This development is not subject to any further water quality requirements. 4. This development shall be responsible for a cash parks dedication. 5. This development shall be responsible for a cash trails dedication. t3lrahndifAth a: v&: DEERWOOD TOWNHOMES - GOOD VALUE HOMES Advisory Parks, Recreation and Natural Resources Commission January 12, 1995 FOR COMMISSION REVIEW AND ACTION: 1. The Tree Preservation Plan is acceptable as presented. 2. This development would be subject to a cash parks dedication. 3. This development would be subject to a cash trails dedication. 4. There are no jurisdictional wetlands on this site. 5. This development would be subject to a cash water quality requirement for any shortfall in treatment provided by pond BP-33.

The developer shall provide a 30 foot vegetative, ungraded buffer strip from the normal water level along the north edge of Pond BP-32 2. The developer shall pay a cash water quality dedication for any shortfall in storm water treatment by Pond BP-31/ 3. The Tree Preservation Plan is unacceptable. The developer shall revise the Plan to incorporate the impact of the utility/street extension and also provide information on the significant woodlands on site that have been verified in the field by staff. 4. This development would be responsible for a cash parks dedication. 5. This development would be responsible for a cash trails dedication. c3/h*rwdxw T BLACKHAWK FOREST - MAPLEWOOD DEVELOPMENT, INC. Advisory Parks, Recreation and Natural Resources Commission January 12, 1995 " FOR COMMISSION REVIEW AND ACTION: 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication. 3. The developer shall install fencing at the critical root zone (a distance of one foot away from the tree trunk for every inch in diameter as measured 54' above grade) around all trees depicted on the Tree Preservation Plan to be saved. 4. The developer shall contact the City so an inspection can be performed of the preventive measures installed prior to any site grading, trenching, filling, compaction, or change in soil chemistry taking place. 5. The developer shall provide 176 category A and B trees for tree preservation mitigation. 6. The developer shall provide a 30 foot natural ungraded buffer strip along the edge of each wetland. 7. The wetland mitigation area adjacent to Wetland Basin 3 should be dropped because it does not appear to meet Wetland Conservation Act criteria for the use of stormwater detention basins as wetland replacement. If needed, this mitigation area should be located adjacent to other basins in the plat that do not receive direct stormwater discharge. 8. Because they will be expanded to satisfy wetland replacement requirements, wetland basins 2, 5, and 6 should not receive any direct discharge from the storm sewer system. 9. The wetland replacement plan submitted with the plat application is incomplete. A correct and complete replacement plan must be received by staff no later than Wednesday, January 25, 1995 in orderto allow sufficient time for public review of the application priorto a City Council decision regarding approval of the plat on February 21, 1995. 10. There are several areas adjacent to wetland basins 2, 3, 5 and 10 where grading contours are shown up to the wetland boundary. These are areas where unintended wetland filling could occur in violation of the WCA. The developer should address specifically how unintended filling of wetland areas due to erosion will be prevented in these locations. 11. The developer shall avoid discharging raw stormwater into Pond AP-27. 12. The developer shall route the discharge from Pond AP-27 directly to the storm trunk in Robin Lane instead of to the proposed stormwater basin in wetland basin 3. 13. After development of the site is completed, developer shall eliminate the pre-treatment basin adjacent to the wetland basin 3 stormwater treatment pond. 14. The developer shall increase the wet pond volume of the stormwater treatment basin associated with wetland basin 3 by excavation as per water resources staff direction. 15. Developer shall route raw runoff from Deer Pond Circle and the eastern segment of Brown Bear Trail either to the proposed stormwater basin north of wetland basin 5 or directly to the trunk stormsewer F in Robin Lane, if feasible. 16. The proposed pre-treatment basin for stormwater runoff discharged to Pond AP-38 from the western segment of Brown Bear Trail should be eliminated, since it is very small and poorly located. cMidm"Ist MEMO city of eagan DATE: JANUARY 10, 1995 TO: ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION FROM: KEN VRAA, DIRECTOR OF PARKS AND RECREATION SUBJECT: JANUARY 12, 1995 COMMISSION MEETING Prior to the regularly scheduled Commission meeting, both the Natural Resources Sub- Committee and the Recreation Sub-Committee will meet.

BACKGROUND STORY The Rahncliff 2nd Addition Planned Development was created in 1988 and provided a mixture of commercial uses consisting of 9 lots on 16.8 acres. Specifically, the PD provided for a 9,000 s.£ bank, 64,000 s.fi of retail, two restaurants (8,400 s.f. total), 12,000 s.f. office and/or medical clinic building, and 50,000 st multi-level office building with 60 underground parking spaces. Six of the nine lots in the PD have developed and the three remaining lots are approved for the following uses: Lot 1, Block 1, Rahncliff 3rd Addition - 20,000 s.f. retail Lot 2, Block 1, Rahncliff 2nd Addition - 14,000 s.f. retail Lot 1, Block 2, Rahncliff 2nd Addition - 50,000 s.f. multi-level office with 60 underground parking spaces. In 1993, the City Council approved a PD amendment changing the use for Lot 2, Block 2, Rahncliff 3rd from a 12,000 s.f. office/medical clinic to hotel to allow the construction of the 70 unit Holiday Inn Express. EXISTING CONDITIONS The preliminary subdivision encompasses two previously platted lots; Lot 2, Block 2, Rahncliff 3rd Addition (contains existing hotel) and Lot 2, Block 1, Rahncliff 2nd Addition which is undeveloped but has been previously graded and therefore contains little grade change and no significant trees. The southern area of the undeveloped parcel contains side slopes and a portion of Pond AP-44, the majority of which is located within Kettle park. SURROUNDING USES The following uses, zoning and comprehensive plan designations surround the subject property: North - Undeveloped; zoned PD; guided Commercial Planned Development South - Kettle park; zoned and designated Parks East - Interstate 35E West - Undeveloped; zoned Planned Development/Limited Business; guided LB I• Planning Report - Rahncliff 4th Addition January 24, 1995 Page 4 EVALUATION OF REQUEST A. Preliminary Subdivision L= - The proposed subdivision will consist of three lots: Lot 1 - Existing hotel plus expansion (3S acres), Lot 2 - Class I restaurant (1.6 acres), and Lot 3 - Medical clinic (0.5 acres). Park Dedication - Park dedication requirements have previously been met. Water Quality - Pond AP-44 is located just south of the site (in Kettle park) and was created in 1989 and designed to handle site runoff and to fulfill water quality and flood peak flow control for the Rahncliff additions. Therefore, this application is not subject to any further water quality requirements. B. Planned Development Amendment If approved, the hotel expansion will constitute the Final Planned Development for the proposed Lot 1, Block 1, Rahncliff 4th Addition, which requires the developer to submit the following plans: " Final Site Plan ' Final Building Elevation Plan • Final Sign Plan Final Landscape Plan The restaurant and medical clinic on proposed Lots 2 and 3, Block 1, Rahncliff 4th Addition, respectively, constitute an amendment to the Preliminary Planned Development. These two components of the PD will achieve Final Planned Development status when exact users have been identified and corresponding Site plans have been reviewed by the Advisory Planning Commission and approved by the City Council. Q ati'bili , with Surrounding Area - The hotel, restaurant, and medical clinic are compatible with the surrounding land uses. The proposed hotel expansion and the addition of a Class I (traditional sit-down) restaurant are compatible with this site in particular, and the area in general; however, introducing a third user causes the entire site to become congested with regard to parking, parking/drive aisle setbacks, and internal circulation. Setbacks - All building setbacks are met. Revisions to the Site Plan are necessary to meet required parking and drive aisle setbacks. Planning Report - Rahncliff 4th Addition January 24, 1995 Page 5 Site Plan - With revisions, the Site Plan is acceptable. The applicant has revised the Site Plan once; however, further modifications to the design of the parking areas are necessary to ensure safe internal traffic circulation. These revisions will likely result in the loss of a number of parking spaces. Additionally, the on-site parking requirements, by use, are not met. Trash /ReoTling Enclosure - All trash/recycling containers should be stored within the principal building or in an enclosure attached to the building that is constructed of the same building materials as the principal building. Landscape Plan - The proposed Landscape Plan is not acceptable. The Plan should be revised to include an overall landscaping plan for the entire subdivision including a landscaped buffer along the south boundary of Lot 2 and a landscaped berm along all public roadways to screen parking areas. Also, all landscaped and green areas shall be served by an underground irrigation system. Signage - As part of the Planned Development, the developer should provide an overall signage plan, including building elevation plans, depicting all proposed signage. Pedestrian Circulation - The developer should provide a pedestrian circulation plan that provides for safe pedestrian movement between the proposed uses. Ughting Plan - The developer should submit a lighting plan that depicts the proposed lighting scheme, identifies the type of light poles/fixtures to be used throughout the 4th addition, and depicts the type of bollard lighting proposed for pedestrian walkways within the development. Grading etlands - The Grading Plan submitted is acceptable. The only wetland on site is the fringe wetland associated with Pond AP-44. Subsequent to the creation of this ponding area, it was classified for wildlife habitat purposes. The developer is not proposing any filling or draining of the wetland; however, due to the classification, the developer should maintain an ungraded, natural buffer at least 20' back from the Normal Water Level (NWL). Storm Drainage - The Storm Sewer Plan submitted is acceptable. Tbere is existing storm sewer to serve the development that discharges into Pond AP-44. The developer is proposing to relocate a portion of this 30" line to accommodate the location of the addition to the motel. The surface drainage from this site is proposed to be directed to existing and new catch basins which discharge into the existing storm sewer. Utilities - The Utility Plan submitted is acceptable. Sanitary sewer and water main are available to serve the proposed development. The developer should provide an q. Planning Report - Rahncliff 4th Addition January 24, 1995 Page 6 inspection/monitoring manhole at the edge of the easement for each sanitary sewer line. Access eet Design - Access to the site is proposed at three points (two of which currently serve the existing hotel) from Rahncliff Court and one from Rahncliff Road. These new driveway openings should be constructed with concrete aprons. The applicant is proposing internal circulation between all three proposed uses. The developer should prepare a shared access easement document for review and approval by the City Attorney and record this document with the plat at Dakota County. Easements Mi - -Way - The developer is proposing to vacate the existing blanket easement over this property and then dedicate, with the final subdivision, the necessary ponding and utility easements associated with the proposed Rahncliff 4th Addition. The developer should submit the petition to vacate the existing easements prior to final plat approval. Tree Preservation Policv - There are no significant trees located on the site. Park Dedication - Park dedication requirements have previously been met. SUMMARY/CONCLUSION The proposed uses are compatible with the area although meeting the on site parking requirements for the hotel and restaurant may eliminate the proposed medical office use in the northwest corner of the site. A number of revisions to the site and other plans need to occur before this item proceeds to the final subdivision and final planned development phase. ACTION TO BE CONSIDERED Planned Development Amendment To recommend approval/denial of a Planned Development Amendment to allow a to allow a 50 unit expansion of the Holiday Inn Express, a 6,500 st restaurant, and a 2,500 s.f. medical office building on the 3.8 acre Lot 1, Block 2, Rahncliff 2nd Addition. Preliminary Subdivision To recommend approval/denial of the Rahncliff 4th Addition Preliminary Subdivision consisting of three lots on 5.6 acres, subject to the conditions listed below. 1 Planning Report - Rahncliff 4th Addition January 24, 1995 Page 7 Subdivision Standard Conditions 1.

That the design of the subdivision or the improvements will not conflict with easements of record or with easements established by judgement of court. H. That completion of the proposed development of the subdivision can be completed in a timely manner so as not to cause an economic burden upon the City for maintenance, repayment of bonds or similar burden. L That the subdivision has been properly planned for possible solar energy system use within the subdivision or as it relates to adjacent property. (Refer to City Handbook on Solar Access). J. That the design of public improvements for the subdivision is compatible and consistent with the platting or approved preliminary plat on adjacent lands. K. That the subdivision is in compliance with those standards set forth in that certain document entitled "City of Eagan Water Quality Management Plan for the Gun Club Lake Watershed Management Organization" which document is properly approved and filed with the office of the City Clerk hereinafter referred to as the "Water Quality Management Plan". Said document and all of the notations, references and other information contained therein shall have the same force and effect as if fully set down herein and is hereby made a part of this Chapter by reference and incorporated herein as fully as if set forth herein at length. It shall be the responsibility of the City Clerk to maintain the Water Quality Management Plan and make the same available to the public. BACKGROUND ISTORY The site was originally split by Deerwood Drive prior to the Deerwood Drive realignment associated with the construction of I-35E. The southern portion of the site (3.4 acres) which is currently zoned Ag, was formally separated from the 35.2 acre Francis Franz parcel via a Waiver of Subdivision in 1994. The remaining 434 acres of the site is currently zoned PD within the Blackhawk Park Planned Development; however, I-35E separates this property from the northern portion of the PD. EXISTING CONDITIONS The site is relatively flat with grade changes of approximately 10 feet. There is some Planning Report - Deerwood Townhomes January 24, 1995 Page 3 concentrated areas of mature vegetation and there are no structures on site. Along the northerly edge of the site, the freeway is approximately 20-25 feet lower than the proposed townhouses along the north property line. SURROUNDING USES The following uses, zoning and comprehensive plan designations surround the subject property: North - Interstate 35E South - Underdeveloped; zoned Ag; and designated D-II East - Underdeveloped; zoned Ag; and designated D-II West - Interstate 35E EVALUATION OF REQUEST A. Rezoning The proposed R-3 zoning allows for twnhomes with a maximum density of 7.3 units/acre. The existing D-II Guide Plan designation provides for "Mixed Residential", 0-6 units/acre. Rezoning the area to R-3 is consistent with the Guide Plan designation of D-II provided the density of the townhouse development does not exceed 6 units/acre., As mentioned previously, the subdivision proposed for this site consists of 37 lots for 36 townhouse units which results in a density of 4.7 units/acre. As proposed, the rezoning and subdivision are consistent with the Guide Plan residential density designation. B. Preliminary Subdivision Co=ati'bilily with Surrounding Area - The applicant is proposing a unit type and density that should be compatible with the anticipated future development in the area given the Ag zoning and D-II Guide Plan designation of the property surrounding this site. Homeowners Association - The developer should be responsible for preparing and recording, with the subdivision, appropriate documents establishing a Homeowners' Association. The documents should be submitted and approved by the City Attorney's office prior to final subdivision approval. Transfers of common areas to the Homeowners' Association should be recorded with the subdivision. 1 ensi - The 4.7 unit/acre density is consistent with the existing Guide Plan designation of 0-6 units/acre and with the proposed R-3 zoning. a~ Planning Report - Deerwood Townhomes January 24, 1995 Page 4 I= - The proposed subdivision creates 36 townhouse lots and one lot that encompasses all of the common area. Setbacks - All R-3, public street, private street, and freeway right-of-way setback requirements are met. Architecture - The developer is proposing similar buildings to those in the Pond View Townhome project approved in 1994. The development will provide a mixture of 2 and 3 bedroom units and all buildings will include maintenance free exteriors with brick accents. Parking - The Site Plan provides Code required on site parking; however, the layout does not provide for any guest or overflow parking spaces. While not required by City Code, the Site Plan should be revised to include 9 (one space for each four units) additional parking spaces for guest and/or overflow parking. Landscani^ - With minor revisions, the landscape Plan is acceptable. The City Code requires landscaping above and beyond what is normally required when the property abuts freeway right-of-way. The Plan should be revised to provide additional plantings and berming along the.I-35E right-of-way. Additionally, all landscaped and green areas should be served by an underground irrigation system. Tree Preservation Policy - The Tree Preservation Plan is acceptable. There are 32 significant trees located on the site, primarily concentrated along the eastern property line and northwest corner of the site.. The Plan calls for 3 significant trees to be removed, which is slightly under 1% removal. Park Dedication - The site is located in Park Service District 21, with the nearest park actually being Blackhawk park. Deerwood school across the street, provides open space for recreation purposes. The City is considering development of a park south of Deerwood Drive, perhaps adjacent to Blackhawk Middle school. The developer should be responsible for a cash park and trail dedication. Grading etlands - The Grading Plan submitted is acceptable. The majority of the site will be disturbed by grading to prepare for the internal streets and townhome pads. Up to 6 feet of fill and cuts of up to 8 feet will be required to prepare the site. There is one apparent wetland on site, but evidence was provided by the developer, and approved by staff, that supports an exemption from regulations under the Wetland Conversation Act (WCA). Storm DrainageMter Ouality - The Storm Drainage Plan is acceptable. Storm sewer exists to serve the site and should be extended to the pond located west of the site (Pond A Planning Report - Deerwood Townhomes January 24, 1995 Page 5 BP-33), which will require a permit from MnDot to work in their right-of-way. A cash dedication should be required for any shortfall in treatment provided by pond BP 33. The proposed private street system will drain to this pond, which was constructed by MnDOT as part of the I-35E project and is located in MnDOT right-of-way. Pond BP-33 drains in a northerly direction and eventually discharges to Blackhawk Lake. Utilities - The Utility Plan submitted is acceptable. The applicant has petitioned the City for a public improvement that will extend sanitary sewer and water main to this site from the east. An 8" sanitary sewer line needs to be extended for 1,000 feet to the east to serve this site. Also, an 18" watermain needs to be extended from 300 feet to the east to provide water service to this site. An exhibit is attached to illustrate these utility extensions. Access /Street Design - Access to the site is proposed via two points along Deerwood Drive. The applicant is proposing a private loop street for internal access and circulation. There will be no units taking direct access from Deerwood Drive. All private streets should be constructed with concrete curb & gutter. The westerly driveway connection to Deerwood Drive should connect to Deerwood Drive directly across from the Francis Franz driveway location. The developer should also be required to remove the two existing driveway openings that currently connect to Deerwood Drive. Easements /$ight-of-M ermits - The developer is proposing to vacate three areas of excess City right-of-way and should petition the City for these vacations so they can occur in conjunction with final subdivision approval. BUi MARY=NCLUSION The proposed development is consistent with the requested rezoning and the existing Comprehensive Land Use Guide Plan Designation. The land use and density appear to be compatible with the subject site and the anticipated development of the surrounding property. City services can be extended to serve the site and the applicant has petitioned the City to extend water main and sanitary sewer via a public improvement project.

Waters HEARING DATE: January 24, 1995 PROPERTY OWNER: Esther E. Bjelland PREPARED BY: Mike Ridley Orrin Thompson Homes REQUEST: Rezoning, Preliminary Subdivision (Ridgecliff Woods) LOCATION: NE 1/4 of Section 32 COMPREHENSIVE PLAN: D-I, Single Family (0-3 units/acre) ZONING: Agricultural, Single Family (Ag, R-1) SUMMARY OF REQUEST James M. Waters, LGA Investment Group, Inc. is requesting approval of a Rezoning of 3 acres from Ag to R-1 and a Preliminary Subdivision consisting of 8 lots on 4.3 acres located on the south side of Cliff Road just east of Lenore Lane. AUTHORITY FOR REVIEW City Code Chapter 13, Section 1320, Subd. 6. states: In the case of subdivision, the Planning Commission and the Council shall be guided by criteria, including the following, in approving, denying or establishing conditions related thereto: A. That the proposed subdivision does comply with applicable City Code provisions and the Comprehensive Guide Plan. B. That the design or improvement of the proposed subdivision complies with applicable plans of Dakota County, State of Minnesota, or the Metropolitan Council. C. That the physical characteristics of the site including, but not limited to, topography, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, water storage, and retention are such that the site is suitable for the type of development or use contemplated. D. That the site physically is suitable for the proposed density of development. E. That the design of the subdivision or the proposed improvements is not likely to cause environmental damage. Planning Report - Ridgecliff Woods January 24, 1995 Page 2 F. That the design of the subdivision or the type of improvements is not likely to cause health problems. G. That the design of the subdivision or the improvements will not conflict with easements of record or with easements established by judgement of court. H. That completion of the proposed development of the subdivision can be completed in a timely manner so as not to cause an economic burden upon the City for maintenance, repayment of bonds or similar burden. L That the subdivision has been properly planned for possible solar energy system use within the subdivision or as it relates to adjacent property. (Refer to City Handbook on Solar Access). J. That the design of public improvements for the subdivision is compatible and consistent with the platting or approved preliminary plat on adjacent lands. K. That the subdivision is in compliance with those standards set forth in that certain document entitled "City of Eagan Water Quality Management Plan for the Gun Club Lake Watershed Management Organization" which document is properly approved and filed with the office of the City Clerk hereinafter referred to as the "Water Quality Management Plan". Said document and all of the notations, references and other information contained therein shall have the same force and effect as if fully set down herein and is hereby made a part of this Chapter by reference and incorporated herein as fully as if set forth herein at length. It shall be the responsibility of the City Clerk to maintain the Water Quality Management Plan and make the same available to the public. BACKGROUND ISTORY The 13 acre parcel currently owned by Orrin Thompson Homes, Inc. was rezoned to R-1 and platted as Outlot B, Ridgecliff 1st Addition in 1980. The Development Contract for Ridgecliff First Addition states: "The developer and owner shall be required to grant the City a 60-foot wide street easement over the property which lies between the Bjelland and Stertz properties for a future street extension. The proposed lot at this location shall be shown as an outlot on the final plat." The Bjelland parcel to the west of Outlot B, Ridgecliff First Addition is included with this application and the Stertz property to the east of the outlot is not involved with this request. EXISTING CONDITIONS Planning Report - Ridgecliff Woods January 24, 1995 Page 3 There are no structures on either of the two parcels under consideration; however, there are two driveway curb cuts that connect to Cliff Road. Nokia Way emends east approximately 150' from Lenore Lane and dead-ends at the western edge of the Bjelland property. The site grade falls approximately 30' from the high point near the northeast corner to the low points located on the west edge and southwest corner. The majority of the site is heavily wooded and portions of two wetlands are located on site. SURROUNDING USES The following uses, zoning and comprehensive plan designations surround the subject property. North - Woodgate 2nd Addition; zoned PD; designated D-II, Mixed Residential (0-6u/a). South - Ridgecliff 1st Addition; zoned R-1; designated D-I, Single Family. East - Ridgecliff 1st Addition West - Ridgecliff 1st Addition EYALUA31ON OF REQUEST A. Rezoning The rezoning request is consistent with the D-I Guide Plan designation and compatible with the existing single family development surrounding this site. B. Preliminary Plat Co=atibili , with Surrounding Area - The proposed single family development is compatible with the surrounding single family land use and should be compatible with the anticipated future single family development to the east of this site. However, the developer is proposing a cul-de-sac to serve the site which is not consistent with the City's intended street design that would connect the two Nokia Way dead-ends thereby establishing Nokia Way as a through street to serve this area and eliminate direct access to County Road 32 (Cliff Road). Density - As proposed, the subdivision density is 1.9 units/acre which is consistent the proposed R-1 zoning and the existing D-I Guide Plan designation. L= - The applicant is proposing 8 lots that range in size from 14,876 - 28,533 s.£ with an average lot size of 19,070 s.f. 0. Planning Report - Ridgecliff Woods January 24, 1995 Page 4 Setbacks - As proposed, all lots will have sufficient width and depth to accommodate all R-1 Zoning District setback requirements. GradingMtlands - With modifications, the Grading Plan is acceptable. The site contains a ridge down the middle where the proposed street would be located and the backyard areas contain slopes that will work well for walk-out lots. Also, the proposed grading shows that the northerly 100 feet of the site will not be disturbed which will provide a good buffer between Cliff Road and the proposed homes. The grading plan calls for approximately 4 feet of fill to be placed along the northerly edge of the pond to the south (Pond BP-32). To protect the vegetation and trees and to control erosion into the pond, the developer should provide a 30 foot natural, ungraded buffer strip back from the normal water level along the north edge of the pond. This will require modification to the grading plan on Lot 7 and 8. Storm Drainage LW-Wer Ouality - The Storm Drainage Plan is acceptable. The developer is proposing to construct a storm sewer system that will collect runoff from the streets and front yards and then drain it into the pond at the northwest corner of the site (Pond BP-31). Any shortfall in treatment of storm water by pond BP-31 should be made up through a cash water quality dedication. Utilities - With modifications, the Utility Plan is acceptable. Sanitary sewer and water main were stubbed to this site from the Ridgecliff ist Addition in 1980. The Utility Plan extends these utilities into the site only far enough to serve the proposed homes. The City requires developers to extend utilities to the edge of their property (unless development will be phased); therefore, the Utility Plan should be revised to include the extension of these utility lines to the east edge of the site. Access ' 15treet Design - Nokia Way has been planned to be a through street, looping between Lenore Lane and Karis Way, since Ridgecliff First Addition was subdivided in 1980. The intent of this connection was to eventually eliminate all direct private access to Cliff Road. The applicant is proposing an extension of the Nokia Way stub street from Lenore Lane to a cul-de-sac end within the subject property. This design will prevent any further easterly extension of Nokia Way and connection to the existing Nokia Way dead-end off of Karis Way. By precluding this connection, the Nokia Way extension from Karis Way will'remain a dead-end street, serving 63 homes, that is over 1,400 feet long, which is not consistent with the City Code allowed maximum cul-de-sac length of 500'. The developer has suggested that the Nokia Way dead-end from Karis Way could be extended to the west in the future to serve the two unplatted parcels east of the subject site Planning Report - Ridgecliff Woods January 24, 1995 Page 5 and then angle north and connect to Cliff Road but this would defeat the original purpose of malting Nokia Way a through street. The developer should revise the subdivision layout to incorporate the extension of Nokia Way to the east property line of the site with a temporary cul-de-sac bubble on the north side of the new street extension. Also, the developer should be required to remove the two existing driveway openings to Cliff Road and add curb and gutter. Easements/Kight-Of-WU - Dakota County is requesting that 75 feet of half right-of-way be dedicated on the plat to allow for the future upgrading of Cliff Road. The plat shall also dedicate restricted access along the north edge of this site that would not allow any driveway connections out to Cliff Road. The preliminary plat shows the right-of-way for the extension of Nokia Way at the width of 50 feet which is consistent with a cul-de-sac street; however, a 60 r-o-w is necessary for a through street. The preliminary plat should be revised to incorporate a 60' r-o-w through the subdivision. As shown on the preliminary plat, the developer should dedicate drainage and utility easements over Ponds BP-32 and BP-31. Tree Preservation - The Tree Preservation Plan submitted is unacceptable. The developer has revised the Plan to reduce the tree loss from 45.5 to 37.5 percent. This percentage of iemoval exceeds the 25% allowed removal for the first phase of development; however, the 37.5 % represents total tree loss because the developer is proposing to install utilities, construct the street, and clear the house pads all in one phase. The Tree Preservation Plan does not reflect the additional tree loss that will occur by the required utility and possible street extension to the east edge of the site. Initial review of these extensions show that additional trees will be lost although the reconfiguration of the lots will allow more flexibility with pad locations that will likely result in no net loss of trees for the site. The developer should revise the Plan to incorporate the impact of the utility/street extension and also provide information on the significant woodlands on site that have been verified in the field by staf Park Dedication - The proposed subdivision is located in Park Service Area 35. The nearest park is Ridgecliff park. The developer should be responsible for a cash park and trail dedication. Planning Report - Ridgecliff Woods January 24, 1995 Page 6 SUMMARYjCONCLUSION The proposed zoning and land use is consistent with the Comprehensive Guide Plan Designation and the development surrounding the site. The Developer should redesign the subdivision to incorporate the extension of Nokia Way to the east edge of the property, including the provision of a temporary cul-de-sac bubble on the north side of the new street. ACTION TO BE CONSIDERED Rezoning To recommend approval/denial of a rezoning of 3 acres from Ag to R-1, Single Family.

It shall be the responsibility of the City Clerk to maintain the Water Quality Management Plan and make the same available to the public. BACKGROUND I TORY The 38 acre site is undeveloped and except for the portion just north of Silver Bell Road (Outlot A. Townview First Addition, platted in 1971), the remainder of the site is unplatted. The subject site was reviewed as part of the 98 acre "Area K" in the City's Multi-Family Residential Land Use Study. Area K bad a mix of zonings (Ag, R-3, and R-4) and Guide Plan designations (D-III and D-M in place at the time of the review (1989-1990). In 1990, the City Council approved a rezoning to R-3 and a Guide Plan amendment to D-III for the entire 98 acre study area. C0~ Planning Report - Blackhawk Forest January 24, 1995 Page 3 EXISTING CONDITIONS There are no existing structures on site. This site is characterized by severe grade changes of up to 100', approximately 90% woodland coverage including over 830 significant trees, and several wetlands covering 6.84 acres. S_MOUNDING USES The following uses, zoning and comprehensive plan designations surround the subject property: North - Blue Cross/Blue Shield - Hwy 13; zoned PD; guided Limited Business South - Blackhawk Acres Townhomes; zoned R-3; designated D-III East - Single family; zoned R-1; designated D-I and D-III West - Undeveloped; zoned R-3; designated D-III EVALUATION OF REQUEST A. Comprehensive Plan Amendment The proposed amendment will shift an existing D-III/D-I boundary on the Land Use Guide Plan several hundred feet to the west. The requested amendment should not have a negative impact on the remaining D-III land in the area & Rezoning The proposed rezoning provides a westerly extension of the existing single family zoning and land use. This rezoning will create a new legal boundary between the subject site and the R-3 zoned property to the west but there are also physical boundaries. The majority of the site is separated from the neighboring property by Robin Lane and the remainder of the site is physically separated due to grade changes that prevent any logical connection. C. Prsliminary Subdivision The proposed 38 acre subdivision is split by Robin Lane; 35 lots on 23.4 acres on the north side and 25 lots on 14.5 acres to the south of Robin Lane. ~ atl'bii ity with Surrounding Area - The proposed subdivision will be compatible with existing single family development to the east and should be compatible with the established townhouse development to the south. The compatibility of the proposed development with the future development of the R-3 property to the west is less certain and will largely depend on the site design of any future development. Planning Report - Blackhawk Forest January 24, 1995 Page 4 Ui~c - As proposed, the gross density of the entire subdivision is 1.55 units/acre. The net density of the site (excluding 90% of wetland area and R-O-W) is 2.1 units/acre, which is also within the designated Guide Plan density of 0-3 units/acre. L= - All lots meet or exceed minimum lot size requirements of the R-1 zoning district. The 59 lots vary in size from 12,000 - 55,450 SF, with an average lot size of 25,126 SF. The applicant is proposing seven lots with an 80' minimum lot width which requires a 5' variance to the required 85' minimum lot width at the building setback line. According to the applicant, this variance to the lot width requirement will allow for some minor clustering of lots and preservation of more area in its present state. Setbacks - The applicant is requesting a blanket ten foot front building setback variance from 30' to 201. According to the applicant, the hardship for this variance request is that due to driveways and utilities, tree preservation is difficult in front yards; however, reducing the front setback to 20' will provide maximum tree preservation in the backyards. Grading/Wetlands - With revisions, the Grading Plan submitted is acceptable. Nine of 59 proposed lots will be custom graded. The developer has attempted to minimize disruption to the site as much as possible, which includes significant areas of the site that will not be disturbed with site preparation work and the construction of a 6 to 10 foot high retaining wall along the northerly edge of Red Fox Road. The Grading Plan should be revised to include detailed plans and specifications for the retaining wall construction. As proposed, the retaining wall is shown to be located in the public right-of-way of Red Fox Road. The City does not allow structures in public rights-of- way because of increased liability and maintenance obligations. There are several wetlands on site and the developer is proposing to fill certain areas and expand other areas. These wetlands include Pond AP-27, which is classified as a wildlife habitat. M The grading plan should be revised to provide a Moot freeboard from the lowest entry level of the houses abutting the ponds. Erosion could be a serious problem on this site because of the steep slopes. This developer will need to provide temporary sedimentation basins to collect and trap sediments before the overland water discharges into the existing wetlands. The temporary sedimentation basins would be removed after the vegetation is established on this site. Also, diversion dikes should be added to keep the off-site areas from draining across the disturbed areas of this site. V~ Planning Report - Blackhawk Forest January 24, 1995 Page 5 There are 8 wetland basins on the site with a total area of 6.84 acres. Staff have reviewed the wetland delineations completed by the developer's consultant and are in agreement with them. The site plan dated 12/29/94 calls for filling 8,515 square feet of wetland, or about 2.8% of the wetland area within the plat. There are several wetland-related issues associated with the site plan that will need to be resolved before the wetlands plan is acceptable. They are as follows: 1. the wetland mitigation area adjacent to Wetland Basin 3 should be dropped because it does not appear to meet Wetland Conservation Act criteria for the use of stormwater detention basins as wetland replacement. If needed, this mitigation area should be located adjacent to other basins in the plat that do not receive direct stormwater discharge. 2. Because they will be expanded to satisfy wetland replacement requirements, wetland basins 2, 5, and 6 should not receive any direct discharge from the storm sewer system. 3. The wetland replacement plan submitted with the plat application is incomplete. A correct and complete replacement plan must be received by staff no later than Wednesday January 25, 1995 in order to allow sufficient time for public review of the application prior to a City Council decision regarding approval of the plat on February 21, 1995. 4. There are several areas adjacent to wetland basins 2, 3, 5, and 10 where grading contours are shown up to the wetland boundary. These are areas where unintended wetland filling could occur in violation of the WCA. The developer should address specifically how unintended filling of wetland areas due to erosion will be prevented in these locations. 5. A 30 foot ungraded, natural buffer should be maintained from the edge of the NWL for Pond AP-27, and a 15 foot ungraded, natural buffer from the edge of wetland basins 5 and 6. Storm Drainage /Water OualiV - With modifications, the Storm Drainage Plan is acceptable. This area drains to an existing storm sewer line in Robin Lane which serves as the outlet for Blackhawk Lake and ultimately discharges directly into the Minnesota River Valley. There is also an existing storm sewer line that discharges into this site that drains Blackhawk Road and the Ridge View Acres development. The developer should be responsible for extending this line through the site to the storm water basin (wetland 3) that will be located in the backyards of Lots 22 and 23 of Block 2. A 5-acre portion of the site south of Robin Lane drains to Pond AP-38 (wetland 10), which is a classified as a nutrient basin in the City's Water Quality Management Plan. Tbere is Planning Report - Blackhawk Forest January 24, 1995 Page 6 an existing outlet for this pond that eventually drains to the storm sewer system that discharges directly into the Minnesota River Valley. All or portions of two water bodies identified in the City's water quality management plan He within the proposed plat. The first is Pond AP-27, located east of Robin Lane and classified for wildlife habitat. The second is Pond AP-38, located west of Robin Lane and classified as a nutrient trap. There are no downstream recreational water bodies. Staff has requested that the developer make the following changes to the site plan to meet water quality mitigation requirements: 1. Avoid discharging raw stormwater into Pond AP-27. 2. Rout the discharge from Pond AP-27 directly to the storm trunk in Robin Lane instead of to the proposed stormwater basin in wetland basin 3. 3. After, development of the site is completed, eliminate the pre-treatment basin adjacent to the wetland basin 3 stormwater treatment pond. 4. Increase the. wet pond volume of the stormwater treatment basin associated with wetland basin 3 by excavation as per water resources staff direction. 5. Rout raw runoff from Deer Pond Circle and the eastern segment of Brown Bear Trail to the proposed stormwater basin north of wetland basin 5. 6. The proposed pre-treatment basin for stormwater runoff that is located adjacent to Pond AP-38 should be eliminated, since it is very small and poorly located. The storm water runoff from the southerly segment of Brown Bear Trail should drain directly to Pond AP-38, which is a designated nutrient trap. Although the developer has expressed a willingness to work with staff to make these changes, a revised site plan incorporating these changes has not been submitted. The amount of the water quality cash dedication, if there is one, will depend oh the final configuration of the storm drainage system and ponding areas. 1Jtil1fies - With minor modifications, the Utility Plan submitted is acceptable. Sanitary sewer and water is available to serve this site from Robin Lane and Blackhawk Road The developer is proposing to abandon an existing sanitary sewer line that crosses through the backyard areas of Block 2 and relocate it to Red Fox Road Lots 1-5 of Block 2 were provided sewer and water services with the 1994 upgrade of Blackhawk Road; however, no service was installed for Lot 6. Providing services to this lot will require the removal and replacement of a portion of the new Blackhawk Road surface. Planning Report - Blackhawk Forest January 24, 1995 Page 7 Access/Street Design - As proposed, six lots have direct access to Blackhawk Road and nine lots have direct access to Robin Lane. The remaining 44 lots will take access from one of three proposed cul-de-sac streets. Two of the cul-de-sac streets, Red Fox Road and Brown Bear Trani, require variances to the maximum allowed cul-de-sac length of 500'. The cul-de- sac lengths requested are approximately 800' and 1,100' respectively. In both cases, there is no feasible alternate access available. Additionally, the applicant is requesting a variance to increase the maximum street grade from 8 to 9% for the proposed cul-de-sac south of Robin Lane (Brown Bear Vail). According to the applicant, this slight variance is necessary to allow the proposed street to climb the hill without exce ssive excavation. Easements fRig t-Of-Wav - The developer will need to vacate the existing easement over the existing sanitary sewer line that will be relocated to Red Fox Road. The developer should submit a petition to vacate this easement prior to final plat approval. The plat should be revised to include dedicated drainage and utility easements over the ponds and wetlands large enough to encompass an area 3 feet above. the high water level. Tree Preservation Policy - The Tree Preservation Plan submitted is acceptable. The site contains 834 significant trees as defined by the Policy. The developer has worked with staff to reduce the initial tree loss from 41.5 to 283 percent. The Policy allows initial site preparation (streets and utilities) tree removal of 25% and an additional 20% removal for home pad preparation; however, the developer is proposing a total removal of 283% for both phases (not including the 9 custom graded lots). Although the mitigation required for the 283 % is 72 category B trees, the developer is proposing replacement with 176 category A and B trees or 2.5 times what is required. Park Dedication - This site is located in Park Service Area 16. Skyhill park is the nearest park. Park land needs are met in this area and therefore, staff is recommending a cash park and trail dedication. =NCLUSION The proposed subdivision should be compatible with the existing and future development in the area The developer has worked with staff to protect the natural resources of the site and the variances requested are intended to serve the same purpose. City services are available to serve the site. Planning Report - Blackhawk Forest January 24, 1995 Page 8 AM70TO BE CONSIDERED Comprehensive Plan Amendment To recommend approval/denial of a Comprehensive Guide Plan amendment from D-III and LB to D-L Itezoning To recommend approval/denial of a Rezoning from R-3 and NB to R-1. Preliminary Subdivision and Variances To recommend approval/denial of the 59 lot Blackhawk Forest Preliminary Subdivision, subject to the conditions listed below. Standard Conditions 1. These standard conditions of plat approval as adopted by Council action on February 2, 1993, shall be complied with: Al, B1, B2, B4, C1, C2, C3, C4, Dl, El, Fl, Gl, and Hl. Subdivision 2. A variance of ten feet to the front yard setback for all lots. 3. Five foot lot width variance for Lots 2, 3, 5, and 6, Block 1, Lot 18, Block 2, and Lots 13 and 14, Block 3. 4. A variance to allow a 9% maximum street grade for Brown Bear Trail. 5. Variances to allow two cul-de-sac streets exceeding the maximum length of 500 feet. 6. All corner lots shall take access from the cul-de-sac street. 7. The developer shall provide detailed retaining wall plans and specifications. 8. The proposed retaining wall cannot be located within any dedicated public right-of- way. lPb . Planning Report - Blackhawk Forest January 24, 1995 Page 9 Mree Preservation 9. The developer shall install fencing at the critical root zone (a distance of one foot away from the tree trunk for every inch in diameter as measured 54" above grade) amuad all trees depicted on the Tree Preservation Plan to be saved. 10. The developer shall contact the City so an inspection can be performed of the . preventive measures installed prior to any site grading, trenching, filling, compaction, or change in soil chemistry taking place. 11. The developer shall provide 176 category A and B trees for tree preservation mitigation. Water Qualily.1 ft l n _ 12. The developer shall provide a 30 foot natural, ungraded buffer strip along the edge of Pond AP-27, and a 15 foot ungraded, natural buffer from the edge of wetland basins 5 and 6. 13. The wetland mitigation area adjacent to Wetland Basin 3 should be dropped because it does not appear to meet Wetland Conservation Act criteria for the use of stormwater detention basins as wetland replacement. If needed, this mitigation area shall be located adjacent to other basins in the plat that do not receive direct stormwater discharge. 14. Because they will be expanded to satisfy wetland replacement requirements, wetland basins 2, 5, and 6 shall not receive any direct discharge from the storm sewer amen 15. The wetland replacement plan submitted with the plat application is incomplete. A correct and complete replacement plan must be received by staff no later than Wednesday January 25, 1995 in order to allow sufficient time for public review of the application prior to a City Council decision regarding approval of the plat on February 21, 1995. 16. 7kre are several areas adjacent to wetland basins 2, 3, 5, and 10 where grading contours are shown up to the wetland boundary. These are areas where unintended wetland filling could occur in violation of the WC'A. The developer shall address specifically how unintended filling of wetland areas due to erosion will be prevented in these locations. 17. A 30 foot ungraded, natural buffer shall be maintained from the edge of the NWL of Pond AP-27, and a 15 foot ungraded, natural buffer from the edge of wetland basins 5 and 6. Planning Report - Blackhawk Forest January 24, 1995 Page 10 18. Avoid discharging raw stormwater into Pond AP-27. 19. Rout the discharge from Pond AP-27 directly to the storm trunk in Robin Lane instead of to the proposed stormwater basin in wetland basin 3. 20.
