Staff looks forward to a productive year working with the Commission in meeting the needs of our community. As a reminder, we are meeting at 6:30 p.m. in the second floor conference room to introduce our three new Commission Members and spend a bit of time on procedural matters of the Commission. If we can get through this in a timely manner, the Commission may wish to begin discussion on the goals/work program for the coming year. After the Call to Order, Pledge of Allegiance and Approval of Agenda, appreciation plaques will be presented to Michael Vincent and Jerry Farlee for the time they spent on the Commission. Our thanks to both of these members who donated so much of their time to the betterment of the community. Commission organization is the first action item. Typically, staff serves as temporary chair to facilitate the election of the Chair, Vice-Chair and Secretary. Following this process the meeting is then turned back to the Chair, at which time the Commission can then determine the make up of the various sub- committees. The Commission may also choose to do this at the end of the meeting. The first item of business is the Consent Agenda. A single motion to approve is in order unless there is a motion to separate one of the items for discussion and action. Under Old Business, you will find a memo regarding the sub-committee's recommendations pertaining to "open space". Also under Old Business is a verbal report on the status of Skyline Display's "Discovery Park". Under New Business is the field maintenance agreement with Dakota Hills Middle School. Two years ago the City received a request to assist Dakota Hills Middle School with field maintenance to bring their facilities to the same level of quality as the City maintained playing fields. The school reimburses the City for expenses incurred. At that time the Commission recommended a two-year agreement which would be reviewed upon completion to determine if the agreement should be extended. Superintendent Olson and Maintenance Supervisor Taylor have met with the school's principal and assistant principal to discuss this program. This item has been placed on the agenda for review and recommendation to the City Council. Faithful Shepherd has also asked the City to consider a similar agreement for their new school as part of the agreement that is now under consideration. Staff is reviewing this issue at this time. 1 The second item under New Business is the appointment of two Commission Members to serve on the Cedarvale Area Redevelopment Task Force. This group is expected to meet monthly over the next 5-6 months to hear and advise the consultant on the preliminary design of the study area. This is the area on both sides of Highway 13 from Cedar Avenue to Silver Bell Road. SRF, the consultant hired to begin the process, has been ,working on some plans for the area and is expected to have them available to present to the Economic Development Committee on February 22. The balance of the meeting will be the standard updates for Parks Development, Water Resources, Subcommittees and Cascade Bay. The Commission should also set a date for a planning session workshop. We look forward to seeing everyone on the 11th. Should you not be able to attend the meeting, please call the Parks and Recreation office at 681-4661. Respectfully submitted, Ken Vraa Director of Parks and Recreation DEPARTMENT HAPPENINGS FOR FEBRUARY 1999 1. Merger of the Eagan Arts and Humanities Council and the Dakota Center for the Arts is near completion. The opportunity for offering adult classes in painting, ceramics and pottery is enhanced by the merger. 2. Donna Tilsner has officially assumed the responsibility of conducting programs for Senior Citizens. Look for some renewed outreach to younger retired persons this spring. 3. The Eagan Athletic Association has made National Youth Sports Coaches Certification Training mandatory for all coaches of children in grades K-2 and for coaches whose certification has lapsed. The program has been changed to one level of certification compared to the previous plan requiring attendance at 3 levels of clinics. It is unknown how the mandatory status will affect participation, the number of "make up" sessions staff will have to offer will be carefully monitored to prevent this one service to the community from getting out of hand. 4. Recreation staff have finished the planning and writing stage for the Spring/Summer issue of the Discover Us! Brochure. Postal delivery in the City will occur between February 22 and March 3. It was an enormous task for Recreation as well as clerical staff. 5. For the first time in several years, Parks and Recreation information will have a page in the School District 196 Spring/Summer Brochure. In addition to marketing Cascade Bay, the Department will provide general information on other spring and summer activities. 6. Friends of the Farm will host a clean up day at Holz Farm on Saturday, May 1, 1999. Beginning at 9:00 AM the Friends would look for volunteers willing to help rake the yard, perform some light carpentry and painting, fill in ruts in the driveway and clear some brush. Since the Garden Club's plant sale occurs the following Saturday, the 8`h, a spruce up of winter residue is needed. 7. The Department hosted a meeting of community programming staff on January 29, 1999. Representatives from other cities, Community Education, the Y, the Arts and Humanities Council, Caponi Art Park, the Library (to name a few) attended. The initial meeting was to gather information concerning programs offered in the community. Future meetings will hopefully lend themselves to co-operative programming and finally collaboration. All who attended found the meeting worthwhile. 8. During the latter part of February, Paula Nowariak will attend the second year of her Professional Development School at the University of Georgia. The slate of professors is again impressive. Contacts Paula made a year ago have been excellent sources of information for the department this year. 9. The bicycle trail kiosk signs are in, we only await spring to begin installation. Staff will keep an eye on the Highway 13 project for potential impact on the Silver Bell location. 10. Saturday, January 30 was a beautiful day weather wise, drawing hundreds of people to Trapp Farm Park. In addition to attracting tubing hill participants, approximately 150 people were fishing on Schwartz Lake with the assistance of Water Quality staff and In-Fishermen and nearly 200 dog sled rides were provided by Silver Creek Dog Sleds. As one might surmise, parking was difficult. Separation, time wise, of the fishing and dog sleds should again be addressed in the future. 11. Weather permitting, the warminghouse/ice skating program will come to an end on Monday February 15. The warm weather has already begun to show its signs or wear and tear on the ice. 12. Summer softball information has been mailed to all returning teams for the 1999 season. New teams have also been calling requesting information about the program. Registration begins March I". 13. State tournaments for the winter adult leagues are coming up in March. Eagan will be sending a number of teams to the various tournaments. • Basketball - I team • Broomball - 3 teams • Co-rec Broomball - 1 team • Women's Volleyball - 5 teams • Men's Volleyball - 2 teams • Co-rec Volleyball - 2 teams 14. Approximately 100 people enjoyed the Family Fun Night at Blackhawk Middle School on Friday January 29, 1999. Swimming, playing and refreshments were enjoyed by all. The next Family Fun Night is on Friday, February 26 from 6:00-8:00 p.m. at Blackhawk Middle School. 15. There are close to 200 preschoolers involved in the Parks & Recreation winter Preschool. Programs. Goat Hill, Bridle Ridge and Rahn Park Shelter Buildings serve as the location for the program. The participants are getting excited for their Valentine Parties this week and an upcoming field trip to the Children's Museum. 16. Sesame Street Live at Target Center was the destination for 60 participants on January 22. Participants saw Elmo, Big Bird and the rest of the Sesame Street friends in an entertaining musical performance about "When I Grow Up" 17. In the Quarry Park Neighborhood, plans for a "Spring Hoopla" are in the works for March 9t'. This is an event in collaboration with District 197. Its focus will be on building a strong community. 18. The recent warm weather has taken a toll on the outdoor ice rinks. The maintenance staff is making every effort to keep them useable through the scheduled closing date of February 15. Priority will be given to the "A" sites. 19. Due to low oxygen levels, aerators have been installed on Thomas Lake, Blackhawk Lake and Burr Oaks Lake. Holz Lake is the next likely site. Staff will continue to monitor the other priority lakes. 20. Thanks to the thick lake ice, staff has been able to access trees located along remote or inaccessible shorelines that were damaged during the May storm. 21. The Department of Natural Resources recently notified the City that the application for a fishing pier at Schwartz Lake (Trapp Farm Park) had been approved. The DNR will provide the pier to the City for 20 years. The City is required to install a concrete pad to serve as a base for the ramps. 22. There are a variety of seasonal park maintenance positions available this year. Starting dates range from April through June. Interested persons 18 years and older are encouraged to apply at the Municipal Center or Maintenance Facility. Retirees are encouraged to apply. 23. Orders have been placed for several pieces of large maintenance equipment. Both large rotary mowers (580D) and a one ton dump truck will be replaced. An additional one for dump truck will also be added to the fleet. Though both mowers were very high in use hours, the Department received trade value well in excess of the average value thanks to its well refined preventative maintenance program. 24. A community "open house" is scheduled for the Civic Arena the evening of June 3`d. City departments will have displays and equipment available for viewing. 25. The Friends of the Farm are in the process of developing a project list for 1999. Projects being considered include re-roofing the barn and several sheds, painting the exterior of the house, building a silo and a variety site enhancements. A membership mailing recently went out to nearly 275 persons who had registered for the Lone Oak Days raffle. 26. The 1999 contract with Dakota County for the provision of Sentence to Serve work crews has been approved. Staff has begun compiling a list of potential projects.

MEMO J city of eagan TO: ADVISORY PARKS COMMISSION FROM: PAMELA DUDZIAK, ASSOCIATE PLANNER DATE: FEBRUARY 5, 1999 SUBJECT: NADER ADDITION - NADER NOORYSHOKRY BACKGROUND Nader Nooryshokry is requesting approval of a Preliminary Subdivision (Nader Addition) to create 3 lots on 1.56 acres on property located at the corner of Highview Avenue and Bridgeview Terrace in the southwest'/4 of Section 4, legally described as Lot 1, Block 1, Joseph A Spande Addition except the east 90 feet thereof. In June 1995, a preliminary subdivision (Hayes Addition) consisting of four lots was approved for Lot 1, block 1, Joseph A Spande Addition, but the applicant did not follow through with the final subdivision and the preliminary approval expired. Subsequently, a single-family home was constructed on the "exception" parcel. Mr. Nooryshokry has since purchased the balance of the site and is proposing to complete the subdivision that was started in 1995. The proposed subdivision is essentially the same as it was in 1995. The site is wooded and has a ravine, wetland and spring in the southern portion of the site. There is an existing single-family home located on what will become Lot 2. The other two lots are proposed to be custom-graded. Retaining walls are proposed between the lots to accommodate the necessary grade changes. In 1998, the City completed a public improvement project for this neighborhood, which included street reconstruction and the extension of water main and sanitary sewer services. PARKS/TRAILS DEDICATION This development would be subject to a cash parks dedication and a cash trails dedication. TREE PRESERVATION This proposed four-lot development, which currently has two residences on it, is located on the corner of Highview Avenue and Bridgeview Terrace in the SE'/4 of Section 4. This property was platted as the Hayes Addition on June 6, 1995. The original house is located on what will become lot 2. The "exception" lot has a recently constructed house on it. Lots 1, 2, and 3 have either landscape trees or woodlands on them. A linear wetland with springs is located behind lots 1, 2, and 3. J Significant Vegetation A tree inventory was prepared for this site in 1995 (Vernix Forestry Consultants) and has been submitted with this application. It indicates that there are 9,800 sq. ft. of significant woodlands and 45 significant individual trees within this site. The woodlands lay along the south edge of the property and are comprised of cottonwood, elm, boxelder, willow, and ash trees. The 45 individual trees are located in the north half of the site and are comprised of spruce, pine, and cedar trees (17 to 34 feet in height), and maple, elm, oak, and cottonwood trees (9 to 27 inch diameter). A bur oak tree measures 27 inches in diameter. The applicant is proposing to sell lots 1, 2, and 3 and have each lot custom graded. Recommendation To acknowledge that Individual Lot Tree Preservation Plans will be required at the time of building permit application for lots 1, 2, and 3. WATER QUALITY/WETLANDS This development is located in Drainage Basin H in northwest Eagan. This 1.6 acre development will generate runoff that will be discharged to a large culvert under Highway 13 and into the wetland complex along the Minnesota River. There are no recreational classified water bodies downstream of the proposed development. Because this is a small development, and there is already one natural wetland located on the site, staff recommends that no on-site ponds be constructed to treat runoff from the impervious areas of the development parcel. However, a cash dedication in lieu of on-site ponding is recommended. There is one jurisdictional wetland within the development parcel. Staff recommends that: • A cash dedication in lieu of on-site ponding be required for the development. The cash dedication required based on the area and impervious characteristics of developed lots will be from $650 to $700. • An undisturbed and unmaintained buffer extending at least 30 feet back from the delineated boundary of wetlands will not be required since this is a continuation of a proposal submitted before the City Ordinance was in place. FOR COMMISSION CONSIDERATION 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication. 3. Individual Lot Tree Preservation Plans will be required at the time of building permit application for lots 1, 2, and 3. 4. This development shall be responsible for a cash dedication of approximately $650-$700 based on the area and impervious characteristics of developed lots in lieu of on-site ponding. 5. An undisturbed and unmaintained buffer extending at least 30 feet back from the delineated boundary of wetlands shall be preserved.

The proposed subdivision overlays 9.8 acres of land located north of Crestridge Lane between I-35-E and Pilot Knob Road upon property currently platted as Lot 1, Block 1, Duckwood Bluff. In October of last year, the City Council approved a Planned Development for a 95 room, "extended stay" hotel (TownPlace Suites) upon the northern one half of the subject 9.8 acre property. Because the existing "Fairfield Suites" and "TownPlace Suites" are to be under common ownership, the applicant initially desired to locate both facilities upon a single lot of record. For various reasons, the applicant has now decided to pursue the subdivision of the property. The southern portion of the subject site is presently occupied by the Fairfield Suites hotel. The northern portion of the site is vacant but was rough graded as part of previous development. A portion of the subject site lies within the shoreland overlay district of Fish Lake that establishes a maximum impervious surface coverage requirement of 25 percent. This item is scheduled for consideration at the forthcoming February 23 APC Meeting. PARKS/TRAILS DEDICATION This development would be subject to a cash parks dedication and a cash trails dedication. TREE PRESERVATION This 10-acre site is located just north of Fairfield Suites Hotel on Duckwood Drive and Crestridge Drive in the SE '/4 of Section 16. There is no significant vegetation on this site. ',1 WATER QUALITY/WETLANDS This development is located within the watershed of Pond JP-3, a sediment basin which discharges to Fish Lake, a Class I direct contact recreation water body. Staff recommends on- site ponding to treat this runoff prior to discharge to Pond JP-3. The development parcel is mostly open grassland and gently rolling, with a topographic difference of only 10 feet from the northeast corner to the south side of the property. Staff recommends that the existing storm water pond is adequate to treat the runoff from this development. There are no jurisdictional wetlands within the development parcel. Staff recommends that: • The existing on-site pond located in the southwest corner of the site is adequate in size and volume to provide on-site treatment for storm water runoff from this parcel.

In conjunction with the requested preliminary subdivision, the applicant has also requested a Comprehensive Guide Plan Amendment to change the guided land use of the subject property from PF, Public Facilities to D-I, Single Family Residential and a rezoning from a PF, Public Facilities to an R-1, Residential Single Family zoning designation. The subject 10 acre property slopes gently to the south. Approximately 2.5 acres of the property is comprised of a wetland (Pond LP-30). Some significant trees exist in the southern portion of the site (along the referenced pond). The site also lies within the shoreland overlay district of Hay Lake (a general development lake). All lots within the subdivision are proposed to served by water and sanitary sewer that was extended by Inver Grove Heights under a joint powers agreement to serve the adjacent Southern Lakes subdivision. This item is scheduled for consideration at the forthcoming February 23 APC Meeting. PARKS/TRAILS DEDICATION This development would be subject to a cash parks dedication and a cash trails dedication TREE PRESERVATION Site History This 10-acre site is located east of Highway 3, west of Inver Grove Heights, and north of Pond LP 30 in the SE'/4 of Section 25. The site is bound on the east by the Southern Lakes development and on the west by railroad tracks. The site actually appears as an extension of the Southern Lakes development, as the entrance road extends from this Inver Grove Heights development. Significant Vegetation A tree inventory has been submitted for this site. It indicates that there are 48 significant trees existing on site. All of these trees are located on the extreme west and south (which is the north shoreline of Pond LP 30) boundaries of the site. The development of this site will not disturb any of these trees. The developer, Springbrook Corporation, has indicated that the preservation of the existing trees is a "high priority as the site is impacted by South Robert Trail and the Soo Line Railroad". He also states that "the trees along the pond add value to the pond lots and a visual buffer to the future church site and highway activity across the pond". Staff is recommending approval of the Tree Preservation Plan as proposed with the following conditions: To require that Tree Protective measures (i.e. orange colored silt fence or 4 foot polyethylene laminate safety netting) be installed at the Drip Line or at the perimeter of the Critical Root Zone, whichever is greater, of significant trees/woodlands to be preserved. To require that the applicant contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. WATER QUALITY/WETLANDS This development is located within the watershed of Pond LP-30, a Class II indirect contact recreation water body. Staff recommends on-site ponding to treat this runoff prior to discharge to Pond LP-30. The development parcel is mostly open grassland and gently rolling, with a topographic difference of only 20 feet from the northeast corner to the south side of the property before it drops down a wooded hillside to LP-30. Staff recommends that the low area in the southeast corner of the site be used to construct a stormwater pond to treat runoff from this development. The excavation should be conducted to include a 10 foot wide safety bench just below the normal water elevation and that the side slope below the bench not exceed 3:1. The pond should have a minimum wet volume of .3 acre-feet. There is one jurisdictional wetland within the development parcel located along the shoreline of LP-30, which will be protected by a 50 foot unmaintained buffer strip. Staff recommends that: • An on-site pond be constructed in the southeast corner of the site to provide on-site treatment for runoff from this parcel. The pond excavation should incorporate a 10-foot wide aquatic bench extending from NWL to 1 foot below NWL and side slopes below the aquatic bench should be 3:1 to a maximum depth of 4 feet. The pond should have a minimum wet volume of 0.3 acre-feet. • An undisturbed and unmaintained buffer extending at least 50 feet back from the delineated boundary of LP-30 be preserved. FOR COMMISSION CONSIDERATION 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication. 3. Recommending approval of the Tree Preservation Plan as proposed with the following conditions: • To require that Tree Protective measures (i.e. orange colored silt fence or 4 foot polyethylene laminate safety netting) be installed at the Drip Line or at the perimeter of the Critical Root Zone, whichever is greater, of significant trees/woodlands to be preserved. • To require that the applicant contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. 1~L 4.

The eastern portion of the site received a preliminary subdivision approval for five lots in July 1997. The developer has since acquired the adjacent parcel to the west and has revised the development plans to include this additional land. The property is unplatted and contains a single-family residence in the southwest corner of the site. There are pockets of wooded areas in the south and southeast portions of the site. A portion of the eastern portion of the site has been cleared in accordance with the preliminary subdivision plans previously approved. Access to the site will be provided from Blackhawk Road. The proposed development has a density of 2.2 units per acre. PARKS/TRAILS DEDICATION This development would be subject to a cash parks dedication and a cash trails dedication TREE PRESERVATION This 4.6-acre site is located on the west side of Blackhawk Road at the intersection of Blue Cross Road in the NE 1/4 of Section 17. This application is a replat of a July 7, 1997 approval that will now create nine single-family lots. Significant Vegetation A tree inventory has been submitted for this site (it does not include a tabular list of significant trees). The inventory indicates that the significant trees are generally located in the south half of this site. Tree species include oak trees (6" to 22" diameter), elm trees (12" to 22" diameter), ash trees (6" to 22" diameter), and several conifers (approximately 30 feet in height). The applicant is proposing to custom grade the lots within this development. Recommendation To acknowledge that Individual Lot Tree Preservation Plans will be required at the time of building permit application for lots 4, 6, 7, 8, and 9. WATER QUALITY/WETLANDS This development is located in Drainage Basin A in northwest Eagan. This 4.5 acre development will generate runoff that will be discharged to a stormwater pond near Robin Lane, which then discharges to a stormwater pond near Highway 13, which then discharges to a culvert under Highway 13 and into the wetland complex along the Minnesota River. There are no recreational classified water bodies downstream of the proposed development. Because this is a small development, staff recommends that no on-site ponds be constructed to treat runoff from the impervious areas of the development parcel. However, a cash dedication in lieu of on-site ponding is recommended. There are no jurisdictional wetlands within the development parcel. Staff recommends that: • A cash dedication in lieu of on-site ponding be required for the development. The cash dedication required based on the area and impervious characteristics of developed lots will be from $2,625 to $2,885. FOR COMMISSION CONSIDERATION 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication. 3. Individual Lot Tree Preservation Plans will be required at the time of building permit application for lots 4, 6, 7, 8, and 9. 4. This development shall be responsible for a cash dedication of approximately $2,625 to $2,885 based on the area and impervious characteristics of developed lots in lieu of on-site ponding.

MEMO city of eagan TO: ADVISORY PARKS COMMISSION FROM: PAMELA DUDZIAK, ASSOCIATE PLANNER DATE: FEBRUARY 5, 1999 SUBJECT: PRELIMINARY SUBDIVISION (CHERRYWOOD KNOLL) BACKGROUND Heritage Development is requesting approval of a Preliminary Subdivision (Cherrywood Knoll) and a Preliminary Planned Development to create 36 lots and two outlots on 12.1 acres at 502 Chapel Lane located at the east end of Chapel Lane, south of Hwy. 55 and northeast of Bur Oaks Park in the northeast 1/4 of Section 12. The property is unplatted and contains a single-family residence in the central part of the site, which was constructed in 1966. The site is largely wooded. On the southern portion of the site the highest elevation is 902 and drops to 822 at the west boundary. The northern portion of the site has elevation changes from 864 sloping down to 822 at the northern boundary along Hwy. 55. An easterly extension of Chapel Lane is proposed to provide access to this development. The proposed development has a gross density of about 2.9 units per acre, which is within the allowable density of 3 units per acre. The Planned Development is proposed to allow for greater flexibility in site design and preservation of natural areas. The lots are clustered in the center with the north and western portions of the site designated as outlots. Outlot B (1.2 acres) is proposed as park land dedication to the city; Outlot A (2.9 acres) will be left as open space. Both outlots will be left largely undisturbed except for the grading necessary for stormwater ponding. This Planned Development includes deviations from several Code requirements typical for single-family homes. These are minimum lot size, minimum lot width and street frontage, and side and front yard setbacks. This development is designed with small lots (averaging 7,400 sq. ft.) containing single-family detached homes constructed with a zero setback on one side. Front yard setbacks are proposed to be 20 feet. PARKS/TRAILS DEDICATION The 12.1 acre development would be responsible for land dedication of 1.2 acres (10%) or a per unit cash dedication. The developer has proposed to dedicate Outlot B consisting of 1.23 acres to the City to fulfill the dedication requirement. Outlot A consisting of 2.9 acres, including the required requested ponding, would be dedicated to the homeowners association as an undeveloped open space. 9 Discussion Outlot B borders the northeast corner of Bur Oaks Park and the corridor that provides access to the park from the north. Outlot B has nearly 100% tree cover that includes a large number of significant trees. The outlot slopes steeply to the west with grades in many areas at or near one to one (100%/45 Because of the steep slopes the potential to use the outlot as an active park space is very limited. Any gading activity would require the removal of trees and create the potential for significant erosion. The value to the park may be as a visual amenity that provides screening from the development while also preserving a portion of the existing woodland resource. When evaluating potential land dedication, full credit has typically not been given to those areas having slopes exceeding approximately one to seven (15%). Steep slopes can make development costly and very prohibitive. In keeping with this policy, granting full credit towards the land dedication requirement through the dedication to the City of Outlot B may not be appropriate. As an alternative, requesting that a conservation easement or other non-development clause be placed upon Outlot A may be a means of compensating for the steep slopes of Outlot B. Because of the adjoining highway 494 corridor, limited access and the proximity of an existing park the need for Outlot A to be a dedicated park space is negligible. Staff is recommending that the Advisory Commission give consideration to the following: • The Trails Dedication be in the form of a cash payment at the rate specified in the 1999 City Fee Schedule. • The Park Dedication be met through the acceptance of Outlot B totaling 1.23 acres and the creation of a conservation easement or other non-development clause covering Outlot A. • Any encroachment onto Outlot B as part of construction or grading of the development site would require prior approval by the City. Those portions of Outlot B disturbed by construction or grading of the development site be restored by the developer in a manner deemed appropriate by the City. • Every effort be made to control erosion onto adjoining properties during development. The specific requirements of the City are to be considered as the minimum standard. TREE PRESERVATION This 12 acre site is located on the south side of Hwy 55 at the east end of Chapel Lane in the north half of Section 12. The site currently has one single-family residence on it located in the middle of the site. Approximately 75% of this site is covered with some type of significant vegetation. The north 1/3 and southwest'/2 of the site has steep terrain with existing elevation changes from 814 feet to 902 feet. Significant Vegetation A tree inventory has been submitted for this site. It indicates that there are 374 individual significant trees on site. Individual tree species include oak, birch, ash, hackberry, cottonwood, aspen, black cherry, boxelder, basswood, apple, and spruce. Diameters range from 6 inches to over 30 inches. There are also areas of this site that contain smaller diameter hardwood deciduous trees (less than 6 inches) and smaller diameter softwood deciduous trees (less than 12 inches) growing between the individual 374 identified significant trees. Areas of this type of vegetation are located in the north party of Outlot B, southwest of Outlot A, and southwest of the existing residence. These areas are smaller in size than what would comprise a significant woodland, but they are an integral part of the vegetation of the entire site. Basically, the trees and woodlands of this development site make up what can be described as a typical mixed northern hardwoods stand. There is almost complete crown cover of the wooded area, with an ideal understory of mixed small trees, shrubs and forest groundcover. The development as proposed will result in the removal of 188 significant trees (50.3% of the total). According to the City of Eagan Tree Preservation ordinance allowable removal for this type of development (multiple-lot single-phase single-unit residential) is set at 40% (150 trees). With a significant tree removal in excess of allowable limits there will be tree mitigation applied to this application. As the development is currently proposed, tree mitigation calculates to one hundred (100) Category B trees (or an equivalent number of Category A or Category C trees) or a cash mitigation of $30,000.00. Staff feels there is still an opportunity to reduce tree removal on this site. Recommendations are provided below. Recommendations are also provided that are standard procedure for compliance with the Tree Preservation Ordinance. Tree Loss in Pond Area Staff (Forestry and Water Resources) is recommending that the applicant redesign the proposed storm water pond located in Outlot A to reduce tree removal in this area. The applicant shall submit a revised Tree Preservation Plan following this requested re-design. Preliminary tree counts by staff indicate that at a minimum an additional seven significant trees will be preserved by implementing a redesigned pond. In addition about approximately 12,000 square feet of woodlands within this outlot will be left in an undisturbed state. Utility Installation Through Outlot B The applicant is currently prosing to install a water main pipeline through the northern section of Outlot B. The associated construction activity with this water line would require that a thirty to forty foot wide area, down the entire hillside of this outlot be cleared of vegetation. This operation would result in the removal of atleast five significant trees (oaks, ash, and elm 9" to 18" diameter) and in the removal of about 3,000 square feet of woodlands. With this type of hillside clearing there would be the potential of soil erosion and the visual unsightliness of a maintained easement down this hillside. Staff is suggesting re-routing this water main installation to an area avoiding Outlot B. A possible re-location would be to either side of Lot 12, then west along the south lot lines of Lots 1, 2, and 3. Correctly Place Tree Protection Fence According to the City of Eagan Tree Preservation Ordinance tree protection fencing shall be install either at the drip line or at the perimeter of the Critical Root Zone (CRZ), whichever is greater, of significant trees or woodlands to be preserved. The outer edge of the CRZ is defined as being a distance of one foot per one inch of tree diameter. The submitted Tree Inventory/Tree Preservation Plan needs to be revised to show the correct placement of this required tree protection fencing. Proposed Retaining Wall Near Outlot B To reduce construction impacts into Outlot B, the applicant is proposing to construct a retaining wall behind Lots 13 and 14. Staff is recommending that a field review of the placement of this wall and associated construction impact area take place involving city forestry staff and representatives of the applicant. It is desirable to not have this wall or the associated tree impact extend into Outlot B. Tree Mitigation/Landscape Plan According to the City of Eagan Tree Preservation Ordinance, when 10 or more replacement trees are required, not more than fifty (50) percent of the replacement trees shall be of the same species. Currently the applicant is prosing to fulfill tree mitigation with the installation of 100% Marshall seedless ash trees. Staff is recommending that a revised Tree Mitigation/Landscape Plan be submitted that includes a variety of tree species. The required number of mitigation trees shall also be revised pending the final significant tree removal resulting from above mentioned revisions. Additional Concerns The southwest portion of this development is directly adjacent to the northeast portion of Bur Oaks Park. This is of particular concern as the southeast wooded hillside of the development site is an important viewshed from most of the park. This heavily wooded hillside is visible from both the south part of Bur Oaks Park (a critical view across the lake) and from the north part of Bur Oaks Park (from the playground and picnic area). Staff feels that it is critical to preserve this view shed. Recommendation Staff is recommending denial of the Tree Preservation Plan until the following conditions are met. Recommendations to reduce tree removal To require that the applicant redesign the storm water pond located in Outlot A as proposed by City Water Resource staff. To recommend that the applicant reroute the proposed water main installation to avoid impact to Outlot B. Standard Conditions To require that the applicant submit a revised Tree Preservation Plan and revised Tree Mitigation Plan following adoption of staffs' recommendations. To require that Tree Protective measures (i.e. orange colored silt fence or 4 foot polyethylene laminate safety netting) be installed at the Drip Line or at the perimeter of the Critical Root Zone, whichever is greater, of significant trees/woodlands to be preserved. To require that the applicant contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. WATER QUALITY/WETLANDS This development is located within the watershed of Burr Oak Lake, a Class II indirect contact recreation water body. Runoff from the site will be discharged first to Pond GP-2, a 2-acre pond designated as a nutrient trap in the City's water quality management plan. Pond GP-2 in turn discharges via a lift station to Burr Oak Lake. Staff recommends on-site ponding to treat this runoff prior to discharge to Pond GP-2 and then to Burr Oak Lake. The development parcel is very hilly, with a topographic difference of almost 100 feet from the south-central to the northwest corner of the property. In addition, the majority of the parcel is heavily forested. Staff recommends that the low area in the northwest corner of the site be used to construct a stormwater pond to treat runoff from this development. The excavation should be conducted to include a 10 foot wide safety bench just below the normal water elevation and that the side slope below the bench not exceed 3:1. The pond should have a minimum wet volume of .22 acre-feet. A cash dedication in lieu of onsite ponding for graded areas not treated by proposed pond is recommended. There are no jurisdictional wetlands within the development parcel. Staff recommends that: • An on-site pond be constructed in the northwest corner of the site to provide on-site treatment for runoff from this parcel. The pond excavation should incorporate a 10-foot wide aquatic bench extending from NWL to 1 foot below NWL and side slopes below the aquatic bench should be 3:1 to a maximum depth of 4 feet. The pond should have a minimum wet volume of 0.22 acre-feet. • A cash dedication in lieu of on-site ponding be required for the graded areas in the development not treated by the proposed pond. 3 FOR COMMISSION CONSIDERATION 1. This development shall be responsible for a cash trails dedication. 2. The park dedication be met through the acceptance of Outlot B totaling 1.23 acres and the creation of a conservation easement or other non-development clause covering Outlot A. 3. Any encroachment onto Outlot B as part of construction or grading of the development site would require prior approval by the City. Those portions of Outlot B disturbed by construction or grading of the development site be restored by the developer in a manner deemed appropriate by the City. 4. Every effort be made to control erosion onto adjoining properties during development. The specific requirements of the City are to be considered as the minimum standard. 5. Denial of the Tree Preservation Plan until the following conditions are met: • To require that the applicant redesign the storm water pond located in Outlot A as proposed by City Water Resource staff. • To recommend that the applicant reroute the proposed water main installation to avoid impact to Outlot B. • To require that the applicant submit a revised Tree Preservation Plan and revised Tree Mitigation Plan following adoption of staffs' recommendations. • To require that Tree Protective measures (i.e. orange colored silt fence or 4 foot polyethylene laminate safety netting) be installed at the Drip Line or at the perimeter of the Critical Root Zone, whichever is greater, of significant trees/woodlands to be preserved. • To require that the applicant contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. 6. An on-site pond be constructed in the northwest corner of the site to provide on-site treatment for runoff from this parcel. The pond excavation should incorporate a 10-foot wide aquatic bench extending from NWL to 1 foot below NWL and side slopes below the aquatic bench should be 3:1 to a maximum depth of 4 feet.

MEMO city of eagan TO: ADVISORY PARKS COMMISSION FROM: BOB KIRMIS, PLANNER DATE: FEBRUARY 5, 1999 SUBJECT: MANLEY BROTHERS CONSTRUCTION - REZONING/PRELIMINARY SUBDIVISION (OAK BLUFF ESTATES) BACKGROUND Manley Brothers Construction is requesting preliminary subdivision approval to allow the creation of a 36 lot single family residential subdivision located east of Dodd Road and north of Diffley Road. In conjunction with the requested preliminary subdivision, the applicant has also requested a rezoning of the property from an A, Agriculture to an R-1, Residential Single Family zoning designation. The subject 16.4 acre property slopes downward from west to east with the most significant topography being located along the site's eastern boundary. Numerous significant trees exist along the eastern boundary of the site, the vast majority of which are to remain. The subdivision is proposed to be accessed via three points from Dodd Road and includes a private road segment (cul-de-sac) in the southern portion of the site. This item is scheduled for consideration at the forthcoming February 23 APC Meeting. PARKS/TRAILS DEDICATION This development would be subject to a cash parks dedication and a cash trails dedication. TREE PRESERVATION This 14-acre site is located north of Diffley Road on the east side of Dodd Road in the SW '/4 of Section 24. Dwellings on the site currently include one farm site with a large storage shed and two single-family residences. The east boundary of this site is wooded and slopes down considerably to existing single family residences. Significant Vegetation A tree inventory has been submitted for this site. It indicates that there are 35 significant trees on site. Tree species include 21 oaks (6" to 40" diameter), 5 spruce (20' to 25' height), 3 pine (25' height), 2 ash (13" and 17" diameter), 3 elm (16" diameter each), and I silver maple (24" diameter). Lik There are also 847,315 square feet of significant woodlands on this site. All of these woodlands are located on the east half of the site, most of them on slopes dropping to the east or in ravines. Development of this site as proposed will result in the removal of 14 significant trees (40% of the total) and in the removal of 48,497 square feet of significant woodlands (5.7% of the total). According to the City of Eagan Tree Preservation Ordinance allowable removal for this type of development, (multiple-lot single-phase single-unit residential) is set at 40%. With a significant tree removal equal to or less than allowable limits there is no tree mitigation required for this development. Additional Concerns There are five large bur oak trees located in Lots 20, 21, and 22 of this development. Tree numbers and associated diameters of these trees are as follows: #1 30" diameter (wind related crown damage) #2 30" diameter (wind related crown damage) #3 30" diameter #4 20" diameter #5 40" diameter According to Tree Preservation Ordinance definitions any oak tree 30" and larger is considered a Specimen Tree. Preservation of these unique trees is highly recommended. Lot 22 contains three of these large oaks (#3, #4, and #5). The submitted plan indicates that the proposed house pad will be within twenty feet of the trunk of all of these trees. Eagan's standard tree protection requirements states that tree protection areas shall be set up at a distance of one foot per one inch trunk diameter of trees to be preserved. The submitted plan does not allow for this. In order to allow for sufficient distance between preserved trees and construction activities, staff is recommending that lot lines for Lots 19, 20, 21, and 22 be shifted 20 feet to the east. This will shift will allow sufficient root protection area to increase chances of long-term survival of these specimen oaks. Recommendation To recommend that a revised plan be submitted that shifts the lot line locations of Lots 19, 20, 21, and 22 twenty feet to the east. To require that the applicant contact the City Forestry Division upon the installation of the required mitigation for inspection to ensure compliance with the approved Tree Preservation Plan and Mitigation Schedule. To acknowledge that Individual Lot Tree Preservation Plans will be required at the time of building permit application for lots 19, 20, 21, and 22. WATER QUALITY/WETLANDS This development is located within the watershed of Fish Lake, a Class I direct contact recreation water body. Runoff from the site will be discharged first to Pond JP-22, a 0.4-acre pond designated as a stormwater basin in the City's water quality management plan. Pond JP-22 in turn discharges through a series of several ponds and lakes and then via a lift station to Fish Lake. Staff recommends on-site ponding to treat this runoff prior to discharge to Pond JP-22 and then to Fish Lake. The development parcel is very hilly, with a topographic difference of over 90 feet from the southwestern corner to the northeastern portion of the property. The grading plan shows two stormwater ponding areas constructed in the north-central portion of the site to treat runoff from this development. The excavation should be conducted to include a 10 foot wide safety bench just below the normal water elevation and that the side slope below the bench not exceed 3:1. The ponds should have a combined minimum wet volume of .5 acre-feet. A cash dedication in lieu of onsite ponding for graded areas not treated by proposed ponding areas is recommended. There are no jurisdictional wetlands within the development parcel. Staff recommends that: • On-site ponding be constructed in the northwest corner of the site to provide on-site treatment for runoff from this parcel. The ponding excavation should incorporate a 10-foot wide aquatic bench extending from NWL to 1 foot below NWL and side slopes below the aquatic bench should be 4:1 to a maximum depth of 4 feet. The ponding should have a minimum wet volume of 0.5 acre-feet • A cash dedication in lieu of on-site ponding be required for the graded areas in the development not treated by the proposed ponding. FOR COMMISSION CONSIDERATION 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication. 3. Recommend that a revised plan be submitted that shifts the lot line locations of Lots 19, 20, 21, and 22 twenty feet to the east. 4. To require that the applicant contact the City Forestry Division upon the installation of the required mitigation for inspection to ensure compliance with the approved Tree Preservation Plan and Mitigation Schedule. 5. Individual Lot Tree Preservation Plans will be required at the time of building permit application for lots 19, 20, 21, and 22. 6. On-site ponding be constructed in the northwest corner of the site to provide on-site treatment for runoff from this parcel. The ponding excavation should incorporate a 10-foot wide aquatic bench extending from NWL to 1 foot below NWL and side slopes below the aquatic bench should be 4:1 to a maximum depth of 4 feet. The ponding should have a minimum wet volume of 0.5 acre-feet 7. A cash dedication in lieu of on-site ponding be required for the graded areas in the development not treated by the proposed ponding. yj O4JC SL L ISTE4TE8 ' a..E6' 00'778 AlLeoa we Prellmi.arfay - E,.

This was to include a method for identification and potential for acquisition. The sub-committee met on Tuesday January 26 to begin that process. MEETING DISCUSSION: The Committee discussed what the goals of the Commission should be relative to the need and importance of identification of open space parcels. It was the group's consensus that review of open space should be limited to parcels that add value to the park system rather than just open, undeveloped land to be saved from development. To that end, the group felt that the first steps were to identify potential parcels, or portions of parcels, that: 1. Would be adjacent to existing park property and could be used to enhance the park's function. 2. Would be property adjacent to lakeshore. 3. Would provide critical trail connections. 4. Would contain mature woodlands. Two examples identified were: 1. Thomas Lake Park - West shoreline of Thomas Lake. Located in the SW quarter of section 28, north of Cliff Road and East of Thomas Lake Road. Although not a critical trail linkage, this wooded lakeshore parcel would greatly complement Thomas Lake Park. 2. Patrick Eagan Park - North shoreline of a pond Located in the SE quarter of section 22. This is a critical trail linkage that is currently privately owned. Without this important link, the access to the western portion of Patrick Eagan is diminished considerably. If this link is not obtained, a pedestrian bridge would likely be necessary to be able to have a trail encircle the lake. OTHER STEPS/FUNDING The sub-committee also discussed the importance of meeting with the City Council to discuss this process. Prioritizing parcels that were identified along with funding was also discussed. L7 It was the group's decision that before proceeding with the task, the entire Commission should be in agreement with the four "criteria" noted above for property identification. Because there is now a "new" Commission, there may be a different group identified as the Acquisition/Development sub-committee. FOR COMMISSION ACTION: Review the work of the sub-committee, make appropriate changes and approve/disapprove moving ahead with the process of property identification. CITY OF EAGAN MEMO TO: Park Advisory Commission FROM: Ken Vraa, Director of Parks and Recreation Paul Olson, Superintendent of Parks DATE: February 3, 1999 SUBJECT: Dakota Hills Middle School Maintenance Agreement Background: The City has a long history of providing assistance to the local schools with those functions or projects determined to be of value or benefit to the community. Examples include playground installation and general field maintenance, which are used by area residents. The assistance has generally been provided at no cost to the school other than the cost of materials. In most instances the materials have been ordered directly by the school making the request. In April of 1997, the city entered into a two-year agreement with School District #196 for the provision of additional maintenance service levels on the athletic fields located at Dakota Hills Middle School. The four baseball fields and one football/soccer field are important components of both school and athletic association sponsored athletic activities. The school administration and subsequently the City agreed that the athletic programs and thus the community would benefit from an increased level of field maintenance. The district, however, was lacking the manpower and equipment necessary to take the fields to the next "level" of quality. Two year Agreement: The primary focus of the original agreement was the improvement of turf and infield surface. Staff from the Park and Recreation Department agreed to include the Dakota Hills athletic site in the established park maintenance program and include it when scheduling maintenance activities. Basic elements included: • Grading and enhancement of the infield surfaces in the spring and summer. • Regular mowing and trimming of the field areas throughout the growing season. • Fertilization and aeration of field area. • Other enhancements or repairs as necessary. The school in return agreed to reimburse the City for the cost of materials, manpower and equipment at the hourly rates established in the City Fee Schedule. The Park Commission and subsequently the City Council agreed to enter into the agreement on a 2-year trial basis, with the intent of re-visiting the issue at the conclusion of the two-year period. L+v\ We are pleased to report that the agreement has been a resounding success. Both the school and athletic associations have noticed an obvious improvement in the quality of the turf and infields. The Park Maintenance Division has successfully incorporated the site into existing maintenance "routes" with minimal impact on scheduling or quality. On several occasions it became necessary to utilize overtime hours, however, the costs to the City were recouped. The following is a summary of hours / billings for the first 2 years: Time Spent Total Billing (All Costs) _99- A 180 Man hours $12,222 1998 250 Man hours $13,745 Total 430 Man hours $25,967 Ave. @ yr. 215 Man hours $12,983 Renewal of agreement: Department staff recently met with the school administrators to review the agreement and to hear their opinion of the success of the program. The administration of Dakota Hills Middle School has proposed that the agreement be renewed for another 2 years. The only modification would be the hourly rates for equipment and manpower as approved annually in the City Fee Schedule and the inflationary cost of materials. Other Considerations / Discussion Staff is always concerned with the obvious limit to resources that the city has. This is the same concern that is shared for the limited number of fields available for play in the community. In this situation, the need for both the number and the level of quality for the fields far outweigh the concern for utilization of maintenance staff. And, given that the city is reimbursed for the assignment of staff to this work, there is even more reason to proceed with another two-year agreement. The commission should also be aware that following the January commission meeting in regards to the draft agreement with Faithful Shepherd Catholic school, city staff is responding their request to consider a similar approach to this schools fields. For Commission Action: The Commission should review the issue and a make a recommendation to approve or deny a new two-year agreement for maintenance agreement. K. Vraa, Director of Parks & Recreation I : fang l \dakotahil is .03 3 5L ADVISORY PARKS COMMISSION EAGAN, MINNESOTA MINUTES OF REGULAR MEETING OF JANUARY 14, 1999 A regular meeting of the Advisory Parks Commission was called to order at 7:00 p.m. on January 14, 1999 with the following Commission Members present: Terry Davis, Jerry Farlee, Barbara Johnson, Bonnie Karson, George Kubik, Lee Markell, Daryle Petersen, John Rudolph and Michael Vincent.

Advisory Parks Commission Minutes of Regular Meeting of January 14, 1999 Page 2 • Skimmers of suitable design to the City shall be installed on the outlet of all detention basins and the discharge pipes from the detention basins should be extended to the NWL of Pond EP-7. • An undisturbed and unmaintained buffer extending at least 30 feet back from the delineated boundary of any wetlands shall be preserved. • Depressional area in the southwestern portion of the parcel needs to be evaluated for possible wetland and no filling or draining of any wetlands shall be done. 2. Hittner Addition - Keith Hittner • This development shall be responsible for a cash parks dedicaiton and a cash trails dedication. • Individual Lot Tree Preservation Plans will be required at the time of building permit application for Lots 1, 3, 4 and 5. • This development shall be responsible for a cash dedication of approximately $1,300-1,450 based on the area and impervious characteristics of developed lots in lieu of on-site ponding. • An undisturbed and unmaintained buffer extending at least 30 feet back from the delineated boundary of both wetlands shall be preserved. Grading on Lot 5 should be done so as not to encroach on this buffer. 3. Windsor Estates - Hartford Financial Services • This development shall be responsible for a cash parks dedication and a cash trails dedication. • The Tree Preservation Plan shall be approved as submitted with the following conditions: • To require that Tree Protective measures (i.e. orange colored silt fence or 4 foot polyethylene laminate safety netting) be installed at the Drip Line or at the perimeter of the Critical Root Zone3, whichever is greater, of significant trees/woodlands to be preserved. • To require that the applicant contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. • To require that the applicant install 79 Category B trees and 15 Category C trees as mitigation for significant tree/woodland removal in excess of allowable limits. • To require that the applicant contact the City Forestry Division upon the installation of the required mitigation for inspection to ensure compliance with the approve Tree Preservation Plan and Mitigation Schedule. 4. An on-site pond shall be constructed in the northwest comer of the site to provide on-site treatment for runoff from this parcel. The pond excavation should incorporate a 10-foot wide aquatic bench extending from NWL to foot below NWL and side slopes below the aquatic bench should be 4:1 to a maximum depth of 4 feet. The pond should have a minimum wet volume of 0.55 acre-feet. 5. An undisturbed and unmaintained buffer extending at least 30 feet back from the delineated boundary of the wetland shall be preserved. DEVELOPMENT PROPOSALS There were no development proposals for the Commission to review. Advisory Parks Commission Minutes of Regular Meeting of January 14, 1999 Page 3 OLD BUSINESS FAITHFUL SHEPHERD SCHOOL DRAFT AGREEMENT Director Vraa noted that the Commission has previously reviewed this issue as part of the Faithful Shepherd development proposal. The school has asked that an agreement similar to the one between the City and Dakota Hills Middle School be considered for the field use at Faithful Shepherd School. He also noted that although both parties have reviewed this agreement, the City's attorney has not yet reviewed the document. Vraa noted that the agreement presented is for a length of 15 years. Should the school expand it would most likely do so over one of the athletic fields, thereby eliminating the field's availability. The school has agreed that if that should happen they would pay the City a portion of the proposed park dedicated fee amortized over the 15 year period. It was noted that the dedication fee for this development would be approximately $110-115,000. The changes the City has made to the agreement include language regarding specifics of fertilization, aeration and maintenance, Vraa added. Mr. Chuck Hall, representing the school, explained that the trails had not been discussed as part of this agreement since it would need to incorporate several contiguous property owners. He also noted that field lighting has not been discussed as yet but service is being provided to the site, along with a meter, in the event the City wishes to add field lighting at a later date. The use can then be monitored through the meter. He thanked the Commission for their involvement and input with this development. Member Markell asked what would happen after the 15 year term of the agreement. Director Vraa responded that the agreement would be null and void at that time but that a new agreement may be negotiated at that time. Mr. Hall added that they wanted a sunshine clause in the agreement because they foresee the expansion of this school before the end of the 15-year agreement necessitating the loss of what is now the soccer field. He clarified that if they did expand on the soccer field (1/3 of the current field space) they would pay a portion of the amortizied park dedication fee. Member Petersen stated he did not see a 15 year tern identified in the agreement. He also wanted to see an exhibit that would identify what the amortized amount would be if only one field were lost. Member Vincent suggested that a clause should be included that states this is not a partnership with an agreement to hold each other harmless in case of litigation. Member Markell recapped commission comments by stating that this agreement is basically in lieu of parks dedication fees and the agreement allows the City the use of 3 fields for 15 years. Any loss of fields prior to the 15 year term will be responsible for a pro-rated parks dedication fee. Michael Vincent moved, Daryle Petersen seconded with all members voting in favor to direct staff to proceed with the agreement negotiations based on the discussion of this meeting. .NEW BUSINESS SET FEBRUARY MEETING DATE The Commission selected the date of Thursday, February 11, 1999 for their regular February meeting.
