08/06/1992 - Advisory Parks & Recreation Commission MEMORANDUM TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: KEN VRAA, DIRECTOR OF PARKS AND RECREATION DATE: AUGUST 4, 1992 RE: AUGUST 6, 1992 COMMISSION MEETING The Advisory Commission will meet at 6:30 p.m. at the Municipal Center for a tour of Sky Hill Park, Blackhawk Park and also to review the portable trailer used for a warming house which is currently stored at the maintenance facility. We will return to the Municipal Center at 7:30 p.m. for our regular meeting. The department has an extremely light agenda for the month of August and barring any last minute additions to the agenda, you should be able to count on an early adjournment. There are three items under the Consent Agenda which staff has prepared a brief memorandum on. There are no development proposals and only one item under Old Business, which is the ADA standards update. Staff has, prepared a brief memorandum on this update and the impact on the park system. There are no other items on the agenda for the Commission other than Other Business and Reports. As always, if members are unable to attend the meeting we appreciate knowing of your absence in advance by calling the office.

Adjournment REMINDER: THE RECREATION SUB-COMMffTEE WILL MEET IMMEDIATELY FOLLOWING THE REGULAR COMMISSION MEETING Subject to Approval MINUTES OF A REGULAR MELTING OF ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION EAGAN, MINNESOTA JULY 2, 1992 Because there was not a quorum, the regular meeting of the Parks, Recreation and Natural Resources Commission was not held. Commission Members Knight, Widem and Ipsen were present for the meeting. Commission Members not present included Ted Billy, Deborah Johnson, Lee Markell and Jack Johnson. Not being able to conduct business, Jonathan Widem suggested that staff schedule another meeting date and notify the Commission Members so that recommendations could be made to the City Council in a timely fashion. Director Vraa confirmed that another meeting date would be scheduled and Commission Members would be advised of that meeting date. S- Subject to Approval MINUTES OF A REGULAR MEETING OF ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION EAGAN, MINNESOTA JULY 16, 1992 A regular meeting of the Advisory Parks, Recreation and Natural Resources Commission was called to order at 7:00 p.m. on Thursday, July 16, 1992 with the following Commission Members present: Jonathan Widem, Erin Ipsen, Lee Markell, Dan Mooradian, Kevin Knight and Jack Johnson. Commission Members Deborah Johnson and Ted Billy were not present. Staff present included Ken Vraa, Director of Parks and Recreation; Stephen Sullivan, Landscape Architect/Park Planner; Dorothy Peterson, Superintendent of Recreation; John VonDeLinde, Parks Superintendent; Rich Brasch, Water Resources Coordinator; Dave Running, Intern and Cherryl Mesko, Secretary. AGENDA Director Vraa asked that "Wetlands Task Force" be added as Item 2 under Water Quality. Dan Mooradian moved, Erin Ipsen seconded with all members voting in favor to accept the agenda as amended. MINUTES OF REGULAR MEETING OF JUNE 4, 1992 Kevin Knight moved, Dan Mooradian seconded with all members voting in favor to accept the minutes as presented. MEGHAN'S ADDITION - PULSAR, INC. Stephen Sullivan reviewed this item with the Commission noting that the current proposal has been revised since the Commission reviewed this parcel at the March 5, 1992 meeting. It was noted that staff has been unable to complete a comprehensive evaluation of the proposal since the information provided to the City to date has been incomplete. This issue will be brought back before the Commission as the necessary information is received from the developer. Water Quality Coordinator Brasch explained that Public Works feels there may be a problem with storm water run-off; if the run-off goes directly to Cedar Pond there may be a need for additional ponding. Rich noted that to date he has not seen the storm water layout for this site. Director Vraa added that this development appears to be close to final submittal based on staff's review of some unresolved issues. It's anticipated this item may be back to the Commission in August as the developer would like to begin work yet this fall. HAWTHORNE WOODS WEST - LYMAN DEVELOPMENT CO. Landscape Architect/Parks Planner Sullivan introduced this item as an application requesting the rezoning of 9.2 acres to R-1 single family and the preliminary platting of 12 lots. The site is located east of Dodd Road and south of Diffley Road adjacent to the Hawthorne Woods Addition. He continued that Lakeside and South Oak Parks serve this development therefore a cash dedication is being recommended along with a cash trails dedication. Rich Brash reviewed the water quality issues regarding this site noting that the run-off will discharge to Pond JP-68, a 3.4 acre wetland classified as a protected water by the DNR. The DNR has established a high water level for this wetland therefore no fill or excavation can occur within that area. '7. ADVISORY PARKS, RECREATION AND NATURAL RESOURCE COMMISSION MINUTES OF RESCHEDULED MEETING OF JULY 16, 1992 PAGE 2 Rich recommended that approximately 4 acres of the 9.2 acre site (including virtually all paved areas in the development) are proposed to drain to JP-68 and should be treated prior to discharge to protect the water quality of the pond. The remainder of the site drains overland to off-site areas to the north and east of the development and cannot easily be directed to the treatment pond nor will it drain to a recreational water body, therefore a cash dedication would be acceptable for that portion of the site. After further discussion, Kevin Knight moved, Jonathan Widem seconded with all member voting in favor to make the following recommendations to the City Council regarding parks and trails dedication for Hawthorne Woods West Addition. 1. The plat be subject to a cash parks dedication. 2. The plat be subject to a cash trails dedication. 3. The developer shall provide for staff approval a tree protection plan prior to final plat. This plan shall identify significant trees and tree masses. The plan should also show the proposed location of tree protection fencing. Kevin Knight moved, Erin Ipsen seconded with all members voting in favor to make the following recommendations to the City Council regarding water quality dedication for Hawthorne Woods West Addition. 1. The developer construct a small nutrient detention basin on-site to treat run-off from ponded areas within the development. The pond should have a surface area of at least .15 acre and a volume of at least .38 acre-feet will be needed to adequately treat this run-off. A larger pond would provide for greater removal of pollutants and could reduce commensurately the cash dedication associated with the remainder of the site. This on-site pond will treat run-off from paved areas of the development prior to discharge to Pond JP-68. 2. The treatment obligation for the remainder of the site is to be a cash dedication. 3. The pond design must be approved by City staff and the developer is strongly encouraged to leave undisturbed riparian vegetation within the wetland boundaries of Pond-68 as determined using the Corps of Engineers Wetlands Delineation Manual. PARK SHELTER BUILDING - REPLACEMENT NEEDS Director Vraa introduced this item and brought the Commission's attention to the background report in the packet reviewing the status of warming houses at Woodhaven and Lexington Parks. Ken continued that the warming houses provided at these sites are beginning to deteriorate and the Commission will need to take a look at how they want to deal with this issue. One option might be to remove the buildings because of their condition and another could be to look at replacement. After reviewing the history of the sites Director Vraa suggested that the Commission look at the future use of each site and the facilities that are provided. Some of the priority issues include the deteriorating condition of the temporary warming houses at Woodhaven and Lexington Parks; the condition of the Woodhaven rink which requires notice and an action plan and the design of Woodhaven and Lexington Parks should be considered in light of the Parks Master Plan and the Commission's vision of the community's need for facilities within these neighborhood parks five to ten years from now. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF RESCHEDULED MEETING OF JULY 16, 1992 PAGE 3 Lee Markell asked what the downside would be in waiting 1-2 years before making any changes to the existing buildings. Director Vraa explained that the existing buildings are more expensive to heat since they use propane and there is the concern for vandalism but those would be the only downside issues for not taking any action for a period of time. Kevin Knight asked if there was a trend in use patterns at these two parks to better help determine facility needs. Dorothy Peterson indicated that there were no reasonable means to determine that information because the use levels at park sites varies depending upon the neighborhood population and changes that occur in that respect. Jonathan Widem asked if there was a concern for safety in respect to these buildings. John VonDeLinde responded that the risk management company has addressed the use of propane and the electrical wiring coming off the pole to the building as potential problem areas. John also stated that the skating rink at Woodhaven is built into the hill and is nearing the end of it's life expectancy. He suggested that if Woodhaven will continue to be a skating site the condition of the rink needs to be addressed as well. Lee Markel] asked what staff's feelings were regarding the best solution for these sites. Director Vraa responded that there were mixed feelings among staff based on each of their perspectives. For example, the removal of Lexington as a skating site may create a hardship for this area which is isolated from other areas. Ken asked that the Commission take a look at both short term and long term options regarding these sites. Some of the alternatives the Commission may consider include renting or purchasing a trailer for the sites, construct a shelter building similar to those at Carnelian and Clearwater or do nothing and eliminate the building and rink at these sites. Kevin Knight asked if there were dollars in the budget to provide for either a trailer facility or a new shelter building or to do sufficient repairs to the existing buildings to allow them to be usable longer. Ken Vraa responded that there are not dollars allocated for significant repairs, only for emergency repairs, however if the Commission is looking at building a building, leasing or purchasing a trailer that would be an item that would need to be submitted for the 1993 budget as soon as possible. Dan Mooradian stated he would not be inclined to close sites. Kevin Knight agreed since Lexington is a very remote site but preferred doing some repair to the facilities to help get through the year. As a point of reference John VonDeLinde explained that an 8' x 24' trailer cost approximately $8,000 to purchase and has an 8 year payback; the cost of a permanent structure like that at Clearwater Park would cost approximately $12,000 and like the one at Carnelian, approximately $20-22,000. Stephen Sullivan added that this is the beginning of a trend the Commission will be needing to address on a regular basis; the changes and replacement that will need to occur at existing parks rather than the construction of new parks. Erin Ipsen noted that in purchasing a trailer there would be the potential for year-round use rather than renting a trailer for the three months needed for the skating season. Also, if the Commission is looking at purchasing, renting or building a building this needs to be budgeted for now. Jack Johnson stated he was not in favor of purchasing a permanent structure at this time but would rather see rentals occur this season and re-visit the issue in a year. Dan Mooradian agreed with renting at Lexington this year and re-visiting next year. Jonathan Widem suggested that if a trailer were purchased for Woodhaven ($8,000) and a rental trailer was planned for Lexington for the 1992/93 and 1993/94 seasons ($800 each season) than $10,000 would need to be budgeted now to accommodate those needs. q ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF RESCHEDULED MEETING OF JULY 16, 1992 PAGE 4 After further discussion, Jonathan Widem moved that $10,000 be budgeted for the purchase of a trailer at Woodhaven Park and trailer rental for two years at Lexington Park. Jack Johnson amended the motion to include the maximum rental time for Lexington Park would be 2 years and also recommended that the hockey/skating rinks at Lexington and Woodhaven Parks be maintained for a minimum of two years based on supporting survey information of users. This item will be reviewed again in one year. Lee Markell seconded the motion with all member voting in favor. LAWN SOIL TESTING PROPOSAL Water Resources Coordinator Brasch explained that staff is developing a proposal with Nick Slader, a Life Scout in Boy Scout Troop 510 in Eagan, to sample the nutrient content of soils in 150-200 residential and commercial yards. Nick wants to use this project to fulfill requirements for a service project to achieve the rank of Eagle Scout. Rich noted that the active promOtion by the City of no-phosphorus fertilizer use by residents and businesses will be helped if there was data that indicated that turf health would not be compromised by the use of no-phosphorus fertilizer to reduce phosphorus loading to lakes. The objective of this effort is to obtain information on the phosphorus content of lawn soils representative of the entire community. The cost involved for the sample analyses by the University Soils Testing Laboratory is approximately $1,000 - $4,000 and it is anticipated that the City would pay those costs. Jack Johnson commented that the dollars expended would be worth the information received that can be very helpful in the future. Kevin Knight asked if there was any way the University could negotiate a better rate for these test results or to see if these results could be of benefit to someone else, thereby reducing the cost. In response to a question Rich Brasch stated that the test sites have been located and will be done on private properties. Jonathan Widem sugyested that someone should check with some of the no-phosphorus fertilizer manufacturers to see if they would be interested in offsetting some of the costs for testing. Lee Markell indicated he would like to see the dollars spent if financial support cannot be obtained but wondered if there was a way to make this testing procedure more visual, i.e. improvement in water quality at a specific park. Rich Brasch stated he didn't know if it was possible to show this kind of improvement visually. Steve Sullivan suggested a signing option such as "Phosphorus Reduction Area". After further discussion, Lee Markell moved, Jonathan Widem seconded the motion to proceed with the soil nutrient testing project and expend the $1,000 - 1,400 that may be necessary for sample analyses by the University Soils Testing Laboratory. All members voted in favor. WETLANDS TASK FORCE Rich Brasch suggested it would be appropriate for the Water Quality Task Force to resume their meetings to set City Policy in determining criteria for developments in avoidance vs. replacement issues as they relate to wetlands on their sites. Rich envisioned the Task Force would begin meeting in late August/early September so that policies are in place when development starts in the spring. Based on the strong interest shown by most Commission Members, it was determined that the Task Force would be open to all Commission Members interested in attending. Rich Brasch stated he would provide background information before the first meeting and would establish a meeting date for the Water Quality Task Force at the August meeting. 4 ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF RESCHEDULED MEETING OF JULY 16, 1992 PAGE 5 DEPARTMENT HAPPENINGS Some of the Department Happenings highlighted included the number of registrations for summer programs (5500 to date), the construction at Deerwood Elementary resulting in having to transfer programs to Oak Ridge Elementary, planning for fall programming will begin in August, the successful Evening in the Park series, the long-term problem with oak wilt that will need to be addressed, the construction of Trapp Farm playground is nearing completion, the County's Adult Sentencing-to-Service Program has completed many projects throughout the park system and the Parks Department acquired a second Toro high capacity mower that has greatly improved the efficiency of the overall mowing operation. ROUND TABLE Lee Markell thanked staff for the early reports sent to the Commission Members and asked for an update on Blackhawk Park. Steve Sullivan responded that the bid time frame has been set, the park has been designed, will need more definition but will be go out for bid shortly. Jack Johnson asked for an update on the Caponi Art Park. Director Vraa responded that the City Council has agreed to do a tunnel to tie the art park to Patrick Eagan Park. Mr. Caponi has requested that a retaining wall be installed, however the City will not be able to absorb those costs and the County does need the City's approval before incorporating a wall within their expansion plans. The retaining wall issue will be reviewed by the City Council at their next meeting. Jack Johnson asked what the timing of this project -would be and Mr. Vraa responded that the county has decided not to proceed with the construction of Co. Rd. 30 this year therefore the exact timing is unknown at this time. Jack Johnson added that he would like to see the Commission take an active role in establishing a community event that can hopefully be continued on an annual basis. Director Vraa noted that BarbaraSellars from the department would be leaving the department effective July 31 for a move to Phoenix. With no further business to conduct, Lee Markell moved, Jonathan Widem seconded with all members voting in favor to adjourn the meeting. The meeting was adjourned at 9:35 p.m. Secretary Date MEMORANDUM TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: STEPHEN SULLIVAN, LANDSCAPE ARCHITECT/PARKS PLANNER DATE: AUGUST 3,1992 RE: CONSENT ITEMS 1. BUR OAK HILLS 3RD ADDITION - SHAMROCK DEVELOPMENT A Preliminary Plat consisting of two lots on approximately 2.6 previously-zoned R-1 (Single Family) acres located along Rolling Hills Drive in the NE 1/4 of Section 12. Recommendation: - The plat be subject to a cash parks dedication. - The plat be subject to a cash trails dedication. 2. WILSON ADDITION - MARY ANN WILSON A Preliminary Plat consisting of four lots on approximately 4.6 previously-zoned R-1 (Single Family) acres located along the west side of Blackhawk Road in the east 1/2 of Section 17. Recommendation: - Lots 2, 3 and 4 be subject to a cash parks dedication. - Lots 2, 3 and 4 be subject to a cash trails dedication. 3. ST. THOMAS BECKET ADDITION - ST. THOMAS BECKET CHURCH A Comprehensive Guide Plan Amendment from D-I (Single Family Residential) and D-II (Mixed Residential), a Rezoning from AG (Agricultural) to FP (Public Facility), and a Preliminary Plat consisting of approximately 33.1 acres for a church located along the west side of highway 3 south of Diffley Road in the SE 1/4 of Section 25. Recommendation: - The plat be subject to a cash trails dedication. - The parcel be subject to a cash parks dedication with any future change in zoning other than Public Facilities SS/nh /3. MEMO TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: RICH BRASCH, WATER RESOURCES COORDINATOR DATE: JULY 20, 1992 SUBJECT': WATER QUALITY REQUIREMENTS FOR WILSON ADDITION-MARY ANN WILSON (CONSENT AGENDA ITEM) PROPOSAL This preliminary plat application is for a single-family residential development consisting of 4 lots on approximately 4.63 acres located on Blackhawk Road in the east one half of section 17 (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 in its Water Quality Management Plan. WATER DUALITY ANALYSIS This development is located in Drainage Basin A northwest of Blackhawk Lake. After development, it is anticipated that the front yards of the proposed development will drain to a shallow ditch system along Blackhawk Road which will convey the water to Highway 13 to the west. This water will not reach any recreational class water body. The back yard area will drain in a southerly direction as it does now toward Pond AP-27, a pond classified for use as a wildlife habitat in the City water quality management plan. Since this area of the lots will neither contain impervious area nor discharge directly to the pond (the rear of the lots does not reach the pond), negligible impact is expected to AP-27 from this development. Because of the low density of the proposed development and the fact that runoff generated by the development will not discharge directly to a recreational class water body, a cash dedication to satisfy water quality requirements would be acceptable for this development. WETLANDS A review of the site by City staff showed no wetlands subject to Wetlands Conservation Act jurisdiction on-site. /5 s WATER QUALITY REQUIREMENTS July 20, 1992 Page Two STAFF RECOMMENDATIONS Staff recommends that the development be subject to a cash water quality dedication. The amount of the cash dedication is estimated at $1,036. Rich Brasch Water Resources Coordinator RB/sb 29wp.advis2.202 /G . AA Ab Ficrure C - - CP-9 . R.L. 4 C CL. V JO C-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 in its Water Quality Management Plan. WATER DUALITY ANALYSIS The proposed development is located in drainage basin G, northeast of Burr Oak-Park. All stormwater originating on the site drains to the north toward Highway 55. Run-off will be carried in a grassy ditch to Pond GP-2, identified as a nutrient trap in the City water quality plan. GP-2 in turn discharges to Bur Oak Pond (GP-1), a Class II recreational water body. Because of the small size and low density of the development proposed, impacts to the receiving water body as a result of this development are expected to be negligible. As a result, a cash dedication to meet water quality requirements for this development will be acceptable. WETLANDS Staff conducted a site reconnaissance on July 20, 1992. This survey indicated the presence of several small wetlands on the northern one-third of the site at the base of the slope on the property. However, all wetlands are located well outside proposed grading limits. No filling or draining of the wetlands is being proposed. WATER QUALITY REQUIREMENTS July 22, 1992 Page Two STAFF RECOMMENDATIONS Staff recommends that the development be subject to a cash dedication to meet water quality requirements. The amount of the cash dedication is estimated at $522. Rich Brasch Water Resources Coordinator RB/sb 29wp.advisl.204 %04. V 11 F-f Figure P-8 aJ do. T„ CL.

V o ,v ~ t _ MEMO TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: RICH BRASCH, WATER RESOURCES COORDINATOR DATE: JULY 31, 1992 SUBJECT: WATER QUALITY REQUIREMENTS AND WETLANDS ISSUES FOR ST. THOMAS BECKETT ADDITION PROPOSAL This preliminary plat application consists of approximately 33.1 acres for a church located along the west side of Highway 3 south of Diffley road in the southeast one quarter of section 25 (Figure 1). The land is currently zoned for agricultural uses so a change in zoning to public facility use has been requested as well. FOR COMMISSION REVIEW The Commission will need to review and make a recommendation regarding whether the development should be subject to a ponding requirement and/or a cash dedication requirement to meet water quality standards as set by the City in its Water Quality Management Plan. There are also wetlands impact issues associated with this plat. WATER DUALITY ANALYSIS, This 33.1 acre parcel is located in Drainage Basin L due west of Hay Lake on either side of State Highway 3. The area of the site that lies west of Highway 3 will be the location for a church and parking lot. This portion of the site is 23.1 acres in area of which approximately 6.8 acres will be covered by impervious surfaces, 4 acres will be covered by water, and the remainder will be covered by maintained turf or natural vegetation. No grading or construction is proposed for the remaining 10 acres of the site to the east of Highway 3. The site contains several water features. Hay Lake, a Class 11 lake designated to support indirect contact recreation, is located along the western edge of the development. In addition, the site also contains a small pond in the southeast comer (designated LP-47.1 on Figure 2) and another wetland designated LP-47 lies just off site to the south. LP-47 is designated as a nutrient trap in the City Water Management Plan. Run-off from this site will eventually reach Hay Lake. If not treated prior to discharge to Hay Lake, the City water quality model indicates a degradation of this Class II lake would result. Since this is not acceptable under current City policy, on-site is recommended to fully meet water quality treatment requirements for the development. c3 . WATER QUALITY REQUIREMENTS July 31, 1992 Page Two To treat run-off prior to discharge, the developer proposes to direct all run-off from impervious areas to LP-47.1 where it will be discharged to LP-47 before entering Hay Lake. Because the current water surface elevations of both LP-47.1 on the development property and LP-47 are below that of Hay Lake, the normal water level of these ponds will need to be raised. In doing so, the surface area and wet pond volume of the small pond will increase from .8 acres and 1.8 acre feet to about 1.4 acres and 9.8 acre-feet. This increase in volume will provide the treatment capacity needed to mitigate potential impacts to Hay Lake. WETLANDS Based on preliminary information from the developer, there appear to be two sets of wetlands comprising a total of 1.9 acres on that portion of the site proposed for grading and construction. One is associated with the small pond in the southeast corner of the site. The developer proposes to fill .17 acres of the wetland during grading of the site. The area proposed for filling lies almost entirely on the Minnesota Department of Transportation (MnDOT) right-of-way for Highway 3. The developer has indicated that MnDOT wants this area filled to improve safety characteristics for this stretch of highway. By increasing the normal water level of the pond from elevation 901.6 to elevation 908 to allow gravity discharge toward Hay Lake, the developer estimates that .85 additional acres of the pond and associated wetland fringe will be created. This will exceed the 1 to 1 replacement requirement under the Wetland Conservation Act. The second wetland complex is a wetland fringe along Hay Lake. Because of the importance of this fringe in providing a buffer to Hay Lake, draining or filling of this wetland should be avoided. The developer has not yet staked this fringe, but should be required to do so prior to issuance of a grading permit or approval of final plat. If these recommendations are followed, there will be a net increase of .68 surface acres and wetland area on the site. STAFF RECOMMENDATIONS Staff recommends the following: 1) The developer 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. WATER QUALITY REQUIREMENTS July 31, 1992 Page Three 2) The wetland fringe along Hay Lake must be delineated according to Wetlands Conservation Act criteria and avoided during construction and post-construction activities. 3) 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.

Staffs effort since January has been directed toward the first compliance requirement. '--By July 26, 1992 the City must provide a transition plan which: o Evaluates the accessibility of all City facilities o Identifies structural barriers to accessibility o Outlines what structural changes can reasonably be made By January 26, 1993 o All barriers to program accessibility must be identified o A plan to remove barriers to participation in City programs must be in place FOR COMMISSION'S INFORMATION The Department is fortunate that most of the park facilities have been constructed since 1984 and meet the accessibility standards that were required at that time. Staff and a volunteer who uses a wheelchair assessed Trapp Farm Park. Possible barriers to accessibility were noted. Examples are: The drinking fountain adjacent to the pavilion can not be routinely accessed by wheelchair. The concrete approach to the exterior door to the women's restroom is narrow, access by wheelchair is precarious. Access to the restrooms from inside the shelter is readily available. Two other minor notations were made. The faucets in the restrooms are somewhat difficult to operate from a wheelchair. And, the telephone is mounted higher than what can be readily reached from a wheelchair. ADA UPDATE PAGE TWO JULY 22, 1992 The minor barriers mentioned above serve as the check points for the City's other shelters. At Goat Hill, for instance, the concrete approach and wheelchair turn area are sufficiently wide for the exterior restroom access, however, the natural gas meter location, narrows the "path", forcing a wheelchair onto the grass. The Rahn building built in 1976, has significant barriers. The restrooms are not wheelchair accessible at all. The City's self assessment, conducted in 1984, rated the entrance 57% accessible and the interior 71% accessible. To ensure program accessibility, an acceptable immediate alternative to structural changes to facilities is to provide either auxiliary aids or the option of an alternate site. However, structural changes, identified in the transition plan are required to be completed by January of 1995. Phase two of the ADA study will assess accessibility program by program. Staff's understanding is that each recreation program will need to be assessed! 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. There is no Commission action necessary for this item. DP/bls . ADVISORY PARKS, RECREATION & NATURAL RESOURCE COMMISSION DEPARTMENT HAPPENINGS JULY 30, 1992 1.*<< Evening in the Park was rained out on July 22. In thirteen (13) years of conducting these events, this was the second rain out. Magician David Bradshaw will perform on August 19. The event will be at Cedar Pond Park and as originally planned, donations for the food shelf will be accepted. 2.*<< The Co-recreational tennis league has been plagued by rain. Play has had to be canceled due to drenched courts on three of the last six Wednesday evenings. Make- ups are difficult due to the participants busy schedules. 3.*<< Sixty-one (61) youth are playing in the South of the River tournament on July 30 & 31. Last year's tournament had 59 participants. The major difference this year is all participants are from local communities. Last year 19 Northfield youth took part. 4. NYSCA coaching clinics for soccer and football will be held during the first week in August. Benita Soller, former intern, has been certified as a clinician to assist Recreation staff in conducting clinics. 5.*<< Staff recently attended a problem oriented policing seminar sponsored by the Police Department. Parks and Recreation staff have been serving on a committee for the Police Department that is studying community oriented policing. Of interest to Parks and Recreation are youth at-risk. Knowledge staff gains through this committee will be helpful in sensitizing staff to the needs of this youth population. New aspects for staff training are expected to evolve also. 6.*0 Staff anticipates receiving field use requests from Dakota Hills Middle School within a week or two. In past years the City has provided football practice space and soccer facilities for the school. It is not yet known whether the Middle School soccer field facilities will be used this fall. The turf is improving very slowly! 7. * << Adult softball ends League play by August 5. Play-offs occur August 1 and 2, August 8 and 9, and we host region and state tournaments August 14-16 and August 28-30. 8. * << In-line skating lessons were introduced and a small number of beginners and intermediates took advantage. This is a good start for this fast-growing activity. 9.*« 3-on-3 Basketball goes well with six teams playing Mondays at Sky Hill and Bridle Ridge. 10..c< Work continued on construction of the playground at Trapp Farm Park. The Twin Cities Tree Trust Organization assisted City staff in the completion of the decking and boardwalk facilities, and distribution of playground surfacing material. In addition, several dozen trees and shrubs were planted around and within the play structure and more than 2,000 yards of sod was installed. A concrete walk-way was also poured between the bituminous trail and playground, providing handicap accessibility to the structure. Our thanks go to Steve Hadden and Paul Szurek for their excellent leadership in this project. .3/. 11.*« Construction was completed on a new playground at Wescott Station Park. Parks Maintenance workers Alex Lammers and Don Buecksler are credited with another excellent job with this project. The project was also assisted by the Twin Cities Tree Trust Organization, who distributed playground surfacing material and installed three benches and a small retaining wall at the park. 12. * « Spot sweeping was completed on more than 70 miles of boulevard trails during the month of July. Some of the heavier rainfalls in June resulted in siltation and erosion on a number of trails throughout the community. 13. * << The County's sentencing to service program was back in Eagan Parks during the period of July 26th through August 10th. During this two week period the work crew pruned trees and overgrowth along numerous miles of park and boulevard trails, completing re-mulched and de-weeded all of the City's parks and assisted with a sumac removal project in the Thomas Lake Native Prairie. 14. * << In early July, the Parks and Recreation Department assisted with the set-up for the 4th of July Celebration held at Rahn Park. This included the delivery of additional tables, waste containers, temporary fencing and assistance with ground preparation and clean-up. 15. * << Parks Maintenance employees Steve Taylor and Dan Curtin shaped and re-graded the infields at Rahn, Goat Hill and Northview Parks. This project also involved washing and aglime along the edges of the infields, which builds up as a result of our daily dragging operations. This work is normally scheduled three times per year for the programmed softball fields in order to keep them in good playing condition. The new tanker truck purchased in May has been found to be a very effective piece of equipment in speeding up this type of maintenance work. 16. << In mid-July all of the City's irrigated athletic sites received a dose of mid-summer fertilizer application and were also slicer aerified. The aerification process helps to increase the permeability of the soil for water penetration and for air exchange with the root zone. Not surprisingly, these mowing routes continued to operate at full capacity during the month of July. The unseasonably wet weather and cooler temperatures resulted in a faster than average growing conditions for this time of year. The city is currently mowing and trimming about 380 acres of turf per week. 17. * << Phase I of the Landscaping Plan for Downing Park was completed in early July. Several new trees and shrubs were installed along the eastern perimeter of the park adjoining the town home development on Clemson Drive. *City Council - August 4, 1992 *Commission meeting - August 6, 1992 3z.

The site is currently zoned R-1 (Single Family) and is located south and west of the Blackhawk Road and Blue Cross Road intersection. BACKGROUND: The existing home was built in 1947. On November 6, 1985, the City Council approved a Waiver of Plat splitting the property into two parcels. The Waiver was requested to allow the Wilsons to sell the house on the approximately two-acre Parcel A. A condition of the waiver required platting of the approximately 2.5 acre Parcel B before any further development could occur. To insure the platting of the property, a $10,000 deposit in favor of the City was required as a condition of the waiver approval. The applicant is drawing against this deposit for the current application and escrow expenses. EXISTING CONDITIONS: The site is relatively flat and treeless on. the northern one-third, however the southern two-thirds contains moderate to severe slopes and significant tree growth. COMMENTS: The City Code requires an 85' minimum lot width at the building setback line and a minimum lot size of 12,000 sq. ft. in R-1 districts. The four proposed lots are all larger than one-half acre. The lots range in size from 28,875 sq. ft. to 86,000 sq. ft. All lots exceed lot width and area requirements. Access to all lots will be from Blackhawk Road. Due to the existing vegetation and range in grades, the applicant is proposing no site grading at this time. Individual lot preparation will be done by custom builders. Tree preservation should be achieved with a physical barrier. Protection of trees to be saved during site preparation should be enclosed with snow fencing or other suitable materials. PARKS & RECREATION: Parks & Recreation staff will be recommending a cash parks and cash trails dedication for the three undeveloped lots to the Advisory Parks, Recreation, and Natural Resources Commission at its August 6, 1992 meeting. The lot with the existing structure will be exempt from both parks and trails dedication. road and present (1989 A.D.T = 4,742)/future (projected A.D.T. = 7,100) traffic volumes, there is limited visibility creating safety concerns for individual driveway access onto Blackhawk Road. Therefore, each newly created lot shall be required to construct its driveway with a turnaround to eliminate the need for backing out onto Blackhawk Road. EASEMENTS/RIGHTS-OF-WAY/PERMITS: A 40' half right-of-way shall be dedicated for Blackhawk Road. In addition, sufficient easements shall be dedicated along Blackhawk Road for the installation of the sanitary sewer line. If detailed construction plans indicate the need for permanent or temporary construction easements from the adjacent property to the east, it shall be this development's responsibility to acquire all permanent and temporary utility easements prior to final plat approval. Permits will have to be obtained from the City of Eagan for construction within the Blackhawk Road right-of-way required by the installation of the individual water services. Permits will have to also be obtained from the MPCA and MWCC for the proposed sanitary sewer lateral extension. Detailed plans and specifications prepared by a registered engineer shall be submitted for review and approval by staff prior to final plat approval. FINANCIAL OBLIGATION - Wilson 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.

Lot 1, Block 1, is located south of Autumn Ridge 2nd Addition and is bounded on the east side of Highway 3. Lot 1, Block 2, is bounded on the west by Highway 3 and the Inver Grove Heights border to the east. BACKGROUND: In October 1989, the Archdiocese of St. Paul and Minneapolis announced the formation of the new church of St. Thomas Becket parish. Farmland on Highway 3, roughly halfway between Diffley and Cliff Roads was purchased as a permanent site. The parish community celebrated the first mass in February 1990 at a rented temporary worship site at Lone Oak Road and Lexington Avenue. Over the past two and one-half years, the parish has grown to almost 400 families. EXISTING CONDITIONS: The site is bisected by State Highway 3 and the Soo Line Railroad and contains areas of severe slopes, cultivated fields, wooded areas, and wetlands. Northern States Power Company has an easement over the northern 200' of the property. COMMENTS: The site plan proposes a 23.14 acre Lot 1, Block 1, and a 9.97 acre Lot 1, Block 2. The church has no current development plans for Lot 1, Block 2. The applicant is proposing a two-phase total building area of 58,384 square feet, with a total building footprint of approximately 44,000 sq., ft. and 348 parking spaces based on a 1,200 seat sanctuary when fully-developed. The first phase is scheduled for a Fall 1992 construction start. The applicant anticipates a 14-month construction period with occupancy by Christmas 1993. Phase I of the proposal includes an 800 seat sanctuary, a 2,200 sq. ft. sacristy, 4,400 sq. ft. administration area, a 7,000 sq. ft. gathering area, and a 2,700 sq. ft. mechanical area, SS• GRADING DRAINAGE/EROSION CONTROL: The proposed development consists of rolling topography, with dense grass cover and scattered wooded areas. There is a one-acre wetland (Pond LP-47) in the southeast corner of Lot 1, Block 1, and Hay Lake (Pond LP- 31) along the west edge of the site. The area of Hay Lake on this site is about four acres. Lot 1 of Block 2 contains a two-acre wetland (Pond LP-30) along its southerly edge. The preliminary grading plan proposes a substantial amount of grading on Lot 1, Block 1, and no grading on Lot 1, Block 2. The maximum cut is 16' and the maximum fill is 10'. Retaining walls are shown in four locations on the site. Detailed plans and specifications shall be submitted with the final grading plans for the proposed retaining wall construction. The drainage from the new parking lot and roof leaders from the new building shall be directed to an internal storm sewer system that discharges into Pond LP-47, which is a designated pond on the City's Stormwater Management Plan. Pond LP-47 currently receives runoff from adjacent undeveloped areas and Highway 3, and the pond does not have an outlet. The developer shall petition the City to construct the trunk storm sewer outlet for Pond LP-47 to Pond LP-31 before the final plat is approved by the City. The final grading plan shall provide a 30' buffer along Hay Lake to protect the edge of the lake's vegetation. The buffer should help to limit erosion of sediments into Hay Lake. Pond LP-47 shall also be protected from erosion of sediments from the site. The development will be responsible for installing and maintaining erosion control measures in accordance with the City's Erosion/Sediment Control Manual Standards. WATER QUALITY: This proposed development is located in drainage basin L. Discharge from the site will eventually reach Hay Lake, a Class II lake designated to support indirect contact recreation in the City's Water Quality Management Plan. Because runoff from this site would degrade water quality in Hay Lake if not treated, on-site ponding will be recommended to meet all water quality treatment obligations for the proposed development. This recommendation is subject to approval by the Parks, Recreation, and Natural Resources Commission. UTILITIES: Sanitary sewer service is available to serve the church from an 8" line in Atlantic Hills Drive. However, this line is not deep enough to serve the church's lower level. Therefore, the church is pursuing an alternative sanitary sewer layout that would drain to the south through the undeveloped property south of the church site. The sanitary sewer stub that is available to the south is approximately 1000 feet away at East Greenleaf Drive. The sanitary sewer stub to the south is deep enough to serve the basement level of the church. Water main of sufficient size, pressure and capacity is readily available to serve this development from the existing 8" water main in Atlantic Hills Drive and from the existing 8" water main in Tofte Lane in the Autumn Ridge 2nd Addition. The water main layout for the church shall include a connection to both of the 8" stubs and looping the water main to the south property line for future extension to Cliff Road. FINANCIAL OBLIGATION - Saint Thomas Becket 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. Improvement Use Rate Quantity Amount Sanitary Sewer P.F. $1495/Ac 33.11 Ac $ 49,499 Trunk Water Trunk P.F. $1565/Ac 33.11 Ac 51,817 Storm Sewer P.F. .104/Ac 1,441,364 S.F. 149,902 Trunk Water Availability P.F. $2470/Ac 33.11 Ac 81.782 Charge Total 333 The areas used include ponding areas. If ponding easements are dedicated to the City, the area used to compute financial obligations will be reduced, causing a corresponding reduction in the financial obligation.
