Box 21199 Eagan, MN 55121 RE: Carriage Green Phase II - Pond Schematic Dear Mr. Vraa: I am forwarding to you two copies of our proposed improvements to the pond located at the southeast corner of Yankee Doodle Road and Lexington Avenue. The Pond Schematic incorporates trailways, benches and physical fitness stations. Our land- scape architect has estimated the proposed improvements at approximately $90,000. The final improvements will become more definitive as we secure cost estimates. Since changing this area from an unkept water collection de- pression to an improved asset to the community, the pond will be a significant asset to the City of Eagan. As such, we request from the City of Eagan the following: 1. Waiver of our park dedication fee. 2. A commitment from the city to maintain this area once the improvements have been completed. Kindly submit the Pond Schematic and this letter to the Advisory Parks and Recreation Committee for their consideration. Ve,r°y truly your. your, STUART CORPO P C: Leralc' Sov 'Il ,.,ice P-esident :BLS: jk Enclosure CITY OF EAGAN SUBJECT: PRELIMINARY PLAT (STUARTS 2ND ADDITION) APPLICANT: STUART CORPORATION LOCATION: NW 1/4, SECTION 14 EXISTING ZONING: R-4 (MULTIPLE) DATE OF PUBLIC HEARING: MAY 26, 1987 DATE OF REPORT: MAY 19, 1987 REPORTED BY: PLANNING & ENGINEERING APPLICATION: An application has been submitted requesting a Preliminary Plat for the Stuart 2nd Addition. This 9.2 acre, 1- lot plat will contain a 102 unit rental apartment building located east of Lexington Avenue and south of Yankee Doodle Road. The Carriage Hills Condominiums are to the east and the Stuart lst Addition (Carriage Green Apartments) are to the south. i. proposal is in conformance with the November 1986 Land Use EXISTING CONDITIONS/SITE PLAN: The first phase , buildings received final plat approval in 1986 and are already 60% occupied. The proposed 3-story building is the same as the existing ones that have a brick and redwood gabled exterior. A large ponding area will separate the buildin from Yankee Doodle Road. There will be an approximate 35' dift;' between the water level and the first floor elevation. Th. applicant intends to develop this area for passive recreational use and a landscape architect has been retained to do the design work. A variety of hardwood trees are found in the lower areas, especially. on the eastern hillside. Selective thinning will visually enhance this area as well as the health of the trees. Mature oaks along the top of the hillside by the Carriage Hills Condos will not be disturbed, The 102 units give this project a gross density of 11.1 units/acre. All building/parking setbacks meet Code requirements. The applicant will include one covered parking stall with the rent and provide one additional exterior space. The exterior stalls are shown with 9' widths. The Fire Marshall recommends that a 10' wide bituminous mat be extended from each end of the parking lot around the north side of the building to the swimming pool area for emergency access. Knock down bollards could be placed at parking lot/drive intersections. The conceptual landscape plan is well done showing a mixture of plant material, sizes and species. It will be finalized incorporating the park like setting of the area to the north and the existing plantings of the first phase creating overall compatibility and consistency in this high density area. GRADING/DRAINAGE: This development will be located on the south side of the existing drainage basin located in the southeast corner of Yankee Doodle Road and Lexington Avenue. There is a maximum 40 foot elevation differential from the intersection of Golview Drive and Lexington Avenue to the drainage basin bottom. Subsequently, this development will consist of a "walk out" complex constructed into the side of the hill adjacent to Golfview Drive. The revised plans dated May 5, comply with the City's minimum slope requirements. The westerly driveway entrance should be constructed to create a high point to contain the gutter drainage within Golfview Drive right-of-way. The proposed parking lot in the vicinity of Golfview Drive and Lexington Avenue is approximately five feet below the first floor elevation and 12' below Golfview Drive. This results in the requirement for a retaining wall from the parking lot in front of the major entrance to the facility. It is recommended that this corner of the parking lot be raised 2-3 feet to minimize both the retaining wall next to the major entrance and the side slope requirements adjacent to Golfview Drive. The final grading plan must show the proposed future grades of Lexington Avenue to insure compatability. Preliminary review by the County Soil and Water Conservation District indicate minimum problems associated with this development provided a satisfactory erosion and sediment control plan is prepared in accordance with City standards and closely followed during construction phases. All runoff generated from this proposed development will be conveyed by an internal storm sewer system to the drainage basin within this site. The existing trunk facilities and drainage basin are all adequately sized to handle the increased runoff proposed from this development. UTILITIES: Sanitary sewer and water of sufficient size, depth and capacity are readily available within Golfview Drive to provide immediate service to this development. No additional trunk and/or lateral utility constructions are anticipated. The internal lateral storm sewer system will connect to the existing trunk storm sewer system, minimizing the amount of additional construction disruption. The trunk storm sewer facilities have adequate capacity to handle the additional runoff generated from this development. STREETS/CIRCULATION: Access to this development will be provided by two intersections on Golfview Drive opposite the existing driveway intersections for the Stuart's 1st Addition on the south side. No access is proposed from Lexington Avenue as it will be restricted by the County. Golfview Drive is in its final stage construction to its ultimate design section. However, it is recommended that the final surfacing be delayed one more year to allow substantial completion of this proposed development. fi n ~ ~ ~ IF GENTRL _ e' °~'N Kp In r N- 1~0 11 1 p°LEARY PAR ~C CARRIAGE HILLS COLFj 2 Z r. ¢ BLUE .KY cVRSE ° a..,ol ..nuu~a - . f&~.aH 4 - 4 - I 4 A ms's L Rnao G EA ,F All I R-4 L7 CPD CSC 1 p D-1 ~ v I. ~ t I IQ II D-1 PIE D`11 N 097'92 E 724 62 L 0` S~ ba fj,' ,y C K i :4 °oa f 4 0~ 111 \ LJ CJ 'f' J :Y: ~E° R$ E i _ ' 1 ~'x° ~E R g z ~ 2 flThflI!TTssEcoNDAITIoNL - „ p flHiII,inc. p®K STUART CORPORATION PLANNERS / ENGINEERS / SURVEYORS OUTLOT D, TOMAMK :RD ADDITION.

This plat consists of 2.8 acres. The applicants propose a private school for grades K-6. Total enrollment is expected to be 300 at capacity. The issue for the Advisory Commission is to determine whether the school, as a private institution, is subject to a parks dedication fee. As Commission members know, public schools have been subject to a parks dedication requirement, but the requirement has been waived until such time as the school reverts to any use other than a public school. The site planning for the school does provide for a play area, a hard court play area and an open play space. The play area is not of sufficient size to provi e for ball field space, but does provide for open field games. The Plan ping Department has also required the developer to provide proof of parking should the school building ever revert to a commercial office site. This proof of parking is contained within the packet information. FOR COMMISSION ACTION To provide a recommendation to the City Council regarding the parks dedication requirements for the Golle Welsh Addition, a preliminary plat fur a private school. Respectfully submitted, Director of Parks & Recreation KV/js CITY OF EAGAN SUBJECT: CONDITIONAL USE PERMIT/PRELIMINARY PLAT (GOLLE WELSH ADDITION) APPLICANT: GOLLE WELSH LOCATION: NW 1/4, SECTION 31 EXISTING ZONING: LB WITHIN WINKLER JACKSON P.D. DATE OF PUBLIC HEARING: MAY 26, 1987 DATE OF REPORT: MAY 19, 1987 REPORTED BY: PLANNING & ENGINEERING APPLICATIONS: Separate applications have been submitted requesting a Conditional Use Permit to allow a private school in a Limited Business District and a one-lot Preliminary Plat consisting of 2.8 acres for the Golle Welsh Addition located between Slater Road and the Cedar Avenue entrance immediately south of the Amoco Service Station. The proposed building was designed to accommodate all LB setbacks and parking requirements should the private school use ever change. Proposed. Outlot A (1.4 acres) will be tc the north and Outlot B (3.6 acres) will be south of the school facility. No amendments to then Winkler Jackson Planned Development will be necessary. The applicants hope to open the school to students in early September 1987. Since this building cannot be completed in time, the owners will also request a Special Permit to allow temporary modular buildings on the LB land south of this plat until the permanent building is completed. The anticipated date is January 1, 1988. These modular buildings will be similar to those used at Northview Elementary School. City utilities will serve these buildings and crushed rock will be used in the parking areas. ,,:Asphalt will be required for the access drives and must meet the Engineering Department requirements. PRIVATE SCHOOL: This facility is designed to accommodate 300 children at capacity. However, the intent is not to overcrowd, with a maximum of 22 per class. The first year will limit enrollment.to 150 (70 3 & 4 year olds and 80 K-3rd grade). The second year will expand to K-6th grade. The school will be fully regulated by State Educational Agencies. The staff will be certified and eventually consist of a full time administrator, director of school, 11 teachers - 11 aides grades K-6, 7 preschool teachers and speciality teachers on a limited basis. The school is primarily for families with above-average income and for children demonstrating above average intelligence. Individuality and the use of progressive learning techniques and equipment will be stressed. The 170-185 day curriculum will be reviewed by the state. Year-round school will be provided if desired. The hours of operation will be 6:00 a.m. - 6:00 p.m., much the same as a day care facility. Each student will have parental drop off and pick up. No bus service is provided. Daily traffic generation will be greater than an office type use. The following is an approximate projection. 352 ADT 21,000 sf office (16.8 trips/1000 sf) 750 ADT 300 student private school (2.5 trips/students-,staff) SITE PLAN: This building meets all LB requirements for coverage, parking (proof for 116) and setbacks. The trash enclosure and roof top fan units will be incorporated into the stucco or masonry walls. Metal bands and the roof will accent the main structure. Colors should be decided prior to final approvals so the building aesthetically blends in with the residential property to the west. Access will be provided by a one-way, south to north drop off area with 28 staff and visitor parking stalls. The entry drive provides stacking for 10 additional vehicles. Proposed Winkler Jackson Park on the northeast corner of Slater Road and James Street, approximately 1/4 mile south, is scheduled for development in the next couple of years. It will contain an open field/ball field area that would provide active recreational needs for this proposal. An off-street pedestrian connection should be provided to the park. The preliminary landscape plan will need to be upgraded with the final plat submissions to meet current City policy requirements. No problems are anticipated. GRADING/DRAINAGE: The proposed site consists of open grassy sloped topography with elevation differentials of 30'+/-. The development proposes to fill most of the site with minimal areas of excavation. The greatest fill section is located at the northeasterly corner of the site. The development proposes to use a retaining wall in this area to prevent the fill slope from encroaching onto the northerly adjacent property. Staff advises against the use of a retaining wall. Elimination of the retaining wall would require the development to obtain a slope easement from the adjacent property owner. The fill in the northeasterly corner of the proposed site blocks the southeasterly directed natural drainage across this site and creates a landlocked lower area on the adjacent northerly property. A retaining wall is also proposed in the southeasterly corner of this site. Staff also advises against the use of the retaining wall at this location. This site proposes to convey its storm water runoff to the existing storm sewer in Slater Road. The existing storm sewer in Slater Road does not have sufficient capacity to handle the runoff generated by this development. Due to the topography of the proposed plat, storm sewer will be required to be extended to Outlot A and Outlot B. UTILITIES: Sanitary sewer service and water main of sufficient size, capacity and depth are readily available along Slater Road. The development proposes to jack under Slater Road to make the water main connection. This is not necessary because an existing 6" water main has been stubbed to the proposed development. The development will be responsible for the necessary adjustments of the existing sanitary sewer manholes caused by the proposed site grading. STREETS/ACCESS/CIRCULATION: Access to the proposed site is readily available from Slater Road. The development proposes to take access from Slater Road in two locations. The development will coordinate its site access locations with the proposed Oak Cliff Pond development on the westerly side of Slater Road. RIGHTS-OF-WAY/EASEMENTS /PE ITS: No additional right-of-way for Slater Road is required as a condition of final plat approval. Additional easement width is required for the existing sanitary sewer along the westerly side of the proposed development. The development will be responsible for the appropriate storm.sewer easements. No regulatory agency permits are anticipated beyond the City's required permits for utility service hook-up. ASSESSMENTS: The proposed site has been levied the following assessments at the single-family rate: Water area, water lateral benefit, storm sewer trunk, sanitary sewer trunk, and Slater Road street improvements. Storm sewer has been assessed at the upgraded C/I rate. There are no pending assessments and the developoment will be responsible for the following assessments as a condition of final plat approval: DESCRIPTION PROJECT RATE QUANTITY AMOUNT Water Main Lateral Benefit 275A $ 8.08/ff 656.71 ff $ 5,306 Slater Road Upgrade 275A 46.93/ff 656.71 ff 30,819 Water Area Upgrade 254 1,900.50/ff 2.8359 ac 5,530 TOTAL $41,655 The final assessment amount will be determined using rates in effect at the time of final plat approval and based on final plat dimensions and areas.

Several other calls have been received also inquiring as to "what," "where," and "when" of a park in this neighborhood. Attached is a letter from Mr. Liebermann. At a recent meeting with Mr. Liebermann, the suggestion of a neighborhood informational meeting was discussed as being beneficial. Mr. Liebe nn also wanted to invite Mr. Willmus to a meeting in hopes of trying to negotiate scme type of early park land dedication, and for the City to then proceed with development. The Planning Department has been requested to provide update on the Willmus property and any time frame commitments previously made. This information will be important for any neighborhood meeting. Staff is asking direction from the Commission as to whether a neighborhood meeting should be held to inform the residents of the City's Parks Plan or if a letter would be just as good. Staff does not believe it would be of any value to have Mr. Willmus at any public meetings to discuss any type of early parks dedication. For Commission Action: To recommend to the City Council a course of action - to hold a neighborhood meeting, send out an informational mailing or to respon o Mr. Leibermann with a letter.

A tot lot was a condition of preliminary plat approval by the Advisory Parks & Recr~eat.on Commission. The reason Rosewood Corporation was requesting this requirement. be removed is that the owners now occupying the units did not wish to have a tot lot installed, preferring the open space. Further, there were no significant numbers of children within the development, making the play equipment useless. At that meeting, the Commission requested that Rosewood Corporation complete or conduct a survey of the homeowners individually to determine if they wished to remove the tot lot from the master plan. Staff has received original letters signed by 53 of the 80 homeowners at Four Oaks Court requesting and identifying them as being in favor of removing the tot lot. A cover letter also indicated that additional letters may be supplied at the Commission meeting on Thursday evening, representing those who have not yet responded. FOR CO SSION ACTION To either remove the requirement of the tot lot from the requirement of the Four Oaks Development or require the installation of the tot lot as previously required. Respectfully submitted, Director of Parks & Recreation KVljs MEMO TO: ADVISORY PARKS RECREATION COMMISSION KEN VRAA, DIRECTOR OF PARKS RECREATION FROM: THOMAS A COLBERT, DIRECTOR OF PUBLIC WORKS DATE: JUNE 1, 1987 SUBJECT: WATER QUALITY MANAGEMENT PLAN HOC COMMITTEE The Public Works Department is in the process of preparing a Water Quality Management Plan which was conceptually presented to the Parks & Recreation Commission in 1986. At the present time, we have completed an inventory of all 340 wetlands and lakes within the City. The next step is to proceed with a classification system to identify the proper intended uses of these various wetlands and lakes ranging from recreational body contact to nutrient and sediment trapping. Once all these wetlands and lakes have been classified, specific water quality standards will be identified. Then various sampling and ongoing monitoring will take place to verify the existing condition in relationship to its classification requirements. This will help identify various capital improvements and related costs to help the City identify and establish long range capital improvement projects. The City would like to establish an ad hoc committee to help clasify these lakes and wetlands and identify appropriate water quality standards for the various classifications. Because the Parks & Recreation Commission has expressed interest and concerns in the past, it would be appreciated if this Commission could designate an official representative to sit on this committee. I am enclosing a copy of the news release that will be published in the local newspaper soliciting other citizen participation and explaining the purposes and duration of this committee. I would appreciate it if you would give this serious consideration by designating a member of your Commission to participate in this important management plan preparation process. If you like additional information, please let me know and I will be happy to provide further details. Director of Public Works TAd j j Enclosure NEWS RELEASE Are you concerned about the quality of water in your backyard pond? or are you concerned about the quality of water in Eagan's lakes so that they are swimmable and fishable? The City will determine how neighborhood ponds, wetlands and lakes will be used with the assistance of a citizens committee. The City has placed a very strong emphapsis on citizen involvement as the decisions to be made will determine how clean all neighborhood ponds will be. All lakes and ponds in the City of Eagan will be classified into different use catagories. Some ponds will be classified as recreational basins, others as sediment or nutrient traps or stormwater storage areas. The waterbody classification system will be a major component in the Water Quality Management Plan. The Management Plan is unique in that it will combine the expertise of the City, the Soil and Water Conservation District, a water quality consulting firm and the local Citizens Committee. The MPCA and DNR will also be invited to participate during the planning process. The role of the Citizens Committee will be to: 1. Identify specific water quality issues in Eagan. 2. Adoption of a waterbody use classification system for 340 wetlands and lakes in Eagan. 3. Establish a specific use for each identified waterbody in Eagan. 4. Approve water quality standards for each classification. 5. Adopt and implement a water quality sampling program to begin the summer of 1987. 6. Resolve use conflicts that arise during the planning process and as the city continues to develop. 7. Adopt a Water Quality Management Plan for City Council approval. The Water Quality Management Plan will outline specific practices the City must follow to insure Eagan's waterbodies are used for their identified use. The Citizens Committee will meet beginning in June. Approximately 8 evening meetings during the next year are needed to adopt a final Water Quality Management Plan. Involvement is needed by local citizens for this plan to be a plan for the residents of Eagan. Now is your opportunity to help determine how the City's wetlands and lakes will be managed. If you have an interest in serving on this committee or would like additional information, contact Tom Colbert at 454-8100 or Brian Christensen at 463-8626.

Attached is another update and summary of expenditures. The information in this summary differs from the October format in that you have not been provided with any cost estimates for remaining work contemplated under the 1984 Bond Improvement Fund Project List. Staff will be providing new cost estimates for remaining work with the next report due later this year. This report deals primarily with expenditures "to date" by program ;park) and year. Expenses through April and encumbered funds for Contracts 87-7 and 87-13 are shown. Staff would expect to provide the Commission with a comprehensive report of work completed, work in progress, work remaining, and revised costs estimates for remaining work with the next report. Staf will be able to respond to Commission questions regarding the fund and expe it es at the Commission meeting. Directofo Parks & Recreation Attachment KV/mc BOND .REFETNEXM E.

CITY OF G SUBJECT: PRELIMINARY PLAT - CRAY ADDITION APPLICANT: CRAY RESEARCH, INC LOCATION: OUT TS H, I, J, L, LONE OAK ADDITION, SECTION 1 EXISTING ZONING: PD/PLANNED DEVELOPMENT DATE OF PUBLIC HEARING: MAY 26, 1987 DATE OF REPORT: MAY 21, 1987 REPORTED BY: PLANNING & ENGINEERING DEPARTMENTS APPLICATION: An application has been submitted requesting a Preliminary Plat for the Cray Addition. This replat of Outlots H, I, J, and L of the Lone Oak Addition consists of one 3G.2 acre lot for multiple office building use and nine outlots totaling 80.2 acres east of Lone Oak Drive and north of Lone Oak Road. This proposal is consistent with the Planned Development Agreement. BACKGROUND: The 452 acre Lone Oak Addition has four major landowners: Cray Research (116.4 acres) and Northwest Airlines (156.4 acres), with the remaining area split between Wachovia Development and Laukka Development. The Laukka Beck Planned Development had a number of reviews by the City with the racetrack proposal in 1984. An Environmental Impact Statement was completed for the entire 452 acres. An Indirect Source Permit was also obtained for the same area. All requirements of the Minnesota Pollution Control Agency (MPCA) have been met to date. The total square footage approved for the entire development is 3,141,000 sq. ft. with an additional 1,000,000 sq. ft. that could be added between the years 2005 and 2020. SITE PLAN: Access to this site will be from a singular connection to Lone Oak Drive. The single access is requested for security reasons. This road will eventually be constructed along the perimeter of the first phase development, creating a large looping system. Flexibility in the final layout is important so there is compatibility with the building design requirements. Cray is proposing private streets designed to City standards so that they can be dedicated to the City in the future. This will not occur until the entire ring road is completed. The development concept is to create a campus-like setting much like the 212 acre Sperry (Unisys) site that has more than one building on a lot. Platting property in this manner requires greater park dedication and assessment obligations than if individual buildings/lots were created. Cray understands this and is willing to meet all City requirements. The initial development will consist of an approximately 70,000 sq. ft. computer center and one or two 40-60,000 sq. ft. office buildings. The architects and engineers have been selected and building plans are in the design process. The City will require that these plans be reviewed by the Council prior to any building permit issuance. Cray is proposing a staging plan with this proposal so that all affected parties have a basic understanding of the ultimate design. There has been considerable attention given to the existing topography and vegetation in an effort to create a development of the highest quality. GRADING/DRAINAGE: The site is rolling and is separated into 3 drainage basins. Approximately 1/3 of the site drains north to Pond FP-4.1 and FP-E which for the most part are included in Lone Oak 2nd Addn. while 1/10 of the site will drain east to Pond FP-8. The remaining portion of the site will drain southwesterly to Pond FP-7 included on the Wacovia property. The outlet for Pond FP-7 is in place and was constructed as part of Lone Oak Addition. The storm sewer outlet for Pond FP-E and FP-4.lare required as part of Stage 1 development and will be directed to Pond FP-7. The outlet elevation for Pond FP-4.land FP-E shall be constructed in accordance with the City. Pond ease- ment shall be dedicated to the HWL for Pond FP-°E and FP-4.1 included in Cray Addition. The overland flow to Pond FP-4.1 from the wetland in the northwest corner of the site shall be conveyed in pipe. The drainage area directed to Pond FP-3 is included in Stage 2 development. However, Pond FP-8 is not in- cluded in the Cray Addition. Therefore, when Stage 2 development does occur, the storm sewer outlet for Pond FP-8 to FP-4.lshall be required. The required easements for the storm sewer to Pond FP-8 and the storm sewer outlet from Pond FP-8 to Pond FP-4.lshall be the responsibility of this development. The grading of the site is confined only to the roadways as presented on the plan. Therefore, a review of the on-site grading shall be required prior to approval of this development. The grading of the roadways impacts one wet- land which propose filling half the wetland (approx. 0.5 acres). The grades of the roadways appear to be within the percent of grades required by the City of Eagan. UTILITIES: Sanitary sewer to serve the Cray Addition will be provided from the trunk sewer in Lone Oak Drive. A requirement of Stage 1 development is to connect the trunk sewer in Lone Oak Drive to the sewer in Lone Oak 2nd Addn. through Cray Addition. The sanitary sewer in the northerly part of the looped street shall be constructed to an elevation to properly serve the property along the north side of Pond FP-8 located to the east. Therefore, it is rec- ommended the sewer be lowered approximately 8" from that proposed and be stubbed to the east line of Cray Addition having an invert elevation of ap- proximately 873. Cray Addition shall be responsible for its share of the san- itary sewer extension easterly in Lone Oak Road from Lone Oak Drive to the east line of Cray Addition. Water main serving the Cray Addition will be provided from the 16" trunk main in Lone Oak Drive. To provide proper looping of trunk mains, Stage 1 de- velopment shall be required to connect the 12" trunk main in Cray Addition to the existing 12" trunk main in Lone Oak 2nd Addn, located at the north line of Cray Addition. Stage 2 development shall be responsible for providing a 10" water stub to serve the property to the east. The 16" trunk main in Lone Oak Road from T.H. No. 55 to Lone Oak Dr. is not required for Stage 1 development due to the looping provided through Lone Oak 2nd Addn. However, due to the nature and value of the development in the Cray Addition and in Lone Oak 2nd Addn, it is recommended this 16" main be constructed within the next two years, Cray Addition shall be responsible for its share of the water main ex- tension in Lone Oak Road from Lone Oak Drive to the east line of Cray Addition in accordance with City of Eagan Standards. STREET/CIRCULATION: Cray Addition is proposed to be served by one street con- nection onto Lone Oak Drive. Due to the significant counts at the one street connection (17,460 ADT) consideration should be given to providing two connec- tions onto Lone Oak Drive dispersing the traffic. This would also eliminate the anticipated congestion projected at the connecting street with the looped street. The impact of this development to Lone Oak Road (Co. Rd. 26) should also be considered as to when Lone Oak Road should be considered for upgrading. RIGHT-OF-WAY/EASEMENTS/PERMITS: This development shall dedicate all required utility and ponding easements located outside of dedicated public right-of-way within the Cray Addition as a part of final plat approval. Ponding easement dedication shall be in accordance with the requirements of the City's Compre- hensive Storm Sewer Plan and any subsequent revisions necessitated by detailed review of this development proposal. This development shall acquire all related regulatory agency permits in a time frame according to their requirements. ASSESSMENTS: Trunk area sanitary sewer has previously been assessed over the entire area of this development proposal. However, trunk area storm sewer has only been assessed over the west 60% of this development. Therefore, the additional assessments will be the obligation of this development as follows: ITEM QUANTITY RATE AMOUNT PROJECT # Trunk Area Storm Sewer 1,418,414 sf1 $0.079/sf $112,055 302 Trunk Area Water 36.2 ac 3,170/ac 114,754 447 1Area in southeast quarter of Section 1. Only those trunk area assessments associated with Lot 1, Block 1, are calculated for this proposed development. The obligation of the remaining outlots of this development will be due at the time of their replatting. All final assessment obligations will be calculated based on final plat dimensions and rates in effect at the time of final plat approval. CONDITIONS: 1. The development agreement shall be entered into and approved by the City allowing multiple buildings on a single lot. 2. The applicants agree to review each site plan for specific buildings with the City Council at the time of building permit. 3. Outlot A shall be designed in accordance with the public street standards and, also, setbacks from Outlot A shall be required in accordance with public street requirements. 4. Detailed landscape plans shall be submitted with each application for building permit. 5. The Preliminary Plat shall be subject to the Park Commission's recommendations and comments. 6.

LOCATION: NE 1/4, SECTION 31 EXISTING ZONING: R-3 WITHIN WINKLER JACKSON P.D. (82-3) DATE OF PUBLIC HEARING: MAY 26, 1987 DATE OF REPORT: MAY 19, 1987 REPORTED BY: PLANNING & ENGINEERING APPLICATION: An application has been submitted requesting a Preliminary Plat for the Oak Cliff Pond Addition. This plat consists of 42 owner-occupied detached townhouses on the eastern 9 acres (or Outlot C) of the Oak Cliff Addition. The original P.D. Agreement called for a maximum of 311 housing units on the west side of Slater Road (5.5 dwelling units x 56.56 acres). When the Oak Cliff Addition was approved on March 22, 1984, Condition #2 stated that the new density for ,that area would be 231 units. The Oak Cliff Addition was approved for 75 single family lots and 9 twin home lots (93 total units) leaving the potential for 138 units on the remaining 22 acres. This would have approximately 6.3 units/acre, consistent with the R-3 Townhouse zoning district. The remaining undeveloped portion of the original Outlot B was then platted into Outlots B and C west and east of the large pond, respectively. A 50-unit townhouse proposal was approved in concept only on new Outlot B but never had formal approval. In April 1987, 3 twin home lots were rezoned to R-1 which raises the. allowable total number of units west of Slater Road to 141 (138±3). The subject 9-acre 42-unit plat (4.7 units/acre) on Outlot C will leave the potential for 99 units on Outlot B (7.6 units per acre). If that area was platted to the subject plat density of 4.7 units/acre, there would be a reduction of 38 units (61 on 13 acres). SITE PLAN: The existing vegetation consists of native hardwood trees and understory material on most of the site that falls toward the large ponding area and open grass land on the north centeral area along Slater Road. The grading plan E'roWs an overall design , but the applicant is requesting flexibility in the house pad locations and deviations from strict Code setback requirements in order to save trees wherever possible. Retaining walls were also suggested, but the locations cannot be shown on a detailed basis until individual lots and the proposed building footprint are studied together. More than one building style will be used. The footprint shown is to demonstrate average building size and grading feasibility only. 30' building setbacks from the R-2 land should be retained to provide privacy for both projects. 40' building setbacks will be required along Slater Road unless approved otherwise. Most are shown approximately 30' and act as sideyards for this development. Private street front yard setbacks of 25' minimum and 20' on cul-de-sacs have been maintained. These buildings are designed in a zero lot line manner; one exterior wall of a unit will be directly on the property line. Through careful detailed site planning, courtyard/private spaces can be achieved for each unit. An association will maintain common areas and trash pickup. GRADING/DRAINAGE: The proposed site consists of partially wooded rolling topography with elevation differentials of 36 feet The low point of the site is the normal water level of the westerly adjacent pond designated as Pond AP-l0 in the City of Eagan's Comprehensive Storm Sewer Plan. The high point of the site is along the south property line adjacent to the Oak Cliff Addition. The proposed grading plan attempts to maintain a 30-75' undisturbed area along the easterly side of the pond. No grading is proposed below the high water level contour. Also, Outlot B and Outlot C of the proposed plat are designated as undisturbed areas. The proposed grading of Lots 3-6, Block 2, has a major impact on the existing topography. The backyard grading of Lot 6, Block 2, exceed the maximum allowable 3:1 slopes. The proposed house pad elevations of Lots 2-13, Block 3, are below the proposed street grades. This can cause water problems from storm water runoff into the garages. The storm water runoff from the proposed site is intercepted by an internal storm sewer system and discharges into Pond AP-10. This pond is designated in the City's Comprehensive Storm Sewer Plan to receive runoff from the development. The internal storm sewer system as proposed is inadequate to handle the runoff generated by this site. Submission of appropriate storm sewer calculations are required for proper sizing of the storm sewer system. UTILITIES: Sanitary sewer and water main of sufficient size, capacity and depth have been stubbed to the proposed site from the existing facilities in Slater Road. The internal sanitary sewer system as proposed in the area of Lots 1-13, Block 3, is not of sufficient depth to serve the proposed walk out pad elevations. The internal loop water main system will provide adequate water pressure to serve the development but the hydrant coverage as proposed is inadequate. STREET/ACCESS/CIRCULATION: Access to the proposed site is readily available from Slater Road. The development proposes to take access from Slater Road in two locations. The development will be required to coordinate its entrance locations with the proposed Golle Welsh Addition along the easterly side of Slater Road. The development proposes to accomplish the internal traffic circulation by the use of private streets. City Code requires the width of the private street to be 30' back to back of curb. The centrally located cul-de-sac will have a 45' minimum radius with a 26' width back to back of curb. RIGHT-OF-WAYS/EASEMENTS/PERMITS: No additional right-of-way for Slater Road will be required as a condition of this development. The proposed Outlot D will serve as a utility easement and access to the existing storm water lift station. The development will be responsible for providing the appropriate storm sewer easements. No unusual permit requirements are anticipated beyond the normal Department of Health permit for water main extension and the Minnesota Pollution Control Agency permit for sanitary sewer extension. ASSESSMENTS: The proposed site has been assessed for the following items at the single family rate: sanitary sewer trunk, water area, storm sewer trunk, Slater Road street assessments and water lateral benefit. The proposed site has also been assessed at the multi rate for storm sewer upgrading. There are no pending assessments and the following are proposed as a condition of final plat approval: Description Project Rate Qty. Amt. Slater Rd Street Upgrade 275 $31.09/F.F. 1095.5 $34,059 Water Main Lateral Benefit 275 $ 8.08/F.F. 1095.5 $ 8,852 Total $42,911 The final assessment amount will be determined using the rates in effect at the time of final plat approval and based upon final plat dimensions and areas.
