PRIOR TO SSIO MEETING LET ~t 7 1'y .f f MEMORANDUM TO: ADVISORY PARKS, RECREATION & NATURAL RESOURCE COMMISSION 1FROM: KEN VRAA, DIRECTOR OF PARKS & RECREATION DATE: MARCH 31, 1992 RE: THURSDAY, APRIL 2, 1992 COMMISSION MEETING The regular Commission meeting will be preceded by a recreation sub-committee meeting beginning at 6:00 P.M. The regular meeting will commence at 7:00 P.M. in the Council chambers. AGENDA The Agenda for April 2, 1992, is relatively light and should be a short meeting for the Commission. One of the development proposals initially scheduled has been withdrawn and does not appear until the May meeting. One of the first items on the Agenda is the Great Oaks Addition by Robert Engstrom Companies. The Planning Department packet is enclosed for your review. OLD BUSINESS The first item under "Old Business" is the boulevard planting study for Wescott Road. As way of background, the Advisory Commission several months ago, asked staff to review if it was feasible to extend planting along the boulevard area on Wescott. This item will be discussed by the staff. NEW BUSINESS There are two items under "New Business" that request the Advisory Commission to pass resolutions and recommendations of support on to the City Council concerning Arbor Day and B-Bop to Work. B-Bop to Work is a State Program encouraging people to use alternate ways to go to work such as walk, car-pool, or bike on May 19, 1992. WATER QUALITY Water Quality Coordinator, Rich Brasch, will bring you up-to-date on the Deerwood Ponds Addition, which the Commission looked at last month. You will recall that the Commission directed staff to work with the developer to come to a resolution on that issue. COMMISSION MEETING - APRIL 2, 1992 PAGE TWO At the last Commission meeting, members asked that staff review the amount of sand that was placed on City streets and the percentage of sand that is picked up from the street sweeping operations. Staff has been working with Street Superintendent, Erhart, in regards to this and we will be discussing this information with the Commission. OTHER BUSINESS AND REPORTS There are several items under "Other Business and Reports" for the Advisory Commission, although none of these are in depth items, they should be informative for the Commission members. If members of the Advisory Commission are unable to attend the meeting, as always, they are requested to alert staff prior the evening's meeting.

Adjournment MINUTES OF A REGULAR MEETING OF THE ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION EAGAN, MINNESOTA MARCH 5, 1992 A regular meeting of the Advisory Parks, Recreation and Natural Resources Commission was called to order at 7:00 p.m. on Thursday, March 5, 1992 with the following Commission Members present: Jonathan Widem, Ted Billy, Deborah Johnson, Dan Mooradian, Lee Markell and Kevin Knight. Commission Members Erin Ipsen and Jack Johnson were not present. Staff present included Ken Vraa, Director of Parks and Recreation; Stephen Sullivan, Landscape Architect/Parks Planner; Dorothy Peterson, Superintendent of Recreation; John VonDeLinde, Parks Superintendent; Rich Brasch, Water Resources Coordinator; Mike Ridley, Project Planner and Cherryl Mesko, Secretary. AGENDA Deborah Johnson moved, Dan Mooradian seconded with all members voting in favor to accept the agenda as presented. MINUTES OF REGULAR MEETING OF FEBRUARY 6, 1992 Page 7, Paragraph 6, first line should read, "Jack Johnson asked if there....". Paragraph 8, first line should read, Vraa responded yes." Dan Mooradian moved, Deborah Johnson seconded with all members voting in favor to accept the regular minutes of February 6, 1992 as amended. TOWN CENTRE 70 12TH ADDITION - MIDWEST RESTAURANT ASSOCIATES Ted Billy moved, Kevin Knight seconded with all members voting in favor to make the following recommendations to the City Council regarding Town Centre 70 12th Addition. 1. The proposal be subject to a cash parkland dedication. 2. The proposal be subject to a cash trailway dedication. 3. The proposal be subject to a cash dedication of $10,710 to satisfy water quality requirements. DEERWOOD PONDS ADDITION Project Planner Mike Ridley introduced this item as an application for a Comprehensive Guide Plan Amendment from D-III to D-I, a Rezoning of approximately 17 acres from PD/R-3 to a straight R-1 removing the Planned Development zoning and a Preliminary Plat consisting of 28 single family lots. The site is located north of Diffley Road and west of Pilot Knob Road. Landscape Architect/Parks Planner Sullivan explained that the park dedication for this PD was to be a land dedication at the time of platting, however the Knob Hill Planned Development Agreement has since expired, therefore eliminating the previously approved parkland dedication obligation. Steve reminded the Commission that they had previously studied this area and concluded that a park may potentially be located within the area north or west of this parcel. He continued that the park need and location would be determined based on future defined land use and population concentrations. Deerwood School is within this park service area which provided some park benefit and the potential for improvement to the existing elementary site may provide opportunities for a combined neighborhood/school park site. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF MARCH 5, 1992 MEETING PAGE 2 Mr. Sullivan continued that the developer has taken a very positive approach to tree preservation including downzoning, custom grading approach, use of private access roads and utilization of tree protection fencing. By using the custom grading approach, staff will have the opportunity to review each lot before grading is done on the site. Water Resources Coordinator Brasch reviewed the water quality Issues for the Commission explaining that the runoff generated by the proposed development will eventually reach Blackhawk Lake, approximately one mile down drainage. Rich continued that the proposed development contains all or part of several existing wetlands on site which will remain intact and will receive some stormwater runoff from the development. The original recommendation for this development was to raise the normal water level of the larger southern cell of pond BP-27 by one foot to elevation 886.75, and increase the wet storage volume of the small northern cell of pond BP-27 by .75 acre/feet. Additionally, the outlet on the southern cell of pond BP-27 would include a skimmer. Mr. Brash stated that the developer's engineers ran into some problems with increasing the normal water level and have asked to meet with staff on Friday, March 6 to see if some resolution can be agreed upon. Lee Markell asked what the impact would be to vegetation if the pond level was increased by one foot. Rich responded that he had not been able to make that determination to date because of the current ice cover. Ted Billy asked if the water quality issue should be tabled until after the March 6th meeting between staff and the developer. Ken Vraa responded that this development will be presented to the City Council on March 17th and suggested that the Commission make a recommendation regarding parks and trails dedication even If they table the water quality issue. Mr. Clarence Kemp asked that the Commission make a recommendation on the water quality issue based on the results of staff's meeting with him and the engineers on March 6th. Rich Brasch stated that the Commission may want to consider a water quality recommendation that stated to the degree the wet pond volume cannot be expanded, a cash dedication would be required. Rich continued that the Commission may have several options; on site ponding could be required to take advantage of existing ponds, a cash contribution could be required, or the Commission may look at a combination of those options. After further discussion, Ted Billy moved, Deborah Johnson seconded with all members voting in favor to make the following recommendations to the City Council regarding Deerwood Ponds Addition. 1. The proposal be subject to a cash parkland dedication. 2. The proposal be subject to a cash trails dedication. 3. The developer submit a tree protection plan, which denotes woodland masses by general type and size. The plan shall indicate tree protection fencing area for the initial custom grading. The plan shall be prepared, reviewed and approved by staff prior to final platting. 4. The. developer provides tree protection fencing for each lot which Is to be reviewed and approved by City staff at the time of building permit application. 5. The water quality portion of this proposal be tabled pending the results of staff's meeting with the developer and engineers on March 6, 1992. INDEPENDENT SCHOOL DISTRICT #196 - ELEMENTARY SCHOOL #17 Project Planner Mike Ridley introduced this Item as a Comprehensive Guide Plan Amendment from D-1 (Single Family) to PF (Public Facilities), a Rezoning of 15 acres from AG (Agricultural) to PF (Public Facilities, and a Preliminary Plat consisting of one lot and one Outlot for an elementary school located along the south side of Wescott Road and east of Denmark Avenue in the NE 1/4 of Section 22. Mike continued that the Advisory Planning Commission had denied all 3 requests at their February meeting and this item has been continued to the March 17, 1992 City Council meeting. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF REGULAR MEETING OF MARCH 5, 1992 PAGE 3 In addressing the parks and trails dedication issues, Steve Sullivan stated that approximately 50% of this site is wooded. The site program for the elementary school Includes a 78,965 square foot building, 98 car parking lot, service area, trails, two softball/soccer field overlays, hard surface play area and playground. The south 50 feet of the parcel is consumed by a Williams Brothers Pipeline easement. Steve continued that public facilities are not subject to parks dedication, however, the recommended cash trails dedication amount equates to $12,810.00. Another issue presented for the Commission's review was that of tree preservation. Steve noted that of the 15 acre school site, approximately 5.5 of the 7.5 acres of woodland will be removed. It was noted that at each meeting City staff has expressed concern regarding the amount of tree loss. The School District has responded by revising the layout and grading to preserve significant oak trees along their westerly property line. Steve continued that the tree loss is a direct result of a realistic, but land consumptive, site program required for school facilities. Because the recreational facilities will be placed on a rolling site, additional grading needs to occur causing additional tree loss resulting In the limited acreage, site program and rolling terrain not being compatible in providing extensive woodland preservation. After reviewing specific areas where significant trees will be impacted, Steve stated that there can be some preservation based on grading manipulation. In conclusion, Steve stated that staff recommends that the School District review individual tree preservation prior to final platting. Water Resources Coordinator Brasch reviewed the water quality issues for the Commission. He stated the Commission would need to review and make a recommendation regarding whether the development should be subject to a ponding requirement or a cash dedication requirement to meet the water quality standards. He noted that stormwater runoff from the site will be discharged first to Pond JP- 11.1, will flow through two other intervening ponds and then be discharged to Fish Lake. Rich reminded the Commission that Fish Lake does not currently meet its designated Class I direct contact recreation lake classification. It was noted that normally, on-site ponding would be preferred on this site, however, school district officials feel there is not sufficient space on the site to accommodate a pond of this size, provide for adequate tree protection and still meet school district guidelines for play fields. In addition, there is one large nutrient basin between the discharge point for the schools stormwater and the nearest downstream recreational water body where modification could be made to Improve treatment efficiencies. In conclusion, Rich suggested the Commission consider requesting a cash dedication of $14,510 to satisfy water quality requirements. Kevin Knight asked if consideration was given to providing ponds of various sizes to accommodate the water quality considerations. Eric Linnear of Wold Architects responded that if ponding was required on site it would require considerable tree loss. Lee Markell asked what type of modification would be made to the downstream pond. Mr. Brasch responded that this pond is served by a lift station so the thought is to build a suspended inlet that would keep the port 2 feet above the bottom of the pond. Ted Billy suggested that this appeared to be an issue of on-site ponding versus tree preservation. Rich Brasch added that it was actually ponding versus playing fields to meet the criteria for School District 196. Kevin Knight asked what the district's criteria was for playing fields. Mr. Unnear responded that the school will have a population of 775 students which would require two soccer fields and two softball fields. He added that the school district had provided for a softball overlay on a soccer field to help preserve 85 feet of trees. He continued that this compromise was the best the school district could provide. Dan Mooradian asked if on-site ponding would be an option of future development sites near this proposed development to which Rich Brasch responded affirmatively. Lee Markell asked if there were other sites the school district had looked at before deciding upon this one. Mr. Linnear responded that the need for a school was between Deerwood and Woodland elementary schools and this was felt, by the district, to be the best site. ADVISORY PARKS RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF REGULAR MEETING OF MARCH 5, 1992 PAGE 4 Lee Markell asked If retaining walls could be used in other areas on the site to help preserve some of the vegetation. Mr. Unnear stated that they are looking at the option of installing a retaining wall on the west side of the west playing field to preserve trees. Steve Sullivan added that additional trees can be saved by retaining walls, however the question is what would be the dollar expenditure needed to preserve them. There also is a three foot high maximum size that can be used for retaining walls when planned in an area where there will be so many children. After further discussion, Ted Billy moved, Lee Markell seconded the motion with all members voting in favor to make the following recommendations to the City Council regarding Independent School District 196 - Elementary School #17. 1. The proposal be subject to a cash trails dedication. 2. The School District evaluate and submit to the City, prior to Final Plat, tree specific preservation revisions. 3. The proponent submit a tree protection plan to the City prior to Final Plat. 4. The development be subject to a cash dedication of $14,510 to satisfy water quality requirements. MEGHANS ADDITION - PULSAR INC. Project Planner Mike Ridley introduced this Item as a Comprehensive Guide Plan Amendment from Neighborhood Business to D-III (Mixed Residential, 6-12 units/acre), a Rezoning from Neighborhood Business to R-4 (Multiple Family), and a Preliminary Plat consisting of 13 townhouse lots on 10.6 acres. The site is located at the SE Intersection of Diffley Road and Nicols Road. Rich Brasch addressed the water quality issues for this development explaining that this proposed multi-family residential development lies In the lower reach of drainage basin A. He continued that approximately 8.6 acres of the site will discharge to a storm sewer along Nicols Road with the remaining 2 acres discharging stormwater to the northeast to the existing storm sewer system on Diffley Road. This will eventually drain to Pond AP-39 which is located in between the railroad tracks and the Minnesota River along Nicols Road and is classified as a sedimentation basin. Mr. Brasch continued that on-site ponding is feasible for that portion of the development that will discharge to the storm sewer along Nicols Road and in order to provide adequate treatment the pond would need to provide a minimum wet volume of .81 acre/feet, minimum surface area of .31' acres and a minimum average depth of 2.6 feet. Since on-site ponding would not be feasible for the remainder of the site, Rich suggested the Commission consider a cash dedication of $2,260 for the remaining 2 acres. Relative to the parks dedication issue, Director Vraa explained that the development was zoned neighborhood business sometime prior to the 1970's when the Cedar Grove Addition was platted and developed. After reviewing all available files, staff has found no indication that parks dedication was ever fulfilled at the time this parcel was platted. Ken continued that the developer has expressed some concerns over how the rate for parks dedication would be calculated, asking specifically if the rate would be $559 per unit as is represented in the 1992 fees. The developer has expressed the opinion that $559 per unit exceeds the general guideline of 10-12% for parks dedication based on the current value of their property. Mr. Dave Sellergren, representing Pulsar Inc., addressed the Commission by reviewing the general guidelines for parks dedication policies. He stated that the Statute allows the City to have the option of requesting either cash or land dedication from a developer. He continued that most cities say that 10% is a reasonable dedication amount but the option remains open for negotiation between the city and the developer. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF REGULAR MEETING OF MARCH 5, 1992 PAGE 5 As history, Mr. Sellergren stated that the land was platted years ago and that Cedar Pond Park was dedicated as part of Cedar Grove 1st and 2nd Addition. He argued that this parcel is being re-platted and the question the Commission needs to answer is whether or not the platting requirements were met when this parcel was originally platted for neighborhood business. It was noted that the developer, since appearing before the Advisory Planning Commission, had reduced the number of units from 104 to 88 to help mitigate some of the concerns shared by neighboring residents. Relative to the parks and trails dedication fees, Mr. Sellergren stated that the combined amount of $669 per unit times the 88 units planned equals $58,872, or approximately 19% of the $300,000 land value. The developer Is of the opinion that this percentage far exceeds the general guideline of 10-12%. The developer also felt that the dedication, or deeding, of Cedar Pond Park should be considered the parks dedication for this site since it was given at the time of the original platting of this property. Mr. Sellergren asked that the Commission consider all of these circumstances before deciding what the appropriate dedication would be or if a parks dedication would be necessary. Ted Billy asked what the developer felt was a reasonable solution. Mr. Sellergren stated that the developer has already taken sixteen units out of the project and they would like to see the Commission consider Cedar Pond Park as the park dedication and not ask for further dedication dollars. Jonathan Widem asked what type of units were projected. Mr. Sellergren responded that these were two bedroom units and it is anticipated that there will be less than two people per unit since this type of housing is typically occupied by singles. Dan Mooradian asked if the density exceed what was originally planned. Ken Vraa responded that this site has always been zoned neighborhood business and if that zoning stayed the same the parks dedication impact would be less than the density proposed in the Meghans Addition plat. Ted Billy stated that Neighborhood Business zoning has little impact on parks, whereas changing the zoning to multiple family will have a much larger impact on the existing park system. Deborah Johnson asked for a clarification of the general guideline of the 10-12% park dedication range referenced by Mr. Sellergren. Mr. Vraa responded that this range varies by community but has been a very good gauge. However, not only is this percentage taken into account when determining park dedication but the density of a property is also considered. Ken added that as the density of a parcel increases so does the fee scale. Ms. Johnson then asked what percentage the park dedication fee represented. Mr. Vraa responded approximately 13%. Ms. Johnson continued that she was not persuaded that 13% had a precedent setting impact nor was it much out of the range of the general percentages. Mr. Sellergren added that the 19% figure he was using included both the park dedication fee of $559 per unit and the $100 per unit trail dedication fee. Jonathan Widem asked what the dollar value of Cedar Pond Park was and how big it was. Ken Vraa responded that the park was approximately 10 acres and was deeded, to the City In the 1950's but the City did not have a dedication policy until the 1970's. As a point of clarification, Mr. Sellergren stated that the deed to Cedar Pond Park was given to Eagan two years after the Cedar Grove Addition was platted. Ted Billy suggested that even if the City does not require a parkland dedication, the zoning change of this parcel will most definitely impact the existing Cedar Pond Park. Deborah Johnson asked why the zoning was changed from Neighborhood Business to Multiple Family. Mr. Sellergren explained that the current market for neighborhood business in the community is poor, the volume of traffic at this intersection has changed but the volumes have not grown to the capacity as was once projected when originally platted, the multiple family product would be a better "neighbor" to the existing residential, and the high demand for the product being planned would benefit both the developer and the community. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF MARCH 5, 1992 MEETING PAGE 6 Ken Vraa noted that there were two entire buildings being deleted from the plan. Mr. Sellergren confirmed that information stating that the buildings will then move away from the existing residential area. Ted Billy clarified that the $559 per unit park dedication and $100 per unit trails dedication fee remained the same as the 1991 fees. Jonathan Widem noted that in order to justify a credit for park dedication fees a development would need to show that they would not impact existing recreational facilities and asked the developer what facilities were being planned in this development to lessen the impact on surrounding parks. Mr. Sellergren stated that the developers felt that there would not be an impact to the surrounding facilities since the bulk of the residents are being projected as single women therefore the need for additional facilities, i.e. tot lots, etc. are not necessary. Ted Billy reiterated his concern for setting a precedent, adding that the Commission may find themselves in a position to negotiate with each developer/development if the park dedication fees are changed or waived. Mr. Sellergren stated he appreciated the Commission's concern however he reminded them that the guidelines were set for that reason; as a guideline, but should allow for the flexibility of negotiation. Dan Mooradian stated he did not see enough substantiation to change the parks dedication/trails dedication standards In this case. Both Lee Markell and Kevin Knight concurred. Deborah Johnson stated that being a single woman, the proposed target range for this development, she felt the provision for park facilities should definitely be provided for or be considered with a development of this density. Mr. Sellergren reminded the Commission that the developer is asking them to consider whether a 19% dedication fee is reasonable based on the value of the land. The developer feels that 19% is excessive and not representative of the burden this development would place on the existing park system. Mr. Mooradian stated that the amount of parkland/trails dedication represents the density of the development, not a percentage of the value of the land. He continued that if the density were lower the dedication fees would be lower. The dollar amount reflected as parks/trails dedication reflects the developers desire to change the zoning and density of their property. After further discussion, Deborah Johnson moved, Dan Mooradian seconded the motion with all members voting in favor to make the following recommendations to the City Council regarding Meghans Addition. 1. The development be responsible for parks dedication fees at a rate of $559 per unit. 2. The development be subject to a combination of on-site ponding requirement to treat the 8.6 acres of the site that drains to Nicois Road and a cash dedication for the remainder of the site. The pond should be constructed according to National Urban Runoff Program design standards and should provide a minimum wet volume of .81 acre/feet, minimum surface area of .31 acres and a minimum acreage depth of 2.6 feet. In addition, a cash dedication of $2,260 should be required to meet the water quality requirements for the remainder of the site. 3. The development be responsible for trails dedication fees of $100 per unit only if, after investigation and confirmation by staff, it is determined that trails/sidewalk assessments have not been levied and paid for this development. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF REGULAR MEETING OF MARCH 5, 1992 PAGE 7 RESOLUTION SUPPORTING STATE & FEDERAL OUTDOOR RECREATION GRANTS FUNDING John VonDeLinde introduced this Item explaining that the MRPA is asking communities in Minnesota to enter into resolutions supporting continued funding and enhancement of Federal and State Outdoor Recreation Grant Programs to local units of government. Mr. VonDeLinde then reviewed the draft resolution providing a brief description of the State Outdoor Recreation Grant Program and Federal Land and Water Conservation Fund (LAWCON) Program. Some of the grants for parks acquisition and development the City of Eagan has received In the past include such parks as Blackhawk, Trapp Farm, Thomas Lake, Patrick Eagan, Fish Lake and Rahn Athletic Parks. Because the funding through LAWCON and state programs has dwindled significantly it is felt that with the solidarity of many communities in the state expressing a similar view perhaps funding can continue. After further discussion, Jonathan Widem moved, Lee Markell seconded the motion with all members voting in favor to approve the adoption of the proposed resolution urging the continuation and expansion of the Federal Land and Water Conservation Fund and State Outdoor Recreation Grants Program. RESOLUTION ON WATER QUALITY - WESTON HILLS Rich Brasch explained that on February 14, 1992, representatives from the departments of Planning and Community Development, Public Works and Parks and Recreation met with the developer and the two riparian landowners on Pond LP-27 who had expressed concern about the water levels In the pond. At that time a verbal agreement was reached among all participants that storm water from the treatment pond in the Weston Hills development would be routed south to LP-27 with the understanding that the necessary ponding easements were to be given to the City, that an outlet would be installed on LP-27 and that appropriate trunk storm sewer charges would be made to benefitted properties consistent with the policies established by the City Council. The City Council reviewed this development at their March 4, 1992 meeting. After the Council's review and recommendations, the riparian owners withdrew their approval to allow storm water to flow to the south to Pond LP-27. Initially these owners were uneasy about being assessed for the proposed pond improvements, but after the Weston Hills development was reviewed by the City Council the riparian owners were soured over other issues not related to the ponding. Dan Mooradian suggested that the best case for the residents was to bring the storm water to the south but understood their desire not to be assessed. He stated he wasn't clear why they would be willing to subject this wetland to drought because of other issues arising from the City Council meeting. Ted Billy noted that there appeared to be no other option than to drain the stormwater to the north. Deborah Johnson asked if the decreased water level was attributed to natural causes. Rich Brasch responded that the natural drainage is being shifted because of the development. Lee Markell asked If the majority of the drainage could go to the north with a portion directed to the south. Mr. Brasch responded that for the drainage from the development to run both north and south the developer would need to run storm sewer both north and south to allow for that option. If that did become an option, the riparian owners would still need to provide an easement which they are unwilling to do at this point. After further discussion, Ted Billy moved, Deborah Johnson seconded the motion with all members voting in favor to make the following three priority recommendations to the City Council regarding water quality issues for Wescott Hills. 1. First priority would be to have the storm water drain to the south into Pond LP-27- 2. Second priority would be to have the storm water drain to the north. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF MARCH 5, 1992 MEETING PAGE 8 3. Third priority would be to have the storm water drain to the north and if enough water can be added by overland flow to the wetland so as not to dry Pond JP-27 (without causing a problem of flooding), this option should be considered. DEPARTMENT HAPPENINGS Some of the items reviewed by Superintendent of Recreation Peterson included the dosing of the ice rinks and tubing hill for the season, the beginning of adult softball registration and the successful completion of the bandy program. Another issue brought to the Commission's attention Included the projected increase in EAA's summer programs; 50% increase in travel baseball and softball,.38% increase in bantam soccer, 24% increase in travel soccer, and 17% increase in-house baseball. Dorothy reviewed the facilities that will not be ready for use in summer, 1992. Superintendent of Parks VonDeLinde reviewed several items relative to the maintenance Issues including resuming construction of Trapp Farm playground, construction of athletic field benches, picnic tables and park identification signs and the ongoing risk management program. John also commented that the City has received the designation of Tree City USA for the fifth consecutive year as well as being presented with a Growth Award. The most recent forestry brochures were given to Commission members and John explained that plans have begun to add two more to the series. Ted Billy asked about the widening of Diffley Road near the proposed Caponi Art Park and asked how traffic could be linked from Goat Hill and Lexington/Diffley park sites. Director Vraa stated the County Is looking at the possible option of a tunnel under Diffley Road to accommodate access to the proposed park, however, the County will not assume any financial obligation for the installation of such a tunnel. In response to another question from Mr. Billy, Ken Vraa responded that U.S. West will be installing a 36 x 12 building to house communication equipment at the Lexington/Diffley site. He noted that staff will be provide input as to the type and style of building that will be placed near the water reservoir. Lee Markell suggested consideration be given to preparing a brochure that speaks to tree preservation from a homeowners perspective rather than a developer's. Deborah Johnson indicated she is shocked to see how developers clear sites for development and is impressed at the importance that is now being placed on vegetation preservation. ICE ARENA/SWIMMING POOL UPDATE Director Vraa reviewed the ice arena/swimming pool plans as presented to the City Council on March 2, 1992. Ken indicated that the plans are only conceptual at this point and after further study there may be some changes made. The plans reviewed for the Commission members included site plans, swimming pool layout and ice arena layout. The projected construction costs forthis project, including contingency, is approximately $5.6 million of which the City will contribute $1.3 million toward the project. Mr. Vraa stated that there is a group of residents who have organized and will begin approaching local corporations for sponsorship and support. The Council has set a referendum date of May 19, 1992 but have not set a bond amount to date. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF REGULAR MEETING OF MARCH 5, 1992 PAGE 9 JOINT MEETING WITH CITY COUNCIL Mr. Vraa stated that the City Council has asked for a joint meeting with the various commissions and has proposed a meeting date of March 31st. The Council has no specific agenda at this time but would like this to be a "give and take" situation where the Commissions and Council can see what issues may need to be addressed in the future. On item the Council will want to pursue with the APRNRC is water quality information. Ken asked that If any Commission Members had items they would like discussed they should get in touch with him so he can pass them on to Tom Hedges to be included on the agenda. ROUND TABLE Dan Mooradian commented on the I.S.D. #196 new school proposal. He continued that the main issue appeared to be a trade-off between on-site ponding to preserve water quality versus tree preservation. Dan felt that a high priority should continue to be placed on tree preservation. Lee Markel) asked if staff knew why the streets are sanded so heavily In the winter. His concern is for the high level of sand that is washed into the storm sewer system and ends up in the city's water bodies. He asked if the sand could be recycled in some way. Mr. Markell also asked staff If there was the potential for providing a canoe access on the west end of Hay Lake. He noted that since the large hill had been graded down the lake is more visible and people may want to access the lake with their canoes. Lee asked if staff could look into the feasibility of this request. With no further business to conduct, Lee Markell moved, Dan Mooradian seconded the motion will all members voting in favor to adjourn the meeting. The meeting was adjourned at 9:40 P.M. S c etary Date MEMORANDUM TO: ADVISORY PARKS, RECREATION & NATURAL RESOURCE COMMISSION FROM: STEPHEN SULLIVAN, LANDSCAPE ARCHITECT/PARK PLANNER DATE: MARCH 19, 1992 RE: GREAT OAKS ADDITION - ROBERT ENGSTROM COMPANIES PROPOSAL An application has been submitted requesting a Comprehensive Guide Plan change from D-3 multiple family to D-1 single family. The proposal also requests the rezoning from R-4 to R-1 and the preliminary platting of 29 lots on approximately 20 acres. BACKGROUND The parcel is located west of Elrene Road approximately 1/4 mile south of Yankee Doodle Road. The subject property is part of the Woodlands North Planned Development. FOR COMMISSION REVIEW The Commission will need to review and make recommendation regarding the following items: 1. What is the Parks Dedication obligation? 2. What is the Trails Dedication obligation? 3. What is the impact to the Woodland resource? ITEM #1 PARKS DEDICATION Great Oaks Addition preliminary plat is within Neighborhood Park Service Area #14 and is served by Mueller Farm Park. Wescott Station Park will also provide service benefit to this subdivision. The Woodlands Planned Development agreement provides for a cash parks dedication based on the rate schedule at the time of final plat. ITEM #2 TRAIL DEDICATION The proposal will be subject to a cash trails dedication. GREAT OAKS ADDITION PAGE TWO MARCH 19, 1992 ITEM #3 IMPACT TO WOODLAND RESOURCE The site is characterized by knob & kettle topography with moderate to steep slopes. Woodland masses are located along Elrene Road, within the southeast comer of the parcel and along a ridge line central to the west property line. The developers approach utilizing large lots, low residential density and custom grading preserves a majority of the significant trees. The woodland mass adjacent to Elrene Road is primarily oaks and birch. The grading plan indicates minimal impact to this woods. The future grading of house pads and driveways will result in some tree loss. The woodland area within the southeast corner of the parcel is comprised of mature oaks setting on the north face of a knoll. The grading plan indicates removal of approximately a 30' X 70' woodland area as a result of a cul-de- sac extension. This tree loss could be minimized by either shortening the cul-de-sac length or off-setting the cul-de-sac head to the west. The proposal places Lots 3, 6 & 7, Block 1, over this woodland area. The oaks are located on a 25% gradient with a clearing at the top of the knoll approximately 30' above the cul-de-sac. Lots 6 & 7 gain access directly from the proposed cul-de-sac. Staff is concerned that grading of driveways and house pads could result in significant tree loss on Lots 6 & 7. Staff requests that the developers provide schematic lot lay-outs for these two lots for review and approval by the City prior to final plat. The woodland along the west property line is primarily oaks, birch and black cherry. An area 60' X 100' of woodlands is to be removed as a result of a side slope for an adjacent cul-de-sac road. The developer has assured staff that these trees will be saved with revision of the development plan. Staff recommends that the developer evaluate the revision of the road alignment, grade and/or utilization of retaining walls to minimize the impact to this woodland. The development includes a reforestation plan proposing the planting of over 100 - 1-1/2" deciduous overstory, evergreen and ornamental trees. The proposal did include a' generalized tree survey as part of the landscape plan. Staff recommends that this plan be revised to include tree protection fencing in areas where grading occurs adjacent to the significant woodlands. In summary, the down zoning, custom grading approach and utilization of tree protection fencing is an appreciable effort in preserving the tree resource. The developer's commitment to sensitive architectural compatibility, site planning and builder sensitivity, although not by City authority, is essential in assuring a complete effort in preserving these significant woodland areas. /6. GREAT OAKS ADDITION PAGE THREE MARCH 19, 1992 FOR COMMISSION ACTION The Commission may consider the following recommendations: 1. The proposal shall be subject to a cash parkland dedication. 2. The proposal shall be subject to a cash trails dedication. 3. The developer revise the easterly cul-de-sac to preserve additional woodland area. 4. The developer provide a schematic layout/grading plan for Lots 6 & 7, Block #1, for City review and approval prior to final plat. 5. The proponent revise the layout of the west cul-de-sac roads to minimize impact to the adjacent woodland. The revision shall be reviewed and approved by City staff prior to final plat. 6. The proponent revise the landscape plan to include tree protection fencing. The revised plan shall be submitted and approved by City staff prior to final plat. 7. The developer provides tree protection fencing for each lot to be reviewed and approved by City staff at the time of building permit application. SS/bls /7. MEMO TO: ADVISORY PARKS, RECREATION, AND NATURAL RESOURCES COMMISSION FROM: RICH BRASCH, WATER RESOURCES COORDINATOR DATE: MARCH 23, 1992 SUBJECT: WATER QUALITY REQUIREMENTS FOR GREAT OAKS ADDITION - ROBERT ENGSTROM COMPANIES PROPOSAL This preliminary plat application is for a single-family residential development consisting of 29 lots on 17 acres, located west of Elrene Road in the northeast quarter of section 14. The land now is zoned for multi-family residential development, so a change in zoning to single-family residential development has been requested as well. FOR COMMISSION REVIEW The Commission will need to review and make a recommendation regarding whether the development should be subject to a ponding requirement or cash dedication requirement to meet water quality standards as set by the City in its water quality management plan. WATER QUALITY ANALYSIS This 17-acre, single-family residential development lies in the upper reach of Drainage Basin J (Figure 1). While there are no recreational-classed water bodies immediately down drainage, Fish Lake lies at the lower end of this drainage. Fish Lake does not meet the direct contact recreation water quality standards set for it in the City's water quality management plan. On-site ponding to meet water quality standards is both desirable and feasible for this site. Analysis using the City's water quality model indicates that the developer will be able to use two natural depressions on the site to create ponds that will meet treatment standards (Figure 2). The larger of the two depressions lies in the west central portion of the site and could be excavated to provide a pond with a surface acreage of about .3 acres and a wet pond volume of .8 acre-feet. This pond would serve about 10.6 acres of the site. The other depression lies in the east central portion of the site and could be excavated to provide a pond with a surface area of about .13 acres at normal water level and a wet pond volume of about .31 acre-feet. This pond would serve an additional four acres of the site. Together, these two ponds will intercept and treat runoff from virtually all impervious areas within the proposed development. Drainage from the remainder of the site (approximately three acres) will be from treed areas and backyards. This small 1 /9. amount of drainage easily can easily be accommodated by existing off-site ponds. STAFF RECOMMENDATION Staff recommends that the development meet its water quality treatment requirements by creating two treatment ponds on-site that meet the surface acreage and minimum volume standards identified in the above narrative.

That study concluded that, of the 84 miles of boulevard included in the evaluation, only about 3.4% (or 4 miles) met the minimum geometric standards for boulevard landscaping. In addition, this study did not take into consideration the presence of underground utilities which could further restrict the viability of such a program. At the November meeting the Commission concluded that a functional and cohesive master street tree planting program would not. be possible given the restrictive green spaces adjacent to the city's collector and arterial streets and along county highways. In the final analysis, the Commission determined that the best opportunities for boulevard planting would probably be along a few selected city streets or along future expansions to the county highway system. In order to keep the planning process moving forward (if even on a limited basis) the Commission gave direction to staff to examine in greater detail the feasibility of developing a "streetscaping" program along Wescott Road between Pilot Knob Road and Lexington Avenue. This particular segment offers some of the widest and most aesthetic boulevard area within the city's street infrastructure. In response, staff have prepared this report analyzing potential planting alternatives within this portion of Wescott Road. The report will include an evaluation of each of the boulevard segments sharing common characteristics (with respect to planting area and underground utilities), provide an overview of alternative planting schemes, present a preliminary planting budget, and discuss several limiting factors which were discovered during the evaluation. EVALUATION APPROACH In early March the Forestry Department contacted the appropriate utility companies to request utility locations along Wescott Road. Investigations were also made with the city's a~. Engineering Department which revealed that the road right-of-way extends from the center line of the road to a point approximately 12" beyond the back of the trails on both the south and north sides. Consequently the planting area available for boulevard landscaping is essentially that green space between Wescott Road and the appurtenant bike trails and sidewalks. Following that determination, measurements were then taken to establish the location of the various underground utilities within these boulevard "strips." To simplify the recordings of our findings, Wescott Road was broken down into various segments. These segments do not necessarily stop or start in driveways or street intersections, but wherever characteristics of the boulevard change from one area to the next. The following discussion presents an analysis of the geometrics and utilities common to each of these sections. BOULEVARD ANALYSIS - SOUTH SIDE L Pilot Knob Jo Library The boulevard is a consistent ten feet in width from Pilot Knob Road to the east driveway entrance to the Dakota County Library. Planting in this area would be impossible since there is a telephone line approximately six feet back of curb and there is an electric line that runs approximately 8 1/2 feet behind the curb. As the Commission may recall, under current regulations, trees cannot be planted within two feet of any underground utility of four feet within a trail or sidewalk. 2 Library to Denmark Avenue On the south side of Wescott Road from the eastern driveway entrance to the Dakota County Library to Denmark Avenue, the grassy boulevard strip is a consistent twelve feet in width. Here again, the telephone line runs six feet back of curb, and the electric line runs approximately 8 1/2 feet behind curb. Based upon the same limitations, this is an area that also cannot be planted between the curb and the trail. However, because the city has the landscaping responsibilities for the Municipal Center and Dakota County Library "campus", it may be possible to do some plantings of overstory trees, or ornamental trees on the south side of the bituminous trail, but not between the street and the trail. From the library eastward, everything on the south side of the trail is private property. While there may be some opportunities to plant there, it would require the acquisition of planting easements from the adjacent property owners. Denmark Avenue to Lexington Avenue From Denmark Avenue eastward to Lexington Avenue the boulevard on the south side of Wescott Road is 14 feet wide. While this would indicate that we might be able to do some planting based upon the ten foot setback from the street, and four foot minimum setback from the trail, there are again significant conflicts with underground utilities. There is a major telephone line that runs down the center of the boulevard strip varying between seven feet and 11 feet from the back of curb. Therefore it appears that the only viable planting opportunity would be on the south side (property side) of the bike trail. However, this again would require the cooperation of the adjacent property owners. BOULEVARD ANALYSIS - NORTH SIDE L Lexington Avenue to Pilot Knob Road The north side of Wescott Road, between Pilot Knob Road and Lexington Avenue, can be considered as one contiguous segment. Throughout this area the boulevard is a consistent 17 feet in width. There is an underground gas line that runs the entire length of this segment approximately three feet behind curb. Essentially then, there is a 14 foot wide clear planting zone from three feet behind the curb up to the edge of the sidewalk. However, as the Commission is aware, there are overhead lines that run the entire length of Wescott Road on the north side, so while planting opportunities exist, the plant material would have to be limited to smaller ornamental trees or larger shrubbery. As with the south boulevard, there exists some possibility of planting trees on the outside of the sidewalk, but since this is all private property the City would be required to obtain planting easements from the owners of the adjacent property. As an additional limiting factor, it should be noted that many of the areas adjacent to the trail would be unsuitable for planting anyway because of the existence of the steep slopes, native vegetation, or landscapes which have already been installed. DISCUSSION/ALTERNATIVES It appears as though our hope for having a fully tree-lined boulevard along Wescott Road are unrealistic. This leaves the possibility of exploring a "modified" landscaping program to overcome the limitations imposed by underground utilities and geometric considerations. The first alternative would be to plant understory or small ornamental trees under the power lines along the north side of Wescott Road. If the Commission wanted to create some type of columnar effect staff would suggest using a thirty foot spacing of the trees with uniform placement between the street and the sidewalk, e.g. eight to ten feet behind curb. This approach to planting would require the purchase of about 170 trees. Based on an estimated cost of $90 per tree (e.g. 1-3/4" diameter crab apple,) this would require a capital outlay of approximately $15,300 for this type of planting. The obvious drawback to this approach, of course, is that a singular row of trees on the north side may to cause a distracting imbalance in the boulevard landscape. Users of Wescott Road may well ask why the trees were planted under the power lines on the north side, and the boulevard left bare along the south side. A second alternative is to cluster the trees in small groupings running the length of Wescott Road. Obviously this approach would require fewer trees than a columnar planting. Small groups of trees might be separated from other groups by several hundred feet. This would result in a substantial reduction in financial outlay; it could probably be accomplished in the neighborhood of $5,000 to $7,000. Again it is important to recognize that planting easements would be required in select areas. A third option is to explore the possibility of planting larger overstory trees along the back side of the trail and the sidewalk, on both sides of the road right-of-way. Like the second alternative this approach would require the acquisition of easements for the entire length of the roadway. Another disadvantage of this type of planting is that the trees would end up so far from the street (22 to 26 feet) that the effect of a tree lined boulevard may be so diminished as to render it ineffective. The cost of this alternative would be in the range of $25,000 assuming 250 trees spaced at 40 foot intervals. In summary, staff have concluded that the presence of underground utilities and overhead wires, combined with planting setback requirements effectively negate the establishment of trees on the boulevard strip along the south side of Wescott Road, and restrict the planting to only small ornamental trees within the boulevard on the north side of the road. The development of even a moderately effective landscaping program would require securing of private property easements along portions or all of the Wescott Road right-of-way. FOR COMMISSION ACTION In light of these conclusions and the discussion of alternatives outlined above, staff would appreciate having direction of the Commission as it pertains to the landscaping of Wescott Road. In their discussion the Commission may wish to recommend the following options: 1. To plant understory trees strictly on the north side of Wescott Road, under the powerlines. 2. To obtain private property easements and to plant trees in clusters on areas outside of the city boulevard. 3. To obtain private property easements and to plant trees in a tree lined, columnar form, on those areas outside of the boulevard. 4. To recommend some combined approach of alternatives 2, 3 and 4. 5. To consider some other alternative landscaping concept not addressed in this report, or 6. To take no action, i.e. to leave Wescott Road as it is. Regardless of which "action" alternative appeals to the Commission (if any,) consideration must also be given to addressing the available options for financing the selected landscaping concept. 0 onDeLinde S pen tendent of Parks Tom Schuster City Forester JVK/TS/nab 3b:aprnrc.085 MEMO TO: EAGAN ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: JOHN VONDELINDE, SUPERINTENDENT OF PARKS DATE: MARCH 23, 1992 SUBJECT: ARBOR DAY PROCLAMATION Since the city's first Arbor Day program was held in 1987, the Commission has been asked, each year, to adopt an official resolution in support of Arbor Day activities and tree planting in the community. For the information of the Commission, the Parks and Recreation Department is planning three primary Arbor Day programs this spring. Our City Forester has already been visiting the third grade classes in Eagan's public elementary schools. More than 800 students will be involved in an Arbor Day poster drawing contest and will participate in an entertaining, tree conservation program put on by our City Forester, Tom Schuster. Students will also receive a free seedling to plant at home. This is the fourth consecutive year that this program has been held in the schools; and it is jointly sponsored through public/private partnerships with Franks's Nursery and Crafts and First Bank Eagan. On Saturday, April 25th, the city will be hosting the sixth annual community Arbor Day celebration at Wescott Station Park. It is expected that over 70 volunteers from the community will be involved in this program which includes an official proclamation of Arbor Day, presentation of the Tree City U.S.A. awards, along with the planting of nearly 100 trees and shrubs. The third program, scheduled for Saturday, May 2nd, is the city's fifth annual public tree sale. This year eight varieties of trees will be made available to the public at discount prices. Registrants will be selected during a random drawing to be held following the Commission meeting on April 2nd. 750 trees are planned for sale again this year with about 400 families participating. Taken together, it is expected that more than 2,000 of the community's residents will be involved in some aspect of the city's annual Arbor Day programs. For Commission Action In suppo of these programs and to encourage the general public to plant and preserve trees in our community, the Co ission is graciously asked to adopt the Arbor Day Resolution which is found on the following page. A corn io ' resolution will then be forwarded to the City Council for their adoption on April 21st. ohn K. VonDeLinde Superintendent of Parks JKV/nab Attachment 3b:aprnrc.083 1.

MEMORANDUM TO: KEN VRAA, DIRECTOR OF PARKS & RECREATION FROM: JON OYANAGI, RECREATION SUPERVISOR DATE: MARCH 26, 1992 RE: RESOLUTION SUPPORTING B-BOP TO WORK EAGAN Annually, the Minnesota Department of Transportation sponsors a B-BOP to Work Day in Minnesota. The Governor has endorsed the campaign and in past years the Lieutenant Governor has participated by bicycling with an official caravan to the Capitol. B-BOP to Work Day is scheduled for May 19, 1992. Organizers hope that Minnesotans will bicycle, walk, car pool or bus to work that day as a way to discover the benefits and rewards of alternate transportation. B-BOP stands for bicycle, bus or pool and includes walking, jogging and even roller blading. As a way to promote this event, I am suggesting that Eagan declare May 19, as B-BOP Day. Our support will help to reinforce the goals of the program which are to raise environmental consciousness, create a healthier work environment and increase productivity. Individuals may benefit by saving money on parking, gas and car repairs; reduce stress by avoiding heavy traffic; or improve physical health by walking or bicycling. Flyers are provided to promote the event in our community and lapel stickers are available to reward participants as they arrive at work. Other suggestions are welcome to help increase awareness and participation. Attached is a resolution for the Commission's review. Should they offer their support, we should submit the resolution to the City Council for their review at the April 21 or May 5 meeting.

The initial staff recommendation was to require raising the normal water level of pond BP-27 by one foot and increasing to .75 acre/feet the storage volume of a smaller wetland to the north (pond BP-27.1). Subsequent investigation by the developer's engineer and review by city staff indicated that raising the normal water level in pond BP-27 was not possible without further submerging the storm sewer system that ties into the pond, causing probable maintenance problems. Because a review of the water quality-related requirements was therefore in order, the commission postponed further action on this development until. its April meeting. FINDINGS On Friday, March 6, staff met with Mr. Clarence Kemp of Twin Cities Properties and Brian Johnson of McCombs, Frank, Roos, Associates to discuss revising the water quality treatment requirements for the Deerwood Ponds development. As a result of additional technical analysis, the meeting, and subsequent phone conversations, we arrived at a mutually acceptable recommendation to provide adequate ponding on site. Analysis using the city's water quality model showed that increasing the wet pond volume of pond BP-27.2 to .4 acre-feet of an acre/foot, and increasing the wet pond volume of pond BP- 27.1 to .7 acre-feet will meet treatment standards for the development. In addition, the developer should install a skimmer on the outlet of pond BP-27. The enlarged pond volumes should be achieved by excavation and the designs for the enlarged ponds should conform to NURP standards. Both the skimmer and pond design should be approved by the city. 1 ~S, STAFF RECOMMENDATION Staff recommends that the development comply with city water quality treatment requirements by increasing the wet pond volumes of ponds BP-27.1 and BP-27.2 as identified above and that a skimmer be installed on the outlet of pond BP-27.

VII MEMO TO: ADVISORY PARKS, RECREATION, AND NATURAL RESOURCES COMMISSION FROM: RICH BRASCH, WATER RESOURCES COORDINATOR DATE: MARCH 26, 1992 SUBJECT: RESPONSE TO COMMISSION INQUIRY REGARDING CITY SANDING/SALTING OPERATIONS At it's March meeting, the Parks, Recreation and Natural Resources Commission requested that staff look into road sanding and salting activities within the city limits and the water quality implications associated with those activities. The following are answers to questions that arose during the discussion of this topic as well as answers to related questions that might prove helpful. Question #1: Who conducts sanding and salting operations and street sweeping activities within the city? Response: The Street Division within the Department of Public Works conducts these operations on all city streets excluding those that are also county highways. The Dakota County Department of Highways generally conducts these operations for county highways bisecting the city, including Lexington, Yankee Doodle, Pilot Knob, Diffley, Cliff, and Lone Oak Roads. Personnel from the Department of Parks and Recreation sweep the city's bituminous trail system. Finally, Minnesota Department of Transportation sands, salts, and sweeps state and inter-state highways within the city. Question #2: Are records kept of the amount of sand and salt spread on city streets as well as for the amount of debris picked up through street sweeping operations? Response: The Street Division with the Department of Public Works keeps records of the volume of sand and salt applied for snow and ice removal as well as the volume of debris picked up through sweeping operations. Dakota County has no similar records for county roads within the City of Eagan. 1 Question #3: What do those figures show? Response: Attachment 1 shows estimated amounts of sand and salt applied and sweepings collected by the City of Eagan street crews for the years between 1985 and 1991. Estimates of sand/salt mixture applied as well as sweeping collected are based on the number of truckloads of known capacity involved in handling the materials for each type of operation. The data show that the city removes about 94% of the total weight of non-salt mixture applied to roads for snow and ice control. The majority of debris collected by sweeping is probably sand from winter sanding operations, but the figures also include material originating from other sources such as erosion and airborne deposition. Road sanding and salting figures for 1991 indicate there was significantly less sand/salt mixture per inch of snowfall applied to city roads than in other years for which records are shown. While the city has made a concerted attempt to use less road sand and salt in response to environmental and cost concerns, the best explanation for the drop is that most of the precipitation this winter occurred during two large storm events which were handled primarily by street plowing. Snowfalls of 2" or less or generally handled by sanding and salting only while those over 2" are handled by street plowing and may be supplemented by sanding and salting operations. Under current policies, heaviest applications of sand and salt occur when there are a high number of snowfall events that drop small amounts of snow. Question #4: Is sand and salt used at a heavier rate in Eagan than in other communities? Response: The amount of sand and salt used by the City of Eagan is determined by many variables including topography, the number of major intersections and arterials, and the frequency and depth-of snowfall. We are currently checking to compare the amounts of sand/salt mixture applied per mile of roadway by Eagan with the same figures for other communities, including Apple Valley and Burnsville. It is not yet known whether these communities keep similar records of their sanding and salting operations. 2 LAG` . Question #5: What is the chemical makeup of street sweepings and how are they disposed of? Response: Two years ago, the Dakota County Public Health Department tested the chemical makeup of street sweepings from the city to determine is those sweepings constituted a hazardous waste. The results of these tests are summarized in Attachment 2. Although nutrient analysis were not among the parameters measured, information was generated for selected toxic metals as well as chloride, specific conductivity, and ph. After reviewing the results of the test, the Dakota County Public Health Department concluded that sweepings were not a hazardous waste and therefore that required no special disposal precautions. At this time, a portion of the mixture collected through sweeping operations in the winter is reused by adding it to existing sand/salt stockpiles. Reuse of sweepings has had limited success because the fine aggregate and silts picked up with the sand causes the mixture to freeze in lumps which plugs apertures in the sanding equipment. The majority of the materials collected from street sweeping operations is disposed of at the city Maintenance Facility and used for roadbed material during construction of city parking lots, driveways, and other paved surfaces associated with city facilities. City staff are looking for information on the use of alternative materials and techniques for snow and ice control. We hope to have this information by the April Commission meeting. I will plan on discussing this information with the Commission at it's next meeting and answer questions or collect additional information as appropriate. Thanks for your interest.

To facilitate a decision an proper disposal of street sweepings, the Dakota C=ity Public Health D~* ent had samples from three (3) sources analyzed by Pace Laboratory. Samples were taken from piles of collected sweepings in Inver Grove Heights and Fagan, and a sample was taken from the streets in West St. Paul at the Intersection of Wentworth and Livingston. All sampling was done on March 3, 1990. M-Ae laboratory results indicate that contaminant levels in street sweepings are low enough to allow the use of this material as a clean fill, with some caution due to the presence of lead in the samples. The concentration of lead was below hazardous waste levels and cCxLsal levels. Barium was the only other metal detected, and the c¢ntration was not at a significant level. The chloride cx oentration was not high e=.1 i to be a major concern. The lab report is included with this memosarr3tun. The best overall option for street sweepings may be to first screen the sweepings to remove debris (pop cans, paper, bottles, etc.) The material could then be reused by blending with a new sand,/salt mixture. This is being tried at Inver Grove Heights. Other options include: use as a fill material in road beds or for land improvement projects but not in wetlands or low lards subject to flooding. The material may be suitable for use in asphalt.

A special appearance by the Easter Bunny will help make this a special day for the little ones. Registrations for this program have been "hopping" in! 4.*<< The 7th Annual Eagan Fun Run will be held on Saturday, May 2nd, at Trapp Farm Park. Race begins at 8:00 A.M. Volunteers are needed! 5.*<< Recreation Supervisors will be attending a one-day workshop on Integrated Recreation Practices on April 10, at the Earl Brown Center. University of Minnesota staff will share their experiences, perspectives and recommendations about how to meet the requirements of ADA in community recreation programming. 6. * « Two women's volleyball teams represented Eagan at the MRPA Class "C" State Volleyball Tournament on March 21 and 22nd. The "Valley Girls" team emerged as the State Champion and "The Other Side" placed fourth. 7. * < Summer program planning is underway... Staff is already receiving many phone calls on what our program offerings will be. 8.*<< As of March 24, two-hundred (200) teams are registered for the 1992 Adult Softball program. Registration ends March 27, 1992. This is below anticipated numbers. A new daytime league has only two teams registered which may cause the cancellation of that offering. A new Co-Rec Daytime League is a "go" with eight teams from Northwest Airlines. The new Friday 11/12" Co-Rec League is full, while the Co-Rec 14" Leagues are lower than expected. Room remains in the Men's and Women's Leagues. It is anticipated that the total should reach 208, which is close to the 206 teams registered in 1991. 9.*< Disciplinary action is being pursued for an incident which occurred on the last night of play in the Men's Broomball program. Two players were involved in a wrestling match. When the referee attempted to break it up, one of the players turned and punched him in the chest. Striking anyone, especially an official, is strictly prohibited. The team has not cooperated with our investigation causing Jon Oyanagi, the league director, to impose a suspension from all Eagan Leagues for the entire 47, team of the offending player. Jon is recommending to the Minnesota Recreation and Park Association that the same sanctions occur for their sport programs until the team identifies the individual involved. At that time, only the individual would be banned. MRPA reviews this issue April 2. 10.*« Men's basketball concluded March 19. A league tournament ended the season for twenty-eight teams which began last November. 11.*« The always popular Star Gazing evening will be held Monday, April 6th at 8:00 P.M., weather permitting. April 8th is the back-up date. Several members of the Minnesota Astronomical Society set up large powered telescopes at 'Thomas Lake Park to explore the spring sky. 12. * « The Walk and Bicycle Clubs are off and planning. Weekly walks will be held every Monday at 6:15 P.M. beginning April 6. Weekly bicycle rides begin Saturday, April 4 at 9:15 A.M. and Wednesday, April 8th at 6:15 P.M. All three regular events begin at the Eagan Municipal Center. Both clubs meet on the third Monday of each month to plan these and other events. Upcoming special events include the Earth Day Walk, Saturday, April 25th, and a bike ride to the Minnesota Valley Wildlife Refuge Headquarters on Sunday, April 12. 13. * « Forty (40) coaches attended the National Youth Sports Coaches Association certification clinic for the first year soccer and track coaches on Saturday, March 21. Several more clinics will be held during the next few weeks for a variety of years and sports. 14. * « Staff will attend the MRPA Annual Aquatics Conference in Mankato on April 2 & 3rd. Numerous sessions will serve as "refreshers" . . . Current American Red Cross Water Safety guidelines, staff training for aquatics, facility maintenance, concessions for pools and beaches, accessibility, programming options are but a few of the session opportunities available. 15.« Staff has been searching for a new supplier of storage boxes for athletic sites. The manufacturer used last year has gone out of business. The fiberglass boxes used last year work well. A firm in Maple Grove may be able to produce what the Department needs. 16.*« Recreation, Parks Maintenance and Parks Operations staff will conduct the following activities in the community on May 2: Fun Run, Baseball Clinic, Concessions for Eagan High School's 9th grade softball tournament and a Native Prairie event: 17.* « Eagan Athletic Association sign ups now show: In-house Baseball: 117 teams (110 projected) Travel Baseball: 10 teams (9 projected) In-house Softball: 59 teams (50 projected) Travel Softball: 4 teams (as projected) Participant numbers are approaching 2,600 youth. Field space is a very real concern, particularly for youth programs grades 6 and younger. 18.*<< Department staff have attended training on a new D-base system that will provide excellent opportunities for tracking data. Recreation staff have been in need of a system to track NYSCA Coaches certifications. The new system appears to provide the desired options to track by name, sport, year, and level of certification. Numerous additional applications will be used. 19. * << The Baby Sitting/Latch Key clinic has become so popular that additional classes will be offered in May and June. This offering is a co-sponsor activity between Parks and Recreation and the Women's Fire Auxiliary. 20.*,< Eagan High and Dakota Hills Middle School Co-Curricular baseball, softball and tennis activities will again use Northview Athletic and Goat Hill facilities, in addition to those located on the school complex. Practices are underway now. The first games will be played on April 8. 21.*<< Staff recently met with a representative from the Mosquito Control District to identify heavily used parks and program time frames to assist that organization with its plans for mosquito control this summer. 22.*<< The City of Savage will direct the South of the River Power Sand Volleyball League this summer. Match play will begin in June. 23. * << The Ultra Slim-Fast Co-Recreational tennis league will again be organized with the City of Inver Grove Heights. Eagan offers this league to our South of the River neighbors, and teams from Apple Valley, Lakeville and Burnsville have played in previous years. 24.*« Two new sets of soccer goals were constructed during the month of March. These sets will be used at Downing and Wescott Station Parks this season. 25.*<< Work continued on the fabrication of nine new sets of hockey goals. It is expected that this project will be completed by the end of March. 26. * « Two improvements were made to the Rahn activity building on Sandstone Drive. Scott Eppen and Gary Skogstad teamed up to install a new acoustical ceiling in the auxiliary room of the building, and also built a new storage cabinet for the Tiny Tots and Summer Recreation Programs, which originate out of this building. 27. * << During the week of March 23, 1992, warmer temperatures arrived and tennis nets were put up on all 34 of the City's tennis courts. Use has already been heavy in some sites, particularly the Northview Tennis Courts, which are being used by the High School's tennis teams. 28.* << Sweeping of the City's sixty plus miles of boulevard trails was conducted during the month of March. Due to the heavy snows in early winter, an unusually large amount of sand and salt was used on the City streets and in particular, the County Highways. This left a considerable mess on the boulevard areas, and in some cases required mechanical sweeping of the grass areas to minimize damage to the turf. 29.*< Park Maintenance worker Steve Taylor is credited with designing a new shroud for the front of the new Groundsmaster sweepers, in order to prevent sand and other debris from flying into the roadway. 30. * « Operational supplies were removed from the Trapp Farm sledding hill in late March. This included removal of the temporary fence, storage facility, inner tubes, decorative lights, etc. 31.*<< Operation of the lake aeration system at Fish Lake continued through the month of March. Colder temperatures and snow earlier in the month prompted the D.N.R. to request that the system continue in operation. 32.*<, Several training opportunities were afforded to the parks maintenance staff during the month of March. On March 19, Dan Curtin, Steve Taylor and Don Buecksler attended an operation maintenance school for the Toro 580-D high capacity rotary mower; on March 11 and 12th, Scott Eppen, Gary Skogstad and Rich Pelletier attended an irrigation and maintenance school sponsored by MTI Distributing. Tom Schuster participated in the Annual Tree Inspectors Tree Certification workshops sponsored by the Minnesota Department of Agriculture on March 25 & 26th. Jim McGuffee and John VonDeLinde attended the Annual Loss , Control Workshop sponsored by the League of Minnesota Cities at the Earle Brown Center, University of Minnesota on March 25th. In addition to these seminars, Park Supervisor, Jim McGuffee, also developed and presented an in-house training session on chemical pesticide application for the Department's full time personnel. 33. * << On Saturday, March 28, City Forester Tom Schuster, and John VonDeLinde received the City's 5th Annual Tree City Award and National Arbor Day Foundation Growth Award at the University of Minnesota. This program is jointly sponsored by Minnesota Department of Natural Resources and Department of Agriculture. 34. * << In early March, our City Forester, Tom Schuster, met with all the third grade community elementary classes to initiate the 1992 Poster Drawing Contest. More than 800 students will be involved in the poster contest and a tree conservation program. 35.* << The Director of Parks and Recreation, Ken Vraa, conducted an informational presentation for an "all employee" meeting to explain the Pool/Arena Project on Thursday, March 26th. *City Council - April 7, 1992 *Commission Meeting - April 2, 1992 MEMORANDUM TO: KEN VRAA, DIRECTOR OF PARKS AND RECREATION yin FROM: JON OYANAGI, RECREATION SUPERVISOR DATE: MARCH 25, 1992 RE: WINTER RECREATION SITES REPORT The 1991/92 winter recreation sites officially closed for the season February 17, 1992. Trapp Farm Park was in operation one additional week-end. The weather was very mild throughout the season and conditions were less than ideal for maintaining ice. Due to the early snowfall, however, the tubing hill opened three week-ends early and stayed open one extra week-end. After opening day at the skating sites, December 20, daily high temperatures exceeded 32 degrees for two weeks straight. A short cold spell followed, but quickly reverted to above normal temperatures which eventually led to a drastic deterioration of the skating rinks. Most schools had two weeks off around the holidays which, along with the mild temperatures, brought out skaters and tubers in mass. All twelve sites were extremely busy. People of all ages could enjoy the winter activities without the bitter cold. Therefore, more people were out and they stayed for a longer time. The staff did a better job of helping park users enjoy the winter through increased interaction, leading activities, enforcing rules and keeping a presentable warming shelter. Four college graduates, thirteen college students, four high school graduates and nine high school students made up the staff team. This was, overall, a very mature staff. Attached is an attendance report for eleven of the twelve sites. Leaders were to take a census at four times throughout the day. As you can see this was not consistently done, but a picture is created. The first four columns show the average attendance at that site at the time indicated. The last column shows the average daily attendance by adding all attendance numbers and dividing by the total number of days that were surveyed. This is purely a relative number for comparing sites rather than indicating attendance. It does not account for weekdays when counts are done only at 5:00 and 7:30 or that the 12:30 and 2:30 counts are only done on weekends and holidays. Clearwater, where no reports were turned in, is a very popular site whose numbers increased as people became aware that it was re-opened after a year out of service. Attendance is usually high, with 50 to 100 people skating during the busiest periods. The warming shelter is too small for the large crowds. WINTER RECREATION REPORT PAGE TWO MARCH 25, 1992 The drive-by surveys done at the Class D sites indicated regular use at Highview and Slater Acres, little use at Country Home and Evergreen and no rinks at Bur Oaks and Cedar Pond due to the risky conditions on the ponds. Evergreen is little used possibly due to the re- opening of Clearwater Park. I would recommend not maintaining Cedar Pond, Evergreen, Country Home or Bur Oaks Pond next season keeping in mind the constant need to assess the demand from neighborhood feedback and to look at the eastern portion of Eagan for alternate sites. That area is growing and we have fewer sites east of Lexington Avenue. Woodhaven and Lexington rinks have older, shack-type warming shelters in poor condition. I would recommend the replacement of those buildings with ones similar to Clearwater Park or a rented trailer. Pilot Knob Park saw low usage again this year. I would recommend putting those lights on a timer and eliminating the warming trailer. This frees up the trailer we own for either Lexington or Woodhaven. Phones should be made available at all staffed sites for emergency purposes. Currently, Lexington, Woodhaven, Pilot Knob and Ridgecliff are without phones. I feel strongly that phones are necessary for emergency medical and mechanical reasons. This year Cardiopulmonary Resuscitation training was provided by the Eagan Fire Department. This was a valuable benefit to offer the leaders. Next year I would like to offer basic first aid which is a more practical tool on a day-to-day basis. The hot chocolate sales were expanded from four sites in 1990-91 to seven this season. Expenses totaled $1,624.02 while revenues totaled $1,976.79. The cost of supplies increased slightly due to the use of paper cups versus Styrofoam. The price we charged increased from $.25 to $.50 this year. A surplus of chocolate and cups are on hand to start next season. Pop was requested form several sites, in part due to the warm winter. Skaters and tubers were warm, instead of cold, for the majority of the season. This fall the Parks and Recreation Department will have to evaluate the sites available to determine efficient use of resources while meeting he needs of the community. Factors impacting decisions include the 1993 budget, the development of a tubing hill at Blackhawk Park, the ice arena proposal and the ever-changing demographics within Eagan.

SUBJECT: COMPREHENSIVE GUIDE PLAN AMENDMENT, REZONING, AND PRELIMINARY PLAT (GREAT OAKS) APPLICANT: ROBERT ENGSTROM COMPANIES LOCATION: E 1/2 OF SECTION 14 EXISTING ZONING: PLANNED DEVELOPMENT - MULTIPLE FAMILY (PD - R-4) DATE OF PUBLIC HEARING: MARCH 24, 1M DATE OF REPORT: MARCH 17, 1992 COMPILED BY: COMMUNITY DEVELOPMENT DEPARTMENT APPLICATION SUMMARY: Separate applications have been submitted requesting a Comprehensive Guide Plan Amendment from D-3 (Mixed Residential, 6-12 units/acre) to D-1 (Single Family Residential, 0-3 units/acre), a Rezoning of 17 acres from PD R-4 to R-1 (Single Family Residential), and a Preliminary Plat consisting of 29 single family lots and two Outlots. This Rezoning will remove the subject parcel from The Woodlands North Planned Development. The site is located west of Elrene Road approximately one-fourth mile south of Yankee Doodle Road and north of The Woodlands subdivision. BACKGROUND: The site is part of The Woodlands North Planned Development that was created in June 1990 allowing for Mixed Residential uses including 12 single family lots, 62 duplex-type buildings, and 200 multiple residential units on approximately 58 acres. In September 1990, the PD was revised to allow for 10 additional duplex units in an effort to offset financial obligations to the City. EXISTING CONDITIONS: The site includes Lot 2, Block 4, part of Lot 2, Block 1, Wescott Garden Lots, and Outlot D of The Woodlands North Addition, and lies south of the existing and future Woodlands North duplex townhomes; Elrene Road is to the east, The Woodlands Addition is to the south, and agricultural land to the west. The site has slopes ranging from moderate to severe and there are several natural ponding areas on site. The site varies from some cultivated areas to significant mature primary tree growth on the majority of the site. The applicant has accommodated as much tree preservation as possible with a lot layout that is sensitive to the site's natural amenities. Due to severe grades, the developer should provide the City a concept showing house pads and grading for Lots 6 and 7, Block 1, and the cul-de-sac serving those lots. COMMENTS: A single internal street is proposed that will gain access to the site from Elrene Road and run along the north side of the site before it turns south on the west side of the plat and ends in a cul-de-sac. There will be no lots to the north of this road. Two other cul-de-sacs also stem off this internal road. The R-1 zoning district requires an 85-foot minimum lot width at setback and a minimum lot size of 12,000 sq. ft. The lots proposed range in size from 13,784 sq. ft. to 67,216 sq. ft. The median lot size is 40,500 sq. ft. All but four lots meet, or exceed lot width requirements. The plat includes four lots with a stovepipe configuration. These stovepipe lots have a width of 20' at the street. City Code requires a minimum width of 50' for this type of lot and therefore, the applicant is requesting a Variance from this performance standard for Lots 20, 21, 28, and 29, Block 1. The applicant has proposed two Outlots with this plat. Outlot A is residual property laying between the internal street and the north property line. Outlot B will be developed in conjunction with the adjacent 1.3 acre piece of undeveloped Multiple Family (R-4) property that lies between the proposed plat and the R-2 zoned property of The Woodlands North along Elrene Road. Outlot A should become part of the existing and second phase R-2 lots north of the plat when Phase II is platted. The developer expects homes valued at a minimum of $240,000 in this subdivision. The developer plans to include building restrictions where applicable as a part of the purchase agreement for lots that require special attention in order to maintain the integrity of the site. Tree preservation should be achieved with a physical barrier. Protection of trees to be saved during site grading shall be enclosed with snow fencing or other suitable material. Also, boulevard trees will be allowed 7' from the back of the curb. PARKS, RECREATION, AND NATURAL RESOURCES: Parks, Recreation, and Natural Resources staff will be recommending a cash parkland dedication and a cash trailway dedication to the Advisory Parks, Recreation, and Natural Resources Commission at its April 2, 1992 meeting. AIRPORT CONSIDERATION: This proposal does not fall within the Metropolitan Council's noise policy contours, but it is close enough-1/4 to 1/2 mile-to address the issue. Since aircraft currently fly further south than when the contours were developed, noise may be considered to be intrusive by some of the project's residents. Therefore, while we cannot require the developer to meet Metropolitan Council standards, it would be appropriate to share with him ways to abate the noise within the units by considering incorporation of such elements as chimney caps, elbows, vents, and similar features of sound environments of the units may be substantially improved without considerable cost to the project. GRADING/DRAINAGE,IEROSION CONTROL: The proposed development consists of approximately 20 acres of rolling hills. Some portions of the site are wooded and other portions have been cultivated in the past. The preliminary grading plan shows many areas that will be filled to construct the proposed streets and house pads. The maximum fill shown is 16 feet and the maximum cut is 8 feet. The preliminary grading plan intends to protect the existing trees on this site and to utilize the high spots for house pads. The low areas on the site will be used for ponding areas. Drainage from the proposed streets will be directed to two low areas which will be converted to ponding areas and included in the City's public storm water system. Pond JP-14.2, which will located in the east central portion of this site, shall provide 0.2 acre-feet of pond storage volume to allow a maximum discharge rate of 1 cfs. The drainage area that will contribute to Pond JP-14.1, which will be located in the center of this site, will require a pond storage volume of 1.9 acre-feet to allow for a maximum discharge rate of 3 cfs. The 12 inch outlet pipe for Pond JP-14.2 shall be constructed to drain into Pond JP-14.1. The 12 inch pond outlet pipe that will drain Pond JP-14.1 shall be constructed to the normal water level of Pond JP-14. The alignment of this storm sewer pipe shall avoid the oak trees in this area. The normal water level of Pond JP-14.1 should be set to protect the existing trees along the east edge of the pond. The preliminary grading plan needs to be revised in the northwest corner of this site to allow for the construction of Pond EP-2.3. Pond EP-2.3 is designed to handle the runoff from the duplex area of the Woodlands North development. The pond shall be sized to handle a wet storage volume of 2.0 acre-feet and a pond storage volume of 3.2 acre-feet. The development will be responsible for installing and maintaining erosion control measures in accordance with the City's Erosion/Sediment Control Manual Standards. WATER QUALITY: This 17-acre single-family residential development lies in the upper reach of Drainage Basin J. While there are no recreational classed water bodies immediately down-drainage, Fish Lake lies at the lower end of this drainage. Fish Lake does not meet the Direct Contact Recreation water quality standards set for it in the City's Water Quality Management Plan. On-site ponding to meet water quality standards is both desirable and feasible for this site. Analysis using the City's water quality model indicates that the developer will be able to use two natural depressions on the site to create ponds that will meet treatment standards. The larger of the two depressions, Pond JP-14.1, lies in the west central portion of the site and will be shaped to provide a minimum surface acreage of 0.3 acres and a minimum wet pond volume of 0.8 acre-feet. The other depression, Pond JP-14.2, lies in the east central portion of the site and will be modified to provide a minimum surface area of 0.13 acres and a minimum wet pond volume of 0.31 acre-feet. Both ponds shall be constructed according to NURP standards and the pond design as approved by the City. This recommendation is subject to approval by the Advisory Parks, Recreation and Natural Resources Commission. ~7. UTILITIES: Sanitary sewer of sufficient depth and capacity is readily available to serve this development in Elrene Road. The preliminary utility plan shows an 8 inch sanitary sewer line that will extend through the development to serve the 30 lots of this site with the exception of Lot 24. Sanitary sewer service is not shown to be provided to Lot 24 which is located in the southwest comer of the development. Lot 24 shall be platted as an outlot until sanitary sewer and water service and improved street access is provided to the lot. Water main of sufficient pressure and capacity is readily available along Elrene Road. The preliminary utility plan shows connecting to the existing 16 inch water main along Elrene Road and extending the water main through this site to serve the proposed lots. The City's Water Distribution Plan shows a 16 inch water main that is required to be extended through this plat from Elrene Road to the west property line. The 16 inch water main will be a trunk water main and the developer could have this water main constructed through the City's public improvement process. City staff recommends that the water main on the west end of the development shall be connected to either the existing 8 inch water main in Woodland Trail to the south or the existing 8 inch water main in Trails End Road to the north. Either of these connections will provide adequate looping and fire protection to serve this site. The utility plan shall be revised to include sanitary sewer and water services to Outlot B and the exception to the Woodlands North Addition that is owned by the Obergs along the north edge of Great Oaks Trail. The services will serve the future lots that may be developed along the north side of Great Oaks Trail. According to the preliminary utility plan, the sanitary sewer in Great Oaks Trail in front of Lots 15 and 16 will be approximately 30 feet deep. The 8 inch sanitary sewer and service risers in this area shall be constructed with DIP materials for any depths that will be greater than 26 feet deep. STREETS/ACCESS/CIRCULATION: Street access for the proposed development will connect to Elrene Road which was upgraded to an urban section with concrete curb and gutter by the City in 1991. The final lift of bituminous wear has not been placed yet on Elrene Road. The preliminary street plan shows construction of a 1,600 foot long cul-de-sac with two other cul-de-sacs branching off of this street. The street plan does not show any connections to Trails End Road along the west edge of the plat. Access for Lot 1 is shown to be provided off Elrene Road and access for Lot 24 is shown to be provided off Trails End Road. Platting of this development will require the upgrading of Trails End Road to an urban section with concrete curb and gutter. If the alignment of Trails End Road changes as the areas to the west of this development develops, then Trails End Road would not need to be upgraded with this development. Then the old right-of-way of Trails End Road would be vacated and included into the lots of this development. The preliminary street plan shows an entrance island at the intersection of Elrene Road and' the proposed street of Great Oaks Trail. Also, islands are shown in the cul-de-sacs of this development. The developer also plans to construct an island along the north edge of Lot 12 to allow for motorists to turn around and to break up the straight alignment of Great Oaks Trail. All of the islands shall be constructed and designed to the City's standards as shown on the City's detail plates. A concrete valley gutter shall be constructed across the -1. intersection of Elrene Road and Great Oaks Trail. The preliminary plat and preliminary street plan shows that Great Oaks Court, the cul-de-sac in the northwest corner of this site, will be constructed with dimensions smaller than the City's standards. City staff will recommend that the preliminary plat and preliminary street plan be revised at the northwest corner of the site to allow the design of the lots and the street to meet the City's standards. If the design of Great Oaks Court cannot be designed to City standards, then access to Lots 28 and 29 could be provided off Trails End Road. EASEMENTS/RIGHT-OF-WAY/PERMITS: This development shall dedicate all right-of-way and easements necessary for the construction of the streets and utilities to serve this development. According to City standards, the right-of-way for cul-de-sacs with islands shall have a radius of 65 feet. If the cul-de-sac does not have an island, then the radius shall be 55 feet. The storm sewer pipe that will serve as the outlet for Pond JP-14.1 will require an easement from the owner of Lot 3, Block 4, of Wescott Garden Lots depending on the alignment of the storm sewer pipe. Lots 29 and 30 in the northwest corner of the site should include the entire area of Pond EP-2.3. The redesigned lot lines of 29 and 30 would extend to the north up to the preliminary plat of future Lot 40 of the duplex portion of the Woodlands North. This development shall be responsible for ensuring that all regulatory agency permits (MPCA, MWCC, Mn. Dept. of Health, etc.) are acquired prior to final plat approval. FINANCIAL OBLIGATION - Great Oaks Addition Based upon the study of the financial obligations collected in the past and the uses proposed for the property, the following charges are proposed. The charges are computed using the City's existing fee schedule and connections proposed to be made to the City's utility system based on the submitted plans.
