HomeMy WebLinkAbout9A - Jeffers Pond CITY COUNCIL AGENDA REPORT 16200 Eagle Creek Avenue S.E. Prior Lake, MN 55372-1714 MEETING DATE: AGENDA #: PREPARED BY: AGENDA ITEM: DISCUSSION: JANUARY 3, 2005 9A JANE KANSIER, PLANNING DIRECTOR CONSIDER APPROVAL OF A RESOLUTION MAKING A NEGATIVE DECLARATION ON THE NEED FOR AN ENVIRONMENTAL IMPACT STATEMENT FOR THE JEFFERS POND DEVELOPMENT Historv: Wensmann Realty, Inc. and Paul Oberg, Executor of the Jeffers Estate, are proposing to develop 336 acres of land located at the southwest quadrant of the intersection of CSAH 42 and CSAH 21. The proposed development includes 693 housing units consisting of a wide variety of home ownership options including senior apartment rental units, townhomes, condominiums, twinhomes, and single-family homes. In addition to the residential component, the project also includes approximately 24 acres of developable commercial area. The proposed development will also provide several public use facilities, including a future elementary school, fire station, and a transit station. The number of proposed dwelling units included within the project triggered the need for a mandatory Environmental Assessment Worksheet (EA W) under Minnesota Rules 4410.4300, subp. 19. Under Minnesota Rules, the City Council is designated as the Regulatory Governmental Unit (RGU) charged with preparing and making the decisions on the EA W. The City hired Liesch Associates to prepare the EA W on its behalf. The EA W was completed in November and distributed to the Environmental Quality Board (EQB) mailing list and other interested parties on November 8, 2004. Notice of the EA W was also sent to the Prior Lake American on November 6, 2004, and published in the EQB Monitor on November 8, 2004. The comment period on the EA W expired on December 8, 2004. Comment letters were received from the Metropolitan Council, the Army Corps of Engineers and the Minnesota Department of Natural Resources. Copies of the letters and the responses to these comments are attached to this report. www.cityofpriorlake.com 1.\64 fi.l,",~\84 t:)ubd~v~t:)~Vlli:)\\64 pl,.J~JJl plaf~~ff""'lt:) PVlld'"...,aVV'\\,..\" .\",puILdv\" Phone 952.447.4230 / Fax 952.447.4245 F (115'" 1 Current Circumstances: Minnesota Rules 4400.1700, subp. 2, requires a decision on the need for an EIS be made within 30 days of the expiration of the comment period. The decision must be based on the following criteria: a) The type, extent and reversibility of environmental effects; b) The cumulative potential effects of related or anticipated future projects; c) The extent to which the environmental effects are subj ect to mitigation by an ongoing public regulatory authority; d) The extent to which the environmental effects can be anticipated and controlled as a result of other environmental studies undertaken by public agencies or the project proposer, or ofEIS's previously prepared on similar projects. Each of these criteria is discussed in detail in the attached Exhibit A labeled "Findings of Fact and Conclusions." The Issues: The major issues identified in the EA Wand in the comments submitted pertain to the runoff generated by this development, the impacts of the traffic generated by the development and the impacts on the wetlands on the site. The infrastructure needs, storm water management needs and wetland mitigation were all analyzed and determined based on the maximum build-out of the site, per the City of Prior Lake Zoning Ordinance. Any further subdividing of the project site would not create any additional infrastructure needs, impervious surfaces or additional storm water management needs. Therefore, all cumulative impacts have been analyzed. A primary element of the proposed Project is the adequate control and treatment of surface water runoff, both with regard to on-Site wetland quality and the Prior Lake outlet channel that runs through the property within the Watershed easement. The City and the Watershed have requirements to restrict post-development storm water rates and these requirements were taken into consideration in preparation of the Storm Water Management Plan. Increased traffic resulting from the Project as well as other adjacent development in the City will increase noise. The overall proposed Project layout situates the retail and commercial development nearest to the major roadway intersection, CSAH 42 and CSAH 21, where noise levels are expected to be highest and situates institutional development (elementary school and fire station) along CSAH 21. Residential units are generally situated at greater distance from the major roads. 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\cc report.doc Page 2 The results of the noise analysis indicate that, considering the worst- case scenario, some proposed residences in close proximity to portions ofCSAH 21 are predicted to be above State standards. Incorporation of berms and other landscaping as mitigative measures will be required to reduce the noise levels to below State standards. At the public hearing, the Planning Commission heard testimony about the potential noise impacts of this development on the Carriage Hills development on the east side of CSAH 21. The City Council heard these same concerns at the public forum on December 20,2004. Aerial photographs indicate there were some trees removed along the east side ofCSAH 21, probably for the road project. The staffhas contacted the Scott County Highway Department to obtain more information on this project. This development will have some impact on the traffic levels and noise levels in the area, especially during construction. However, the traffic study notes even without construction of this project (no-build conditions) the traffic and noise levels on CSAH 21 will increase by the year 2009. Build-out conditions result in a 1 decibel increase in the anticipated noise levels from the no-build conditions. The proposed development does not significantly impact the anticipated noise levels. The EA W has also determined the potential traffic generated as a result of this development will impact the turning movements on CSAH 21 at the Fountain Hills intersection and on CSAH 42 at the new McKenna Road intersection. In order to mitigate this impact, the developer will be required to contribute in the cost of the construction of turn signals at the CSAH 21 and Fountain Hills intersection and an escrow for this purpose will be set out in the Development Contract. When Scott County determines the signal is needed, these funds will be utilized for that construction. The nature and the amount of the contribution will be determined as part of the final plat and development contract approval process. The total wetland fill proposed for the proj ect is 1.07 acres combined from 17 individual areas. Compensatory wetland mitigation of 1.08 acres of new wetland and 1.07 acres of public value credits is proposed on site. Additional wetland mitigation is required to account for the required 2: 1 replacement ratio. For the Project the replacement ratio is met by utilizing a portion of the Public Value Credit created by the storm water ponds and associated wetland buffer areas. Wetland filling will be mitigated through on-site wetland mitigation and use of existing banked credits. This project is also subject to permit review and approval from several other agencies, including the Army Corps of Engineers, the Minnesota Pollution Control Agency, the Minnesota Department of Health, the Scott County Highway Department and the Prior Lake-Spring Lake 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\cc report.doc Page 3 FISCAL IMPACT: ALTERNATIVES: RECOMMENDED MOTION: REVIEWED BY: Watershed District. These permits will assess the impacts of the project based on current statutes. These permits will only be issued after a negative declaration on the EA W, and after City approval of the development. Conclusion: All comments from the state and local agencies note an EIS is not necessary for this development. The environmental impacts of this project will be addressed through the standard permitting process. The staff therefore recommends the City Council make a negative declaration on the need for an EIS. BudJ!et Imoact: There is no budget impact as a result of this action. The City Council has two alternatives: I. Adopt a resolution making a negative declaration on the need for an EIS for this project. 2. Determine there is a need for further environmental review of this project. In this case, the Council must direct the staff to prepare a resolution declaring the need for an EIS based on specific findings of fact. rnative # I.

EXHIBIT A Prior Lake, MN 55372-1714 FINDINGS OF FACT AND CONCLUSIONS IN THE MATTER OF THE DECISION ON THE NEED FOR AN ENVIRONMENTAL IMPACT STATEMENT (EIS) FOR THE PROPOSED JEFFERS POND DEVELOPMENT Wensmann Realty, Inc. and Paul Oberg, Executor of the Jeffers Estate, are proposing to develop 336 acres of land located at the southwest quadrant of the intersection ofCSAH 42 and CSAH 21. The proposal calls for a mixed-use development consisting of retail space and offices, single family homes, residential condominiums, townhomes, senior apartments, an elementary school site, a fire station site, transit station site, and parks and trail on a total of 336 acres. Pursuant to Minn. R. 4410.4300, subp. 19, the City of Prior Lake has prepared an Environmental Assessment Worksheet (EA W) for this proposed proj ect. As to the need for an Environmental Impact Statement (EIS) on the project and based on the record in this matter, including the EA Wand comments received, the City of Prior Lake makes the following Findings of Fact and Conclusions: Findings of Fact I. PROJECT DESCRIPTION A. Project The Jeffers Pond Development consists of 336 acres of undeveloped land located in the southwest quadrant of Highway 21 and County Road 42 in Prior Lake, Minnesota. The proposed development includes 693 housing units consisting of a wide variety of home ownership options including senior apartment rental units, townhomes, condominiums, twinhomes, and single-family homes. In addition to the residential component, the project also includes approximately 24 acres of developable commercial area. The proposed development will also provide several public use facilities, including a future elementary school, fire station, and a transit station. B. Project Site The proposed Jeffers Pond project is situated within 336 acres of land located in the southwest quadrant of County Highway 42 and County Highway 21 in the City of Prior Lake (referred to as "Jeffers Pond site" or "Site"). The Site is currently undeveloped with the exception of a farmstead located near the northwestern corner of the Site. Currently the Site includes agricultural land, 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\findi,ng~.doIC k WWW.cltyotpnorae.com Page 1 Phone 952.447.4230 / Fax 952.447.4245 mature woodland areas and wetlands. Adjacent land use includes existing residential development to the south of the Site as well as east of the southern two-thirds of the Site. West of the Site is the Wilds Golf and Country Club and to the north, across County Road 42, is agricultural land, portions of which are currently under development by a church. II. PROJECT HISTORY A. This project was subject to the mandatory preparation of an EA Wunder Minnesota Rules. 4410.4300, subp. 19. B. An EA W was prepared on the proposed project and distributed to the Environmental Quality Board (EQB) mailing list and other interested parties on November 8, 2004. C. A press release containing the notice of availability of the EA W for public review was sent to the Prior Lake American on November 6,2004. D. The EA W was noticed in the November 8, 2004, EQB Monitor. The public comment period ended on December 8, 2004. Comment letters were received on or before the deadline from the Metropolitan Council, the Department of the Army - Corps of Engineers St. Paul District and the Minnesota Department of Natural Resources. Copies of the letters are hereby incorporated by reference. Responses to the comments are also incorporated by reference. III. CRITERIA FOR DETERMINING THE POTENTIAL FOR SIGNIFICANT ENVIRONMENTAL EFFECTS Minnesota R.441 0.1700, subp. 1 states that "an EIS shall be ordered for projects that have the potential for significant environmental effects." In deciding whether the project has the potential for significant environmental effects, the City of Prior Lake must consider the four factors set out in Minnesota R.4410.1700, subp. 7. With respect to each of these factors, the City finds as follows: A. TYPE, EXTENT, AND REVERSffilLITY OF ENVIRONMENTAL EFFECTS The first factor that the City of Prior Lake must consider is "type, extent and reversibili ty 0 f environmental effects," Minnesota R.441 0.1 700, subp. 7.A. The City's findings with respect to each of these issues are set forth below. 1. The type of environmental impacts anticipated as part of this project includes: a. Increased municipal water use Increased water use will be accommodated by the expansion of the existing watermain trunk system. 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\findings.doc Page 2 -~----_._.....__._._..~.._... .-." ..-......i.....-.... .-o._.~.. ".... .......... ....-.".,_... ~..._._-._._..... ,,' ......-...-........... ._... -....-.......,,".----. b. Increased wastewater discharge All of the wastewater will be typical sanitary sewage from residential and commercial uses. The additional wastewater will be treated at the Metropolitan Council Environmental Services Blue Lake Treatment Plant. This plant has the capacity to accommodate the additional discharge. c. Increased noise due to traffic within the area Noise will be that typical of residential communities and as associated with a school and fire station. Thus, noise associated with the completed project will be similar to surrounding residential (existing or future) areas. Noise mitigation is provided by site layout and tree plantings. The primary potential noise impact would occur with traffic at major intersections during peak traffic hours on CSAH 21 and 42. Noise impacts would be least on the western side of the wooded ridge. Minnesota Statue 116.07 Subd. 2a. states that municipal and county roads (except in Minneapolis and St. Paul) are exempt from the noise standards, and therefore the City and County roads associated with the Project are exempt. Increased traffic resulting from the Project as well as other adjacent development in the City will increase noise. The overall proposed Project layout situates the retail and commercial development nearest to the major roadway intersection (CSAH 42 and CSAH 21) and additionally situates institutional development (elementary school and fire station) along CSAH 21. Residential units are generally situated at greater distance from the major roads. The results of the noise analysis indicate that, considering the worst-case scenario, some proposed residences in close proximity portions of CSAH 21 are predicted to be above State standards. Incorporation of berms and other landscaping as mitigative measures are anticipated to reduce the noise levels to below State standards. d. Wetland impacts from filling The total wetland fill proposed for the project is 1.07 acres combined from 1 7 individual areas. Compensatory wetland mitigation of 1.08 acres of new wetland and 1.07 acres of public value credits is proposed on site. Additional wetland mitigation is required to account for the required 2: 1 replacement ratio. For the Project the replacement ratio is met by utilizing a portion of the Public Value Credit created by the storm water ponds and associated wetland buffer areas. Wetland filling will be mitigated 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\findings.doc Page 3 through on-site wetland mitigation and use of existing banked credits. e. Increased stormwater runoff rate and volume. Stormwater management for the completed Project proposes 12 storm water retention ponds (National Urban Runoff Program or NURP ponds) 12 infiltration basins and eight combination ponds to control the rate of runoff. These runoff controls require review and approval of the City and Watershed. Considerations used to locate and design the capacity of these erosion and sedimentation control measures includes catchment area, runoff rates and infiltration rates from different surfaces, under varying storm event scenanos. A primary element of the proposed Project is the adequate control and treatment of surface water runoff, both with regard to on-Site wetland quality and the Prior Lake outlet channel that runs through the property within the Watershed easement. The City and the Watershed have requirements to restrict post-development storm water rates and these requirements were taken into consideration in preparation of the Storm Water Management Plan. The Storm Water Management Plan notes that restricting flows through the numerous wetlands on the Jeffers Pond site is important to minimizing erosion of the downstream channel, and also allows the Watershed to maintain lake levels in Prior Lake by allowing the targeted discharge rates to be achieved. To this extent some improvements are proposed to existing culverts along the drainage and flowage easement. 2. In general, the extents of the environmental impacts are consistent with those of a residential and commercial development. B. CUMULATIVE POTENTIAL EFFECTS OF RELATED OR ANTICIPATED FUTURE PROJECTS The second factor that the City of Prior Lake must consider is "the cumulative potential effects of related or anticipated future projects", Minnesota R.441 0.1700. supb. 7.B. The City's findings with respect to this factor are set forth below. 1. The construction of the Jeffers Pond Development will be in phases over the next 5 years based on the local demand for these uses. The use of Best Management Practices and the NPDES General Stormwater Permit will be implemented and maintained throughout all construction phases of these projects to ensure the effects of erosion and sedimentation are mitigated. The property directly to the west is part of The Wilds Residential 1:\04 fiJes\04 subdivisions\04 prelim plat\jeffers pond\eaw\findings.doc Page 4 Development and is substantially complete. The property to the south is also substantially developed with residential units. 2. The EA W has also determined the potential traffic generated as a result of this development will impact the turning movements on CSAH 21 at the Fountain Hills intersection and on CSAH 42 at the new McKenna Road intersection. In order to mitigate this impact, the developer will be required to contribute in the cost of the construction of turn signals at the CSAH 21 and Fountain Hills intersection. When Scott County determines the signal is needed, these funds will be utilized for that construction. The nature and the amount of the contribution will be determined as part of the final plat and development contract approval process. 3. In general, the City finds the cumulative impacts of this development can be mitigated by the above conditions. C. THE EXTENT TO WHICH ENVIRONMENTAL EFFECTS ARE SUBJECT TO MITIGATION BY ONGOING PUBLIC REGULATORY AUTHORITY 1. The following permits or approvals will be required for the project: Unit of Government Federal Army Corps of Engineers State: MPCA MPCA/MCES MN Dept. of Health Local: City of Prior Lake City of Prior Lake LGU - Prior Lake Scott County Prior Lake-Spring Lake Watershed District Permit or Approval Required Wetland Mitigation Permit NPDES Permit; General Storm Water Permit Sanitary Sewer Permit Water Extension System Grading and platting plan approval Building Permit/Sign Permits Wetland Impact for Wetland Conservation Act Access/R -0- W Stormwater Management Plan 2. The City finds that the potential environmental effects of this project are subject to mitigation by ongoing regulatory authorities; therefore, an EIS need not be prepared. D. THE EXTENT TO WHICH ENVIRONMENTAL EFFECTS CAN BE ANTICIPATED AND CONTROLLED AS A RESULT OF OTHER ENVIRONMENTAL STUDIES UNDERTAKEN BY PUBLIC AGENCIES OR 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\findings.doc Page 5 '_._.,_._......,........._.......~',_._._._.,,__......~.''''_..''~'"_...'-,..,._.'"^''",..._._,~... .'"""_~"'......"..,"_~~_.,"'.."'-~~_........._."'>,,_....,~.,<.. -,. _,," .._..'-,~~_~._...."'_;._._;".~_"""""""_._...M.".'"_-'__"._....~,""....._ THE PROJECT PROPOSER, OR OF EIS's PREVIOUSLY PREPARED ON SIMILAR PROJECTS. The fourth factor that the City must consider is "the extent to which environmental effects can be anticipated and controlled as a result of other environmental studies undertaken by public agencies or the project proposer, or of EIS's previously prepared on similar projects," Minnesota R.4 700.1700, subp. 7.D. The City's findings with respect to this factor are set forth below: The environmental impacts of the proposed project have been addressed in the following plans: 1. City of Prior Lake Comprehensive Plan 2. City of Prior Lake Comprehensive Local Surface Water Management Plan 3. Traffic Impact Study for the Jeffers Pond Development 4. Jeffers Pond Stormwater Management Plan The City finds the environmental effects of the project can be anticipated and controlled as a result of the environmental review, planning, and permitting processes. CONCLUSIONS 1. The preparation of the EA Wand comments received on the EA W have generated information adequate to determine whether the proposed development has the potential for significant environmental effects. 2. The EA W has identified areas where the potential for significant environmental effects exist. Appropriate mitigative measures have been incorporated into the project plan with respect to utilities, wetlands, traffic, noise and stormwater runoff. The Jeffers Pond development is expected to comply with all City of Prior Lake standards and review agency standards. 3. Based on the criteria established in Minnesota R.4410.1700, the potential impacts of this project can be addressed through the regular permitting process. 4. An Environmental Impact Statement is not required. 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\findings.doc Page 6 Jeffers Pond Environmental Assessment Worksheet (EA W) Response to Comments January 3, 2005 Comments received by the City of Prior Lake from the 30-day public comment period (November 8, 2004 through December 8, 2004) for the proposed Jeffers Pond Development project are summarized below and provided with a corresponding response. Metropolitan Council (District 4" Review file No. 19354-1) Review comments provided by the Metropolitan Council indicated that, the EA W was complete, and that an environmental impact statement (EIS) was not necessary for regional purposes. Therefore the Council indicated they would take no formal action on the EA W. Specific comments were provided on two items as follows. · Item 16 Erosion and Sedimentation: the City and proposer are encouraged to continue to work with the Spring Lake - Prior Lake Watershed District to protect a 50-foot setback buffer area around Jeffers Pond to protect existing bluffs and steep slopes Response: The importance that Jeffers Pond and other wetlands have to water management both for the watershed and on the Property is acknowledged, and has been an issue of importance to proposed project planning to date. Review and approvals are required through the permitting processes of the City, the Prior Lake - Spring Lake Watershed District, and Corps of Engineers. . Item 18: Water Quality: Wastewater: The presence of the Metropolitan Council Environmental Services (MCES) Interceptor (#7120) through portions of the property is identified, and it is requested that final site plans be forwarded to the MCES Interceptor Engineering Manager (Scott Dentz 651-602-4503) prior to initiating the proj ect. Response: The importance of properly planning for all work associated with or in the vicinity of the sewer interceptor is acknowledged. Department Of The Armv - Corps of Eneineers St. Paul District The review comments provided by the Corps of Engineers St Paul District office pertains to wetland management in association with the proposed project and the Department of Army permitting that will be required. Reference is also made to a November 16, 2004 Technical Evaluation Panel (TEP) meeting regarding the project during which wetland issues were discussed. 1:\04 files\04 subdivisions\04 prelim plat~effers pond\eaw\responses\response to comments.doc ... ..., ..- -.~'"'I----''-.''''''' . . The written comments emphasize the following items: 1) A Department of Army permit will be required because of the planned excavation, grading, and/or re-sloping proposed. 2) The permit application should document the alternatives evaluated and the efforts to avoid and minimize wetland impacts. 3) The Corps of Engineers regulations for mitigation requires a 1.5 to 1 ratio of created or restored wetlands and notes that the ratio can be adjusted based on the quality of the resources. 4) The Corps of Engineers does not acknowledge mitigation credit for the construction of storm water ponds. 5) Corps approval of mitigation plans will be necessary before granting any permit. Response: It is understood an application to the Corps of Engineers for a Department of Army permit is required and will need to be complete and that a copy of the wetland delineation report, in its entirety and with associated field data sheets, should be attached to the application. The mitigation criteria of the Corps of Engineers is noted as being 1.5 to 1 and that Public Value Credits, as allowed by the Minnesota Wetland Conservation Act, may not apply to the Corps requirements. The Corps of Engineers requirement will result in an additional 0.54 acres of new wetland. Final wetland mitigation requirements and measures will be established with the various agencies that have jurisdiction through the permitting process and the Technical Evaluation Panel. The developers have been notified of these requirements and are aware that no grading permit will be approved until all of the wetland issues have been satisfied. Minnesota Department of Natural Resources From a natural resources perspective, the Department of Natural Resources (DNR) review comments note that the EA W is complete and accurate. Comments to five items within the EA Ware offered by the DNR for consideration. . Cover Type (Item No. 10): For the proposed removal of 31 acres of wooded/forest cover, the DNR strongly recommends that the beneficial use of these resources be considered as part of the project planning process. Advice can be provided by the DNR's Regional Forest Utilization and Marketing Specialist (651 772-7567). Response: The comment is noted and shall be reiterated to the proposer. . Physical Impacts on Water Resources (Item No. 12): The reclassification of Jeffers Pond from a Natural Environment Lake to a Recreational Lake by the DNR in 2002 is pointed out as having implications on not only set-back distances, but also on site density within the shoreland district. A greater density is allowed by the revised Recreational classification. Response: The DNR is correct. The impacts of the additional density are offset by the 50' buffer around Jeffers Pond, and the preservation of a natural open space as a natural park. 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\responses\response to comments.doc 2 . Water-related Land Use Management Districts (Item No. 14): The DNR points out that review of the project as a Planned Unit Development (PUD) allows for greater development density. Also, the DNR states that it does not support the granting of variances for setbacks from bluffs or the ordinary high water mark, or deviation from impervious surface and building height requirements. As the reclassification of Jeffers Pond allows for greater development density (over the previous Natural Environment Lake classification), the DNR does not support shoreland variances for the project. Response: A greater density is allowed by the PUD approach, which may also be beneficial for addressing site-specific situations associated with the property. The DNR's comments regarding deviations from established setbacks, impervious surface area, building height, etc., are noted. The DNR reclassification approval letter (October 31, 2002) promoted the use of the Natural Environment setback of 150 where possible, incorporation of a 50 or 60 foot publicly owned buffer strip, and maintaining natural steeper slopes and trees to the extent possible. In this regard it is noted that the Prior Lake - Spring Lake Watershed District has an easement through the property for Jeffers Pond and the Prior Lake outlet. The 50' buffer will also be dedicated to the City for public purposes. The City will retain control over this area. . Water Surface Use (Item No. 15): The DNR suggests that the City insure the prohibition of motorized watercraft and private docks on Jeffers Pond (as required by the reclassification approval) with an amendment to the City's surface water ordinance. Response: The DNR letter regarding reclassification of Jeffers Pond indicates that the reclassification includes surface water controls by the City that will prohibit motorized watercraft or private docks. The City will enforce and evaluate amending the surface water ordinance with this specific stipulation. Since the City also has control over the accesses to Jeffers Pond, the type of watercraft will be within City control. . Erosion & Sedimentation (Item No. 16): The DNR recommends that home construction not be allowed into bluff areas and that steep slopes around Jeffers Pond be stabilized but not flattened as currently proposed. Response: The developer has been advised that grading will not be permitted within the 50' buffer around Jeffers Pond, other than to establish a trail. 1:\04 files\04 subdivisions\04 prelim plat\jeffers pond\eaw\responses\response to comments.doc 3 12/08/04 14:51 FAX 651 602 1674 METRO COUNCIL 14I 002 ~ Metropolitan Council December 8, 2004 Jane Kansier, Planning Director City of Prior Lake 16200 Eagle Creek Avenue SE Prior Lake, MN 55372-1714 RE: City of Prior Lake Environmental Assessment Worksheet (EA W) Jeffers Pond Metropolitan Council District 4 Metropolitan Council Review File No. 19354-1 Dear Ms. Kansier: Thank you for submitting the Jeffers Pond Environmental Assessment Worksheet (EA W) to the Metropolitan Council for review. Jeffers Pond is a proposed mixed-use development on 336 acres located in the northern part of the City. The project includes office space, retail, and 693 residential units ranging from single-family to townhomes. Our staff is responsible for reviewing the EA W to determine whether it adequately and accurately addresses regional concerns. The Council staff finds that the EA W is complete, and an environmental impact statement (EIS) is not necessary for regional purposes. The Council will take no formal action on the EA W. However, we offer the following comments: Item 16: Erosion and Sedimentation The EA W states that the site has bluffs and steep slopes in several locations, and that these slopes may be reduced to minimize erosion potential. The Council staff encourages the City to continue to work with Spring Lake Watershed District and the developer to protect bluffs where feasible, and to protect the 50- foot setback area (buffer) around Jeffers Pond. hem18:WarerQuaU~:Wasuw~en The Metropolitan Council's Interceptor #7120, located south of County Road 42, and west of County Road 21, intersects the proposed project. To ensure the integrity of the MCES interceptor, the City should forward fmal plans to Scott Dentz, MCES Interceptor Engineering Manager (651 602-4503) for review conunent prior to initiating the project.

Prior Lake, MN 55372 Re: Jeffers Pond Environmental Assessment Worksheet (EA W) Dear Ms. Kansier: We have reviewed the Environmental Assessment Worksheet prepared for the Jeffers Pond Development to construct a mixed-use commercial and residential development on 336 acres located in Section 27, T. 115 N., R. 22 W., Scott County, Minnesota. Although some of the following comments may have been addressed at a TEP panel meeting with the Army Corps of Engineers on November 2004, we would like to emphasize the following points regarding the Department of the Army permitting process and required compensatory mitigation: ~ A Department of the Army permit will be required for this proposed development project because of its adverse impacts to wetlands pursuant to Section 404 of the Clean Water Act. Adverse impacts may include the discharge of dredge or fill material in waters of the US, including wetlands, and excavation and resloping/ grading of material from these waters/wetlands. If this project includes any temporary placement of excavated material in waters/wetlands, this project may also require appropriate authorization for that work.. >- Any application submitted should clearly document what efforts have been taken to avoid, and minimize wetland impacts. The application should also thoroughly discuss what alternatives were considered and why those were not chosen. >- The Army Corps of Engineers regulations pertaining to wetland mitigation require a no net loss of wetlands, based upon their functions and values. The St. Paul District requires a 1.5 to 1 ratio of created or restored wetlands for mitigation as a reference point or baseline. The ratio could be adjusted dependent upon the quality of the existing resources, -.,,"'-,_.__..+-~._.,'--, ''-.-"-..-..-I--.'----'"--~--,...---_...__.._-,. - - ., - --..~._-~..-....~.....-.-.,.....---.-"----,--.--.-.~..-.---------.----..----------.- location of the mitigation site or the anticipated values of the replacement areas. ~ Excavating in wetlands and grading the slopes for stormwater ponds will likely need to be mitigated too. The Corps of Engineers does not acknowledge any mitigation credit for the construction of stormwater ponds. ~ The Corps will review and approve any proposed mitigation plan to offset the permanent adverse impacts to wetlands before granting any permit. ~ Before or at the time when submitting an application for this project we would like you to include a complete copy, including all field data sheets of the 1998 wetland delineation report and its 2003 review.

Prior Lake, MN 55372-1714 RE: Jeffers Pond Development Environmental Assessment Worksheet (EA W) Dear Ms. Kansier: The Department of Natural Resources (DNR) has reviewed the EA W for the proposed Jeffers Pond Development in the City of Prior Lake. Prom a natural resources perspective, the document appears to be complete and accurate. We offer the following comments for your consideration. Cover Tvoes (Item No. 10) The table shows the conversion of 31 acres of wooded/forest cover. This will result in the removal of a significant amount of wood from the site. Depending on the condition of this wood, the project proposer may elect to market it as sawlog, landscaping material, firewood, or bio-fuel for the production of energy. We strongly recommend that the City contact Jean Mouelle, Regional Forest Utilization and Marketing Specialist (651 772-7567), for advice on this subject. Physical Impacts on Water Resources (Item No. 12) This item discusses the reclassification of the shoreland zoning designation for Jeffers Pond from a Natural Environment Lake to a Recreational Development Lake. The EA W states that this reclassification has implications on the setbacks for the site. Of equal or greater importance are the site density implications for within the shoreland district. Greater density is allowable under the Recreational Development classification than under the Natural Environment classification. Water-related Land Use Management Districts (Item No. 14) The document states that the city agreed to review the project as a Planned Unit Development (PUD) because of the steep site topography. Another reason for PUD review is that the PUD designation allows for greater development density than do the requirements for standard development. This item also briefly touches on "proposed deviations" (variances) from City ordinances for several items, including setbacks and construction extending into bluff areas. The DNR does not support the granting of variances for setbacks from bluffs or the Ordinary High Water mark. Additionally, we recommend that the development adhere to the impervious surface and height requirements of the An Equal Opportunity Employer Who Values Diversity DNR Information: 651-296-6157 1-888-646-6367 TTY:' 651-296-5484 1-800-657-3929 -...-.-.--..-----.-......-. --..--....-........ ._....--..T.--~................. .... ..........--... '-"'"'"'' .....- .... ....._._~-_._...._.. .....--....-.. .....~....... ..--...... ....... December 8,2004 Page 2 shoreland ordinance. In light of the reclassification of Jeffers Pond, the DNR likely would not support shoreland variances, particularly for new development. We would expect that multi-level parking ramps in a shoreland area would meet the shoreland structure height requirements. Water Surface Use (Item No. 15) The DNR understands that, as part of the approval of the reclassification, the city would prohibit motorized watercraft from Jeffers pond and not allow private docks. The most effective way to ensure this is through an amendment to the city's surface water use ordinance. Erosion & Sedimentation (Item No. 16) The DNR recommends that the city not allow home construction to extend into the bluff area and require that the steep slopes around Jeffers Pond be stabilized as necessary, but not flattened as proposed. Thank you for the opportunity to review this project and the EA W. We look forward to receiving your record of decision and responses to comments at the conclusion of environmental review. Minnesota Rules part 4410.1700, subparts 4 and 5, require you to send us your Record of Decision within five days of deciding on this action.
