Staff felt that It might be easier for this area to be seen prior to the leafing out of the vegetation on the site. This site visit is for the Acquisition and Development subcommittee, but as always, if others from the Commission would like to come along you are welcome. If you would like a ride, please meet at City Hall (east side) at 6:25 p.m. or you can proceed directly to the site on your own and we will meet you there. Mr. Ron Rasmussen, President of the Eagan Athletic Association has been invited to attend this meeting to provide information on the Association's activities. The Commission had previously asked for an update on how the Association was doing and this should provide that opportunity. In response to a letter from the Director of Parks and Recreation, Ron has provided staff with a list of short and near term needs so the Department's maintenance division can prioritize Its work program to take care of these identified tasks. The letter Is attached at the back of the packet. Department Happenings Recently, the Forestry Division received recognition from the National Arbor Day Foundation for being named a "Tree City". This award will be presented to the Commission as the first Item under Department Happenings. Consent There are three items on the Consent Agenda. Unless a Commission Member would like to pull one of the items for discussion, a motion to approve would be In order. Development Proposals Two development proposals are to be reviewed with separate memos prepared for each. In light of the workshop discussion on Tuesday, April 8 regarding additional acquisition of property adjacent to the Blackhawk Park entrance road, members may want to visit the park site on their own prior to the meeting. This may help your discussion relative to the Springbrook proposal for the Murphy farm. The second proposal Is for the Eagandale Corporate Center No. 2, formally known as the Dart property. Old Business The single item under Old Business Is Community Parks Signs. At the last Commission meeting, some concern was expressed regarding redwood being used to construct the signs. Staff has done additional research on this and will review possible, alternatives. The remaining Items on the agenda are to be presented verbally. Please keep In mind that this is the meeting where the Commission picks the winner of the annual poster contest. This poster contest is held annually for the third graders in Eagan elementary schools as part of the National Arbor Day celebration. The Commission usually completes this fun task after the regular meeting has adjourned.

In 1996, Eagan certified 327 coaches through the National Youth Sports Coaches Association program. Only the City of St. Paul, with 336, had more. Support from the Eagan Athletic Association is vital to this program. 2. Staff are in the midst of NYSCA clinics for EAA spring/summer sports. With two dates to go, 131 coaches have taken part. 3. Sixty two persons took part in the 55/Alive Mature Driving seminars. Completion of the program results in heightened awareness of driving safety concerns for persons ae 50 or older and a 10% reduction in insurance premium costs. 4. The Department's tree and gardening seminars were enthusiastically received by participants. Gregg Hove and Diana Bolander were superb presenters. 5. The Department received a request for an interpreter for the April 5 NYSCA clinic. Interpretation was difficult in a darkened room, plus the rapid fire presentation on the tape. Staff will look into the availability of closed captioned videos from NYSCA, although none have been advertised in the NYSCA literature. 6. Ballfield allocations have been made for EAA soccer, baseball and softball. Baseball and softball, with registrations down somewhat, are in excellent shape. Soccer field configurations are changed from last summer. The availability of Lexington/Diffley allows for flexibility. Despite providing more field space than a year ago, soccer fields at Quarry, Bridle Ridge and Mueller Farm Parks are being requested. 7. Staff will be getting the Northview concession room ready for the season during the week of April 21. Temperatures are too cold as yet to turn on the water in the building! 8. Spring break recreational activities were a resounding success. All activities filled, sections were added and summer seasonal staff were rushed into service. It would be interesting to know whether mailing of the brochure had an impact. The level of participation was higher than in previous years. 9. All Evening in the Park events are booked. McDonald's of Eagan is paying for the Ronald McDonald Show, which enables seven evenings of entertainment to be offered. 10. "Augies" band will play for the seniors group again. Old time concertina/accordion music is of particular favor to the seniors. 11. The annual tree sale is scheduled for Saturday, April 26, at the Public Works Maintenance Building. Over 600 requests for nearly 1,200 trees were received by the deadline. Space and logistics limit the number of trees available to 800. A "lottery" system is used to select the requests that are filled. 12. The annual Arbor Day celebration is scheduled for Saturday, May 3, at Blackhawk Park. 13. Staff is nearing completion of trail sweeping throughout the City. Nearly 90 miles of trail and pathway are included. The heavy accumulation of sand along county roads has slowed the operation and taken a toll on equipment. The County will be removing the sand from the boulevards. 14. The recent severe cold weather has refrozen the ballfields delaying infield grading. Staff will resume grading as soon as conditions allow. 15. Staff has completed construction of two batting tunnels to be installed at Dakota Hills Middle School. The materials are being purchased by EAA and the School District. 16. Aeration pumps and baffles have been removed from all ponds and lakes. 17. A polymer coated fertilizer will again be used on park sites and athletic fields. The coating serves to "time" the release of the nutrients and eliminates offensive dust. Soil tests conducted at several sites have shown a need for little or no phosphorus. 18. The inspection of playgrounds throughout the system has begun. The replacement of worn plastic slides is becoming necessary at several sites. Slides can cost from $1,500 to $2,000. 19. Staff has completed the construction and installation of the new entrance signs at Lexington Diffley Athletic Fields. 20. An agreement to share in the purchase of a power top dressing unit with the City of Inver Grove Heights was recently finalized. Because of the limited use of a top dressing unit, neither City could justify allocating funds equivalent to the cost of a new unit. Staff is studying the status of other pieces of equipment to identify possible shared purchases. 21. Groups or individuals who are interested in taking part in the 4-Your-Parks clean-up program sponsored by WCCO and the Minnesota Recreation and Park Association can register and obtain additional information by calling 681-4300. 22. 249 adult slo-pitch softball, teams are registered to play in Eagan this year. 32 schedules have been created for a total of over 1,800 games spread out April 27 through August 8. Northview Athletic and Lexington-Diffley Athletic fields will be utilized Sunday through Friday evenings. 23. The front porch at Holz Farm has been removed for reconstruction through dollars provided by the Knights of Columbus. they are also funding the installation of a handicapped ramp and the painting of the barn. 24. Jensen's Supper Club raised a total of $865 for the Friends of the Farm during the month of February. 25. Eagan's Earth Day Celebration will be Sunday, April 20 from 12:00 to 3:00 p.m. at Blackhawk Park. A walk, lunch, displays and demonstrations are planned all at no charge! Composting, carpooling, crafts, paper-making, recycling, smart shopping, landscaping, water quality and many other topics are included. Prizes, too! 26. Over 1,000 letters were sent out to residents in sensitive watershed areas of Carlson Lake, Manor Lake, Schwanz Lake, and Bur Oak Pond in late March soliciting cooperation in reducing pollutant loads to these water bodies. 27. In a cooperative effort with the Department of Public Works Streets Maintenance Division, staff tested the use of regenerative air sweepers operating in tandem with mechanical sweepers to clean streets in the direct drainage areas of Carlson Lake, Manor Lake, LeMay Lake, Hay Lake, and Pond JP-23. Air sweepers are significantly more effective in picking up the fine particles which carry most of the particulate phosphorus load in street runoff. The cost-effectiveness of this method of street sweeping for environmental purposes is being evaluated by staff. 28.

The site is located north of Opperman Drive and east of Highway 149 In the NE '/a of Section 13. The site is zoned PD-Planned Development and 1-1 Limited Industrial and the Cities Comprehensive Guide Plan designates this area as IND-Limited Industrial. The purpose of combining the lots Into one lot is so that UPS may add the second phase of its building. At some time In the future (5-10 years) it is UPS's intention to add a 254,542 s.f. building addition. UPS 1st Addition was originally subdivided in 1985 after purchasing approximately 84 acres from the Gopher Smelting Co. The building has been in operation since 1986. PARKS/TRAILS DEDICATION This development will be responsible for a cash parks dedication as well as a cash trails dedication. TREE PRESERVATION There is no significant vegetation on this site. WATER QUALITY/WETLANDS This development is an addition to an existing development in drainage basin G. The additional development will generate storm water runoff that will discharge to an existing large on-site pond designated Pond GP-5. The pond does not currently have an outlet and no outlet will be installed as a result of this development. Thus, all runoff will be contained on the site. There are no jurisdictional wetlands within the site. Staff recommend that this development discharge all runoff from the development to existing Pond GP-5, and that no outlet be installed in Pond GP-5 so that runoff is contained entirely on-site. 5. RECOMMENDATIONS 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication. 3. This development shall discharge all runoff from the development to existing Pond GP-5, and no outlet shall be installed in Pond GP-5 so that runoff is contained entirely on-site. ,i' _ '171 I ? • _ y Ifs I - D j is i % _ t .M.~ i L RRR• I I-,- t •r FI j ` r•rs.rw--~ wRrR.Iru ~-r-- "T" Ye 84 r eel } ~lFi =~Fg i! j 6 r I pppp = iFFj=I=i' ¦ ~ I ~ C UPS y ~ppI/A&.

Tesseract school was built in 1988 and Is located south of Silver Bell Road north of Highway 13 and east of Tesseract Place In the NE '/4 of Section 19. The school Is zoned Planned Development and the City's Comprehensive Guide Plan designates this area as IND- Industrial. As proposed, the plan Increases the land area from three acres to six acres. In addition to the proposed 15,000 s.f building expansion, the school is proposing to add a drop off/pick up area and 66 new parking stalls. PARKS/TRAILS DEDICATION This development shall be responsible for a cash parks dedication and a cash trails dedication for the additional acreage acquired for the expansion of Tesseract School. TREE PRESERVATION The submitted tree Inventory Indicates that there are three significant trees on site; two 12" cottonwoods, and a 15 Inch cottonwood. All three of these trees will be removed during site development. The remainder of the vegetation on site is small diameter softwood deciduous trees (cottonwood, elm, Russian olive), which are scattered over the southerly portion of the site. Most of this smaller diameter vegetaion will be preserved as a buffer from Highway 13. According to the City of Eagan Tree Preservation Ordinance, allowable removal of this type of development (commercial, single lot) Is set at 30% of the existing significant vegetation. The applicant proposes to remove 100% of the significant vegetation, however only three trees are Involved. Mitigation for tree removal In excess of allowable limits calculated to two Category A trees or four Category B trees or 8 Category C trees. As mitigation, the applicant will be transplanting seven 3 Inch and 4 Inch hardwood deciduous trees from construction areas on site to areas where the trees will be preserved. If . WATER QUALITY/WETLANDS Water quality and wetlands. This site generates runoff that discharges to a storm trunk line along Nicols Road that In turn discharges to an open channel adjacent to the Nicols Fen. This channel Is eroding badly because of wide fluctuations in storm water flows. The proposed expansion of the building and parking lot will increase Impervious coverage of the 4.2 acres of the site within the grading limits from 40% to approximately 70%. To deal with storm sewer capacity problems downstream and to prevent exacerbation of channel erosion problems adjacent to the fen, staff recommends that a pond be constructed on the site. With some slight design modifications to enhance safety, the proposed pond will meet the water quality mitigation requirements for this development. There are no jurisdictional wetlands within the site. Staff recommends that water quality mitigation requirements for the development be met through on-site ponding. RECOMMENDATIONS 1. This development shall be responsible for a cash parks dedication for the additional acreage acquired for the expansion of Tesseract School. 2. This development shall be responsible for a cash trails dedication. 3. The Tree Preservation Plan should be approved as proposed with the following conditions: • At least two Category A trees (4 inch dbh) trees shall be transplanted on site as mitigation for excessive tree removal. 4. Water quality mitigation for this development shall be met through on-site ponding. i i Preliminary Plot of: \ a..,.._ I _ L~ (~.....I I I I TESSERACT ADDITION i s . l Y 4 ~?o~i-.IFn SILVER BELL ROAD a \ c - - = MWSSM - - - - ` n I • I 1 • t~~l....- w r - uw rw d rl . iW • (1~._ 4 w•~M i Y w .ti.(j 1T ` • • ~ • : C.- 4. fr rr .•q a.~. .rw ! fit' • . ...wra: V.ltirwrw....a....r $ ; I • .

The site is located In the northwest '/4 of Section 32. The three proposed lots range from one acre to 2.93 acres In size. Proposed Lot 1 adds 90 feet to the southwest of existing Lot 1, is 2.93 acres In size, and contains the existing Park Nicollet medical clinic. Proposed Lot 2 Is 1.96 acres in size, on which the applicant proposes to construct a two-story, 24,000 square foot office building southwest of the existing medical clinic. Proposed Outlot A Is one acre in size and is located at the southwest end of the property. In 1988, a Planned Development was approved for this property which provided for Limited Business uses. Since office buildings are a permitted use in the LB district, the proposed office building for Lot 2 is consistent with the previous Planned Development approval. The proposed subdivision will allow for a future expansion of the Park Nicollet medical clinic by enlarging that parcel 90 feet to the southwest. Regarding the new office building proposed for Lot 2, the building is proposed to be a brick two-story office building located at the southwest edge of the site. Parking Is located to the northeast of the building, and adjacent to 1-35E. A single driveway access is provided to Plaza Drive and a monument sign located south of the driveway. Grading is proposed to encompass the entire site Including Lot 2 (for the proposed office building, and portions of Lot I (Park Nicollet expansion area) and Outlot A (remaining vacant). PARKS/TRAILS DEDICATION This development shall be responsible for a cash parks dedication and a cash trails dedication. TREE PRESERVATION There Is no significant vegetation on this site. WATER QUALITY/WETLANDS This development would generate runoff that will discharge to Pond AP- 14, a designated sediment basin. Runoff from the site will eventually reach Cliff Lake, an indirect contact recreation water body, after it passes through two more treatment basins. Because of the relatively small size of the development and the number of treatment basins between the development and the nearest downstream recreational water body, staff recommends a water quality cash dedication for this development. There are no jurisdictional wetlands within this development. Staff recommend that the water quality mitigation requirements be met through payment of a cash dedication. RECOMMENDATIONS 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication. 3. There is no significant vegetation on this site. 4. The water quality mitigation requirements shall be met through payment of a cash dedication. IM c7j ~f~~~ ~ cal LIJ YYY Y YtB, t w LL - y\ T ` \ i.

This development shall be subject to a land dedication of Outlot A and Outlot B which will fulfill the parks dedication for the 22 acre site currently proposed and the remaining 13.5 acres not proposed for development at this time. 2. This 22 acre development shall be responsible for a cash trails dedication. 3. The Tree Preservation Plan shall be approved as proposed with the following conditions: • The applicant shall install 7 Category B trees as mitigation for significant tree removal in excess of allowable limits. • The applicant shall comply with the prepared grading and site reclamation conditions resulting from encroachment into Blackhawk Park. • The applicant shall create and implement a Conservation Easement protecting the significant woodland located in Lots 15 through 19 of Block 2. 4. The applicant shall revise their landscape plan as follows: • A portion of the proposed screen planting stock should be shifted to the area behind Lots 12 through 19 of Block 2 to protect a soft buffer edge between the residential lots and Blackhawk Park. Screen planting species I these areas should include only those species which are native to the Blackhawk Park area. Acceptable species include oak, ash, birch, black cherry, elm, and red cedar trees. • Boulevard planting locations should be revised and changed from the formal, evenly spaced pattern to a more natural, clustered pattern which strategically places vegetation in areas that will both benefit the future residences (i.e. screen headlights) and will also provide more optimal growing conditions for the installed plant material. 5. Tree Protective measures (i.e. 4 foot polyethylene laminate safety netting) shall 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. 6. The applicant shall 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. 7. Water quality mitigation requirements shall be met through construction of on-site ponding. Skimmers should be installed on both pond outlets and the design of the ponds must be approved by the water resources coordinator. 8. The jurisdictional status of the low area in the northeastern corner of the site should be determined when field conditions permit. If the area is determined to contain a wetland, no draining or filling of the wetland is allowed. city of eagan MEMO TO: Advisory Parks, Recreation and Natural Resources Commission FROM: Ken Vraa, Director of Parks and Recreation DATE: April 7, 1997 RE: Springbrook Corporation - Murphy Farm BACKGROUND Springbrook Corporation Is requesting a Rezoning and Preliminary Subdivision ( Murphy Farm) on 22 acres located at the northwest corner of the Intersection of Deerwood Drive and Murphy Parkway. The proposed rezoning Is from Agricultural to R- 1 Single Family and Is compatible with the Comprehensive Guide Plan. The proposed preliminary subdivision consists of 38 lots for single family development. Access will be provided by a new road off Murphy Parkway and a connection to Davenport Avenue to the west. The proposed preliminary subdivision meets all code requirements regarding lot area and setbacks. PARKS/TRAILS DEDICATION In the early 1990's, staff had negotiated with the property owner (Leo Murphy) for an "early dedication" of park land. This early dedication was for the purpose of constructing the south access road into the park from Murphy Parkway. The early dedication amounted to .664 acres. Under the terms of the agreement, this early dedication would be credited towards any future dedication requirements. The Springbrook proposal intends to develop approximately 22 acres of the Murphy property. The applicant is proposing a park dedication consisting of 2.85 acres of land flanking the entrance road to Blackhawk Park. A park dedication credit of 0.7 acres will be granted for a portion of land used for the park road. The total proposed park dedication of 3.55 acres satisfies the dedication requirements for this 22 acre site and the remaining 13.5 acres of the Murphy property which Is not proposed for development at this time. The City has previously Identified Outiot B as an Important addition to the park through land dedication. Outiot A also adds to the park In terms of It's value and Is deemed an appropriate land dedication. It would be appropriate to recognize that the park land dedication exceeds what would be required for this development and that the credit should carry towards future development of the remainder of the Murphy property. As It relates to trails, it would be appropriate for this development to make a cash trails dedication. TREE PRESERVATION The submitted tree inventory Indicates that there are 213,445 square feet (4.9 acres) of significant woodlands located on this site. Two separate woodlands comprise this total wooded area, one woodland Is located in the southeast are of this development site (this entire woodland will be removed during site development), and the other woodland is located in the northeast part of this site, adjacent to the Blackhawk Park entrance road (this entire woodland will be preserved throughout site development). These woodlands are comprised of a variety of deciduous trees (6" to 18" diameter range). According to the City of Eagan Tree Preservation Ordinance allowable removal for this type of development (mulitpie lot, single family residential) is set at 40% of the existing significant vegetation (85,378 square feet). The development as proposed will result In the removal of 87,120 square feet (40.8%) of the significant vegetation. Mitigation for the removal of significant vegetation In excess of allowable limits calculates to three Category B trees (2 Y2 diameter deciduous trees or 6 foot coniferous trees). Mitigation for the removal of significant vegetation in excess of allowable limits will be accomplished through the installation of plant material as Indicated on the submitted Preliminary Landscape Plan. Encroachment Into Blackhawk Park Site development in the area of the proposed Donegal Way will result in grading operation that encroaches approximately 120 feet into Blackhawk park. The applicant is making this grading request In order to have a finished product that will result In a more "natural landform", versus having to utilize sharp grade changes and the installation of retaining walls at the edge of park property. Staff has met with the applicant at this site to determine proposed grade limits. The applicant will be responsible for grading and site reclamation of grading areas Into the park property. Grading into the park property will proceed as follows: 1. top soil will be removed and stockpiled, 2. site grading will take place and will result in smooth contours replicating natural conditions, and then the 3. top soil will be replaced. 4. Disturbed areas will be seeded with a native grass mixture consistent with specifications provided by City staff. 5. Steep areas, where erosion is possible, will receive appropriate erosion control measures. The required conditions outlined above will be Included for review and approval within the development contract at the time of final plat approval. Conservation Easement - Wooded Area Adiacent to Blackhawk Park Staff is recommending that the applicant establish a Conservation Easement for the wooded area on the hillside behind lots 14 through 19 of Block 2. This natural wooded area Is currently, and will hopefully serve in the future as a soft buffer between the backs of the residential units on these lots and Blackhawk park itself. This area of the proposed development is in direct view from the park shelter building and parking lot area. The created conservation easement should state that no removal of vegetation (overstory and understory) can take place within conservation easement areas. Landscape Plan - Boulevard Trees and Screen Plantings Staff Is recommending that the submitted landscape plan be revised and resubmitted as follows: 1. A portion of the proposed screen planting stock be shifted to the area behind Lots 12 through 19 of Block 2 to provide a soft buffer edge between the residential lots. Screen planting species In these areas should Include only those species that are native to the Blackhawk Park area. Acceptable species Include oak, ash, birch, black cherry, elm, and red cedar trees. 2. Boulevard planting locations be revised from the formal, evenly spaced pattern to a more natural, clustered pattern which strategically places vegetation In areas that will both more benefit the future residences (i.e. to screen headlights) and will also provide more optimal growing conditions for the Installed plant material. WATER QUALITY/WETLANDS This development will generate runoff that discharges to two different major drainage basins. The north half of the site will drain toward Blackhawk Park and eventually into Blackhawk Lake, while the southern half of the site will discharge runoff that will eventually reach Langhoven Pond in Woodhaven Park. On-site ponding Is both feasible and desirable, so wet ponds have been Incorporated Into the development to treat runoff adequately before discharge off-site. Staff recommends that the pond in the southeast corner of the site be reduced in wet volume from 1.27 AF to 1 AF to assure that it retains a standing pool of water during dry conditions. A wetland survey for the site was conducted and identified one potential jurisdictional wetland In the far northeastern corner of the site adjacent to the Blackhawk Park entrance road. Since soils were frozen and vegetative Indicators scarce at the time of the initial survey, this area will need to be Investigated in the field later this spring to determine Its jurisdictional status. The current grading plan shows no grading In this area. RECOMMENDATIONS: 1. This development shall be subject to a land dedication of Oudot A and Oudot B which will fulfill the parks dedication for the 22 acre site currently proposed and the remaining 13.5 acres not proposed for development at this time. 2. This 22 acre development shall be responsible for a cash trails dedication. 3. The Tree Preservation Plan shall be approved as proposed with the following conditions: • The applicant shall Install 7 Category B trees as mitigation for significant tree removal In excess of allow limits. • The applicant shall comply with the prepared grading and site reclamation conditions resulting from encroachment Into Blackhawk Park. • The applicant shall create and implement a Conservation Easement protecting the significant woodland located in Lots 15 through 19 of Block 2. 4. The applicant shall revise their landscape plan as follows: • A portion of the proposed screen planting stock should be shifted to the area behind Lots 12 through 19 of Block 2 to protect a soft buffer edge between the residential lots and Blackhawk Park. Screen planting species in these areas should include only those species which are native to the Blackhawk Park area. Acceptable species Include oak, ash, birch, black cherry, elm, and red cedar trees. • Boulevard planting locations should be revised and changed from the formal, envenly spaced pattern to a more natural, clustered pattern which strategically places vegetation In areas that will both benefit the future residences (i.e. screen headlights) and will also provide more optimal growing conditions for the Installed plant material. Oi? 5. Tree Protective measures (i.e. 4 foot polyethylene laminate safety netting) shall 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. 6. The applicant shall 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. 7. Water quality mitigation requirements should be met through construction of on-site ponding. Skimmers should be installed on both pond outlets and the design of the ponds must be approved by the water resources coordinator. 8. The jurisdictional status of the low area in the northeastern corner of the site should be determined when field conditions permit. If the area Is determined to contain a wetland, no draining or filling of the wetland is allowed. 1 +.r.•., t...l.w•.•I ry~.w-.roues=i / 1 •i 1 d. • r(. 71 1 fi _I I l i ~.I l I t'~. f `i f I, i I ~IT Tl.r l~ !._~I -J!I I 1 ~ ~ 1 I 1 o0 ~I I cn E tt n r O C ' © O DOWCJ/ NAT ?y it Pon rti cc) o ~LF n 1 rn / i - yr yyy 2 D '~i esss .

BACKGROUND Maplewood Acres (Dart Transit) Is requesting approval of a Preliminary Subdivision consisting of twelve lots on approximately 112 acres located east of Lexington Avenue and north of Yankee Doodle Road In the SW ~/4 of Section 11. The proposed subdivision will complete the subdivision of 200 acres previously owned by Northwestern Mutual Life (NML) that had received preliminary subdivision approval In May 1995. Subsequent to receiving preliminary subdivision approval for the 200 acre site, NML sold the property to Dart Transit (dba Maplewood Acres). Due to delays In bringing the Final Subdivision application forward, Dart requested an extension of the preliminary subdivision approval. In reviewing the extension request, concerns were raised regarding the appropriateness of Industrial development along Yankee Doodle and Lexington particularly in light of the Promenade development and the area generally becoming more of a commercial corridor. In response to these concerns the City Council approved a one year preliminary subdivision extension for the northerly 120 acres of the 200 acre site In June 1996. The preliminary subdivision approval for the southerly 80 acres expired at this time. The northerly 120 acres ultimately received final subdivision approval In October 1996. There is no specific development proposal associated with this subdivision request; however, future development within this subdivision will be compatible with existing and future Industrial development to the north and east of the subject site. The suitability of Industrial development along the south and west perimeter of the site is less certain due to the residential character of existing development across Lexington and Yankee Doodle PARKS/TRAILS DEDICATION This development would be responsible for a cash parks dedication and a cash trails dedication. TREE PRESERVATION This development originally came before the APRNRC In April 1995 as Initial site development occurred. During this initial development process (Phase 1) 147 significant trees (12.7% of the total existing) were removed. No mitigation was required for this removal. Additional tree preservation has been agreed upon by the applicant for the removal of 42 oak trees on a knoll adjacent to Neil Armstrong Boulevard (see attached memo dated August 22, 1996). These trees were originally intended to be preserved during initial site development, but as grading proceeded It became necessary to remove the trees in order to "make the lot buildable". The attached memo states that an equal number of oak trees (42) will be protected or replaced in the southerly eighty acres of the site, in addition to the number that are required to be preserved via the Tree Preservation Ordinance. For this report, tree preservation issues will be presented on a "total site" basis(for details see attached memos prepared by Maplewood Acres, Inc. titled "Phase I and Phase II Eagandale Corporate Center: Tree Calculations") and are summarized as follows: 1,142 significant trees existing on site, before development 147 significant trees removed during Phase I site development 433 significant trees to be removed during Phase II site development 580 total significant trees estimated to be removed during Phase I & II this removal represents a removal percentage of 50.3% of the total existing significant trees. According to the City of Eagan Tree Preservation Ordinance, allowable removal for this type of development is set at 47.5% (548 trees). Therefore, the development of this site will likely exceed allowable removal limits by 2.8% or 32 trees. Mitigation for removal of significant trees in excess of allowable limits calculates to approximately 64 Category B trees. The mitigation is "approximately" calculated because specific trees, which will eventually be removed, are not yet determined, and the exact size of removed trees will determine the specific mitigation amounts. The applicant is proposing to fulfill required tree mitigation obligations by landscaping the Yankee Doodle boundary and pond perimeters with a variety of plant material in a three-phase operation. This perimeter landscaping will present a "natural look" with low shrubs on the exterior, backed by medium height shrubs and trees, and finally taller trees In the background. The applicant is proposing to install this type of landscaping in an area about 2,400' In length. It can be estimated that approximately 150 trees and hundreds of shrubs will be installed into this type of landscaping. Staff will coordinate with the applicant as development proceeds to ensure that all tree preservation obligations are met. WATER QUALITY/WETLANDS This site Is the southern half of the Eagandale Corporate Center subdivision which was reviewed by the Commission in Its entirety In April, 1995. The southeastern portion of the site will generate runoff that will discharge directly to Pond EP-2, an indirect contact recreation water body In the proposed North Park. The south western region of the site lies within the LeMay Lake watershed. There are no changes in the storm water management configuration for that portion of the site within the LeMay Lake watershed. However, the developer has requested that two pre- treatment basins In the southeastern portion of the site be dropped or reduced in size. Because this part of the development discharges directly to Pond EP-2, It Is important to fully treat the runoff to prevent further degradation of this water body. The ponding configuration originally approved met this standard. A re-evaluation of the need for the two upland detention areas indicates the same standard could be achieved by reducing the area and volume of the detention basins and excavating portions of the small (less than 1 acre) wetlands Into which they discharge. Staff does not recommend elimination of the detention basins because of the desire to provide some level of water quality protection to the wetlands themselves and the fact that a detention basin/wetland system in series is more effective than a single basin for treating storm water. Staff recommendations for re-sizing of the detention basin/wetland systems are as follows: 1. Pond EP-2.6 (constructed detention basin) and Pond EP-2.5 (existing .5 acre Type 2/3 wetland) must provide a minimum of 2 AF of additional wet volume to achieve acceptable treatment standards. The minimum mean depth of Pond EP-2.6 must be 3 feet. The increase in wet volume in the existing wetland must be accomplished by excavation In the northern two-thirds of the wetland. 2. Pond EP-2.7 (constructed detention basin) and Pond EP-2.4 (existing 1 acre Type 3 wetland) must provide a minimum of 3 acre-feet of additional wet volume to achieve acceptable treatment standards. The minimum mean depth of Pond EP-2.7 must be 3 feet. The increase in wet volume In the existing wetland must be accomplished by excavation in the southeastern two-thirds of the wetland. The most recent grading plans meet these criteria, though most of the expanded wet volume is accomplished through excavation of the wetlands. Other conditions recommended by staff involve notifying and securing approval from the Corps of Engineers regarding the proposed wetland excavation, adhering to the agreed upon 30-foot wide no-grading limit outside the delineated edge of the wetlands associated with Ponds DP- 11, EP-2.4, and EP-2.5, and construction of the Ponds DP-11.3 and DP- 11.2 to meet wetland replacement requirements as per the approved wetland replacement plan for this site. RECOMMENDATIONS 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication. 3. The Tree Preservation Plan shall be approved as proposed with the following conditions: • Tree preservation mitigation shall be met through the implementation of perimeter plantings (staff will work with the applicant to determine final tree mitigation amounts) along Yankee Doodle Road and around pond areas in accordance with the proposed phasing as described below: • Phase 1: Tree spading transplanting of material from within proposed grading areas of the site to areas outside of future grade limits (April/May 1997) • Phase 11: Additional tree spade transplanting of material from within the site plus purchased landscape material Installation (October 1997) • Phase III: The installation of purchased trees and shrubs (April/May 1998) 4. Tree Protective measures (i.e. 4 foot polyethylene laminate safety netting) shall 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. 5. The applicant shall 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. 6. Pond EP-2.6 (constructed detention basin) and Pond EP-2.5 (existing wetland) must provide a minimum of 2 AF of additional wet volume in total to achieve acceptable treatment of storm water. The minimum mean depth of Pond EP-2.6 must be 3 feet. The increase in wet volume in the existing wetland must be accomplished by excavation in the northern two-thirds of the wetland. 7. Pond EP-2.7 (constructed detention basin) and Pond EP-2.4 (existing wetland) must provide a minimum of 3 AF of additional wet volume In total to achieve acceptable treatment of storm water. The minimum mean depth of Pond EP-2.7 must be 3 feet. The Increase in wet volume in the existing wetland must be accomplished by excavation In the southeastern two-thirds of the wetland. 35. 8. Skimmers should be placed on the outlets of Ponds EP-2.6 and EP-2.7. 9. The developer is required to notify and secure approval from the Corps of Engineers regarding the Nationwide 26 wetland permit, since the original application for the site did not include proposals for wetland excavation. 10. No grading should be allowed within 30 feet of the delineated edge of the wetland associated with Pond DP- 11, except for 450 lineal feet along the south end of the basin to allow for road and detention basin/replacement wetland construction. A 30-foot wide undisturbed buffer shall also be preserved around the wetlands associated with Ponds EP- 2.4 and EP-2.5. Buffers shall be marked on all grading plans. 11. Construction of Ponds DP-1 1.3 and DP-1 1.2 should be constructed to satisfy requirements for wetland mitigation as per the approved wetland replacement plan for this site. 1 y4 fi ti • I lo•il Mil r. r • _ j I f r til I T t * fI•- 1 v 1. 41- • o -Tj 0 C) VOW m. n m •-I 11 8.1 all MICH 2.1 1.

Lilly, Landscape Architect/Parks Planner DATE: April 9, 1997 RE: Community Park Signs BACKGROUND The Commission reviewed this issue at their March 17 meeting and asked staff to research other materials for sign construction beyond redwood. The specific request was to determine If another material could be more cost effective, durable and aesthetically pleasing in appearance. The results of that research are as follows: REDWOOD POSITIVES CONCERNS FABRICATORS COMMENTS Highly decay resistant wood High demand/limited supply This has the overall best appearance when Lack of knots Concern for endangering species completed. Redwood is easy to work with and provides a high quality appearance and Easy to work with Highest cost durability. Holds paint and stain well Very little pitch Ideal for sandblasting WESTERN RED CEDAR POSITIVES CONCERNS FABRICATORS COMMENTS Highly decay resistant wood Rougher appearance than redwood Durability nearly as good as redwood, but Possibility of knots Softer than redwood appearance is rougher than redwood. Although cost of wood is approximately 25% Easy to work with Does not hold nails well less than redwood, additional work to support Holds paint and stain well Not as rigid as redwood (needs to red cedar Increases the cost of the sign. Very little pitch be supported) Marginally acceptable for sandblasting SOUTHERN YELLOW PINE POSITIVES CONCERNS FABRICATORS COMMENTS Very strong wood (stronger Not naturall decay resistant Fabricators will not consider this product for than redwood and cedar) Profusion of knots sandblasting Holds nails well Prone to warping Lowest cost (approximately High pitch content 50% less than red cedar) Does not hold paint well Does not sandblast very well •rr 60 Staff has attached a matrix which Identifies other woods showing their general suitability and performance. Also attached is a copy of the March memo for your reference. COMMENTS: The Commission has expressed concern for using redwood for the proposed community signs. If this remains a concern, then consideration of an alternate product for sign construction should be considered. Since a sandblasted finish does not lend itself to other wood types as well as redwood, the Commission may wish to reconsider the style and type of sign should they choose not to use redwood. FOR COMMISSION ACTION: After reviewing the above, the Commission should make one of the following recommendations: 1. Proceed with fabrication of double sided community park signs at Thomas Lake Park and Trapp Farm Park constructed out of. a. Redwood b. Western Red Cedar 2. Do not construct community park signs. 3. Reconsider design parameters for the sign and provide direction as to the elements for a new sign. 4.

PITCH city of eagan MEMO TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: C.). LILLY, LANDSCAPE ARCHITECT/PARK PLANNER DATE: MARCH If,, 1997 RE: COMMUNITY PARK SIGNAGE BACKGROUND As recently as four years ago all park identification signs were the same. Although this has worked very well for neighborhood parks, It has let to a degree of confusion with the public in being able to Identify larger community parks. This has resulted in staff having to explain how to find these parks and visitors trying to find them. To help resolve some of these Issues, staff developed new criteria for community park Identification signs. The size of the sign was Increased with a unique design different than neighborhood park signs to assist the public in Identifying community parks. Two examples of the new design are at Blackhawk Park and Lexington Diffley Athletic Fields. The monumental nature of these signs creates an Identifiable landmark that Eagan residents and visitors can easily locate. Staff would like to add two more community park signs at Thomas Lake Park and Trapp Farm Park In 1997. ANALYSIS Last January sketches were drawn for future community park signs with Concept A and B presented to the Commission for their feedback. The Commission requested that cost estimates be obtained for the signs. Sign fabricators were contacted and given artistic license to develop the best sign they could for the most reasonable price. An important criteria for the fabricators was that the sign was to be built with durable, aesthetically pleasing materials. Four sign fabricators submitted designs and associated cost estimates. The estimate from Cylex, inc. was eliminated since the weight of the imitation stone would require a footed concrete wall to support It. The cost for Concept A was $ 13,675 and Concept B was $9,345 excluding shipping from Tempe, Arizona. The manufacturing process for this type of sign would also not allow for a see-through tree symbol. The remaining three sign manufacturers slightly altered concept plans A and B to enhance the aesthetics and to get the best cost estimate. Although designs varied, the materials they selected were fairly consistant. All sign materials selected are sandblasted redwood, all Internal frames are a combination of steel and wood and all tree symbols are metal and see through. Some concerns had been voiced by Commission Members regarding the use of redwood. When asked about options, sign fabricators stated that redwood Is most often used because of Its tendency not to crack or have knots In the wood. Redwood by Itself Is not an especially strong wood however with steel and wood Internal framework anchored to a concrete footing, It should be as strong as It needs to be. LOCATION The sign for Thomas Lake Park on Pilot Knob Road must be double sided for best visibility. The sign will be aligned perpendicular to the curb for optimal reading from the north and south bound lanes. The sign for Trapp Farm Park on Wilderness Run Road may be either single or double sided since the sign would be located at the apex of a curve In the road. This option for a single sided sign is presented as a cost saving measure. LANDSCAPING All signs will be mounted on supports three feet above the surrounding ground elevation. This will keep them above normal snow depths and allow sufficient room for landscaping around their bases. Landscape materials suggested around the base of these signs are perennial flowers such as purple and white coneflower, black eyed susan, rose coreopsis and daylilys. These varieties are long blooming and tend to be more drought tolerant than most species. A gently curving perennial border will also make lawn care around these signs easier to maintain. The combination of beautiful signage and landscaping will further enhance the positive character and Image of the community parks. SIGNAGE COST The following Is a cost analysis for both singe and double sided signs. Staff requests the Commission select one signage concept for Thomas Lake and one for Trapp Farm Park. The Commission may select one fabricator for both signs or different companies for each location. A. SIGN CITY. Annandale.

MN Concept A Single Sided $4,100 Double Sided 4,900 Concept B Single Sided 4,600 Double Sided 5,400 IMPLEMENTATION From the time the order Is received by a sign shop It takes approximately 10 weeks to construct the signs. If the order Is placed mid-March, the signs should be ready to Install by the first week of June. During the month of May, the exact sign locations could be staked and parks maintenance staff can pour the concrete footings so they will have two weeks to set prior to Installation of the signs. Once the signs are Installed and approved, landscaping could be completed during the month of June. The same process could be followed until all of the community park signs have been updated.

This was addressed at several of our Board Steve Luck meetings with some discussion; I left it up to the Facilities individual directors to advise me of what they felt was the Danldekner most pressing needs for thier programs for the coming House Basketball season. I received just a few specific requests. .-d & aBothwell Travel Baseball has requested wire drags that are hand drawn ?raveling Basketbal for the following baseball fields. They would would provide Terry Thorvilson the people to use them. One each for Goat Hill and Rahn In-House Baseball Park, and two to the fields behind Northview. Mike Bailey Traveling Baseball In-house softball has provided a review of the field conditions at the ball fields that they used last season. A Steve In-House chaeppi copy is enclosed. Steve Schaeppi has also given a copy to In-House Dorothy Peterson and has discussed this with her to some Tom Schmidt extent. He has has also expressed a need for equipment Traveling Softball boxes at many of the fields. This could allow for less Mark Lieberman equipment such as bases and pinching rubbers. Now, every Track team is issued a set of bases as well as a pitching rubber. It would also lead to less wear and tear on the equipment Don Carroll bags as well on the coaches who have to lug this to each In-House Soccer field along with all the other equipment. We have installed John Bunker boxes at a number of fields in the past few years and this Soccer seems to have worked very well. Boxes for softball fields would probably not have to be quite as large as those Frank Caldwell installed previously at baseball fields. Fra Football We appreciate your efforts in maintaining the fields to a very high level. I feel that this one reason why there were not other specific requests at this time. I will be working to put together a list of some of our longer term goals and needs and would hope get this to you in the near future. If you should have any questions, please do not hesitate to call.

This year's meeting is scheduled for 4:30 PM, Wednesday, May 7, at Camp Sacajawea in Lebanon Hills Regional Park. (Directional map enclosed.) The meeting is intended to facilitate communication on our complementary roles as public agencies providing recreation services to the residents of Dakota County. This year we would like to focus on recreation and education programs. There will be time on the agenda for a short, 5 minutes or so, overview from each Committee, of the types of programs conducted or planned to be offered to the public. If you are unable to make a presentation, I would appreciate it if you could make arrangements with another Committee member or City staff to do so. Information will also be presented on current funding opportunities. Lastly, the agenda will allow time for informal discussion of our roles as park agencies and for whatever other subject matter the group finds important to our mutual interests. Supper will be provided, so please RSVP, Lana Rotty, at the Dakota County Park Department Office, 438-4660, by Monday, May 5, 1997, so meal arrangements can be made.
