Adjournment MEMO TO: ADVISORY PARKS AND RECREATION COMMISSION FROM: KEN VRAA DATE: DECEMBER 1, 1986 SUBJECT: DECEMBER 4 COMMISSION MEETING As a reminder, the Commission will be meeting at Trapp Farm Park shelter rather than at the Eagan Municipal Center. After the approval of the agenda and minutes of the meeting of November 6, 1986, the first items to be reviewed are the various development proposal before the Advisory Commission. I. Diffley Center Addition The proposed shopping center of approximately 91 acres at the intersection of 35E and Diffley Road. The proposed shopping center complex consists of 735,000 square feet which would include a Target store and a Northwest Swim and Raquet Club as first phase development. Also planned in the first phase, as it relates to parks, the developer is proposing to provide a public recreation area of. approximately 8.4 acres. The developer has indicated that this public use area would be provided to the City "in addition to the normal parks dedication requirement." Further, it was indicated the developer will allow the City two years to review this to determine if it wished to make use of this public use area before final acceptance. The developer has suggested that this might be suitable for a community center /ice arena in that overflow parking could be accomplished on any of the adjacent commercial areas. However, the parcel could be used for any public recreation purpose. The Advisory Planning Commission reviewed this item on Tuesday, November 25 deferring action until their January commission meeting. II. Lone Oak Second Addition Lone Oak Second Addition is a proposed Northwest Aerospace Training facility. As with all items, the Planning Department's packet is included concerning this item. Staff is recommending a cash dedication requirement for this addition. III. Both the Manor Lake Addition and Stafford Place Additions have been reviewed by the Planning Commission on its November 25 meeting and have been continued at the request of the developers. There is no action necessary on behalf of the Advisory Parks and Recreation Commission on these two items. IV. Staff has received the submissions for the Eagan joint venture /Chuck Hall property which proposes dedication of specific parkland parcels. Staff will be meeting with the developer on Monday, December 1 to review these submissions. This item has been placed on the commission agenda for informal review by the Advisory Commission. Because of the size of this PUD, the Advisory Commission may wish to again reactivate the development committee to work with staff in review of this proposed parkland dedication. OLD BUSINESS I. There are three items under Old Business. Item 1 is a review of the City Code. Enclosed are member's comments which have been retyped. II. Director of Public Works Tom Colbert will be present at the Commission meeting to review storm sewer plannings as it impacts parks. Director of Parks and Recreation and Landscape Architect /Parks Planner met with Mr. Colbert to generally review some of the concerns of the Advisory Commission which Mr. Colbert will address on Thursday. III. The final item under Old Business is the Park Naming Committee which should be called together to begin developing official name suggestions for several existing parks. NEW BUSINESS I. Staff is expecting reductions of the Comprehensive Trails Plan to be reviewed by the Commission. If received by the Commission meeting, this item will be placed on the agenda. Staff has incorporated the suggestions for revisions made at the last commission meeting and expect this trails plan to resent the most up -to -date plan of existing and proposed future trails. This trails plan should be received and approved for inclusion into the parks systems plan. II. DEMOGRAPHIC PROFILE Intern Julie Lenkowski will present the report on the demographic profile by parks service areas and service districts. Julie has spent a considerable amount of time in reviewing 1980 and 1985 census data in developing this demographic profile. Members will note that is it very similar to the parks systems plan as prepared in 1982. With approval of the commission, this section will then be reproduced and submitted as part of the updating of the parks systems plan. III. The third item under New Business is the Parks Systems Plan updating. The Commission has annually reviewed the parks systems plan for the purposes of updating those sections which are in need of review. With the work by Julie Lenkowski and the review of the trails plan, these two sections are among will be current. Further, the City has already undertaken the study of its Water Management Plan and staff does not feel it's necessary to update the Pond and Lakes section. Members may wish to review other sections for updating. Staff will be reviewing and updating the Inventory and Analysis section. IV. Recreation Supervisor Dorothy Peterson and Paula Sunder will provide a brief report on the winter programs and activities planned during the winter season. Both staff members have been extremely busy with these planning activities as well as other responsibilities associated with their positions. V. At the time of this writing, the video presentation of the Parks and Recreation Department is in the final stages of editing. A copy of the video presentation will be available for play at this commission meeting. PARRS DEVELOPMENT Under parks development, staff will provide you with an update and status report on the current activities for parks development. Generally speaking, the early snowfalls in November seriously disrupted the completion of the park grading contract and its punchlist items. Work is continuing, however, on the park shelter facilities. OTHER BUSINESS AND REPORTS Two items under other business and reports include the community center study which is set for January 10. Staff has been in contact with representatives from the cities of Eden Prairie, St. Louis Park and Brooklyn Center who have agreed to provide tours of their facilities on Saturday, January 10. A time frame and committment should be firmed up, so final arrangements can be made with these communities. Enclosed for your review is a report from Park Superintendent John VonDelinde to the Director of Parks and Recreation concerning revisions to scheduled maintenance for winter facilities. This proposed maintenance program takes into consideration the variables of staffing as a result of snowfalls and the priority system for classifications of rinks. If there are no other business items, a Roundtable discussion by the Commission of will be in order followed by Adjournment. Respectfully submitted, Ken Vraa Director of Parks and Recreation KV /cks A regular meeting of the Advisory Parks and Recreation Commission was called to order by Chairman Martin at 7:05 P.M: Members present were: Porter, Alt, Masin, Martin, Thurston, Bertz, Caponi, Kubik. Absent was Commission member Ketcham, who was ill. Staff present were: Director of Parks and Recreation, Ken Vraa; Parks Planner /Landscape Architect Stephen Sullivan; Planner, Jim Sturm; Student Intern, Julie Lencowski. Other visitors were present for specific agenda items. AGENDA MINUTES OF REGULAR FETING OF THE ADVISORY PARKS AND RECREATION EAGAN, MINNESOTA NOVEMBER 6, 1986 Chairman Martin asked to have added to the agenda the setting of a date to visit the parcels being proposed for development by Mr. Hall and Sienna Corporation. Director of Parks and Recreation Vraa, asked that under "New Business Item #5 Trails, be added. There being no further additions, a motion by Thurston, seconded by Carroll, with all members voting in favor, the agenda of November 6th was approved. MINUTES OF SEPTEMBER 4, 1986 Chairman Martin noted several typographical mistakes for correction. It was noted that under "Round Table Item C" the word "collected" should have been inserted after the words "additional dollars Motion by Alt, seconded by Masin, with all in favor the September 4th, 1986 minutes were approved as amended. 2 Adv. Parks Rec. Comm. November 6, 1986 MINUTES OF THE MEETING OCTOBER 2, 1986 Commission Bertz moved, seconded by Kubik, with all members voting in favor that the minutes of October 2, 1986, be approved as presented. In the minutes of the Special Meeting, October 6th, member Carroll corrected the Waldron spelling. A motion by Carroll, seconded by Kubik, with all members in favor, minutes of October 6th as amended, were approved. Chairman Martin noted that Planner Jim Sturm was not present at this time, and moved that the Commission discuss Item #1 under "New Business Eagan Hockey petition. COMMUNITY CENTER PETITION Mr. Robert Smith, President of the Eagan Hockey Boosters, presented a petition representing approximately 250 signatures of Eagan residents. Mr. Smith said, the petition was collected to show the City Council and Advisory Commission the interest within the City for developing a Community Center. He went on to state that the petitioners felt that the City of Eagan needed a Community Center to service existing needs of the City, and as the City continues to grow, these needs will only expand. He indicated that many residents were tired of travelling to Burnsville and Rosemount to make use of facilities. He indicated that nearly $13,000 of ice time was purchased from other arenas, as skaters must go to other communities to skate or swim. He stated that the names on the petition represented mostly those interested in hockey and swimming. Roger Martin then explained to Mr. Smith the existing information concerning a community center and the recent Commission formation of a Study Committee. Mr. Smith, in response to a question, stated that he felt that School District #196, identified primarily with Rosemount, and not Eagan, was a major factor for people gravitating towards Rosemount in the use of their facilities. He felt that Eagan needs a recreational hub, and a community center would fulfill that need. Chairman Martin questioned if the petition represented the interest of the general population or if it was strictly "hockey interests Mr. Smith responded, that he felt the petition represented Eagan Hockey Club, but also included others interested in swimming and a community center in general. Mr. Martin said, that he felt the petition was a good inventory tool, and felt there were other recreation and social concerns for a community center, which the City must study. After additional discussion, and a motion by Kubik, seconded by Carroll, with all in favor, that the petition be accepted from the Hockey Association, noting that the City Council has directed the Commission to prepare a first phase study. STORM SEWER STUDY Adv. Parks Rec. Comm. November 6, 1986 Chairman Martin noted that this item was deferred to December, as a result of Mr. Colbert's required attendance at the City Council meeting, which was held simultaneously in the Council Chambers. CITY CODE REVIEW Roger Martin explained, that each individual has a responsibility to review those sections of the City Code pertaining to parks. He then inquired as to where the "Parks Dedication" is in the City Code? Director Vraa replied, that within the zoning section, references are made to the requirement and certain dedications for parks purposes, which are then spelled out by the City policy. Commission member Thurston questioned whether the Commission will be made aware of any City code changes and updates, as well as revisions. Director Vraa responded that, as the City code book is updated, the revised pages would be sent to the Commission members. After additional discussion, Chairman Martin suggested that the Commission submit their reviews in writing to the Director of Parks and Recreation regarding issues pertaining to parks in anticipation of next month's meeting. Such memorandums could then be compiled and sent to the Commission with the packet. November 24th was established as the deadline date to have these into the Director's office. COMMUNITY CENTER STUDY The Director of Parks and Recreation presented a list of existing facilities to the Commission for further review and refinement, as potential facilities to visit. He indicated the Commission should consider dates for visits, which facilities to visit, and add any other facilities not mentioned. Jo Anne Alt questioned, what the difference was between a first and second generation ice arena, which the Director responded to. George Kubik questioned what the Staff's top five facility prorities were? The response was: St. Louis Park, Brooklyn Center, and Eden Prairie, as being three of the top possibilities on the list. Bogert Martin said, he wished to go to the three sites, as mentioned. Sandy Bertz concurred saying, she felt these three facilities were very important to visit. After additional discussion, the Commission decided on the second Saturday in January (January 10th), in which to make visits to the sites. Director of Parks and Recreation was requested to mail out questionnaires to these community centers and set up meeting times. 3 4 Adv. Parks Rec. Comm. November 7, 1986 SNOWMOBILE TRAIL USE REQUEST Director of Parks and Recreation, Ken Vraa, presented the request from the Eagan Snowmobile Club as requested by Mr. Maynard Ohm. He stated that this was a request for a fourth or fifth season. Chairman Martin questioned if there had been any problems in the past year. The Director responded that, the only problem was that the people do not stay on the designated trails, and go on to parks, specifically Walnut Hill, Trapp Farm, and Rahn school sites. Martin asked if the Snowmobile Club could do an additional job of policing, would the use continue? Sandy Masin questioned, if it was possible to find out if the snowmobile abusers are within the Snowmobile Club. Jo Anne Alt commented that most of the use was along the Highline Trail, in which more and more homes were being built adjacent to it. She indicated that snowmobiles along the trails do not mix well with residential development. Roger Martin concurred that more and more people are living along the Highline Trails, and if the snowmobiles are abusive they do not work together. After additional discussion concerning various problems, on a motion by Kubik, seconded by Martin, with eight members voting in favor, and one "no" vote, the Commission recommended to the City Council approvals to use Highline Trail Corridor and Johnny Cake Ridge Road as corridor for access to the Dakota County Trail System as in previous years. The Commission further went on the record to express concern with problems, which occur in other areas and asked the Snowmobile Club and Police Department to continue monitoring these issues. PARK NAMING COMMITTEE Commission member Carroll suggested that this item be deferred until the December meeting, in order that he may obtain some historical data regarding individual sites to be considered for official naming. FIRST DRAFT DEMOGRAPHIC STUDY Julie Lencowski, Student Intern from The University of Minnesota, indicated that her project for the department was to update the demographic information as contained in the Parks Systems Planned Study. Julie went on to indicate that she had completed her review of all housing data through August of 1985, which computed into a population of approximately 31,000 people. Continued review of the building permits from September of 1985 through 1986, indicated that the population is 40,000, excluding vacancy rates, which represents about 10 Julie indicated that the continuation of the study would break down the population within park service areas, for review at the December meeting. Commission member Alt questioned "What is the child to the adult ratio Julie indicated that the study was utilizing demographic figures provided by School District #196. She decided that there were approximately 3.34 individuals per single family household. Porter indicated that District #196 keeps records of all children from birth dates. It was suggested that the TRAILS 5 Adv. Parks Rec. Comm. November 7, 1986 demographer be contacted from the school district. Julie responded that, the City and the School District use different formats, as did the 1985 census, consequently it was very difficult to have the various boundaries match in order to ensure figures are accurate. She further went on to indicate that the City staff had contacted the school district to receive some assistance. After further questioning and discussion, Julie indicated that she hoped to have the complete report and the updated parks system pages at the December Commission meeting. PATRICK EAGAN PARK /LILLIAN MCCARTHY PARCEL Director of Parks and Recreation explaimed the past acquisition of Patrick Eagan Park, from Joe and Lillian McCarthy. He asked if the City wished to purchase, what is now the homesite of Lillian McCarthy, adjacent to Lexington Avenue and represents 3.8 acres. He indicated that the parcel was not presently being offered for sale. However, a family member did wish to see if the City still had an interest in the property. Carolyn Thurston inquired as to what the cost of the parcel was. The director responded that, an appraisal of the property was done in 1985, which concluded that the house and parcel was worth approximately $96,000. Chairman Martin responded that he has always been disappointed with the frontage along Lexington Avenue for Patrick Eagan Park, noting that the small road access virtually hides the park from users. Several Commission members spoke in support of necessity of acquiring this parcel for various reasons, including frontage, road access to the park, etc. On a motion by Kubik, seconded by Thurston, Staff was to continue to review purchasing of the property, as well as utilization of the house, should the property be placed on the market, or be offered to the City. Motion carried. Director of Parks and Recreation and the Staff has been working to update the Trails Map, for several months. He stated that he had just received the latest update from Tim Erkkila, who wished to give a first review with the Advisory Commission. He stressed the large amount of trails construction since the last update in the Comprehensive Trails Plan. He indicated that changes were made, with the trail along the right -of -way on Northview Park Road, south to Diffley. The second change was extended to the trail along Thomas Lake Road Extension, to the south of Deerwood; with the need to add Coachman Road Trail, as directed by the Commission previously. Dick Carroll commented that there was need to add the trail beneath the northern state's power easement (north /south) as a none-right-of-way trail. Commission members commented on other trail sections. The Director responded that at the December meeting, there will be a reduction for Commission members for final review and approval. Commission member Carroll sited the C -1 Classification for the south side of the east /west trail along Cliff Road, noting the high traffic use on this County Road. He suggested that the City continue to indicate this as future off -road trailway. DEVELOPMENT PROPOSAL Chairman Martin noted that Jim Sturm was now available, and the Commission could review the development reports. Jim Sturm first presented a brief overview of the proposal by Molenaro and Associates entitled "Pond View Mr. Sturm then explained Stafford Place, a proposed single family home development of approximately 200 lots, of which 114 did not meet current City Code. He also indicated that the City Engineering Department felt a north /south collector's street was necessary, and may well be placed through this development. He further indicated that he expects some changes in the plat, as a result of the non conformance of the zoning ordinance and the collector street issue. Also, he noted that there should be trails along the north /south road, trail access to the school site and along Diffley Road. Chairman Martin asked if Staff had contacted the school district to see if the trail is wanted. There was much discussion by the Advisory Commission concerning this plat. The Commission was in agreement that a trailway on Cliff Road, and along the north /south street as shown, should be required. A cash dedication would also be a requirement. After further discussion, and noting that the plat may be changed, the Commission determined that it would withhold it's final recommendation concerning the plat, until these revisions had been completed. Carolyn Thurston, noting that the issues of trails were such a concern with the Hampton Heights development; and this is the same developer; the Commission should go on record that no lot should be sold until the exact trail locations are determined. Upon a motion by Thurston, seconded by Carroll, with all Commission members in favor, it was moved that the Commission go on record that the pre selling of lots should not occur until all trail locations are determined, with a development agreement prepared. MANOR LASE ADDITION Planner Jim Sturm reviewed the proposed plat entitled "Manor Lake" indicating that Outlot C, was designated as commercial use. He stated that the Planning Commission continue this item, because the plat had failed to recognize uses to the south, and the contingency plan for 0utlot C should rezoning to commercial not be granted. Parks Planner, Stephen Sullivan, reviewed an analysis over the area proposed for parkland dedication. He indicated that the topography was relatively flat and represented the best area within the forty -three (43) acre parcel. The area was basically pasture, without any significant vegetation, with good visual orientation to the pond to the west. He stated that the parcel was relatively small and much tighter than the typical parks being done, and much closer in proximity to proposed homes. After further review by the Landscape Architect, the Commission questioned the size of the park parcel, in relation to the plat. Members noted that the size of the dedication appears to be less than that which would be required from the 10% dedication policy. Members were also concerned relative to the small size of lake access. Most Adv. Parks Rec. Comm. November 6, 1986 PARKS DEVELOPMENT DESIGN REVIEW /COST ESTIMATES SUN SHELTER WARMING HOUSE 7 Adv. Parks Rec. Comm. November 7, 1986 Commission members agreed that the general location shown was appropriate for the park. Members questioned access to the park via the proposed cul -de -sac, and the limited road frontage for access to the park from this development. There continued considerable discussion regarding the size of the park and the park access, as well trails connection to the west. Director Vraa responded that Staff had prepared a scheme which removed the cul -de -sac and would provide a curvilinear roadway. Commission members were in agreement with this layout, indicating the preference spot of road access, and visual connection to the park. After additional discussion, a motion by Carroll, seconded by Porter, with all members voting in favor, the Commission went on record as indicating that they favored the layout on sheet #4, with the additional road frontage, increase in parkland closer to the representation of the plat, and future expansion possibilities. Further, that the City receive dedication for platted outlots at this time, that a trail access to the west, within the proposed roadway shown in Outlot A, be provided, that south property acquisition provide for an open play space, and that the City recognize the unusual situation, in which the City does not typically have a neighborhood park under ten (10) acres and the necessity of providing for a smaller, atypical neighborhood park, as a result of roads isolating this neighborhood. Landscape Architect /Parks Planner, Steve Sullivan updated the Advisory Commission on the status of parks development, indicating that most of the work that is outstanding could be completed within two weeks, given favorable weather conditions. He stated that the building contractor is proceeding' well, but still very much behind schedule. Director of Parks and Recreation reviewed the cost estimate for the warming houses and the sun shelter at $32,340. and $10,250. respectively. He stated that in the case of the sun shelters, and if City forces were used a savings of $5,100 could be made. A savings of approximately $8,000 might be made from the warming house construction. He stated that the issue for the Commission was, if they desired to move ahead more quickly, the buildings should be constructed as part of a contract. If, however, the Commission felt that a slower approach could be used, City forces could build the shelters. In response to one question, the Director, responded that bid specifications for these buildings be done by staff, because of the similarity of construction techniques with current construction program and the simplicity of design. Chairman Martin was concerned about the number of windows shown. Member Caponi questioned how these facilities would be situated on the site and their orientation. Director Vraa responded, that the number and location of windows can be expanded quite easily. The design shown was a generic approach. Further, that the exact building location and orientation would be dependent upon the park. It would also have an impact on the location of doors and windows. After further discussion, and response to a question, the Director responded that he would recommend that the City forces build the sun shelters, in hopes of constructing between one and three in 1987. Further, that the warming house shelter be part of a building contract, that might go with Blue Cross /Blue Shield and Quarry Park. The first priority would be for Carnelian Park, which is slated for refurbishment in 1987. After additional discussion and a motion by Kubik, seconded by Masin, with all members voting in favor, the Staff recommendation included the warming house building contract, with City forces to complete the sun shelters be approved. LAND ACQUISITION Director of Parks and Recreation told the Advisory Commission that all acquisitions have now been completed for the Curry /Ohmann and Church parcel. Director indicated that the Derrick Land Company had not as yet closed on the parcels creating the Fairway Hills Addition, because of an apparent lack of funding. Commission member Thurston questioned, if this might not open the door for additional acquisition as the next athletic site. Commission discussed this possibility, and a motion by Thurston, seconded by Bertz, Staff was directed to review the possibility for additional acreage acquisition, within the Ohmann Estate for the next athletic site. Commission member Kubik moved, seconded by Carroll, that the Commission send a letter to Mr. Jim Curry thanking him for his cooperation with the City in securing his land for an addition to Northview Park. All members were in favor. BOND FUND SUMMARY Director of Parks and Recreation then reviewed a bond fund summary, prepared by the development, indicating that it was a status report on the expenditures to date. He reviewed the various figures, indicating that they were very preliminary, due to the work in process and still unknown certainties associated with parks yet to be developed. He stated that the bottom line was that the bond fund was very much on target. In response to a question from member Alt, the Director explained the transfer of $100,000 for the buildings from the parksite fund. He stated that this was at the direction of the Advisory Commission at the time the Commission was reviewing costs for these facilities. OTHER BUSINESS AND REPORTS LAWCON/LCMR Grant 8 Adv. Parks Rec. Comm. November 7, 1986 Director Vraa stated that he had received communications from State Senators Durenburger and Boschwitz concerning the City LAWCON application, as well as local Representatives. He felt that the funding for LAWCON /LCMR funds would be appropriated and that the grant for Thomas Lake Park would be approved. Building Interiors 9 Adv. Parks Rec. Comm. November 7, 1986 Maintenance Report Chairman Martin said that he appreciated the Maintenance Report, noting the amount of work that the maintenance staff had accomplished. Caponi Parcel -Site Visit Members discussed the pending visit to Caponi parcel for reviewal of the Community Art Center. Martin indicated that he would also like to review the parcel being proposed for development by Mr. Hall and Sienna Corporation. After discussion, the Commission agreed to view the sites beginning on Saturday, at 9:00 A.M. commencing at City Hall. Northview Park Road Director of Parks and Recreation stated, that the Northview Park Road, as a result of the Lexington Park Square development would be upgraded in order for construction to begin next year. Construction will be in phases to accommodate access to the park, and there will be storm water improvement plans. Members expressed interest in these storm water plans and a desire to review such plans prior to public hearings. Winter Rinks Priority Staff had prepared a maintenance and priority program for winter rinks. Director reviewed these plans as consistent with previous Commission direction. It was noted that this year's program should improve, as a result of the Street Department requiring less parks maintenance men to help plow streets in snow emergencies. Director responded that Staff has been researching the various carpeting and furniture available for installation at Trapp Farm Park and Goat Hill. However, he stated that none of this was approved in the parks bond fund and it would be appropriate for the Commission to now approve the staff purchasing of these items. A motion by Kubik, seconded by Caponi, with all members in favor, Staff was authorized to proceed with the purchase of carpeting and furniture for the two buildings, as discussed. Adv. Parks Rec. Comm. November 6, 1986' Softball Fees" Director of Parks and Recreation stated that the League Leadership Committee for the Softball Organization's have recommended that a $25.00 "new team initiation" fee be applied. The new team fee would then be deposited for use at Northview Park or other athletic facilities.. A motion by Bertz, seconded by Caponi, with all in favor, Staff was authorized to charge an initiation fee of $25.00 fee for new teams in the adult softball leagues. Rahn Roof Director Vraa updated the Advisory Commission on the Rahn roof status, indicating that a cost of $30,000 for the construction of a false roof was received. Staff is now proceeding with repair work under a proposal form, rather than the more expensive roof design. Waldron Parcel Director Vraa stated that he has received a copy of the certificate of title for the Kathy Waldron parcel, indicating it's size. Commission has already recommended acquistion of the parcel, but an offer price has not been determined. Staff recommended a price of $45,000 plus assessments. All members in favor. December Meeting Commission member Alt suggested that the December meeting be held at Trapp Farm Park. She suggested that this could be the Christmas party for the Commission. ADJOURNMENT There being no further business, the meeting of November 6th, 1986 was adjourned at 10:45 P.M.

Section 99 Subdivision 1. Same as 7.99 CHAPTER 7 The last sentence seems repetitious, or at least not readily understandable. CHAPTER 8 When reviewing Chapter 7 8 of the City Code as it relates to the function of the Parks and Recreation Department, the following concerns came to my attention: Chapter 7.08, Page 179 Regulation of Grass, Weeds, and Trees: Some provision should be provided to exempt park property designated by the Director of Parks and Recreation as undeveloped National Parkland from conforming to this ordinance. 5 Chapter 8.06 D 5, Page 195 The last sentence of this part of the ordinance about crossing a street at an angle of ninety (90) degrees is vague and ambiguous about the place to cross. Section 5 Parking Regulations CHAPTER 9 This chapter contains general parking information with little concerning parks. About the closest thing to us, is the fact that the City retains the right to say where it is legal or not to park. CHAPTER 10 This chapter is on public protection. It contains much concerning parks, and trees. Section 10.20 Section 10.21 Deals with the duties of the City Forester, diseased trees, and control of the diseases. Section 10.22 This regulates the planting and protection of trees in new subdivisions. This provides for: o Preserving all adequate sized trees if possible. o Replacement of any adquate tree that is removed during construction. o Replanting to be done along with approved landscape plan (not less than 1 1/2). o Trees preserved in right -of -ways. o No dead trees, stumps left after development. o Performance bond, or cash escrow paid by developer. o Required information a planting plan of same scale as preliminary plat submitted at time of preliminary plat includes: 1. The specific name, size and location of every proposed, and every existing, preservable tree. 2. The distance in feet between trees in any one row. 3. The nature of existing soil in the planting scale to a depth of 3 feet. 6 Conditions for Tree Planting: This part informs the developer how and what to plant. Section 10.23 This section gives general rules and regulations for park use (i.e., don't litter, etc.) Section 10.24 Water Regulations This covers boats, docks, rafts, and motors The rest of the chapter is on various regulations, such as curfew, drug paraphernalia, fire alarms and general do's and don'ts.

(PLANNED DEVELOPMENT) DATE OF PUBLIC HEARING: NOVEMBER 25, 1986 DATE OF REPORT: NOVEMBER 17, 1986 REPORTED BY: PLANNING ENGINEERING APPLICATION: An applibation has been submitted by Northwest Airlines requesting a Preliminary Plat for the Lone Oak 2nd Addition. This plat, on Outlot M of the 1st Addition, consists of 1 lot and A 2 outlots, totaling 82.3 acres. Lot 1 will be the 103,668 Sq. ft. Northwest Aerospace Training Facility. The Lone Oak P.D. was approved in March 1984. Outlot M was designated for Northwest Airlines' future development, therefore, the use is consistent with the P.D. exhibit. COMMENTS: The site plan for this project was reviewed in detail prior to the issuance of a .grading permit in October 1986. All Code requirements had been satisfied. At that time, the entire, 82.3 acre. parcel was to be platted into a single lot. Since then, the applicant has chosen to plat only the area needed for the Aerospace building and leave the remaining area as outlots. Outlot A, 15.15 acres, .will •basically provide access from the west. Outlot B, 26.74 acres, abuts O'Neill Drive to the north and. will be capable of accommodating another significant building. The Aerospace Facility and parking setbacks still meet Code require- ments as the site plan itself has not been changed. 341 parking stalls will be provided in 2. separate lots. 553 parking spaces would .be necessary in strict office designated areas.. Since this Aerospace building is a' 24 hour facility and for a specific user group, the parking appears sufficient. Parking and building expansion areas have been provided, both meeting Code requirements. GRADING /DRAINAGE: The required site grading for Lot 1, Block 1, of the Lone Oak 2nd Addition is proposed to be constructed in two phases. The first phase has already begun under the authority of Grading Permit #EX 01 -216, issued by Council action on October 7, 1986. Because the second phase involves encroachment into Eagan Pond FP -4 (DNR Wetland #250W), a DNR permit will be required before this second phase can be initiated. Generally, all drainage generated from this facility will be directed into this large wetland, with the exception of the extreme southeast corner, which will be directed into a newly created LONE OAK 2ND ADDITION NOVEMBER 25, 1986 PAGE TWO 1 ponding area. Pond FP -4 is presently receiving runoff from Ponds FP -5 and 11, with no downstream outlet currently available. Figure 1 shows the relationship of this property to the existing and proposed future storm water system requirements. The outlet for Pond FP -4 will be southwesterly to Pond FP -7, which has a positive outlet down to the Minnesota River. Extensive erosion control measures will have to be established to minimize the impact into these City and DNR protected wetlands as well as adjacent private property. The grading plan previously submitted and approved shows no slope steeper than 3:1 and no encroachment on private property. However, the proposed grading plan does encroach into the required storm water storage capacity as identified on the City's Comprehensive Master Plan. Either this Master Plan or the proposed grading plan will have to be revised to provide the required storage volume for storm water runoff in this portion of District "F UTILITIES: Neither sanitary sewer nor water main facilities are immediately available to allow the development of this facility. An internal lateral sanitary sewer presently exists within the boundaries of Lot 1, Block 1, of this proposed development. However, this sanitary sewer does not connect to downstream facilities and was constructed prematurely as a part of the 1st Addition grading and development schedule.' Therefore, it will be necessary to extend this existing sanitary sewer lateral southwesterly to the future Lone Oak Drive thence westerly to the existing trunk facility adjacent to T.H. 55/149 intersection. In addition, an 8" sanitary lateral will have to be constructed to the northwest corner of Lot 1, Block 1, to provide future service for unplatted parcel 010 -29, located south of O'Neill Drive and north of the existing Northwest Airlines Corporate Headquarters. Figure 2 shows the relationship of the existing and required trunk sanitary sewer facilities. The completion of the trunk water main system, in accordance with the City's Master Plan for this area, eventually requires the looped connection from Lone Oak Road up to O'Neill Drive through this proposed development. Figure 3 shows the relationship and proposed trunk water main necessary to service the ultimate development in this section of the City. As a result of a detailed analysis evaluating elevations and required fire flows, the northerly portion of the 12" water main will have to be installed along O'Neill Drive to this development with an 8" connection to the existing loop around the N.W. Airline Corporate Headquarters to the west. The completion of this 12" trunk water main loop to Lone Oak Road will not be necessary until that property develops. The alignment of this southwesterly extension to Lone Oak Road is dependent upon a conceptual layout of the future development south of this proposed Lone Oakr2nd Addition. LONE OAK 2ND ADDITION NOVEMBER 25, 1986 PAGE THREE In order to provide sanitary sewer, water and storm sewer facilities to allow the development of this proposal, it will require the developer's financial commitment or authorization by Council action for the installation of these trunk facilities through adjacent property. Internal lateral utilities, whether installed privately or under a City contract, must be in conformance with City approved engineering standards and specifications. STREETS /ACCESS /CIRCULATION: Access to Lot 1, Block 1, will be obtained through the construction of an internal private street constructed to City standards from O'Neill Drive along the northwesterly edge of the Lone Oak 2nd Addition. A secondary access to the Northwest Airlines Corporate Headquarter parking lot will be provided to the west. However, the final street configuration is dependent upon the approval of the Department of Natural Resources (DNR) due to the fill required within or adjacent to DNR Protected Wetland #250W. With O'Neill Drive being the only primary access to this facility, it will be necessary to complete the upgrading of this street. 4 Presently, the easterly access to Delaware Avenue in Mendota Heights and the westerly access to T.H. 149 have been completed as a part of the upgrading of I -494. The completion of the middle section of O'Neill Drive to City standards should be ordered by Council action prior to final plat approval. EASEMENTS /RIGHTS OF WAY /PERMITS: Due to the requirements of extending trunk sanitary sewer, water main, storm sewer facilities and improving O'Neill Drive to City standards impacting properties adjacent to and beyond this development to provide service to this proposed facility, it will be necessary to ensure that all permanent and temporary construction easements will be made available prior to construction initiation. Therefore, it will be necessary to have this development responsible for the acquisition of all required easements or a financial escrow to cover all anticipated costs associated with acquisition through adverse condemnation. It will be necessary to acquire all Department of Natural Resources (DNR) permits prior to final plat approval. The acquisition of the required Minnesota Pollution Control Agency (MPCA), Metropolitan Waste Water Control Commission (MWCC) and Department of Health sewer and water extension permits will be required prior to the issuance of a utility construction permit. An MPCA Indirect Source Permit will also be required prior to final plat approval. Ponding easements of sufficient configuration shall be dedicated as required by City staff to incorporate the necessary storm water storage volumes for Ponds FP -4, 41 and 11 and shall be shown on the final plat. All internal public utilities shall have permanent utility easements dedicated of sufficient width depending upon the final alignment and depth. LONE OAK 2ND ADDITION NOVEMBER 25, 1986 PAGE FOUR ASSESSMENTS: Trunk area sanitary sewer has been previously assessed over all portions proposed to be included in the Lone Oak 2nd Addition. No further assessments are associated with trunk area sanitary sewer. Trunk area storm sewer was assessed over that portion lying within the west half of Section 1 (Outlot A). Lot 1, Block 1, and Outlot B have not yet been assessed for trunk area storm sewer improvements. With the required trunk area storm sewer facilities necessary to service this deveelopment, it will be required to have this development agree to those trunk area assessments through the Development Contract. In addition, trunk area water assessments have not yet been levied due to the lack of trunk water main facilities in this general area. As a condition of final plat approval, it will be necessary to have this development agree to these related trunk area water assessments. A portion of O'Neill Drive has already been upgraded to City standards near the northeast corner of this proposed subdivision. All assessments associated with this improvement performed by MnDOT and the future improvement of O'Neill Drive required with this final plat shall be the responsibility of the developer for its respresentative frontage. All trunk area assessment obligations shall be in accordance with the rates in effect at the time of final plat approval and provide credit for the required dedicated ponding easements. These assessment obligations are estimated with 1986 rates as follows: Item Trunk Area Storm Sewer Trunk Area Water O'Neill Dr. Quantity Rate Amount 43.0 Ac. 0.075 /sf $140,481.00 58.14 Ac. 3,020 /ac $175,583.00 1070 LF 78.45/1f 83,950.00 Project Code 302 Final quantities will be calculated based on final plat dimensions. LONE OAK 2ND ADDITION PAGE FIVE CONDITIONS: LONE OAK 2ND ADDITION 1.

FIG. #1 standard plate SUBJECT: APPLICANT: LOCATION: EXISTING ZONING: DATE OF PUBLIC HEARING: DATE OF REPORT: REPORTED BY: CITY OF EAGAN Rezoning Preliminary Plat (Pinecrest Addition) Huttner Construction SW 4, Section 15' A (Ag.) November 25, 1986 November 17, 1986 Planning and Engineering APPLICATION: Two separate applications have been submitted by Huttner Construction requesting a rezoning of 7 agricultural acres to an R -1 (single family) district and a Preliminary Plat for the Pinecrest Addition. This plat consists of 17 lots end is located south of Crestridge Lane, abutting Fish Lake Park on the south property line. The Comprehensive Guide Plan des- ignates this area as _R -1, therefore an Amendment will not be necessary. LANDUSE /SITE PLAN: This 350' wide parcel is surrounded by ag. parcels to the east and west. This City's Park Department owns property south of this parcel, some or all of which may be under water. The master plan for this park calls for a trail connection from the recently completed 'built' portion of the park to the peninsula on the north side of the lake. Either an easement or land dedication will be necessary for this connection. Fish Lake has a General •Development designation under the City's Shoreland Ordinance. This will require that the homes on lots 7, 8 and 9 be a minimum of 50' from the Ordinary High' Water Eleva- tion (OHWE). The submitted grading plan places the building pads at least 85' in lineal distance and approximately 25' above that elevation. All lots conform to Code requirements. in terms of size, frontage and square footage. The original submission was for 17 lots served by a single 650' cul -de -sac. Other options .have been discussed including one with a stub street to the West and one with a connection to Kolstad Lane. The gross density for the 16 lot proposal would be 2.3 units /acre and 2.4 units /acre for the 17 lot proposal. The site has pockets of dense vegetation including mature hardwood species and a large area of scotch pines near the center of the site. The topography contains knolls and depressions and falls dramatically towards the lake. The proposed cul -de -sac will be nearly 30' above the normal lake elevation. The applicant will be _the site builder for this subdivision and the homes will be.in the $140,000 range. PINECREST ADDITION NOVEMBER 25, 1986 PAGE TWO GRADING /DRAINAGE: Presently, approximately the northern one -third of this parcel drains north towards Crestridge Lane with the southern two thirds draining south into Fish Lake. This proposed development will be performing extensive grading on this site resulting in cuts of approximately 10 12' through the middle portion of this parcel, resulting in the majority of the drainage being directed by an internal storm sewer system into Fish Lake. Fish Lake is presently controlled at an elevation of 844.8 by means of an existing storm sewer system down to the Minnesota River. Due to the sensitivity and qaulity of this lake, extensive erosion control measures will have to be implemented during the development phases. UTILITIES: A 15" trunk sanitary sewer line of sufficient depth and capacity is immediately available across the southern portion of this unplatted parcel. The internal sewer lateral system will connect directly into this trunk facility. A water main of sufficient capacity and pressure is immediately available within Crestridge Lane. This proposed development will obtain service by extending an internal 6" water lateral and provide a stub for future extension to the west for future looping if, and when, the adjacent unplatted parcels develop in a similar manner. STREET CONFIGURATION /CIRCULATION: The initial application for the development of this parcel provided for only a singular cul -de -sac taking access from Crestridge Lane approximately 650' in length, exceeding the 500' maximium required by code. As a part of the overall development of these several remaining unplatted parcels between Crestridge Lane and Fish Lake, it has been determined that a stub street should be constructed from this proposed cul -de -sac to the west boundaries of this plat for future extensions. The center line of this stub street should be approximately 400' south of the center line at Crestridge Lane. Figure 1 shows the recommended master plan for the future development of these unplatted parcels. Figure 2 shows an alternate configuration that was reviewed by staff. However, it would require the replatting of the existing Buffer Hills cul -de -sac (adjacent to Pilot Knob Road) and would require the dedication and construction of a public street and right -of -way through the adjacent easterly parcel to Kolstad Road. Subsequently, the developer has revised his proposed preliminary plat to conform to the recommendations consistent with Figure 1. A condition should be placed to ensure that no direct driveway access is taken from a stub street to the west to minimize winter snow and ice control maintenance requirements. EASEMENTS /RIGHTS -OF -WAY: Presently, there is a 40 -42' half right of -way for Crestridge Lane as dedicated with the previous Pilot Knob Heights 1st Addition. Crestridge Lane is presently constructed to its ultimate design standards, which requires only a maximum 30' half right -of -way. Therefore, it is staff's recommendation that as a condition of this plat all excess right -of -way beyond a 30' half right -of -lay be vacated and included as developable property with this plat. PINECREST ADDITION NOVEMBER 25, 1986 PAGE THREE Staff concurs with the proposed 60' public right -of -way dedication for the internal street servicing this proposed development. All other internal drainage and utility easements shall be dedicated as required by the final alignment and depth of any internal utility systems constructed outside of dedicated right -of -way. ASSESSMENTS: Both Outlot A of Pilot Knob Heights 1st Addition and the unplatted parcel 070 -51 have been previously assessed for trunk area sanitary sewer and water benefits. Therefore, there are no additional assessment obligations associated with these trunk area utilities. However, the trunk area storm sewer assessment levied under Project #77 in 1972 did not cover the entire area of both parcels. Subsequently, there are five acres proposed to be platted under this application that have not fulfilled their trunk area storm sewer obligation. In addition, when the trunk area sanitary sewer was installed across the southern boundary of this parcel, the lateral benefit was deferred until time of development and /or connection. Subsequently, this development will be responsible for 350' of lateral benefit from trunk sanitary sewer. A detailed research of the assessment records also revealed that there are $1, 542.86 of outstanding levied special assessments that have never been collected due to Outlot A going tax forfeit. This outstanding amount, plus any interest due, should be the responsibility of this development. While the outstanding additional assessment obligations associated with this plat will be calculated at the rates in effect at the time of final plat approval, the financial obligation has been estimated for informational purposes only using the 1986 rates as follows: Proj. Item Quantity Rate Amount Code Trunk Area Storm Sewer 218,642.6/sf 0.05 /sf $10,932.13 279 Lateral Benefit from Trunk Sanitary Sewer 350/1f $28.69/lf 10,041.50 58 Outstanding Balance from 1,542.86 Tax Forfeit (Outlot A) PINECREST ADDITION NOVEMBER 25, 1986 PAGE FOUR CONDITIONS: PINECREST PRELIMINARY PLAT 1. The property owner and developer shall petition for the vacation of excess public right -of -way for Crestridge Lane beyond a 30' half right -of -way and this vacated right -of -way shall be incorporated into the proposed plat. 2. This development shall dedicate all necessary ponding easements for Fish Lake necessary to incorporate the 847.0 elevation. 3. This development shall dedicate all utility easements outside of public right -of -way as required by the alignment and depth of all proposed public utilities. 4. This development shall submit and adhere to a detailed erosion control plan in accordance with City standards and special requirements for this development. 5 No driveway accesses shall be taken from the stub street to the west. 6. This development shall be responsible for all outstanding assessment obligations at the rates in effect at the time of final plat approval. 7. All public street and utility improvements shall be designed and installed in accordance with City engineering standards. 8. All standard platting conditions shall be adhered to. 9.

The first application is a request to rezone 88.76 acres of A (Agricultural Land) and 2.2 acres of RB (Roadside Business) to a Regional Shopping Center Planned Development RSC (P.D.). The second application is for a Preliminary Plat of Lots 1, 2, 3 and 5 in the first phase of this major shopping complex. The Comprehensive Guide Plan designates this area as R -II (Mixed Residential, 3 -6 dwelling units per acre) and P (Parks Public Space). Therefore, an Amendment will be necessary. This proposal is located north of Diffley Road at the 35 -E interchange and has its easterly property line approximately 250' east of Thomas Lake Road. PROJECT SCOPE: The proposal calls for a phased development consisting primarily of five major anchors located within two large building structures. These include a 102,000 sq. ft. Target store, a 170,000 sq. ft. Northwest Swim and Racquet Club and a 60,000 sq. ft. department store in the first phase. Two other larger tenants may include a childrens store, sporting goods store or a catalog showroom -type store. Supporting retail uses would fill in the areas between these major tenants, creating a Phase I total of 470,000 sq. ft. of gross building area. Phase II would contain an 89,000 sq. ft. home improvement center and a 75,000 sq. ft. discount grocery store. Supporting uses will also be included. Both phases will be physically separated by a proposed extention of Johnny Cake Ridge Road. This road will loop to the east and tie into the extention of Thomas Lake Road from Diffley Road to Deerwood Drive. 35E DIFFLEY CENTER NOVEMBER 25, 1986 PAGE TWO A 6 -acre area east of the Thomas Lake Road extention has been designated for 40,000 sq. ft. of office use and would act as a buffer to the adjacent undeveloped land to the east. An 8.4 acre area on the northeast portion of the site has been designated as a Public Use area. This may be used to fulfill the City's Park Dedication requirement. ZONING LAND USE: Currently, this site is inactive. The area closest to the 35 -E interchange was used as a temporary cement plant for the 35 -E construction through Eagan. At that time, a grading permit was issued, and approximately 1/3 of the site has been rough graded. The natural characteristic of the site is one of knolls with a mixture of young to mature hardwood trees, most of which are oaks. This 90 +acre site is surrounded by agricultural parcels to the north and east. A possible City water storage facility near the northwest portion of the site and along 35 -E has been discussed, but is not an imminent proposal. The Deerfield Apartment project consisting of 324 units is across Diffley to the south, along with RB (Roadside Business) zoning extending west to the freeway. Across 35 -E to the west is more high density housing and the Blackhawk Plaza Shopping Center. The 100' wide Williams Brothers Pipeline easement crosses the site in a northerly manner near the eastern portion of the site. The pipeline will be lowered in this area when the Diffley Road improvements take place.. SITE PLAN /CODE CONFORMANCE: Johnny Cake and Thomas Lake Roads will provide the actual access into this site and to the major parking areas required for retail use. Instead of breaking down the parking requirements for each proposed user, staff based the parking requirements on the worst possible scenerio, or that of all retail use. In that case, Code would require 2,966 parking stalls. This site plan provides 3,442 stalls. In other cities, health clubs are often reviewed separately because of the specific nature of the facility. Also, their hours of operation do not necessarily correspond with those of the adjacent retail use. In any event, cross easements will be a necessity for the overall continuity of this project. Each building component should be reviewed in detail by the staff /Advisory Commissions and Council prior to final plat submission in order that specific concerns can be addressed and resolved. The Planned Development Agreement should be signed before any site development and /or grading takes place. The overall lot coverage is 18.5% and 30% is permitted by City Code in RSC Districts. All setbacks meet Code requirements in this Preliminary Plat proposal. 35E DIFFLEY CENTER NOVEMBER 25, 1986 PAGE THREE TRAFFIC: The actual amount of traffic and the patterns generated by this proposal have inititated much of the prepublic hearing discussion. This site will be serviced by two City collector streets, a County road and a full diamond Interstate highway interchange. All of these roads have been or will be designed to accommodate the additional traffic in the area. Staff has reviewed preliminary numbers that indicate the traffic generated by this development should not cause undue stress on the improved roadway system. However, the detailed traffic study has not been reviewed in detail at this point in time. Pilot Knob Road will begin to be improved in 1987 and take two years to complete. Cliff Road is also scheduled for improvements in the near future. Since Diffley and Cliff Roads cannot both be closed at the same time, there will have to be a coordinated effort between the County, City and developer regarding the improvement schedule in order to minimize traffic delays within the City. A detailed traffic analysis has been provided by B.R.W., Inc. It has been prepared to include a "Post Development" scenerio, that is, with this project completed, Blackhawk Plaza fully developed and all existing traffic around the site included in the ADTS (Average Daily Trips) figures. All roads were calculated on their improved status or proposed design capabilities. ENVIRONMENTALS: An EAW (Environmental Assessment Worksheet) and ISP (Indirect Source Permit) will be required and staff is currently working with the appropriate governmental agencies to determine what elements will be required to obtain the specific permit. It has not been determined whether a full EIS (Environmental Impact Statement) will be necessary. Other permits may need to be obtained from the MWCC (Metropolitan Waste Control Commission) and the Metropolitan Council. Another concern the City must deal with is the amount of existing retail commercial zoning in Eagan as well as the amount in other surrounding cities. Also related would be the market absorption for a major complex of this type. Both the Target and Northwest Swim and Racquet Club have committed to this specific site and to the first phase of development. FIRE POLICE PROTECTION: Both of these departments have only reviewed this proposal on a preliminary basis. However, there were no major issues that would appear to be unresolvable with the proper platting and building permit procedure. Access to and within the site will be critical to the safety of all those in the general area. Aside from the Johnny Cake Ridge Road and Thomas Lake Road improvements, all other interior parking areas and road systems shall be reviewed more extensively with the detailed building and individual lot plans. 35E DIFFLEY CENTER NOVEMBER 25, 1986 PAGE FOUR PARK ISSUES: Trails along Diffley and Thomas Lake Roads will be required and the APRC (Advisory Parxs Recreation Commission) will need to review this project for the appropriateness of the Parks Dedication fee. The Public Recreation portion of this site has been deliberately left undeveloped so that the City would be able to study this area in greater detail. Should that area not fit in with the City's overall Park System and Master Plan, another use will need to be proposed prior to the signing of the P.D. Agreement. SITE AESTHETICS: Staff is recommending that an overall landscape plan be submitted to ensure compatability of species and overall continuity in this large proposal. All plant material sizes shall be in conformance with the City's Landscape Policy. Special design emphasis will be placed on the berming and screening of parking areas, trash locations and loading /service areas. All detailed plans submitted on a grading plan would then be required with the individual lot plans. These plans should be prepared by a Landscape Architect familiar with native species and plant material hardiness. An overall Sign Agreement shall also be entered into by the developer prior to the issuance of any individual sign permits. This will eliminate any undue variances and provide a more uniform cohesive development. GRADING /DRAINAGE: The western portion of this site has been previously graded under Excavation Permit No. EX 21 -194 in 1984 in conjunction with the construction of I -35E. The eastern two thirds of this site still remains in the natural undisturbed condition consisting of extreme elevation differentials of approximately 60'. The proposed grading of this development would include the development of seven onsite storm water detention basins. Several extensive retaining walls will have to be constructed along adjacent property lines due to the extreme change in elevations. The final approved grading plan adjacent to Diffley Road must be compatible with the final design grades of the future County Road 30 (Diffley Road) road improvements. The required grading of the overall site involves extensive cuts and fills up to 40'. Although this development is proposed to be constructed in a phased program, it is recommended that the grading of the entire site be completed with the first phase to ensure that all the storm water detention basins are developed and to minimize the negative impact of potential significant unbalanced final cut /fill quantities and to allow the construction of the required retaining wall structures, buffer landscape screening and permanent vegetation restoration for erosion control. 35E DIFFLEY CENTER NOVEMBER 25, 1986 PAGE FIVE The two storm water detention basins in the extreme southeast corner of this development will have to have a storm sewer outlet extended approximately 600' east along Diffley Road to the existing City trunk system, which has adequate capacity to handle this proposed runoff. The remaining five proposed storm water detention basins which provide for a total storage volume of 25 acre -feet shall be interconnected by a master storm sewer system approved by the City with an ultimate discharge to the north. The storm sewer system will have to be extended across the adjacent property (Francis Franz) to the existing City /state storm sewer system north of Deerwood Drive adjacent to I -35E. The final storm sewer and drainage system will have to be revised to eliminate the proposed discharge into the I -35E right -of -way along the western boundaries of this development due to current restrictions by MnDOT. In addition, a storm sewer system will have to be extended to the south of Diffley Road to provide a future outlet with a capacity of approximately 65 CFS. In summary, there are no major concerns associated with the grading and drainage of this proposed development subject to maintaining the proposed onsite storm water detention capacities and extending the storm sewer system to existing downstream trunk facilities. Figure 1 shows the relationship and the compatibility of this development to the existing comprehensive storm sewer system. These existing trunk facilities will provide positive drainage all the way to the Minnesota River. UTILITIES: Trunk sanitary sewer of sufficient depth and capacity is presently available on Diffley Road approximately 1,000' east of Thomas Lake Road. Figure 2 shows the relationship of this property to the existing trunk sanitary sewer system. This development will require the westerly extension of a minimum 10" diameter sanitary sewer along Diffley Road with an internal 8" lateral distribution system providing for a stub to the north (Francis Franz property) for possible extension. Water main of sufficient capacity and pressure is immediately available along Diffley Road from Johnny Cake Ridge Road to the east. Figure 3 shows the relationship of this development to the existing and proposed trunk water distribution system. The existing 16" trunk water main extending south from Diffley Road along the previous proposed alignment of Johnny Cake Ridge Road will have to be relocated to conform to the proposed new alignment of Johnny Cake Ridge Road and its intersection with Diffley Road. This 16" trunk water main must then continue through this development to the extreme northeast corner for a future extension and connection to Deerwood Drive. A 12" trunk water main extension from the Thomas Lake Road alignment must also connect with this 16" extension to provide an adequate looped trunk system. The future extension and connection to the Deerwood Drive trunk water main will not be necessary,due to the fact that the northern boundaries of this proposed development is the dividing line between the high and intermediate pressure zones of the City's overall trunk distribution 35E DIFFLEY CENTER NOVEMBER 25, 1986 PAGE SIX system. The remainder of the internal lateral distribution system will have to have its size and alignment designed with the final site plan configuration and building plan review to ensure adequate pressure and fire hydrant placement. STREETS /ACCESS /CIRCULATION: This site will be serviced primarily by County Road 30 (Diffley Road), which is a two -lane rural road section currently scheduled for upgrading by Dakota County in 1988- 89. It is proposed to be constructed as a four -lane divided roadway, with trailways on both sides, providing signalized intersections at Johnny Cake Ridge Road and Thomas Lake Road which will be the two major access points to this proposed development. Any additional accesses onto County Road 30 will be restricted to "right -in /right -out" at specific locations as may be approved by Dakota County. It is recommended that the Johnny Cake Ridge Road extension and the Thomas Lake Road extension, to their mutual intersection, be designed as four -lane divided roadways with a trailway on both sides. The Thomas Lake Road extension to the northeast corner of this development shall continue the trailway system on one side, with the final street width design yet to be determined by the City's thoroughfare plan analysis. In addition, a 32' street shall be stubbed to the north at the northern loop of Johnny Cake Ridge Road, between the two proposed storm water detention ,basins, to provide a secondary outlet for the future development of this adjacent parcel (Francis Franz). While the developer has submitted detailed traffic generation, distribution and impact analysis studies, the staff has not had adequate time to review this complex information to provide adequate comments. However, with the pending improvement of Diffley Road (County Road 30) and Pilot Knob Road (County Road 31), along with the existingl -35E interchange, it is not anticipated that this development will generate traffic problems that cannot be handled by these existing and scheduled future road improvements. However, additional detailed studies will be necessary to verify this along with the final size and alignment of the Thomas Lake Road extension to the north and its ultimate connection to Deerwood Drive. This development shall be responsible for its appropriate financial costs associated with the upgrading of County Road 30, the full cost of the Johnny Cake Ridge Road and Thomas Lake Road extensions and the related trailways, including the north side of Diffley Road. The proposed intersection of the Thomas Lake Road extension at Diffley Road shall line up with the existing Thomas Lake Road intersection to the south. EASEMENTS /RIGHTS -OF- WAY /PERMITS: The final configuration and location of the storm water detention basins incorporating the required storage volumes shall be defined and incorporated on the final plat. 35E DIFFLEY CENTER NOVEMBER 25, 1986 PAGE SEVEN Johnny Cake Ridge Road and Thomas Lake Road extensions shall provide for a minimum 100' right -of -way with Thomas Lake Road north of its intersection with Johnny Cake Ridge Road being a minimum 80' right of -way. Sufficient right -of -way and temporary construction easements shall be dedicated as required by the County for the upgrading of County Road 30. This development shall be responsible for the acquisition of all easements necessary to extend the sanitary sewer and storm sewer systems to the existing trunk facilities. This developer shall be responsible for ensuring that all regulatory agency permits (MPCA, MWCC, Department of Health, etc.) are acquired prior to final plat approval or building permit issuance, whichever is required by the affected agency. ASSESSMENTS: All property proposed to be developed under this application has been previously assessed for trunk area sanitary sewer under Project #88. Therefore, there are no further assessment obligations for trunk area sanitary sewer. Except for the small triangular residual of Hillandale Addition #1 in the southwestern corner of this development, no trunk area water assessment has previously been levied. Therefore, this development will be responsible for trunk area water assessments at the commercial /industrial rate over the net assessable area excluding public dedicated right -of -way and ponding easements. There is a pending assessment against the northerly most 220' of this proposed development from Project #372 (I -35E /Deerwood Drive). However, this pending assessment was calculated based on a single family residential useage. Therefore, this portion will be responsible for the additional assessments associated with the proposed upgrading to commercial /industrial. The remainder of the property to be developed has never been assessed for its trunk area storm sewer obligations. This will also have to be calculated at the commercial /industrial rates. Appropriate credits will be provided for all dedicated public right -of -way and ponding easements. The lateral benefit assessment from the existing 16" trunk water main along Diffley Road was deferred at the time of installation until development of the adjacent benefitting properties. Therefore, this development will be responsible for this lateral benefit calculated at half the frontage adjacent to this trunk water main. This development will also be responsible for assessments associated with the future upgrading of Diffley Road and the related trailway. 35E DIFFLEY CENTER NOVEMBER 25, 1986 PAGE EIGHT This development will be responsible for all costs associated with the extension of sanitary sewer, water, storm sewer laterals and internal streets necessary to service this development. The final assessment obligations will be calculated based on the final net assessable area and the rates in effect at the time of final plat approval. Based on 1986 rates and gross area, less a 20% credit for future right -of -way and easements, these assessment obligations are estimated as follows: Item Quantity Rate Amount Proj.

BASE FLOODING Base flooding of the hockey rinks and pleasure rinks will begin on Monday, December 8th. Tom Schuster and Rich Pelletier have agreed to work the night shift of 9:30 A.M. to 6:00 A.M., during this period. Both tankers will be utilized to accomplish flooding in the most effective manner. The balance of the maintenance staff will continue to work the regular shift of 7:00 A.M. to 3:30 P.M. during the base flooding program. Flooding will continue, of course, during the daylight hours. We anticipate that base flooding will be completed by Wednesday, December 17th weather permitting. RINK MAINTENANCE ROUTES Similar to last year, two flooding crews will be utilized. The flooding routes will be staffed by the following maintenance workers: Route 1 Route 2 Don Buecksler Rich Pelletier Steve Hadden Tom Schuster Scott Eppen Gary Skogstad Dan Curtin will serve as a swing man when other employees are ill, or on vacation, etc. Dan will assist Steve Taylor with equipment maintenance and perform other odd jobs around the shop. Dan will swing to Route #1, replacing Rich Pelletier, when carpentry activities are on -line. Daily flooding routes have been established to place priority on maintenance of our Class "A" rinks and then Class "B "C and pleasure rinks in descending order of priority. Some modifications of the prioritites have been made to address the logistics of travel from one site to another. Route 1 Route 2 Site 1. Well Site 2. Evergreen 3. Ridgecliff 4. Rahn 5. Carnelian 6. Woodhaven 7. Cedar Pond Class A C B A B B C Route 1 Route 2 1. Well Site 2. Evergreen 3. Ridgecliff 4. Rahn 5. Carnelian 6. Woodhaven 7. Cedar Pond 8. Goat Hill (assistance) 9. Trapp Farm (assistance) Site Class 1. Goat Hill A 2. Pilot Knob B 3. Highview C 4. Country Home C 5. Lexington C 6. Burr Oaks C 7. Woodhaven (assistance) B Route#1 will be responsible for maintaining 7 hockey rinks and 7 pleasure rinks; Route #2 will have 5 hockey rinks and 6 pleasure rinks. The added distance of travel on Route #2 should help to balance the time commitments of both routes. If Route #2 completes it's work sooner than Route #1, assistance will be provided at Woodhaven and /or Cedar Pond Parks as necessary. A map depicting each route and classifications is attached, for your convenience. A program of Saturday rink maintenance will be implemented. Emphasis will be placed on snow removal on Class A and Class B rinks. Two maintenance workers will be brought in on Saturday, working from 4:30 A.M. to 9:30 A.M. to accomplish these tasks. During periods of heavier snows additional call -outs will be required. SNOW PLOWING Access road and parking lot snow removal will be integrated into the rink maintenance routes. Daily (as needed) snow removal and sanding will occur at the following sites: 1. Goat Hill 2. Trapp Farm 3. Walnut Hill 4. Patrick Eagan 5. Fish Lake 6. Pilot Knob 7. Highview 8. Country Home 9. Burr Oaks Route #1 will provide assistance to Route #2 (with snow removal) as dictated by snow depth or other outside factors (no pun intended). Obviously, the greatest volume of snow plowing will occur on Route #2 with inclusion of the Trapp Farm and. Goat Hill parking lots. Also, do you wish to have Walnut Hill on the list? I felt the potential for winter use was there, e.g., archery, passive skiing, sledding, playground use, etc. All parking lot snow removal will be accomplished by parks staff. Only in the very deepest snows would the Streets Department be called on to assist with parks plowing. Obviously, streets and cul -de -sac plowing is the top priority in the Streets Department. For that reason, I did not call upon their department for incorporation of any park roads and lots into their routes, i.e, we would have ended up at the bottom of the list. The Streets Department will be maintaining at parking lots at all of the municipal buildings this winter. Good news! EQUIPMENT Allocation of departmental equipment, to each route, will be as follows: Route 1 Groundsmaster /Broom #332 Groundsmaster /Snowblower #333 Truck /Trailer #304 Plowing Truck #314 Tanker #315 Route 2 Groundsmaster /Broom #335 Groundsmaster /Snowblower #334 Truck /Trailer #307 Plowing Truck #310 Tanker #312 VACATION During winter school break the flooding route schedules will be adjusted to better accommodate area youth. From December 22nd through January 2nd the maintenance staff will work from 5:00 A.M. to 1:30 P.M. daily. This schedule change will affect the entire crew including Steve Taylor, whose primary responsibility this winter will be equipment maintenance. STREET DEPARTMENT NEEDS As you know, the Streets Department has made modifications to it's plows, and contracted out one snowplowing route, which will have positive implications for resource needs in our department. Steve Taylor is being assigned to cul- de -sac Route #4. Steve is the only person who will be needed from our department on a regular basis. Asssuming the weather is "average" we expect Steve to be on this assignment about 8 to 10 times during the winter. During heavy snows, sickness, and so on, it is possible that more staff from parks maintenance division will be called upon to assist with plowing in the Streets Department. In order to respond to these shortages we have prepared for the following scenarios: A. Two employees needed: o two brooms (2) o two blowers (2) o two plows /tankers (2) o supervisor floater (1) B. Three employees needed: o two brooms (2) o two blowers (2) o two plows /tankers (2) (incl. supervisor) C. Four employees needed: o two brooms (2) o two blowers (2) o one plow (tanker) (supervisor) o emphasis on A and B rinks D. Five employees needed: o one plow (1) o one broom (1) o one blower (1) o one tanker (1) (supervisor) o emphasis on A rinks CROSS COUNTRY /SLEDDING HILL MAINTENANCE I have firmed up our agreement with Steve Michaud on winter trail and sledding hill grooming. Lakeville will furnish us with the grooming machine and operator for one eight to ten hour day per week preferably Thursdays. The cost, as we discussed, will be $13.00 per hour for operator and machine. Assuming 80 to 100 hours for a 10 -12 week period, the total cost to our department will be in the range of $1,000 to $1,300. Grooming will occur at Patrick Eagan, Blackhawk, and Blue Cross /Blue Shield Trails and at Trapp Farm Park sledding hill. In the meantime close communication will be maintained with Lakeville Parks and Recreation. OTHER PROJECTS Available indoor time will be consumed in a variety of construction and maintenance activities. My objectives for the maintenace staff are to: 1. Begin construction on a number of park identification signs. (Will the Commission be reviewing 2. Complete construction on the new picnic tables (60). 3. Rehab all existing tables needing work. 4. Construct new players benches using frames salvaged from "old" benches. 5. Commit time to implementation and management of vehicle and equipment maintenance program. 6. Rehabilitation of Rahn Building. 7. Construction of hockey and soccer goals. JV /bls MEMO TO: ADVISORY PARKS RECREATION COMMISSION C/O KEN VRAA, DIRECTOR OF PARKS RECREATION FROM: THOMAS A COLBERT, DIRECTOR OF PUBLIC WORKS DATE: DECEMBER 2, 1986 SUBJECT: STORM SEWER IMPACT ON PARK PROPERTY It is my understanding that there has been growing concern regarding the impact of storm sewer improvements (or lack thereof) on park property as both proceed with development in accordance with their respective master plans. I will be happy to provide a detailed explanation of the City's Comprehensive Storm Sewer Plan and its impact on park property at the Advisory Parks Recreation Commission meeting to be held on December 4, 1986. In anticipation of that presentation, the following background information may be helpful in understanding the compatability and reliance of one upon the other. In the early 1960's, the City (Township) authorized a Comprehensive Storm Sewer Plan to be prepared and used as a guide to assist in the orderly development of the community. This Master Plan was revised in 1972, 1978 and, most recently, 1984. It was prepared by the consulting firm of Bonestroo, Rosene, Anderlik Associates, Inc., who evaluated the topography of the City and established several major and subdrainage districts. Each subdrainage district was created by analyzing the overland surface water flow into an existing water body or low lying drainage basin. The City's zoning and future Land Use Guide were then used to determine the amount of runoff generated into each drainage basin. Through the interconnection of these drainage basins by an integrated storm sewer system, all surface water runoff eventually reached the Minnesota River. Since the initial implementation of this Comprehensive Plan, the City has adopted three basic philosophies for creating and incorporating as many ponding areas as possible: 1. To reduce the size and resultant cost of the storm sewer system to the Minnesota River. 2. To create and maximize a ground water recharge system. 3. To contain and retain sediments and nutrients at each level before discharging water further downstream. The attached exhibits show the relationship of existing park land to the City's comprehensive storm sewer system and drainage basins. The majority of these park lands are presently serviced with a storm sewer system which either drains the park land or provides an outlet for the drainage basin located adjacent to or within the particular park property. However, with the design of this comprehensive storm sewer system, not only is it necessary to provide an outlet to maintain a controlled stable water elevation, it is necessary to restrict APRC KEN VRAA DECEMBER 2, 1986 PAGE 2 riparian property with a drainage /ponding easement to incorporate a temporary high water "bounce" that will periodically occur with high intensity or long duration rainfalls. The height of this bounce is dictated by the restriction of the storm sewer outlet capacity in relationship to the greater amount of tributary surface water runoff and /or upstream pond discharges. Due to these three variables, each drainage basin has unique characteristics regarding the impact that this temporary high water elevation has on the surrounding property. Previously, I mentioned that the majority of the park land is presently serviced with a storm sewer system and /or drainage basin. However, there are several parks that currently do not have its ultimate storm sewer system installed, listed as follows: Country Home Heights (HP -4) Highview (H -f) Wescott Station (JP -16, 17 and 18) Rahn Park (AP -49) Highline Trail /Mallard Park (BP -6) Berry Patch (JP -7) 1 Northview (JP -34) 2 Schwanz Lake (LP -32) 1 Oak Pond Hills (LP -61) 1 1 Projects presently approved by Council action with construction anticipated to be completed by June, 1987. 2 Public hearing scheduled for December 18, 1986. With the exception of those projects presently scheduled for storm sewer facilities, the remainder of the parks have not indicated a pressing need to have the extensive and expensive storm sewer systems installed, resulting in the ever unpopular special assessment against property within the affected drainage district. APRC KEN VRAA DECEMBER 2, 1986 PAGE 3 The City has had a very aggressive schedule in installing major trunk storm sewer systems to keep up with the explosive growth of the City and trying to protect existing park land. Within the past 4 -5 years, major storm sewer outlets have been provided for the following park lands: Blackhawk Park Burr Oak Park O'Leary Park Patrick Egan Park Walden Heights Park As can be seen, the majority of the past park land dedication has incorporated major wetlands or drainage basins as a part of the park land itself. Subsequently, with the completion of the trunk storm sewer system and the saturation development of the community, these drainage basins located within various park lands will periodically "bounce" to varying degrees, depending upon rainfall intensity impacting adjacent park land facilities and vegetation on a temporary basis until the storm sewer system can drain it down to its controlled elevation. As you can see, the City has tried to incorporate as many ponding areas as possible to minimize the impact on any given pond. During those periods of most severe rainfall where park land will be most impacted, there will be major flooding in other portions of the City (backyards, street intersections, etc.). To design the system any other way would have resulted in considerable greater expense. Subsequently, a realistic design was incorporated whereby mainline storm sewer laterals were designed to handle the 5 -10 year frequency storms, with major ponding areas designed to handle the infrequent 100 year frequency designs. 1 will look forward to explaining this comprehensive storm sewer system in greater detail with the Advisory Parks Recreation Commission and any other interested party and how it impacts and benefits various park lands throughout the City. For those park lands that presently need storm sewer outlet facilities, it would be very helpful to have the Advisory Parks Recreation Commission evaluate those park lands and provide a priority listing to help the staff in its future capital improvement program planning. Any input and all comments will be greatly appreciated in helping to design the best economical system necessary to service our community. �t J i rector of Public Works TAC /jj Enclosure cc: Thomas L.
