FISHER JOSEPH GITIS THOMAS P."TI M" STOLTMAN LINN J. FIRESTONE ..PRESENTLY ADMITTED ONLY IN PENNSYLVANIA CITY OF CHANHASSEN RECEIVED it]N 11981 COMMUNITY DEVELOPMENT DEPT. At your request, I have reviewed the various comments received to the Lake Ann EAW. The only one that deserves any discussion, as you indicated, is the request by the Minnesota Historical Society for an archaeological survey. The Historical Society did not request an Environmental Impact Statement. Nevertheless, you have indicated some concern about the property response to the request for the archae- ological survey. I believe the appropriate response is silence. If, however, you wish to respond, I believe there are a number of reasons why an archaeological survey ought not be undertaken: 1. A substantial portion of the Lake Ann PRD will remain in public ownership Eighty feet landward from the ordinary high-water mark along the lakeshore is being dedicated to the City. In addition, 34.4 acres of the site is being transferred to public ownership as an addition to the Lake Ann Park: 22.8 acres is dedicated; 11.6 acres will be purchased by the City. 2. The undedicated portion of the site proximate to the Lake Ann shoreline has been under cultivation for years. As a consequence, the site with which the Historical Society has expressed concern, has undergone "exten- sive alterations." Note that the last paragraph of the Historical Society's letter specifically indicates that extensive alteration is a premise for a re-evaluation of a need for a survey. This was pointed out in the EAW, but apparently missed by the Historical Society. 3. The Historical Society has no legal authority to require a survey. In light of the substantial dedication involved in this development, even if archaeological sites were to be discovered, governmental agencies would have to compensate the land owner for any additional lands required to be LARKIN, HOFFMAN, DALY & LINDGREN, LTD Mr. Robert Waibel May 29, 1981 Page 2 undisturbed due to archaeological findings. I doubt that the City wishes to incur that expense. The Historical Society has no funds for such an expense. Please contact me if you intend to prepare a written response to the Historical Society's comments. If you have any questions or comments, please give me a call. Sincerely yours, David C. Sellergren, for LARKIN, HOFFMAN, DALY & LINDGREN, Ltd. Sig cc: Ed Dunn, Dunn & Company We, the undersigned, request that the Chanhassen Planning Commission & Chanhassen City Council reject the development of Lake Susan and Lake Ann as presented by Dunn. and Curry. We.propose that the development submitted by Dunn and Curry be limited to single family homes with a maximum of 2 units per acre. We also request that the green areas be expanded to include existing wooded areas as shown on the attached illustration; or that the illustrated wooded areas be substituted for a portion or all of the proposed planned unit development open space in order to preserve the unique topography of the land, continue to provide a habitat for the natural wildlife and preserve the few remain- ing wooded areas within this part of the City. We also ask that the commercial areas be zoned single family residences. We feel that the proposed development -by Dunn and Curry will have the following adverse impacts on the community. I. The current proposal will add 3669 people on approximately 500 acres in the Lake Susan Development and 1823 people on 220 acres in Lake Ann within 5 years. A. Dunn and Curry's density estimate contains discrepancies. They claim -that the density of the Lake Susan,.South development is 2.4 units/acres. In reality, the unit per acre is 2.8, 447 units built on 158.5-acres. In the Lake Susan West development, Dunn and Curry claim a development of 3.0 units per acre. In reality, it is 3.8.units per acre, 1023 units on 272 acres. In the Lake Ann development, Dunn & Curry claim 3.66 units per acre. In reality, it is 4.5 units per acre.. The reason for the'apparent discrepancies is that Dunn and Curry included commerical areas, road right-of-ways and outlots which do not accurately represent the true land use. B. Out of approximately 1500 housing units planned for the Lake Susan development, 2/3 are multiple dwellings, consisting of duplexes, quads, 8 plexes, townhomes and apartments. Out of -1- �. approximately 790 units planned for Lake Ann, 620 will be multiple dwellings. We find the number of multiple units to be destructive to the community spirit.- Renters, as evidenced by other communities, traditionally -have not -been active participants in the community as they do not,have a vested interest in -the upkeep of the property. C. Typically planners attempt to locate high density multiple dwelling units -adjacent to the -Central Business District, a practice not being .followed under the present proposal. Here multiple units are being proposed adjacent to.exi sting single family dwellings. The adverse property value impact on existing single family dwellings will be.substantial, due to adjacent high density development. D. Dunn and Curry's plans for the two lakes are also inconsistent. The property adjacent to Lake Ann is planned for single family development; however, the property adjacent to Lake Susan is proposed!to.be`multiple_dwel,lings. Areas adjacent to both lakes should .be designated for 'si ngl e ' fami ly 'devel-opment Lake Susan residents previously expressed their objections to the developer proposing multiple and high density dwellings adjacent to the Planned Industrial Development and Lake during the industrial development public hearings. II. The proposed development will cause extreme traffic congestion for the Chanhassen road system, especially, T.H. 5 & 101 and County Road 17. A. According to the Minnesota Department of Transportation (Mn/ DOT) District 5, no monies or plans have been made to upgrade either of these state 'highways; yet the bulk of the development will be using these roads as main arteries, increasing an already frustrating congestion problem on the roads, particularly on T.H. 5 and 101. The developers report states that T.H. 5 traffic will be "manageable in 1990. Those of us who commute along this route know that it is not being managed in 1980, and that it is not uncommon to experience frequent and long delays. Con- struction of signals on County Road 17 will increase trip times -2- for those desiring to travel T.H. 5 to the eastern major centers and downtown business .areas if they unfortunately live to the west of the proposed signalized intersection -in Chanhassen or if they live in neighboring western communities. Chanhassen residents who commute to major eastern employment centers are experiencing increased trip time due to Eden Prairies' addition of intersec- tions and signals for development. We believe that Chanhassen's first priority within its territorial jurisdictions is to assist Mn/DOT in assuring that trunk highways remain functional. Present T.H. 5' traffic volumes warrant a four lane facility with channelized intersections. The 1990 volumes shown in the report warrant a.four lane divided facility with controlled access. -The number -of cross or intersecting roads' -will continue to increase with development in both Chanhassen and Eden Prairie, further complicating transportation problems. The developers report shows a 60 percent projected traffic increase in T.H. 5 in twelve years. We believe that the density and financial success of the proposed development depends on the construction of T.H. 212. At the present time, no monies are available for the construction of the highway and the project development process is .in the infant or scoping stage. A recent article in the Chaska Herald, by the County Engineer, indicates the seriousness of the funding problem and points to continued deferment and delays in roadway projects. Also, Dunn and Curry's.report only mentions the traffic pattern for County Road 17, yet much of the development will enter onto T.H. 101 which is not geometrically designed to handle the traffic and will potentially be dangerous to all residents living and travel- ing on Hwy. 101. B. The development proposes :in,umerous cul-de-sac and curvilinear local roads. Few of the local streets are through streets. This type of roadway network or development will force local or short trips to use the major roadway networks increasing the number of turns and further inhibiting through traffic movement. The proposed Lake Susan Hills Planned Residential Development, based on the - 3- developers' projections, will generate at completion over 11,000 trips per day. Many municipalitiesarenow discouraging cul-de-sac layouts due to.winter maintenance problems. C. An industrial park does not necessarily mean that the people moving into -Chanhassen will work in the community. Jonathan is.a case in -point. It is not a self-serving community as it was projected to be. Thus, the industrial park will only increase traffic,. -not reduce traffic. The multiple dwellings units will attract young wage earners to this development. There will be limited localemployment for this one particular segment of the working class, and the majority of these new residents will be-forced,to-commute to the major eastern employment- centers. This situation is similar to Apple Valley where housing is cheaper south of -the river; yet most of the residents must commute to northern employment centers, forcing extreme traffic congestion along the interconnecting highways. III. An environmental assessment worksheet (EAW) will not be completed until June, after the city public hearings on the development. No plan should be approved until an EAW has been evaluated. At that time, the EAW should be reviewed and if further study is warranted, an environmental impact study (EIS) should be conducted. A. We are concerned that the density of this project would have a detrimental effect on the quality.of the lakes, adversely affect or reduce wetlands, and destroy many natural wooded areas. 1. Lake Susan contains an unusual lotus lily (Wild Lotus Nelumbo lutea) that is an endangered plant species and is protected by both federal and state regulations. 2. It is a natural habitat for many forms of wildlife such as wild geese, heron, ducks, piliated woodpeckers, raccoon and deer. -4- 3. Development may have an adverse effect on the water quality of'the,lakes. The use of deicing salts on the numerous local -streets will increase .the concentration of these.sal.ts in the lakes. An anticaking agent used in conjunction with deicing salts has been found to produce cyanide in some area lakes. The nutrient.load, nitrogen and' phosphorous, should also be -expected to increase from grassy area fertilization and irrigation. Retention ponds equipped with skimming devices will not remove these soluble substances. The intense development will result in greater human usage and occupation of the lakes. -Bacteria counts from this -intense -use could easily reach a magnitude preventing body -contact. recreation in these relatively shallow and low volume lakes. The Lake Susan South Development shows the developers ponding system outletting into a low or swampy area that is presently -privately owned. Will the residents City of Chanhassen be forced to acquire this ponding area in the future, or should the developer be forced.to purchase it now? 4. We are also concerned that the holding ponds and drainage systems will not be adequate during a heavy rainstorm or an event greater than the design frequency and will overflow, releasing pollutants and silt into the lakes. Special care is also needed to prevent lake pollution and siltation during construction. IV. Dunn and Curry state that their development will generate tax revenue. This is misleading in that they fail to consider the "hidden costs" of development. This development will actually increase our taxes and assessments. The following questions need to be addressed before any development is approved. -5- ■ A. With the total population increase of 1,174 children, will this mean additional schools? B. Will we now need a full time police force in Chanhassen? C. Will we need a full time fire department and additional fire stations? D. Will we need increased city employees for the extended services? 1. Who will maintain the dedicated open space or parkland? 2. Who will be responsible for the upkeep of the additional roads? 3. Who will pay for the needed capital water utility improve- ments, such as well fields, water storage and pumping and treatment plant? 4. Who will maintain the additional water distribution and sanitary sewer collection systems? 5. Who will maintain and operate the retention ponds needed by the developer? (Chanhassen presently has 15 full time employees and a population of 6,300 compared to Eden Prairie which has 90-100 full time employees and a popula- tion of approximately 15,000. Chanhassen's projected population after the completion of this proposed development and Chaperal is approximately 15,000.) E. Will we need more public buildings to house additonal city employees?- F. Will other existing property owners be assessed for water, sewer, and roadway improvements that may result from the indirect impact of this development? Will water main looping be required outside of the project area to insure adequate water pressure and volume to the development? Will sanitary sewers and roadways also be required outside of the project area to support the development? We suggest that if these indirect improvements are needed, the developer be required to pay a major portion of the cost. Existing residences with on -site water and/or sewer systems will and should expect a salvage valve reduction from any proposed assessment. It is important to remember that there must be benefit in order to assess. IM M- _11J al. 1 u i sect iy and i u i rec 1y, present taxpayers wi i i have to support these increased services created by this development. These are the concerns that the residents of Chanhassen feel should be addressed by the City Council before any development is approved around Lake Ann or Lake Susan. -7- MR- 0 cc / T m C j L �.. ,, C4 CO c0�— CO IL w Q m 79 Fm� •• m 'W ca 3 tom=mU�ttwC�H X 0 i Q as itn a) 4- co O Q1 s c v, -.— Z +' Cl) 4-3 +3 Q to cn � T i.

We do not feel that it is in the best interest of the community to have apartment buildings and other multiple dwelling type housing adjacent to the lake. This type of development would have a very pronounced degrading effect on our property values, and would create many hidden problems. As you know, the city of Minneapolis has gotten National recognition for its good planning. One of the most notable things is the way the lake shore was developed. The majority of the lakes are surrounded by open space, then sin�--le dwelling housing. The Lake Ann development appears somewhat consistent with this planning technique. However, the Lake Susan plan is not consistent with what is "Nationally known" as good planning. In all due respect to apartment dwellers, they would not have a vested interest in the upkeep of the lake and therefore the taxpayers would have to finance a park maintenance crew to maintain the premises. We urge you to consider single dwelling on all lake shore with the open space dedicated to the home owners association, which would put the maintenance burden on the home owners. This is the simplest and most effective method. Behind the single dwellings a buffer zone and then multiple dwelling would be the most proper way of developing. As was mentioned during the phase one planning meetings, we do not feel the community is ready for this type of development because of the current road system which is inadequate and would create an undue hardship on nearly all the Chanhassen residents that travel to and from the Metro area. tiT ( a RECEIVED ) �l VILLAGE OF \�P .= CHANHASSEN, cj�SG� MINN.i - 2 - We can understand the contractors interest in getting the highest return on his investment, but it should not be at the residents perpetual expense. We sincerely appreciate your consideration of our views and feel confident that your judgement in this matter will be for the best interest of the City of Chanhassen. In summary, we feel that serious consideration should be given to the following items: 1. Much lower density on the property surrounding the lake. 2. The road system. 3. Environmental impact. 4. Cost of maintenance to the city. 5. School system needs.

Today, I again confirmed the fact that the Metro Council does not, in any way, pressure, dictate, or insist upon the type of homes in areas of new developments. They do encourage a variety of homes, including multiple dwellings, but do not insist upon any multiple family or other high - density situation such as proposed by Dunn & Curry. They have.no objection to a new development of single family homes situated at two units per acre, as long as it is approved by the Planning Commission and City Council and abides by local ordinances. They repeatedly stressed the facL that the type of homes in new developments remain the prime responsibility of local officials. Respectfully, Mrs. M. M.

The small opening in the face of the control structure will provide the only outlet for the pond, up to a 100-year storm. The grate on top of the structure will provide additional outlet capacity for a storm in excess of a 100-year frequency storm or for protection should the small opening get clogged. This restricted outlet will cause retention and sedimen- tation to occur in the pond area. LAKE OUTLETS The outlet structures at the lake will be used to dissipate energy and reduce flow velocities to prevent erosion of the lake shoreline. This will be accomplished by one of the following methods. First, the high velocity flows will be _directed into a manhole where the flow will fall down and into a larger pipe at a relatively flat grade. This manhole will dissipate energy in the flow and the large pipe will reduce the velocity. Second, a concrete block structure will be constructed at the end of the'high velocity pipe. The flow will hit the concrete block which will dissipate the energy and reduce velocity. Both methods will also utilize rip -rap at the outlets to help control erosion.

Based on the documentation provided by Mr. .Callahan relative to the numerous reviews of your plans by the Commission, we have concluded that additional review by the -Commission is not warranted at this time. According to City records, the proposed park locations indicated on the most recently revised development plans are in accordance with the recommendations of the Park Commission. Therefore, additional review would serve no purpose unless you wish to revise these plans. You should keep in mind, however, that the issue of park dedication and park fees is yet to be resolved through discussions with the City Council, as provided by City ordinance. A copy of Fran Callahan's memorandum, tome concerning.the. Park and Recreation Commission's review of your development. plans is enclosed for your information.. If you disagree with this information or have any questions or concerns relative to this matter, please do not _..., hesitate to contact me. :. Sincerely, k . 1 Scott A.

Box 147' Chanhassen, Mn. 55317 Dear Mayor Hobbs: I am pleased to inform you that Chanhassen's System Statement is being formally submitted to you today, under separate cover. I am particularly pleased that the informal negotiation process which we have been using to reconcile disagreements seeded to prove sound and workable in Chanhassen's case.. My staff has advised me that a constructive dialogue was estab- lished with your city staff and that the informal negotiation pro- cess has taken place in a spirit of good faith and cooperation. It appears that this process has resulted in a substantially improved system statement for your community. Your city pl-anner,.Bruce Pankonin, has requested that I clarify the wastewater industrial flow projections contained in.the system statement. I am happy to do so. Industrial. flow is defined as being that flow used for manufacture and which is over and above the domestic wastewater generated by -- employees -of the industry. The domestic flow from employees is accounted for.at the employees' dwellings and is included in the ' domestic flow projections. Only if a city has industry with little. or no residential development would any adjustments have to be made for domestic flow generated at an industrial facility. Secondly,. whether an employee works in one city or another has little. effect on the projections because conditions tend to average out based on residential domestic forecasts. �oti�2�23 11 15i MAY 1977 RECEIVED �l+1ttAitFi��s • � 1��l1�� g L� An Agency Created to Coordinate the Planning and Dejvelopment of the Twin Cities ivletro1) litaa. ,om}prising Annkn C:+?unty n Cnrvnr Con+�L•y n 17nkotn County � Hannr+T+i� ::onnty C� Rnm�w Cnnn[}• +� Fc-ntt Rn+mr�• +� lVnoT+it+rC[nn �nr;rt� April 28, 1977 Page 2 The 1990 industrial flow of a community estimated in a system statement is based upon several factors. Zoning and/or local plans (such as the recent Chanhassen plan amendment) were not used in the calculations, since we were primarily concerned here with the capacity,of our wastewater treatment plants to treat industrial sewage. Local plans and zoning are perfectly valid considerations in sizing both local and metropolitan sewer. They are not. of any particular help in sizing treatment plants. The reason for this distinction is that a sewer line is laid down to serve the ultimate, or 50-year, planned use of a service area regardless of how much of that facility's capacity will be used by 1990 or 2000. On the other hand, a wastewater treatment plant is sized to adequately treat wastewater flow projections for only 15 years. "A treatment facility can be expanded to provide for additional capacity when needed at a future date_ Therefore, a local government which plans and/or zones for major industrial development and builds large sewer lines to serve that development may not be assigned large industrial wastewater flows for planning purposes in its system statement. This does not mean that a local government would not be granted a revision of its wastewater flow projections by the Metropolitan Council and I-R4CC if an industry were to locate within the local government's boundries Sewer Service District No. 4 had an industrial flow of 560 MGY in 1976. The 1990 industrial flow is projected to be 810 PIGY. This is approximately a 45% increase for the service. area. Most local governments within the service area have substantial areas zoned or planned for industrial development. Sanitary sewers can be designed for such development without much change in sewer installa- tion cost. However, if sewage treatment plants were to be built to handle ultimate planned flow, plants would be very large and very costly. Further, only a small fraction of their capacity would be used for many years. There is real doubt that such a large plant would function properly with the initial flows. Generally, there is adequate industrial flow capacity _provided in one municipality or another of a service area. This capacity may be transferred from one local government to another as the need arises. One factor which is of increasing concern to us is the need to up- grade wastewater sludge. By reducing or eliminating problem wastes, sludges can be a resource rather than a continuing regional liability that requires costly disposal. Whenever undesirable substances such y April 28, 1977 Page 3 as lead, cadmium or similar heavy metals are introduced into the wastewater flow, they tend to settle out in sludge and make it undesirable for use as a fertilizer or soil conditioner. This is another reason for keeping the industrial flow allocations low. It will encourage additional communication between local govern- ments and the MCC, providing the latter with some opportunity to review industrial flow proposals and evaluate prossible impacts to the system. It is my hope that this information will assist you in your evalua- tion of your system statement, and that we can continue to work amicably together in reaching mutual understandings on such important issues. cc: James Daly Donald Ashworth Bruce Pankonin JB; jc Sincerely, hn Boland airman METROPOLITAN COUNCi- Suite 300 Metro Square Building, Saint Paul, Minnesota 55101 METROPOLITAN SYSTEM STATEMENT CITY OF CHANHASSEN Issued to the City of Chanhassen April 28, 1977 I, John Boland, Chairman of the Metropolitan Council, do hereby certify that the attached Metropolitan.

The projections were made beginning with a forecast for the entire seven -county Area. Total areawide forecasts were then stepped down to smaller geographic areas, ending with forecasts for local governmental units. The forecasting methodology is described on page 60 of the Development Frarnework chapter of the Metropolitan Development Guide. The forecasts are not precise in the sense that they necessarily will be attained in the year shown. Rather, they should be viewed as guides which express the anticipated pattern of regional development. The Council is using these figures for planning metropolitan facilities. A certain amount of variation in community growth from the forecasts is natural and should be expected. The amount of.va_rlation that is consistent depends upon a number of factors. For communities in the Area of Planned Urbani- zation rapid growth in excess of the forecasts would be a problem only if there is not enough capacity in metropolitan facilities to accommodate it. Slow-grov.rth or no -growth plans could be a problem if they preclude reason- able urban growth from being accommodated in the sector or create too much growth pressure on neighboring communities. The Council's major aim is for the sum total of local plans to accommodate the region's urban growth in a manner that can be served by existing and planned _metropolitan systems, without overloading them. The Urban Service Area on Map 0-2 will accom- modate regional growth in the most economical way. Substantial variations between local growth assumptions and those listed here should be discussed and resolved early in the planning. process. e projections were made in 1973. Since 1973, birth rates and household formation rates have continued to show slower Metropolit-an Area growth than anticipated. Because of this, the Metropolitan Council will re-eETaivate these, forecasts this year to see whether changes are necessary. L'your community is affected by a significant change, yeu w� t be no.tifie I of it, Viand of any resulting changes in met*-opolitan system plans. The household projections generally indicate the number of housing units expected to be needed to house future resideats in Your comauni t?y. The factual need for additional housing units. includes not only growth in house- Xholds, but also new homes which may be.needed to replace housing removed �xdue to aging, blight, and disasters. The household projectio 6s for your _ communi*- .7 assume, the provision of housing for a broad range of het:sahcld � � incomes. _ In planning Chanhassen's role in the provision. of housing units, you should be aware that the Metropolitan Land Planning requires that each local comprehensive plan must specifically provide for sufficient existing and new housing to meet the community's share of the regional need for low and moderate income housing. The plan must further contain an implementation program for carrying out the .� housing objectives. O - 2 - APR 2 8 "!977 • Metropolitan Council policies emphasize planning for the provision of subsidized housing.for low and moderate income persons as well as the provision of modest cost market -rate housing. To assist in achieving- these A objectives, your housing implementation program should include programs C3 for providing subsidized housing as well as codes and ordinances that. aermit the construction of modest cost market -rate housing. Your plan should also identify the need for rehabilitation and redevelopment of substandard p� housing, if this is appropriate for your community. The plans and programs proposed by your community will be reviewed for consistency with Metropolitan Council adopted housing plans and policies.

TRANSPORTr1TION The information in this section is derived from the Metropolitan Transportation Development Guide/Policy Plan adopted by the Metropolitan Council in January, 1976 and information obtained from the Minnesota Highway Department. The Council's Policy Plan should be consulted when Chanhassen prepares the transportati element of its comprehensive plan. This plan sets forth policies for how metropolitan an ortation facilities should be use and further develope pa icu ar zrrportar_ o Chanhassen wz e e policies focusang on transportation within the Urban. Servic Areal including the Area of Planned Urbanization, and within the Rural Service Area. Highways The Transportation Policy Plan describes a functional classification system for use by all counties and municipalities in the metropolitan area (Tables A 1 and A 2). Those roads which function as principal and intermediate arterials are considered to be the metropolitan highway system (Map A 1) . The following portions of the metropolitan highway system lie within transportation planning subregion 4 or the adjacent rural area and affect the City -:of Chanhassen: TH 212 (Existing) fromm CIt 18 to Dell road Character TH 212 is a 4-lane divided freeway with .fully controlled and access from CR 18 to I-494.

Safety and other minor improvements , which are not normally reviewed by the Metropolitan Council, may be made. Transit The Metropolitan Transportation Plan assumes that transit and paratransit will play an increasingly important role in the regional transportation system by augmenting the capacity of the metropolitan highway system. To underscore this, the regional highway. system has been planned for a vehicle occupancy of 1.6 perso ns. per vehicle in 1990 compared with 1.4 in 1970 in the peak hours. The Transpbrtation Policy Plan contains a conceptual 1990 transit plan consisting of two parts --service within sub- regions and express service to the Metro Center (Map A 2) . A specific transit plan for the metropolitan area, applying these concepts to actual service, will be prepared by the Metropolitan Transit Commission by the end of 1977 in its Development Program. The urbanized portion of Chanhassen is in transportation planning subregion 4. The existing transit service in these subregions, which has not been analyzed for its consistency with•the Policy Plan, is shown on Map A 3. Existing bus service (routes and schedules) is not fixed, and Chanhassen is encouraged to work, with the MTC in changing this service, if necessary, to meet the objectives of the Policy Plan. There are no major fixed transit facilities existing or planned in Chanhassen.. General Planning Considerations The capacity of the 1990 Metropolitan Highway System as planned in the Transportation. policy. Plan is based upon the population, household, and employment projections cited earlier in this system statement. These projections indicate that there will be a total of about 97,800 person trips beginning or ending in Chanhassen on a typical day in 1990. All of these trips will use the local, collector and/or minor arterial system within Chanhassen for at least a portion of the trip. Some of these trips will - 8 - APR Z 31W7 use this lccaliz::d system only to :=a h the mecrop Titan system. However, over half of the tri. = '.:'it : eri.gins or destlnatiors in sucreglcz 4, which includes Chanhassen, remain within the same subregion for the entire length of the trip. The Metropolitan Highway System is not planned to carry these subregional trips. The Transportation Policy Plan assumes that Chanhassen in conjunction with neighboring municipalities and the county, will plan an adequate system of local streets, collectors and minor arterials to accommodate all of these trips. A map of the functional classification system in Chanhassen, as adopted by the Metropolitan Council and its Transportation Advisory Board, is attached for your information (Map A 4). Map A 4 is taken from a seven county map which was prepared by all the county engineers in 1975 through the auspices of the transportation plan— ning program. Requests for revisions of this map should be ad— dressed to the Transportation Advisory -Board. Additional informa- tion about these facilities may be obtained from the agency of jurisdiction. To analyze the impact of Chanhassen's land use plan on the Metropolitan Highway System, the Council will need to receive population, household, and employment data from Chanhassen by traffic assignment zone at the time the city's comprehensive plan is submitted for review. A map of traffic assignment zones will be sent in.a later communication. An issue which Chanhassen should address in its plan is the future of TH S, a minor arterial.

AIRPORTS .The information in this section is based on Minnesota Department of Aeronautics . Rules and Regulations. The existing Airports chapter of the Metropolitan Develop- meng Guide contains a plan for a system of airports in the metropolitan area, but due to recent changes in air travel demand and airport needs, the chapter will be revised during 1977. When a new Airports chapter is adopted by the Metropolitan Council, information about the planned airport system that may affect Chanhassen will be sent to you. If the information is forwarded to you before January 1, 1978, it must be reflected in your comprehensive plan, as stipulated in Section 6 of the Land Planning Act. Facilities There is no airport, proposed airport site or search area, or aviation related facility located in Chanhassen (Map B1) . Planning Considerations Even though there are no aviation facilities located in Chanhassen, any development affecting navigable airspace within the community is subject to Minnesota Department of Aeronautics regulations Aero 9 (Criteria for Determining Obstructions to Air Navigation) . In addition, under MDA regulations, Aero 13 '(Seaplane Operations) the surface water of Lakes Minnewashta and Riley has been designated for seaplane operations (Map B2) .

WASTE MANAGEMENT Information in this section is based upon the Waste Management Policy Plan/Development Guide, the Metropolitan Waste Control Commission's 1977-81 Development Program, and the MWCC Capital Budget. The Devel- opment Guide should be consulted when Chanhassen develops the sewer element of its comprehensive plan. Of particular importance to Chanhassen will be the Guide policies related to waste management in the Urban and Rural Service Areas. Metropolitan Interceptors and Treatment Plants According to the most recent information available from the MWCC, the 1976 annual domestic flow for the City of Chanhassen was 134 MGY (or an average of 0.37 MGD). Due to a holdback and storage of industrial wastewater by the Gedney operation during the last year, the actual industrial flow from Chanhassen in 1976 was zero (0). Total 1976 wastewater flow for the City (domestic plus industrial), was therefore 134 MGY. The MWCC Engineering Department has calculated for planning purposes that the.unit flow (gallons per capita per day) for Chanhassen in 1976 was approximately 81 g/c/d. This figure yis based upon such factors as average daily flow, amounts of inflow-ir infiltration into the local system, low.flow, peak flow, and other factors. The 1990 wastewater flow projections were generated using the Council's 1990 population forecast for Chanhassen modified, after review of the City's most recent CSP to locate population concentrations and probable areas of growth consistent with the Development Framework plan, to arrive at an estimated 1990 'sewered' population. This estimate is -based upon the 1974 population forecasts of the Council, and may be changed to reflect new forecasts presently being prepared by the Council. The 1990 sewered population for Chanhassen is currently forecast at 16,700. An increased wastewater flow (unit flow) was calculated for all local governments whose units flow in 1976 was less than 100 g/c/d. Past water use records have shown that increased water consumption has occurred at a rate of approximately , g/c/d per year. The 1990 unit flow for the City of Chanhassen has therefore been projected to be approximately 88 g/c/d. The 1990 domestic flow for Chanhassen (sewered population x unit flow) is projected to be approximately 536 MGY, or an average of 1.47 MGD. `'All of,the 1990 domestic flow is anticipated to be treated at the Blue Lake WWTP. Industrial flow - means only that flow used for manufacture and which is over and above wastewater generated by domestic use of employees of the industry. At this time, 'Chanhassen should plan on -an industrial flow of not more than 35 MGY, or an average of 0.1 MGD in 1990. This fore- cast provides for Chanhassen's intent to develop a 300-acre industrial park in.the Lake Ann service area. - 20 - The Council and the Me,:ropolitan Waste Control. C _nission (M WCC) will use these population and sewage flow forecasts to plan for all future treatment works or interceptors needed to serve your community. Chanhassen must through its comprehensive planning process decide the I ocation and staging of development and then design its local collection_ system to serve 'this development. If you plan a total community flow in excess of 1.57 mgd, your assumptions will be analyzed by the Council for their possible adverse effects upon the metropolitan disposal system. Adverse effects would include constrictions in. downstream interceptors, overload of lift stations or treatment plants, impact on planned flow from neighboring communities, and other conditions. In the following descriptions of -metropolitan interceptors, the ultimate capacity available to your community in a particular inter- ceptor may not be stated, because it has not been determined yet. It will be determined in the course of a 201 Facilities Planning Study being undertaken by the MWCC and scheduled to be finished in 1979. Ultimate capacity in an interceptor is difficult to determine due to_ various constrictions in downstream sections of the metropolitan inter- ceptor system and the use of the same interceptor by a large number of communities. In developing your community's plan, you should contact the Council or the MWCC concerning capacity available to you in specific interceptors. ' Map C-1 shows the location of metropolitan facilities serving your community. Shorewood II Interceptor MSB-7017 (Existing) Character and The Shorewood II Interceptor is a forcemain and gravity flow Location interceptor sewer which flows eastward between the Victoria Interceptor MSB-7019-A and Shorewood I Interceptor MSB-7016 . The interceptor runs eastward from a lift station immediately northeast of Lake Virginia; then northeastward roughly paralleling the Minneapolis and St. Louis Railroad alignment then -along the Trunk Highway 7 alignment to Covington Road. The Covington Road alignment is followed southeastward to the connection with Interceptor MSB-7016 at Townline Road. Between the Lake Virginia and the E:ccelsior lift stations the in+-erceotor chances from a 24 inc�, diameter forcemain to . gra,trity flow through a 24 inch, then 30 inch diameter rein- - forced concrete pipe. From the Excelsior Lift Station effluent is routed through a 24 inch diameter forcemain to the inter- section of Trunk Highway 7 and Coviny on Road ­, mere the inter- ceptor changes to gravity flow through a 30 inch diameter reinforced concrete pipe. APR 2 8 1977 Four extensions of the interceptor project southward from the main portion: a) A 12 inch diameter reinforced concrete pipe gravity facility flows between Christmas Lake and Silver Lake from the Chanhassen boundary and the Shakopee Inter- ceptor. b) A combined gravity and forcemain facility flows north from the Chanhassen boundary along Christmas Lake Road through a 15 inch diameter reinforced concrete pipe to a lift station, then through a 9 inch polyvinyl chloride pipe and an 8 inch ductile iron pipe to the major inter- ceptor . c) A 9 inch diameter polyvinyl chloride forcemain runs. from the Cha nha s sen boundary along the west shores of Galpin and Mud Lakes to the major interceptor. d) A 15 inch diameter reinforced concrete pipe gravity facility flows northeastward from Pleasant Avenue at the Chanhassen boundary along the northwest side of Mary Lake to the major interceptor. Function The Shorewood II Interceptor provides metropolitan interceptor sewer service for 898 acres in northern Chanhassen as well as for Waconia, St. Bonifacius, Minnetrista, Laketown Town- ship,. Victoria , and the communities along the southern and western shores of Lake Minnetonka. Timing The facility is in place and is currently in use. Capacity The exact ultimate capacity of this interceptor and when it will be available are dependent upon downstream conditions of the interceptor or available capacity at the treatment plant. The 201 study previously mentioned will provide some of this information. Chanhassen Forcemain MSB-7025-1 & 2 (Existing) Character and This combination gravity flow and forcemain system begins at Location a lift station on the Carver County side of the Carver -Hennepin County boundary between Trunk Highway 5 and Rice -Marsh Lake. The forcemain runs north along the county boundary to Trunk - 22 - .APR 2 8 1X7 Highway 5, then east along the highway to Westgate Road. From this point it runs north to Town Road and then east to the Purgatory Creek Interceptor, with eventual treatment at the Blue Lake Wastewater Treatment Plant in Shakopee. From the beginning at the lift station to a point north of Mitchell Lake on Highway 5 the facility is a 161" forcemain. From that point to connection with the Purgatory Creek Interceptor it is a gravity flow pipe increasing from 18" to 30" at the Purgatory Creek connection. Function The interceptor provides metropolitan interceptor sewer service for portions of Chanhassen and Eden Prairie. Effluent treat- ment is ultimately provided at the Blue Lake Treatment Plant. Timing The facility is in place and is now in use. Capacity The exact ultimate capacity of this interceptor and when it will be available are dependent upon downstream conditions of the interceptor or available capacity at the treatment plant. The 201 study previously mentioned will provide some of this information. Lake Ann Phase I Interceptor (MSB-7138 (Existing) Character and The Lake Ann Phase I Interceptor sewer serves Chanhassen Location in the Rice -Marsh Lake and Lake Susan vicinity. The inter- ceptor is a gravity sewer and is the first of three phases. constructed for the Lake Ann, Interceptor sewer system. The interceptor flows east, beginning at Trunk Highway 101 and extends approximately 3,000 feet to the Chanhassen Lift Station. Function -The interceptor provides metropolitan interceptor sewer service for that part of Chanhassen lying in the Riley Creek Watershed area. At completion, it is planned to provide sewer service for the surrounding communities of Mound, Minnetrista , St. Bonifacius, Victoria and other areas which have their sewage pumped through the Lake Virginia Lift Station. The Lake Ann Phase I Interceptor sewerage floyU is transported to the Blue Lake Sewage Treatment Plant by way of the Purga- tory Creek Interceptor in Eden Prairie. Timing The interceptor is in place .and now in use. - 23 - APR 2 8 197-7 Capacity The exact ultimate capacity of this interceptor and when it will be available are dependent upon downstream conditions of the interceptor or available capacity at the treatment plant. The 201 study previously mentioned will provide some of this information. Lake Ann Interceptor, Phase II (Planned) Character and The Lake Ann Phase II Interceptor would extend westerly and Location and northwesterly from the west end of the Phase I pipe to the vicinity of the southwest corner of Lake Ann and there terminate. The area of service is all within the Urban Service Area and the Riley Creek Watershed. Function 'fine Lake Ann Interceptor is part of the long-range permanent sanitary sewer service corridor for the Lake Virginia pumping station and upstream service area consisting of all communities around the western one-half of Lake Minnetonka. Timing Lake Ann Phase II -is included in the Waste Management Policy Plan as a project for the MWCC's 1977--81 Development Pro- gram; the Policy Plan stated it should be considered for construction in the 1977 to 1980 time period. In its 1977-81 Development Program, the MWCC stated that further consi- deration of the timing -of construction should be based upon' the completion of the 201 facilities plan on Lake Ann described below. The Council approved this timing in its review of the Development Program and the MWCC 1977 Capital Budget. As noted in the Budget review by the Council, by following the planning and budgeting process set out in the Policy Plan and the Metropolitan Reorganization Act; constrsction of Phase II should be completed by the end of 1980 Chanhassen Area Service Needs (To be Studied) Character and Chanhassen is presently provided sewer service primarily. Location through Phase I of the Lake Ann Interceptor. Phase Ii, an extension of the interceptor, is to be included in the Com- mission's first development program. Additional study is needed to determine the timing of further extension of the Lake Ann Interceptor to provide a relief outlet to the Shorewood Interceptor system north of Chanhassen. Timing The study is included in the Wastewater. Management Chapter of the Metropolitan- Development Guide and is part of the MWCC's 201 facilities planning program. It is scheduled to be undertaken in 1977. _ - 24 - APR Z 8 W7 Pla ,ning The Wastewater Management Policy Plan cequires an Considerations update of Chanhassen's comprehensive sewer plan prior to construction of Phase II of the Lake Ann Interceptor. The city of Chanhassen should work closely with the MWC.0 and the Metropolitan Council in the preparation of their CSP revision and to determine the timing of interceptor construction. Blue Lake Treatment Plant (Existing) Character and The Blue Lake Metropolitan Wastewater Treatment Plant is Location an activated sludge plant. It is located in the city of Shakopee just north of Highway 101. It discharges to the Minnesota River. Function The Blue Lake Plant provides primary and secondary treatment for sewage flow for communities in sewer service area 4 on the westside of the Metropolitan Area. This facility, in particular, was built to phase out local treatment plants that discharged into Lake Minnetonka. Capacity The current design capacity of this facility is 20 mgd . Current flow to the plant from its service area is almost 10 mgd: - The plant is estimated to reach design capacity at or about 1990. Conditions on There currently are no limitations on a community's flow to Use the Blue Lake Plant that are attributable to plant conditions. However, there is potential for future interim limitations until I sludge disposal facilities at the plant are put into operation. General Planning Considerations On -Site Disposal It is very important for Chanhassen to specify in sufficient detail in its comprehensive plan how its regulatory system for inspection, monitoring, and maintenance of on -site sewage disposal systems will be implemented and enforced so that the Metropolitan Council can be assured that premature sewer service will not be required in the rural service area . Proper installation, regular maintenance, and effective monitoring of on -site sewage disposal systems are local government responsibilities but there has been great variation in the effec- tiveness of local regulation among the 190 local governmental units in the 25 - AFIR 2 a W7 Metropolitan Area. The Minnesota Pollution Control Agency is presently in the process of developing standards for on -site disposal systems. Even with the adoption of these standards, however, local governments will still have the responsibility for professional inspection of the installation, monitoring ground- ;vater quality, and educating the homeowner on the proper use and maintenance of the system. The Metropolitan Council's position is that all municipalities and counties in the Metropolitan Area should incorporate the MPCA regulations in the sewer element of their local comprehensive plans, utilize the plan and MPCA standards in the issuance of permits, and establish an on -going inspection and information program on the use of on -site disposal systems. Stormwater Collection and disposal of stormwater runoff is a matter of concern to developed, urbanzing, and rural communities alike. In the preparation of a comprehensive plan, the city of Chanhassen should address stormwater runoff in a manner consistent with the plans and policies of the Riley --Purgatory, Minnehaha-Creek, and Lower Minnesota watershed districts and the Water Resources Chapter of the Metropolitan Development Guide.

RECREATION OPEN SPACE The information- in this section is based on the Metropolitan Recreation Open Space Development Guide/Policy Plan adopted by the Metropolitan Council in December of 1974. This Policy Plan is available as a guide as the City of Chanhassen develops the Parks and Open Space component of its comprehen- sive plan. Metropolitan Facilities Minnewashta Regional Park (Planned) Character This is a 400 acre regional park. Location The proposed park is located on the northeast side of Lake Minnewashta in the City of Chanhassen, Function It functions as an area of natural quality for nature oriented outdoor recreation such as viewing and nature study, swimming, picnicking, boating, and hiking. Its service area includes parts of sectors 7, 8 and 9 as identified on page 16 of the Rec- reation Open Space Policy Plan. Capacity Information is not available at this time. In reviewing Car- ver County's Master Plan for regional parks, the Council re- quested -that capacity information be provided as an amend- ment. We expect this information in the near future. Timing of Property acquisition and development is planned according to Future- the Council's adopted Capital Improvement Program, when Improvements funds are available. Planning Carver County has completed a master plan for this park which. Considerations has been reviewed and approved by the Metropolitan Council. The master plan should be consulted to determine the specific locations of activities, access points, parking, buildings, etc. planned for the park. Chanhassen should be aware that the master plan makes no provisions for local or neighborhood recreation facilities to be located in the park. Therefore, the city should not plan to rely on the regional park to help meet local playground needs. The primary responsibility for policing and protecting the park property lies with Carver County, unless other arrangements have been made between the county and the City of Chanhassen.
