owner or
operator, USEPA or MPCA officials indicate the SWPPP is not effective in eliminating or significantly
minimizing the discharge of pollutants to surface waters or groundwater or the discharges are causing
water quality standard exceedances (e.g., nuisance conditions as defined in Minn. R. 7050.0210, subp. 2)
or the SWPPP is not consistent with the objectives of a USEPA approved TMDL. [Minn. R. 7050.0210]
7.1 BMP Selection and Installation. [Minn. R. 7090]
7.2 Permittees must select, install, and maintain the BMPs identified in the SWPPP and in this permit in an
appropriate and functional manner and in accordance with relevant manufacturer specifications and
accepted engineering practices. [Minn. R. 7090]
8.1 Erosion Prevention Practices. [Minn. R. 7090]
8.2 Before work begins, permittees must delineate the location of areas not to be disturbed. [Minn. R. 7090]
8.3 Permittees must minimize the need for disturbance of portions of the project with steep slopes. When
steep slopes must be disturbed, permittees must use techniques such as phasing and stabilization
practices designed for steep slopes (e.g., slope draining and terracing). [Minn. R. 7090]
8.4 Permittees must stabilize all exposed soil areas, including stockpiles. Stabilization must be initiated
immediately to limit soil erosion when construction activity has permanently or temporarily ceased on any
portion of the site and will not resume for a period exceeding 14 calendar days. Stabilization must be
completed no later than 14 calendar days after the construction activity has ceased. Stabilization is not
required on constructed base components of roads, parking lots and similar surfaces. Stabilization is not
required on temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate
stockpiles, demolition concrete stockpiles, sand stockpiles) but permittees must provide sediment controls
at the base of the stockpile. [Minn. R. 7090]
8.5 For Public Waters that the Minnesota DNR has promulgated "work in water restrictions" during specified
fish spawning time frames, permittees must complete stabilization of all exposed soil areas within 200 feet
of the water's edge, and that drain to these waters, within 24 hours during the restriction period. [Minn. R.
7090]
8.6 Permittees must stabilize the normal wetted perimeter of the last 200 linear feet of temporary or
permanent drainage ditches or swales that drain water from the site within 24 hours after connecting to a
surface water or property edge. Permittees must complete stabilization of remaining portions of
temporary or permanent ditches or swales within 14 calendar days after connecting to a surface water or
property edge and construction in that portion of the ditch temporarily or permanently ceases. [Minn. R.
7090]
8.7 Temporary or permanent ditches or swales being used as a sediment containment system during
construction (with properly designed rock-ditch checks, bio rolls, silt dikes, etc.) do not need to be
stabilized. Permittees must stabilize these areas within 24 hours after their use as a sediment containment
system ceases. [Minn. R. 7090]
8.8 Permittees must not use mulch, hydromulch, tackifier, polyacrylamide or similar erosion prevention
practices within any portion of the normal wetted perimeter of a temporary or permanent drainage ditch
or swale section with a continuous slope of greater than 2 percent. [Minn. R. 7090]
8.9 Permittees must provide temporary or permanent energy dissipation at all pipe outlets within 24 hours after
connection to a surface water or permanent stormwater treatment system. [Minn. R. 7090]
8.10 Permittees must not disturb more land (i.e., phasing) than can be effectively inspected and maintained in
accordance with Section 11. [Minn. R. 7090]
9.1 Sediment Control Practices. [Minn. R. 7090]
9.2 Permittees must establish sediment control BMPs on all downgradient perimeters of the site and
downgradient areas of the site that drain to any surface water, including curb and gutter systems.
Permittees must locate sediment control practices upgradient of any buffer zones. Permittees must install
sediment control practices before any upgradient land-disturbing activities begin and must keep the
sediment control practices in place until they establish permanent cover. [Minn. R. 7090]
9.3 If downgradient sediment controls are overloaded, based on frequent failure or excessive maintenance
requirements, permittees must install additional upgradient sediment control practices or redundant
BMPs to eliminate the overloading and amend the SWPPP to identify these additional practices as required
in item 6.3. [Minn. R. 7090]
9.4 Temporary or permanent drainage ditches and sediment basins designed as part of a sediment
containment system (e.g., ditches with rock-check dams) require sediment control practices only as
appropriate for site conditions. [Minn. R. 7090]
9.5 A floating silt curtain placed in the water is not a sediment control BMP to satisfy item 9.2 except when
working on a shoreline or below the waterline. Immediately after the short term construction activity
e.g., installation of rip rap along the shoreline) in that area is complete, permittees must install an upland
perimeter control practice if exposed soils still drain to a surface water. [Minn. R. 7090]
9.6 Permittees must re-install all sediment control practices adjusted or removed to accommodate short-term
activities such as clearing or grubbing, or passage of vehicles, immediately after the short-term activity is
completed. Permittees must re-install sediment control practices before the next precipitation event even
if the short-term activity is not complete. [Minn. R. 7090]
9.7 Permittees must protect all storm drain inlets using appropriate BMPs during construction until they
establish permanent cover on all areas with potential for discharging to the inlet. [Minn. R. 7090]
9.8 Permittees may remove inlet protection for a particular inlet if a specific safety concern (e.g. street
flooding/freezing) is identified by the permittees or the jurisdictional authority (e.g.,
city/county/township/Minnesota Department of Transportation engineer). Permittees must document the
need for removal in the SWPPP. [Minn. R. 7090]
9.9 Permittees must provide silt fence or other effective sediment controls at the base of stockpiles on the
downgradient perimeter. [Minn. R. 7090]
9.10 Permittees must locate stockpiles outside of natural buffers or surface waters, including stormwater
conveyances such as curb and gutter systems unless there is a bypass in place for the stormwater. [Minn.
R. 7090]
9.11 Permittees must install a vehicle tracking BMP to minimize the track out of sediment from the construction
site or onto paved roads within the site. [Minn. R. 7090]
9.12 Permittees must use street sweeping if vehicle tracking BMPs are not adequate to prevent sediment
tracking onto the street. [Minn. R. 7090]
9.13 Permittees must install temporary sediment basins as required in Section 14. [Minn. R. 7090]
9.14 In any areas of the site where final vegetative stabilization will occur, permittees must restrict vehicle and
equipment use to minimize soil compaction. [Minn. R. 7090]
9.15 Permittees must preserve topsoil on the site, unless infeasible. [Minn. R. 7090]
9.16 Permittees must direct discharges from BMPs to vegetated areas unless infeasible. [Minn. R. 7090]
9.17 Permittees must preserve a 50 foot natural buffer or, if a buffer is infeasible on the site, provide redundant
double) perimeter sediment controls when a surface water is located within 50 feet of the project's earth
disturbances and stormwater flows to the surface water. Permittees must install perimeter sediment
controls at least 5 feet apart unless limited by lack of available space. Natural buffers are not required
adjacent to road ditches, judicial ditches, county ditches, stormwater conveyance channels, storm drain
inlets, and sediment basins. If preserving the buffer is infeasible, permittees must document the reasons in
the SWPPP. Sheet piling is a redundant perimeter control if installed in a manner that retains all stormwater.
Minn. R. 7090]
9.18 Permittees must use polymers, flocculants, or other sedimentation treatment chemicals in accordance
with accepted engineering practices, dosing specifications and sediment removal design specifications
provided by the manufacturer or supplier. The permittees must use conventional erosion and sediment
controls prior to chemical addition and must direct treated stormwater to a sediment control system for
filtration or settlement of the floc prior to discharge. [Minn. R. 7090]
10.1 Dewatering and Basin Draining. [Minn. R. 7090]
10.2 Permittees must discharge turbid or sediment-laden waters related to dewatering or basin draining (e.g.,
pumped discharges, trench/ditch cuts for drainage) to a temporary or permanent sediment basin on the
project site unless infeasible. Permittees may dewater to surface waters if they visually check to ensure
adequate treatment has been obtained and nuisance conditions (see Minn. R. 7050.0210, subp. 2) will not
result from the discharge. If permittees cannot discharge the water to a sedimentation basin prior to
entering a surface water, permittees must treat it with appropriate BMPs such that the discharge does not
adversely affect the surface water or downstream properties. [Minn. R. 7050.0210]
10.3 If permittees must discharge water containing oil or grease, they must use an oil-water separator or
suitable filtration device (e.g., cartridge filters, absorbents pads) prior to discharge. [Minn. R. 7090]
10.4 Permittees must discharge all water from dewatering or basin-draining activities in a manner that does not
cause erosion or scour in the immediate vicinity of discharge points or inundation of wetlands in the
immediate vicinity of discharge points that causes significant adverse impact to the wetland. [Minn. R.
7090]
10.5 If permittees use filters with backwash water, they must haul the backwash water away for disposal,
return the backwash water to the beginning of the treatment process, or incorporate the backwash water
into the site in a manner that does not cause erosion. [Minn. R. 7090]
11.1 Inspections and Maintenance. [Minn. R. 7090]
11.2 Permittees must ensure a trained person, as identified in item 21.2.b, will inspect the entire construction
site at least once every seven (7) days during active construction and within 24 hours after a rainfall event
greater than 1/2 inch in 24 hours. [Minn. R. 7090]
11.3 Permittees must inspect and maintain all permanent stormwater treatment BMPs. [Minn. R. 7090]
11.4 Permittees must inspect all erosion prevention and sediment control BMPs and Pollution Prevention
Management Measures to ensure integrity and effectiveness. Permittees must repair, replace or
supplement all nonfunctional BMPs with functional BMPs by the end of the next business day after
discovery unless another time frame is specified in item 11.5 or 11.6. Permittees may take additional time
if field conditions prevent access to the area. [Minn. R. 7090]
11.5 During each inspection, permittees must inspect surface waters, including drainage ditches and
conveyance systems but not curb and gutter systems, for evidence of erosion and sediment deposition.
Permittees must remove all deltas and sediment deposited in surface waters, including drainage ways,
catch basins, and other drainage systems and restabilize the areas where sediment removal results in
exposed soil. Permittees must complete removal and stabilization within seven (7) calendar days of
discovery unless precluded by legal, regulatory, or physical access constraints. Permittees must use all
reasonable efforts to obtain access. If precluded, removal and stabilization must take place within seven
7) days of obtaining access. Permittees are responsible for contacting all local, regional, state and federal
authorities and receiving any applicable permits, prior to conducting any work in surface waters. [Minn. R.
7090]
11.6 Permittees must inspect construction site vehicle exit locations, streets and curb and gutter systems within
and adjacent to the project for sedimentation from erosion or tracked sediment from vehicles. Permittees
must remove sediment from all paved surfaces within one (1) calendar day of discovery or, if applicable,
within a shorter time to avoid a safety hazard to users of public streets. [Minn. R. 7090]
11.7 Permittees must repair, replace or supplement all perimeter control devices when they become
nonfunctional or the sediment reaches 1/2 of the height of the device. [Minn. R. 7090]
11.8 Permittees must drain temporary and permanent sedimentation basins and remove the sediment when
the depth of sediment collected in the basin reaches 1/2 the storage volume. [Minn. R. 7090]
11.9 Permittees must ensure that at least one individual present on the site (or available to the project site in three (3)
calendar days) is trained in the job duties described in item 21.2.b. [Minn. R. 7090]
11.10 Permittees may adjust the inspection schedule described in item 11.2 as follows:
a. inspections of areas with permanent cover can be reduced to once per month, even if construction
activity continues on other portions of the site; or
b. where sites have permanent cover on all exposed soil and no construction activity is occurring anywhere
on the site, inspections can be reduced to once per month and, after 12 months, may be suspended
completely until construction activity resumes. The MPCA may require inspections to resume if conditions
warrant; or
c. where construction activity has been suspended due to frozen ground conditions, inspections may be
suspended. Inspections must resume within 24 hours of runoff occurring, or upon resuming construction,
whichever comes first. [Minn. R. 7090]
11.11 Permittees must record all inspections and maintenance activities within 24 hours of being conducted and
these records must be retained with the SWPPP. These records must include:
a. date and time of inspections; and
b. name of persons conducting inspections; and
c. accurate findings of inspections, including the specific location where corrective actions are needed; and
d. corrective actions taken (including dates, times, and party completing maintenance activities); and
e. date of all rainfall events greater than 1/2 inches in 24 hours, and the amount of rainfall for each event.
Permittees must obtain rainfall amounts by either a properly maintained rain gauge installed onsite, a
weather station that is within one (1) mile of your location, or a weather reporting system that provides
site specific rainfall data from radar summaries; and
f. if permittees observe a discharge during the inspection, they must record and should photograph and
describe the location of the discharge (i.e., color, odor, settled or suspended solids, oil sheen, and other
obvious indicators of pollutants); and
g. any amendments to the SWPPP proposed as a result of the inspection must be documented as required
in Section 6 within seven (7) calendar days. [Minn. R. 7090]
12.1 Pollution Prevention Management Measures. [Minn. R. 7090]
12.2 Permittees must place building products and landscape materials under cover (e.g., plastic sheeting or
temporary roofs) or protect them by similarly effective means designed to minimize contact with
stormwater. Permittees are not required to cover or protect products which are either not a source of
contamination to stormwater or are designed to be exposed to stormwater. [Minn. R. 7090]
12.3 Permittees must place pesticides, fertilizers and treatment chemicals under cover (e.g., plastic sheeting or
temporary roofs) or protect them by similarly effective means designed to minimize contact with
stormwater. [Minn. R. 7090]
12.4 Permittees must store hazardous materials and toxic waste, (including oil, diesel fuel, gasoline, hydraulic
fluids, paint solvents, petroleum-based products, wood preservatives, additives, curing compounds, and
acids) in sealed containers to prevent spills, leaks or other discharge. Storage and disposal of hazardous
waste materials must be in compliance with Minn. R. ch. 7045 including secondary containment as
applicable. [Minn. R. 7090]
12.5 Permittees must properly store, collect and dispose solid waste in compliance with Minn. R. ch. 7035.
Minn. R. 7035]
12.6 Permittees must position portable toilets so they are secure and will not tip or be knocked over.
Permittees must properly dispose sanitary waste in accordance with Minn. R. ch. 7041. [Minn. R. 7041]
12.7 Permittees must take reasonable steps to prevent the discharge of spilled or leaked chemicals, including
fuel, from any area where chemicals or fuel will be loaded or unloaded including the use of drip pans or
absorbents unless infeasible. Permittees must ensure adequate supplies are available at all times to clean
up discharged materials and that an appropriate disposal method is available for recovered spilled
materials. Permittees must report and clean up spills immediately as required by Minn. Stat. 115.061,
using dry clean up measures where possible. [Minn. Stat. 115.061]
12.8 Permittees must limit vehicle exterior washing and equipment to a defined area of the site. Permittees
must contain runoff from the washing area in a sediment basin or other similarly effective controls and must
dispose waste from the washing activity properly. Permittees must properly use and store soaps,
detergents, or solvents. [Minn. R. 7090]
12.9 Permittees must provide effective containment for all liquid and solid wastes generated by washout
operations (e.g., concrete, stucco, paint, form release oils, curing compounds and other construction
materials) related to the construction activity. Permittees must prevent liquid and solid washout wastes
from contacting the ground and must design the containment so it does not result in runoff from the
washout operations or areas. Permittees must properly dispose liquid and solid wastes in compliance with
MPCA rules. Permittees must install a sign indicating the location of the washout facility. [Minn. R. 7035,
Minn. R. 7090]
13.1 Permit Termination Conditions. [Minn. R. 7090]
13.2 Permittees must complete all construction activity and must install permanent cover over all areas prior to
submitting the NOT. Vegetative cover must consist of a uniform perennial vegetation with a density of 70
percent of its expected final growth. Vegetation is not required where the function of a specific area
dictates no vegetation, such as impervious surfaces or the base of a sand filter. [Minn. R. 7090]
13.3 Permittees must clean the permanent stormwater treatment system of any accumulated sediment and
must ensure the system meets all applicable requirements in Section 15 through 19 and is operating as
designed. [Minn. R. 7090]
13.4 Permittees must remove all sediment from conveyance systems prior to submitting the NOT. [Minn. R.
7090]
13.5 Permittees must remove all temporary synthetic erosion prevention and sediment control BMPs prior to
submitting the NOT. Permittees may leave BMPs designed to decompose on-site in place. [Minn. R. 7090]
13.6 For residential construction only, permit coverage terminates on individual lots if the structures are
finished and temporary erosion prevention and downgradient perimeter control is complete, the
residence sells to the homeowner, and the permittee distributes the MPCA's "Homeowner Fact Sheet" to
the homeowner. [Minn. R. 7090]
13.7 For construction projects on agricultural land (e.g., pipelines across cropland), permittees must return the
disturbed land to its preconstruction agricultural use prior to submitting the NOT. [Minn. R. 7090]
14.1 Temporary Sediment Basins. [Minn. R. 7090]
14.2 Where ten (10) or more acres of disturbed soil drain to a common location, permittees must provide a
temporary sediment basin to provide treatment of the runoff before it leaves the construction site or
enters surface waters. Permittees may convert a temporary sediment basin to a permanent basin after
construction is complete. The temporary basin is no longer required when permanent cover has reduced
the acreage of disturbed soil to less than ten (10) acres draining to a common location. [Minn. R. 7090]
14.3 The temporary basin must provide live storage for a calculated volume of runoff from a two (2)-year, 24-
hour storm from each acre drained to the basin or 1,800 cubic feet of live storage per acre drained,
whichever is greater. [Minn. R. 7090]
14.4 Where permittees have not calculated the two (2)-year, 24-hour storm runoff amount, the temporary
basin must provide 3,600 cubic feet of live storage per acre of the basins' drainage area. [Minn. R. 7090]
14.5 Permittees must design basin outlets to prevent short-circuiting and the discharge of floating debris.
Minn. R. 7090]
14.6 Permittees must design the outlet structure to withdraw water from the surface to minimize the discharge
of pollutants. Permittees may temporarily suspend the use of a surface withdrawal mechanism during
frozen conditions. The basin must include a stabilized emergency overflow to prevent failure of pond
integrity. [Minn. R. 7090]
14.7 Permittees must provide energy dissipation for the basin outlet within 24 hours after connection to a
surface water. [Minn. R. 7090]
14.8 Permittees must locate temporary basins outside of surface waters and any buffer zone required in item
23.11. [Minn. R. 7090]
14.9 Permittees must construct the temporary basins prior to disturbing 10 or more acres of soil draining to a
common location. [Minn. R. 7090]
14.10 Where a temporary sediment basin meeting the requirements of item 14.3 through 14.9 is infeasible, permittees
must install effective sediment controls such as smaller sediment basins and/or sediment traps,
silt fences, vegetative buffer strips or any appropriate combination of measures as dictated by individual
site conditions. In determining whether installing a sediment basin is infeasible, permittees must consider
public safety and may consider factors such as site soils, slope, and available area on-site. Permittees must
document this determination of infeasibility in the SWPPP. [Minn. R. 7090]
15.1 Permanent Stormwater Treatment System. [Minn. R. 7090]
15.2 Permittees must design the project so all stormwater discharged from the project during and after
construction activities does not cause a violation of state water quality standards, including nuisance
conditions, erosion in receiving channels or on downslope properties, or a significant adverse impact to
wetlands caused by inundation or decrease of flow. [Minn. R. 7090]
15.3 Permittees must design and construct a permanent stormwater treatment system to treat the water
quality volume if the project's ultimate development replaces vegetation and/or other pervious surfaces
creating a net increase of one (1) or more acres of cumulative impervious surface. [Minn. R. 7090]
15.4 Permittees must calculate the water quality volume as one (1) inch times the net increase of impervious
surfaces created by the project. [Minn. R. 7090]
15.5 Permittees must first consider volume reduction practices on-site (e.g., infiltration or other) when
designing the permanent stormwater treatment system. If this permit prohibits infiltration as described in
item 16.14 through item 16.21, permittees may consider a wet sedimentation basin, filtration basin or
regional pond. This permit does not consider wet sedimentation basins and filtration systems to be volume
reduction practices. [Minn. R. 7090]
15.6 For projects where the full volume reduction requirement cannot be met on-site, (e.g., the site has
infiltration prohibitions), permittees must document the reasons in the SWPPP. [Minn. R. 7090]
15.7 Permittees must discharge the water quality volume to a permanent stormwater treatment system prior
to discharge to a surface water. For purposes of this item, surface waters do not include man-made
drainage systems that convey stormwater to a permanent stormwater treatment system. [Minn. R. 7090]
15.8 Where the proximity to bedrock precludes the installation of any of the permanent stormwater treatment
practices required by Sections 15 through 19, permittees must install other treatment such as grassed
swales, smaller ponds, or grit chambers, prior to the discharge of stormwater to surface waters. [Minn. R.
7090]
15.9 For linear projects where permittees cannot treat the entire water quality volume within the existing rightof-way,
permittees must make a reasonable attempt to obtain additional right-of-way, easement or other
permission for stormwater treatment during the project planning process. Documentation of these
attempts must be in the SWPPP. Permittees must still consider volume reduction practices first as
described in item 15.5. If permittees cannot obtain additional right-of-way, easement or other permission,
they must maximize the treatment of the water quality volume prior to discharge to surface waters.
Minn. R. 7090]
16.1 Infiltration Systems. [Minn. R. 7090]
16.2 Infiltration options include, but are not limited to: infiltration basins, infiltration trenches, rainwater
gardens, bioretention areas without underdrains, swales with impermeable check dams, and natural
depressions. If permittees utilize an infiltration system to meet the requirements of this permit, they must
incorporate the design parameters in item 16.3 through item 16.21. Permittees must follow the infiltration
prohibition in item 16.14 anytime an infiltration system is designed, including those not required by this
permit. [Minn. R. 7090]
16.3 Permittees must design infiltration systems such that pre-existing hydrologic conditions of wetlands in the
vicinity are not impacted (e.g., inundation or breaching a perched water table supporting a wetland).
Minn. R. 7090]
16.4 Permittees must not excavate infiltration systems to final grade, or within three (3) feet of final grade, until
the contributing drainage area has been constructed and fully stabilized unless they provide rigorous
erosion prevention and sediment controls (e.g., diversion berms) to keep sediment and runoff completely
away from the infiltration area. [Minn. R. 7090]
16.5 When excavating an infiltration system to within three (3) feet of final grade, permittees must stake off
and mark the area so heavy construction vehicles or equipment do not compact the soil in the infiltration area.
Minn. R. 7090]
16.6 Permittees must use a pretreatment device such as a vegetated filter strip, forebay, or water quality inlet
e.g., grit chamber) to remove solids, floating materials, and oil and grease from the runoff, to the
maximum extent practicable, before the system routes stormwater to the infiltration system. [Minn. R.
7090]
16.7 Permittees must design infiltration systems to provide a water quality volume (calculated as an
instantaneous volume) of one (1) inch of runoff, or one (1) inch minus the volume of stormwater treated
by another system on the site, from the net increase of impervious surfaces created by the project. [Minn.
R. 7090]
16.8 Permittees must design the infiltration system to discharge all stormwater (including stormwater in excess
of the water quality volume) routed to the system through the uppermost soil surface or engineered
media surface within 48 hours. Permittees must route additional flows that cannot infiltrate within 48
hours to bypass the system through a stabilized discharge point. [Minn. R. 7090]
16.9 Permittees must provide a means to visually verify the infiltration system is discharging through the soil
surface or filter media surface within 48 hours or less. [Minn. R. 7090]
16.10 Permittees must provide at least one soil boring, test pit or infiltrometer test in the location of the
infiltration practice for determining infiltration rates. [Minn. R. 7090]
16.11 For design purposes, permittees must divide field measured infiltration rates by 2 as a safety factor or
permittees can use soil-boring results with the infiltration rate chart in the Minnesota Stormwater Manual
to determine design infiltration rates. When soil borings indicate type A soils, permittees should perform
field measurements to verify the rate is not above 8.3 inches per hour. This permit prohibits infiltration if
the field measured infiltration rate is above 8.3 inches per hour. [Minn. R. 7090]
16.12 Permittees must employ appropriate on-site testing ensure a minimum of three (3) feet of separation from

mitigative sequence has been followed in accordance with items 22.3 or 22.4. [Minn. R. 7050.0186]
22.3 If the potential adverse impacts to a wetland on a specific project site are addressed by permits or other
approvals from an official statewide program (U.S. Army Corps of Engineers 404 program, Minnesota Department of
Natural Resources, or the State of Minnesota Wetland Conservation Act) that are issued
specifically for the project and project site, permittees may use the permit or other determination issued
by these agencies to show the potential adverse impacts are addressed. For purposes of this permit,
deminimus actions are determinations by the permitting agency that address the project impacts, whereas
a non-jurisdictional determination does not address project impacts. [Minn. R. 7090]
22.4 If there are impacts from the project not addressed in one of the permits or other determinations
discussed in item 22.3 (e.g., permanent inundation or flooding of the wetland, significant degradation of
water quality, excavation, filling, draining), permittees must minimize all adverse impacts to wetlands by
utilizing appropriate measures. Permittees must use measures based on the nature of the wetland, its
vegetative community types and the established hydrology. These measures include in order of
preference:
a. avoid all significant adverse impacts to wetlands from the project and post-project discharge;
b. minimize any unavoidable impacts from the project and post-project discharge;
c. provide compensatory mitigation when the permittees determine(s) that there is no reasonable and
practicable alternative to having a significant adverse impact on a wetland. For compensatory mitigation,
wetland restoration or creation must be of the same type, size and whenever reasonable and practicable
in the same watershed as the impacted wetland. [Minn. R. 7050.0186]

The RSI site is located at the northeast corner of Flying Cloud Drive and Great Plains Blvd. The
existing site was previously constructed with a building and parking lot for an animal daycare and
overnight facility.
The site has both hydrologic soil groups B and C on-site. The predominate soil group for the site
is hydrologic group C. The site drains from north to south and drains to the Flying Cloud Drive ditch
along the north side of the road and eventually drains to across the road and to Rice Lake. The site
ranges in elevation from 798 on the north side to 726 on the south side.
The site is being proposed to be developed into four (4) buildings of 20,000 square feet each
wlth an access off of Flying Cloud Drive in the southeast corner of the property. The proposed
development will collect storm water from the building and drive and direct the stormwater into a
stormwater pond in the southwest corner of the property through an on-site storm sewer system. The
proposed site has been modeled using HydroCAD with Atlas 14 stormwater events for the 1,2,10 and
100-year events. The proposed and existing stormwater run-off rates for the site are as follows:
EXISTING PROPOSED

1OO YEAR 45.21 c.f.s.18.76 c.f.s
The Infiltration for the site wlll be provided with a filtration pond adjacent to the stormwater
pond. The proposed site will have 2.79 acj,es ot 72!,532 square feet of impervlous surface. The
impervious surface is required to infiltrate the first one inch of stormwater runoff. The proposed
infiltration required is 121,532 sq ft x 1 inch/12inch or 10,128 cubic feet. The infiltration volume
provided is 10,220 cubic feet.
The proposed stormwater plan meets the city stormwater requirements. We have attached the
HydrocAD model for your review. lf you have any questions, please call.

Re: 10500 and 10520 Great Plains Boulevard Conceptual PUD Review –
Planning Case No. 2022-04
EASEMENTS
The preliminary plat provided with the Conceptual PUD materials, dated 12/4/2018 and
produced by James R. Hill, Inc., illustrates typical 10 foot public drainage and utility easements
DUE) along all property lines. Additional public DUEs will be required over public utilities
only watermain at this phase) extended into the property as discussed under the “Sanitary Sewer
and Watermain” section of this report. The dimensions of the DUE must be adequate to
properly repair and maintain the utility; the minimum for watermains is typically 20 feet wide,
centered over the main, due to their typical installation depth of 7.5 feet, however additional
DUE may be required depending on the plans that will be provided.
Any and all existing easements must be vacated prior to recording of the final plat.
Based on Carver County property information there appears to be two parcels abutting the
preliminary plat’s western property lines that are listed as “Parcel ID: Gap”. It is unclear if these
parcels are being considered in the lot combination of the Conceptual PUD, or if they are being
considered a part of the adjacent lot to the west (PID #250361300). Clarification regarding the
status of “Parcel ID: Gap” in conjunction with the proposed plat will be required prior to
recording of the final plat from either the County or the applicant.
224
The preliminary plat abuts and gains access from Carver County right-of-way. Thus, the
applicant must coordinate with Carver County regarding any additional considerations and
potential conditions associated with easements for the property as well as any requirements
associated with ingress/egress and construction activities such as during grading and hauling
operations.
EXISTING CONDITIONS SURVEY
The existing condition survey, dated 1/28/2022 and produced by James R. Hill, Inc., will need to
be updated upon resubmittal to incorporate the following information, as necessary:
Topographic data 100 feet beyond the property boundary
Illustration of existing features that would impact the site’s ingress/egress (e.g. the full
extents of Flying Cloud Drive which includes the median near the site’s entrance)
Utilities on or adjacent to the property, including location, size and invert elevation of
storm sewers, catch basins and manholes; location and size of water mains (including
casings) and hydrants; location of gas mains, high pressure lines, fire hydrants, electric
and telephone lines, and street lights. The direction, distance to, and size of such
facilities shall be indicated.
Wetlands
Bluff impact zones
Sewage treatment systems and associated conveyance systems
Existing easements and associated recording document numbers
Property information within 150 feet of the property’s boundary
Retaining wall elevations
WETLANDS
A study completed by Kjolhaug Environmental Services in 2021 shows there are no wetlands
within the project site. City records show there is one wetland just south of the project site located in
the drainage ditch along County Road 101 (Great Plains Blvd). This wetland has been classified as
a manage type 2 wetland in the City’s Surface Water Management Plan. A 1992 delineation report
indicates the source of water as surface water runoff and the route of outflow is a culvert to the
Minnesota River.
The preliminary plans submitted with the Conceptual PUD show grading in close proximity to
the wetland which is near the proposed access to the site. Article VI, Chapter 20 of City Code
describes buffer strip and setback requirements. For example a 10 to 30 foot buffer strip with an
average of 20 foot width for manage type 2 wetlands. There is also a 30-foot setback from the
buffer strip so the building setback should be from 40 to 60 feet averaging 50 feet away from the
225
edge of a manage type 2 wetland. The wetland buffer and wetland setback should be shown on the
grading plan and stacked in the field prior to construction. The preliminary plans appear meet the
wetland buffer and setback requirements.
BLUFFS
There is a steep slope located on the west side of the property; the bottom generally follows the
750 contour of the property and the top of the follows the 772 -774 contours. The steep area is
called out in the preliminary plans as a bluff, however because this area was created from
grading completed as part of a development project in 1996 it is not a natural slope and therefore
does not meet the City's definition of a bluff. The Lower Minnesota River Watershed District
LMRWD) also regulates steep slopes within their jurisdiction. The applicant will need to
coordinate with the watershed district to confirm if the project triggers any regulations as defined
in Rule F – Steep Slopes.
RETAINING WALLS
Preliminary plans provided with the Conceptual PUD submittal indicate that retaining walls may
be required for the development. These walls are shown around the northern and western
portions of the property. Portions of the retaining walls illustrated are shown to be located
within public drainage and utility easements along the western property lines. An encroachment
agreement would be required for any retaining walls located within public easements.
Portions of the retaining walls are illustrated to be either close to or directly over the western
property line. Due to the proximity to the property line, the construction of these walls would
require construction activities to occur on the abutting property. The construction of any
improvements that impact or require access to abutting properties must have the appropriate
right-of-entry agreements and/or temporary construction easements prior to construction
operations commencing.
Retaining walls over 4 feet in height shall be constructed in accordance with plans prepared by a
registered engineer and shall be constructed of a durable material (smooth face concrete,
masonry/mortared, railroad ties and timber are prohibited). It should be noted that the height of
any retaining wall is measured from the top of the wall to the bottom of the footing (not to the
top of grade adjacent to the bottom of the wall).
ACCESS
Access to the site is currently had from Flying Cloud Drive (CSAH 61) and is located near the
western property line. The preliminary plans indicate that the current access will remain and no
226
additional accesses to the surrounding Carver County rights-of-way are proposed. The
development will be required to construct a commercial driveway access in accordance with City
Standards. Any comments or conditions by Carver County associated with impacts to their
rights-of-way must be adhered to and all permits required must be obtained prior to construction
activities commencing.
It appears no turnaround is provided in the preliminary plans. In accordance with Section 20-
1122 of City Code a turnaround is required when access is had from a state highway, county road
or collector roadway. As access is being had from CSAH 61 a turnaround will be required that
can adequately facilitate the turning movement of the largest anticipated design vehicle for the
site or the City’s largest fire truck, whichever is greater.
GRADING AND DRAINAGE
The existing conditions plansheet and drainage maps included in the Conceptual PUD submittal
show an existing building near the center of the property with access to Great Plains Boulevard
provide by an asphalt parking area and gravel driveway. Stormwater runoff general flows from
north to south down the slope of the site where it enters a drainage swale along Flying Cloud
Drive. The drainage swale conveys stormwater from west to east. Stormwater leaves the site by
way of an existing 48” culvert under Flying Cloud Drive which conveys the stormwater to the
South through Bluff Creek and ultimately outleting to the Minnesota River.
The preliminary plans provided with the Conceptual PUD submittal show a significant amount
of grading. The design steepens the hill on the northeast side of the site to create a flat area
conducive for the four proposed buildings with access and parking. The proposed design uses
combination of drainage swales and stormwater infrastructure to collect and convey stormwater
into a Best Management Practice (BMP) located on the southwest corner of the property. The
design shows stormwater being conveyed from the proposed BMP to the existing swale along
Flying Cloud Blvd through an outlet control structure. Any impacts to Carver County’s right-of-
way must be approved and permitted by the County prior to construction activities. The overall
design of the stormwater infrastructure mimics the flow path of the existing condition and acts to
convey stormwater runoff from impervious surfaces through water quality BMPS. A more
detailed analysis of stormwater volumes and rates may be required to show the wetland onsite is
not negatively impacted by the proposed design.
EROSION PREVENTION AND SEDIMENT CONTROL
227
The proposed development will exceed one (1) acre of disturbance and will, therefore, be subject
to the General Permit Authorization to Discharge Stormwater Associated with Construction
Activity Under the National Pollution Discharge Elimination/State Disposal System (NPDES
Construction Permit). The applicant has prepared and submitted a preliminary Surface Water
Pollution Prevention Plan (SWPPP) and generally appears feasible. The SWPPP is a required
submittal element for preliminary plat review. No earth disturbing activities may occur until an
approved SWPPP is developed. This SWPPP shall be a standalone document consistent with the
NPDES Construction Permit and shall contain all required elements as listed in Parts III and IV
of the permit. The SWPPP will need to be updated as the plans are finalized, when the
contractor and their sub-contractors are identified and as other conditions change.
SANITARY SEWER AND WATERMAIN
Currently, municipal sanitary sewer and potable water services are not available to the site.
During the build-out of the Highway 101 Realignment project, which was substantially
completed in 2021, public sanitary sewer mains and water mains were extended along the
corridor. However, these newly extended utilities are not fully active nor ready for operation to
service properties, as such the site does not have adequate public sanitary and water to fully
serve the development’s needs.
In 2014, a Highway 61 corridor study was conducted in response to several near and long-term
infrastructure projects at the time (e.g. Highway 101 Realignment, CSAH 61 reconstruction,
flood mitigation projects, etc.) which prompted the City to investigate the feasibility of extending
public utilities to the southern portion of the City. The study, known as “County Road 61
Corridor Plan”, conducted by SRF in association with Hoisington Koegler Group, Inc.,
determined that utility extensions were feasible within the study area. The image below, taken
from Figure 3.1 of the City’s 2040 Comprehensive Plan, depicts the City’s existing and planned
sanitary sewer in this area (planned water system build-out generally adheres to the same areas
and alignments).
228
The proposed development falls within the southcentral region of sanitary subdistrict LB-1 (the
Lower Bluff Creek District). The 2014 study estimated costs and fee revenue associated with
extending City utilities to the study area, along with estimated utility assessments per acre, which
are shown in Tables 1 and 2.
229
With a lack of adequate city utilities in the area, the development will be required to provide
private utility services (sanitary sewer and potable water) to adequately meet the needs of the
development. The City has preliminarily agreed to allow the development to tap into the public
watermain which was extended with the Highway 101 Realignment project, but only to service
the development’s fire suppression needs. At this time there is not sufficient demand along the
extended watermain to supply water to the quality standards that the City requires for
consumption. This is important to note because the preliminary plans provided indicate the
existing well on-site is proposed to be abandoned. If the site will have any fixtures requiring the
use of water other than for fire suppression needs, a private source of water supply must be used
for those fixtures.
The preliminary plans indicate tapping of the existing public watermain for fire suppression
needs at the southwest corner of the property. As shown on the preliminary plans this would be
infeasible as the watermain was housed in a casing at the location, and would be required to be
extended further west to facilitate the connection. Regardless, the development will be required
to extend the public watermain to the western property line, and the extension into the site must
be along or near the improved private access to allow for reasonable access for future repair and
maintenance. Adequate public drainage and utility easements will be required over the public
main as it extends into the site. Private fire laterals can then be tapped from the public main as
necessary.
The property and potential future properties associated with this developable area will be
specially assessed for the extension of the public sanitary sewer when they connect.
STORM WATER MANAGEMENT
The project site is located within the Lower Minnesota River Watershed District (LMRWD). The
LMRWD is the LGU that administers NPDES Construction Permits for stormwater
management. The proposed development will exceed the one (1) acre of new impervious area
and will therefore require permanent stormwater BMPs to be constructed as part of this project
230
and maintained by the owner. The project will be subject to stormwater regulations outlined
under LMRWD Rule D including rate, volume, and water quality.
The City of Chanhassen also regulates the design, construction, and maintenance of stormwater
infrastructure. Article VII, Chapter 19 of City Code describes the required storm water
management development standards. Section 19-141 states that “these development standards
shall be reflected in plans prepared by developers and/or project proposers in the design and
layout of site plans, subdivisions and water management features.” A stormwater maintenance
agreement and associated operations and maintenance plan is required for all private stormwater
BMPs.
Preliminary plans provided with the Conceptual PUD submittal show stormwater treatment and
rate control from a wet pond with an incorporated filtration bench BMP located on the southwest
corner of the property. The stormwater BMP appears to be properly sized for the impervious
surface proposed in the plans. The design of the BMP is highly dependent on soil types and
infiltration rates of the underlying soils. Soil borings, infiltration testing and an associated
geotechnical report will be needed to confirm the design of the stormwater BMP. No
geotechnical report was included as part of the Conceptual PUD submittal.
The City’s water resources engineer reviewed the preliminary plans provided with the
Conceptual PUD. Specific comments regarding the design of stormwater infrastructure and
BMPs were provided to the applicant.
STORM WATER MANAGEMENT FEES
In 2005 a Stipulation of Settlement (Court File No. 10-CV-05-48) between PCH Development,
LLC and the City of Chanhassen was agreed to regarding the park dedication fees and surface
water management fees surrounding the subdivision of the “Paws Claws and Hooves Addition”
subdivision (PC #2003-04 and the property of this Conceptual PUD). The surface water
management fee was reduced to $9,900.00 and was paid on 7/25/2005. The settlement
agreement states, “If all or any part of the property is changed to a different principal use or
further subdivided, the property shall be subject to payment of additional park dedication and
surface water management fees based upon the rates in effect at that time applicable to the
proposed use and type of municipal approval requested.” However, as the stipulation was
between the property owner and the City and was not required to be memorialized against the
property, if the property owner changes from PCH Development, LLC no stormwater fees will
be required if the PUD is approved. If the property is subdivided in the future, stormwater fees
will be collected at the rate in affect at the time of platting, minus the $9,900.00 already paid.

Re: Development / Access Review Comments: 10500 and 10520 Great Plains Boulevard
Conceptual Planned Unit Development (PUD) located at PID#s 256010010 and 256010020
adjacent to County State Aid Highway (CSAH) 101 (Great Plains Blvd.) and CSAH 61 (Flying
Cloud Dr.)
Thank you for the opportunity to review the subject development in the City of Chanhassen. Consistent
with the County Comprehensive Plan and County Codes, and other official controls of the County, the
following are comments and recommended conditions of approval and as potential requirements for any
necessary permits to be issued for the project.
1. Regarding access to the County highway
a. The proposed driveway access onto CSAH 61 was built with the County’s Flying Cloud Dr.
project and the proposed driveway location appears consistent with the access that was
constructed.
b. Provide an estimate of the maximum number of vehicles that may make a left turn into the
site during an hour to evaluate the potential operational and safety risk of vehicles and any
towed trailers obstructing eastbound CSAH 61 traffic. Additional improvements may be
needed to mitigate any operational or safety risks that are identified.
2. Regarding County highway right of way
a. The property boundaries shall match the existing County highway right of way. The
proposed boundary appears to match the highway right of way as modified by CR RW Plat
No. 29.
3. Regarding grading adjacent to the County highway
a. County requests drainage calculations and data for the proposed development. Revision is
likely needed regarding the outlet for the proposed stormwater treatment ponds, which is
not in a good location due to the flow outlet being up gradient from the trail which is
below. Drainage should be carried and directed further to the east into the roadside ditch
that currently exists instead of to the west side of the development on the steep slopes and
directly pointed at the trail embankment.
b. Confirm the proposed drainage will not create an adverse impact to the County right of
way.
c. Proposed grading shall tie-in and be compatible with the existing ground in the County
232
right of way.
4. Regarding final approvals and required permits -
a. The County will need to review and approve the final grading plans for properties adjacent
to CSAH 101 and CSAH 61. A grading permit will be required for grading work within the
highway right of way.
b. An access permit will be required for access to CSAH 61 due to this change in use and
connection of the site improvements to CSAH 61.
c. The technical details of any final plat, its boundaries and form(s) will need to be reviewed
and approved by the County Surveyor.
d. Prior to any work affecting or on County highways or in County right of way, the applicant
shall coordinate plans with the County Engineer and obtain a Utility, Access, or
Excavating/Filling/Grading Permit(s) from Carver County Public Works:
www.co.carver.mn.us/departments/public-works/quick-links/permits). Final details of
locations, grades, and profiles affecting County roads as well as any utility connections will
need to be reviewed and approved prior to any permits.
e. Any damages, modifications, or changes incurred on County highways from current or
approved conditions will need to remedied or updated at development expense, including
costs incurred by the County.
These are the County’s comments at this time. If you have any questions or need further assistance, please
contact staff noted below:

Landscaping and Tree Preservation
10500/10520 Great Plains Blvd
A Planned Unit Development (PUD) is expected to ‘protect.. mature trees…” and ‘reflect higher quality
design of…landscaping’. The proposed development site has existing trees as evidenced in a field
inspection and shown in current aerial mapping applications. The existing trees and woods are not
included on the Existing Conditions sheets, nor reflected in the submitted Canopy Coverage calculations
shown on the Landscape Plan. It is unknown if any of the existing trees will be preserved, but it appears
that there may be some in part of the ‘undisturbed area’ shown on the plan that may possibly be
unaffected by site grading. The applicant will need to submit a tree inventory for the site as well as
update the canopy coverage calculations. Based on the calculations, the applicant will need to meet and
potentially exceed the minimum requirements for replacement tree planting on the site. Staff
recommends that the applicant consider using a no-mow turf grass or prairie mix in place of the
proposed sod areas to promote a sustainable landscape design for the site.
A site plan review for the site will be required to show foundation plantings on the outward facing sides
of the buildings. Bufferyard plantings are required along the property lines. The landscape plan shows
the following proposed landscaping for the site.

The applicant does not meet minimum requirements for bufferyard plantings on the site.
234
The vehicular use area is required by code to have landscaping that includes islands or peninsulas for
every 6,000 sq. ft. of use area and landscape areas and a minimum number of trees in and around the
parking area in order to reduce the overall heat island effect of pavement and improve aesthetics of the
site. Minimum requirements for landscaping for the parking lot include 2,816 sq. ft. of landscaped area
around the parking lot, 5 landscape islands or peninsulas, and 11 trees for the parking lot. The
applicant’s proposed as compared to the requirements for landscape area and parking lot trees is shown
in the following table.
Required Proposed

area
2,816 sq. ft.0 sq. ft.
Trees/parking lot 11 trees 0 trees
Landscape islands or

5 islands/peninsulas 0 islands/peninsulas
The landscaping as proposed in the concept plan does not meet minimum requirements for trees,
landscaping or islands/peninsulas. Acknowledging that the standard requirements for trees and
landscape islands within the paved area may prove difficult to incorporate into the site, staff
recommends that the applicant propose alternatives that also provide environmental benefits and/or
reduction in the heat island effect caused by large expanses of asphalt.

CHANHASSEN PLANNING COMMISSION
REGULAR MEETING
MINUTES
FEBRUARY 15, 2022
CALL TO ORDER:
Chairman von Oven called the meeting to order at 7:00 p.m.
MEMBERS PRESENT: Laura Skistad, Eric Noyes, Mark von Oven, Erik Johnson, and Kelsey
Alto.
MEMBERS ABSENT: Doug Reeder, Steven Weick.
STAFF PRESENT: Kate Aanenson, Community Development Director; MacKenzie Young-
Walters, Associate Planner
PUBLIC PRESENT:
Grant Dattilo 3703 South Cedar Drive (on behalf of the applicant)
Chairman von Oven reviewed guidelines for conducting the Planning Commission meeting.
PUBLIC HEARING:
3703 SOUTH CEDAR DRIVE VARIANCE
Associate Planner Young-Walters presented the staff report on this item, noting this first
appeared before the Planning Commission in November. At the time it was tabled, the Applicant
and staff have worked together to address some of the Commissioner’s comments. The variance
is for front yard, side yard, and shoreland setbacks, and lot cover maximum for construction of a
single-family house located at 3703 South Cedar Drive. The Applicant is proposing to demolish
an existing cabin and build a single-family home on a substandard lot. In November, the
Applicant expressed concern with a staff condition to create a 20-foot wide vegetative buffer
across the width of the parcel, noting that there is a beach area and a very small side yard. The
Planning Commission directed staff and the Applicant to work together to develop a compromise
addressing the City’s concern on the impact to the lake’s water quality while preserving as much
of the Applicant’s beach as possible. Working with the Water Resources Engineer, they
developed a solution that meets the minimum intent of the surface water management plan and
gives the Applicant as much use of the yard space as possible. Mr. Young-Walters showed the
proposed plan on screen with the 400-square foot buffer with a French drain system for runoff.
Grant Dattilo, son of the Applicants, noted his parents were unable to attend the meeting and
asked him to tell the Commissioners that they agree with what the City is proposing and thanks
the City Staff for working with them to make it happen.
Chairman von Oven opened the public hearing.

Planning Commission Minutes – February 15, 2022

Chairman von Oven closed the public hearing.
Commissioner Noyes moved, Commissioner Skistad seconded that the Chanhassen Board
of appeals and adjustments approves 34.2-foot shoreland setback, 3-foot east and west side
yard setback, 1.3-foot front yard setback, and 19 percent lot cover variances, subject to the
Conditions of Approval, and adopts the attached Findings of Fact and Decision. All voted
in favor and the motion carried unanimously with a vote of 5 to 0.
PUBLIC HEARING:
DISCUSSION OF PROPOSED CODE AMENDMENT
Mr. Young-Walters stated this is an amendment for the variance timeline. Staff is proposing an
amendment to require a 500-foot mailed notification for appeals of administrative decisions and
to clarify the public hearing timeline for appeals and variances. City Code requires a mailed
notice to properties within 500 feet of a property requesting a variance but does not have a
similar requirement when a property appeals an administrative decision or code enforcement
action. The City Statute does not align with the State Statute in terms of review time for a zoning
request. Mr. Young-Walters clarified that this request would address both of those. Staff wants to
be sure individuals who may be impacted by these matters are notified and have a chance to
come to a public hearing and speak. There is a statutory 60-day review period and City Code has
a 45-day clause to set up a hearing with the Applicant; State law allows extension of up to 60
days and is not reflected in City Code. This would make it clear that the City has that authority
and increase transparency.
Chairman von Oven opened the public hearing.
Chairman von Oven closed the public hearing.
Commissioner Alto moved, Commissioner Johnson seconded that the Chanhassen
Planning Commission recommends that the City Council adopt the proposed ordinance
amending Chapter 20 concerning appeal notification and public hearing timeline
requirements. All voted in favor and the motion carried unanimously with a vote of 5 to 0.
APPROVAL OF MINUTES:
APPROVAL OF PLANNING COMMISSION MINUTES DATED JANUARY 4, 2022
Commissioner Noyes noted the summary minutes of the Planning Commission meeting
dated January 4, 2022 as presented.
ADMINISTRATIVE PRESENTATIONS:

year-in-review and a look forward to what is coming up in 2022 for the City. She shared that the
City had record building permit activity, lots of redevelopment and remodeling, and inspections.

numbers. Ms. Aanenson stated 2022 work projects anticipate 2% residential growth, some
