If the comment is editorial or advisory, we have acknowledged the comment and any necessary correction(s) to be made to the AUAR document. For comments that are substantive, we have replied and where necessary, referenced appropriate sections of the Draft AUAR. Revisions to Tables, Figures and text are included in Appendix B. Minnesota Department of Natural Resources Comments 1. Pagel, .Paragraph 2 "Figure 5 -3 PUD Concept Plan, does not illustrate units located on the Apple Valley portion of the site," Respons A current Concept Plan which includes the 56 units located on the Apple Valley portion of the site is included in Appendix B of this document. Thank you for noting this omission in the Draft AUAR. 2. Page 1, Para 3 "Item 6, Description -The project description describes housing densities after construction. What would be the overall housing density with wetland areas deducted ?" Response: The Draft AUAR notes that the AUAR area is proposed to contain an overall net density of 2.8 units to the acre, based on a land area of 465 net acres (gross acreage of the site is 535 acres). Forty -two acres of wetlands have been identified on the site. If the 42 acres are subtracted from 465 developable acres, 423 acres remain, giving an average density of 2.9 units per acre. 3. Page 1 Parag 4 "Item 11, Fisheries Resources — In the past, the D;M1R has considered using Birger Pond for game fish rearing, and would consider it again if the opportunity arose. After development, local angling demand might develop for angling on the property. Providing this opportunity may not be physically possible or ecologically sound." Final AUAR — Kelley Trust Property F Response: This informational comment will be added to Item 11 in the Final AUAR, 4. Page 1. Paragraph 5 and b "Item 12, Physical Impacts on Water Resources — The AUAR states that "Final site plans and grading plans will identify the wetlands that will be affected and degree of impact." Plans should also indicate how impacts will be avoided or maintained below levels established in the City's Wetland Management Plan. We recommend that buffers around wetlands be clearly delineated and marked with corner markers or monuments at lot corners to make them visible and to aid enforcement of the buffer requirements." I Response. The developer and City agree to implement these recommendations. The statement, "Site plans will indicate methods that will be used to avoid impacts to wetlands and meet the requirements of the City's Wetland Management Plan. Buffers around wetlands will be clearly delineated with corner markers or monuments at lot corners to make them visible and to aid enforcement of the buffer requirements," will be added to the Final AUAR. "The City has a Protected Waters permit pending for a pumped outlet from Birger Pond. The DNR expects to be able to issue the permit shortly." Response: This informational statement will be added to the Final AUAR under Item 12. 5. Page 1, Pa rma h "Item 14, Water - Related Land Use Management Districts — The west portion of the site, located in Apple Valley, lies within the shoreland district of Farquar Lake. Development within the shoreland district (1000 feet from Farquar Lake) must comply with Apple Valley's shoreland ordinance. There is no shoreland district in the Rosemount portion of the project." Response: We will add the information in this paragraph to the Final AUAR under Item 14. A statement will be included as follows: "The west portion of the site, located in Apple Valley, lies within the Shoreland District of Farquar Lake. Development within. the shoreland district (1000 feet from Farquar Lake) will comply with Apple Valley's Shoreland Ordinance. There is no Shoreland District in the Rosemount portion of the project." Final AUAR —Kelley Trust Property 6 6. Page 2. Paragraph I "Item 17, Erosion and Sedimentation – The majority of the site contains highly erodible soils, and steep slopes are numerous. Development of, and strict adherence to, a detailed erosion control plan is critical for protection of the wetland resources ' on the site. We encourage the developer to work closely with the Dakota County SWCD to develop an erosion control plan." ' R esponse: The draft AUAR identifies the areas of steep slopes and highly erodible soils on the ' Kelley Trust site. The Mitigation Plan includes measures to prevent or minimize erosion and sedimentation on the site, and indicates that the developer will implement the MPCA's Best Management Practices (BMP's) as the guidelines for urban erosion and ' sediment control on the site. The developer will work closely with the Cities and Dakota County SWCD to develop an erosion control plan for the site. ' 7. Page 2, Paragraph 2 "Item 18, Water Quality, Surface Water Runoff -- We encourage the city and the 1 developer to investigate using drought - resistant turf where possible, and to encourage use of phosphorus -free fertilizer to protect water quality." Response: We will add this statement to the Mitigation Plan for this item: "The Cities and the ' developer will investigate using drought- resistant turf where possible, and will encourage residents to use phosphorus -free fertilizer to protect water quality ". ' 8. Pane 2, Para , 2ralffi 3 "Item 30, Cumulative Impacts —While the AUAR is a tool for reviewing cumulative ' impacts of multiple projects in a defined area, it is no better than an EAW for evaluating cumulative effects of activities adjacent or outside the study area. The D1tiR recommends RGUs not limit cumulative effects analysis to the AUAR ' boundary. Response: Thank you for this informational comment. The Draft AUAR has analyzed effects of development activities outside the study area where applicable, for example traffic and ' noise impacts outside the study area, and storm water impacts where storm water will flow outside the study area (Birger Pared). Final AUAR — Kellcy Trust Property 7 J �I C Metropolitan Council Comments 1. Page 1, Paragraph 3 and 4 "The description of the project on page four says that there will be a total of 64.9 net acres of multiple - family housing at a density of 4.8 units per acre ... and 323.8 net acres of single - family "attached" units at a net density of 2.6 units per acre ... and an overall area of 465 net acres and an overall net density of 2.5 units per acre. The numbers do not add up. If the project proposes to build a total of 1,209 dwelling units on 465 net acres of land, the net density of the entire project is 2.6 units per net acre. The AUAR on page three says that there will be 360 multiple- family units of which 50 will be built in Apple Valley, If there are 64.9 net acres developed for 360 multiple - family units, the net density would be 5.5 units per acre. If there were 323.8 net acres developed for 849 single - family units, the net density would be 2.6 units per acre. These numbers total 1,209 units on 388.7 net acres, a net density of 3.1 units per acre. However this net acreage is different from the 465 net acres also mentioned on page four. If the net density of the entire project is 2.6 units per acre, this is less than the minimum three units per net acre urban density recommended by the Council." Response Density calculations The draft AUAR correctly states that there is a total of 1,209 units, broken down into 360 multiple family attached units and 849 single family detached lots. Page 3 of the text goes onto explain that 1,153 units will be located in the City of Rosemount, with the remaining 56 being located in the City of Apple Valley. Of these 56 units, the text states that 50 are to be townhouse units and 6 are to be single - family units. The information is all currently accurate. The density calculations that are provided on page 4 of the text, however, were not based on a total of 1,209 units, but rather by our error, only on 1,153 units within the Rosemount portion of the project, and the net acreage used by those units. The total number of units and density calculations should reflect t1he 1,209 total units. The Text on page 4 should therefore be updated to reflect the Apple Valley units and acreage, as follows: L J "The 360 multiple family attached units are proposed to be located in the southeastern and western portions of the AUAR area, comprising an approximate total of 100 acres of land, and containing a net density of 3.6 units per acre. The 849 single- family detached units would be located throughout the remainder of the site, comprising an approximate total of 329.8 acres, and a net density of 2.6 dwelling units per acre. The AUAR area is proposed to contain an overall net density of 2.8 units to the acre, based on a land area of 429.8 net acres."

The Mitigation Plan (Goal 4) states that "the developer will assure no net loss of these (wetland) resources by avoiding and minimizing wetland impacts when feasible, and mitigating for unavoidable impacts ... The developer shall follow the requirements of the City of Rosemount and City of Apple Valley Wetland Management Plans and applicable state and federal regulations to avoid, minimize, and /or mitigate for impacts to wetlands that result from development. The developer will work with the Cities, VRMWO, DNR, U.S. Army COE, and other permitting agencies to implement this goal. 4. Page 2, Paragrati 3 "Item 10: Cover Types —This section indicates that the size of impervious surface will increase from three to 147 acres. Of the total 580 -acre site, 25 percent will be impervious, 51 percent will be lawn, landscaping and parks, 17 percent will be brush /grassland and wooded /forest and seven percent will be wetland and watercourses. The impervious percentage will increase from less than one percent to over 25 percent. The developer should work with the two cities, the VRWMO, and the Dakota County Soil and Water Conservation District (SWCD) to design and construct the best erosion control and stormwater management practices for the project area. Storm water management practices may include things such as detention basins, infiltration basins, filter strips, rainwater gardens, and vegetated swales, while erosion control measures may include things such as hay bales, silt fence and check dams." Reslonse: Goals 5, 7, and 8 of the Mitigation Plan indicate that the developer is committed to working with the Dakota SWCD, VRWMO, and the two cities to minimize erosion and sedimentation and impacts on surface waters as the area is developed. The protection strategies detailed under these goals indicate that the developer will implement the MPCA's hest N.1anagement Practices as well as strategies such as detention basins, infiltration basins, filter strips, rainwater gardens, vegetated swales, and other practices identified in the Council's comments to meet the identified goal.

There are many areas on the site that have slopes greater than 12 percent. Most of the project area is classified as having soils that are highly erodible or potentially highly erodible. These two facts cause a significant amount of concern. The developer will need to make the extra effort to ensure that proper erosion control measures are in place before any dart is moved. It most likely will not be enough to use just the typical erosion control measures such as hay bales and silt fence at this site. The developer should work with the cities, the VRWMO, and the SWCD to determine the most effective best management practices to use at this site.

Pie 4. Paragraph 1 "Item 18: Water Quality - Surface Water Runoff—The AUAR discusses the need to lower the ordinary high water level (OIIWL) for Birger Pond. The city of Rosemount has worked with the DNR and VRWI''rIO to develop a management plan for this basin. Council staff is concerned about this basin and the increased runoff that will be discharged to the basin as development occurs. The developer should work very closely to monitor changes in the pond levels to make sure that the proposed solutions are actually working. The proposed pond outlet will discharge to Lakeville and ultimately to the Vermillion River. There is a flooding problem for the downstream communities along the Vermillion River. This makes it even more important that the proposed development and discharges to Birger Pond are carefully managed." Respon In the development of the outlet control for Birger Pond, the entire development area contributing to Birger Pond was examined and evaluated for fully developed conditions. This analysis included a fully developed Kelley Trust property at a density greater than what is currently proposed. Because the outlet out of Birger Pond is at a relatively slow rate, the Birger Pond ponding area will hold a 100 -year storm with no outlet. The City will continue to monitor ponding levels to make sure that the pond is operating within design parameters. While we agree that the ultimate pond outlet for this area will be through the City of Lakeville and to the Vermillion River, there are no plans at this time or for the immediate future to complete an outlet to Lakeville. At this time the runoff will be maintained within Shannon Pond located within the City of Rosemount. We do not anticipate any flooding problems for downstream communities at this time and the future outlet will be designed in a manner that will minimize downstream disturbances to the Vermillion River. 11.

Final AUAR — Kelley Trust Property 14 Communicat fro SWCD on Feb. _2 2000, following_ request for information on Co unty Gre P lan: "The information you are requesting is being gathered as part of the Dakota County LCMIt Project. Protecting Farmlands and Natural Areas. Preliminary assessments to focus efforts such as land cover mapping have identified the area south of Lebanon Hills as a potential corridor connection. Unfortunately, the land cover mapping has not been completed and the Dakota County Farmland and Natural Area protection plan has not been developed... With regards to the 300' corridor width, that is a suggested width based on the literature (Staufer and Best, 1980; Schaefer and Brown, 1992, and others)." Resp onse: There are several issues to address in this comment regarding a potential wildlife corridor on the site: Corridors in Dakota Coant Rosemount City staff have discussed wildlife corridor issues with staff from the Minnesota DNR Natural Heritage Program. The DNR has identified a corridor along the Mississippi River as the significant wildlife corridor within the city. No corridor has been identified by the DNR on or near the Kelley Trust Site. It is clear from the SWCD communication of February 2, 2000, that the County is in very preliminary stages of mapping farmlands and natural areas in. the County, and has identified the general area south of Lebanon Hills Park as a potential corridor. No specific information has been provided about the type (,recreational, habitat, or other type) or significance of this corridor, which species are significant for corridor planning in this area, or which areas within this general area south of Lebanon Hills Park offer the best corridor connections. ' No data or science -based analysis from natural resources agencies are available that identify a wildlife corridor within the Kelley Trust Property, or indicate the need for such a corridor. 0 Charac of wildlife habitat areas and corridors. The scientific literature in the field of Landscape Ecology suggests that a variety of kinds of wildlife habitat areas are important in the landscape. These include "patches" of protected habitat as well as "corridor" areas between them ( Landscape Ecology, Forman and Godron, 1986). "Corridors" are routes or conduits for movement. Many types of corridors have wildlife habitat value - -- including narrow strip corridors along hedgerows and fences, wider environmental resource corridors along streams and ridgetops, and planted corridors along shelterbelts and roadways. Each ty e of corridor has benefits for particular wildlife species. Strip corridors such as hedgerows have been found to be particularly significant for bird species, while wider corridors are needed for larger mammal species. Corridors with streams and interconnected water features are important to amphibians and many other species. Final AvAR — Kelley Trust Property 15 ' The scientific literature suggests that wide corridors, such as the 300' corridor suggested by the S\N'CD comment, usually follow natural landscape connections such as streams ' and ridgetops. Such corridors are natural movement areas for many species, and offer habitat elements (water, food, and cover) that make these corridors useful as habitat. (See literature review in Best Development Practices, Ewing, 1996, and discussion about corridor types in Forman and Godron). Options for wildlife corridors were reviewed as a part of the analysis completed for the Draft AUAK. No such wide, natural landscape corridor is available on the Kelley Trust Property site. No stream corridor is available on the site. A ridgeline exists to the north of the site, in the area occupied by larger -lot residential areas. This area may offer a ' significant habitat corridor, depending on the species of concern, and could be considered by Dakota County as it develops its corridor plan and implementation strategies. Habitat corridor identified on the Kelley T rust Site. A corridor that could facilitate animal movement from. north to south is visible within the site, and could be enhanced by plantings. This corridor connects wetlands and ponds at the north end of the site (near Shannon Parkway), along the east side of the elementary school property, to the ponds directly south. A "bird sanctuary" with appropriate plantings is planned for the senior housing area just south of the elementary school. The developer will work with the City ' to modify planting plans in this area to enhance its use as a corridor for wildlife movement within the site. The County may investigate options for continuation of the corridor outside the Kelley Trust Property, and work with private landowners in adjacent ' areas to protect any identified connecting areas. The Kelley Trust site and surrounding areas are already fragmented by existing ' developed areas and major roadways. Additional analysis by the County is needed to identify potential viable corridors and. species of concern in the area south of Lebanon Hills. species, or species of concern have been identified on the site. Protection of si2nifica wildlife habitat resources on the site. The high quality wildlife habitat areas remaining on the Kelley Trlast site are the oak woodlands in the north - central and northwest portions of the site, and the wetlands scattered through the central portion of the site. These are relatively large patches of diverse, high quality oak woodlands, and small, high quality wetlands. They are the only high quality natural areas remaining on the site, which has had most of its natural community areas heavily altered by agricultural uses. "Therefore, the site plan proposes protection and restoration of these communities, and establishment of line -type corridors among them to provide connections for the animal species using the site. The wildlife species currently using the site are species common to urban and agricultural areas.

The County's natural areas planning efforts should identify high - quality habitat patches, such as the woodlands on the Kelley Trust property, as well as potential wildlife travel corridors of a variety of types, to meet the needs of a variety of wildlife species. These may include significant natural corridors, such as the Vermillion River and Mississippi River, that offer good possibilities for the establishment of wide, protected corridors, as well as narrow "line" corridors along roadways and fence rows. These efforts should be based on identification of species of concern and their critical habitats (see discussion in Forman and Godron, as well as Landscape Linkages and Biodiversity, Hudson, 1991). When the County has completed its inventory and mapping of habitat and corridor areas, it should identify mechanisms for protection of these areas, such as the use of conservation easements, fee title purchase of significant properties, transfer of development rights, etc. A good model for this effort is the completed Greenway Plan for Washington County, Minnesota, which includes a variety of mechanisms for protection of the significant greenways for habitat and recreation that have been identified in the County. The County will then be able to work with private landowners to permanently protect significant habitat areas. In summar: T he Minnesota DNR and Dakota County's natural areas planning efforts ' have not identified a major wildlife movement corridor on the Kelley Trust property site. No significant natural corridor such as a stream or ridge line exists on the site. The site has been highly altered and fragmented by agricultural uses, surrounding residential ' development, and existing roadways. Wide corridor connections to habitat areas off-site are not readily apparent. ' The analysis completed for the AUAR identified the significant habitat patches remaining on the site, and potential corridors for wildlife movement among these areas. The developer and city will work together to increase the habitat value of a north -south corridor on the site, immediately east of the elementary school. The high quality habitat areas and this corridor connection is proposed for protection and restoration in the Mitigation Plan (Goals 4,5 and 6). As the County completes its corridor analysis and planning efforts, it may identify a significant wildlife movement corridor in the vicinity of the Kelley Trust site, or additional important habitat patches in the area and opportunities for line corridor connections to those on the Kelley Trust site. It should identify mechanisms for protection and enhancement of these areas, and work cooperatively with landowners to establish permanent protection of areas identified as significant in the county -wide plan. 3.

A substantial amount of imperviousness will be created and the impact of the increased runoff volumes on downstream waters and surficial groundwater tables must be determined. This level of assessment is warranted because, as state in State Code Chapter 4410.3610, Subp. 4 `the content and format of an AUAR must be similar to that of an EAW, but must provide for a level of analysis comparable to that of an EIS.

In the development of the outlet control for Birger Pond, the entire development area contributing to Birger Pond was examined and evaluated for fully developed conditions. This analysis included a fully developed Kelley Trust Property at a density greater than what is currently proposed for this site. Because the outlet out of Birger Pond is at a relatively slow rate, the Birger Pond ponding area will hold a 100 -year event storm with no outlet. The City will continue to monitor ponding levels to make sure that the pond is operating within design parameters. While we agree that the ultimate pond outlet for this area will be through the City of Lakewille and to the Vermillions River, there are no plans at this time or for the immediate future to complete an outlet to Lakeville. At this time the runoff will be maintained within Shannon Pond located within the City of Rosemount. We do not anticipate any flooding problems for downstream communities at this time and the future outlet will be designed in a manner that will minimize downstream disturbances to the Vermillion River.

We believe the Dakota County values to be viable. However, using the ITE trip rates, an additional 1,450 trips, spread over the project approach/departure routes, will not cause any problems with regard to roadway capacity. No additional mitigation would be required using the ITE trip rates for trips generated. u Final AUAR — Kelley Trust Property 22 v xilI :Iddv 1 J I Appendix B. Mitigation Plan — Rosemount Kelley Trust Property (Revised for Final AUAR) 1.0 Introduction This comprehensive environmental protection plan has been prepared as a part of the Alternative Urban Areawide Review (AUAR) process for the City of Rosemount — Kelley Trust Property. The proposed development area also includes a portion of the City of Apple Valley. This plan is intended to satisfy the AUAR rules that require preparation of a "mitigation plan" that specifies measures or procedures that will be used to protect the environment from potential impacts of development of the Kelley Trust Property. Finally, the plan specifies legal and financial measures and institutional arrangements that will assure that the mitigation measures recommended in the plan are implemented. The mitigation plan will be used by the Cities of Rosemount and Apple Valley to guide development of the Kelley Trust Property through the avoidance, minimization, and /or mitigation of environmental impacts. The plan is not intended to modify the regulatory agencies' responsibilities for implementing their respective regulatory programs, or to create additional regulatory requirements. This mitigation plan is not intended to deprive or divest any person of any use of property or right to which they are entitled by law. Finally, the AUAR and this mitigation plan may be silent as to environmental concerns or impacts that may arise later within the context of specific development proposals, and could not be anticipated during the AUAR process. This should not be construed as a bar to requests for and commitments by the City and the project proposers to compile new and /or additional environmental impact information and analysis. The Cities of Rosemount and Apple Valley recognize that the emphasis of the AUAR is to closely examine the environmental impacts of proposed development on the Kelley Trust Property, as described in the P.U.D. plan. In additional to environmental impacts, the Cities must consider other issues as the area develops, including land use, design issues, finances, economics and transportation concerns. The Cities must balance all of these concerns along with environmental impacts through specific plan development and design review process. The Mitigation Plan is proposed based on existing conditions and existing information at the time of its writing. If new information, conditions or mitigation methods develop after the approval of this plan, the Cities may convene representative members from the natural resources agencies and organizations on the Technical Committee to consider the new information and develop new recommendations to meet the goals identified in the Mitigation Plan. Finally, this AUAR specifically identifies and analyzes the environmental impacts of development within the Kelley Trust Property area. However, actions outside the area 7 are beyond the control of the Cities of Rosemount and Apple Valley, and may affect the natural resources that the Mitigation Plan protects or mitigates. The Cities are committed to try to coordinate protection of the natural resources with other agencies and organizations as listed in the Mitigation Plan. The goals and strategies included in this plan were developed with the assistance of a Technical Advisory Committee for the AUAR process. The assistance of these individuals and their organizations is gratefully acknowledged. Participants in the Technical Committee meetings included the following: Pat Lynch, Minnesota DNR Waters Larry Westerberg, Minnesota DNR Forestry Jay Riggs, Dakota SWCD Tom Burt, Dakota County Highway Dept. Scott Peters, Minnesota DOT Eric Kilberg, MPCA Water Quality Division Judy Sventek, Metropolitan Council Patrick Peters, Metropolitan Council Rick Pearson, City of Rosemount Planning Dept, Bud Osmundson, City of Rosemount Public Works Dept.

City Wetland Management Plans have identified the functions and values of local wetlands, and specified specific strategies for protection and mitigation of losses to wetlands and their associated buffers. These communities and their quality rankings are identified on Figure 10 -2 and discussed in detail in the AUAR analysis. The goals and strategies that follow are proposed to maintain and /or restore the quality of the high quality natural communities that remain on the property as development occurs in the future. Goal 1: Protect and restore the two high quality woodland areas that remain on the Kelley Trust Property. These include the oak savanna identified in the west central portion of the property, and higher - quality portions of the large oak woodland in the northeast portion of the site. Protection Strategies: 1. Protect these areas with conservation easements or protective covenants that prohibit development, and allow only passive recreational use of these areas. ' 2. Develop and implement management plans that restore the quality of the native communities on these sites. Responsible parties: Private developer and homeowner's association Regulatory program: N/A ' Implementation timeframe: Conservation easements /protective covenants should be completed as development occurs. The restoration and management plan should be implemented by the homeowner's association. Goal 2: Protect healthy individual trees and groves of trees where possible, and mitigate for any loss of trees through replanting. ' Protection Strategies: ' 1. Complete a tree preservation plan as required in the Cities' Tree Preservation Ordinances. As a part of this plan, identify individual trees and groves of trees for protection. 2. Replace trees that are lost to development based on the requirements of the Cities' Tree Preservation Ordinances. r Responsible parties: Private developer Regulatory program: City Tree Preservation Ordinances Implementation time frame: Tree preservation plans should be developed along with grading plans for the development. Protection and replacement should occur as the development plan is implemented. Goal 3: Utilize trees that are removed during development rather than burning or disposing them as waste. Protection Strategies: 1. Work with the Minnesota DNR, Dakota SWCD, and other appropriate agencies to identify ways in which the trees removed during development may be put to positive use. (For example, trees and root balls may be used as a part of local stream restoration activities). Responsible parties: Private Developer, Minnesota DNR, Dakota DWCD Regulatory program: N/A 3 L Implementation time frame: Contact agencies before tree removal begins. Dispose of trees as portions of the project area are cleared for development. Goal 4: Protect wetland resources in the project area to assure no net loss of these resources by avoiding and minimizing wetland impacts when feasible, and mitigating for unavoidable impacts. Protection Strategies: Follow the requirements of the City of Rosemount's Comprehensive Wetland Management Plan and Apple Valley Wetland Plan and applicable state and federal regulations to avoid, minimize and /or mitigate for impacts to wetlands that result from development. ' The Cities shall allow "averaging" of buffer widths: the total area of buffer required by the ordinances shall be required, but the width of the buffer may be narrower in some areas (to accommodate road development, for example) if it is ' increased in other areas of the same wetland to meet the total area required over the entire wetland. ' Responsible parties: Private developer, City of Rosemount (enforcement) Regulatory program: Rosemount and Apple Valley Comprehensive Wetland Management Plans, Shoreland and Floodplain Ordinances, Minnesota Wetland ' Conservation Act, Sections 401 and 404 of the Clean Water Act, and Minnesota DNR Protected Waters Program. Implementation time frame: Complete analysis of wetland impacts and ' mitigation needs as final plat and grading plan are completed.

' 5.0 Surface Water Quality Goal 8: Protect and maintain the quality of surface waters (lakes and wetlands) in the Kelley Trust Property. City Wetland Management Plans have identified the quality of wetlands within the Kelley Trust Property, and noted that a number of high quality wetlands remain within the site. One large water body, Birger Pond, exists within the site, and has experienced elevated water levels during the past 8 to 10 years due to increased development in its watershed area. The Apple Valley and Rosemount Surface Water Management Plans include goals, policies and strategies for the protection of surface waters as development occurs within these cities. The Cities have worked with staff of the Natural Resource agencies to develop a management plan for Birger Pond, Proleclion Strategies: 1. Implement the MPCA's Best Management Practices as the guidelines for erosion and sediment control. 2. Implement the goals, policies, and strategies included in the Apple Valley and Rosemount Surface Water Management Plans to protect water quality. Use bioretention methods where applicable to store and infiltrate storm water and minimize runoff. These methods include maintaining native vegetation areas, ' creating dry and wet swales, infiltration basins, sand filters, and related methods. 4. Reduce impervious surfaces where possible to reduce storm water runoff volumes. ' S. Use skimmers or other outlet controls, NURP basins as a minimum, and siltation basins on ponds located upstream of priority waterbodies and wetlands. 6. Limit phosphorous levels from development areas to natural concentrations ' through proper sizing and design of ponds to provide for a minimum of 60 percent phosphorous removal. 7. implement the goals and policies of the Cities' wetland management plans to ' protect the quality of wetlands in the development area. 8. Implement the management plan for Birger Pond developed by the City of Rosemount and Natural Resource agencies. ' 9. Encourage residents to use phosphorus -free fertilizer to protect water quality. Responsible parties: Private developer, City of Rosemount, City of Apple ' Valley, Dakota SWCD, natural resource agencies Regulatory program: City Surface Water Management Plans, Wetland Plans, City Zoning and Subdivision Ordinances. ' Implementation timeframe: Identify strategies to implement these plans as a part of the final plat and grading plan; implement strategies as development occurs. ' 6.0 Traffic Urban development on the Kelley Trust Property site will impact a traffic, noise and air ' quality. The AUAR analysis indicated that the road network of the area has been planned and sized to accommodate the proposed development, and that noise and air quality impacts are within accepted standards. The Cities of Rosemount and Apple Valley will seek to minimize impacts in these areas as appropriate to protect the health, welfare and safety of the public. ' Goal Manage automobile traffic to safely accommodate development planned for the Kelley Trust Property. ' Protection Strategies: 1. Design and construct local roads to mitigate traffic impacts while meeting natural ' resource protection goals and strategies included in this Plan. Responsible parties: Private developer, Cities of Rosemount and Apple Valley, ' Dakota County, Minnesota Department of Transportation ' Regulatory program: City and County Comprehensive Plans, and agency regulatory programs.

Responsible parties: Cities of Rosemount and Apple Valley and Dakota County ' Highway Department Regulatory program: City Subdivision Ordinances Implementation timeframe: Implement existing regulations as development ' occurs. ' 7.0 Scenic Views and Vistas The City of Rosemount and residents in the area have noted that scenic views and vistas exist in the Kelley Trust Property area. Those identified include the following: 1) views from Shannon Parkway looking to the north from the existing development south of the Kelley Trust Property; 2) views from the highest land on the site looking toward Birger Pond, and 3) views from the homes to the north of the site looking toward the south. Development as proposed in the Kelley Trust P.U.D. will change these views. Strategies recommended to minimize or mitigate for these changes include the following: Goal 10. Preserve scenic vistas or use plantings to restore vistas and screen development along key view corridors. Protection Strategies: 0 1. Preserve individual trees or groups of trees, particularly along Shannon Parkway ' and along the northern boundary of the Kelley Trust Property, and require replanting based on the City's Tree Preservation Ordinance to protect and restore scenic views from Shannon Parkway and existing residential areas to the north. ' Responsible parties: Private developer, City of Rosemount Regulatory program: City Tree Preservation Ordinance ' Implementation time frame: Develop a tree inventory and plan as a part of the final plat and grading plan to identify trees and groups of trees to be saved. Create and implement a planting plan that focuses on restoration of a scenic ' corridor and screening for properties surrounding the proposed development. 2. Preserve the oak savanna area in the west- central portion of the site and its ' connections to Birger Pond to protect views in this area. Responsible parties: Private developer, City of Rosemount ' Regulatory program: N/A Implementation time frame: Develop strategies for protection of the oak savanna (conservation easement, protective covenant, etc.) as the final plat is ' completed for the development. implement these with the City or homeowners association as the development is implemented. 10 t ADOPTED ENVIRONMENTAL PROTECTION PLANS AND REGULATIONS The Cities of Rosemount and Apple Valley have a variety of plans, ordinances and regulations in place that address environmental issues in the proposed development area. These mechanisms will be enforced and amended as indicated in the Mitigation Plan to provide a comprehensive framework and set of tols to protect the natural resources of the area as development occurs: City Comprehensive Plans Zoning and Subdivision Ordinances Grading Permits Ordinances Stonnwater Management Plans and Ordinances Floodway Ordinances Wetland Management Plans Tree Preservation Ordinances Shoreland Management Ordinances Wetland Conservation Act Water Supply and Distribution Plans Comprehensive Park Plans 1 I 3 q 9 4` i -2 a a �w 5 � G r G � F '^ 6 9 ;< c c N < I u _ 0 0 3 3 fl -- ?l T T O O Y 0 G G � � omsmoNn , 0 0 3 A t1 ° d uao 0 o n0P� y Z� p a G i G m I D 1 I 1 I i I I o �n m c � p ur �' Y 1111 � < f • 1,��_ p rf < I I - - -- � I I F I I Rosemount Kelley Trust Property AUAR December 14, 1999 b. Are there any state - listed endangered, threatened, or special- concern species; rare plant communities: colonial tivaterbird nesting colonies; native prairie or ' other rare habitats; or other sensitive ecological resources on or near the site? X Yes No I Fish Resources No known fishery or fish habitat resources will be affected by the proposed development. The Minnesota DNR indicated that in the past it has considered using Birger Pond for game fish rearing, and would consider it again if the opportunity arose. After ' development, local angling demand might develop for angling on the property. Providing this opportunity may not be physically possible or ecologically sound. Wildlife Resources Wildlife habitat value is dependent on the composition, quality and connectivity of ' natural communities including woodlands, wetlands and grasslands. The highest quality natural communities remaining in the Kelley Trust Property are the higher quality woodlands and wetlands described in the preceding section on Land Cover Types. Much of the remaining land cover of the Kelley Trust Property has been altered in the past by farming and grazing. Measures that protect the diversity of these remaining high quality habitats are emphasized in the Mitigation Plan. MITIGATIVE MEASURES FOR WILDLIFE RESOURCES: ' Wildlife habitat value is dependent on the composition quality and connectivity of plant communities, such as woodlands and wetlands. Therefore, implementation of the strategies identified under Mitigation Measures for Natural Communities above, will also serve to protect wildlife habitat on the Kelley Trust Property as development occurs. Goal: Protect the remaining high quality habitat areas on the Kelley Trust property site as the area develops. Identify potential wildlife and recreation corridors and open space areas. Include natural community areas in these public open space areas, and use corridors to connect natural communities and protected open spaces. Protection and Mitigation Strategies: 1. The developer and Cities shall implement the strategies identified under p p g ' Mitigation Measures for Natural Communities to protect the high quality wetland and upland resources and wildlife habitat that exist on the site. 2. The developer and city shall implement city park and trail plans, designing parks and trails to protect and connect natural communities and habitat areas. 17 a I Rosemount Kelley Trust Property AUAR _^ December 14, 1999 Will the project involve the physical or hydrologic alteration (dredging, filling, stream diversion, outfall structure, diking, impoundment) of any surface water (lake, pond wetland, stream, drainage ditch)? X Yes No ' If yes, identify the water resource to be affected and describe: the alteration, including the construction process; volumes of dredged or fill material; area affected; length of stream diversion; water surface area affected; timing and extent of fluctuations in water surface elevations; spoil disposal sites; and proposed mitigation to minimize impacts. It is anticipated that construction of residential units and utilities on the site will impact some of the wetlands on the site and their buffer areas. Final site plans and grading plans will identify the wetlands that will be affected and degree of impact. The City has a Protected Waters permit pending for a pumped outlet from Birger Pond. The DNR expects to be able to issue the permit shortly. MITIGATION MEASURES FOR IMPACTS ON WATER RESOURCES (WETLANDS) The mitigation plan includes strategies to protect wetlands within the proposed development area, and mitigate for losses resulting from development activities on ' the site: Goal: Protect wetland resources in the project area to assure no net loss of these ' resources by avoiding and minimizing wetland impacts when feasible, and mitigating for unavoidable impacts. ' Protection and Mitigation Strategies: 1. The developer shall follow the requirements of the City of Rosemount and City of Apple Valley Wetland Management Plans and applicable state and federal regulations to avoid, minimize and /or mitigate for impacts to wetlands that result from development. The Cities shall allow "averaging" of buffer widths on some wetlands where this will not compromise wetland and buffer function. ( "Averaging" means that buffer widths may be reduced on one portion of a wetland, but would be enlarged on another portion of the same wetland buffer, so that the overall buffer size remains the same.) 2. Site plans will indicate methods that will be used to avoid impacts to wetlands and ' meet the requirements of the City's Wetland Management Plan. Buffers around wetlands will be clearly delineated with corner markers or monuments at lot corners to make them visible and to aid enforcement of the buffer requirements.

Yes X No If yes, indicate the current and projected watercraft usage and discuss any potential overcrowding or conflicts with other users or fish and wildlife resources. This item need only be addressed if the A UAR area would include or adjoin recreational water bodies. 16. Soils a. Approximate depth (in feet) to Groundwater: minimum 0 average 100 Bedrock.. minimum l0 t._ average 200 tt. b. Describe the soils on the site, giving SCS classification, if known. (SCS ' interpretations and soil boring logs need not be attached.) A standard soils map covering the area should be included. ' Figure 16 -1 indicates the soils on the site. The geologic atlas indicated that the site is mainly covered by surficial deposits of till, which is composed of reddish -brown sandy loam. Stringers of sand and gravel may be present within this till, but generally this ' material is not highly permeable and does not allow high infiltration rates. The extreme eastern edge of the project area is covered with deposits of outwash, which consists mainly of sand and gravel. These materials generally allow much higher infiltration rates than till, but this area comprises less than 20% of the overall project area. ' The majority of the soil types indicated by the Dakota County Soil Survey to be present in the study area exhibit moderate infiltration rates. In general, the majority of soils are silty loams mixed with sandy loams. Silty loams have low -to- moderate infiltrate rates ' while sandy loams have moderate -to -high infiltration rates. No soils in the project area appear to have an excessively high infiltration capacity. ' 17. Erosion and Sedimentation a.

The developer will use skimmers or other outlet controls, NURP basins as a minimum, and siltation basins on ponds located upstream of priority waterbodies and wetlands to protect water quality. 6. The developer will limit phosphorous levels from development areas to natural concentrations through proper sizing and design of ponds to provide for a minimum of 60 percent phosphorous removal. 7. The developer will implement the goals and policies of the Cities' wetland management plans to protect the water quality of wetlands in the development area. 8. The City of Rosemount will implement the management plan for Birger Pond developed with the Minnesota DNR. 9. The City and the developer will encourage residents to use phosphorus -free fertilizer to protect water quality. 19. Water Quality— Wastewaters a. Describe sources, quantities, and composition (except for normal domestic sewage) of all sanitary and industrial wastewaters produced or treated at the site. Normal domestic sewage is the only type of wastewater expected from the uses in the annexation area. The quantities and handling of the wastewater are presented in the Cities' Sanitary Sewer System Plans and are proposed to be fully implemented in the study area. b. Describe any waste treatment methods to be used and give estimates of composition after treatment, or if the project involves on -site sewage systems, discuss the suitability of the site conditions for such systems. Identify receiving waters (including ground water) and estimate the impact of the discharge on the quality of the receiving waters. (If discharge may affect a lake consult "EAW Guidelines" about whether a nutrient budget analysis is needed.) All proposed residential units will be connected with the Cities' sanitary sewer systems. These sanitary sewer facilities are connected to and treated at a Metropolitan regional facility, the Rosemount treatment plant. Capacity at the plant is adequate to serve the proposed development. C. If wastes will be discharged into a sewer system or pretreatment system, identify the system and discuss the ability of the system to accept the volume and composition of the wastes. Identify any improvements, which will be necessary. The quantities and handling of the wastewater are discussed in the City's sanitary sewer system plan. The Cities' trunk facilities are sized to handle the increase in sewage from the Kelley Trust Property P.U.D. The Metropolitan treatment facility has sufficient capacity to receive this additional flow as outlined in the Cities' Comprehensive Plans. i `ddvssaoau si `saIno.i sa.ti1vuddyn fo szsTlvuv uv 2ulpnlour dllvdaua2 `mama.l fo laaal aArsuaju? allow v `papnlou7 aq o) adv (Cagj f! `sm inuv UVOV aq) ui uo.zsnlout lvuortdo uv a.�v va.�v YVI) y un ssodo pinom r vgj s, fo saddi , Iv!daljv,, a roy47 WMV uv_fb Jdvd v aq of pajoadxa d1lowiou aav vary yVflV uv u as zgj!m sn puvl 2uzuzofpv aq1 xtdas of fl!.ivtu papua;ut s (�ola `tam fs .rajvatu�.Iojs `da)vna `s.saa-tas `spvo.$) juawdolaaap aqj aet tas o) pauuvld a,tMlondlsv4uj •q •xtpuoddd aul ui popnioui si CIfld otp jo Iat,d u sv Xuadoad 1sni L XolloN aul ioj pasodoad svon cords uado pur �lat,d jo Isil v - cords uado aatpo jo saaou £'9L Pin `spuod put spurpam jo saaor O£ `puns hard lruotltppr Jo saaot, OZ `purl 31ard polt,oipop -aid jo saaor OZ Xlalruxixoaddr fuipnloui `aot,ds uado st, ureuzaa of posodoad st roar - dVfIV au1 jo Iuooaod £Z Xlalt,tutxoaddV - aouds uado puu spuod `spuuliam `sxard sr poluuBisap sroat, sopnloui asn purl aot,dS uado put, sVed posodoad Oqi aavdS uado pug "agd •XallrA olddV jo ,�IID put, lunouzaso -d j0,Clt3 a tp Jo surld antsuatlaadtuoo OZOZ oql tptm Iualsisuoo can CIfld Isnil Xalla?I oql ui pasodoad satlisuop put sasn purl atll - uaat, oql ui spuullom pug sodols dock otll 01 aouaaagap ui alts atll jo suaau Isom put, tptou aoj posodoad si luatudolanap Xltsuap mo-1 •t,aat, situ aoj posodoad on shun oul jo luooaad 08 Xlalrtuixoaddd -spu maj st,tl our l73l3 ,(lantlrlaa si uoium `alis atil jo puo Isro atjl aoj posodoad on t,aar -dVfIV oql ui so pisuop isog5lq 3qj •saaor IOU 8'6Ztb Jo t,a purl r uo posrq `acct atp o shun 8'Z jo Xiisuap IOU llt,aano ut, utt,luoo of posodoid si - Pact, dVfl 1 oql •aaot, cad shun iluillomp 9•Z jo Slisuop lau u puu `saaar 8'6Z£ 30 lt P Buisudwoo `alts aul jo aapuirtuaa atp Inog5tioxgi polrool oq pinom shun patlouIIV XIiure,4 alOuiS 6b8 aqI - aaot, and shun ouillamp 9'£ jo ,�lisuop lau t, 2ututrluoo put `purl Jo scoot, 001 jo Irlol r 2uisiadtuoo `root, -dVfIV a ul jo suojlaod uaa d puu uaalsuatpnos a ul ui pa lu ool oq of posodoad oar shun patlouuV X[lu- m3 -illnW ;)ql - Iriluapisa-d XIisuoQ morl pauoz aq o1 posodoad gloq oar souioH Sliumd a1 put' satu011zm01 atp `XaiiuA olddV ul •lrtluapisag XlisuaQ tunipaW—£ --d pauoz oq o1 posodoad aau shun 2uisnolg aoivaS our sauzoH tlat auI `Z -mod pauoz oq of oslu satuotlumOl our sauzoH um L sopnlout asn purl It,iluopisaa pogovuV = Sliujr3 - illnW au.L 'lriluapisa-d XIjsuaQ olraapoW - - Z - 21 si srlliA 0 l ,{ Isa3i'I Put satuoH OSM10D au1 put, `.loialsiQ Iriluapisa� �lisuaQ mo�l -- l -� si satuoH lruoiltpr zI put `papaig tuoisno oissvID `urgangnS oissulo all "IaialsiQ Iriluapisag XjjU.Irj 3l2uiS nlisuaQ m0I XaaA - -7g si sauzoH alulsg oqj jo i3uiuoz posodoad atll `lunowoso - d ul 6661 `61.raqu+a"(7 YM v da o- rd;.rn.1,L , a1laN 1uno:uasoy F n 1 1 Rosemount Kelley Trust Property AUAR December 14, 1999 8.

Figure 5 -3, PUD Concept flan, does not illustrate units located on. the: Apple Valley portion cf the sits. Item 6, Description - The project description describes housing densities after construction. What would be the ovcTall housing density with wetland areas deducted? Item 11. Fisheries Resources - In the past, the 5 INR has considered using Birger Pond for gamefish rearing, and would consider it again if the opportunity arose. After development, local anglkig demand might develop for angling or, the property. Providing this opportunity may not be physically possible or ecologically sound Item 12, Phy3ical impacts on Water Resources - T11e. AUAR states that "Final site plans and grading plans w ill idenaify the wetlands that will be affected and degree of impacr." Plans should also indicate how impacts will be avoided or mai ntai n ed below levels established in Lhe City's `Vetland Management Plan. We recommend that buffers around wetlands be clearly delineated and marked with corner markers or ,nonutnents at lot corners to make there visible and to aid enforcement of the buffer requimments. The City has a protected Waters permit pending for a pumped outlet from Birgar pond. The DNTR expects to be able to issue the permit shortly.

Council staff has conducted a review of tre Kelley Tnist Property AUAR to determine its adequacy and accuracy in addressing regional concerns. The staff review has concluded that the AL is complete and accurate with respect to regional concerns and raises no major issues of consistency with Council policies. however, staff provides the following technical comments for your consideration: The proposed development project involves the construction of 1,209 dwelling units, including 360 multiple- family attached units and 849 single - family detached lots on 585 gross acres of land. Fifty acres of the project area are within the city of Apple Valley. Item 6 — Description ' The description of the project on page four says that there will be a total of 64.9 net acres of multiple - family housing at a density of 4.8 units.per acre, .,and 323.8 net acres of single-family - "attached" unita -at.a -net density of 2.6 units per acre.. _and an overall area of 465 net acres. and a overall net density of 2.5 units per acre. The numbers do not add up. ' If the project proposes to build a total of 1,209 dwelling units on 465 net acres of land, the net density of the entire project is 2.6 units per net acre. The AUAR on page three says that there will be 360 multiple - family units of which 50 will be. built in Apple Valley. If there are 64.9 net ' acres developed for 360 multiple- family units, the net density would be 5.5 iuiits per acre. If there were 323.8 net acres developed for 849 single - family unhs, the net density would be 2.6 units per acre. These numbers total 1,209 units on 388.7 net acres, a net density of 3.1 units per acre. however, this net acreage is different from the 465 net acres also mentioned on page four. If the net density of the entire project is 2.6 units per acre, this is less than the minimum three units per net acre urban density recommended by the Council.

Tier H sewer plans are required elements of ' community comprehensive plan updates. Comprehensive plan updates need to be submitted to the Council for review for all communities that plan to alter, expand, or improve their sewage disposal system. The cities of Apple Valley and Rosemount will ' need to have approved Tier 1I Sewer Plans before any additions ar alterations can be initiated for the proposed development. The AUAR states that the city is the Local Governmental Unit (LGU) for the Wetland Conservation Act. As both Rosemount and .fipple Valley are involved in permitting the project, each is probably the LGU under the Wetland Conservation Act for their ' respective proposed development areas. Ir. any case, the developer should work with the cities, the Vermillion River Watershed Management Organization (VRWMO), the Department of Natural Resources (MR), and possibly the U.S. Army Corps of ' Engineers (COE) to assure the intent of the Wetland Conservation Act is upheld. All wetland loss should be avoided if possible. Where wetland loss is unavoidable, proper mitigation is required. ' Itenz 10 — Cover Types ' This section indicates that the size of impervious surface will increase from three to 147 acres. Of the total 580 -acre site, 25 percent will be impervious, 51 percent will be lawn, landscaping and parks, ? 7 percent will be brush/grassland and wooded/forest and seven ' percent will be wetland and watercourses. The impervious percentage will increase from less than one percent to over 25 percent. The developer should work with the two cities, the VRWMO, and the Dakota County Soil and Water Conservation District (SWCD) to ' — design and construct the- best.erosion control and stormwater management practices for the project area. Stormwater management practices may include things such as detention basins, infiltration basins, filter strips, rainwater gardens, and vegetated swales while erosion control measures may include things such as hay bales, silt fence and check. dams. The AUAR does a good job of evaluating the woodland areas and identifying which areas are the high, low and moderate protection areas. The developer should continue to work with the cities to determine the actions needed to protect the high priority protection areas. The developer should work with the communities, the SWCD, and the DNR to determine the appropriate mitigation measures for woodlands lost during development. The city of Rosemount has completed a wetland function and value assessment. The ' developer should continue to work with the two cornrnunities, the SWCD, the VRWMO, P.03/05 FEB -01 -2000 13:43 Richard Pearson January 26, 2000 Page 3 CITY OF ROSEMOUNT 6514235203 P.04i05 and the DNR to assure high priority wetlands are protected and impacts to lower priority wetlands are properiy mitigated. Item 11— Fish, Wildlife, and Sensitive Resources The DNR Natural Heritage Program database indicated that there were three known occurrences of Blanding's turtles, a state threatened speries, in tha vicinity of the project. To minimize impacts on the turtles, the developer should work with the DNR to develop a management program. Typically, we would recommend that at a minimum, workers be informed of the preserice of Biandiitg's turtles in the area. Item 12 — Physical Impacts an Water Resources ' It is anticipated that future development of the site will impact some of the on -site wetlands and their buffer areas. Final site plats and grading plans will identify thc: wetlands that will be affected and the degree of impact. The developer should agree to ' work with the cities, the DNR, the VRWMO, and the SWCD to find the best solutions to wetland impacts. Since the citywide assessment of wetland function and value has been made, the expectation of Council staff is that wetlands identified for preservation should ' be avoided entirely. By approving this AUAR, we are assuming that this issue is not closed. We reserve the right to question wetland impacts and mitigation discussions that may arise in the future through our review of DNR protected waters and COE permits. ' Item 17 —Erosion and Sedimentation ' The AUAR indicates that over 800,000 cubic yards of soil will be moved and graded for the proposed project. There are many areas on the site that have slopes greater than 12 percent. Most of the project area is classified as having soils that are highly erodible or ' potentially highlyerodible, These two facts cause a significant amount of concern. The developer will need to make the extra effort to ensure that proper erosion control measures are in place before any dirt is moved. It most likely will not be enough to use just the typical erosion control measures such as hay bales and silt fence at this site. The developer should work with the cities, the 'VRWMO, and the SWCD to determine the most effective best management practices to use at this site. The developer should obtain a National Pollutant Discharge Elimination System (NPDES) constructionn permit for this site. Erosion and sedimentation control practices ' must comply with the Minnesota Pollution Control .Agency's urban "best management practices," titled Protecting Water Quality in Urban Areas or an equivalent set of standards for erosion control. The developer will need to work with the appropriate ' regulatory agencies to prepare a suitable erosion control management plan for this site.

Item 18 - Water Quality - Surface Water Runoff The AUAR discusses the need to lower the ordinary high water level (OHWL) for Binger Pond. The city of Rosemount has worked with the DNR and the VRWM0 to develop a management plan for this basin. Council staff is concerned about this basin and the increased runoff that will be discharged to the basin as development occurs. The developer should work very closely to monitor changes in the pond levels to make sure that the proposed solutions are actually working. The proposed pond outlet will discharge to Lakeville and ultimately to the Vermillion River. There is a flooding problem for the downstream communities along the Vermillion River. This makes it even more important that the proposed development and discharges to Birger Pond are carefully managed. The AUAR also states that ponds are proposed as part of the project. To be consistent with the Council's Interim Strategy for Nonpoint Source Pollution and to maximize pollutant removal efficiencies, all wet detention ponds should be designed according to NI URP or similar criteria for wet detention basins. ' This will conclude the Council's review of the AUAR. The Council will take no formal action on the ALTAR.

The proposed project entails 1,209 multi- and single - family units on approximately 535 acres. The SWCD's review revolves around four primary topics: soil erosion and sedimentation control, stormwater, greenways, and wildlife habitat. The Kelly Trust Property contains a unique mixture of «woodlands,, wetlands, and rolling topography. The site is also positioned near other high quality natural areas, further increasing its local and regional significance. Accordingly, the level of effort to protect the site's natural, resources should reflect the site's unique natural features and its importance as a greenway connection. Our cpmments and suggestions reflect this position and are respectfully submitted for your review and consideration: Note: Goat numbers are referenced from Appendix B of the document. ' Item 10: Cover Types: Mitigative Measures for Natural Communities Goal 5: Protect and Maintain the quality of surface water flows to wetlands Identify and protect infiltration areas on the site. Determine which wetlands are hydrologically ' maintained by surficial groundwater and where the infiltration areas for this surficial groundwater originates. Protect these areas from development or mitigate the impacts by strategically locating infiltration BMPs. ' Item 11: Fish, Wildlife, and Sensitive Resources Goal 6: Protect the remaining high quality habitat areas ... ' The SWCD commends these efforts. To clarify the third strategy listed under this goal define (1) corridor and (2) the developer's acceptance of effective greenway /wildlife corridor development. ' Specifically, where would 300 foot -wide, naturally vegetated comdor fit on the proposed site plan? It appears the proposed greenways may provide recreational opportunities (eg trails) but would not. create a viable multi- species wildlife corridor. Based on preliminary assessments conducted as part of a LCMR project currently underway in Dakota County, the site. is an important link between the ' undeveloped areas east of Hwy 3 and Lebanon Hills and may also be an important link in a potential greenway connecting the North Branch of the Vermillion River to Lebanon Hills (via Long and Farquar Lakes). 1 I AN EQUAL OPPORTUNITY EMPLOYER ' Kelly Property ALTAR 2 Dakota SWCD Comments Item 12: Physical Impacts on Water Resources ' The SWCD anticipates working very closely with the Developer and Cities once a V4'CA Wetland Replacement Plan is submitted to ensure full sequencing is followed and that wetland impacts are avoided and minimized to the extent possible. Based on preliminary discussions, the SWCD assumes ' only minimal amounts of wetland impacts are anticipated. Goal 8: Protect and maintain the quality of surface water flows to wetlands. ' Define the BMPs the developer will consider to use on this site to "Protect and maintain the quality of surface water flows to wetlands." Traditional BMPs alone may not be adequate to effectively protect ' the site's resources. Silt fence at the toe of graded slopes does not suffice. Comprehensive management of the site's stormwater runoff, in conjunction with BMPs to address runoff rate and volume, is needed. See:comments below regarding erosion and sedimentation. Item 13: Water Use Clarify if temporary dewatering for construction activities will be needed. If temporary dewatering is needed, clearly define the BMPs that will be used to treat the discharge of the dewatering pumps. Item 17: Erosion and Sedimentation The soils and slopes on the site create conditions very susceptible to erosion. Proper BMP selection, installation, and maintenance is critical on this site. Goal 7: Minimize erosion and sedimentation ... ' Construction phasing will play a central role in minimizing erosion on this site. The site should not be mass graded. Further, grading plans should be developed to (1) follow the contours of the site, thereby minimizing the need for mass soil transfers, and (2) minimize the amount of disturbed land ' that will be exposed at one time. The SWCD requests the opportunity to review and continent on preliminary grading plans as they are submitted to Rosemount and Apple Valley. Item 18: Water Quality — Surface Water Runoff ' As stated in the A.UAR, the site is currently isolated and the long -term proposal is to pump water from the site across a watershed divide and into the North Creek of the Vermillion River subwatershed. Areas along North Creek and the Vermillion River are experiencing increased flooding and downstream ' stormwater impacts should be quantified. A substantial amount of imperviousness will be created and the impact of the increased runoff volumes on downstream waters and surficial groundwater tables must be determined. This level of assessment is warranted because, as stated in State Code Chapter 4410.3610, ' Subp. 4 "the content and format [of an AUAR] must be similar to that of an EAW, but must provide for a level of analysis comparable to that of an EIS . . ." ' Goal 8: Protect and Maintain the quality of surface waters ... The SWCD commends the strategy to use bioretention methods to store and infiltrate [and evapotranspirate — a very important component that should not be overlooked] stormwater and ' Kelly Property AUAR Dakota SWCD Comments minimize runoff. Please clarify the extent these innovative BMPs will be utilized. We suggest undertaking a thorough assessment of the site's runoff and determining specifically what BMPs will minimize the post - development curve number (to reduce runoff volume) and maximize the time of ' concentration (to reduce peak discharge rates) on the site. Strategically applying these concepts is called the Low Impact Development (LID) approach. ' The LID approach includes minimizing impervious areas and maximizing on -site water storage and use. Example LID BMPs include road width reductions, shared driveways, grassed waterways in place of storm sewers, recessed parking lot islands, and many others. Refer to the following ' resources for more information about the LID approach: Better Site Design: A Handbook for Changing Development Rules in Your Community, Center for ' Watershed Protection, 1998. Conservation Design-for Stormwater Management, Delaware DNR, 1997, Low - Impact Design Manual, Prince George's County Government Department of Environmental Resources, Maryland, 1997. ' The Dakota SWCD may be able to provide financial incentives to sLipUort incorporation of LID concepts into the devel9pment v lans. Please contact our office for more information. Appendix B. Mitigation Plan ' 3.0 Wildlife and Sensitive Resources Goal 6, Protection Strategy 2, Implementation Timeframe: Parks and trail areas should be ' identified and reviewed with stakeholders long before the final plats are submitted to the cities. These areas must be proposed and reviewed prior to preliminary plat review. Goal 6, Protection Strategy 4, Implementation Timeframe: Habitat protection areas should be ' identified and reviewed with stakeholders long before the final plats are submitted to the cities. These areas must be proposed and reviewed rp for to preliminary plat review. 4.0 Erosion and Sedimentation Goal 7, Protection Strategies 1 -5: Please submit the proposed grading and erosion control plans to ' the Dakota SWCD for review and comment prior to preliminary plat approval. Define the amount of the security for performance of obligations regarding erosion and sedimentation ' control — for a site such as this, $2,000 to 3 /acre is suggested. 5.0 Surface Water Quality Goal 8, Protection Strategies 1 -8, Implementation Timeframe: Identify strategies to implement these plans prior to preliminary plat approval. The incorporation of bioretention, infiltration, and other LID BMPs requires that stonnwater management be an equally important design consideration 1 as road alignments and lot configurations.
