The regular Commission meeting will begin promptly at 7:30 p.m. at the Municipal Center. Once again, the agenda for the Advisory Commission is relatively light for this meeting. There are three items under the Consent Agenda. If members of the Commission have a concern about one of the Consent items, that item can be withdrawn from the Consent Agenda for review. If not, a single motion to approve all three items would be appropriate. There is one item under Development Proposals, which is the Wenzel Addition. The Advisory Planning Commission heard this item at its August 25th meeting. The item was withdrawn prior to Commission's vote. However, Parks and Recreation staff are recommending that the Advisory Commission review this proposal and make a recommendation to the City Council regarding Parks Dedication and Trail Dedication requirements. There is one item under old business, which is a report on the Oak Wilt disease problem as it affects Eagan. The staff has prepared extensive background information pertaining to Oak Wilt disease and will supplement it with verbal comments at the Commission meeting. Under New Business, staff has prepared summer recreation reports which outlines some of the summer activities the department has been involved in. Staff would be happy to review these with you and respond to questions by the Advisory Commission. If it should appear that there is extensive questions or concerns, or suggestions for improvements for next year, it might be advisable to refer those comments to the next recreation subcommittee meeting for further intensive review and recommendation. Under Parks Development, staff will update the Advisory Commission on the progress of Blackhawk Park. Bids have been opened for the construction of the park and are scheduled for the September 1, 1992, Council meeting for award. Steve Sullivan, Landscape Architect/Parks Planner, will also update the Advisory Commission on Captain Dodd Park and the status of a number of fall projects scheduled this year. Under Water Quality, Water Quality Coordinator, Rich Brasch will view an executive summary of the lower Minnesota River Non-Point Source strategy and the status of this item. Staff would also like to set a meeting date for a Wetlands Task Force meeting . Under Other Business and Reports, staff would like to review for you the departmental Happenings, a copy of which is enclosed for your reviewal. As always, if members are either unable to make the tour or the regular meeting, notification to the department staff would be appreciated.

CONSENT AGENDA After review of the park and trail dedication issues by Park Planner Stephen Sullivan and review of the water quality issues by Water Resources Coordinator Rich Brasch, Kevin Knight moved, Jonathan Widem seconded the motion to make the following recommendations to the City Council. All members voted in favor. 1. Bur Oak Hills 3rd Addition - Shamrock Development. This plat is to be subject to a cash parks dedication and a cash trails dedication. This plat will also be subject to a cash dedication, estimated at $522, to meet water quality requirements. 2. Wilson Addition - Mary Ann Wilson. Lots 2, 3 and 4 will be subject to a cash parks dedication and cash trails dedication. The development shall be subject to a cash water quality dedication, estimated at $1,036, to meet water quality requirements. 3. St. Thomas Becket Addition - St. Thomas Becket Church. This plat is subject to a cash trails dedication. This parcel would be subject to a cash parks dedication with any future change in zoning worth than Public Facilities. The development would be subject to a ponding requirement to treat all run-off from impervious areas prior to discharge of site. The ponding configuration must be approved by staff. The wetland fringe along Hay Lake must be delineated according to Wetlands Conservation Act criteria and avoided during construction and post-construction activities. The developer's replacement plan for filling of a portion of the small wetland in the southeast portion of the construction site should be approved if it meets or exceeds the acre-for-acre replacement criteria under the Wetlands Conservation Act. Advisory Parks, Recreation and Natural Resources Commission Minutes of Regular Meeting of August 6, 1992 Page 2 AMERICANS WITH DISABD.ITIES ACT (ADA) UPDATE ON THE CITY'S TRANSITION PLAN Recreation Superintendent Peterson introduced this item as a follow-up to the Commission on the work that City staff has accomplished since this legislation took effect on January 26, 1992. Staffs efforts since January have been directed toward the first compliance requirement. By July 26, 1992 the City must provide a transition plan which 1) evaluates the accessibility of all City facilities; 2) identifies structural barriers to accessibility; and 3) outlines what structural changes can reasonably be made. By January 26, 1993 all barriers to program accessibility must be identified and a plan to remove barriers to participation in City programs must be in place. Superintendent Peterson continued that the Department is fortunate in that most of the park facilities have been constructed since 1984 and meet the accessibility standards that were required at that time. Steve Sullivan explained that many of the existing facilities have been constructed using federal funds which required strict accessibility standards. Superintendent Peterson noted that the Department has been cognizant of the need to provide accessibility within the park system and had done a fine job in ensuring that was provided during the planning stages. Staff and a volunteer who uses a wheelchair spent time testing the accessibility of various park sites. Trapp Farm Park had some minor barriers which included the drinking fountain adjacent to the pavilion which could not be routinely accessed by wheelchair along with the concrete approach to the exterior door to the women's restroom that can be difficult to access by wheelchair. Access from the shelter, however, is readily available. The shelter building with the most significant barriers (Rahn shelter building) was built in 1976 and the City's self assessment, conducted in 1984, rated the entrance to this building as 57% accessible and the interior as 71% accessible. The restrooms are not wheelchair accessible at all. Dorothy indicated that although there are some accessibility issues, the park facilities, as a whole, provide accessibility. The second phase of the ADA study, Dorothy continued, will assess accessibility program by program. This would mean that each recreation program would need to be accessed. The feasibility of auxiliary aids, the directive that modifications that fundamentally alter the nature of a program are not required and the ability to offer an alternate site will enable staff to provide a comprehensive plan by January of 1993. Superintendent Peterson concluded that there is no action required by the Commission on this issue but staff wanted to keep them updated on any items that will impact the Department within the time frames the ADA legislature has mandated. She noted that according to the ADA time line structural changes identified in the transition plan are required to be completed by January of 1995. This, along with providing auxiliary aids for recreation programs may have a significant impact on the budget. Commission Member Billy thanked staff for their comprehensive report and also for keeping the Commission abreast of new development regarding ADA legislation. UPDATE ON BLACKHAWK PARK Park Planner/Landscape Architect Sullivan noted that the plans and specifications are being prepared in anticipation that they will be distributed to bidders on or about August 10 with bids due on August 21, 1992. Steve continued that he will update the Commission at the September meeting on the status of this contract. Advisory Parks, Recreation and Natural Resources Commission Minutes of Regular Meeting of August 6, 1992 Page 3 DEPARTMENT HAPPENINGS Dorothy Peterson recapped the success of the summer programs that have recently concluded and noted that staff is almost ready to begin the planning for fall activities. Parks Superintendent VonDeLinde highlighted the completion of Trapp Farm Park playground recognizing the leadership of Steve Hadden and Paul Szurek and the help by the Twin Cities Tree Trust Organization on this project. John also recognized Alex Lammers and Don Buecksler for their excellent work in completing the new playground at Wescott Station Park. Again, the Twin Cities Tree Trust assisted in the completion of this project. An additional item that Mr. VonDeLinde presented was that the City will receive an America the Beautiful Grant for the completion of the Forestry brochure series. John indicated that staff hopes to have a draft of the brochures for the Commission in September with the final product hopefully completed by October. Ted Billy commented that on the Commission's pre-meeting tour of parks he noted how well maintained all the facilities are but specifically wanted to recognize the excellent job staff has done at Sky Hill Park. With no further business to conduct, Kevin Knight moved, Dan Mooradian seconded with all members voting in favor to adjourn the meeting. The meeting was adjourned at 7:50 p.m. Secretary Date MEMORANDUM TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: STEPHEN SULLIVAN, LANDSCAPE ARCHITECT/PARKS PLANNER DATE: AUGUST 20, 1992 RE: CONSENT AGENDA - SEPTEMBER 3, 1992 1. DEERHAWK ADDITION - DAKOTA COUNTY STATE BANK A Preliminary Plat consisting of approximately 2.42 acres containing five single- family lots located in the SE 1/4 of Section 20 on Deerwood and Taconite. RECOMMENDATIONS: A. The proposal be subject to a cash parks dedication. B. The proposal be subject to a cash trails dedication. 2. WHISPERING WOODS 9TH ADDITION - HILLA, INC. A Preliminary Plat consisting of approximately 5.2 acres containing 11 single-family lots plus one outlot, and Rezoning from Agricultural to Single Family located in the SW 1/4 Section 31. RECOMMENDATIONS: A. The proposal be subject to a cash parks dedication. B. The proposal be subject to a cash trails dedication. C. The developer provide a tree protection plan for city review and approval. 3. OAK CLIFF 7TH ADDITION - BRIAN S. MANGINE A Preliminary Plat consisting of approximately two acres with one lot for a deli/hall, and a Planned Development Amendment amending the use from retail to deli (Class II restaurant)/hall located in the NW 1/4 of Section 31. RECOMMENDATIONS A. The proposal be subject to a cash parks dedication. B. The proposal be subject to a cash trails dedication. MEMO TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: RICH BRASCH, WATER RESOURCES COORDINATOR DATE: AUGUST 25, 1992 SUBJECT: WATER QUALITY AND WETLAND PROTECTION REQUIREMENTS FOR DEERHAWK ADDITION - DAKOTA COUNTY STATE BANK (CONSENT AGENDA ITEM) PROPOSAL This preliminary plat application is for a single family residential development consisting of five lots on 2.4 acres located along the south side of Deerwood Drive in the southeast 1/4 of Section 20 (Figure 1). FOR COMMISSION REVIEW The Commission will need to review and make a recommendation regarding whether the development should be subject to a ponding requirement and/or a cash dedication requirement to meet water quality standards as set by the city and it's Water Quality Management Plan. There are also wetlands issues associated with this plat. WATER QUALITY ANALYSIS This parcel lies in drainage basin A, on the southeast corner of Blackhawk and Deerwood Roads. Runoff from impervious areas of Lots 1 and 2 will drain to Blackhawk Road while runoff from impervious areas on Lots 3 through 5 will drain to Deerwood Road. In either case, runoff from these areas will discharge via the city storm sewer system to Pond AP-2, a low area designated as a Class VII storm water basin in the City water quality management plan. AP-2 then discharges to AP-1 in Woodhaven Park, a Class III Scenic Recreation waterbody. Analysis using the city's water quality model shows that runoff from the site will have a negligible impact on this recreational waterbody. Because of the small size of this development, it's location in an area that is of relatively low priority for water quality management purposes, and a projected lack of impact on the nearest downstream recreational waterbody, a cash dedication in lieu of treatment would be acceptable for this site. The cash dedication is estimated at approximately $1,900. PAGE 2. AUGUST 25, 1992 WETLANDS IMPACTS One wetland has been located on the northwest portion of the site and lies in the northern half of Lots 2 and 3 (Figure 2). The wetland has been identified as a combination Type 2 (Inland Fresh Meadow), and Type 6 (Shrub Swamp), and is approximately 8,000 square feet in surface area and isolated from other waterbodies. The developer proposes to fill about 1,500 square feet of the eastern portion of this wetland to create a house pad on Lot 3 and replace this area by expanding the wetland to the west. If filling of the wetland is avoided altogether and the lot is still used as a homesite, the only other option is to move the house pad toward the rear of the lot. This location would require destruction of a significant number of mature oak trees. The developer maintains that foregoing any construction on Lot 3 to avoid wetland impacts makes the entire development economically unfeasible. STAFF RECOMMENDATION Staff recommends that the developer be required to provide a cash dedication in lieu of ponding on site to meet water quality treatment requirements. Staff also recommends that the developer be allowed to fill not more than 1,500 square feet of the wetland that currently lies on site and that this filled area be replaced on site at a ratio not less than one surface acre replacement to one surface acre filled as required under the Interim Program of the Wetlands Conservation Act.

PROPOSAL This preliminary plat application is for a single family residential development consisting of eleven lots on 5.2 acres currently zones for agricultural uses. A rezoning to single family residential has also been requested. The location of the development is in the southwest 1/4 of Section 31, south and west of the intersection of Slater Road and Storland Road. FOR COMMISSION ACTION The Commission will 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 water quality standards as set by the City in it's Water Quality Management Plan. There are also wetland issues associated with this plat. WATER DUALITY ANALYSIS This proposed development is located in the far southwest corner of the City of Eagan and actually lies outside any of the designated drainages for the City. Runoff from this development will discharge to a storm water pond designated E-24 and located in the City of Burnsville. Pond E-24 is approximately 9.5 acres in surface area and contains an outlet on the west end that drains the pond through Burnsville to the Minnesota River. Because the proposed development drains water to the City of Burnsville, there was some question regarding how to apply the water quality mitigation standards required by the City of Eagan. After discussing the issue at some length in-house, staff drafted a policy recommendation and justification that was forwarded to the developer. A copy of this letter is attached. The letter recommends requiring a cash dedication from the developer to meet water quality requirements for this proposed development. The Commission is encouraged to review this letter and to decide whether or not to approve the recommended policy. WETLANDS ISSUES A full inventory of the wetlands within the boundaries of this development has not been //5 PAGE 2. AUGUST 26, 1992 conducted. Field review of the development by City staff indicated that there were two wetland areas that could affect development on the site. The first is a combination Type 3 (Inland Shallow Fresh Marsh) and Type 1 (Seasonally Flooded Basin) whose cumulative surface acreage is approximately.4 acres (Figure 2). This wetland is located mostly east of the eastern border of the proposed development and is isolated from other waterbodies. About 1,600 square feet of the Type 1 wetland would be filled due to the construction of a proposed southward extension of Slater Road associated with the development. The developer contends that this wetland is not a natural wetland, but has formed because of construction of Storland and Slater Roads which block the drainage to the north. If correct, draining or filling of this wetland would be exempt from regulation under the Wetland Conservation Act. On August 18, 1992 the developer submitted an official request for exemption for filling of this wetland under the Wetlands Conservation Act. The request was reviewed by a technical evaluation committee composed of the City of Eagan's Water Resources Coordinator, a representative of the Board of Soil and Water Resources, and a representative of the Dakota County Soil and Water Conservation District. The committee reviewed the developers information and visited the site on August 24, 1992. Based on the location of dead vegetation characteristic of upland conditions, the elevation of high water marks on that vegetation, and the elevation of that area of the wetland on which encroachment would occur, the committee voted unanimously that the wetland did appear to have been enlarged if not created as a result of road construction, and that the encroachment on the wetland associated with the Whispering Woods development should be exempt from regulation under the Wetlands Conservation Act. The second wetland on-site is a fringe wetland along the City of Burnsville Pond E-24. This wetland has not been delineated. Because of the high potential for erosion in this more steeply-sloped area, this wetland should be delineated prior to the preliminary plat approval and completely avoided during grading and construction of the development with respect to filling, burning, or draining in order to protect Pond E-24. STAFF RECOMMENDATION This development should be subject to a cash dedication requirement to meet water quality standards. In addition, the fringe wetland around the City of Burnsville's Pond E-24 must be delineated prior to preliminary plat approval and filling, burning, or draining of the wetland is prohibited. /(n .

I have since gathered some information that I think will shed some light on the issues that arose during our discussion. The basis for the city water quality dedication policy is that is provides a means of protecting or improving Eagan's priority waterbodies which provide benefits for all Eagan residents in a way similar to the city park system. In fact, the city's water quality dedication and park dedication policy are structured and administered in a similar manner. In addition, the water quality ordinance is a city-wide ordinance that applies to all developments located within the jurisdictional limits of the City of Eagan. I also discussed with Tom Colbert the example you brought up regarding Eagan's assessment of property in Inver Grove Heights to address drainage volume issues. This situation can occur under current inter-city agreements but only with regard to storm trunk assessments, not with regard to water quality fees. Given this background, I will be recommending that a cash water quality dedication be required for the Whispering Woods 9th Addition. The cash from this dedication will be used to help finance water quality improvements in Eagan that provide public benefit to the community consistent with the adopted city policy. I've estimated the cash dedication for Whispering Woods 9th Addition at approximately $4,100. THE LONE OAK TREE THE SYMBOL OF STRENGTH AND GROWTH IN OUR COMMUNITY Equal Opportunity/ Affirmative Action Employer SCOTT HILLA AUGUST 7, 1992 PAGE 2. If you feel you would like to request a variance from this requirement, your forum for doing so is the September 3rd meeting of the Parks, Recreation and Natural Resources Commission. The Commission will review the water quality, wetlands, and parks/trails aspects of your development and pass their recommendations along to the City Council for the Council's use in deciding whether to approve the preliminary plat. Please contact me at (612) 681-4300, TDD phone: (612) 454-8535 if you have any questions on this issue or the wetlands issue we discussed at the Monday meeting.

MANGINE (CONSENT AGENDA ITEM) PROPOSAL This preliminary plat application is for a neighborhood business and consists of one lot on approximately two acres. The proposed development is actually included within the area covered by the Oak Cliff 6th Addition located south of Cliff Road and west of Slater Road in the northwest 1/4 of Section 31 (Figure 1). FOR COMMISSION REVIEW There are neither new water quality nor wetland impact issues associated with this proposed development. Water quality treatment requirements for this proposed plat have been met through construction of an off-site treatment pond as part of the Oak Cliff 6th Addition. In addition, no wetlands subject to Wetlands Conservation Act jurisdiction lie on the site. STAFF RECOMMENDATION No additional action on water quality or wetland protection issues is required for this site.

BACKGROUND The parcel is located south of Deerwood Middle/Elementary School and north of County Road #30. The Commission had reviewed this parcel as a component of a Park Service Area #21 study. The proposal at the time was whether the City should acquire property for a school/park with the improvement of the middle school. The school/park scenario was not pursued. The Commission felt that the future land use of the 80 acre undeveloped property west of the Wenzel property would determine the park land needs for P.S.A. #21. ITEMS FOR COMMISSION REVIEW The Commission will need to review and make recommendations regarding the following items: 1. What is the Parks Dedication obligation? 2. What is the Trails Dedication obligation? 3. What is impact to the woodland resource? 4. What is the Recreational Open Space obligation? ITEM #1 - PARKS DEDICATION The parcel is within Parks Service Area #21. As mentioned within the background an evaluation of the park needs will be completed with the zoning and platting of the 80 acre parcel located west of the Wenzel property. Therefore, staff recommends to the Commission that this plat be subject to a cash Parks Dedication. ITEM #2 - TRAILS DEDICATION An 8' bituminous trail exists adjacent to the subject parcel on the north side of County Road #30. An assessment review concludes that the Wenzel property has not provided towards the cost of this trail. Therefore, staff recommends to the Commission that this plat be subject to a cash Trails Dedication. Deerwood Elementary/Middle School lies to the north of the parcel. The proposal indicates a 25' trail easement within the northeast corner of the plat providing pedestrian linkage between the 2 adjacent parcels. Staff has reviewed this trail alignment with School District personnel. The School District approves this alignment and will provide a concrete sidewalk to this trail easement. The developer needs to coordinate with the School District compatible grading, alignment and scheduling of work. The developer shall be responsible in providing an 8' wide trail pad at finish grade. The City of Eagan will be responsible for the installation of the concrete sidewalk. ITEM #3 - WOODLAND RESOURCE A majority of the site is in cash crop. A woodlands mass encompasses Pond BP-4. The vegetation type is primarily willow, boxelder and poplar. Scattered white oaks exist northwest of the pond. A portion of these white oaks are proposed to be removed with development. A majority of the existing vegetation will remain. Staff concludes that the impact to the woodland resource is minimal. ITEM #4 - RECREATIONAL OPEN SPACE Chapter 11 of the City Code provides for Recreation Open Space within all multiple family developments. The code reads as follows: 12. Each multiple dwelling complex shall have a minimum recreation area equal to two hundred (200) square feet for each dwelling unit containing two (2) or less bedrooms and one hundred (100) additional square feet for each dwelling unit containing more than two (2) bedrooms. Said recreation area shall be a minimum of one hundred (100) feet from any ponding area. Source: Ordinance No. 52 Effective Date: 4-25-75 The 163 units of multiple at 200' square feet equates to 32,600 square feet or .74 of an acre. The development plan provides several large greenspace areas which with revised grading could meet the recreation open space requirement. The developer has agreed to revise the grading plan within these areas to accommodate this code requirement. FOR COMMISSION ACTION The Commission may consider the following recommendations: 1. The plat be subject to a cash parks dedication. 2. The plat be subject to a cash trails dedication. 3. The developer grade an 8' wide trail pad to the Deerwood School property within the trailway easement. The developer coordinate the alignment, grading and sequencing with the School District. 4. The developer provide a tree protection plan for city review and approval prior to final platting. 5. The developer revise the grading plan providing .74 acres of recreational open space. The revised plan shall be submitted and approved by the City of Eagan prior to final plat. ~1. MEMO TO: EAGAN ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: TOM SCHUSTER, CITY FORESTER JOHN K. VONDELINDE, SUPERINTENDENT OF PARKS DATE: AUGUST 27, 1992 SUBJECT: REPORT ON THE STATUS OF OAK WILT DISEASE IN EAGAN The purpose of this report is to review the extent of oak wilt in the community and in the City park system. The report will attempt to describe the nature of the oak wilt disease and its methods of spread. The report will also review prevention and treatment alternatives and outline preliminary policy and program alternatives for oak wilt management within the City. OAK WILT DISEASE Oak wilt is a fungal disease that kills all varieties of oaks that grow in Eagan. The most susceptible are red and pin oaks; the least susceptible are burr and white oaks. Once a tree is infected with the oak wilt fungus, the tree attempts to block the spread of the fungus by producing substances called tylosis and gums which block the water-conducting vessels of the tree and cause it to wilt. In essence, the tree strangles itself in an attempt to prevent the spread of the fungus. Once infected, the red and pin oaks will die within one year. White and burr oaks on the other hand die much more slowly and sometimes can live with the disease for many years. Oak wilt is generally spread from tree to tree by means of root grafts. Root grafts occur when trees of the same species are growing close enough together that their root systems intertwine and eventually grow together. Thus, what affects one tree will eventually affect any other trees grafted to it. Because root grafts will only occur between trees of the same species, red oaks only root graft with red oaks, white oaks only root graft with white oaks, etc. Therefore, diseased red oaks can only spread the disease through root grafts to other nearby red oaks, and white oaks only to white oaks. When an infection occurs within a stand containing all one type of oak, the disease can easily spread from tree to tree and wipe out the entire stand. New oak wilt infections can also occur when diseased red or pin oaks are allowed to stand the year after they wilt. The fungus will produce fruiting bodies (spores) on fungal mats ~9. under the bark of red and pin oaks. Oak wilt fungal spores can then be carried from these trees to fresh wounds on oak trees of any species. Therefore, white oaks can be infected from the spores of the standing red oak. It is only the red and pin oaks, however, that allow the fungus to produce the spores. Overland spread from red oaks to the other types of oak trees is most likely to occur when there is a fresh wound on an oak tree during the months of April, May and June. Fresh wounds on oak trees, or any tree for that matter, are attractive to insects called picnic beetles. The picnic beetle is not necessarily attracted to oak trees, but is attracted to any tree with a fresh wound that gives off a particular odor. When the insect flies from a diseased tree to a fresh wound on another oak tree, it will carry the fungus on its body and infect the new tree. So while root grafts can only occur between trees of the same species, the overland spread of oak wilt can occur between the red and pin oaks to oak trees of any species provided these trees have been recently wounded. Tree wounds that are more than five days old generally are no longer infection sites since the moisture content of the wood at the point of the wound drops so low that the fungus cannot become established. PREVENTION OF OAK WILT Prevention must be the goal of any oak wilt control program. The key to preventing an oak tree from becoming infected with oak wilt disease is by being careful not to prune or injure it during the months of April, May and June. If wounding occurs during this time of year, the tree wound should be sealed with tree wound sealant or pruning paint as soon as possible. Once diseased trees are located, it's important that the root grafts that may occur between the diseased trees and surrounding healthy trees be physically disrupted. The most efficient way of doing this is through the use of a vibratory plow. A vibratory plow is a self-propelled machine, about the size of a backhoe, that pulls a five-foot deep metal blade through the ground. This blade literally "vibrates" rocks out of its way and severs any root grafts between the tree roots. These root graft barriers are only necessary between diseased trees and healthy trees that are of the same species. A liquid chemical soil sterilant called Vapam can be used to disrupt root grafts in areas that are inaccessible to a vibratory plow. Vapam can be injected directly into the soil in a line running between the trees' roots. Vapam is seldom used however, since its effectiveness varies greatly depending on soil types, i.e., rocks, sand, clay, etc. After root grafts have been disrupted, either mechanically or chemically, diseased red and pin oaks must be removed before the fungal spore mats form. Since these spore mats form on firewood as readily as on standing trees, simply cutting the trees down is ineffective. Therefore, any wood from diseased red or pin oaks to be used for firewood must be covered with heavy plastic during April, May, and June. The plastic will prevent any spores formed 8o on the wood from infecting nearby trees. Careful use and storage of diseased wood can greatly decrease the spread of oak wilt. Currently, there are no chemical treatments available for use on oak trees to prevent oak wilt. While progress has been made to develop fungicide injections to prevent Dutch Elm disease in elms, efforts to develop a similar fungicide for oak wilt have been fruitless. Since oaks are the major component of Eagan's forest cover, it is important to continue to plant them from a perspective of overall landscape integrity. Caution must be exercised, however, to ensure that any newly planted oak trees are properly spaced and of varied species so as not to create a "monoculture" or overreliance on one species. For instance, burr oaks planted in an area where oak wilt is infecting red oaks may be a successful venture, whereas planting red oaks will not. Finally, another key to the prevention of oak wilt is to help keep the trees in an overall state of vigor. This means carefully planning construction sites to avoid soil compaction and fill around the roots of the trees, providing adequate moisture and aeration for the tree roots, and periodic pruning and fertilization. CURRENT STATUS While oak wilt was once contained primarily to red oaks, the past several years has shown a greater occurrence of oak wilt on the burr and white oak species. Staff estimates that there are between 1,200 and 2,000 trees dying from oak wilt each year in Eagan. In addition, there are more than 100 separate infection centers scattered throughout the community. Oak wilt is becoming a particularly serious problem in many of the oak woodlots in the south and east parts of Eagan. Oak wilt infections range from the Winkler-Jackson development in the far southwest comer to the South Oaks Park area in the southeastern end of the City. Infection centers also range from the Blue Cross/Blue Shield woodlot adjacent to the Eagan Maintenance Facility to Wescott Station Park. Virtually every major woodlot south of Yankee Doodle Road has some type of infection center. Those park properties that are known to contain trees infected with oak wilt are Mueller Farm, South Oaks, Northview, Wandering Walk, Thomas Lake, Trapp Farm, Goat Hill, Walnut Hill and Patrick Eagan. As trees in these parks wilt and die, they are removed by City forces providing they are readily accessible. The problem with many of the oak wilt infection centers in these parks and many of the woodlots in the City is that an estimated 30% of the infection centers are in remote areas or on steeply sloped banks that are inaccessible to equipment. `3/. Oak wilt is a much easier disease to deal with when it affects trees in residential neighborhoods because the trees generally are spaced further apart, thus making it easier to get equipment between the homes and through the yards. The construction of the homes themselves removes many of the trees and the installation of utilities creates root graft barriers. Unfortunately, the removal of ground covers, the excavation and compaction of soil on construction sites causes stress to nearby oak trees making them more susceptible to oak wilt and other tree diseases. It is in these areas, though, that the potential for oak wilt control seems to be the most promising. COMMUNITY IMPACT The effect of losing mass quantities of oak trees is a general reduction in the quality of the forest canopy in Eagan. This will result in reduced wildlife habitat, less species diversity (which could lead to diseases affecting other tree varieties) and an overall decrease in the aesthetic qualities of many of Eagan's most beautiful areas. On an individual level, this means reduction in property value, the loss of shade, and an increase in heating and cooling costs to our residents. As the Commission is well aware, the oak tree is a symbol of Eagan's growth and development, and yet it is these very trees that are now threatened by oak wilt disease. If we take action soon, we could drastically reduce the number of trees dying of oak wilt each year. A tree disease control program could possibly reduce oak tree losses to a few hundred annually, rather than the 1,500 to 2,000 we stand to lose if no control program is initiated. If left untreated, many woodlots will likely lose most of their oak trees. Since oak is the major cover type in many areas in Eagan, this could result in drastic changes in Eagan's forest canopy. And while there will always be isolated trees or groups of trees that will be unaffected by oak wilt, any area that has a high population of oak trees is threatened. It should be pointed out that even though oak wilt is a serious threat to the community's oak trees, it is not as likely to be as devastating as the nber of elms killed by Dutch Elm Disease. This is principally due to the varied metho s of spread described earlier. But because oak trees have higher emotional, aesthetic an financial values, their loss could be even more devastating than the loss or our elm trees. POLICY AND PROGRAM ALTERNATIVES Background In the early 1970's to mid-80's when the State of Minnesota mandated that municipalities institute shade tree control programs, City tree inspectors would routinely inspect the trees in the designated control areas. But, because Eagan was not developed nearly to the extent ~z. that it is now, those control areas were much smaller and somewhat scattered throughout the City. In the past several years because of the vast development in Eagan, our effective control zone could essentially include the entire 34.5 square miles of the City. However, because budgets and staffing have not kept up with the growth of the residential areas in the City, it is no longer possible to routinely canvas the entire City inspecting for diseased trees. Our current approach is to respond to inquiries by the public and to perform individual inspections and identify diseased trees for individual homeowners. When there seems to be enough interest in one area, we will canvas that particular neighborhood and identify diseased trees and let the homeowners know the status of their oak trees. With this as a brief background, the following sections will review alternative policies and programs that can improve the City's efforts to control oak wilt in the future. Informational Resources The use of public information resources is considered to be one of the most cost effective means for engendering the assistance of the public in the fight against oak wilt. To this end, City staff has attempted to educate residents about oak wilt through articles in the Eagan Newsletter and in the Chronicle and This Week newspapers. Staff has also prepared a series of Forestry brochures, one of which deals specifically with tree diseases including oak wilt. By responding to approximately 300 citizens' requests dealing with oak wilt each year, the City Forester meets on site with residents to discuss the oak wilt situation on a one to one basis. From time to time, Forestry personnel will staff displays and answer questions at various workshops. In 1991, this happened at the KARE 11 Health Fair at two locations in Eagan. Earlier this year, Eagan Forestry staff and Apple Valley staff hosted a community seminar and workshop on lawn and tree care at Valley Middle School in Apple Valley. In addition to the information available through our City, residents can also make use of resources available through the Minnesota Departments of Natural Resources and of Agriculture, as well as the Dakota County Extension Service and the University of Minnesota. These agencies provide most of the research and numerous publications dealing with oak wilt management. Articles concerning oak wilt have also appeared in the Minneapolis and St. Paul newspapers. And stories about oak wilt have been broadcast on local television news programs. Billboards reminding people to protect their oaks by avoiding pruning during May and June have even been put up along the interstate highway system. In the future, the Forestry Department will continue to emphasize the use of information resources to educate the public about the oak wilt problem in Eagan. This public program is regarded as one of the most cost effective approaches to achieving abatement in residential areas and for encouraging proper pruning and storage practices. Regulation and Enforcement Eagan's City ordinance still provides for the ability of City tree inspectors to condemn trees on private property and to require their removal. This is a part of the ordinance that has not been as actively enforced with the decline of Dutch elm disease in recent years. Unfortunately, with the emergence of oak wilt as a new community problem, there is now a need to augment staff levels in order to keep pace with disease eradication on City property and on private property. The ideal situation, of course, would be that City staff could remove or treat all diseased trees on public property and identify and require removal or treatment of all diseased trees on private property. To accomplish this, though, would require a significant increase in staffing levels and funding of contractual budgets. An effective program would need the services of a full-time seasonal tree inspector on staff from early March through late October. This individual's duties would include firewood inspection, disease tree identification and inventory, notification of property owners, arranging for trenching or vibratory plowing for root graft disruption, and re-inspection for compliance with the ordinance. Inspection of trees for oak wilt must be done systematically throughout all residential areas of Eagan. Diseased trees must be identified and homeowners notified of the need to have these trees treated or removed. After the time for removal allowed by City ordinance is expired, reinspection of identified diseased trees must occur. If the diseased trees are not removed, the City should, under the provisions of ordinance, proceed with removing these trees and assess the cost of removal to the property owners. A number of undeveloped woodlots such as the Blue Cross/Blue Shield property or the woodlot between Plaza Drive and Galaxie Road currently present problems with compliance of City ordinance. While Eagan's City ordinance provides for a program of inspections, notification, removal and enforcement, this program is not aggressively being carried out. If Eagan is to truly have an impact on its oak wilt problem, resources will have to be put into a comprehensive program of enforcement and eradication on private property. Cost Sharing Programs Currently, there exists no type of community assistance cost sharing programs available to people in Dakota County. During the height of the Dutch Elm disease crisis in the 1970's and early 1980's, the State of Minnesota helped fund community tree disease abatement programs. When the State Shade Tree Program was all but eliminated, reimbursements discontinued. Only large cities, such as St. Paul and Minneapolis had municipal budgets large enough to continue to assist residents with removal of trees from private property. 3~ With the ever increasing death of oak trees, in and around the metro area, the State of Minnesota is beginning to offer cost share programs to select communities once again. The north metro area referred to as the Anoka Sand Plain is currently suffering even greater losses of oaks than in Dakota County. For this reason, the State has targeted the north metro area for its first assistance program. In 1992, the State has about $175,000 earmarked for oak wilt suppression programs. It is expected that this funding will be available and may increase to the point that Dakota County communities may be eligible for program funding as early as 1994. Should this funding be offered, the City's program will have to be aggressively carried out to meet criteria for participation in this program. Assuming Eagan participates in the state program, funding may be made available to the community for staffing and equipment, and may extend to financial assistance for private property owners. Under such a program, a year-round staff of at least three full-time employees would be required for the removal of dead trees on private property. Root graft barrier work could either"be conducted by City staff with the purchase of a vibratory plow or continue to be contracted out through tree service companies. Public Property Management In addition tc enforcement activities, Forestry staff would also have to be adde 1 to ensure that trees on public property are removed within the time frame allowed by the ordinance. At least two additional year-round forestry technicians would be needed to help remove the estimated 120 trees dying in our park system each year. In addition to the added staff, specialized equipment would also be needed for the skidding and loading logs. This would require the availability of a bobcat-type skid loader or log skidder specifically dedicated to this program. As infection centers are identified within our park system, additional monies will have to be spent for the contractual work of installing root graft barriers. It is not unreasonable to expect cash outlays of $2,000 to $3,000 each year for contractual services of this kind. For example, City staff recently contracted to have root graft barriers installed south of the pavilion at Thomas Lake Park. Approximately 20 red oaks had died in an infection center in the ,park. The cost for the root graft barrier was $750. Staff has also received an estimate of $1,500 to treat the woodlot at Northview park. There appear to be at least three separate infection centers in that park affecting approximately 60 trees. Similarly, oak wilt is affecting trees near the entrance of Trapp Farm Park, as well as on the hill north of the pavilion. Currently about 12 trees are infected with oak wilt. The cost of treatment at Trapp Farm is estimated at $1,000. Residents of Trotters Ridge have also requested that our department treats infected trees behind their property in Wandering Walk Park. Unfortunately, the Forestry budget simply does not allow for a comprehensive root grafting project in all areas of disease on public property at this time. Finally, trees lost to oak wilt in park areas may need to be replaced. Each year, about a dozen trees die from oak wilt in maintained park areas. The cost of replacing these trees is about $1,200. Obviously, trees planted to replace the oaks must be disease resistant species. The bulk of the oak mortality in the park system occurs in non-maintained areas. As noted earlier, removal of these trees will be difficult. City staff has not replaced trees in unmaintained areas in the past. If the Forestry Department were to replace the trees removed from these unmaintained areas, the replacement costs could approach $10,000 each year. Follow up maintenance of these replacement trees would also be hampered by their remote locations. CONCLUSION Clearly, the time has come to address the oak wilt problem in the City of Eagan. If no action is taken, the community will be faced with an accelerated loss of trees in the City's parks, private woodlots, and residential areas. In order to have a successful oak wilt suppression program, the City will need to implement a multifaceted public policy including public education, inspection, enforcement, disease abatement, and public forest management. COMMISSION ACTION Staff is not requesting any specific action at this time. This report represents a cursory assessment of the oak wilt problem in the community along with some preliminary alternatives for addressing this issue in the future. Staff would appreciate the opportunity to discuss this matter with the commission and to gain their input on future directions concerning this public policy issue. Tom Schuster John ~tWonbeLinde City Forester Sup tendent of Parks TS/JKV/sb 29wp.advis.223 MEMORANDUM TO: KEN VRAA, DIRECTOR OF PARKS AND RECREATION FROM: JON OYANAGI, RECREATION SUPERVISOR DATE: AUGUST 26, 1992 RE: SUMMER PROGRAM REPORT The major portion of my duties during the summer is the implementation of the adult slowpitch softball leagues. Preparations begin in January, registration happens in March and the season runs from late April through the beginning of August. This year, five weekends were utilized for department-run tournaments and play-offs. Here are some fun facts to know and tell. 1992 1991 Total number of teams Men's 140 139 Women's 25 27 Co-Rec 53 40 Total 218 206 Total number of leagues: 26 Total number of games: Regular season 1387 Tournaments 405 Total games 1792 Estimated number of players: 3270 15 x 218 teams Estimated revenue: $80,000 (includes $5,700 in outside players fees) Estimated expenditures: $66.000 Net Revenue $14,000 Rain-out evenings: One Player ejections: Five (nine games missed) The weather cooperated to cause the rescheduling of only one evening. The rain was regular, but never interfering with league play. Also, the cool temperatures made for comfortable playing conditions and relatively few bug problems. Summer Program Report August 26, 1992 Page 2 The Outside Player Fee was instituted this year. Of course, teams complained about an extra fee. One complaint I feel deserves attention was from women's teams that have decreased in numbers through recent years. Their argument is that they need help recruiting players just to form a team and the outside player fee hurts this process. If we want to maintain or increase the number of teams in our women's leagues, I would suggest dropping the outside player fee and even go so far as to suggest opening the eligibility boundaries to the "South of the River" communities. This would need to be acceptable to those communities and not interfere with their attempts to conduct women's leagues. Overall, this season was the smoothest of my four as League Director. The generally positive behavior of players, the great weather, the capable performance of the umpires and the quality maintenance of the fields created a great experience for all. The summer concludes with the 70 team Men's Class D, Region IV Tournament and the 44 team Men's Industrial Class D State Tournament. Fall Softball began August 17, 18 and 19. Baseball Hitting Camp One hundred fifty campers learned hitting the "Wildcat" way from Coach Bob Sadek of Eagan High School. Coach Sadek and his staff had eight hours of drills to help ballplayers improve and learn correct techniques for swinging a hot bat. This year we hired the staff as seasonals. The administrative headaches created will warrant an evaluation of this arrangement and how best it can work. Problems stemmed from ti anslating contractual pay per registration to a wage or salary. Camp Creative An average of 45 youth attended the weekly adventures at Camp Creative. Each week a different theme led them into a variety of crazy activities. Music, art, drama, food, video and making a mess were some of the topics. A great staff helped the participants enjoy their own creative juices. In-Line Skating Ussons Fifteen individuals took part in this first time endeavor. Though not advertised in our summer brochure, we did flyer the Summer in the Park sites and had the instructor in the Fourth of July parade handing out flyers. In the process, his unit won first place in their division. We will try these lessons again this fall with a description in the brochure. The instructor is the same person teaching ice skating lessons. 41. Summer Program Report August 26, 1992 Page 3 Movies in the Park Thirty to forty-five people attended each Monthly Moonlight Movie on Mondays. Great weather rewarded the outdoor cinema buffs who saw movies about adventure sports, the making of the Empire Strikes Back and children's favorites. Walk and Bike Clubs Both clubs have seen growing interest but still sporadic attendance. Monthly and weekly activities see two to six participants. The monthly meetings draw three to twelve attendees. Despite the low numbers, both groups continue to plan a list of appealing activities. Each quarter we seem to add to the growing mailing list. 3-On-3 Basketball Six adult teams played Mondays through the summer. Sky Hill and Bridle Ridge parks were utilized. Teams maintained a recreational attitude and enjoyed a great summertime workout. The cooler weather helped this typically sweltering program. Two rainouts shortened the season. One youth team registered and was refunded their entry fee due to the lack of other teams. JO/nh cc Dorothy Peterson, Superintendent of Recreation MEMORANDUM TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: ~p U~ DOROTHY PETERSON, SUPERINTENDENT OF RECREATION DATE: AUGUST 28, 1992 RE: SUMMER PROGRAM REPORT This report reviews activities, events and facility usage experienced in 1992. Comparison to previous experience is made. Because quantity is just one aspect of evaluation, quality will be addressed also. Tennis The Department's tennis program is multi-faceted. It seeks to provide opportunity to learn and to play the game for children and adults. Organizationally, the Department employs a seasonal tennis director. This same individual has held that position for the past three years. She is a professional tennis instructor and locally works as the varsity coach for Burnsville High School's girls team. Having observed Patty Mraz teach, my assessment is she teaches people how to play tennis. There is a tremendous difference between this approach and one in which tennis is taught to people. Recreation staff has final approval on tennis program offerings and the goals and objectives of the program. The tennis director is responsible for the specifics of the instructional program. This summer, a total of five instructors were employed. With morning, afternoon and evening tennis activity in progress, that number of instructors was required. The 1992 tennis staff happened to be all female. A goal for 1993 is to provide at least one male instructor for the program. Rain had a significant impact on tennis in 1992. To our knowledge, each class that was rained out had an identified rain make-up. The responsibility to attend the make-up lesson was the student's.

Previously beginner, advanced beginner and intermediate lessons were offered. Participation in intermediate lessons was weak. The new format was to offer beginner and beginner 2 lessons. Intermediates were encouraged to participate in an intermediate tennis camp which also was new. The number of adult lessons offered was cut back to a level that history from previous years demonstrated to be sufficient. All sections offered were filled. New, early morning and late afternoon drills were offered for adults. The targeted audience was the tennis buff who already played and was looking for a concentrated skills workout. The South of the River Tennis Camps are geared toward middle school/junior high and junior varsity level high school players. Typical intermediates fit well in the middle school group. Emphasis is on fundamental skills with various creative match-like drills, contests and games added for good measure. The Men's League was new. In essence, it was a loose association of tennis players. A schedule of matches was drawn. Every third week the group played doubles rather than singles. No scores were reported nor standings kept. The only requirement was that if a player had a conflict and could not play, he call his opponent to inform him! The Co-recreational League was severely affected by rain. Three of the first six nights of play were rained out. It took the rest of the summer for teams to scramble to make up those matches. This league continues to be an Eagan-Inver Grove Heights League. The league was smaller than in 1991. Several former players indicated that they were moving to more competitive play. Summer Program Report August 28, 1992 Page 3 The Department held two youth tennis tournaments. The USTA event in June attracted participants from the metro area and beyond. Eagan had 9 entries, Burnsville had 13 and Apple Valley had 7. Youth from Brainerd and Mankato competed. Metro area communities from Stillwater to Deephaven to New Hope were also represented. Athletic Field Reservations Department practice for use of athletic facilities is: Facility classification for level of maintenance and use purposes Class A: Northview Athletic Softball Northview Athletic Soccer Northview Athletic Tennis Courts Goat Hill Park Baseball Rahn Athletic Softball and Baseball Class B: Eagan High School Baseball Eagan High School Softball Dakota Hills Middle School Baseball Class C: Elementary School Fields Neighborhood Park Fields The classification speaks toward the facility itself; ie. ballfield fully fenced, lighted and the. level of maintenance provided and a ballfield attendant on duty during activity. Class A sites meet these criteria. Class B sites are not lighted or fully fenced Games are played without a ballfield attendant on duty. However, the bases may be set out daily by an attendant. Class C sites received daily infield drags. Class A facilities are used by Department adult programs, Eagan High School, Dakota Hills Middle School, travel sports and space available "challenge" games. Class B facilities are used by Eagan High School, Dakota Hills Middle School and age appropriate Eagan Athletic Association programs. For example, 6 year old mites do not require 90' base paths. Class C sites are used by Eagan Athletic Association programs and space available independent groups such as the 4H. The field use calendar is established by placing Department, high school and middle school games on first. Field assignments are presented to travel sports and EAA. From the schedules of games, each facility is "booked" date by date.

Fields at Eagan High and Dakota Hills Middle were available for community use for the first time in 1992. It was just in the nick of time to correspond with increased numbers of youth softball and baseball teams. The Commission should be aware, however, that every inch of available field space was used in 1992. Staff will renegotiate with Unisys for use of their 4 fields for youth programs. A maximum of 5 new school ballfields will come on line, however, some fields may be rotated out for maintenance resulting in no gains, hopefully not a loss! Concessions The concession operation returned to the concession room in 1992. Sales achieved the level experienced prior to the fire. Benefiting from concessions for the Region 1AA fast pitch softball tournament, the balance sheet through the end of July showed gross receipts of $7,735.00 with expenditures for product and salaries at $5,854.00. Net revenue was $1,881.00. The Men's Region D Tournament in mid-August netted approximately $600,00. However, purchases were made to also cover the State Industrial D Tournament on August 29 and 30. The true bottom line won't be known until after that tournament. 1/.

During the first year staff recognized that severe parking problems occur at Rahn Athletic when sand volleyball and a full slate of softball games are scheduled on the same evening. With that in mind, the Department was still able to offer sand volleyball on two evenings. Twenty-one (21) teams selected sand volleyball as a summer recreation activity. Ten teams played in 1991. The season ended the third week in August. Shorter hours of daylight dictates the length of the season. Sand volleyball has the potential to grow significantly. That potential cannot be fully tapped at Rahn Athletic due to the parking dilemma. Staff will be present at the September 3 meeting should the Commission request additional information or clarification.

Registrations increased dramatically in a few programs and decreased in others. A staff of 36 including 1 program assistant, 13 leaders, 18 assistants and 4 substitutes provided activities for the youth of Eagan. Again this year, the staff proved to be one of the most experienced and cooperative I have ever worked with. Several employees have worked for more than five years. A fee of $10.00 was charged for Summer in the Park and a fee of $5.00 for the Playwagon. In the past, there has not been a fee charged for either of these programs. A total of 878 children were registered in Summer in the Park compared to 1,173 in 1991 and 821 in 1990. The Playwagon registered 122 children compared to 148 in 1991 and 73 in 1990. The decrease in registration numbers may be attributed to a number of reasons including the introduction of fees. • When there is no fee charged, people will register for a program even if they only show up one time. • Families, registered for other programs (ex: swimming lessons, Eaganettes) that occurred at the same time as Summer in the Park. • Child could only show up once a week; therefore, they felt they wouldn't get their money's worth. 47 1992 Summer Program Report August 27, 1992 Page 2 SIP Total = 753 10 sites 1991 Total 1991 Average 1992 Total 1992 Average Park Registration Attendance Registrations Attendance Blackhawk 84 35 52 24 Evergreen 91 34 56 26 Northview 151 35 98 (est.)40 Quarry 37 13 17 10 Rahn 104 30 81 42 Ridgecliff 117 42 116 61 Sky Hill 71 25 64 31 Walnut Hill 160 32 105 35 Bridle Ridge 163 40 114 45 AM South Oaks 57 16 50 25 AM Sky Hill 62 29 40 21 5 & 6 AM Goat Hill 76 31 85 30 5 & 6 PM Summer in the Park 1,035 753 SIPS & 6 138 125 1,173 878 While total registration decreased at all sites except Goat Hill, the average attendance increased at most sites. Bridle Ridge and South Oaks continued to be popular morning sites while Ridgecliff and Northview saw steady attendance for afternoon sites. The SIP sites for 5 & 6 year olds continued to be popular as well. Quarry Park attendance has decreased again this year. Plans are under way for trying to increase their attendance. 1992 brought changes in the attitudes of children who attended SIP. Staff found that older children (10-12) did not want to participate with 6-9 year olds and vice versa. Staff is exploring offering 2 separate sites for the 10-12 year old age group. Northview Park is being considered for a morning site and Sky Hill Park for an afternoon site. 4-2. 1992 Summer Program Report August 27, 1992 Page 3 An alternative to going on field trips was offered in 1992. Field trip optional sites were available during four SIP field trips. Registrations were much lower than anticipated, therefore, staff recommends not offering this alternative for 1993. Field trip and special events were well attended. The Minnesota Twins Game and Pizza Party day were the highlights of the summer. On Pizza Party Day over 525 children plus staff enjoyed the 139 pizzas that were ordered. Bob the Beachcomber, who performed at the Beach Party, was also a favorite of the children.

This program increased to 165 participants compared to 144 in 1991, 143 in 1990 and 94 in 1989. Over 140 children marched in the Fourth of July Parade and 149 participated in the Recital. Over 400 people (moms, dads, grandparents) were in attendance at the Recital. The program has grown to a point where an additional instructor was hired during the second week of the program. Staff is currently looking at modifying the class schedule as well as the set-up for the recital to best meet the needs of all participants. Four sections of Tiny Tots for 3, 4 and 5 year olds were offered and all filled to capacity. A total of 80 children were registered compared to 72 in 1991 and 83 in 1990. Lower registrations were anticipated for 1992 as has happened for the past two years. Demand for classes increased during 1992 and 1993 may need additional classes. The Goat Hill and Bridle Ridge areas are asking for additional classes. Staff will evaluate next spring whether the number of sections offered will change. A basic instructional program for five year olds was offered for the first time in 1992. The demand from parents for this program was one reason it was offered. Ninety-seven five-year olds signed up for one of their first experiences playing organized sports. The five year olds even made it on T.V. Good Company's Gary Lumpkin made a 6-7 minute video on what it's like to play T-ball. In a very entertaining video the children try to catch a ball in the air, run the bases the wrong way and hit from a tee. T-ball was also offered for 6 and 7 year olds. Fifty-four children were registered for a total of 151 children in T-ball compared to 72 participants in 1991 and 58 participants in 1990. In other summer youth programs, participation was steady. Games Kids Play, Fitness and Fun, Preschool Movement and Creative Expressions were all well attended. Summer Fun Day trips were again popular and plans are to expand for 1993. Nature Camp was held for the second year with additional sections added. Sixty-three children, compared with 40 participants in 1991, enjoyed 2 days of nature at Thomas Lake Park. Naturalist Tim Lundahl led the children through insect hunts, making stick bread, making leaf print t-shirts and playing nature related games. 1992 Summer Program Report August 27, 1992 Page 5 Youth Safety Camp The second annual Youth Safety Camp was held on August 10, 11 and 12 at Thomas Lake Park. The camp was sponsored by the Eagan Fire, Police and Parks and Recreation Departments that included 79 eight and nine year olds. Safety sessions revolved around electrical safety, water safety, train safety, seatbelt safety, pediatric medicine and a K-9 demonstration. The camp is becoming a popular idea with Eagan receiving requests from other communities on how to put on a Safety Camp. These requests have resulted in staff receiving an invitation by the Minnesota Safe Kids Coalition to be on a committee to create a Safety Camp Manual and Training Program that other communities and states could use as a guide. Sports and Games Camp Twenty-eight children attended the camp that focused on baseball/softball, football, basketball and other traditional games. The camp was held August 3-7 from 9:30 - noon at Bridle Ridge Park. A highlight for the participants was a Pizza and Ice Cream Party held on the last day. There were eleven requests from families for program fee assistance. A total of $340.75 in registration fees were assumed by the Department to cover these requests. The 1992 summer programs were again very successful. Despite the cool and rainy weather, the attendance was high. While registrations appeared to decrease in Summer in the Park, other programs, like Eaganettes and T-ball, had increased registrations. Each year brings a new set of challenges. 1993 will be no exception. Staff will need to explore new and expanded offerings for pre-schoolers as well as the ten - twelve year old age group. Program fees will also need to remain close to what is currently charged. 1992 parent evaluations revealed that participants appreciate the present registration fees and would like to see more low-cost programs. PN/nh MEMO TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: RICH BRASCH, WATER RESOURCES COORDINATOR DATE: AUGUST 26, 1992 SUBJECT: EXECUTIVE SUMMARY FOR MET COUNCIL'S INTERIM STRATEGY TO REDUCE POLLUTANT LOADS TO MINNESOTA RIVER Attached is an Executive Summary for the Met Council's strategy to reduce pollutant loads to the Minnesota River. I've also attached a copy of the Met Council document that explains the full strategy. This is intended to be an informational/discussion item at the September 3rd Commission meeting. Thanks. Rich Brasch Water Resources Coordinator RB/sb Attachments INTERIM STRATEGY TO REDUCE NON-POINT SOURCE POLLUTION TO THE MINNESOTA RIVER EXECUTIVE SUMMARY THE ISSUE In 1988, a lawsuit was filed by the U.S. Environmental Protection Agency (EPA) against the State of Minnesota regarding violation of federal water quality standards in the Minnesota River. In an action related to the suit, the EPA and the Minnesota Pollution Control Agency (MPCA) agreed in 1990 on a goal to reduce non-point source pollution in the Minnesota River by 40% from pre-1980 levels. The two agencies have set 1996 as the target date to achieve this goal. THE RAMIFICATIONS If this goal is not reached by 1996, the EPA and MPCA may require: 1. A moratorium on land developmert within the Minnesota River Basin; or, 2. Expensive improvements to the Blue Lake and Seneca Wastewater Treatment Plants which will only have a minimal positive impact on the Minnesota River. It is possible that water quality standards will not be met even after the facility improvements are made. These facility improvements, however, will be paid for by all existing and future sanitary sewer users in the Metropolitan Area; or, 3. The Metropolitan Council and the Metropolitan Waste Control Commission to pay a fine for failure to make efforts to accomplish the 40 percent reduction goal; or, 4. A combination of the above three (3) options. THE INTERIM STRATEGY To begin to reduce urban non-point source contributions, the Met Council has adopted an interim strategy containing three components. These components, and Eagan/s compliance status with each, are described below: 1. Requirement. Local governments in the Minnesota River Basin must adopt design standards for new stormwater ponds that will reduce the contaminant loadings from surface water runoff. One set of design criteria that is widely accepted is from the National Urban Runoff Program (NURP). These criteria, or similar specifications which are equally effective, should be incorporated in the stormwater plan of every local government in the Minnesota River Basin. At the present time, 1 -4.,. this policy does not direct the retrofitting of existing stormwater ponds. This criteria must be met by September 30, 1992. Compliance Status. Eagan has already incorporated NURP standards into its Water Quality Management Program. These standards guide the design of treatment ponds required as mitigation for new developments, as well as treatment ponds that the City constructs as public improvements. 2. Requirement. Local governments in the Minnesota River Basin must also include in their stormwater plans the MPCA's urban "best management practices," titled "Protecting Water Quality in Urban Areas" or an equivalent set of standards. These standards are to be used for all new or redeveloped land development. Local governments must also notify their residents of the EPA/MPCA 40 percent reduction goal, "best management practices" to achieve this goal and available resources if additional information is needed. These requirements must by met by September 30, 1992. Compliance Status. The Eagan Water Quality Management Program presently includes many of the stormwater as well as housekeeping "BMP's" required by the Met Council. While Eagan does not utilize all of the identified BMP's in its program, the ones it does Use are considered among the most effective. These include detention ponds, extended detention basins, wetland treatment, skimmers, filter strips, vegetated swales, education on fertilizer management and vegetative litter control, catch basin cleaning, street sweeping, and de-icing chemical storage. A letter from the City to the Met Council certifying that we are in compliance with this provision is required by September 30, 1992. The resident notification requirement will be met with the publication of an article in the September, 1992 City newsletter. 3. Requirement. All local governments in the Minnesota River Basin must adopt the Department of Natural Resources' shoreland regulations as found in the "Statewide Standards for Management of Shoreland Areas" as prescribed by the timeline in (Minnesota Regulations Parts 6120.2500 - 6120.3900) and consistent with the DNR's implementation strategy. Compliance Status. The Department of Community Development is overseeing adoption of these regulations by the City. The deadline for adoption is January 4, 1993.

Fifth St., St. Paul, MN 55101 Publication No. 640-92-038 SUMMARY OF TILE POLICY ISSUE In 1990 the U.S. Environmental Protection Agency (EPA) and the Minnesota Pollution Control Agency (MPCA) agreed on a goal to reduce nonpoint source pollution in the Minnesota River by 40 percent from pre-1980 levels. The two agencies have set 1996 as the target date to achieve this goal. To accomplish this goal, current land development and agricultural practices must be altered to restrict nonpoint source pollutants from entering area water bodies. THE PROBLEM The U.S. Environmental Protection Agency (EPA) and the Minnesota Pollution Control Agency (MPCA) in 1990 established a goal of reducing nonpoint source pollutants in the Minnesota River by 40 percent from pre-1980 levels to meet state water quality standards. This goal is to be accomplished by July 1, 1996. See exhibits A and B. If this goal is not reached by 1996 the EPA and MPCA may require: 1. A moratorium on land development within the Minnesota River Basin; or, 2. Expensive improvements to the Blue Lake and Seneca Wastewater Treatment Plants which will only have a minimal positive impact on the Minnesota River. It is possible that water quality standards will not be met even after the facility improvements are made. These facility improvements, however, will bi: paid for by all existing and future sanitary sewer users in the Metropolitan Area; or, 3. The Metropolitan Council and the Metropolitan Waste Control Commission to pay a line for failure to make efforts to accomplish the 40 percent reduction goal; or, 4. A combination of the above three (3) options. The Metropolitan Council has documented an increase of nonpoint source pollution to area water bodies. These added pollutants reduce the recreational value and accelerate the eutrophication of area water bodies. Water quality standards in the Minnesota River are violated as a result of nonpoint source pollution generated from Greater Minnesota as well as the Twin Cities Metropolitan Area. Exhibit C lists those local governments in the Minnesota River Basin. The increase of nonpoint source pollutants to area water bodies can be traced to two primary sources: land development and agriculture practices. Land development or urbanization, generally increases both the volume of runoff as well as the concentration of pollutants in the runoff. This happens with the conversion of land to hard surface and by the destruction of wetlands. Detention ponds or artificial depressions can help mitigate these impacts. The best designed ponds, however, will not reduce the increased volume of runoff following urbanization nor will they totally remove the additional pollutants following urbanization. An increase in runoff volume, total phosphorus and other pollutants are the results of urban development. Agriculture is the predominant land use in the Minnesota River Basin and the major contributor of nonpoint source pollutants. Nonpoint source pollution from agriculture occurs as a result of intensive land cultivation and husbandry practices and shows up in three basic forms: soil erosion; agriculture supplements such as nutrients, pesticides and herbicides; and animal waste products. Each of these 1 sources fill area water bodies smothering aquatic life, change the aquatic environment by limiting light penetration of the water, and result in the transmission of toxins to area water bodies. The Twin Cities Metropolitan Area is fortunate to have an abundance of lakes and rivers. These water bodies provide the area with recreational, aesthetic and educational benefits envied by other parts of the United States. Preservation of these water bodies and the associated wildlife habitat is a major component of the Council's planning framework. Measures to preserve and enhance the environment can be found in all of the Council's major system and policy plans. Policy 7 of the MDIF states that the Metropolitan Council: supports the maintenance of environmental quality throughout the region and will support programs or strategies to maintain or improve the natural environment (page 16). Reducing nonpoint source pollution to area water bodies has a number of positive outcomes. Reduced nonpoint source pollution has an overall positive effect on the environment, improves the water quality in lakes, wetlands and floodplains and allows for fishable and swimable water bodies. Water resource management has historically focused on point sources such as wastewater treatment plants and industrial facilities. Efforts to reduce pollution from point sources has been effective. Nonpoint source pollution abatement is the next challenge that must be addressed to ensure that water bodies in this metropolitan area are protected. EXISTING LEGISLATIVE AND POLICY STRUCTURE FOR ADDRESSING THE NONPOINT SOURCE POLLUTION PROBLEM The Minnesota Legislature Two pieces of legislation have been passed in the last decade that set a framework for addressing the nonpoint source pollution issue. However, it will take several years to put this framework in place and will require local governments to extensively revise their surface water management plans and activities. Watershed Planning Legislation In 1982 legislation was passed requiring Watershed Management Organizations (WMO) to prepare watershed plans that addressed water quality issues. Under this legislation each WMO is to prepare a plan that states objectives and policies for water quality and identifies alternatives for improving water quality and methods of implementation. These plans are to be reviewed by the Metropolitan Council "in the same manner and with the same authority and effect as provided for the council's review of the comprehensive plans of local government units" (Minnesota Statutes, section 103B.231 subd. 8 (1990)). The Council is required to determine whether the watershed plan conforms with the management objectives and target pollution loads stated in the Council's water resources plan prepared pursuant to Minnesota Statutes, section 473.157. Local Government Planning As a part of the WMO planning process described under Minnesota Statutes, section 103B.201, each local government will be required to prepare a local water management plan, capital improvement 2 j. program and official controls necessary to implement the watershed plan. As part of the local water management plan, the local government will need to define water quantity and quality protection methods adequate to meet performance standards established in the watershed plan. Local governments will also be required to amend their local comprehensive plans to reflect the contents of the watershed plan. Local governments will have two years to amend their comprehensive plans from the time the WMO planning process is complete. Under rules currently proposed by the Board of Water and Soil Resources (BWSR), WMOs have until 1995 to complete their plans. The earliest local governments are required to revise their comprehensive plans is 1997. It could take several years beyond 1997 to implement local government plans. The second piece of legislation is Minnesota Statutes, section 473.157, that requires the Metropolitan Council to prepare a water resources plan that includes management objectives and target pollution loads for watersheds in the metropolitan area. From this plan WMOs will advise local governments of their target pollution loads. Local governments will revise their stormwater management plans to include implementation steps that assure the target pollution loads are met. The Metropolitan Council has set as a priority developing the target pollution loads for watersheds tributary to the Minnesota River. This is a priority because of the urgency to meet the EPAIMPCA reduction goal of 40*percent by 1996. Target pollution loads for Bevens, Carver, Chaska and Sand Creek watersheds will be developed by 1992. Pollution loads for other watersheds in the Minnesota River Basin will be developed by mid-1993. The Council will also be actively pursuing the development of target pollution loads for all watersheds in the Twin Cities Metropolitan Area. The Minnesota Pollution Control Agency The Minnesota Pollution Control Agency is in the middle of a multi-year river basin-wide assessment project to evaluate the current condition of, and source and type of pollutants entering the Minnesota River. The Minnesota River Assessment Project (MRAP) is designed to identify the sources of pollution threatening the health and vitality of the Minnesota River. The study involves over a dozen organizations working in concert with local governments from Lac Qui Parle County in southwestern Minnesota to Jordan. The goal of MRAP is to assess the water quality, aquatic communities and current land uses in the Minnesota River system. This information will be used to develop specific water quality goals and to identify programs and best management practices that can help reduce nonpoint source pollution. An implementation plan will eventually be developed that comprehensively addresses the nonpoint source issue in both the metropolitan and outstate areas of the Minnesota River Basin. It will take the MPCA until mid-1993 to complete the assessment phase. The MPCA is also now forming an implementation committee (MRIP) comprised of various interest groups throughout the Minnesota River Basin. The implementation committee has been directed to develop a strategy that most efficiently reduces nonpoint source pollution to the Minnesota River. The Board of Water and Soil Resources The Board of Water and Soil Resources is the primary state agency responsible for surface water planning and is the lead agency responsible for carrying out many of the administrative aspects of the recently passed Wetland Conservation Act of 1991, better known as the "no-net loss" legislation. The act provides landowners with three options for preserving or enhancing wetlands: the wetland 3. preservation areas option; the permanent wetland preserves option; and the wetland establishment and restoration program. If a land use practice requires the taking of a protected wetland the legislation requires a 1:1 and a 2:1 mitigation of wetlands in rural and urban areas respectively. Wetlands perform essential hydrologic and water quality functions such as lowering of flood peaks, providing interchange between surface water and groundwater, and filtering and absorbing pollutants. Because of these functions, wetlands are critical for reducing nonpoint source pollution to area lakes and rivers. The Metropolitan Council In September, 1988 the Metropolitan Council adopted its Water Resources Management Wastewater Treatment and Handling Policy Plan (hereafter the policy plan). Local governments were notified of the policy plan contents in the April, 1989 systems statement and pursuant to the Metropolitan Land Planning Act, had nine months to amend their comprehensive plans. The need to reduce nonpoint source pollution to the Minnesota River Basin through regulating land development is documented in the Council's policy plan: [I]if nonpoint source pollution in the Minnesota River is not dealt with effectively, the Blue Lake and Seneca Wastewater Treatment Plants would possibly have to continually increase their treatment level to where the costs would far exceed the benefits in improved water quality. This would result in very substantial outlays for both capital and operations to compensate for insufficient reduction in nonpoint source pollution. Local units of government must understand that use of land can have important and damaging impacts on water quality. The impacts must be prevented or at least minimized through land use regulations and proper water runoff management (p. 9). Policy 1-1 of the Council's Wastewater Treatment and Handling Policy Plan states: [T]treatment levels required for wastewater treatment plants in the metropolitan system should clearly recognize the need to control both point and nonpoint sources of pollution from within and outside the Metropolitan Area (p. 9). The Council has actively pursued the implementation of its policy to reduce nonpoint source pollution to area water bodies. The Council's policy plan outlines the responsibilities for implementing policy 1-1. These include, but are not limited to: 1. Working with watershed management organizations (WMOs) and the MPCA on monitoring and managing nonpoint source pollution programs; and, 2. Evaluating the efforts of WMOs and local governments to control nonpoint source pollution and their impact on river water quality and effects on treatment plant effluent limits. (p. 10) The Council has also used its authority under the Metropolitan Land Planning Act of 1976 to review and comment on comprehensive plan amendments and environmental reviews to implement its policy on reducing nonpoint source pollution. These comments have generally focused on the need to reduce nonpoint source pollution and the possible tools that may be used to accomplish this task. 4 (0/. In addition to policy 1-1 of the Council's Water Resources Management Plan, Pan 1, the Council has two other policies addressing the environmental effects of nonpoint source pollution and water quality. The Council's Water Resources Management Plan, Part 3 states in policy 3-4 that: The Council, through its numerous review and approval authorities, will preserve all protected and unprotected natural watercourses--including associated wetlands, channels, floodplains and shorelands--to enhance water quantity and quality and to preserve their ecological functions (page 3-26); Policy 3-6 of the same policy plan states: The Council, in conducting its project approvals and reviews, will protect the utility of the region's water and related land resources and seek their restoration, where needed. Any action that threatens the viability of the water and related resource will be negatively reviewed (page 3-30). A related issue is the Minnesota River Basin extends beyond the Twin Cities Metropolitan Area. The Metropolitan Council has no planning or regulatory authority in Greater Minnesota. This makes it difficult for one governmental agency, such as the Metropolitan Council, to coordinate water quality planning activities in the Minnesota River Basin. The solution to nonpoint source pollution will require the involvement of all levels of government throughout the basin. The Metropolitan Council is committed to work with the Minnesota Pollution Control Agency, the Board of Water and Soil Resources and other state and regional agencies to ensure that appropriate steps are taken in Greater Minnesota to achieve the 40 percent reduction in nonpoint source pollution to the Minnesota River. PROPOSED INTERIM STRATEGY An interim strategy is needed to address both the nonpoint source pollution issue and to implement the Council's policy 1-1 of the Wastewater Treatment and Handling Policy Plan, Part 1, policies 3-4 and 3-6 of the Council's Water Resources Management Plan, Part 3 and the EPA and MPCA goal of 40 percent nonpoint source pollution reduction to the Minnesota River by 1996. The Council is committed to working with WMOs and local governments through the planning process outlined in Minnesota Statutes, section 103B.201. The Council also recognizes its responsibility to prepare and adopt a water resources plan pursuant to Minnesota Statutes, section 473.157. In the last year, Council staff has met with all of the WMO boards in the Minnesota River Basin to seek cooperation in achieving the EPA/MPCA 40 percent reduction goal. In addition, the Council staff has formed a technical advisory committee made up of local government officials and other interested parties to seek advise and disseminate information on nonpoint source pollution in the Minnesota River and its tributaries. However, it will take several years for the Council, WMOs' and local governments to prepare and implement the above referenced plans. In the interim, steps should be taken that allows local governments and WMOs to take immediate action to reduce the adverse impacts of nonpoint source pollution on area water. bodies, specifically on the Minnesota River. The following interim strategy is designed to make progress toward meeting the EPA and MPCA goal of 40 percent nonpoint source pollution reduction to the Minnesota River by 1996. This interim 5 . strategy is a minimum that the Council will accept as part of any local government comprehensive plan. It should be recognized by local governments that more comprehensive revisions to stormwater plans may be required once the Council and WMOs complete their planning under Minnesota Statutes, section 103B.201 and 473.157 in order to meet the EPA/MPCA 40 percent reduction goal for the Minnesota River. 1. Local governments in the Minnesota River Basin must adopt design standards for new stormwater ponds that will reduce the contaminant loadings from surface water runoff. One set of design criteria that is widely accepted is from the National Urban Runoff Program (NURP). Appendix A is attached and describes NURP designed pond performance standards. These criteria, or similar specifications which are equally effective, should be incorporated in the stormwater plan of every local government in the Minnesota River Basin. At the present time, this policy does not direct the retrofitting of existing stormwater ponds. 2. Local governments in the Minnesota River Basin must also include in their stormwater plans the MPCA's urban "best management practices," titled Protecting Water Quality in UrbanAreas or an equivalent set of standards. These standards are to be used for all new or redeveloped land development. These local governments must also notify their residents of the EPA/MPCA 40 percent reduction goal, "best management practices" to achieve this goal and available resources if additional information is needed. 3. All local governments in the Minnesota River Basin must adopt the Department of Natural Resources' shoreland regulations as found in the Statewide Standards for Management of Shoreland Areas as prescribed by the timeline in (Minnesota Regulations Parts 6120.2500 - 6120.3900) and consistent with the DNR's implementation strategy. Local governments should work with the DNR to determine the most effective way to implement the DNR's shoreland regulations. 4. All local governments in the Minnesota River Basin must adopt as part of their comprehensive plans and official controls the measures described in items 1 and 2 by September 30, 1992. Each local government should notify the affected Watershed Management Organizations of its intentions to comply with items 1 and 2. 5. After September 30, 1992, the Council may require modification of plan amendments that involve land use activities that would generate surface water runoff, unless the local government has adopted the interim measures described in items 1 through 3. The Council will not require a plan modification regarding nonpoint source pollution if a local government has adopted NURP standards and MPCA's "best management practices" by September 30, 1992, and is following the DNR's shoreland regulation implementation strategy. 6. The Metropolitan Council will continue to develop target pollution loads for all watersheds in the Twin Cities Metropolitan Area. 7. The Association of Metropolitan Municipalities will advise its member cities of the urgent need to implement runoff and land management practices that improve the quality of direct and indirect runoff discharges to the Minnesota River and of the consequences to the region of failing to meet the EPA/MPCA 40 percent reduction goal by 1996. 6 ~3. 8. The Metropolitan Council and the Association of Metropolitan Municipalities will work with State of Minnesota agencies to reduce nonpoint source pollution to area water bodies in Greater Minnesota. 9. The Metropolitan Council and the Association of Metropolitan Municipalities will monitor the effectiveness of the above-mentioned interim steps to address the nonpoint source pollution problem in the Minnesota River Basin. If sufficient progress has not been made by 1994 to reduce nonpoint source pollution to the Minnesota River, the Metropolitan Council and the Association of Metropolitan Municipalities will work to devise a solution designed to meet the EPA/MPCA goal of 40 percent reduction by 1996. G:\USER\ME1702S\REVISE-D:4.23.92 7 . ADVISORY PARKS, RECREATION & NATURAL RESOURCE COMMISSION DEPARTMENT HAPPENINGS AUGUST, 1992 EAA fall soccer and football schedules have been received. City facilities on which games and practices will occur are: Soccer: 3 fields at Ohmann Park, one field each at Rahn, Sky Hill, Quarry, Mueller Farm, and Bridle Ridge Parks. Eaa's use of the Northview Athletic soccer fields is limited to Sunday games. Three fields at Eagan High School will be used by the EAA soccer program. Bantam Soccer will use six (6) fields at Blue Cross/Blue Shield, three(3 at Rahn Athletic and one (1) at Rahn Park. EAA Football will play games at Goat Hill Park on one night a week. These fall activities are now underway and will continue to mid-October. 2.*<< NYSCA coaching clinics for EAA's basketball program will be held in mid-October. 3.*<< The Eagan Seniors group hosted the Rosemount Singers Kitchen Band. It was a fun afternoon. 4.*<< Several of the members of the Eagan Seniors Group have now moved into the Senior Housing Complex. Staff will be approaching management of the facility concerning holding some Seniors meetings at that facility. 5.*« Dakota Hills Middle School has submitted its schedule of fall sports to be held at Northview Athletic. The good news is that football practice space is no longer required to be provided at Northview. Daily use of the soccer fields for co- curricular games and practices is planned. Staff has not received the physical education unit calendar. This is an important piece of information for sharing with maintenance. 6.*< Staff are working on a report regarding facility use, design, construction and maintenance interaction between the department and ISD #196. The impetus for the report is a study by Community Education #196. At the present time, no one at the school district has the complete picture of how much cooperative effort exists with the city, nor the financial commitment the department makes toward community facilities. 7.*« A recent clarification regarding the requirement for pre-exposure Hepatitis B. vaccination for workers who administer first aid has come from the Minnesota Department of Labor and Industry. The vaccine need not be offered to workers who respond solely to injuries resulting from work place accidents. The Departments' seasonal employees fall into that category. In the event that vaccination is ever needed for a seasonal employee, the post-exposure vaccine is an acceptable alternative. 8.*<< Registration for fall recreation activities begins on September 12, 1992. The Discover Newsletter will be available in the community on Wednesday, September 9th. 9.*<< Work was completed on the new playground at Wescott Station Park in early August. This project was undertaken by Don Buecksler and Alex Lammers of the Parks and Operations Division. The new playground features a concrete approach ramp and transfer deck making the structure handicapped accessible under the new Federal ADA guidelines. 10.*- The Twin Cities Tree Trust installed a new perimeter at the playground id Ridgecliff Park. The original perimeter was installed in 1985 and no longer met federal safety standards for setback from the play elements. The new perimeter has greatly enhanced the amount of open space for play and improved the aesthetic value of the playground. 11.*< As their final project the Tree Trust also installed three park benches at Wescott Station Park. One of the benches lies within the wooded area overlooking a park pond. This bench required the installation of a timber retaining wall and erosion fabric. In addition, the Tree Trust assisted with the placement of surfacing material within the Wescott Station playground. 12.*< Two new park benches and two athletic field benches were installed at Captain Dodd Park in the month of August. This work was done by maintenance workers Alex Lammers and Paul Graham. It is anticipated that the next improvement to the park will be the installation of a children's play area with construction expected to begin on September 14th. 13.*<< New flag poles were installed at Rahn Athletic Park and at the high school baseball field adjacent to Northview Park. The flag poles were made available to the city through an anonymous donation from a local business. 14.*<< In late August construction was initiated on new dugouts at Rahn Athletic Park. The dugouts will be similar in design to those at Goat Hill Park. Park Maintenance employees Gary Skogstad and Scott Eppen will be taking a lead role in completing this project for the city. 15.*<< A new drinking fountain was installed on the shelter building at Goat Hill Park. This much needed addition will respond to the many requests of ball players and spectators to have a source of drinking water at the park. 16. *<< Sealcoating of the city's park and boulevard trails and parking lots was completed under a contract with Allied Blacktopping in August. Among the parks included in this year's contract were Thomas Lake, Carnelian, Kettle and O'Leary. In addition, about nine miles of boulevard and park trails were sealcoated using a tar emulsion and granite chip application. Before the sealcoating began staff of the Street Division cracksealed and patched areas of the trail that were in need of structural repair. This was the sixth consecutive year that the Parks and Recreation Department has been implementing it's long-range bituminous maintenance management program in parks. 17.*<< On Friday, August 14th, the Parks and Recreation Department played host to the annual Twin Cities Tree Trust Recognition Luncheon. In attendance were more than 100 youth employees from throughout the Dakota County area, local officials, and Tree Trust staff. This year's keynote speaker. was Lt. Governor Jonell Dyrstad. The event was held at the Trapp Farm Park facility and the weather was very favorable. 18.*<< With the early fall-like weather, staff got a jump on the fall fertilization program in late August. Once again, strictly low or no phosphorus fertilizer will be used on all of the city's parks and public building grounds to meet water quality goals. This work is being done by Alex Lammers and Paul Graham and will take approximately three weeks covering some 250 acres. 19.*<< Routine maintenance activities continued through the month of August. These included ballfield and pavilion set up and operations, athletic field striping, ball diamond dragging, continuation of all mowing routes, set up and striping of football and soccer fields and playground and tennis court inspections. A big word of thanks goes to all of our seasonal employees who have done an outstanding job this year in keeping on top of all the routine maintenance activities. 20.*<< The Dakota County Adult Sentencing to Service Program was back in Eagan parks during a portion of August. Their primary focus was on pruning boulevard and park trails and the removal of large sumac stands which are invading the Thomas Lake Park prairie. The STS crew also initiated some work on the clean up and remulching of shrubbery beds within the city's parks. This project will be completed when the STS program returns to the city on September 3rd for a three week period. It should also be noted that Ken Vraa and John VonDeLinde presented a plaque of appreciation to the Dakota County Board of Commissioners on August 4th recognizing cooperation and achievements of the STS program in Eagan parks. 21.*<< In late August the Forestry Division submitted two applications to the Department of Natural Resources under their Community Forestry Grants Program. The first grant proposal calls for an accelerated reforestation project (pilot project) in the Lexington Square subdivision utilizing a newly developed tree shelter/seedling growth technology (the same system being employed at the Patrick Eagan nursery). The second proposal calls for the landscaping of Blackhawk Park in the spring of 1993. If successful, the city must complete either of the projects no later than June 30, 1993. *City Council - September 2, 1992 <<Commission meeeting - August 6, 1992 CD~. SUBJECT: PRELIMINARY PLAT (DEERHAWK ADDITION) APPLICANT: DAKOTA COUNTY STATE BANK LOCATION: P.LD. #10.02000-011.75 (SE QUARTER SECTION 20) EXISTING ZONING: SINGLE FAMILY (R-1) DATE OF PUBLIC HEARING: AUGUST 2S, 1992 DATE OF REPORT: AUGUST 12,1992 COMPILED BY: COMMUNITY DEVELOPMENT DEPARTMENT. APPLICATION SUMMARY: An application has been submitted requesting a Preliminary Plat consisting of five single family lots on approximately 2.42 acres of R-1 (Single Family) zoned land. The City's Comprehensive Guide Plan designates this area D-ll (0-6 units/acre) which is consistent with both the present zoning and proposed use. The site is located at the southeast intersection of Blackhawk Road and Deerwood Drive. EXISTING CONDITIONS: The site contains a significant amount of mature vegetation, including many oaks. The topography ranges from gentle to severe slope and there is a wetland located in the northwest corner of the site. City trails are located along both Deerwood Drive and Blackhawk Road adjacent to this parcel. COMMENTS: According to the applicant, the bank has held the property for two years and is subdividing the 2.42 acre parcel into lots for individual ownership. At this time, custom home sites are proposed and no mass grading is proposed. The lots range in size from 12,000 sq. ft. to 26,265 sq. ft. and have a lot width of 85' or more. As proposed, all lots meet code requirements. Lots 1 and 2 will take access from Blackhawk Road, while Lots 3 through 5 will gain access from Deerwood Drive. Due to the size of right-of-way for Blackhawk Road and Deerwood Drive, a 40' front building setback would normally be required. r The applicant is proposing a front building setback of 30' which is consistent with existing building setbacks north of this plat along Deerwood Drive and existing homes fronting Blackhawk Road west of the site. The 30' setback is proposed to maximize tree preservation and limit excessive grading. City Code section 11.20, subd. B.I. allows new single family homes to maintain prevailing front building setbacks of existing homes in an established area. PARKS & RECREATION: Parks & Recreation staff will be recommending a cash parks dedication and a cash trails dedication to the Advisory, Parks, Recreation, and Natural Resources Commission at its September 3, 1992 meeting. X07. GRADING/DRAINAGE/EROSION CONTROL: A minimal amount of grading will be necessary to prepare Lots 1 & 5 for house construction. The preliminary grading plan shows grading on Lots 2, 3 & 4 to prepare those lots for house construction. The existing wetland on Lots 2 & 3 would be relocated to the west and the wetland would be redefined onto the north half of Lot 2. The maximum cuts on this site are proposed to be 10 feet, and the maximum fill is 4 feet. The drainage off of the frontyards of the lots will be directed to the adjoining streets. The drainage off of the backyards of the lots will be directed to the proposed wetland on Lot 2. The preliminary grading and drainage plan shows proposed storm sewer be constructed to drain the wetland to the existing storm sewer on Deerwood Drive. The houses abutting the wetland shall have a lowest entry level of elevation 889.0 to provide two feet of freeboard above the 100-year HWL that the wetland could flood to. The developer has sent a letter to the City asking if the City had any interest in purchasing property on this development for storm water ponding. The City is analyzing the existing storm sewer systems and ponds in this area to see if the location and economics are feasible for adding another pond to the City's stormwater management system. The developer will be responsible for installing and maintaining erosion control measures in accordance with the City's Erosion/Sediment Control Manual Standards. The site contains many mature trees. According to the preliminary grading, drainage and development plan, about half of the wooded area will remain in the undisturbed state even after the houses are added. WATER QUALITY: This development will be subject to a cash dedication requirement to meet water quality standards. The amount of the dedication is estimated at approximately $1,900. In addition, the developer will need to' delineate and meet State Wetland Conservation Act requirements for all wetlands on the development site. The delineations and impact analysis must be submitted for review to staff no later than Monday, August 23, 1992. Recommendations on both water quality mitigation and wetland protection are subject to approval by the Parks, Recreation, and Natural Resources Committee. UTILITIES: Adequate sanitary sewer of sufficient depth and capacity is readily available to the lots from an existing 9" sanitary sewer along the east side of Blackhawk Road or from an existing 9" sanitary sewer along the north side of Deerwood Drive. Adequate water main service of sufficient pressure and capacity has been provided from an existing 16" water main along the west side of Blackhawk Road and an existing 18" water main along the north side of Deerwood Drive. The preliminary utility plan shows connecting to the existing mainlines in Blackhawk Road and Deerwood Drive and stubbing services across the roads to the proposed lots. Individual sewer and water services will be provided to each lot for sewer and, water service. The developer will be responsible for repairing the streets at each of the service crossings. STkEETSIACCESSICIRCULATION: Street access to this development is available from Deerwood Drive on the north side and Blackhawk Road along the west side of the site. The development proposes to add three driveways out to Deerwood Drive and two driveways out to Blackhawk Road. No driveways will be allowed onto Taconite Trail until the existing driveway on Taconite Trail is improved to a City standard street with concrete curb and gutter and bituminous surfacing. The preliminary development plan does not show any driveway from the new lots to be added onto Taconite Trail. In the surrounding developments of Cedar Grove 7 and Cedar Grove 8, the houses abutting Deerwood Drive and Blackhawk Road have driveways that connect to the City streets. • As shown on the preliminary plat, 50 feet of h right-of-way shall be provided along the lots that abut Blackhawk Road and Deerwood Drive. The developer will be responsible for obtaining all the necessary permits from the affected agencies such as MPCA, MWCC, Dept. of Health, MN DNR, etc., prior to final plat approval. FININCIAL OBLIGATION - Deerhawk Addition II Based upon the study of the financial obligations collected in the past and the uses proposed for a property, the following charges are proposed. The charges are computed using the .Ci existing fee schedule and connections proposed to be made to the City's utility system base on the submitted plans. Impl+ovement Use Rate Quantity Amount Sto Sewer Trunk S.F. .069 S.F. 79,225 S.F. $ 5,467 Lateral Benefit S.F. 15.30 if 502 if 7681 Water ' Lateral Benefit S.F. 17.25 if 502 if 8,660.

LOCATION: SW 1/4 OF SECTION 31 EXISTING ZONING: AGRICULTURAL DATE OF PUBLIC HEARING: AUGUST 25, 1992 DATE OF REPORT: AUGUST 17, 1992 COMPILED BY: COMMUNITY DEVELOPMENT DEPARTMENT APPLICATION SUMMARY: An application has been submitted requesting a Rezoning of 5.2 acres from Agricultural to R-1 (Single Family) and a Preliminary Plat of 11 acres located in the SW 1/4 of Section 31. EXISTING CONDITIONS & LOCATION: The proposed plat is located west of Slater Road, south of Whispering Woods 4th, 5th and 6th additions, and north of unplatted Agriculturally-zoned property. The property to the west and north is zoned R-1 (Single Family) and the remaining property to the south and east is currently zoned Agricultural. The Land Use Guide Plan (March 1991) designates this area as D-1 (Single Family, 0-3 units/acre), the proposed 9th Addition is consistent with this designation. COMMENTS: The Preliminary Plat for Whispering Woods 4th Addition, 27.7 acres, was approved in 1988. Consecutive plats have followed since that time. Now that most of the ots are developed in those additions, it is the applicant's desire to plat 11 single family lots and one outlot on 5.2 acres as the 9th Addition. All lots meet, or exceed the 12,000 sq. ft. minimum lot area (the average being 13,740 sq. ft.), and the minimum 85' lot width. The applicant is requesting a 20' front yard setback Variance (50' to 30') along Slater Road for Lot 1, Block 1, Lot 1, Block 2, and Outlot A. Also requested is a 10' front yard setback Variance (30' to 20') for Lots 1-7, Block 3, and Lot 2, Block 2. Hilla, Inc. is requesting, these Variances due to the very rough terrain and to preserve trees in these lots. The total density for the project is 2.35 lots per acre which meets Code requirements of 0-3 units/acre. PARKS & RECREATION: The Advisory, Parks, Recreation, and Natural Resources Commission is recommending that the proposal be subject to a cash parks dedication and a cash trails dedication. lq- GRADING/DRAINAGE/EROSION/EROSION CONTROL: This 11-lot residential subdivision is in an area of rolling terrain that is heavily wooded. The developer has graded a rough road through the trees where the proposed street will be built. The preliminary grading plan submitted for review for the proposed 9th Addition shows cuts of 18 feet and fills of 14 feet. The grading for the lots and houses will remove a majority of the trees on this site. The drainage for this site will require the construction of catch basins and storm sewer at the low point of the street. The storm sewer line will be constructed in between Lots 3 and 4, Block 3, and discharge into city of Burnsville Pond E-24. Pond E-24 has an existing 21" outlet on the west end of the pond that drains the pond through Burnsville to the Minnesota River. The area of the pond at the normal water level is approximately 9.5 acres and the 100-year high water level is 939.1. The City of Burnsville purchased the area around Pond E-24 for ponding purposes. The grading of this development shall not disturb a 50 foot buffer zone along the edge of Pond E-24. The buffer zone shall allow the existing trees and vegetation around the pond to remain in the undisturbed state to help prevent erosion into the pond. Erosion has occurred into Pond E-24 in the backyard area of Lot 7, Block 3. This development will be responsible for removing the eroded sediments from the pond and the excavated materials shall be placed away from the pond. Erosion control measures shall be placed around the pond to prevent further erosion. The development will be responsible for installing and maintaining erosion control measures in accordance with the City's Erosion/Sediment Control Manual Standards. WATER DUALITY: This development will be subject to a cash dedication requirement to meet water quality standards. The amount of the cash dedication is estimated at approximately $4,100. In addition, several wetlands lie on the site. The developer is required to delineate each wetland and comply with provisions of the Wetland Conservation Act for each. Documentation must be submitted by Monday, August 24, 1992. Recommendations on both water quality mitigation and wetland protection are subject to approval by the Parks, Recreation and Natural Resource Committee. UTILITIES: Adequate sanitary sewer of sufficient depth and capacity is available in the' northeast corner of the site from an existing 8" line that flows easterly to the intersection of Slaters Road and Storland Road. The preliminary utility plan shows extending an 8" sanitary sewer in the street to the west to provide sewer services to the proposed lots. Adequate water main service of sufficient pressure and capacity is readily available at the intersection of Slaters Road and Storland Road. The existing 8" water main is proposed to be connected to in Slaters Road and the utility plan shows extending an 8" water main to the west in the proposed street to serve the proposed lots. S5. STREETS/ACCESS/CIRCULATION: Street access to this development is available from • the intersection of Slaters Road and Storland Road. The preliminary layout plan shows constructing a 34 foot wide street that will extend from Slaters Road to the west and provide a temporary cul-de-sac at the west edge of Lot 7, Block 3. With the platting of Lot 1, Block 4, a street stub shall also be provided to the south lot line of this lot. The driveway for Lot 1, Block 4, shall be directed to the main east west road along the north side of Lot 1, Block 4. The overall concept plan for this area shows that the east-west road through this site will be extended in the future to the west to Burnsville and connect in with the stubbed street of 125th Street. RIGHT-OF-WAY/EASEMENTS/PERMITS: The plat for this development shows a 60 foot wide right-of-way for the proposed east-west street. Also, an easement for the temporary cul-de-sac shall be provided. The final plat shall provide easements for Pond E-24 up to the high water level of the pond. The developer will be responsible for obtaining all the necessary permits from the affected agencies such as MPCA, MWCC, Dept. of Health, MN DNR, the city of Burnsville, etc., prior to final plat approval. FINANCIAL OBLIGATION - Whispering Woods 9th 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.

MANGINE LOCATION: OUTLOT A, OAK CLIFF 6TH ADDITION EXISTING ZONING: NB (NEIGHBORHOOD BUSINESS) PD (PLANNED DEVELOPMENT) DATE OF PUBLIC HEARING: AUGUST 2S, 1992 DATE OF REPORT: AUGUST 17, 1992 COMPILED BY: COMMUNITY DEVELOPMENT DEPARTMENT APPLICATION SUMMARY: Separate applications have been submitted requesting a Preliminary Plat of approximately two acres and two Conditional Use Permits to allow on- sale liquor, 3.2 beer or wine, and a pylon sign on Neighborhood Business zoned land within the Winkler-Jackson Planned Development. LOCATION/EXISTING CONDITIONS: The proposed Oak Cliff 7th addition is located in the southwest corner of Outlot,A, Oak Cliff 6th addition. The site is east of Mary, Mother of the Church, south of Cliff Road, west of Slater Road and the SuperAmerica located in the northeast corner of Oak Cliff 6th addition and north of Outlot B, Oak Cliff addition (zoned R-3 townhouse). PROPOSAL/SITE PLAN COMMENTS: The applicant, Brian Mangine, is proposing an 11,000 sq. ft. single story building for the purpose of a deli/banquet facility. The proposed 1,500 sq. ft. delicatessen located on the north end of the building is similar to Cossetta's general store in St. Paul where approximately 40' of counter space displays meats, cheeses, and hot and cold foods available for take-out only; there is no seating at the deli. A variety of imported Italian dry goods will be available. The 9,500 sq. ft. banquet facility can accommodate up to 450 persons. The hall has a room divider to accommodate two groups at one time. During the week it is intended that smaller break out rooms be used for business meetings, providing the latest in audio visual and special lighting needs. The exterior finish of the building is a split face block matching the SuperAmerica in a sand/creme color; approximately 16' up on the 22' high building, a ribbon of complimentary color will accent the building. The entrances to the building will be further enhanced with a reddish-brown brick (same as SuperAmerica), as well as the vestibule area.' The building, as proposed, meets all Neighborhood Business setback and lot coverage requirements. The site plan indicates four ingress/egress points, two on the north and two to the east. One hundred twenty-four parking stalls have been provided on-site. There are no specific parking provisions referenced in the City Code for a banquet facility. Cross-parking easements were approved with the 6th addition plat. The landscape plan indicates a variety of understory and overstory deciduous trees and evergreens, combined will provide year-round color to the site and screening to the south. The applicant is proposing a 3'-4' berm along the south property line to eliminate car headlights. A Conditional Use Permit for liquor and 3.2 beer or wine has been applied for at this site. The applicant has applied through the proper licensing applications and is pending approval. A pylon sign is being proposed to be located on the east side of the northeast entrance and the proposed sign meets the 27' height and 125 sq. ft. per side code allowances. PARKS & RECREATION: Recommendations of the Advisory Parks, Recreation, and Natural Resources Commission are as follows: 1. The parcel is located within the Winkler-Jackson Planned Development. The parks dedication has been fulfilled via a land dedication of Slater Acres Park. 2. The Planned Development required the developer to install trailway, therefore the application is not responsible for a trails dedication. GRADING/DRAINAGE/EROSION CONTROL: The proposed development has been graded by the Oak Cliff 6th Addition development. The preliminary grading, drainage and erosion control plan submitted with this application shows a minimal amount of grading will be necessary to prepare the building and parking lot for construction. The drainage from the site will be directed in two directions. The north half of the parking lot will drain to an existing 12" storm sewer that runs along the north property line in an easterly direction towards Slater Road. The south half of the parking lot will drain to an existing 15" storm sewer line that also drains in an easterly direction toward Slater Road. Both of the existing storm sewer lines have sufficient capacity to serve this development and both lines drain across Slater Road to Pond AP-10B. An outlet has been provided for Pond AP-10B to Pond AP-10, which is a designated ponding area in the City's Comprehensive Storm Water Management Plan. The proposed development will be responsible for constructing catch basins at the low point of the parking lot to convey stormwater runoff to the existing storm sewer lines. The development will be responsible for installing and maintaining erosion control measures in accordance with the City's Erosion/Sediment Control Manual standards. Pond AP-10A which is located along the west edge of the site shall be protected from erosion of sediments into the pond from this site. Also, the wooded area south of this development shall be protected from erosion into the trees. WATER QUALITY: The proposed two acre commercial development is located in drainage basin A in southwest Eagan. The parcel is part of a sub-drainage that discharges to Pond AP-10 which is a shallow three acre natural pond classified as a nutrient trap in the City's Water Quality Management Plan. The Oak Cliff 6th Addition development constructed off- site ponding to meet the City's water quality management standards so no additional water quality provisions will be required of this plat. Pond AP-10B has been constructed along the east side of Slaters Road. Pond AP-10B has a surface area of 0.47 acres at the normal water level and a wet storage volume of 1.8 acre feet. In addition, no wetlands subject to Wetlands Conservation Act jurisdiction lie on the site. Recommendations on both water quality protection and wetlands protection are subject to approval by the Parks, Recreation, and Natural Resources Commission. UTILITIES: Sanitary sewer of sufficient size, capacity and depth is readily available and has been stubbed to this development by the Oak Cliff 6th Addition development, City Project #627. Sanitary sewer service to the building will be provided by connecting to an existing 6" sewer service stub at the north property line of the lot and extending the 6" sewer service to the proposed building. A manhole will be required over the sewer service at the south edge of the City's public utility easement. Watermain of sufficient size, pressure and capacity is readily available to serve this development from an existing 8" watermain that has been constructed along the north property line of the lot by Oak Cliff 6th Addition, City Project #627. Water service to the building will be provided by connecting to the existing hydrant and relocating the hydrant to an island in the proposed parking lot and then extending the 6" line up to the building. The hydrant shall be located in a position that provides adequate fire protection to the site. STREETS/ACCESS/CIRCULATION: The preliminary site plan proposes access to this site by extending the private street that is along the south side of the Super America site in Oak Cliff 6th Addition. The Oak Cliff 7th Addition development will be responsible for constructing the private street from the Super America site to the west property line of Oak Cliff 7th. The church parking lot to the west proposes to have access to this private street and connect their parking lot to the private street. City staff is recommending that the private street that heads in a north-south direction up to Cliff Road shall also be constructed from Cliff Road down to the Oak Cliff 7th Addition. The north-south private street at the connection to Cliff Road will be a right-in access only. Under Dakota County Project #32-31, the County will be extending the median on Cliff Road to a point 260' west of the west property line of this plat. The median extension will allow this development to construct a driveway out to Cliff Road. The private street system in the Oak Cliff 6th and 7th Additions shall be constructed with concrete curb and gutter to provide drainage to the storm sewer system and to confine the parking to the paved areas. The preliminary site plan for Oak Cliff 7th shows two driveway openings connecting to the private street system that runs along the north lot line. The driveway openings shall be at least a 30' wide opening. EASEMENTS/RIGHT-OF•WAY/PERMITS: This development shall provide cross- easements over the private street system. This development shall dedicate a 20' drainage and utility easement centered over the existing storm sewer line that runs along the south. property line of the site. Also, the existing 8" sanitary sewer and 8" watermains that run along the north property line shall have adequate drainage and utility easements dedicated over the lines. This development will be responsible for insuring that all regulatory agency permits (MPCA, Minnesota Department of Health, MWCC, Dakota County, etc.) are obtained prior to final plat approval. FINANCIAL OBLIGATION - Oak Cliff 7th Based upon the study of the financial obligations collected in the past and the uses proposed for the property, the following charges are proposed.

COMMUNITY DEVELOPMENT DEPARTMENT APPLICATION SUMMARY: Separate applications have been submitted requesting a Rezoning of approximately 40 acres zoned Agriculture to PD (Planned Development) and a Preliminary Plat of 181 units located north of Diffley Road in the SE 1/4 of Section 21. LOCATION: The site is located north along Diffley Road (County Road 30), south of Deerwood Elementary School and the new middle school, west of Knob Hill Townhomes and Deerwood Ponds addition, and east of the Bieter Company property. The surrounding zoning districts of this site are as follows: Public Facilities to the north, Planned Development Single Family and Townhouse to the east, Park and Planned Development townhouse across Diffley Road to the south, and Agriculture to the west. The March 1991 Comprehensive Land Use Guide Plan designates this 40 acres as D-II, Mixed Residential (0-6 units/acre). EXISTING CONDITIONS: Currently there is one home located near the southeast comer of the property that will be removed as a result of this project. West of this home is a pond surrounded by a mixture of mature deciduous trees extending as far south as Diffley Road. West of the pond is a gently-rolling open grassy site. The existing homestead takes its access from Diffley Road. PROPOSAL: Wensmann Realty is proposing a mixture of residential uses. The scope of the project is as follows: 18 single family lots, 14 duplex lots, 35 townhome units, and 114 cluster homes, for a total of 181 units. The density of the entire phasing project is 4.77 units/acre. Access to the site is from Diffley Road and from Cashell Glen Road (formerly Knob Lane). A pathway to the school property has been included in this plat. It is located in the extreme northeast corner between Lot 9, Block 3, and Lot 3, Block 3, Deerwood Ponds addition. It is the recommendation of staff that another path be developed along the west property line of Lot 1, Block 3, and the northernmost deck homes. This would allow access for the western portion of the site. It is the intention of the developer to phase this project. • The 18 single family lots are located on the north side of the site with nine lots backing up to the school property and nine lots opposite` those across Cashell Glen Road coming into the site from Deerwood Ponds addition to the east. These lots range from 12,300 sq. ft. to 22,200 sq. ft. with an average of 15,555 sq. ft. Total density for the R-1 portion of the Planned Development is 2.8 units/acre. All lots meet, or exceed the minimum lot area and lot width. The duplex lots are located along the proposed north/south public street on the east and west of the existing pond. The proposed 14 lots range in size from 9,100 sq. ft. to 16,500 sq. ft. with an average lot size of 12,335 sq. ft. Density for the R-2 area of the Planned Development is 3.5 units/acre. The applicant is requesting a Variance of 10' to the required 30' front yard setback for Lot 14, Block 5. The remaining 13 units meet the 30' setback requirement. The twin homes, as proposed, are 3/5 units brick and rough cedar sided with a three or four season porch. Each unit is 1,400 sq. ft. with an expandable lower level. The driveways will be blacktop and all yards will have an underground sprinkler system. Prices will range from- $160,000 - $200,000. A homeowners' association will be established. The townhomes consist of four to six units per building. The density for this townhome (R- 3) portion of the Planned Development is 3.36 units/acre. The one or two story units are owner-occupied and are approximately 1,400 sq. ft. finished with a three or four season porch as an option. Each unit will have a double garage, concrete driveway, and underground sprinkler system. The units are 3/5 brick units with rough cedar siding and vary in price from $130,000 - $180,000. A homeowners' association will be established. The 35 units will take access from a private cul-de-sac. As proposed, all units meet the 20' building setback allowed on a private dead end street. The townhomes are located on the east side of the pond, Eighteen additional guest parking spaces have been provided along the private cul-de-sac. The 114-unit cluster homes are located west of the north/south public street and are served by private loop streets. The buildings range from eight to twelve units per building. The proposed layout shows setbacks along the private streets of 20'. Wensmann Homes, Inc. markets these as "deck homes". They include 1,144 finished square feet and a two-car garage. The exterior is brick with aluminum fascia and soffits. All have a blacktop driveway and underground sprinkler system. The cluster homes will be owner-occupied and belong to a condominium association. Prices will range from $62,000 - $80,000. Seventy-six additional guest parking stalls have been provided throughout the cluster development. As proposed, the multi-family buildings (R-2, R-3, and R-4) meet the standards as set forth in Subd. 6H. Exterior Building Finish - which state that at least 50% of any exterior finish shall consist of a combination of materials which are non-combustible, non-degradable, and maintenance-free. The landscape plan shows a good mixture of overstory and understory deciduous trees, as well as evergreens. The applicant is preserving some of the existing vegetation around the pond which includes many mature trees. /XU PARKS & RECREATION: The Advisory Parks, Recreation, and Natural Resources Commission will be reviewing the Wenzel Addition at their September 3rd meeting. Staff's preliminary recommendations are for both a cash parks and trails dedication. The developer shall also be responsible for grading a 5' wide sidewalk pad within the northeast corridor to Deerwood School. Staff has contacted the school district and appears that a mutual effort with the Wenzel Addition will result in a contiguous trail corridor between these adjacent parcels. The multiple areas within the Wenzel Addition are responsible in providing recreation open space. Staff's preliminary recommendation is for the revision of grades within several areas providing for a flat recreation open space. GRADINGIDRAINAGE AND EROSION CONTROL: The 30 acre site contains a mixture of open fields and wooded areas and a 2 acre pond (Pond BP-4) located in the center of the site. The preliminary grading plan shows that a majority of the site will be disturbed by the grading that will be required for the houses and streets. However, the existing trees around Pond BP-4 are proposed to be saved and also a row of trees along the north property line are shown to be saved. The grading for the site will require a maximum cut of 18' and a maximum fill of 12'. A small amount of grading will occur off the site beyond the northwest comer of the site on the Deerwood Middle School Addition development. Any existing wells or septic systems on this site shall be abandoned prior to the grading of this site according to City and Dakota County requirements. Locations of the wells and septic systems shall be shown on the final grading plan. The drainage from this site will be directed to Pond BP-4 which is a pond of the City's Stormwater Management Plan. In addition to the direct drainage of approximately 70 acres that drains to BP-4 an additional 3,700 acres drains to the pond. On the south end of BP-4 is a 42" storm sewer line with an invert elevation of 868.3 that drains into the pond. There is also a 36" line that drains Diffley Road that discharges into the south end of the pond. The City currently has an outlet for Pond BP-4 with a controlled elevation at 874.2. Because of the nearly 6 foot difference in elevations of the outlet compared to the invert of the 42" line entering the pond, the City is studying how to revise the storm sewer in this area to lower the normal water level of the pond to closer match the invert elevation of the 42" line. By lowering the normal water level of Pond BP-4, it would allow the 42" line to drain more effectively into the pond and eliminate some maintenance problems that the City is now incurring. The grading and drainage plan shall include a storm sewer line along the east/west public street to the west property line of this site. The storm sewer line is needed to provide drainage for an 8.3 acre area of future development west of this site. The development will be responsible for instaling and maintaining erosion control measures in accordance with the City's Erosion/Sediment Control Manual Standards. ' Pond BP-4 and the trees around the pond shall be protected from erosion of sediments. WATER DUALITY: This development lies in Drainage Basin B a short distance up- drainage of Blackhawk Lake, a Class I water body designated to support direct contact recreation. Runoff from the proposed development will eventually reach Blackhawk Lake and, if not treated, would degrade its quality. As such, this development will be subject to a ponding requirement to meet the City's water quality standards. In addition, there exist several wetlands on-site. The developer will be required to delineate these wetlands and comply with the Wetlands Conservation Act for each. Documentation for staff review on wetlands impacts should be submitted by Monday, August 24, 1992. Recommendations on both water quality mitigation and wetlands protection are subject to approval by the Parks, Recreation and Natural Resources Commission. //a. UTILITIES: Sanitary sewer service is available to serve this site from an 8" line on Diffley Road or from an existing 27" trunk sewer on the east side of the property. The preliminary utility plan shows connecting to the 8" line on Diffley at the public street connection opposite Heine Court. Also, a connection is shown to the 27" line in two locations. One location is to serve the private street area in the southeast comer of the site and another location is in the northeast comer of the site at the intersection of Cashell Glen in the Deerwood Ponds Addition. As shown on the preliminary utility plan, sanitary sewer shall be stubbed to the west property line in the east/west public street to serve the future development of property to the west of this site. Watermain of sufficient size, pressure and capacity is readily available to serve this development from an existing 12" watermain on Diffley Road from an existing 6" watermain along the east property line in the development of Knob Hill of Eagan from a 6" watermain in Cashell Glen, and from an 8" watermain in the Deerwood Elementary School site. The watermain layout shall includes a looping system fed by the City's Intermediate Pressure Zone watermains. As shown on the preliminary utility plans, the watermain layout shall include an 8" stub in the northeast comer of the site that will connect to the existing 8" watermain provided by the Deerwood Elementary School. The sanitary sewer and watermain services to the cluster housing unit buildings shall be a 6" PVC sewer line and a 6" DIP watermain. This layout will eliminate the need for individual sewer and water services to be provided to each unit in the cluster building. The single family, double family and townhouse units are proposed to have individual 4" sanitary sewer and 1" copper water services provided to each unit. STREETS/ACCESS/CIRCULATION: Access to this site is proposed in two locations. The site plan shows connecting to Diffley Road (Dakota County Road 30) opposite Heine Court with a public street that will run in a northerly direction. The preliminary site plan also shows connecting to Cashell Glen which is a street in the Deerwood Ponds development in the northeast portion of the site. The extension of Cashell Glen would be an east/west public street through this development that would end in a temporary cul-de-sac on the west property line. The north/south public street from Diffley Road up to the east/west public street shall be a 36' wide street. The east/west street from Cashell Glen to the west property line shall be a 32' wide street. The preliminary site plan also shows a private street that will loop through the southeast comer of the site to serve the proposed townhouse units. The preliminary site plan also shows a series of private streets that will be provided to serve the cluster . housing buildings. The private streets shall be designed according to the City standards with bituminous surfacing and concrete curb and gutter. EASEMENTS/RIGHT-OF-WAY/PERMITS: The final plat shall dedicate a permanent drainage and utility easement over Pond BP-4 up to its high water level. The sanitary sewer and watermains that will be provided to serve the cluster housing units and townhouse units in the private street areas shall have permanent drainage and utility easements dedicated over the main lines. A temporary easement shall be obtained by the developer over the temporary cul-de-sac along the west property line of the site. The east/west public street and the north/south public street shall have 60' of right-of-way dedicated over the streets. //3. The development will be responsible for ensuring that all regulatory agency permits (MPCA, Minnesota Department of Health, MWCC, Minnesota DNR, Dakota County Highway Department, Corps of Engineers, etc.) are obtained prior to final plat approval. FINANCIAL OBLIGATION - Wenzel 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.
