BACKGROUND The Saratoga 3rd Addition Planned Unit Development (PUD) ordinance was originally approved in 1998. This PUD incorporates a property with an existing 18-unit apartment building on it. The PUD ordinance allows for a total of 46 units across the site. Multiple concepts for this site have been brought to City Council work sessions for review, including a recently withdrawn application from the same applicant for a single, 59-unit apartment building. DISCUSSION RECOMMENDATION Staff recommends the approval of the requested site plan and planned unit development amendments. ATTACHMENTS Development Application Narrative Civil Plan Set Traffic Study Architectural Plan Set City Staff Report Redlined PUD Ordinance Findings of Fact Public Comment Santa Vera Affidavit of Mailing Affidavit of Publishing 4 5 6 Santa Vera Apartments Submittal Narrative Proposal Headwaters Development is proposing a redevelopment of the Santa Vera Apartments site (the “Site”) located at 621 Santa Vera Drive, located just north of downtown Chanhassen. The redevelopment will consist of the new construction of 28 townhome-style fiats, which will supplement the existing slab-on-grade 18-unit apartment building currently operating on-site. As part of the project, the existing building will also be renovated to include updated units, a new exterior, and improved landscaping and drainage. Once completed, the total project (the “Project”) will consist of 46 rental apartment homes. Site Location The Site is bordered by Laredo Drive to the east, Saratoga Drive to the north, and Santa Vera Drive to the northwest. Immediate adjacent uses are Chanhassen Elementary School immediately to the south, City Center Park to the west, and predominately single-family residential homes to the north and east. Santa Vera is located less than a ¼ mile from the City of Chanhassen’s Central Business District, and only steps away from employment centers, vital services, grocery stores, retail and entertainment, and a variety of dining options. Zoning and Land Use The Site is approximately 3.85 acres. The present zoning is PUD Residential, and the present land use designation has the property guided Residential High Density, which allows for 8-16 units per acre. The Residential High-Density guidance allows for up to 46 units by right. The Project is ideally located for these additional units given its proximity to employment and services, and the existing infrastructure currently in place is sufficient to handle the increased density. We are not requesting any waivers from the applicable zoning code. Site Design The design of the Site allows for separation from the existing neighborhood single-family homes. The proposed access to the Site would be from both Laredo & Santa Vera Drive. The Project will also adhere to all landscaping requirements, allowing it flt seamlessly into its surroundings and the existing neighborhood. New stormwater ponding will be constructed on the Southeast portion of the site – the natural low spot. This ponding will serve both the new townhome buildings, as well as treat the stormwater from the existing apartment building, which is currently released untreated into the municipal storm system. 7 2 Project Description Once completed the Project will contain forty-six (46) total units across three buildings. Twenty -Eight (28) units will be included in two newly constructed two-story buildings. Each new unit will have its own dedicated garage and direct access entry. The remaining eighteen (18) units currently exist within the two -story slab-on-grade building originally built in 1968. The Project will be constructed as one cohesive development through connectivity, architectural design, and shared amenities. The existing building contains a current unit mix of 8 one-bedroom units and 10 two- bedroom units. The newly constructed buildings, as currently contemplated, will contain a unit mix comprised of 10 one-bedroom units and 18 two-bedroom units. The following tables better illustrate the overall Project unit count and mix. Existing Building (built 1968) Units Avg. SF One Bedroom Units 8 785 Two Bedroom Units 10 890-990 Total Units 18 New Buildings Units Avg. SF One Bedroom Units 10 1,100 SF Two Bedroom Units 18 1,575 SF Total Units 28 Combined Units One Bedroom Units 18 Two Bedroom Units 28 Total Units 46 Parking and Amenities Interior flnishes will include hard surface countertops, hard-surface fiooring except for carpet in the bedrooms and quality lighting and plumbing flxtures. Most, if not all, units will have private balconies, in-unit washer/dryers, and all 2+ bedrooms in the new building will contain en-suite bathroom. Once complete each resident will have access to at least one enclosed garage stall. Overall, project will contain a total of 62 parking stalls, or 2.21 stalls per unit – a more than 2:1 parking ratio. Trash will be collected within the building footprint. It will be set out on the designated trash day and returned within the parking garage after collection. 8 3 The new building will include shared amenity spaces for all Project residents to enjoy, including a dog run, outdoor patio with grilling stations and a flre pit, and a trail connection to the existing city trail system. Architectural Design The project resides within the Saratoga 3rd Addition and will be required to comply with Chapter 20 of the Chanhassen City Code which provides guidance as to the expected architectural standards. Speciflcally exterior material be of high quality and durable, consisting of glass, wood or other quality materials as deemed acceptable by the city. The roof will be pitched with high quality shingles. Landscaping will meet or exceed the code, and signage will comply with the sign ordinance for residential districts. Sustainability The project will utilize many green building methods during construction and the Project itself will include low fiow plumbing flxtures, low VOC paints, LED lighting where appropriate. Currently the site does not treat any stormwater runoff. New stormwater ponding will be created with the Project utilizing the stormwater runoff from the site for irrigation of the proposed plantings. Financing and Affordability In addition to design, the Project also need to be flnancially viable. The project team is currently assessing how the tariff environment will affect construction pricing and what the current flnancing environment looks like for a smaller project such as Santa Vera. To upgrade the existing units, we expect a flnancing “gap” will exist that will need to be overcome in order to make the rehabilitation of the existing building viable. We will work with city staff to determine what city, county, and state funding tools are available for the creation and preservation of naturally occurring affordable housing (NOAH). We do not anticipate requesting TIF. Many of the existing units at Santa Vera already qualify as NOAH units. However, those units along with the existing exterior of the building are old and tired and in need of some updates. Any city, county, and/or state assistance will help aid in the renovations while also helping preserve the existing affordability. The overall Project aims to achieve slightly lower rents than the new luxury projects that recently opened and are currently under construction in Downtown Chanhassen. Given the allowed density and site constraints, Santa Vera will not be able to compete with the amenities provided at the Venue, Harlow, or Bennett. As such, it will not be able to command the top of the market rents. However, it 9 4 will serve a very important niche by providing housing to the missing middle – a very underserved segment of the current housing market. Given the investment and focus by the city’s leadership on creating a vibrant downtown, the preservation of existing NOAH units, along with the creation of new moderately priced rental homes near the city center is vital. Those that provide vital city services, as well as those that work at area restaurants, shops, and businesses should also be able to live near where they work. Santa Vera is uniquely located and positioned to expand the city’s housing options and help add to the vibrancy of the surrounding area. Phasing and Construction Schedule It is anticipated that the project will commence construction late fall of 2025. Initial activities will include site clearing, installation of utilities and infrastructure, rough grading and excavation, and then vertical construction. Simultaneously, renovations will occur in the existing 18-unit building. We will purposely keep at least one unit vacant in the existing building to serve as a “hotel” unit for residents to use while their unit is being updated. It is anticipated that the entire duration of construction will be approximately fourteen (14) months. Development Method Headwaters intends to develop and own the project for the foreseeable future. Headwaters is a Twin-Cities based company. The principals of Headwaters have a successful track record, and have been involved in the development, acquisition, and rehabilitation of over 5,000 units translating to over $2 billion worth of projects spanning the Midwest, Central Plains, and Mountain West regions of the Unit States. 10 DescriptionRev.DateSANTA VERA APARTMENTS CHANHASSEN, MINNESOTA07.11.2025CITY SUBMITTALSheet Title:Project #:Drawn By:Checked By:Issue Date:25-100PMJM04/04/2025G:\Shared Drives\Active Projects\Chanhassen\Headwaters Dev - Santa Vera Apartments\CAD\Sheets\COVER SHEET.dwgProject Title: HEADWATERS 6757 KARMEN AVENUE ALBERTVILLE, MN Client:Date: Lic.

The project is a 28-unit apartment / townhome development, which is immediately south of an existing 18-unit apartment complex. The main objectives of the study are to quantify existing traffic operations within the study area, evaluate potential impacts of the proposed development, and recommend improvements, if necessary, to ensure safe and efficient operations for all users. The following study assumptions, methodology, and findings are offered for consideration. Figure 1 Subject Site Subject Site Laredo Dr Kerber Blvd Del Rio Dr 78th St Powers Blvd (CR 17) 76th St Market Blvd 30 Santa Vera Residential Development Traffic Study July 18, 2025 Page 2 EXISTING CONDITIONS Existing conditions were reviewed within the study area to establish current traffic conditions to help determine impacts associated with the proposed development. The evaluation of existing conditions included collecting traffic volumes, observing transportation characteristics, reviewing crash history, and analyzing intersection capacity, which are described in the following sections. Traffic Volumes Vehicular intersection turning movement and pedestrian / bicyclist counts were collected on Wednesday March 26, 2025. The counts were generally collected from 7 to 9 a.m. and 4 to 6 p.m. with 13-hour counts (i.e., 6 a.m. to 7 p.m.) at the Kerber Boulevard / Santa Vera Drive and Laredo Drive / Saratoga Drive intersections. • Kerber Boulevard and Santa Vera Drive • Santa Vera Drive / Saratoga Circle and Saratoga Drive • Laredo Drive and Saratoga Drive • Laredo Drive and Del Rio Drive To illustrate how traffic volumes at study area intersections vary throughout the day, the traffic volume profiles by time-of-day are illustrated in Figure 2. Note that the adjacent Chanhassen Elementary School starts at 7:45 a.m. and ends at 2:15 p.m. Figure 2 Intersection Volume by Time of Day Transportation Characteristics Observations were conducted within the study area to identify various transportation characteristics such as roadway geometry, traffic controls, speed limits, and multimodal facilities. A general overview of key roadways within the study area is as follows: • Kerber Boulevard – a 2-lane undivided major collector roadway with multimodal facilities along both sides of the roadway. The speed limit is 40-mph with a 20-mph school zone speed limit near the elementary school. • Laredo Drive – a 2-lane undivided local roadway with a sidewalk along the west side of the roadway; the speed limit is 30-mph with a 15-mph school zone speed limit near the elementary school. All other study area roadways are 2-lane local roadways with limited multimodal facilities and a 30-mph speed limit. Each study intersection has side-street stop control. Existing geometrics, traffic controls, and volumes within the study area are shown in Figure 3. 0 50 100 150 Intersection VolumeKerber Blvd / Santa Vera Dr Laredo Dr / Saratoga Dr 31 550 550 700 650 1 5 0 300800303,7504, 0 0 0 1,300Figure 3Existing Conditions Santa Vera Residential Development Traffic Study Legend AM Peak Hour VolumePM Peak Hour VolumeEstimated ADT VolumeStop Sign XXX(XXX)X,XXX NKerber BlvdSanta V e r a D r Saratoga DrLaredo DrDel Rio Dr 0 (0)0 (0)0 (0) 0 (2)0 (0)16 (12)0 (0)20 (63)2 (9)0 (0)63 (42)1 (2)11 (16)149 (132)5 (3)9 (13)42 (200)4 (21)3 (3)9 (11)12 (13)8 (12)20 (5)12 (11)0 ( 0 ) 2 ( 1 ) 25 (28)1 (3) 24 (26)0 (0)0 ( 0 ) 8 ( 2 ) 4 ( 2 ) 0 ( 0 ) 3 ( 5 ) 17 ( 2 4 )1 (2)1 (1)23 (25)0 (0)3 (0)0 (1) 1 (10)30 (18)8 (19)11 (43) 12 (10)31 (24) 0 (0)3 (2)1 (3)19 (62) 0 (0)61 (42) 1,10032 Santa Vera Residential Development Traffic Study July 18, 2025 Page 4 Crash History Five (5) years of crash history were reviewed from 2020 through 2024 using MnDOT’s Crash Mapping Analysis Tool (MnCMAT), which identified two (2) intersection-related crashes within the study area. One (1) crash occurred at the Santa Vera Dr / Chippewa Trail intersection and one (1) at the Laredo Drive / 76th Street intersection. Neither crash resulted in a serious injury. Thus, there does not appear to be any existing safety issues in the study area from a crash frequency or severity perspective. Intersection Capacity Intersection capacity was evaluated using Synchro / SimTraffic Software (version 11), which uses methods outlined in the Highway Capacity Manual, 6th Edition. The software is used to develop calibrated models that simulate observed traffic operations, account for peaking characteristics, and identify key metrics such as intersection Level of Service (LOS) and queues. These models incorporate collected traffic, pedestrian, and bicyclist volumes, traffic controls, heavy commercial vehicle activity (i.e., buses and trucks), and driver behavior factors. Level of Service (LOS) quantifies how an intersection is operating. Intersections are graded from LOS A to LOS F, which corresponds to the average delay per vehicle values shown. An overall intersection LOS A though LOS D is generally considered acceptable in the study area. LOS A indicates the best traffic operation, while LOS F indicates an intersection where demand exceeds capacity. For side-street stop-controlled intersections, special emphasis is given to providing an estimate for the level of service of the side-street approach. Traffic operations at an unsignalized intersection with side- street stop control can be described in two ways. First, consideration is given to the overall intersection level of service, which accounts for the total number of vehicles entering the intersection and the capability of the intersection to support the volumes. Second, it is important to consider the delay on the minor approach. Since the mainline does not have to stop, most delay is attributed to the side-street approaches. It is typical of intersections with higher mainline traffic volumes to experience high-levels of delay (i.e., poor levels of service) on the side-street approaches, but an acceptable overall intersection level of service during peak hour conditions. Results of the existing intersection capacity analysis, shown in Table 1, indicate that all study intersections and approaches operate at an acceptable LOS B or better during the typical weekday a.m. and p.m. peak hours. In addition, peak queues at the study intersections range from about one (1) to two (2) vehicles. Note that there is increased activity for a short-duration (i.e., approximately 15 minutes) near the start / end times associated with the adjacent Chanhassen Elementary School. However, this increased activity does not significantly impact the study intersections or their operations. Thus, there are no significant existing operational issues from an intersection capacity perspective.

The proposed development is a 28-unit apartment / townhome development, which is immediately south of an existing 18-unit apartment complex. If approved, the site would have a total of 46 units (18-existing, 28-proposesd). For study purposes, the project was assumed to be open to residents in the year 2027. Access to the proposed development is planned via the existing driveways along Santa Vera Drive and Laredo Drive to the apartments, as well as one (1) new access to Laredo Drive across from Del Rio Drive. Six (6) of the new units would utilize the existing apartment driveways, while the other 22-units would utilize the new driveway across from Del Rio Drive. Sidewalk connections are planned to the existing City Center Park trail to the west, as well as the sidewalk along the west side of Laredo Drive. 34 Santa Vera Residential Development Traffic Study July 18, 2025 Page 6 TRAFFIC FORECASTS Traffic forecasts were developed for year 2028 build conditions, which represents one-year after opening. The traffic forecasts account for general background growth and trip generation from the proposed development. The following information summarizes the traffic forecast development process. Background Growth To account for general background growth in the study area, an annual growth rate of one (1) percent was applied to the existing traffic volumes to develop year 2028 background traffic forecasts. Note that historical ADT volumes within the study area have been steady or decreasing over the last 10+ years. Therefore, the assumed growth rate provides a relatively conservative estimate for analysis purposes. Development Trip Generation A trip generation estimate for the proposed development was created using the ITE Trip Generation Manual, 11th Edition, which includes trips for typical weekday a.m. and p.m. peak hours, as well as daily. The proposed development, shown in Table 2, is estimated to generate 32 a.m. peak hour (8 in / 24 out), 33 p.m. peak hour (21 in / 12 out), and 256 daily (128 in / 128 out) trips. No modal reductions were applied to provide a more conservative estimate. Note that the average trip rates for a low-rise multi-family residential unit represent 0.4 trips / unit during the a.m. peak hour, 0.51 trips / unit during the p.m. peak hour, and 6.74 trips / unit per day.

Site generated trips for the proposed development were distributed throughout the study area using the directional distribution shown in Figure 4, which is based on a combination of existing area travel patterns, the planned driveways, and engineering judgment. Figure 4 also shows the proposed development site trips at the study intersections. The resultant year 2028 build condition traffic forecasts are illustrated in Figure 5. YEAR 2028 BUILD CONDITIONS To understand impacts associated with the proposed development, a future intersection capacity analysis was completed for year 2028 build conditions. Results of the year 2028 build capacity analysis shown in Table 3 indicate that that all study intersections and approaches will continue to operate at an acceptable LOS B or better during the typical weekday a.m. and p.m. peak hours. Minimal change to intersection delays and queues are expected, which is a result of the relatively low trip generation of the proposed development and the reserve capacity within the adjacent roadway network. No operational issues are expected as a result of the proposed development from an intersection capacity perspective. 35 Figure 4Site Generated Trips Santa Vera Residential Development Traffic Study +15060% +105 +25+40+4 01 (3)0 (0)0 (0)1 (3)0 (0)0 (0)0 (0)1 (2)0 (0)3 (2)3 (1)3 (2)15% 10% 15% Legend AM Peak Hour Site TripsPM Peak Hour Site TripsADT Site TripsStop SignDirectional Distribution XXX(XXX)+XXX N 0 ( 0 ) 2 ( 2 ) 2 (6)1 (2) 7 (3)0 (0)0 ( 0 ) 0 ( 0 ) 0 ( 0 ) 0 ( 0 ) 0 ( 0 ) 7 ( 3 )0 (0)0 (0)2 (6)0 (0)0 (0)0 (0) 0 (0)2 (6)7 (3)0 (0) 0 (0)0 (0) 0 (0)3 (1)1 (3)7 (3) 0 (0)2 (9) 7 (3)0 (0)12 (6) 0 (0)0 (0)0 (0)4 (10)1 (3)0 (0)2 (6)3 (1)0 (0)36 670 650 825 695 1 5 5 310825303,9004, 1 5 0 1,500Figure 5Year 2028 Build Conditions Santa Vera Residential Development Traffic Study Legend AM Peak Hour VolumePM Peak Hour VolumeEstimated ADT VolumeStop Sign XXX(XXX)X,XXX NKerber BlvdSanta V e r a D r Saratoga DrLaredo DrDel Rio Dr12 (20)154 (136)5 (3)11 (16)43 (206)4 (22)3 (3)10 (13)12 (13)11 (14)24 (6)15 (14)0 ( 0 ) 4 ( 3 ) 28 (35)2 (5) 32 (30)0 (0)0 ( 0 ) 8 ( 2 ) 4 ( 2 ) 0 ( 0 ) 3 ( 5 ) 25 ( 2 8 )1 (2)1 (1)26 (32)0 (0)3 (0)0 (1) 1 (10)33 (25)16 (23)11 (44) 12 (10)32 (24) 0 (0)6 (3)2 (6)27 (67) 0 (0)65 (49) 1,2507 (3)0 (0)12 (6) 0 (2)0 (0)16 (12)4 (10)22 (68)2 (9)2 (6)68 (44)1 (2)37 Santa Vera Residential Development Traffic Study July 18, 2025 Page 9 Table 3 Existing Intersection Capacity Study Intersection Traffic Control Level of Service (Delay) AM Peak Hour PM Peak Hour Kerber Boulevard and Santa Vera Drive SSS A / B (11) A / B (12) Santa Vera Drive and West Site Access SSS A / B (10) A / A (9) Santa Vera Drive / Saratoga Circle and Saratoga Drive SSS A / B (10) A / B (10) Laredo Drive and Saratoga Drive SSS A / A (9) A / A (9) Laredo Drive and East Site Access (N) SSS A / A (9) A / A (9) Laredo Drive and Del Rio Drive / East Site Access (S) SSS A / B (11) A / B (10) SSS – Side-Street-Stop SITE PLAN CONSIDERATIONS A review of the proposed site plan does not indicate any major issues. However, the following items are offered for further consideration between the City and / or project team. • Locate signage and landscaping to avoid creating any sight distance issues. • Review truck maneuverability to limit potential internal circulation conflicts. • Install appropriate internal traffic controls (i.e., stop signs, etc.) per coordination with City staff. CONCLUSIONS Based on the findings of the study, the following conclusions are offered for consideration. 1) There are no existing intersection crash frequency or severity issues within the study area. 2) All study intersections and approaches operate at an acceptable LOS B or better during the typical weekday a.m. and p.m. peak hours. 3) The project is a 28-unit apartment / townhome residential development, which is immediately south of the existing 18-unit apartment complex. 4) Traffic forecasts were developed for year 2028 build conditions, which includes a one (1) percent annual background growth rate and trip generation from the proposed development; the proposed development is estimated to generate 32 a.m. peak hour (8 in / 24 out), 33 p.m. peak hour (21 in / 12 out), and 256 daily (128 in / 128 out) trips. 5) Results of the year 2028 build capacity analysis indicate that all study intersections and approaches are expected to continue to operate at an acceptable LOS B or better during the typical weekday a.m. and p.m. peak hours; no operational issues are expected because of the proposed development from an intersection capacity perspective. 6) No significant site plan related issues were identified, although the items noted above are offered for further consideration by the City and / or project team. 38 EM CS SARATOGA DRIVE LAREDO DRIVESANTA V E R A DRIVECHAIN LINK FENCE T T CABX CABX CABX HYDHYD N PROPOSED 12-UNIT BUILDING PROPOSED 16-UNIT BUILDING EXISTING BUILDING EXISTING GARAGES 3 2 '-8 " 60'-3" 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 22 3 4 4 S E TB A C K20'-0"SETBACK 20'-0" 1 BUILDING ENTRANCE 2 GARAGE ENTRANCE 3 DOG RUN 4 STORMWATER RETENTION SITE PLAN KEY kaas wilson architects Chanhassen Santa VeraSite Plan SD_100 07/10/2025 21036 1/64" = 1'-0"1 Site Plan 39 Level 1 100'-0" Level 2 110'-7 7/8" Truss Brg. 119'-9" 4.17.37.7 7.37.8 4.1 7.3 7.7 7.3 7.8 High Truss Brg. 130'-4 7/8" 7.67.3 7.7 7.37.7 Level 1 100'-0" Level 2 110'-7 7/8" Truss Brg. 119'-9" 7.6 26.1 7.3 7.7 6.17.6 7.3 7.76.1 7.6 High Truss Brg. 130'-4 7/8" 7.6 Level 1 100'-0" Level 2 110'-7 7/8" Truss Brg. 119'-9" 7.37.7 7.6 6.1 26.17.64.1 7.3 7.77.66.1 High Truss Brg. 130'-4 7/8" 7.3 7.6 7.3 Level 1 100'-0" Level 2 110'-7 7/8" Truss Brg. 119'-9" 7.6 4.1 7.3 7.7 7.3 7.37.7 7.3 7.87.8 4.1 High Truss Brg. 130'-4 7/8" 7.3 7.7 7.37.7 Level 1 to Mid-Point of Roof28'-9 1/2"EXTERIOR MATERIALS TAG KEY 5.1 ALUMINUM RAILINGS -

LOCATION: 621 Santa Vera Dr PID: 257620020 APPLICANT: Headwaters Development, LLC PROPERTY OWNER: Santa Vera Apartments, LLC PRESENT ZONING: PUDR – Saratoga 3rd Addition 2040 LAND USE PLAN: High Density Residential Public/Semi-Public SITE PLAN ACREAGE: 3.85 gross acres SITE PLAN DENSITY: 11.95 Units/Acre PROPOSED MOTION: “The Chanhassen Planning Commission recommends approval of the requested site plan and amendment to the Saratoga 3rd Addition Planned Unit Development Zoning Ordinance for the construction of two apartment buildings at 621 Santa Vera Drive, subject to the conditions of approval and adopts the attached Findings of Fact and Decision.” 46 Page 2 of 17 LEVEL OF CITY DISCRETION IN DECISION-MAKING: The city has a relatively high level of discretion in approving or denying PUD amendments because the city is acting in its legislative or policy-making capacity. A PUD amendment 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. COMMUNITY ENGAGEMENT Notice of the public hearing at the Planning Commission is required to be mailed to all property owners within 500 feet. The city sent notices to those properties, as well as additional adjacent properties, and in total, 376 notices were mailed notifying nearby property owners of this proposed development. The mailing list used for the public hearing notice was also used to notify nearby residents of the neighborhood open house held by the applicant and a subsequent letter update sent by the applicant. The Applicant and property owner met with the City Council on February 10, May 5, and June 9 to review sketch plans of the proposed development. The Applicant and property owner held a neighborhood open house at the Chanhassen Recreation Center on April 9, 2025, and sent a neighborhood flyer with a project update the week of July 28. The city sent an email update to the “Proposed Developments” email subscription group regarding the project on July 24. APPLICABLE REGULATIONS Chapter 20, Article II, Division 6, Site Plan Review Chapter 20, Article VIII, Planned Unit Development Standards Chapter 20, Article XV, Division 1 “R-12” District Chapter 20, Article 20-XXIII, Division 20-XXIII-9 Design Standards for Multifamily Developments Saratoga 3rd Addition PUD Standards PROPOSAL/SUMMARY The Applicant is proposing the construction of two apartment buildings containing a total of 28 units. The request consists of a site plan approval with a planned unit development amendment to facilitate the construction of these buildings and associated site improvements. 47 Page 3 of 17 The existing Planned Unit Development (PUD) Ordinance allows for multi-family residential which are defined as multi-storied apartments or condominium units. The PUD Ordinance prohibits Townhouses, Detached Townhouses, and Detached Single-Family Homes. City Code includes the following definitions: “Dwelling, Multifamily” as a detached building containing three or more dwelling units. Apartment buildings, condominiums, manor homes, quad duplexes, and cooperatively owned buildings containing three or more dwelling units are multifamily dwellings. “Dwelling, Townhouse” means a single-family attached dwelling in a row of at least three such units in which each unit has its own front and rear access to the outside, no unit is located over another unit and each unit is separated from the adjoining unit by one or more common fire- resistant walls having no openings and extending from the basement to the roof. Based on the city’s definition for “Dwelling, Multifamily”, the proposed 16-unit and 12-unit buildings are considered a multifamily dwelling which is allowed by the existing PUD ordinance. The site is located north of Chanhassen Elementary School and northwest of City Center Park. The property has vehicular access to both Santa Vera Drive and Laredo Drive. The site is zoned PUDR, with the underlying zoning of the R-12 District. The request is for site plan approval to construct two additional apartment buildings, one 12- unit building and one 16-unit building, on a site with one existing apartment building, which consists of 18 units. The total permitted site coverage is 65%. The proposed development has a total hard coverage area of 50.4%. The applicant is also requesting an amendment to the Saratoga 3rd Addition Planned Unit Development Zoning Ordinance. The applicant has requested modifications to the exterior building material requirements and parking space setbacks. STAFF RECOMMENDATION Based upon the foregoing, staff is recommending approval of the requested site plan and PUD amendment with conditions as outlined in this staff report. SITE PLAN REVIEW This building must comply with the Design Standards in the Saratoga 3rd Addition PUD. The PUD requires that the development demonstrates a higher quality of architectural standards and site design, and use durable materials. Site coverage may not exceed 65%. The total hard surface coverage proposed on the site is 50.4%. The design of the building is attractive and is proposed to be constructed of high-quality materials. They include a mix of lap siding and board and batten siding for the main body of the building and cultured stone and cedar timber as 48 Page 4 of 17 accent materials. All elevations have received equal attention, and the building has a pitched roof. The added landscaping will buffer the proposed multi-family buildings from the surrounding elementary school and single-family neighborhoods. The applicant is requesting an amendment to the planned unit development pertaining to building materials. The existing PUD requires that the majority of all exterior surfaces shall be face brick, stucco with metal, wood, rock face block and stone accents. To maintain the intention of the PUD but to allow for more flexibility and timelessness to the required materials, staff recommends the following updated language within the PUD Ordinance: “Acceptable exterior materials shall be limited to vinyl lap siding, face brick, stucco, wood, rock face block, or stone. Buildings may have metal accents, but the metal accents may not exceed 15% of the building elevations.” The applicant is requesting an additional amendment to the planned unit development pertaining to parking setbacks. The PUD requires a 50-foot parking setback from lot lines with road frontage and all interior lot lines. The applicant requests to reduce the setback to 30 feet for lot lines with frontage and 20 feet for interior lot lines. The requested parking setback brings the existing surface parking lot into compliance and the site plan improvements will ensure that new parking is adequately screened from adjacent properties.

For two-bedroom and larger units: two stalls shall be provided per unit, and one must be completely enclosed in a garage. Additionally, one visitor parking stall shall be provided for every four dwellings. # of Units # of spaces per unit # of Parking Stalls Required 16-Unit Apartment 1 Bedroom Units 10 1.25 (1 enclosed) 13 (10 of which enclosed) 2+ Bedroom Units 6 2 (1 enclosed) 12 (6 of which enclosed) 12-Unit Apartment 1 Bedroom Units 4 1.25 (1 enclosed) 5 (4 of which enclosed) 2+ Bedroom Units 8 2 (1 enclosed) 16 (8 of which enclosed) Total # of Units Guest Parking Requirement # of Guest Parking Required 28 1 space per 4 units 7 Based on the project as proposed, a minimum of 46 resident parking spaces are required, with at least 28 of the spaces being enclosed. The project as proposed provides for 28 enclosed parking spaces and an additional 28 surface parking spaces to meet the required 46 resident parking spaces. The project is also required to have at least 7 guest parking spaces. The project as proposed provides for 6 guest parking spaces. One additional guest parking space is required to be added to the site plan. Staff have identified space for an additional guest parking stall on the eastern edge of the currently shown 6 guest parking spaces. Site furnishing The property is proposed to contain communal resident amenities such as patio, a grill station, and a dog run. The project as proposed maintains the existing sidewalk connection along the length of Laredo Drive connecting to the trail on the north side of the Chanhassen Elementary property. A 36” chain link fence is proposed to run parallel to this sidewalk to deter access to the southern storm water pond. Neighborhood feedback during the open house included the desire to see a sidewalk added along the south sides of Santa Vera Drive and Saratoga Drive for the benefit of future residents as well as those who park along those roads in the summer and walk to the adjacent baseball 50 Page 6 of 17 fields. The addition of these sections of sidewalk would be at the expense of additional tree removal, some of which are ash trees, while others are identified as silver maples. Loading, mechanical, and refuse areas The PUD requires that all mechanical equipment shall be screened with material compatible to the building. Individual units are shown to have residential size air conditioning units. Condensing units are planned to be located on-grade, on the east and west sides of the 16-unit building and on the north and south sides of the 12-unit building. The landscaping plan shows a mixture of hydrangea, honeysuckle, hosta, and sedum plantings as screening for the proposed air conditioning units. The proposed sceening appears reasonable; however, does require an amendment to the existing PUD Ordinance as the ordinance indicates building materials to be used as screening rather than landscaping. No central garbage and recycling services are proposed. Instead, each tenant will keep their own garbage and recycling bins internal to their units and will, therefore, not require any additional screening. The existing Santa Vera apartments have a garbage shed that has two dumpsters: one each for recycling and garbage, with garbage pickup occurring twice a week and recycling pickup once a week. Lighting The Saratoga 3rd Addition PUD requires that all light fixtures shall be shielded, light fixtures shall not exceed 20 feet in height, and light levels shall be no more than ½ candle at the property line. City Code requires that lighting on the building faces shall also be restricted to having a total cutoff angle equal to or less than 90 degrees. The architectural building elevations show ornamental lighting over all apartment entrances as well as some garage entrances and windows. Each of the fixtures is below 20 feet and has a cutoff angle equal to or less than 90 degrees. The site plan proposes five drive aisle street light poles with foundations. Heights must be provided for these lights and must adhere to the 20- foot maximum height requirement per the existing PUD ordinance. Signage Plans provided do not depict a final signage plan for the site. Signage for the property shall comply with City Code Section 20-1301 and all other applicable regulations to the site. Sign permits will be required to be applied for and reviewed at the time of building permit. LANDSCAPING AND TREE PRESERVATION The applicant for the Santa Vera Apartments submitted tree canopy coverage and preservation calculations. The submitted plans show that tree canopy to remain will not meet canopy coverage requirements. As a result, plans must include a reforestation plan to bring the total canopy coverage back to the minimum requirement. 51 Page 7 of 17 Total upland area (excl wetlands, bluff) 3.85 acres Baseline canopy coverage 1.22 acres Minimum canopy coverage required 0.77 acres or 20% Proposed tree preservation 0.44 acres or 11% The applicant must bring the canopy coverage on site up to the 0.77 acres which equates to the 20% minimum. The difference between the required coverage and the remaining coverage is multiplied by 1.2 for total area to be replaced. One tree is valued at 1,089 SF. Minimum required 0.77 Less canopy preserved 0.44 Minimum canopy coverage to be replaced- 0.33 Multiplied by 1.2 0.39 acres or 17,249.8 sf Divided by 1089 sf = Total number of trees to be planted: 16 The applicant has submitted a landscape plan showing a total of 47 trees to be planted in the site plan which exceeds canopy coverage requirements. The applicant shall adjust quantities to meet diversity requirements. No more than 30% of the trees can be from one family, no more than 20% from the same genus and no more than 10% of the same species. Vehicular Use Area Requirements Staff have analyzed the site plan and found that additional screening on the site has satisfied the requirements in Sec 20-1181. In addition, the applicant is providing the required landscaping within the vehicular use areas. Buffer yard requirements The PUD Ordinance establishes that landscaping along streets shall comply with buffer yard standard B and interior lot lines shall comply with buffer yard A. Buffer yard A shall be 10 feet in width. A landscape plan must be approved as part of the site plan review process. Required plantings/landscape area Buffer yard B – East Prop.

The landscaping plan includes 47 trees, 179 shrubs, and 227 perennials. This is in addition to the 35 trees identified to be saved on site, bringing the total number of trees proposed to 82. Based on the trees to be preserved and the new plantings, the buffer yard requirements appear to be met. The Applicant shall provide a breakdown of how existing and proposed plantings satisfy the buffer yard requirements. BUILDING ARCHITECTURAL REVIEW Required architectural standards Based on the proposed development site being zoned as a residential planned unit development, the building must meet the design standards established by the Saratoga 3rd Addition PUD. Massing and Placement The architectural style is known as a “flat” because each unit has a private entrance and no shared interior space. The building rhythm provides proper visual articulation and harmony with the surrounding area. The buildings have pitched roofs, as required by the PUD. The buildings are located on the property's south and west sides, offsetting them from adjacent roadways and provides a buffer from the surrounding single-family development. Building Height The architectural elevations, as provided, propose a building height of 30.4 feet for the 12-unit building and 26.05 feet for the 16-unit building. City Code establishes that building height shall be measured the vertical distance between the highest adjoining ground level at the building and the average height of the highest gable of a pitched roof. The proposed buildings adhere to the PUD ordinance restriction of 35 feet. 53 Page 9 of 17 Elevations 54 Page 10 of 17 Renderings 55 Page 11 of 17 Materials and Color The proposed building contains four main materials: board & batten, lap siding, cultured stone, and cedar timber. The design pulls from the architecture of the existing building on the site, while providing a more modern feel and style. While these materials do not comply with those listed in the existing PUD, staff recommend the approval of the revised PUD language, which provides increased flexibility in materials. The applicant is providing a variety of both high-quality and durable materials. PROJECT OVERVIEW – ENGINEERING AND WATER RESOURCES The Applicant is requesting a site plan review of a 28-unit multi-family apartment project located just north of downtown Chanhassen. Construction plans and Stormwater Reports developed by Measure Group dated July 21, 2025, were reviewed by staff. The proposed design would create 1.11 acres of new impervious area in the form of an apartment building, parking lots, sidewalks, and streets. Stormwater is proposed to be managed by two storm water ponds along Laredo Dr. TRAFFIC A traffic study for the proposed Santa Vera Apartments was completed by TC2 on July 18, 2025, by Matt Pacyna. The project proposes to continue using the three existing access points: two on Laredo Drive and one on Santa Vera Drive. The adjacent street network—Laredo Drive (1,300 ADT), Santa Vera Drive (700 ADT), and Kerber Boulevard (4,000 ADT)—remains within the capacity thresholds for their respective classifications. City staff has reviewed the study and found the estimated trip generation to be relatively low. During peak hours, 24 vehicles are expected to exit and 21 to enter the site. The development is projected to add approximately 256 daily trips, with most of the additional traffic distributed 75/25 between Laredo Drive and Santa Vera Drive. Even with this increase, the affected streets are projected to remain within their functional classification capacities. An addition to the traffic study shall be made to incorporate a traffic sight line review at the access to Santa Vera Dr. and both access points on Laredo Dr. The applicant shall update the construction plans with any additional information following this addition. SANITARY SEWER & WATER MAIN The applicant is proposing construction of 4” PVC for the sanitary sewer and 6” for the watermain. Service connections are proposed to be separate 4” fire & 2” domestic for water and 4” for sanitary sewer. Plans that illustrate the profile of the utilities along with their size and material are required for review and approval prior to final plan approval. The proposed sanitary sewer and watermain are undersized for the city to own and maintain them. The 56 Page 12 of 17 applicant is expected to complete the revisions and coordinate additional reviews to identify if any of the proposed utilities are private or publicly owned. GRADING & DRAINAGE In the existing condition stormwater on the site generally flows from west to east. City Center Park, which borders the property to the west, is located at a high point, with runoff leaving the park in all directions, including runoff that flows through the Santa Vera site. On the project site, stormwater primarily flows overland through a conveyance depression that directs most of the site’s runoff to three catch basins located at a low point along Laredo Drive. Currently, stormwater from the site is collected and conveyed by public infrastructure, including storm sewers and wet ponds, before ultimately discharging into Lotus Lake. There are no public or private stormwater Best Management Practices (BMPs) located on the property. As a result, pollutants generated on-site are carried downstream and treated solely by the city’s infrastructure. The project site lies in an older area of Chanhassen that was developed in the 1960s and 1970s, before current stormwater management standards were adopted. As a result, the area lacks sufficient BMPs, contributing to higher pollutant loads reaching Lotus Lake. The redevelopment of the Santa Vera property presents an opportunity to address these deficiencies by incorporating stormwater treatment measures that go beyond current regulatory requirements. PROPOSED CONDITIONS Under the proposed development plan, the site will be mass graded to accommodate new apartment buildings, a parking lot, driveways, and stormwater reuse basins. Drainage patterns will remain generally consistent with existing conditions. The northern portion of the site will remain unchanged and continue draining toward the storm sewer on Saratoga Drive. Runoff from the proposed buildings, parking lot, driveway, and part of the existing apartment building will be collected via storm sewer and directed to the stormwater reuse basins located on the east portion of the site adjacent to Laredo Drive. These reuse basins will be connected by storm sewer and discharge to the existing storm sewer system on Laredo Drive through a single outlet. Stormwater treatment for the proposed impervious surfaces will be provided through a combination of stormwater basins and a reuse system designed for irrigation. The site is currently zoned as Planned Unit Development (PUD). However, preliminary development plans propose changes in the previously approved PUD and relief from sections of City Code to facilitate the proposed plan. In return, it is recommended that the applicant provide enhanced water quality treatment to reduce the burden on downstream stormwater infrastructure. The stormwater basins along Laredo Drive appear to be too high in elevation to direct and treat stormwater from the adjacent area, however, there appears to be an opportunity to route stormwater from Saratoga Drive into the proposed stormwater basins. 57 Page 13 of 17 Additional engineering calculations are needed to understand if this is a viable option. As such it is recommended that the applicant work with staff to optimize the stormwater design and assess opportunities to provide stormwater treatment in excess to the requirements. If the design was reconfigured to treat stormwater by the public ROW, the city may provide relief to the project by reducing stormwater development fees and/or taking on the ownership and maintenance of the stormwater treatment system depending on the amount of excess stormwater treatment provided. EROSION CONTROL The proposed development will create greater than one (1) acre of land disturbance and therefore will 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). A Surface Water Pollution Prevention Plan (SWPPP) was included in the preliminary site plan submittal. The SWPPP is a required submittal element for final site plan review along with the Erosion and Sediment Control Plan (ESCP) in accordance with Section 19-145 of City Code. No earth disturbing activities may occur until the SWPPP is formally approved. This SWPPP shall be a standalone document consistent with the NPDES Construction Permit and shall contain all required elements 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. An updated SWPPP shall be submitted and approved prior to recording the final site plan agreement. All erosion and sediment control BMPs shall be installed and inspected prior to initiation of site grading activities. STORM WATER MANAGEMENT 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.” These standards include abstraction of runoff and water quality treatment resulting in the removal of 90% total suspended solids (TSS) and 60% total phosphorous (TP). The proposed project is located within the Riley Purgatory Bluff Creek Watershed District (RPBCWD) and is therefore subject to the watershed’s rules and regulations. A RPBCWD permit will be required for final site plan approval. A Stormwater Management Report is required to be submitted for review to confirm all applicable stormwater management requirements are being met. This includes rate control, volume abstraction and water quality requirements among others. The site proposes to meet stormwater management requirements through the use of stormwater basins and reuse system. The applicant shall confirm that the reuse system will provide enough water for the proposed irrigation system based on the drainage area and the storage in the tank. A backup potable connection may be needed. Currently the TSS removal requirements and TP removal requirements are being met on site. The applicant shall provide final versions of all 58 Page 14 of 17 modeling (Hydro CAD and MIDS) and Stormwater Management Report to address remaining comments and confirm rate, volume and water quality requirements are met as part of the final site plan approval. The stormwater basins do not appear to meet the 3-foot freeboard requirements to the existing and proposed buildings onsite. As such the applicant shall revise the design to meet the stormwater design requirements outlined in City Code. The proposed stormwater management systems shown in the preliminary site plan are to be privately owned and maintained. An operations and maintenance plan is required to ensure that the private stormwater infrastructure is maintained in good working order. The maintenance plan includes descriptions of maintaining the BMPs, maintenance schedule, responsible party, and information on how the system will be cleaned out.

Avienda Apartments Preliminary Plat and Site Plan Review (Planning Case 25-08) Rachel Arsenault, Associate Planner, introduced Planning Case #25-08 for the Avienda Apartments Preliminary Plat and Site Plan Review. The case is scheduled for the City Council on June 23. The proposed location is near Lyman and Powers. The land is zoned planned unit development, and the land designation is office and commercial. Mrs. Arsenault reviewed the communication up to this point, including a City Council Work Session on March 24, 2025, a neighborhood meeting on March 25, 2025, and a notice of the public hearing mailed to all property owners within 500 feet. She reviewed the greater Avienda PUD, which included 768 approved united, 39 detached townhomes, 52 rowhomes, 412 apartments, and 264 additional units that could be built. She said that the senior housing development is no longer planned. She reviewed the level of city discretion in decision-making. She stated that the staff reviewed seven considerations for subdivision approval and found that all were met. She reviewed the preliminary plat and noted that they were platting one lot, with the remainder of the 37 acres designated as an outlot. She said anything that comes forward from the outlot would need to be replatted and presented to the Planning Commission. She provided context for the site plan review and noted that it was updated yesterday, so the staff had not fully reviewed it to make sure it met all the conditions. She said that the site plan in the agenda packet was the original version in which the staff conditions were created. She 93 Planning Commission Minutes – June 3, 2025 2 commented that the pedestrian connectivity was highlighted in the site plan review because that is a large part of the Avienda Development. She said that the development team had already worked toward some of the conditions to allow public access easements to provide public benefit for anyone living in the Avienda Development. The site plan shows a pet park and connecting trails on the north end of the site, along with public parking and an entrance to the garage. She reviewed the middle of the site plan, which provided parking and pedestrian access around the building. She reviewed the south end, which provides another pet park and trails to walk around. She summarized the landscape plan and said that there is berming on the north side, which would create a visual interest. She stated that the courtyard was a large part of the landscaping for the development. She commented that the south end of the development mirrored the north side with trees and berming. Mrs. Arsenault summarized the parking requirements for different unit types and commented that the city is requiring 726 parking spaces, 412 of which are to be covered underground spaces. She stated that the developer was providing 736 parking spaces, but 101 of those spaces would be considered proof of parking. She explained the layout of the floor plan and the underground parking garage. She commented that the underground parking garage would contain the trash rooms and the utility areas. She reviewed the architecture for the outside of the building and the rendering photos. She said that the Avienda Design Guidelines are recommendations, not requirements, but that the design drivers are timeless architecture, earth-tone color palates, inclusive opportunities to relax and gather, and pedestrian accessibility. She explained that certain concept materials were used most often in the project, and she provided material samples at the podium. She stated that the Avienda Design Guidelines referenced material classification, which includes natural stone, architecturally pre-cast panels, and wood. Joe Seidl, Water Resources Specialist, discussed the grading and drainage. He said that the area was previously graded with the larger Avienda build-out. He stated that there was a high point in the center of the site, which directed stormwater to the north to be picked up in a temporary basin and conveyed to the northwest via storm sewer or to the south through drainage swales to a temporary basin, which drains to Lake Susan. He noted that there is the planned Avienda row homes development, which has the best management practice highlighted in pink and was stabilized with vegetation. He said that the project was required to meet city and Riley Purgatory Bluff Creek Watershed District Requirements for water quality, rate control, and water volume. He said that the proposed design includes stormwater ponds and best management practices to promote infiltration, filtration, and stormwater storage. He said that the stormwater site was outlined in the Apartment’s stormwater management report and a master report. He reviewed the stormwater master plan, which was a road map to guide how the stormwater would be managed for the entire site to allow for fewer and larger best management practices. He said that there would be more assets if there were smaller, but best management practices, so the regional plan would think on a large scale of how the stormwater would naturally run along the site. He stated that there would be extra complexity with the Avienda Apartment buildout, because the stormwater for their site needs to meet standards and they are using portions of the master stormwater plan, so the plans have to talk with one another and consider the maintenance for the best management practices and both plans would have to go through permitting at the same time. 94 Planning Commission Minutes – June 3, 2025 3 Mr. Seidl summarized the proposed conditions for the grading and drainage and said that the storm sewer would be built and convey water to a pickup point to be captured and conveyed by the master stormwater drainage to a best management practice on the north side of the buildout. He said a temporary basin would be reconfigured into an underground system. He said that the underground system would primarily treat the stormwater from the public roadway and would be conveyed to the northwest. He noted that this would be a better picture of the Avienda Rowhomes buildout, and the stormwater would have to work with this design. He stated that there was an emergency overflow route planned through the southern portion of the site. He said that the center courtyard acts like a bowl and would inhibit an overflow path, so they would need to find a solution, such as a redundant pipe that was sized correctly, if the primary pipe was not functional. He discussed the stormwater challenges, including navigating the master plan and making sure that there was an accounting exercise completed based on the impervious area created, the amount of treatment in the best management practice remaining, and how to route them. He discussed the challenge with the relocation of the best management practice and undergrounding it. He said that the best management practice was alleviating stress downstream to temporarily store stormwater. He asked if a temporary reroute was necessary, and they would need to study the potential impacts with the city. He discussed the design of the overflow system and the maintenance of the best management practices. He said that there are engineering solutions that need to be implemented. Commissioner Rosengren asked about the proof of parking spaces. He said that the plan looked like the areas were spread around the outside edges of where the parking lots would go. He asked if these areas would be paved but not have parking lines until they are needed. Mrs. Arsenault answered that the parking spots would be planned, but they would not be pre-paved. She said that they would be graded properly so they could change it into parking, but there would be landscaping in the interim to be used for the site currently. Commissioner Rosengren asked if there would be an impact on the water plan if they paved additional areas for parking. Mr. Seidl answered that the city would have to review whether the parking was reconfigured. He said it was not uncommon for either an emergency overflow route to go over a parking lot, or for there to be an underground pipe solution. Commissioner Rosengren clarified that nothing major would impact the plan. Commissioner Jobe asked what the trigger would be for when parking would be added. Mrs. Arsenault answered that parking was only required to be constructed if and when they find a need for the spaces. She said if the city receives repeated, reported issues, they will work with the developer to construct the parking. Commissioner Jobe asked about the water flow, since this was a design-as-you-go. He asked how much flexibility that allowed to change things for the next addition. Mr. Seidl answered that the fundamentals of the plan would not change much. He said that when he looked at a master plan, there would be a large, best management practice in a general area to capture and convey water from the developments. The main goal of the individual development was to figure out how to route the stormwater to the best management practice and to make sure they were still 95 Planning Commission Minutes – June 3, 2025 4 sized correctly. He said if there was a change, the master stormwater plan would have to re- permit itself. Chairman Noyes asked if the last part to be developed might be stuck with a situation they could not deal with based on minor tweaks. Mr. Seidl answered that the city needs to regulate each project. The nice thing is that the area is fairly built out, so there is not a lot of the impervious area to go higher than what was planned for. He said that the biggest risk was if there were no credits left, but the risk was low if it was managed correctly. He stated that there were two sets of regulatory eyes looking at the project. Chairman Noyes asked if the undeveloped parking was considered impervious or pervious in the calculation. Mrs. Arsenault answered that it was considered impervious. Commissioner Jobe asked if the sod would be required to prevent nitrates from going into stormwater areas. Mrs. Arsenault answered that there was not a requirement for specific sod planting, but there were landscaping requirements reviewed by the Natural Resource Specialist. These items would include ensuring enough tree plantings and species diversity. Commissioner Olmstead said that there was a slide in the site plan that calculated for hammerheads on the northwest and southwest corners for ambulance turnaround, but there was not good coverage on the west side of the building, which would have the best management practice for the rowhomes and a small, private lane. He asked if fire was acceptable to that. Mrs. Arsenault answered that the fire had reviewed the plans and had no conditions. Commissioner Trevena requested to review the east-west paths for future retail. She said it was just on this parcel, and the retail developer would have additional responsibility. Mrs. Arsenault confirmed and answered that this development provided multiple connections to the commercial area. Commissioner Olmstead asked if traffic control would be a part of the final review. He asked about the four-way stop and if it would be required. Mrs. Arsenault answered that it would be a part of the traffic study that the development team would have to complete and update. Mr. Seidl clarified that this would be like the stormwater plan, and there were outlined uses, but as the individual uses of parcels were known, they could update the traffic study. They could condition an upgrade if it was necessary for whatever development triggered the upgrade. Commissioner Olmstead said it worried him when plans were piecemealed. He said the regulators would have to look into the future to help the next person. Commissioner Soller asked about the marked yellow trails on the plan and interconnectedness. He asked if they are to be privately maintained areas or if they were public sidewalks. Mrs. Arsenault answered that the outermost ring was designed to ADA standards and city standards, so the public could use it. She would have to double-check with the engineering department about who oversaw the maintenance. 96 Planning Commission Minutes – June 3, 2025 5 Commissioner Soller said that it was designed with the intent to allow for public foot traffic, not just a benefit for the residents of the building. Mrs. Arsenault confirmed that this was the intent, and this was a large part of the Avienda review and design guidelines. Chairman Noyes asked if the pedestrian areas left the development and how they would meet up with the next development in appropriate places. Mrs. Arsenault answered that it was a best- guess assumption, but they can make a good guess based on the traffic. She said that the developer only had to construct one path on the east side because there was no reason to go east a couple of feet to their property line if they did not know where it would connect with commercial developments in the future. Commissioner Grover asked if some of the paths went through the proof of parking areas. Mrs. Arsenault answered that the developer would have to reconstruct the sidewalks in front of where the proof of parking space would go and there is sufficient space to do so. Commissioner Rosengren clarified that the proof of parking was all or nothing. Mrs. Arsenault answered that the proof of the parking agreement wording could be further worked through in the development contract. She said that the 101 parking spots would meet the minimum requirements for the City Code. Commissioner Jobe asked if the proof of parking was like an escrow account and how soon they would know if they needed the proof of parking. Jacquel Hajder of Inland Development Partners, LLC team said that the proof of parking came from a portfolio of projects they already had that were from similar markets and had 95 to 98 percent occupancy. She said that they did not want to overbuild, but they did not want to have an excess of hard surfaces, which are not as good for the environment. She said they typically see a need for 1.5 parking spots per unit. She stated that they look at how many stalls they have per bedroom. They have 1.1 parking stalls per bedroom. She said it took about 18 to 24 months to see the building occupied and to understand the parking needs. She said they have a management company that oversees the parking to make sure one resident is not storing many cars. Commissioner Trevena asked about the EV readiness was limited to 20 percent of the interior stalls. She asked if there was a timeline or threshold to increase the amount. Jacquel Hajder that EV-ready meant providing conduits and transformers to allow for twenty percent of the parking to be electric vehicle charging. Ten percent of the stalls would already be completed. She said many buildings are not yet meeting the demand for electric vehicle charging. Chairman Noyes opened the public hearing. John Gilbert, 1641 Jeurissen Lane, said he appreciated the complexity of the water movement. He thought the incremental changes still worried him and that someone would be left holding the bag. He looked back at the previous approval of row homes and the 500-foot pond. He asked if anyone considered moving the water from the courtyard. He said he endorsed approving the project with conditions. He said that the water was driven to a location that was not being voted on tonight. He stated that there were several renditions of what the developer wanted to see for Avienda. He commented that there was a community center in earlier plans seen in the watershed 97 Planning Commission Minutes – June 3, 2025 6 documents. He asked if there were any other options to move water to the 500-foot pond. He said he would love to see the courtyard mirrored on the east side of the property, since that was originally presented to the community. He read some references and asked if the developer was trying to get the city to commit to the pond because they need the water moved there. He asked if there were any other options available. He said that the grading plan showed a courtyard to the basins. He stated that the Avienda Quad was cited in the landscaping plan. He thought there would be very little water flow going through the area right now, and if there were any other solutions. He asked if the city could come up with a longer-term plan, and that they were being shortsighted. Chairman Noyes closed the public hearing. Chairman Noyes recognized that it was a fluid project, and the Planning Commission built safeguards in for further reviewing and further opportunities for public discussion for future projects. He said that the discussion would continue as other parts of Avienda were developed, whether it was as simple as walking paths or as complicated as water movement. Commissioner Olmstead asked if the 46 comments were the conditions of approval. Mrs. Arsenault confirmed that the 46 comments were the conditions of approval that would need to be addressed before coming forward for the final plat. Even when it comes to the final plat, they do another plan review, which could include additional conditions. Commissioner Olmstead clarified that the developer had sent in updates that addressed some of the conditions. Mrs. Arsenault confirmed this information. Commissioner Olmstead moved, Commissioner Jobe seconded that the Chanhassen Board of Appeals and Adjustments approves the requested preliminary plat and site plan review subject to the conditions of approval and adopt the attached Findings of Fact and Recommendation. All voted in favor and the motion carried with a vote of 7-0. GENERAL BUSINESS: None. APPROVAL OF MINUTES: 1.
