The Best Management Practices (BMPs) identified in the SWPPP and in this permit must be installed in an appropriate and functional manner. B. EROSION PREVENTION PRACTICES 1. The Permfttce(s) must plan fur and implement appropriate construction phasing, vegetative buffer strips, horizontal slope grading, and other construction practices that minimize erosion, so that the inspection and maintenance requie me of Part N.E. are complied with. The location of areas not m be disturbed must be delineated (e.g. with flags, stakes, signs, silt from etc.) on the development site before work begins. 2. All exposed soil areas with a continuous positive slope within 200 lineal feet of a snrface water, oust have temporary erosnn protection or permanent cover for the exposed soil areas year round, according to the following table of slopes and time frames: Type of Slope Time (Maximum time an area can remain open when the area Steeper than 3:1 7 days is not actively being wmtted,) 10:1 to 3:1 14 days Flader than UI I 2L days These meas include constructed storm water management pond side slopes, end any exposed soil areas with a positive slope to a storm water conveyance system, such its a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other natural or true made systems that discharge to a surface water. Temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition conme/e stockpiles, sand stockpiles) are exempt from this requirement but must comply with Part IV.C.5. way• yer 4f�. �larw1 =s=j v NPDES REQUIREMENTS 3.

Pipe outlets must be provided with temporary or permanent energy dissipation within 24 hours of connection to a surface water. C. SEDIMENT CONTROL PRACTICES 1. Sediment control practices must minimize sediment from entering surface waters, including curb and gutter systems and storm sewer inlets. a, Temporary or permanent drainage ditches and sediment basins that we designed as pan of a treatment system (e.g.. ditches with rock check dams) require sediment central practices only as appropriate for site conditions, b. Tithe down gradient treatment system is overloaded, additional upgradient sediment control practices mug be installed ' p sta ed to eliminate the overloading, and the SWPPP must be amended to identify these additional practices as required in Pan DLA , a through c. c. In order to maintain sham flow and minimize rills and/or gullies, there shall be no unbroken slope length of greaterlhan 75 fat for slopes with a grade of 3:1 or steeper. Sediment central practices must be established on al wet pr s I do gradient perimeters before any upgradient land disturbing activities begin. These practices shall remain in place until final stabilization has been established in accordance with Pan N.G. 3. The timing of the installation armistices control practices may be adjusted to accommodate short -tear activities such as clearing or grubbing or passage of vehicles. Any short -teen activity most be completed as quickly as possible and the sediment renal practices must be installed immediately after the activity is completed. However, sediment cenlrol practices must be installed before the next precipitation event even if the activity is not complete. 4. All storm drain inlets man be protected by appropriate HMPe during construction until all sources with potential for discharging to the inter have been stabilized. 5. Temporary soil stockpiles must have silt fence or other effective sediment contrah, and cannot be placed in surface waters, including seem water conveyances such as curb and gutter systems, or conduits and ditches. 6. Vehicle tracking of sediment form the construction site must be minimized by BMF. such m stone pads, concrete or steel rash racks, or equivalent systems. Street sweeping must be used if such BMPs ore not adequate to prevent sediment from being tacked onto the street (see Pan N.E.4.d.). 7.

The Permittee(s) must plan for and implement appropriate construction phasing, vegetative buffer strips, horizontal slope grading, and other construction practices that minimize erosion, so that the inspection and maintenance require run of Part N.E. are complied with. The location offences not to be disturbed must be delineated (e.g. with flags, sakes, signs, silt fence etc.) on the development site before work begins. 2. All exposed soil areas with a continuous positive slope within 200 lineal feet of a surface water, must have temporary erosion protection or Permanrnt cover for the exposed soil areas year round, according to the following table of slopes and time frames: Tote of Sloce Time (Maximum time an area can remain open when the aura Steeper than 3:1 7 days is not actively being worked.) 10:1 to 3:1 14 days Flaffer Nat 10:1 21 days These areas include constructed storm water management pond side slopes, and any exposed soil areas with a positive slope to a storm water conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or patmanen[ drainage ditch or other natural or man made systems that discharge to a surface water. Temporary stockpiles without significant silt, clay m organic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, send stockpiles) are exempt from this requirement but must comply with Part IV.C.5. a s •a r- +/ ,A F s S�C NPDES REQUIREMENTS 3. Then normal wetted edmete of an temporary permanent drainage ' that drains o p r y po ary or p ag ditch am water from a construction site, or diverts water wound a site, must be stabilized within 200 lineal feet from the property edge, or from the point of discharge to any surface water. Stabilization must be completed within 24 hours of connecting to a surface water. 4. Pipe outlets tougher provided with temporary or permanent energy dissipation within 24 hours of connection to a surface water. C. SEDIMENT CONTROL PRACTICES 1. Sediment natural practices must minimize sediment from entering surface waters, including curb and gutter systems and storm sewer inlets. a. Temporary or permanent drainage ditches and xdiment basins that are designed as art are treatment stem e.. ditches with mek check dams require sediment P only = central practices ono as appropriate for site conditions. P Y b. B the dawn gradient medical system is overloaded, additional upgradieut sediment central practices must be installed to eliminate the overloading, and the SWPPP most be amended to identify these additional practices as requited in Part III.A.4, a through c. c. In order to maintain sheet flow and minimize rills and/or gullies, there shall be no unbroken slope length of greater than 75 feet for slopes with a grade of 3:1 or steeper. 2. Sediment control practices must be established on all down gradient ermeters before P 6 P any upgmdient land disturbing activities begin. These practices shall remain in place until final stabiff rtion has been established in accordance with Part IV.G. 3. The timing of the installation of sediment central practices may be adjusted to accommodate short -tern activities such as claming or grabbing, or passage ofvehicles. Any short-term activity on be completed as quickly as possible and the sediment control practices most be installed immediately after the activity is completed. However, sediment coutol practices must be installed before the next precipitation event even if the activity is not complete. 4. All storm drain inlets moat he protected by appropriate Ell during construction until all sources with potential for discharging to the inlet have been stabilized. 5. Temporary soil stockpiles must have silt fence or other effective sediment coutmb, and cannot be placed in surface waters, including storm water conveyances such as curb and gutter systems, or conduits and ditches. 6. Vehicle backing of sediment from the construction site must be minimized by BMPs such as stone pads, concrete or steel wash mcks, or equivalent systems. Street sweeping must be used Wench BMPs are not adequate in prevent sediment form being tracked onto the street (see Part N.E.4.d.). 7. The Permittee most install temporary sedimentation basins as required in Part ITS. of this permit, D. DEWATERING AND BASIN DRAUdING 1.

Box 147 • Chanhassen, MN 55317 Name of Applicant: City of Chanhassen. Project Location: Pioneer Pass (Peterson Parcel) (NW 1/4 Section 26 and NE'/4 Section 27, Township 116N, R23W) Type of Application (check one): ❑ Delineation Decision ❑ Exemption Decision ❑ No Loss Decision Replacement Plan Decision ❑ Banking Plan Decision Date of Decision: May 26, 2006 Findings and Conclusions The City of Chanhassen, LGU, has made a replacement plan decision approving the wetland Impacts associated with the Pioneer Pass development in the Chanhassen 2005 MUSA area. Impacts are limited to filling of type 1 wetland basin I (.47 acres). Replacement wetland will be created on site with .48 acres of New Wetland Credit and 1.22 acres of Public Value Credit. The applicant considered the no -build option as well as the total avoidance option in sequencing discussions, however both were dismissed as infeasible. Wetland I is considered a severly degraded basin due to a high level of disturbance and fam ing activities that have historically occurred around and through the basin. The basin is also predominately fed by surface water which will be cut off during the development of the site.

Horton, Inc. February 22, 2006 ' Introduction and Background S1095 Westland Drive Soring Valley, WI 54767 Phone: 715-778-5730 / 888-279-2070 Fax: 715-778-5867 / 888-279-2069 ' The proposed project is located in portions of the NW '/4, Section 26 and NE '/4 of Section 27, T116N, R23W, Carver County, Minnesota. Pioneer Trail crosses the southern portion of the property and croplands, forested slopes, forested ' tributaries and individual farms border the west, north and eastern portions of the property (Figure 1). According to the U.S.G.S. Shakopee Quadrangle (Figure 2), elevations change significantly from the Bluff Creek floodplain and other tributaries to the highest elevations located at the center of the site. Seven wetlands are located throughout the site with cropland, old pasture, fencerows, wooded slopes and an abandoned home located on the upland areas. On ' October 14, 2005, GES evaluated the site for jurisdictional wetlands and found seven on the site. A subsequent review of Farm Service Agency aerial photographs and consultation with city staff on the site identified an eighth wetland that was flagged with city staff on January 12, 2006. The approximate site and wetland boundaries are shown on a 2003 aerial photograph in Figure 3. ' The project involves constructing a single-family residential subdivision and associated infrastructure. A total of 81 detached single-family residential units, 3 storm water ponds, 22.75 acres of open space (parks, wetland mitigation and ' bluff creek overlay (protection area)), and one (1) wetland mitigation area are planned on the Peterson Property. Parcel access would be from Pioneer Trail (County Route 14). rfhis road is located on the southern border of the property. ' One main north/south collector (Street D) is proposed that would connect to a secondmainr c411Prtnr Street lnrated west of the Peterson Property that is being planned and constructed by the City of Chanhassen. WCA/CWA Wetland Application D.R. Horton — Peterson Property GES Project No. 2006.012 February 22, 2006 Page 2 On -Site Wetlands Seven jurisdictional wetlands totaling 10.94 acres were delineated on October 14, and an eighth wetland was delineated and reviewed by the City of Chanhassen on January 12, 2006. A detailed description of each wetland can be found in the Wetland Delineation Report in Appendix A. Brief descriptions of each wetland impacted by the proposed project are included below with jurisdictional details provided in the delineation report (Appendix A). Section 404 Jurisdiction Wetlands A, D, E, F, G, H and I on the Peterson Property are part of a tributary system that feeds both "navigable waters" and interstate waters as they empty into two different branches of Bluff Creek, a tributary to the Minnesota River. Therefore, the Corps of Engineers will have direct regulatory jurisdiction on any wetlands connected to Bluff Creek and to the creek itself under Section 404 of the Clean Water Act. The Corps considers impacts to these wetlands as well as any other wetlands as part of its public interest review. DNR Protected Waters Jurisdiction The Minnesota DNR Protected Waters Inventory (Figure 4) does not map any protected waters or wetlands on the site. Project Need and Purpose The purpose of the project is to provide residential housing in a highly desirable residential sector of the Twin Cities housing market. A need for additional residential options continues to exist in this market. The site is currently zoned for agricultural use but is proposed to be re -zoned for low/medium density single family residential by the City of Chanhassen. Summary of Proposed Impacts A total of 20,473 square feet (0.47 acre) of wetland is proposed to be filled by the project. Proposed impacts will affect all of Wetland I. WCA/CWA Wetland Application D.R. Horton — Peterson Property GES Project No. 2006.012 February 22, 2006 Page 3 Sequencing Avoidance and Minimization Avoidance Alternatives The applicant has tried to avoid and minimize wetland impacts on the project site to the extent practicable. The applicant considered two alternatives that would totally avoid wetland impacts. These alternatives are: No Action Alternative One alternative is the no action alternative, which would result in the project site remaining undeveloped. This alternative is considered infeasible because it would defeat reasonable investment backed expectations of the current landowners and would not fulfill the project purpose. Leaving the site undeveloped would also be inconsistent with the City of Chanhassen's adopted comprehensive plan, feasibility study for public street and utility improvements, and Alternative Urban Areawide Review in support of development of the Peterson Property and adjacent properties. ® Total Avoidance Build Alternative The applicant weighed several factors in their site selection process. A willing seller was one reason for choosing this site; however, additional factors included: price, proximity to major roads, availability of utility services, natural amenities, and proposed zoning by the City of Chanhassen. In addition to these considerations the applicant also pursued total avoidance of wetland impacts by considering alternative sites which could serve the project purpose. Several property owners near the Peterson Property were approached by the applicant to sell their property but were unwilling to sell, had sold to other developers, wanted more than the land was worth, or for a variety of reasons, a transaction could not be worked out. The total avoidance alternative would avoid wetland impacts; however, this alternative would not accomplish the project purpose and would leave large upland portions of the site undeveloped. Given the degraded nature of Wetland I and presence of sub -surface tiling (which eliminates a significant source of wetland hydrology) it is unreasonable to expect this parcel would not be developed. Wetland I's functions are limited. This wetland is also partially drained, is overgrown with annual pioneering and invasive species that limit their value as a source of wildlife habitat or its aesthetic value. WCA/CWA Wetland Application D.R. Horton — Peterson Property GES Project No. 2006.012 February 22, 2006 Page 4 Specific Wetland Impacts and Justification Minimization Impacts to Wetland I are practically impossible to avoid given the site topography and the requirement to provide a road connection to other road alignments west of the Peterson Property and to the proposed Highway 212/312 improvements. The proposed road grade for Street D is designed to meet minimum curve radii and horizontal alignments to align with a round -about that will connect roads that run north -south and east -west along the western property boundary. The north - south and east -west roads were approved by the City of Chanhassen. The wetland impact of 0.47 acre represents less than five percent of the on -site wetlands. The primary purpose of the proposed wetland impacts is street construction that will be designed to provide access for emergency vehicles and to provide a safe driving environment. Sequencing Flexibility As described below, the applicant has considered the possibility of developing ' the project site in a manner that totally avoids the filling of Wetland I. However, given the high level of disturbance, the history of farming, and alterations that have taken place within Wetland I, the applicant is requesting the application of the sequencing flexibility provisions contained in the WCA Rules (Minn. Rules 8420.0520 Subp. 7(a) B). According to these rules; "[fjlexibility in application of the sequencing steps may be applied, subject to the conditions in item A, as determined by the local government unit if: ' (1) the wetland to be impacted has been degraded to the point where replacement of it would result in a certain gain in function and public value; (2) preservation of a wetland would result in severe degradation of the wetland's ability to function and provide public values, for ' example, because of surrounding land uses and the wetland's ability to function and provide public values cannot reasonably be maintained through other land use controls or mechanisms; The U.S. Army Corps of Engineers has similar sequencing flexibility guidance, set forth in Regulatory Guidance Letter 93-2 Guidance on Flexibility of the ' 404(b)(1) Guidelines and Mitigation Banking (RGL 93-2) which states that the degree of scrutiny of project alternatives should be commensurate with the severity of the project impact and that different wetlands have varying functions 1 ' WCA/CWA Wetland Application D.R. Horton — Peterson Property GES Project No. 2006.012 t February 22, 2006 Page 5 ' and values. This guidance provides that "...for projects that would cause only minor or negligible impacts, a detailed analysis of project alternatives should not be conducted". This document further states that minor impacts have one, and frequently more, of the following characteristics: (1) they occur in wetlands which ' perform limited functions, (2) they are small in size (less than one acre), (3) they have little potential for secondary or cumulative impacts, and/or (4) only cause temporary impacts (less than one year). ' Due to the invasive nature of the plant communities that occur in Wetland I and the wetland's small size, the applicant submits that sequencing flexibility ' appropriately applies to the proposed impacts. All of the affected wetland is dominated by invasive annuals such as barnyard grass, cocklebur, and Pennsylvania smartweed and retains little of its ecological integrity. ' MNRAM Functional Assessment Methods ' We have attempted to provide a general abiotic assessment of Wetland I that includes the geomorphic setting (i.e. presence of inlets or outlets) and a description of the water source based upon soil types and position within the ' landscape. The applicant has utilized a methodology that is pre -approved under the WCA. A functional assessment for Wetland I (identified as wetland 27-116-23-26-001-1 in the MNRAM Wetland Functions Summary Assessment) was conducted using Version 3.0 of the Minnesota Routine Assessment Methodology (MNRAM) for Evaluating Wetland Functions written by the Minnesota Board of Water and Soil Resources in April 2004. This methodology is pre -approved by the Minnesota Board of Water and Soil Resources to determine public values of wetlands under ' the jurisdiction of local regulators administering the Wetland Conservation Act. A summary of the wetland functions for the wetland (pre- and post- development) is included in Appendix B. Based on the results of this analysis, the applicant ' submits that the proposed replacement wetland (identified as wetland 27-116-23- 26-000-M in the MNRAM Wetland Functions Summary Assessment) will result in a certain gain in function and public value over the affected wetland. ' Wetland I Wetland I is an isolated depression that receives wetland hydrology via surface water runoff and is dominated by invasive annual species. This wetland currently ' provides limited wildlife habitat because aerial photographs indicate it was farmed every year since 1979. Its dominance by invasive annuals does not add to the species diversity of plant communities within this region and its small size, ' along with its tiled and ditched condition, limit its function for storm water storage. --)�,AII of Wetland I is proposed to be impacted by grading for the construction of a main collector street (Street D) that will serve single family residential homes WCA/CWA Wetland Application D.R. Horton — Peterson Property GES Project No. 2006.012 February 22, 2006 Page 6 throughout the site and will provide a connection to approved projects to the west of the Peterson Property. Minimization and avoidance rationale for Wetland I include the following design alternatives: 1. Public health and safety is better served by constructing a through street rather than by two cul-de-sacs that would avoid impacts to Wetland I. A through street improves access to emergency vehicles by allowing two points of entry and eliminating the necessity of designing cul-de-sacs that allow turning radii for large emergency vehicles. Cul-de-sacs would still impact portions of Wetland I and would divert surface water from the wetland resulting in further degradation over time. 2. It is environmentally preferable to fill Wetland I for a through street and house lots and replace its limited functions in an area that will be monitored, maintained as wetland and protected with a conservation easement elsewhere on -site. The proposed alignment of the street will bisect Wetland I leaving two very small slivers of wetland. These remaining wetland areas if left alone will have approximately 100 percent of the contributing surface water runoff diverted by impervious surfaces and into storm water drains. Therefore, greater wetland function will be provided in the created mitigation area than by allowing existing wetland slivers to remain in areas that may not have wetland hydrology once the project is constructed. 3. By avoiding fill to Wetland A and developing uplands adjacent to the wetland (which would not be regulated), the proposed development would still alter contributing hydrology sources by changing the grading on adjacent upland areas and further reduce the function of the wetland over time. The loss of function over time, the isolated nature of the wetland, and the small size of Wetland I make replacement the environmentally preferable option for this basin. Alternative Sites Alternative sites for the proposed project were not explored in depth since none were available and this site will accomplish the project purpose. Rectification of Impact No temporary wetland impacts are proposed which could be rectified after project completion. Reduction or Elimination of Impacts Over Time ' Standard erosion control measures will be used during construction of the project. Once disturbed areas are revegetated, erosion and sedimentation should not be a problem given the relatively flat topography of the site. WCA/CWA Wetland Application D.R. Horton — Peterson Property GES Project No. 2006.012 February 22, 2006 Page 7 Replacement of Unavoidable Impacts The unavoidable wetland impact of 20,473 square feet (0.47 acres) will be replaced through the implementation of the on -site compensatory mitigation plan outlined below. Compensatory Mitigation Plan The Wetland Conservation Act requires replacement of drained, filled, or in some cases, excavated wetlands at a minimum ratio of 2:1. This equates to a total mitigation requirement for the project of 40,946 square feet or 0.94 acre for the regulable impacts. New Wetland Credit (NWC) is being generated by the applicant through the creation of mitigation wetlands at one location adjacent to the Bluff Creek floodplain. Mitigation wetlands will be created in areas adjacent to Bluff Creek on the north-western portion of the property (see Grading Plan). The total NWC proposed for the site is 20,830 square feet (0.48 acre) which meets requirements under current regulatory programs. The remaining wetland mitigation credits are being generated through the use of upland buffers (10,190 square feet or 0.23 acres), and storm water ponds (43,124 square feet or 0.99 acres) as Public Value Credit. The WCA rules allow Public Value Credit for 100 percent of the normal pool area for storm water ponds in cities with approved storm water management plans. Public Value Credit is needed to comply with WCA regulations on this site. The City of Chanhassen has an approved storm water management plan and the applicant is proposing to construct three storm water ponds on the Peterson Property. The presence of an approved storm water management plan at the City of Chanhassen will allow the applicant to utilize the 43,124 square feet (0.99 acres) of storm water ponding as Public Value Credit. This on -site mitigation plan replaces the wetland fill areas as close to the impact sites as possible. The applicant will be providing mitigation credits exceeding regulatory requirements. A total of 74,144 square feet (1.70 acres) of mitigation credits will be created for 20,473 square feet (0.47 acre) of impact, which is slightly more than a 3.6:1 ratio of restored/created wetland vs. impacted wetland. The WCA requires a 2:1 replacement ratio. New Wetland Credit New Wetland Credit will be generated by the project through the creation of mitigation wetland. The mitigation site will be constructed at one location adjacent to Bluff Creek by excavating to existing groundwater levels and to topographic elevations consistent with delineated wetlands nearby. New wetland areas from the normal water level to one foot above the normal water level will be seeded with a wet meadow seed mix developed and approved by the Minnesota Board of Water and Soil Resources (see Appendix C). The mitigation area lies WCA/CWA Wetland Application D.R. Horton — Peterson Property GES Project No. 2006.012 February 22, 2006 Page 8 within areas mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes (see Figure 5, Appendix A, Delineation Report) on the Carver County Soil Survey. The Vegetation Management Plan is attached in Appendix C as required by the WCA and the COE. The proposed mitigation plan is designed to produce a temporarily flooded wetland type or Circular 39 Type 1 seasonally flooded basin (Peterson Mitigation and Cross Sections) measuring 20,830 square feet (0.48 acre). The new wetland areas will be allowed to re -vegetate below the normal water line and will be planted in a native upland buffer seed mix from the projected wetland boundary to the proposed upland buffer boundary. The mitigation wetlands are expected to generate a mosaic of open water and emergent vegetation. The existing vegetation in adjacent wetlands is comprised of reed canary grass monotypes and mitigation areas will be managed to maintain native grasses and forbs. The mitigation area will be excavated from upland areas that are currently dominated by smooth brome. A permanent conservation easement will be placed over the mitigation areas. Monitoring The mitigation monitoring requirements outlined in the Wetland Conservation Act will be followed. These requirements (per Minn. Rule 8420.0620) are as follows: 1) Description of the project location, size, current wetland type (Cowardin classification), and desired wetland type (goal). 2) A comparison of the as -built specifications versus the design specifications (first annual monitoring report only) and a rationale for significant changes. 3) Hydrology measurements: seasonal water level elevations or areal coverage measurements during the period April through October. 4) A map of plant communities within the boundaries of the replacement site, including hydrologic indicators observed. 5) Color photographs of the project area taken any time during the growing season. Annual mitigation monitoring reports will be prepared and submitted to the City of Chanhassen and copies provided to the U.S. Army Corps of Engineers as required in their respective permits and approvals. f4113 V 10 Approximate Site Location Lae 7r, L L Blvd r b A IL EYAXI�reek Go" ialeer ASwastion f N 16.mlae Park lot — A, A T e G Figure 1.

(GES) has completed the site evaluation for jurisdictional wetlands on a parcel located in portions of the NW Y., Section 26 and NE Y. of Section 27, T116N, R23W, Carver County, Minnesota. Pioneer Trail crosses the southern portion of the property and croplands, forested slopes, forested tributaries and individual farms border the west, north and eastern portions of the property (Figure 1). According to the U.S.G.S. Shakopee Quadrangle (Figure 2), elevations change significantly from the Bluff Creek floodplain and other tributaries to the highest elevations located at the center of the site. Seven wetlands are located throughout the site with cropland, old pasture, fencerows, wooded slopes and an abandoned home located on the upland areas. On October 14, 2005, GES evaluated the site for jurisdictional wetlands and found seven on the site. The approximate site and wetland boundaries are shown on a 2003 aerial photograph in Figure 3. Methodologies The site was assessed for wetlands using the on -site methods contained in the "Routine Determinations" section of the U.S. Army Corps of Engineers "Wetlands Delineation Manuaf' (Technical Report Y-87-1, 1987). This is the methodology currently used by both the U.S. Army Corps of Engineers for implementation of Section 404 of the Clean Water Act and by local government units administering the Minnesota Wetland Conservation Act. GES classified the wetlands under the U.S. Fish and Wildlife Service (FWS) Cowardin system and Circular 39 methodologies. Peterson Property Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 2 of 8 Results Wetland A Wetland A is located along the western boundary of the property. This wetland is an isolated depression along the fenceline that defines the edge of the Peterson site with an adjacent farm field. Past farming activities have elevated sediment and nutrient levels accumulating within the wetland. This wetland is predominantly a reed canary grass monotype with annual weed species located at the transition between the reed canary grass monotype and cropped upland areas. Upland plant communities are comprised of soybeans and corn. Dominant wetland vegetation includes: reed canary grass (Phalaris arundinacea) with other species occurring as subdominants. The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) maps this area as a ditched seasonally flooded palustrine emergent wetland (PEM1Cd). GES would classify this wetland as a ditched temporarily flooded palustrine emergent wetland (PEM1Ad) or as Circular 39 Type 2 inland fresh meadow. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. This wetland receives significant runoff from adjacent cropland and much of the soil profile was obscured by accumulated overwash sediments. Soils in Wetland A are described as 30 inches of dark brown (Munsell matrix color 10YR 3/1) silty loam with bright mottles (10YR 4/6) to 30 inches. The Carver County Soil Survey (Figure 6) map soils in the vicinity of Wetland A as Hamel soils (WM). The colors and textures of soils observed along basin transacts are consistent with Hamel loams. Upland soil profiles exhibited mixed silt loams with dark brown matrix colors (10YR 3/2) for 6 inches over gray -brown loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny loams (KC2) on 6 to 12 percent slopes. Free water was present at the surface in sample points at the wetland center and were present within 8 inches of the soil surface at transitional soil pits. It is also important to note that the evaluation took place after rainfall events of over 5 inches had occurred ten days prior to the evaluation. The wetland hydrology parameter in this wetland was met by documenting one primary indicator (surface water) at the wetland center and by two secondary indicators (FAC neutral vegetation) and using professional judgment at the transition between wetland and upland. No free water or evidence of saturation were observed at upland locations. Peterson Property Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 3 of 8 The jurisdictional boundary was established at the change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by crops. Wetland B Wetland B is located along the Bluff Creek floodplain and in minor topographic ravines that focus overland flow to lower elevations on the site. This wetland occupies the northeastern portion of the site. Upland areas adjacent this wetland are comprised of old field plant communities on slopes that face south and east and by croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass, American elm (Ulmus americana), spotted jewelweed (Impatiens capensis), and the presence of plant species that are often associated with disturbed ground such as sandbar willow (Salix exigua), black willow (Salix nigra), giant goldenrod (Solidago gigantea), and yellow foxtail (Setaria glauca). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) maps only the most northwestern corner of the site. GES would classify a larger area as a seasonally flooded palustrine emergent/forested wetland (PEM/FO1C) or as Circular 39 Type 3/7 inland shallow marsh/wooded swamp. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland B are described as 13 inches of dark brown (Munsell matrix color 10YR 3/2) silty loam followed by black (10YR 2/1) loams to 24 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland B as Hamel loams (HM) or Houghton and Muskego soils (MK). The colors and textures of soils observed along basin transects are consistent with a variant of Hamel soils. Upland soil profiles exhibited mixed sandy loams with dark brown matrix colors (10YR 3/2) for 6 inches over bright yellow clay loam (10YR 4/3). Upland soils are mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes. The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by pioneering grasses, forbs or crops. Wetland C Wetland C is located adjacent to Pioneer Trail on the southern portion of the site. It is also located at the base of significant slopes to the north. The natural outlet has been blocked by the construction of a driveway at the western edge of the wetland and has probably been made wetter by the construction of roads and driveways next to the wetland. The center of the wetland was entirely open water at the time of the delineation and Peterson Property Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 4 of 8 was characterized by concentric rings of annual hydrophytic vegetation at the wetland/upland transition. Upland areas adjacent this wetland are comprised of croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass, green ash (Fraxinus pennsylvanica), switch grass (Panicum virgatum), and the presence of plant species that are often associated with disturbed ground such as giant ragweed (Ambrosia trifida), black willow, Iamb's quarters (Chenopodium album), and water smartweed (Polygonum amphibium). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify a this area as a seasonally flooded palustrine emergent wetland (PEMC) or as Circular 39 Type 3 inland shallow marsh. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland C are described as 14 inches of dark ' brown (Munsell matrix color 10YR 2/1) silty loam followed by black (10YR 2/1) loams to 20 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland C as Glencoe clay loams (GL). The colors ' and textures of soils observed along basin transects are consistent with a variant of Hamel soils or of an accumulation of eroded sediments from surrounding uplands. Upland soil profiles exhibited mixed silty clay loams with dark brown matrix colors (10YR 4/3) for 12 inches over bright yellow clay loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes. This wetland is an isolated depression that appears to be reliant upon surface runoff to maintain wetland hydrology. The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by crops. Wetland D Wetland D is located adjacent to Pioneer Trail on the southern portion of the site. It is also located at the base of significant slopes to the north. A natural connection to Wetland C has been blocked by the construction of a driveway at the eastern edge of the wetland. Upland areas adjacent this wetland are comprised of croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass, switch grass, and the presence of plant species that are often associated with disturbed ground such as giant ragweed, Iamb's quarters, and cocklbur (Xanthium strumarium). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a temporarily flooded ' Peterson Property Wetland Delineation Report GES Project No. 2005.133 ' December 6, 2005 Page 5 of 8 palustrine emergent wetland (PEMA) or as Circular 39 Type 2 inland fresh meadow.

Soils in Wetland D are described as 6 inches of dark ' brown (Munsell matrix color 10YR 4/2) silty loam followed by black (10YR 2/1) clay loams to 20 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland D as Cordova -Webster complex (CW). The colors and textures of soils observed along basin transects are ' consistent with a variant of Hamel soils or of an accumulation of eroded sediments from surrounding uplands. Upland soil profiles exhibited clay loams with brown matrix colors (10YR 4/2) for 14 inches over gray -brown ' clay loam (10YR 4/1).

Wetland E Wetland E is located along the Bluff Creek floodplain and in minor topographic ravines that focus overland flow to lower elevations on the site. This wetland occupies the eastern portion of the site. Upland areas adjacent this wetland are comprised of old field plant communities on slopes that face north and by croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass with subdominants including Joe-pye weed (Eupatorium maculatum), stinging nettle (Urtica dioica), redtop (Agrostis alba), and lady's thumb (Polygonum persicaria). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a temporarily flooded palustrine emergent wetland (PEMA) or as Circular 39 Type 2 inland fresh meadow. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland E are described as 14 inches of dark brown (Munsell matrix color 10YR 3/1) silty loam followed by dark brown (10YR 3/1) loams to 30 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland E as Klossner muck (PM) or Hamel soils (HM). The colors and textures of soils observed along basin Peterson Property Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 6 of 8 transects are consistent with a variant of Hamel soils. Upland soil profiles exhibited mixed silt loams with dark brown matrix colors (10YR 3/1) for 34 inches. Upland soils are mapped as Lester -Kilkenny soils (KC2) on 6 to 12 percent slopes. The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by pioneering grasses, (orbs or crops. Wetland F Wetland F is located along a tributary floodplain that flows to the Minnesota River and in minor topographic ravines that were created by down -cutting at drain tile outlets. This wetland occupies a small portion of the southwestern corner of the site. Upland areas adjacent this wetland are comprised of sugar maple forest on steep slopes on either side of the tributary. Dominant wetland vegetation is scarce within the bottom of the ravine but includes: duckweed (Lemna minor). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a seasonally flooded palustrine emergent wetland (PEM1C) or as Circular 39 Type 3 inland fresh marsh. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland F are described as 32 inches of accumulated sediments that are dark brown (Munsell matrix color 10YR 3/1). The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland F as Lester -Kilkenny foams (KF). The colors and textures of soils observed along basin transects are consistent with a variant of Hamel soils. Upland soil profiles exhibited silt loams with dark brown matrix colors (10YR 3/2) for 5 inches followed by 18 inches of gray -brown clay loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny soils (KD2) on 12 to 18 percent slopes. The jurisdictional boundary was established at an abrupt rise in topography. ' Wetland G Wetland G is located along the Bluff Creek floodplain and is surrounded by high quality sugar maple forest at the southeastern portion of the site. Dominant wetland vegetation includes: reed canary grass and wood nettle (Laportea canadensis) with subdominants including eastern cottonwood (Populus deltoides), white snakeroot (Eupatorium rugosum), box elder (Acer negundo), and black willow.

Soils in Wetland G are described as 12 inches of accumulated sediments that are dark brown (Munsell matrix color 10YR 411) followed by 8 inches of black loam (N3/0). The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland G as Lester - Kilkenny loams (KF). The colors and textures of soils observed along basin transects are consistent with floodplain soils in depositional areas of riverine systems. Upland soil profiles exhibited silt loams with dark brown matrix colors (10YR 3/2) for 5 inches followed by 18 inches of gray -brown clay loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny soils (KD2) on 12 to 18 percent slopes. The jurisdictional boundary was established at an abrupt rise in topography. Regulatory Jurisdiction Minnesota DNR Protected Waters The Minnesota DNR Protected Waters Inventory (Figure 7) does not map any protected waters or wetlands on the site. Minnesota Wetland Conservation Act The jurisdictional wetlands that were identified on the subject parcel are subject to the Wetland Conservation Act Rules Chapter 8420. Federal Regulatory Jurisdiction The enclosed wetland delineation data forms indicated whether wetlands are isolated or not for purposes of U.S. Army Corps of Engineers jurisdiction under Section 404 of the Clean Water Act. This determination is made by GES in the field at the time of the delineation and is essentially our best guess based on the portion of the particular wetland we observe. In some cases, only a small portion of the wetland edge is evaluated. If no inlets or outlets are observed in the evaluated area, and none are evident on U.S.G.S. topographic maps or aerial photos, we are inclined to Peterson Property Wetland Delineation Report GES Project No. 2005.133 December 8, 2005 Page 8 of 8 determine the wetland is isolated. However, since the entire wetland is sometimes not assessed, it is possible that inlets and/or outlets do exist and that the wetland has a surface connection to a federal "navigable" water and, thus, falls within the jurisdiction of Section 404. Therefore, a determination by GES of whether a particular wetland is isolated or not should not be considered a final determination with regard to Corps jurisdiction. Concurrence with our findings should be obtained from the U.S. Army Corps of Engineers, Carver County, and the City of Chanhassen before any earthwork is undertaken on the site. Additional information regarding the vegetation, soils and hydrology of the wetlands are included in Appendix A. Ground photos of all the areas evaluated for jurisdictional criteria are included in Figures 7-10. The information contained herein represents my findings during wetland delineation activities conducted on October 14, 2005 at the referenced site. Graham Environmental Services, Inc.

DATE: December 30, 2005 SUBJECT: Wetland Delineation for D.R. Horton Project, Chanhassen, Minnesota ' As you know, Graham Environmental Services, Inc. (GES) conducted a delineation of wetlands at the above -referenced site (Figure 1) on October 15, 2005. We have provided your office with a copy of our delineation report. Subsequently, the City has indicated that they believe that a depressional area not delineated by GES (Figure 2), ' but delineated previously by Pinnacle Engineering and surveyed by RLK in 2001 (Figure 3), is jurisdictional wetland. The depressional area in question will be called "Area 1" throughout the remainder of this memorandum. Area 1 is located on the northern half of the site southeast of Wetland A, as identified in the GES report. This area occupies a depression that is ' tiled, ditched, and was planted in crops every year since 1985 according to Farm Service Agency (FSA) slides. Sloping cropland borders this depression on all sides. Area 1 is served by an 8-inch drain tile that was actively removing water from the area ' during our delineation activities. The drain tile outlet is located at the southwestern portion of the site in an area that was delineated as Wetland F. ' To further investigate Area 1, GES reviewed all available aerial photographs for the site at the Carver County FSA offices on December 15, 2005. Photographs were available for the years 1985-1994 and 2000. We also reviewed an aerial photograph for 2003 ' from another source as part of our analysis.' Carver County FSA aerial photographs flown annually during the months of June, July, or August were also evaluated to review the site for crop stress due to wetness, inclusion of non -cropped areas within ' cropland, different planting dates, surface water, areas drowned out by accumulated water, areas not planted due to moisture, etc.2 We've summarized our findings below. GES followed guidelines for reviewing FSA aerial photographs established in the August 1994 "State of Minnesota Interagency Cooperative Agreement for Implementation of the Federal Wetland Delineation Memorandum of Agreement" (MOA) between the Natural Resource Conservation Service, the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency, and the U.S. Fish and Wildlife Service. ' 'GES followed the Off -Site Procedures Use of Rainfall Data with ASCS Slides to Determine Hvdrology section of the MOA to evaluate the aerial photographs. These procedures require the use of rainfall spreadsheets from the NOAA weather station nearest to the site. This methodology is especially helpful in evaluating whether or not wetland hydrology exists in cropland areas that are planted or plowed. ' .II�AIII y ' Ms. Lori Haak D.R. Horton Site December 30, 2005 ' Page 2 of 4 ' Hydrology Rainfall data is used to identify whether a specific area has received normal precipitation for an individual year or to establish climatic context for a specific region. Rainfall totals are a way to assess short-term fluctuations in ground and surface water t levels that are important to note when evaluating wetland parameters. Areas that have received above normal rainfall may exhibit wetland hydrology when they would normally be dry. Conversely, areas that receive less than normal precipitation may not exhibit wetland hydrology when they normally would. The climatic context is a longer term evaluation of rainfall totals and may indicate growing season drought, pluvial, or normal periods and are also important to note when evaluating wetland parameters. ' Both rainfall and climactic data are important in areas that are farmed, tiled, ditched or that have numerous temporarily flooded wetlands. Both types of rainfall data are used when conducting on- and off -site evaluations on farmland. The Chaska recording station is the nearest station to the site providing rainfall data. The average annual precipitation for this area according to data from this station is 30.31 inches. Table 1 lists the average monthly rainfall for this area and the departure from normal during the four months prior to our site visit in October. Table 1 onth I Average Monthly T 2005 Recorded Rainfall (inches) Monthly Rainfall (inchembillilik I Departure from Normal (inches) June 4.16 7.26 +3.10 Jul 4.41 2.20 -2.21 Au ust 4.34 4.73 +0.39 September 2.97 9.85 +6.88 October 1 2.14 5.01 +2.87 An data reported from Station 1465, Chaska, Minnesota. A plus (+) sign indicates above average amounts, a minus (-) sign indicates below average amounts. The climatic conditions for this area of the state were 125 percent of normal for the year through October, 110 percent of normal for the year through September, and 100 percent of normal for the year through August. For the southern one-half of Minnesota, the 2005 growing season ended on a very wet note. All-time high monthly rainfall records were set in some communities. For many locations in central and southern Minnesota, September precipitation totals topped seven inches. Rainfall in some locations exceeded ten inches for the month (Minnesota Climatology Working Group Home Page, October 2005). FSA aerial photographs show that there were secondary indicators of crop stress in ' Area 1 in the years 1993, 1994, and 2000. All three of these years were considered wetter than average or drier than average and would not be included in the analysis under MOA procedures. No signatures were present in years which fell within the Ms. Lori Haak D.R. Horton Site December 30, 2005 ' Page 3 of 4 normal precipitation range according to the MOA methodology. The MOA that prescribes how FSA reviews should be conducted requires a summary of the slide review and climate analysis. It also states "That if the number of wet signatures in normal years is > 50 percent, the site will be considered to have wetland hydrology." Since signatures meeting MOA criteria are present in only three of the available 12 ' years (25 percent), the wetland hydrology threshold described in the MOA was not met in Area 1. Vegetation The plant community in Area 1 is dominated by soybeans (Glycine max), pinkweed (Polygonum pensylvanicum, FACW+), barnyard grass (Echinochloa crusgalli, FACW) ' and cocklebur (Xanthium strumarium, FAC) (see attached data sheet for more comprehensive information). Although the vegetation meets wetland criteria per the 1987 Corps of Engineers Wetlands Delineation Manual (1987 Manual), it should be ' noted that these species are all annuals and reflect above -normal precipitation that was present in this area during critical germination periods during the 2005 growing season. Hydric Soils The soils in Area 1 exhibit up to 25 inches of accumulated sediments (eroded deposits) over the original soil surface. The accumulated sediments are dark brown (10YR 3/2) ' silt loams over dark gray/brown (10YR 412) silt loam. Soils exhibited bright (10YR 4/6) mottles to within six inches of the soil surface, but may be oxidation due to farming practices, crop residue, and some water level fluctuation. No inundation or saturation was observed within 16 inches of the soil surface for the soil profiles examined within the depression. ' Conclusion Based on the conditions outlined above and within our delineation report, Area 1 is considered an "atypical situation" as defined in the 1987 Manual due to the effects of ' human activities. This area exhibited a plant community that is dominated by annual weed species some of which are considered hydrophytic and others as upland species. Due to the orientation of the plant species identified in this area, the plant community is ' considered FAC neutral or hydrophytic. Hamel soils are transitional, occurring in sloping areas where shallow depressions or drainages occur on the landscape. These soils were generally created in areas where surface sediments accumulate due to surface runoff. Hamel soils meet the technical definition of hydric soils when there are ' no hydrologic modifications. However, the hydrology that formed these soils historically has been altered by the presence of drain tiles and a shallow surface drain. Area 1 did not exhibit any primary indicators of hydrology or the required two secondary indicators ' (only FAC neutral plant community was present) to be called jurisdictional wetland. It is noteworthy that other similar basins on the site exhibited primary wetland indicators after significant rainfall events in October and as defined by the 1987 Manual. In summary, it is our opinion that Area 1 is not technically a jurisdictional wetland. Ms. Lori Haak D.R. Horton Site December 30, 2005 Page 4 of 4 Regardless, the developer has indicated a desire to acquiesce to calling a portion of Area 1 jurisdictional wetland and mitigating for the impacts if we can agree to its size. ' The most recent City correspondence included a hand -sketch of a suggested wetland boundary including approximately two acres. The Pinnacle Engineering delineation and RLK survey completed in 2001 identifies through technical methods a 0.26 acre wetland. Subsequently, this wetland boundary was included on the recently approved concept plan on the property. If the City concurs with the 0.26 acre boundary as the jurisdictional wetland of Area 1, we are prepared to submit a Wetland Replacement ' Plan (WRP) on behalf of the developer, which includes 2:1 mitigation per the Wetland Conservation Act (WCA) for the 0.26 acre area. The mitigation plan would include the possibility of on -site New Wetland Credit (NWC) as well as Public Value Credits on the ' site through the construction of storm water ponds. If NWC on the site proves infeasible, we would appreciate discussing with you the potential of restoring adequate wetland area within another area in the City. We are also in contact with Houston Engineering, who are working on a WRP for the wetland impact of the East-West Collector, regarding the possibility of a joint mitigation effort. ' We would appreciate an opportunity to discuss these issues with you after you have had a chance to review this memorandum. Thank you. Cc: Ron Mullenbach, D.R.

While, the District is not an official member of the TEP, the District can provide comments for projects within the District's watershed boundary. The WRP requests sequencing flexibility to fill Wetland I. However, it is not clear if the applicant has made a good faith effort to avoid and minimize wetland impacts to Wetland I, which may represent an excellent opportunity for wetland restoration. Is it feasible to move the development entrance road, Street D, to to the south, in an attempt to avoid wetland impacts and then route treated stormwater to the wetland? The other issues I have are minor.

First big thing that I see is that wetland I is being impacted and it says (by others). This wetland is on this property and it appears that the grading for this project is going to impact portions of this wetland. In particular, lot # 5. Is the new road a part of 312 or what. Just want to make sure that we have some sort of documentation on how Wetland I is going to be replaced. Second, the consultant should be made well aware that we are going to hold them to the highest standards for the mitigation area actually turning out to be something. In other words ... the seed mixture planting is going to be growing very well. Give me a shout if you get a chance.

INC. — MINNESOTA Wetland Replacement Plan Wetland Conservation Act Section 404 Clean Water Act Peterson Property City of Chanhassen, Minnesota Applicant: D.R. Horton, Inc. February 20, 2006 Introduction and Background The proposed project is located in portions of the NW'/4, Section 26 and NE'/< of Section 27, T116N, R23W, Carver County, Minnesota. Pioneer Trail crosses the southern portion of the property and croplands, forested slopes, forested tributaries and individual farms border the west, north and eastern portions of the property (Figure 1). According to the U.S.G.S. Shakopee Quadrangle (Figure 2), elevations change significantly from the Bluff Creek floodplain and other tributaries to the highest elevations located at the center of the site. Seven wetlands are located throughout the site with cropland, old pasture, fencerows, wooded slopes and an abandoned home located on the upland areas. On October 14, 2005, GES evaluated the site for jurisdictional wetlands and found seven on the site. A subsequent review of Farm Service Agency aerial photographs and consultation with city staff on the site identified an eighth wetland that was flagged with city staff on January 12, 2006. The approximate site and wetland boundaries are shown on a 2003 aerial photograph in Figure 3. The project involves constructing a single-family residential subdivision and associated infrastructure. A total of 81 detached single-family residential units, storm water ponds, 22.75 acres of open space (parks, wetland mitigation and bluff creek overlay (protection area)), and one (1) wetland mitigation area are ' planned on the Peterson Property. Parcel access would be from Pioneer Trail (County Route 14). This road is located on the southern border of the property. One main north/south collector (Street D) is proposed that would connect to a t second major collector street located west of the Peterson Property that is being planned and constructed by the City of Chanhassen. WCA/CWA Wetland Application t D.R. Horton — Peterson Property GES Project No. 2006.012 February 20, 2006 Page 2 ' On -Site Wetlands t Seven jurisdictional wetlands totaling 10.94 acres were delineated on October 14, and an eighth wetland was delineated and reviewed by the City of Chanhassen on January 12, 2006. A detailed description of each wetland can ' be found in the Wetland Delineation Report in Appendix A. Brief descriptions of each wetland impacted by the proposed project are included below with jurisdictional details provided in the delineation report (Appendix A). ' Section 404 Jurisdiction Wetlands A, D, E, F, G, H and I on the Peterson Property are part of a tributary system that feeds both "navigable waters" and interstate waters as they empty into two different branches of Bluff Creek, a tributary to the Minnesota River. Therefore, the Corps of Engineers will have direct regulatory jurisdiction on any wetlands connected to Bluff Creek and to the creek itself under Section 404 of the Clean Water Act. The Corps considers impacts to these wetlands as well as ' any other wetlands as part of its public interest review. DNR Protected Waters Jurisdiction tThe Minnesota DNR Protected Waters Inventory (Figure 4) does not map any protected waters or wetlands on the site. Project Need and Purpose t The purpose of the project is to provide residential housing in a highly desirable residential sector of the Twin Cities housing market. A need for additional residential options continues to exist in this market. The site is currently zoned ' for agricultural use but is proposed to be re -zoned for low/medium density single family residential by the City of Chanhassen. Summary of Proposed Impacts A total of 20,473 square feet (0.47 acre) of wetland is proposed to be filled by the project. Proposed impacts will affect all of Wetland I. WCA/CWA Wetland Application ' D.R. Horton — Peterson Property GES Project No. 2006.012 February 20, 2006 Page 3 ' Sequencing ' Avoidance and Minimization Avoidance Alternatives ' The applicant has tried to avoid and minimize wetland impacts on the project site to the extent practicable. The applicant considered two alternatives that would totally avoid wetland impacts. These alternatives are: No Action Alternative One alternative is the no action alternative, which would result in the project site remaining undeveloped. This alternative is considered infeasible because it would defeat reasonable investment backed expectations of the current landowners and would not fulfill the project purpose. Leaving the site undeveloped would also be inconsistent with the City of Chanhassen's adopted comprehensive plan, feasibility study for public street and utility improvements, and Alternative Urban Areawide Review in support of development of the Peterson Property and adjacent properties. Total Avoidance Build Alternative The applicant weighed several factors in their site selection process. A willing seller was one reason for choosing this site; however, additional factors included: price, proximity to major roads, availability of utility services, natural amenities, and proposed zoning by the City of Chanhassen. In addition to these considerations the applicant also pursued total avoidance of wetland impacts by considering alternative sites which could serve the project purpose. Several property owners near the Peterson Property were approached by the applicant to sell their property but were unwilling to sell, had sold to other developers, wanted more than the land was worth, or for a variety of reasons, a transaction could not be worked out. The total avoidance alternative would avoid wetland impacts; however, this alternative would not accomplish the project purpose and would leave large upland portions of the site undeveloped. Given the degraded nature of Wetland I and presence of sub -surface tiling (which eliminates a significant source of wetland hydrology) it is unreasonable to expect this parcel would not be developed. Wetland I's functions are limited. This wetland is also partially drained, is overgrown with annual pioneering and invasive species that limit their value as a source of wildlife habitat or its aesthetic value. 1 WCA/CWA Wetland Application ' D.R. Horton — Peterson Property GES Project No. 2006.012 February 20, 2006 Page 4 Specific Wetland Impacts and Justification Minimization Impacts to Wetland I are practically impossible to avoid given the site topography and the requirement to provide a road connection to other road alignments west of the Peterson Property and to the proposed Highway 212/312 improvements. The proposed road grade for Street D is designed to meet minimum curve radii and horizontal alignments to align with a round -about that will connect roads that run north -south and east -west along the western property boundary. The north - south and east -west roads were approved by the City of Chanhassen. The wetland impact of 0.47 acre represents less than five percent of the on -site wetlands. The primary purpose of the proposed wetland impacts is street construction that will be designed to provide access for emergency vehicles and to provide a safe driving environment. Sequencing Flexibility As described below, the applicant has considered the possibility of developing the project site in a manner that totally avoids the filling of Wetland I. However, given the high level of disturbance, the history of farming, and alterations that have taken place within Wetland I, the applicant is requesting the application of the sequencing flexibility provisions contained in the WCA Rules (Minn. Rules 8420.0520 Subp. 7(a) B). According to these rules, "[fjlexibility in application of the sequencing steps may be applied, subject to the conditions in item A, as determined by the local government unit if: (1) the wetland to be impacted has been degraded to the point where replacement of it would result in a certain gain in function and public value; (2) preservation of a wetland would result in severe degradation of the wetland's ability to function and provide public values, for example, because of surrounding land uses and the wetland's ability to function and provide public values cannot reasonably be maintained through other land use controls or mechanisms; The U.S. Army Corps of Engineers has similar sequencing flexibility guidance, set forth in Regulatory Guidance Letter 93-2 Guidance on Flexibility of the 404(b)(1) Guidelines and Mitigation Banking (RGL 93-2) which states that the degree of scrutiny of project alternatives should be commensurate with the severity of the project impact and that different wetlands have varying functions 1 WCA/CWA Wetland Application t D.R. Horton — Peterson Property GES Project No. 2006.012 February 20, 2006 Page 5 ' and values. This guidance provides that "...for projects that would cause only minor or negligible impacts, a detailed analysis of project alternatives should not be conducted". This document further states that minor impacts have one, and frequently more, of the following characteristics: (1) they occur in wetlands which perform limited functions, (2) they are small in size (less than one acre), (3) they ' have little potential for secondary or cumulative impacts, and/or (4) only cause temporary impacts (less than one year). ' Due to the invasive nature of the plant communities that occur in Wetland I and the wetland's small size, the applicant submits that sequencing flexibility appropriately applies to the proposed impacts. All of the affected wetland is ' dominated by invasive annuals such as barnyard grass, cocklebur, and Pennsylvania smartweed and retains little of its ecological integrity. MNRAM Functional Assessment Methods We have attempted to provide a general abiotic assessment of Wetland I that includes the geomorphic setting (i.e. presence of inlets or outlets) and a description of the water source based upon soil types and position within the landscape. The applicant has utilized a methodology that is pre -approved under the WCA. A functional assessment for Wetland I (identified as wetland 27-116-23-26-001-1 in the MNRAM Wetland Functions Summary Assessment) was conducted using Version 3.0 of the Minnesota Routine Assessment Methodology (MNRAM) for Evaluating Wetland Functions written by the Minnesota Board of Water and Soil Resources in April 2004. This methodology is pre -approved by the Minnesota Board of Water and Soil Resources to determine public values of wetlands under the jurisdiction of local regulators administering the Wetland Conservation Act. A summary of the wetland functions for the wetland (pre- and post- development) is included in Appendix B. Based on the results of this analysis, the applicant submits that the proposed replacement wetland (identified as wetland 27-116-23- 26-000-M in the MNRAM Wetland Functions Summary Assessment) will result in a certain gain in function and public value over the affected wetland. t Wetland I Wetland I is an isolated depression that receives wetland hydrology via surface water runoff and is dominated by invasive annual species. This wetland currently ' provides limited wildlife habitat because aerial photographs indicate it was farmed every year since 1979. Its dominance by invasive annuals does not add to the species diversity of plant communities within this region and its small size, ' along with its tiled and ditched condition, limit its function for storm water storage. All of Wetland I is proposed to be impacted by grading for the construction of a main collector street (Street D) that will serve single family residential homes 1 WCA/CWA Wetland Application ! D.R. Horton - Peterson Property GES Project No. 2006.012 February 20, 2006 Page 6 ! throughout the site and will provide a connection to approved projects to the west of the Peterson Property. Minimization and avoidance rationale for Wetland I ! include the following design alternatives: 1. Public health and safety is better served by constructing a through street rather than by two cul-de-sacs that would avoid impacts to Wetland I. A ! through street improves access to emergency vehicles by allowing two points of entry and eliminating the necessity of designing cul-de-sacs that allow turning radii for large emergency vehicles. Cul-de-sacs would still ! impact portions of Wetland I and would divert surface water from the wetland resulting in further degradation over time. 2. It is environmentally preferable to fill Wetland I for a through street and ! house lots and replace its limited functions in an area that will be monitored, maintained as wetland and protected with a conservation easement elsewhere on -site. The proposed alignment of the street will ! bisect Wetland I leaving two very small slivers of wetland. These remaining wetland areas if left alone will have approximately 100 percent of the contributing surface water runoff diverted by impervious surfaces ! and into storm water drains. Therefore, greater wetland function will be provided in the created mitigation area than by allowing existing wetland slivers to remain in areas that may not have wetland hydrology once the ! project is constructed. 3. By avoiding fill to Wetland A and developing uplands adjacent to the wetland (which would not be regulated), the proposed development would ! still alter contributing hydrology sources by changing the grading on adjacent upland areas and further reduce the function of the wetland over time. The loss of function over time, the isolated nature of the wetland, ! and the small size of Wetland I make replacement the environmentally preferable option for this basin. ! Alternative Sites Alternative sites for the proposed project were not explored in depth since none were available and this site will accomplish the project purpose ! Rectification of Impact No temporary wetland impacts are proposed which could be rectified after project ! completion. Reduction or Elimination of Impacts Over Time ! Standard erosion control measures will be used during construction of the project. Once disturbed areas are revegetated, erosion and sedimentation should not be a problem given the relatively flat topography of the site. ! ! ! WCA/CWA Wetland Application ' D.R. Horton — Peterson Property GES Project No. 2006.012 February 20, 2006 Page 7 Replacement of Unavoidable Impacts ' The unavoidable wetland impact of 20,473 square feet (0.47 acres) will be replaced through the implementation of the on -site compensatory mitigation plan outlined below. Compensatory Mitigation Plan t The Wetland Conservation Act requires replacement of drained, filled, or in some cases, excavated wetlands at a minimum ratio of 2:1. This equates to a total mitigation requirement for the project of 40,946 square feet or 0.94 acre for the ' regulable impacts. New Wetland Credit (NWC) is being generated by the applicant through the creation of mitigation wetlands at one location adjacent to the Bluff Creek floodplain. Mitigation wetlands will be created in areas adjacent ' to Bluff Creek on the north-western portion of the property (see Grading Plan). The total NWC proposed for the site is 20,830 square feet (0.48 acre) which meets requirements under current regulatory programs. The remaining wetland mitigation credits are being generated through the use of upland buffers (10,190 square feet or 0.23 acres), and storm water ponds (43,124 square feet or 0.99 acres) as Public Value Credit. The WCA rules allow Public Value Credit for 100 percent of the normal pool area for storm water ponds in cities with approved storm water management plans. Public Value Credit is needed to comply with WCA regulations on this site. The City of Chanhassen has an approved storm water management plan and the applicant is proposing to construct three storm water ponds on the Peterson Property. The presence of an approved storm water management plan at the City of Chanhassen will allow the applicant to utilize the 43,124 square feet (0.99 acres) of storm water ponding as Public Value Credit. This on -site mitigation plan replaces the wetland fill areas as close to the impact sites as possible. The applicant will be providing mitigation credits exceeding regulatory requirements. A total of 74,144 square feet (1,70 acres) of mitigation credits will be created for 20,473 square feet (0.47 acre) of impact, which is slightly more than a 3.6:1 ratio of restored/created wetland vs. impacted wetland. The WCA requires a 2:1 replacement ratio. New Wetland Credit New Wetland Credit will be generated by the project through the creation of mitigation wetland. The mitigation site will be constructed at one location adjacent to Bluff Creek by excavating to existing groundwater levels and to topographic elevations consistent with delineated wetlands nearby. New wetland areas from the normal water level to one foot above the normal water level will be seeded with a wet meadow seed mix developed and approved by the Minnesota Board of Water and Soil Resources (see Appendix C). The mitigation area lies 1 WCA/CWA Wetland Application D.R. Horton — Peterson Property GES Project No. 2006.012 February 20, 2006 Page 8 within areas mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes (see Figure 5, Appendix A, Delineation Report) on the Carver County Soil Survey. The Vegetation Management Plan is attached in Appendix C as required by the WCA and the COE. The proposed mitigation plan is designed to produce a temporarily flooded wetland type or Circular 39 Type 1 seasonally flooded basin (Peterson Mitigation and Cross Sections) measuring 20,830 square feet (0.48 acre). The new wetland areas will be allowed to re -vegetate below the normal water line and will be planted in a native upland buffer seed mix from the projected wetland boundary to the proposed upland buffer boundary. The mitigation wetlands are expected to generate a mosaic of open water and emergent vegetation. The existing vegetation in adjacent wetlands is comprised of reed canary grass monotypes and mitigation areas will be managed to maintain native grasses and forbs. The mitigation area will be excavated from upland areas that are currently dominated by smooth brome. A permanent conservation easement will be placed over the mitigation areas. Monitoring The mitigation monitoring requirements outlined in the Wetland Conservation Act will be followed. These requirements (per Minn. Rule 8420.0620) are as follows: 1) Description of the project location, size, current wetland type (Cowardin classification), and desired wetland type (goal). 2) A comparison of the as -built specifications versus the design specifications (first annual monitoring report only) and a rationale for significant changes. 3) Hydrology measurements: seasonal water level elevations or areal coverage measurements during the period April through October. 4) A map of plant communities within the boundaries of the replacement site, including hydrologic indicators observed. 5) Color photographs of the project area taken any time during the growing season. Annual mitigation monitoring reports will be prepared and submitted to the City of Chanhassen and copies provided to the U.S. Army Corps of Engineers as required in their respective permits and approvals. 5 Aqb oa ,ChW,,ewsl W 78th EA coucar Blvd Yctoria 9 W o u 13 R 41 a 19 o Marsh �1 a P%kApproximate m Ma°rsPAath aimT RLaickee $ Site Location Pv er �y L � � � I.Yrrbn BNtl Rlq Late �taze�kle RrleyLake HaZekkte Nabor91 Gdt Ckk p n 101 1 0 [Yr811 Prairie aa1etYSC� 17 / BkiH Creek PioneerJDnebw Park Aswclllon Itrltldkoerk Rd $ 4 , Frl'll4iCp'A Rice Lake 11 � Chaska cornneeviyCeri V' 212AV 4t 12 Riv.ersi .e Perk ...........: ...............: ers W m 9 PSi Sst AveE MO 101- yl o 1¢ Ave_ ` e* T'-�a ..... ..... .., .vlAve to Ave W' A 3rd • e N� W Ave �1akc N 1m z _ Chaska EAp1 5k - �� WithAve W 101h Ave E n 1Q ^z' C 15 17 r Lions V01110 c lmam •ewoac .aaa a! c.lir 1a .!eea' Park v"%G ►'E Figure 1.

(GES) has completed the site evaluation for jurisdictional wetlands on a parcel located in portions of the NW'/<, Section 26 and NE'/<of Section 27, T116N, R23W, Carver County, Minnesota. Pioneer Trail crosses the southern portion of the property and croplands, forested slopes, forested tributaries and individual farms border the west, north and eastern portions of the property (Figure 1). According to the U.S.G.S. Shakopee Quadrangle (Figure 2), elevations change significantly from the Bluff Creek floodplain and other tributaries to the highest elevations located at the center of the site. Seven wetlands are located throughout the site with cropland, old pasture, fencerows, wooded slopes and an abandoned home located on the upland areas. On October 14, 2005, GES evaluated the site for jurisdictional wetlands and found seven on the site. The approximate site and wetland boundaries are shown on a 2003 aerial photograph in Figure 3. Methodologies The site was assessed for wetlands using the on -site methods contained in the "Routine Determinations" section of the U.S. Army Corps of Engineers "Wetlands Delineation Manuaf' (Technical Report Y-87-1, 1987). This is the methodology currently used by both the U.S. Army Corps of Engineers for implementation of Section 404 of the Clean Water Act and by local government units administering the Minnesota Wetland Conservation Act. GES classified the wetlands under the U.S. Fish and Wildlife Service (FWS) Cowardin system and Circular 39 methodologies. 1 Peterson Property ' Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 2 of 8 Results ' Wetland A Wetland A is located along the western boundary of the property. This ' wetland is an isolated depression along the fenceline that defines the edge of the Peterson site with an adjacent farm field. Past farming activities have elevated sediment and nutrient levels accumulating within ' the wetland. This wetland is predominantly a reed canary grass monotype with annual weed species located at the transition between the reed canary grass monotype and cropped upland areas. Upland plant ' communities are comprised of soybeans and corn. Dominant wetland vegetation includes: reed canary grass (Phalaris arundinacea) with other species occurring as subdominants. The National Wetlands Inventory for ' Shakopee, Minnesota (Figure 4) maps this area as a ditched seasonally flooded palustrine emergent wetland (PEM1Cd). GES would classify this wetland as a ditched temporarily flooded palustrine emergent wetland ' (PEM1Ad) or as Circular 39 Type 2 inland fresh meadow. Soils were evaluated by digging soil pits perpendicular to the wetland ' edge and examining the profiles' texture, color, and redoximorphic characteristics. This wetland receives significant runoff from adjacent cropland and much of the soil profile was obscured by accumulated overwash sediments. Soils in Wetland A are described as 30 inches of dark brown (Munsell matrix color 10YR 3/1) silty loam with bright mottles (10YR 4/6) to 30 inches. The Carver County Soil Survey (Figure 6) map soils in the vicinity of Wetland A as Hamel soils (WM). The colors and textures of soils observed along basin transects are consistent with Hamel loams. Upland soil profiles exhibited mixed silt loams with dark brown ' matrix colors (10YR 3/2) for 6 inches over gray -brown loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny loams (KC2) on 6 to 12 percent slopes. ' Free water was present at the surface in sample points at the wetland center and were present within 8 inches of the soil surface at transitional soil pits. It is also important to note that the evaluation took place after rainfall events of over 5 inches had occurred ten days prior to the evaluation. The wetland hydrology parameter in this wetland was met by documenting one primary indicator (surface water) at the wetland center and by two secondary indicators (FAC neutral vegetation) and using professional judgment at the transition between wetland and upland. ' No free water or evidence of saturation were observed at upland locations. 1 Peterson Property Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 3 of 8 The jurisdictional boundary was established at the change in vegetation from predominantly hydrophytic herbaceous species to a plant community ' dominated by crops. Wetland B t Wetland B is located along the Bluff Creek floodplain and in minor topographic ravines that focus overland flow to lower elevations on the site. This wetland occupies the northeastern portion of the site. Upland ' areas adjacent this wetland are comprised of old field plant communities on slopes that face south and east and by croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: ' reed canary grass, American elm (Ulmus americana), spotted jewelweed (Impatiens capensis), and the presence of plant species that are often associated with disturbed ground such as sandbar willow (Salix exigua), ' black willow (Salix nigra), giant goldenrod (Solidago gigantea), and yellow foxtail (Setaria glauca). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) maps only the most northwestern corner of the site. ' GES would classify a larger area as a seasonally flooded palustrine emergent/forested wetland (PEM/FO1 C) or as Circular 39 Type 3/7 inland shallow marsh/wooded swamp. ' Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic t characteristics. Soils in Wetland B are described as 13 inches of dark brown (Munsell matrix color 10YR 3/2) silty loam followed by black (10YR 2/1) loams to 24 inches. The Carver County Soil Survey (Figure 5) map ' soils in the vicinity of Wetland B as Hamel loams (HIM) or Houghton and Muskego soils (MK). The colors and textures of soils observed along basin transects are consistent with a variant of Hamel soils. Upland soil profiles exhibited mixed sandy loams with dark brown matrix colors (10YR 3/2) for 6 inches over bright yellow clay loam (10YR 4/3). Upland soils are mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes. The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by pioneering grasses, forbs or crops. Wetland C ' Wetland C is located adjacent to Pioneer Trail on the southern portion of the site. It is also located at the base of significant slopes to the north. The natural outlet has been blocked by the construction of a driveway at ' the western edge of the wetland and has probably been made wetter by the construction of roads and driveways next to the wetland. The center of the wetland was entirely open water at the time of the delineation and 1 Peterson Property ' Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 4 of 8 twas characterized by concentric rings of annual hydrophytic vegetation at the wetland/upland transition. Upland areas adjacent this wetland are comprised of croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass, green ash (Fraxinus pennsylvanica), switch grass (Panicum virgatum), and the presence of plant species that are often associated with disturbed ground such as giant ragweed (Ambrosia trifida), black willow, Iamb's quarters (Chenopodium album), and water smartweed (Polygonum amphibium). t The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify a this area as a seasonally flooded palustrine emergent wetland (PEMC) or as ' Circular 39 Type 3 inland shallow marsh. Soils were evaluated by digging soil pits perpendicular to the wetland ' edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland C are described as 14 inches of dark brown (Munsell matrix color 10YR 2/1) silty loam followed by black (10YR ' 211) loams to 20 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland C as Glencoe clay foams (GL). The colors and textures of soils observed along basin transects are consistent with a ' variant of Hamel soils or of an accumulation of eroded sediments from surrounding uplands. Upland soil profiles exhibited mixed silty clay loams with dark brown matrix colors (10YR 4/3) for 12 inches over bright yellow ' clay loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes. This wetland is an isolated depression that appears to be reliant upon surface runoff to maintain wetland hydrology. The jurisdictional boundary was established at a rise in topography and a change in vegetation from ' predominantly hydrophytic herbaceous species to a plant community dominated by crops. ' Wetland D Wetland D is located adjacent to Pioneer Trail on the southern portion of the site. It is also located at the base of significant slopes to the north. A natural connection to Wetland C has been blocked by the construction of a driveway at the eastern edge of the wetland. Upland areas adjacent this wetland are comprised of croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass, switch grass, and the presence of plant species that are often associated with disturbed ground such as giant ragweed, Iamb's quarters, ' and cocklbur (Xanthium strumarium). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a temporarily flooded 1 Peterson Property ' Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 5 of 8 palustrine emergent wetland (PEMA) or as Circular 39 Type 2 inland fresh meadow. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland D are described as 6 inches of dark brown (Munsell matrix color 10YR 4/2) silty loam followed by black (10YR 2/1) clay loams to 20 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland D as Cordova -Webster complex (CW). The colors and textures of soils observed along basin transects are consistent with a variant of Hamel soils or of an accumulation of eroded sediments from surrounding uplands. Upland soil profiles exhibited clay loams with brown matrix colors (10YR 4/2) for 14 inches over gray -brown clay loam (10YR 4/1). Upland soils are mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes. This wetland is an isolated depression that appears to be reliant upon surface runoff to maintain wetland hydrology. The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by crops. Wetland E Wetland E is located along the Bluff Creek floodplain and in minor topographic ravines that focus overland flow to lower elevations on the site. This wetland occupies the eastern portion of the site. Upland areas adjacent this wetland are comprised of old field plant communities on slopes that face north and by croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass with subdominants including Joe-pye weed (Eupatorium maculatum), stinging nettle (Urtica dioica), redtop (Agrostis alba), and lady's thumb (Polygonum persicaria). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a temporarily flooded palustrine emergent wetland (PEMA) or as Circular 39 Type 2 inland fresh meadow.

Upland soils are mapped as Lester -Kilkenny soils (KC2) on 6 to 12 percent slopes. i The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by pioneering grasses, forbs or crops. Wetland F Wetland F is located along a tributary floodplain that flows to the Minnesota River and in minor topographic ravines that were created by down -cutting at drain tile outlets. This wetland occupies a small portion of the southwestern corner of the site. Upland areas adjacent this wetland are comprised of sugar maple forest on steep slopes on either side of the tributary. Dominant wetland vegetation is scarce within the bottom of the ravine but includes: duckweed (Lemna minor). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a seasonally flooded palustrine emergent wetland (PEM1 C) or as Circular 39 Type 3 inland fresh marsh. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland F are described as 32 inches of accumulated sediments that are dark brown (Munsell matrix color 10YR 3/1). The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland F as Lester -Kilkenny loams (KF). The colors and textures of soils observed along basin transects are consistent with a variant of Hamel soils. Upland soil profiles exhibited silt loams with dark brown matrix colors (10YR 3/2) for 5 inches followed by 18 inches of gray -brown clay loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny soils (KD2) on 12 to 18 percent slopes. The jurisdictional boundary was established at an abrupt rise in topography. Wetland G Wetland G is located along the Bluff Creek floodplain and is surrounded by high quality sugar maple forest at the southeastern portion of the site. Dominant wetland vegetation includes: reed canary grass and wood nettle (Laportea canadensis) with subdominants including eastern cottonwood (Populus deltoides), white snakeroot (Eupatorium rugosum), box elder (Acer negundo), and black willow.

Upland soils are mapped as Lester -Kilkenny soils (KD2) on 12 to 18 percent slopes. ' The jurisdictional boundary was established at an abrupt rise in topography. Regulatory Jurisdiction ' Minnesota DNR Protected Waters The Minnesota DNR Protected Waters Inventory (Figure 7) does not map any protected waters or wetlands on the site. ' Minnesota Wetland Conservation Act The jurisdictional wetlands that were identified on the subject parcel are subject to the Wetland Conservation Act Rules Chapter 8420. Federal Regulatory Jurisdiction ' The enclosed wetland delineation data forms indicated whether wetlands are isolated or not for purposes of U.S. Army Corps of Engineers jurisdiction under Section 404 of the Clean Water Act. This determination is made by GES in the field at the time of the delineation and is essentially our best guess based on the portion of the particular wetland we observe. In some cases, only a small portion of the wetland edge is evaluated. If no inlets or outlets are observed in the evaluated area, and none are evident on U.S.G.S. topographic maps or aerial photos, we are inclined to 1 Peterson Property ' Wetland Delineation Report GES Project No. 2005.133 December 6, 2005 Page 8 of 8 ' determine the wetland is isolated. However, since the entire wetland is sometimes not assessed, it is possible that inlets and/or outlets do exist ' and that the wetland has a surface connection to a federal "navigable" water and, thus, falls within the jurisdiction of Section 404. Therefore, a determination by GES of whether a particular wetland is isolated or not ' should not be considered a final determination with regard to Corps jurisdiction. t Concurrence with our findings should be obtained from the U.S. Army Corps of Engineers, Carver County, and the City of Chanhassen before any earthwork is undertaken on the site. Additional information regarding the vegetation, soils and hydrology of the wetlands are included in Appendix A. Ground photos of all the areas evaluated for jurisdictional criteria are included in Figures 7-10. The information contained herein represents my findings during wetland delineation activities conducted on October 14, 2005 at the referenced site. Graham Environmental Services, Inc.

Describe connection: This is the floodplain of a tributary that flows to the Minnesota River Memorandum TO: Lori Haak FROM: Scott Krych, Mike Graham — GES, Inc. DATE: December 30, 2005 SUBJECT: Wetland Delineation for D.R. Horton Project, Chanhassen, Minnesota As you know, Graham Environmental Services, Inc. (GES) conducted a delineation of wetlands at the above -referenced site (Figure 1) on October 15, 2005. We have provided your office with a copy of our delineation report. Subsequently, the City has indicated that they believe that a depressional area not delineated by GES (Figure 2), but delineated previously by Pinnacle Engineering and surveyed by RLK in 2001 (Figure 3), is jurisdictional wetland. The depressional area in question will be called "Area 1" throughout the remainder of this memorandum. Area 1 is located on the northern half of the site southeast of Wetland A, as identified in the GES report. This area occupies a depression that is tiled, ditched, and was planted in crops every year since 1985 according to Farm Service Agency (FSA) slides. Sloping cropland borders this depression on all sides. Area 1 is served by an 8-inch drain tile that was actively removing water from the area during our delineation activities. The drain tile outlet is located at the southwestern portion of the site in an area that was delineated as Wetland F. To further investigate Area 1, GES reviewed all available aerial photographs for the site at the Carver County FSA offices on December 15, 2005. Photographs were available for the years 1985-1994 and 2000. We also reviewed an aerial photograph for 2003 from another source as part of our analysis.' Carver County FSA aerial photographs flown annually during the months of June, July, or August were also evaluated to review the site for crop stress due to wetness, inclusion of non -cropped areas within cropland, different planting dates, surface water, areas drowned out by accumulated water, areas not planted due to moisture, etc.2 We've summarized our findings below. ' ' GES followed guidelines for reviewing FSA aerial photographs established in the August 1994 "State of Minnesota Interagency Cooperative Agreement for Implementation of the Federal Wetland Delineation Memorandum of Agreement"(MOA) between the Natural Resource Conservation Service, the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency, and the U.S. Fish and Wildlife Service. 2 GES followed the Off -Site Procedures Use of Rainfall Data with ASCS Slides to Determine Hydrology section of the MOA to evaluate the aerial photographs. These procedures require the use of rainfall spreadsheets from the NOAA weather station nearest to the site. This methodology is especially helpful in evaluating whether or not wetland hydrology exists in cropland areas that are planted or plowed. Ms. Lori Haak D.R. Horton Site December 30, 2005 Page 2 of 4 Hydrology Rainfall data is used to identify whether a specific area has received normal precipitation for an individual year or to establish climatic context for a specific region. Rainfall totals are a way to assess short-term fluctuations in ground and surface water levels that are important to note when evaluating wetland parameters. Areas that have received above normal rainfall may exhibit wetland hydrology when they would normally be dry. Conversely, areas that receive less than normal precipitation may not exhibit wetland hydrology when they normally would. The climatic context is a longer term evaluation of rainfall totals and may indicate growing season drought, pluvial, or normal periods and are also important to note when evaluating wetland parameters. Both rainfall and climactic data are important in areas that are farmed, tiled, ditched or that have numerous temporarily flooded wetlands. Both types of rainfall data are used when conducting on- and off -site evaluations on farmland. The Chaska recording station is the nearest station to the site providing rainfall data. The average annual precipitation for this area according to data from this station is 30.31 inches. Table 1 lists the average monthly rainfall for this area and the departure from normal during the four months prior to our site visit in October. Table 1 Month Average Monthly Rainfall (inches) 2005 Recorded Monthly Rainfall inches Departure from Normal (inches) June 4.16 7.26 +3.10 July 4.41 2.20 -2.21 August 4.34 4.73 +0.39 September 2.97 9.85 +6.88 October 2.14 5.01 1 +2.87 All data reported from Station 1465, Chaska, Minnesota. A plus (+) sign indicates above average amounts, a minus (-) sign indicates below average amounts. The climatic conditions for this area of the state were 125 percent of normal for the year through October, 110 percent of normal for the year through September, and 100 percent of normal for the year through August. For the southern one-half of Minnesota, the 2005 growing season ended on a very wet note. All-time high monthly rainfall records were set in some communities. For many locations in central and southern Minnesota, September precipitation totals topped seven inches. Rainfall in some locations exceeded ten inches for the month (Minnesota Climatology Working Group Home Page, October 2005). FSA aerial photographs show that there were secondary indicators of crop stress in Area 1 in the years 1993, 1994, and 2000. All three of these years were considered wetter than average or drier than average and would not be included in the analysis under MOA procedures. No signatures were present in years which fell within the Ms. Lori Haak D.R. Horton Site December 30. 2005 Page 3 of 4 normal precipitation range according to the MOA methodology. The MOA that prescribes how FSA reviews should be conducted requires a summary of the slide review and climate analysis. It also states "That if the number of wet signatures in normal years is > 50 percent, the site will be considered to have wetland hydrology." Since signatures meeting MOA criteria are present in only three of the available 12 years (25 percent), the wetland hydrology threshold described in the MOA was not met in Area 1. Vegetation The plant community in Area 1 is dominated by soybeans (Glycine max), pinkweed (Polygonum pensylvanicum, FACW+), barnyard grass (Echinochloa crusgalli, FACW) and cocklebur (Xanthium strumarium, FAC) (see attached data sheet for more ' comprehensive information). Although the vegetation meets wetland criteria per the 1987 Corps of Engineers Wetlands Delineation Manual (1987 Manual), it should be noted that these species are all annuals and reflect above -normal precipitation that was ' present in this area during critical germination periods during the 2005 growing season. Hydric Soils The soils in Area 1 exhibit up to 25 inches of accumulated sediments (eroded deposits) over the original soil surface. The accumulated sediments are dark brown (10YR 3/2) silt Ioams over dark gray/brown (10YR 4/2) silt loam. Soils exhibited bright (10YR 4/6) mottles to within six inches of the soil surface, but may be oxidation due to farming practices, crop residue, and some water level fluctuation. No inundation or saturation was observed within 16 inches of the soil surface for the soil profiles examined within ' the depression. Conclusion Based on the conditions outlined above and within our delineation report, Area 1 is considered an "atypical situation" as defined in the 1987 Manual due to the effects of human activities. This area exhibited a plant community that is dominated by annual ' weed species some of which are considered hydrophytic and others as upland species. Due to the orientation of the plant species identified in this area, the plant community is considered FAC neutral or hydrophytic. Hamel soils are transitional, occurring in ' sloping areas where shallow depressions or drainages occur on the landscape. These soils were generally created in areas where surface sediments accumulate due to surface runoff. Hamel soils meet the technical definition of hydric soils when there are no hydrologic modifications. However, the hydrology that formed these soils historically has been altered by the presence of drain tiles and a shallow surface drain. Area 1 did not exhibit any primary indicators of hydrology or the required two secondary indicators (only FAC neutral plant community was present) to be called jurisdictional wetland. It is noteworthy that other similar basins on the site exhibited primary wetland indicators after significant rainfall events in October and as defined by the 1987 Manual. In summary, it is our opinion that Area 1 is not technically a jurisdictional wetland. 1 Ms. Lori Haak D.R. Horton Site December 30, 2005 Page 4 of 4 Regardless, the developer has indicated a desire to acquiesce to calling a portion of Area 1 jurisdictional wetland and mitigating for the impacts if we can agree to its size. The most recent City correspondence included a hand -sketch of a suggested wetland boundary including approximately two acres. The Pinnacle Engineering delineation and RLK survey completed in 2001 identifies through technical methods a 0.26 acre wetland. Subsequently, this wetland boundary was included on the recently approved concept plan on the property. If the City concurs with the 0.26 acre boundary as the jurisdictional wetland of Area 1, we are prepared to submit a Wetland Replacement Plan (WRP) on behalf of the developer, which includes 2:1 mitigation per the Wetland Conservation Act (WCA) for the 0.26 acre area. The mitigation plan would include the possibility of on -site New Wetland Credit (NWC) as well as Public Value Credits on the site through the construction of storm water ponds. If NWC on the site proves infeasible, we would appreciate discussing with you the potential of restoring adequate wetland area within another area in the City. We are also in contact with Houston Engineering, who are working on a WRP for the wetland impact of the East-West Collector, regarding the possibility of a joint mitigation effort. We would appreciate an opportunity to discuss these issues with you after you have ' had a chance to review this memorandum. Thank you. Cc: Ron Mullenbach, D.R.

Box 189 Ellsworth, Wisconsin 54011 Wetland Delineation Report Peterson Site Prepared for: DR Horton Chanhassen, Minnesota December 8, 2005 Background Graham Environmental Services, Inc. (GES) has completed the site evaluation for jurisdictional wetlands on a parcel located in portions of the NW'/<, Section 26 and NE %of Section 27, T116N, R23W, Carver County, Minnesota. Pioneer Trail crosses the southern portion of the property and croplands, forested slopes, forested tributaries and individual farms border the west, north and eastern portions of the property (Figure 1). According to the U.S.G.S. Shakopee Quadrangle (Figure 2), elevations change significantly from the Bluff Creek floodplain and other tributaries to the highest elevations located at the center of the site. Seven wetlands are located throughout the site with cropland, old pasture, fencerows, wooded slopes and an abandoned home located on the upland areas. On October 14, 2005, GES evaluated the site for jurisdictional wetlands and found seven on the site. The approximate site and wetland boundaries are shown on a 2003 aerial photograph in Figure 3. Methodologies The site was assessed for wetlands using the on -site methods contained in the "Routine Determinations" section of the U.S. Army Corps of Engineers "Wetlands Delineation Manuar' (Technical Report Y-87-1, 1987). This is the methodology currently used by both the U.S. Army Corps of Engineers for implementation of Section 404 of the Clean Water Act and by local government units administering the Minnesota Wetland Conservation Act. GES classified the wetlands under the U.S. Fish and Wildlife Service (FWS) Cowardin system and Circular 39 methodologies.

This wetland is an isolated depression along the fenceline that defines the edge of the Peterson site with an adjacent farm field. Past farming activities have elevated sediment and nutrient levels accumulating within the wetland. This wetland is predominantly a reed canary grass monotype with annual weed species located at the transition between the reed canary grass monotype and cropped upland areas. Upland plant communities are comprised of soybeans and corn. Dominant wetland vegetation includes: reed canary grass (Phalaris arundinacea) with other species occurring as subdominants. The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) maps this area as a ditched seasonally flooded palustrine emergent wetland (PEM1Cd). GES would classify this wetland as a ditched temporarily flooded palustrine emergent wetland (PEM1Ad) or as Circular 39 Type 2 inland fresh meadow. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. This wetland receives significant runoff from adjacent cropland and much of the soil profile was obscured by accumulated overwash sediments. Soils in Wetland A are described as 30 inches of dark brown (Munsell matrix color 10YR 3/1) silty loam with bright mottles (10YR 4/6) to 30 inches. The Carver County Soil Survey (Figure 6) map soils in the vicinity of Wetland A as Hamel soils (WM). The colors and textures of soils observed along basin transects are consistent with Hamel loams. Upland soil profiles exhibited mixed silt loams with dark brown matrix colors (10YR 3/2) for 6 inches over gray -brown loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny loams (KC2) on 6 to 12 percent slopes. Free water was present at the surface in sample points at the wetland center and were present within 8 inches of the soil surface at transitional soil pits. It is also important to note that the evaluation took place after rainfall events of over 5 inches had occurred ten days prior to the evaluation. The wetland hydrology parameter in this wetland was met by documenting one primary indicator (surface water) at the wetland center and by two secondary indicators (FAC neutral vegetation) and using professional judgment at the transition between wetland and upland. No free water or evidence of saturation were observed at upland locations. t Peterson Property Wetland Delineation Report GES Project No. 2005.133 ' December 8, 2005 Page 3 of 8 The jurisdictional boundary was established at the change in vegetation ' from predominantly hydrophytic herbaceous species to a plant community dominated by crops. ' Wetland B Wetland B is located along the Bluff Creek floodplain and in minor topographic ravines that focus overland flow to lower elevations on the site. This wetland occupies the northeastern portion of the site. Upland areas adjacent this wetland are comprised of old field plant communities on slopes that face south and east and by croplands planted to corn ' during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass, American elm (Ulmus americana), spotted jewelweed (Impatiens capensis), and the presence of plant species that are often associated with disturbed ground such as sandbar willow (Salix exigua), black willow (Salix nigra), giant goldenrod (Solidago gigantea), and yellow foxtail (Setaria glauca). The National Wetlands Inventory for Shakopee, t Minnesota (Figure 4) maps only the most northwestern corner of the site. GES would classify a larger area as a seasonally flooded palustrine emergent/forested wetland (PEM/F01 C) or as Circular 39 Type 3/7 inland ' shallow marsh/wooded swamp. Soils were evaluated by digging soil pits perpendicular to the wetland ' edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland B are described as 13 inches of dark brown (Munsell matrix color 10YR 3/2) silty loam followed by black (10YR ' 2/1) loams to 24 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland B as Hamel loams (HM) or Houghton and Muskego soils (MK). The colors and textures of soils observed along ' basin transects are consistent with a variant of Hamel soils. Upland soil profiles exhibited mixed sandy loams with dark brown matrix colors (10YR 3/2) for 6 inches over bright yellow clay loam (10YR 4/3). Upland soils are mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes. ' The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species ' to a plant community dominated by pioneering grasses, (orbs or crops. Wetland C ' Wetland C is located adjacent to Pioneer Trail on the southern portion of the site. It is also located at the base of significant slopes to the north. The natural outlet has been blocked by the construction of a driveway at ' the western edge of the wetland and has probably been made wetter by the construction of roads and driveways next to the wetland. The center of the wetland was entirely open water at the time of the delineation and ' Peterson Property Wetland Delineation Report GES Project No. 2005.133 t December 8, 2005 Page 4 of 8 was characterized by concentric rings of annual hydrophytic vegetation at ' the wetland/upland transition. Upland areas adjacent this wetland are comprised of croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass, green ash ' (Fraxinus pennsylvanica), switch grass (Panicum virgatum), and the presence of plant species that are often associated with disturbed ground such as giant ragweed (Ambrosia trifida), black willow, Iamb's quarters ' (Chenopodium album), and water smartweed (Polygonum amphibium). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify a this ' area as a seasonally flooded palustrine emergent wetland (PEMC) or as Circular 39 Type 3 inland shallow marsh. ' Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland C are described as 14 inches of dark ' brown (Munsell matrix color 10YR 2/1) silty loam followed by black (10YR 2/1) loams to 20 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland C as Glencoe clay loams (GL). The colors ' and textures of soils observed along basin transects are consistent with a variant of Hamel soils or of an accumulation of eroded sediments from surrounding uplands. Upland soil profiles exhibited mixed silty clay loams with dark brown matrix colors (10YR 4/3) for 12 inches over bright yellow clay loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes. ' This wetland is an isolated depression that appears to be reliant upon surface runoff to maintain wetland hydrology. The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by crops. ' Wetland D Wetland D is located adjacent to Pioneer Trail on the southern portion of the site. It is also located at the base of significant slopes to the north. A ' natural connection to Wetland C has been blocked by the construction of a driveway at the eastern edge of the wetland. Upland areas adjacent this wetland are comprised of croplands planted to corn during the 2005 ' growing season. Dominant wetland vegetation includes: reed canary grass, switch grass, and the presence of plant species that are often associated with disturbed ground such as giant ragweed, Iamb's quarters, ' and cocklbur (Xanthium strumarium). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a temporarily flooded Peterson Property Wetland Delineation Report GES Project No. 2005.133 December 8, 2005 Page 5 of 8 palustrine emergent wetland (PEMA) or as Circular 39 Type 2 inland fresh meadow. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland D are described as 6 inches of dark brown (Munsell matrix color 10YR 4/2) silty loam followed by black (10YR 2/1) clay loams to 20 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland D as Cordova -Webster complex (CW). The colors and textures of soils observed along basin transects are consistent with a variant of Hamel soils or of an accumulation of eroded sediments from surrounding uplands. Upland soil profiles exhibited clay loams with brown matrix colors (10YR 4/2) for 14 inches over gray -brown clay loam (10YR 4/1). Upland soils are mapped as Lester -Kilkenny soils (KE2) on 18 to 25 percent slopes. This wetland is an isolated depression that appears to be reliant upon surface runoff to maintain wetland hydrology. The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species to a plant community dominated by crops. Wetland E Wetland E is located along the Bluff Creek floodplain and in minor topographic ravines that focus overland flow to lower elevations on the site. This wetland occupies the eastern portion of the site. Upland areas adjacent this wetland are comprised of old field plant communities on slopes that face north and by croplands planted to corn during the 2005 growing season. Dominant wetland vegetation includes: reed canary grass with subdominants including Joe-pye weed (Eupatorium maculatum), stinging nettle (Urtica dioica), redtop (Agrostis alba), and lady's thumb (Polygonum persicaria). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a temporarily flooded palustrine emergent wetland (PEMA) or as Circular 39 Type 2 inland fresh meadow. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland E are described as 14 inches of dark brown (Munsell matrix color 10YR 3/1) silty loam followed by dark brown (10YR 3/1) loams to 30 inches. The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland E as Klossner muck (PM) or Hamel soils (HM). The colors and textures of soils observed along basin Peterson Property Wetland Delineation Report GES Project No. 2005.133 ' December 8, 2005 Page 6 of 8 transects are consistent with a variant of Hamel soils. Upland soil profiles ' exhibited mixed silt loams with dark brown matrix colors (10YR 3/1) for 34 inches. Upland soils are mapped as Lester -Kilkenny soils (KC2) on 6 to 12 percent slopes. ' The jurisdictional boundary was established at a rise in topography and a change in vegetation from predominantly hydrophytic herbaceous species ' to a plant community dominated by pioneering grasses, forbs or crops. Wetland F ' Wetland F is located along a tributary floodplain that flows to the Minnesota River and in minor topographic ravines that were created by down -cutting at drain tile outlets. This wetland occupies a small portion of ' the southwestern corner of the site. Upland areas adjacent this wetland are comprised of sugar maple forest on steep slopes on either side of the tributary. Dominant wetland vegetation is scarce within the bottom of the ravine but includes: duckweed (Lemna minor). The National Wetlands Inventory for Shakopee, Minnesota (Figure 4) does not map any wetlands on this portion of the site. GES would classify this area as a seasonally ' flooded palustrine emergent wetland (PEM1C) or as Circular 39 Type 3 inland fresh marsh. ' Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland F are described as 32 inches of ' accumulated sediments that are dark brown (Munsell matrix color 10YR 3/1). The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland F as Lester -Kilkenny loams (KF). The colors and textures of soils ' observed along basin transects are consistent with a variant of Hamel soils. Upland soil profiles exhibited silt loams with dark brown matrix colors (10YR 3/2) for 5 inches followed by 18 inches of gray -brown clay loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny soils (KD2) ' on 12 to 18 percent slopes. The jurisdictional boundary was established at an abrupt rise in topography. Wetland G ' Wetland G is located along the Bluff Creek floodplain and is surrounded by high quality sugar maple forest at the southeastern portion of the site. Dominant wetland vegetation includes: reed canary grass and wood nettle ' (Laportea canadensis) with subdominants including eastern cottonwood (Populus deltoides), white snakeroot (Eupatorium rugosum), box elder (Acernegundo), and black willow. The National Wetlands Inventory for Peterson Property Wetland Delineation Report GES Project No. 2005.133 December 8, 2005 Page 7 of 8 Shakopee, Minnesota (Figure 4) does not map any wetlands on this ' portion of the site. GES would classify this area as a seasonally flooded palustrine emergent wetland (PEM1C) or as Circular 39 Type 3 inland fresh marsh. Soils were evaluated by digging soil pits perpendicular to the wetland edge and examining the profiles' texture, color, and redoximorphic characteristics. Soils in Wetland G are described as 12 inches of accumulated sediments that are dark brown (Munsell matrix color 10YR 4/1) followed by 8 inches of black loam (N3/0). The Carver County Soil Survey (Figure 5) map soils in the vicinity of Wetland G as Lester - Kilkenny loams (KF). The colors and textures of soils observed along basin transects are consistent with floodplain soils in depositional areas of riverine systems. Upland soil profiles exhibited silt loams with dark brown matrix colors (10YR 3/2) for 5 inches followed by 18 inches of gray -brown clay loam (10YR 4/2). Upland soils are mapped as Lester -Kilkenny soils (KD2) on 12 to 18 percent slopes. The jurisdictional boundary was established at an abrupt rise in topography. Regulatory Jurisdiction Minnesota DNR Protected Waters The Minnesota DNR Protected Waters Inventory (Figure 7) does not map any protected waters or wetlands on the site. Minnesota Wetland Conservation Act The jurisdictional wetlands that were identified on the subject parcel are subject to the Wetland Conservation Act Rules Chapter 8420. Federal Regulatory Jurisdiction The enclosed wetland delineation data forms indicated whether wetlands are isolated or not for purposes of U.S. Army Corps of Engineers jurisdiction under Section 404 of the Clean Water Act. This determination is made by GES in the field at the time of the delineation and is essentially our best guess based on the portion of the particular wetland we observe. In some cases, only a small portion of the wetland edge is evaluated. If no inlets or outlets are observed in the evaluated area, and none are evident on U.S.G.S. topographic maps or aerial photos, we are inclined to t Peterson Property Wetland Delineation Report GES Project No. 2005.133 ' December 8, 2005 Page 8 of 8 determine the wetland is isolated. However, since the entire wetland is ' sometimes not assessed, it is possible that inlets and/or outlets do exist and that the wetland has a surface connection to a federal "navigable' water and, thus, falls within the jurisdiction of Section 404. Therefore, a ' determination by GES of whether a particular wetland is isolated or not should not be considered a final determination with regard to Corps jurisdiction. ' Concurrence with our findings should be obtained from the U.S. Army Corps of Engineers, Carver County, and the City of Chanhassen before ' any earthwork is undertaken on the site. Additional information regarding the vegetation, soils and hydrology of the ' wetlands are included in Appendix A. Ground photos of all the areas evaluated for jurisdictional criteria are included in Figures 7-10.
