Replacement Plan Albert Villas Development Albertville, Minnesota 1.0 INTRODUCTION Edina Development (Edina) is proposing this replacement plan as a means of complying with a Restoration Order issued February 23, 2005. The Restoration Order was issued for non-compliance to the Wetland Conservation Act (WCA) permits issued for multiple phases of the Albert Villas residential development project. The Albert Villas Development is located within Sections 2 and 11/ Township 120N, Range 23W in Albertville, Wright County, Minnesota (Site), as depicted on Figure 1. The local governmental unit (LGU) is the City of Albertville, and their consultant Short Elliot and Hendrickson (SEH) provides technical assistance for the wetland and engineering Issues. The Restoration Order identified the following concerns with Phases 1 and 2: 0> mitigation areas 1m through 5m (Figure 2) do not meet the requirements of the approved replacement plan. 0> Deed Restrictions and Covenants for the replacement wetlands are not on file with Wright County. · additional fill was placed in a wetland area between fill areas 7f and Bf (Figure 3). The Restoration Order identified the following concerns for Phases 3, 4, and 6: · A 3D-foot buffer strip was to be placed along the borders of the existing wetlands and mitigation areas. · Signage would be placed along the buffer strip. · All wetlands and mitigation area would be placed under a Conservation Easement on the property deeds. The Restoration Order offered two options as a resolution. Option A proposed completing the replacement plans as they were proposed in each of the wetland permit applications for the different phases of the project. Option B offered the submission of a replacement plan that proposes to modify the original replacement plans if any of the requirements of the Restoration Order can not be completed. Edina has chosen Option B, due to the legalities concerning covenants and restriction requirements of the original replacement plan. In order to better Pinnacle Engineering, Inc. Project Number MN00039.04 10f7 Replacement Plan Albert Villas Restoration Order .. . r I I 1 i i t [ [ understand why the Restoration Order was ordered, Edina offers the following as a brief explanation of the complexity of this issue. 2.0 BACKGROUND One of the conditions of the WCA permit was to submit to the County recorder restrictions and easements on the property concerning the wetland mitigation areas as well as the existing wetlands. In early 2000, Edina submitted, what they believed to be, all documentation concerning property restrictions and easements to the City and the City's consultants for review. The review was completed, and Edina was given a Developers Agreement. The SEH office responsible for engineering aspects of the Albert Villas project is located in St. Cloud, Minnesota, and the SEH office responsible for wetland issues is located in Vadnais Heights, Minnesota. Even though Albertville retained a qualified consultant, it appears the two SEH offices did not communicate with each other or with the City of Albertville in regards to the wetland conservation easement. As a result, the conservation easement, which Edina believed had placed on the wetlands or mitigation areas, was not recorded on the properties. A utility easement is currently recorded on the properties, and a Developer's Agreement indicating that all easements had been placed on the properties was issued by the LGU to Edina. As the phases of the project progressed over the next three years the properties were sold to individual home-owners. Edina no longer retained access rights to the properties. The confusion concerning the conservation easement continued as the monitoring reports for Phases 1 and 2 were sent to the SEH office in Vadnais Heights and Edina. SEH in Vadnais Heights would inquire about the conservation easements, and SEH in St. Cloud would respond that all of the easements were in place per the Developer's Agreements with the LGU. The monitoring reports documented and recommended actions to be taken in order to achieve successful mitigation areas. In addition, mitigation areas began to be impacted by home owner's activities and individual builders as they regraded the lots for home construction. Currently, Edina is being asked to place Covenants and Restrictions on property they no longer own or have rights to. 3.0 EXISTING CONDITIONS The following is a discussion of the status of each of the wetland mitigation areas permitted for the Albert Villas development. The discussion is followed by a brief summary . Pinnacle Engineering, Inc. Project Number MN00039.04 20f7 Replacement Plan Albert Villas Restoration Order l I I i { ~ . 3.1 Phase 1 and 2 Mitigation Area 1M Mitigation Area 1M is located south of Kahl Avenue, north of 52nd Street, west of Jason A venue, in the northern portion of Albert Villas. This area is adjacent to the south of an existing wetland and adjacent to the east of storm water detention pond #2. Stormwater pond #2 is located adjacent to 1M. The viability of the existing wetland adjacent to the north would suggest that the stormwater pond is not affecting the wetland or the mitigation area hydrology. 1M was proposed to be 0.35-acre in size. This mitigation area currently does not meet the wetland criteria (Figure 4). Mitigation Area 2M Mitigation area 2M is located south of 52nd Street along the northern periphery of a large wetland that forms the heart of the development. Mitigation area 2M was excavated down an additional 6-12 inches to ensure sufficient wetland hydrology and seeded with a wet meadow seed mixture (BWSR W2 or similar). 2M was proposed to be 0.39-acre is size (Figure 5). Mitigation Area 3M Mitigation area 3M is located south of 52nd Street, northwest of 51st Court, along the northeast periphery of the large central wetland. Mitigation area 3M was regraded, the Kentucky blue grass (Faa pratensis) removed, and seeded with a wet meadow seed mixture (BWSR W2 or similar). 3M was proposed to be 0.21-acre in size (Figure 6). Mitigation Area 4M Mitigation area 4M is located southwest of 51st Court along the eastern boundary of the large central wetland. Mitigation area 4M was excavated down an additional 6-12 inches to ensure sufficient wetland hydrology and seeded with a wet meadow seed mixture (BWSR W2 or similar). 4M was proposed to be O.l1-acre is size (Figure 7). Mitigation Area 5M Mitigation area 5M is located south of 51st Court along the north side of the large existing wetland. This area is adjacent to the east of an existing wetland and adjacent to the west of stormwater detention pond #4. Stormwater pond #4 is located adjacent to 5M but separated by an approximately 3D-foot upland buffer. A hydrologic study of the existing wetlands association with the stormwater pond has continued as part of the ongoing monitoring. The results indicate that the stormwater pond has little or no influence on the existing wetland or mitigation area 5M. 5M was proposed to be 0.08- acre in size. Pinnacle Engineering, Inc. Project Number MNOO039.04 3of7 Replacement Plan Albert Villas Restoration Order f i f I I 1 [ 1 l [ ( L t oJ . WetIand area between 7f and Sf This area is located south of 51st Court along the north side of the existing Stormwater pond #4. This wetland area was protected from mass grading by means of a silt fence. However, currently the area does not meet the criteria for a wetland. Homebuilders or home owners may have filled this area or the hydrology may not be enough to maintain wetland vegetation. The size of this wetland area is 0.09 acre. 3.2 Phase 3, 4 and 6 3D-foot buffer area The 30-foot buffer area surrounding the wetlands and mitigation areas is not present in Phase 3/ 4, and 6. Home owners have disturbed the buffer strip area up to the edge of the wetlands and mitigation areas. 4.0 REPLACEMENT PLAN Components of the replacement plan include Covenants and Restrictions for the wetland and mitigation areas on property not owned by Edina, signage monument wording, placement and locations, and restoration of the mitigation areas. 4.1 Conservation Easements Several home owners have stated that placing the deed restrictions and covenants on property not owned by Edina will lead to legal proceedings between Edina, the LGU and the individual homeowners. This process will require Edina and the City to expend a considerable amount of time, effort and money and may not result in the mitigation areas being constructed, restored, or replaced. Even after the lengthy process, it is unknown if this process would provide the legal means to meet requirements of the wetland permits. This is the reason that Option A of the restoration Order cannot be met in a timely manner. As part of Option B, Edina will pursue replacement of the contested mitigation areas by means of constructing new wetlands in the undeveloped area adjacent to Phase 6 of the Albert Villas development, as allowed in the Restoration Order. Edina will provide the covenants and easements using the Board of Water and Soil Resources form for the proposed new mitigation areas (Appendix A). 4.2 Signage Clear signage designating the areas of the wetlands and mitigation areas will be placed at the edge of the wetlands and mitigation areas on alternate lot lines. The signage will state, "This area is a protected wetland mitigation area. No mowing or disturbance Pinnacle Engineering, Inc. Project Number MN00039.04 4of7 Replacement Plan Albert Villas Restoration Order " . l l [ l ! ! L Gf5 . ? toe",- &<>n . beyond this point. Please report any disturbances to the City of Albertville." The signage will be placed on 4X4 wood monuments (Appendix B). l _ -? 4.3 Mitigation areas {)((lIJh(. n( (. . Mitigation Area 1M On going discussions with the property owners of lots 6 and 7 of Block 1, Phase II indicated that they will not permit restoration activities on their properties. This reduces the 0.35-acre mitigation area to 0.20 acre. The revised 1M will be scraped or excavated down an additional 12-24 inches to ensure sufficient wetland hydrology and seeded with a wet meadow seed mixture (BWSR W2 or similar). Additional wetland vegetation from the adjacent wetland should establish itself in the re-graded mitigation area. 1M will be surveyed to confirm that the excavation and size meet the specified size and depth. The remaining 0.15 acre of mitigation area will be replaced by means of constructing replacement wetlands to the east of County Ditch Number 9, east of the impacted wetland area. The mitigation will meet the 4:1 replacement wetland to unsuccessful mitigation wetland ratio required by the Restoration Order 9 (Figure 8). Mitigation Area 2M Mitigation area 2M will be surveyed to confirm that the excavation and size meet the specified size and depth. The mitigation area will also be reseeded and mulched with a wet meadow seed mixture (BWSR W2 or similar). Mitigation Area 3M Mitigation area 3M will be surveyed to confirm that the excavation and size meet the specified size and depth. The mitigation area will also be reseeded and mulched with a wet meadow seed mixture (BWSR W2 or similar). Mitigation Area 4M Mitigation area 4M will be surveyed to confirm that the excavation and size meet the specified size and depth. The mitigation area will also be reseeded and mulched with a wet meadow seed mixture (BWSR W2 or similar). Mitigation Area 5M On going discussions with the property owners of Lot 58 of Block 7, Phase II indicated that they will not permit restoration activities on the property. The entire 0.08 acre of mitigation area will be replaced by means of constructing replacement wetlands to the east of County Ditch Number 9, east of the impacted wetland area. The mitigation will meet the 4:1 replacement wetland to unsuccessful mitigation wetland ratio required by the Restoration Order. Pinnacle Engineering, Inc. Project Number MNOO039.04 50f7 Replacement Plan Albert Villas Restoration Order [ [ f I [ l L J' . Wetland area between 7f and Sf This wetland area of 0.09 acre will be replaced in another location. The remaining 0.15 acre of mitigation area will be replaced by means of constructing replacement wetlands to the east of County Ditch Number 9, east of the impacted wetland area. Edina proposes a 2:1 replacement wetland to impacted wetland ratio. 4.4 Wetland Construction Wetland mitigation areas totaling 0.23 acre will be replaced at a 4:1 replacement ratio, as stated in the Replacement Order. The total amount of replacement mitigation area will total 0.92 acre. The wetland replacement for the wetland area between 7f and 8f is 0.09 acre in size and will be mitigated at a 2:1 ratio. This means that 0.09 acre of new wetland credit and 0.09 acre of public value credit will be used at the replacement and mitigation areas to the east of the wetland area between 7f and 8f. The total area of constructed wetland must be greater than 1.01 acre in order to meet the requirements of the Restoration Order. In addition, there will need to be a buffer of greater than 0.09 acre around the newly constructed wetland for the 0.09 acre of public value credit needed. The replacement mitigation areas will be placed in out lots (Figure 9). The newly constructed wetland will total 1.07 acre in size. This meets the 4:1 ratio for the replacement mitigation areas of 1M and 5M and the 1:1 portion of New Wetland Credit (NWC) of the wetland area between 7f and 8f. The Public Value Credit (PVC) portion of the area between 7f and 8f will be part of the upland buffers adjacent the replacement mitigation areas. The upland buffers total 0.57 acre. Replacement Area A is 0.26 acre in size and located near Swamp Lake north of 49th Court/7th addition. A 25-foot, upland buffer is proposed to surround this wetland mitigation area. Replacement area B is 0.63 acre in size and located between County Ditch No. 9 and proposed lots along the western portion/7th addition and south of 51st Street. A 25-foot, upland buffer is proposed between the lots and this wetland mitigation area. Replacement area C is 0.18 acre in size and is located along County Ditch No.9, a stormwater pond, and Lots 3 and 4, Block 1, 6th Addition. A 25-foot upland buffer is proposed between the lots and this wetland mitigation area. The newly constructed wetlands will be constructed by excavating three irregular shaped basins to four feet below the existing ground level. The excavation will gradually slope up with the side slope ratio of, at maximum, 10:1 to meet the existing elevations. The excavated area will be backfilled with approximately one foot of organic topsoil and compacted, leaving a gently undulating bottom. The replacement mitigation wetland and replacement wetland will then be seeded with an appropriate wet meadow seed mix (BWSR seed mix W2 or similar) and will be scheduled to follow the MNDOT recommended seeding maintenance procedures (MNDOT 2571). Native Pinnacle Engineering, Inc. Project Number MNOOO39.04 6of7 Replacement Plan Albert Villas Restoration Order f , l r 1 l [ { [ ~ t' cattails and rushes from the Swamp Lake may establish themselves In any type 3 wetland areas. Creation of the replacement mitigation wetlands will involve excavation using backhoes and other small equipment. Best management practices, such as silt fence, hay bales, and mulch will be in place until native ground cover establishes itself. Hydrology to the replacement mitigation wetland areas A and B will be supplied by the outlet of Swamp Lake. The current outlet is piped from Swamp Lake to County Ditch No.9. The proposed route will direct water to the replacement mitigation area, then to a stormwater pond, which will outlet into replacement area B and County Ditch No.9. Replacement Area C will receive hydrology from overland flow from the surrounding watershed and outlet to County Ditch No.9. Soils in all of the replacement mitigation areas consist of Cordova soils as reviewed in the Wright County Soil Survey. Cordova soils are less well drained, black to dark brown, sandy, clayey loam soils that are listed in the State and Federal soils list as hydric soils. 4.5 Monitoring The monitoring of the wetland replacement area will occur in accordance with parts 8420.610 and 8420.620 of WCA for up to five years to ensure the success of the created wetlands. Monitoring will include: · Visiting the mitigation area during the spring, summer, and fall of the first year. · Determining hydrology of the soils at the fixed photograph locations during each site visit. · Documenting dominant vegetation that exceeds 20% layer coverage. · Documenting the mitigation area with color photographs from fixed photograph locations. · Visiting the mitigation area during the growing season for the following years. · Preparing annual reports to the LGU describing the progress of the mitigation area and, if necessary, any changes to the mitigation plan. · Discussing success of mitigation plan with LGU. Annual reports will be presented to the LGU discussing the success of the mitigation. Monitoring procedures and reports will follow requirements stated in the WCA rules 8420.610 and 8420.620. Monitoring reports will be sent to the LGU or their representative by December 15 each year during the monitoring period. If the mitigation areas have established themselves within the five-year period, Edina may request a TEP review of the replacement mitigation areas to determine if any remaining monitoring will be required.

[ L L Proposed Monument The proposed monuments will be constructed from 4X4 wood posts with a placard on the top. The placard will state whether the area is a mitigation area or wetland area, no disturbance beyond that point, and to call the City of Albertville is disturbed. The placard should resemble the figure below. This area is a protected wetlandjntitigation area. *' 1 @ 1 Please report any disturbances to the City of Albertville. The 4X4 wood sign posts will be approximately 5 feet in length. They will be placed approximately 2 feet below the surface and 3 feet above the surface. The top will be trimmed to a 450 angle with the angled face facing the homeowner's property. The Signs will be placed on alternate lot lines at the wetland or mitigation area edge facing the homeowner's property. SEEDING AND PLANTING PLAN Albert Villas Development Albertville, Minnesota The Local Governmental Unit (LGU) for the project is the City of Albertville. Edina Development is proposing construction of a three replacement mitigation basins as replacement for the unsuccessful mitigation areas and additional wetland impacts. The goal of the mitigation is to provide a high quality Type 2, 3 wetlands. The current vegetation of the existing wetlands mainly consists of invasive, exotic reed canary grass (Phalaris arundinacea). The replacement will be accomplished through the creation of 1.07 acres of new wetland credit (NWC) and 0.57 acres of associated public value credit (PVC) comprised of upland buffers. Creation of the mitigated wetlands will involve excavation using backhoes and other small and heavy equipment. Best management practices, such as silt fence, hay bales, and mulch will be in place until native ground cover establishes itself. I Site Preparation The newly constructed wetlands will be constructed by excavating three irregular shaped basins to four feet below the existing ground level. The excavation will gradually slope up with the side slope ratio of, at maximum, a 10:1 to meet the existing elevations. The excavated area will be backfilled with approximately 1 foot of organic topsoil and compacted, leaving a gently undulating bottom. The replacement mitigation wetland and replacement wetland will then be seeded with an appropriate wet meadow seed mix (BWSR seed mix W2 or similar) and will be scheduled to follow the MNDOT recommended seeding maintenance procedures (MNDOT 2571). Hydrology to the replacement mitigation wetland areas A and B will be supplied by the outlet of Swamp Lake. The proposed route will direct water to replacement mitigation area A, then to a stormwater pond, which will out let into replacement area B and then to County Ditch No.9. Replacement Area C will receive hydrology from overland flow from the surrounding watershed and outlet to County Ditch No.9. If any vegetation is noticed within the mitigation areas, it should receive backpack-sprayed herbicide treatment with an aquatically labeled glyphosate (Rodeo™ or equivalent) in order to control the invasive species. f I r ! { J I I l L l Seeding Plan Appropriate seed mixtures for the proposed Type 2 wetlands are listed in the Guidelines For Restoring & Managing Native Wetland Vegetation by MNDOT and BWSR (Guidelines). The applicant, by using the seeding and planting methods as recommended in the Guidelines and maintenance methods described below, is committed to assuring the success of a high quality Type 2 - PEMB, wet meadow. Below are excerpts from the Guidelines pertaining to the seeding of a type 2 4 wetland and the associated upland buffer. Wetland T e Shallow marshes (Type 3), deep marshes (Type 4), open water wetlands (Type 5) Mixture s W1, W2 or W3, appropriate upland mix (U1-U7). Seed mixes are used in emergent, saturated, moist and upland zones.

Plant u land mix where soils are ex ected to be d . R1 is planted along the lower streambank and in floodplain areas. The upland mix is planted going up the slo es. Notes On Where & How To Use Seed Mixes: W1 - Contains all OBl species. which grow in the emergent aquatic (shallow marsh) zone. It can be used state-wide. This zone can also be planted with live plants and/or pre-vegetated mats (PVt.I1). The W1 mix was developed for use on projects that are too large for planting of live plants to be economically feasible. W2 - Contains sedge meadow & wet meadow species which grow in the saturated & moist soil (sedgelwet meadow) zone. It can be used state-wide. W3 - Contains wet prairie species which grow in the saturated & moist soil (sedgelwet meadow) zone of prairie pot-holes. It is for use in the prairie grassland area of the state. W4 -Is for swales and wet ditches. W5 - For same areas as W2. Mix was developed for BWSR cost share projects. It contains fewer species and is cheaper. W6 - For same areas as W3. Mix was developed for BWSR cost share projects. It contains fewer species and is cheaper. R1 - For streambank and floodplain restorations. See notes in mix tabulations. U1-U6 - Prairie mixes. See notes in seed mix tabulations for where to use them. U7 - Contains woodland edge/savanna species. For use in forested regions of the state. US - Contains mesic prairie species. Mix was developed for BWSR cost share projects. It contains fewer species and is cheaper. U9 - Contains dry prairie species. Mix was developed for BWSR cost share projects. It contains fewer species and is cheaper. U10 - BWSR cost share mix. For use on berms. U11 - BWSR cost share mix. For use in grassed swales. f I I I 1 { I L l Construction of the mitigation basins at elevations of the existing wetlands and the surficial runoff from the storm water treatment systems should adequately hydrate the soils. The area may need to be dewatered while construction activities are being conducted. The area will then be seeded with a W2 seed mixture, as suggested in the Guidelines. The seed mixture will be broadcast spread or have pre-vegetated mats placed in wet areas, the combination covering the entire area. The area will then be mulched using the type and method for mulching as recommended in the MnjDOT Seeding Manual 2000.

This is critical in the first three to five years and should be recognized as integral to the wetland mitigation success. Management will include both eliminating non-native and invasive vegetation along with creating ideal conditions for native plants to flourish. Some invasive plants are strong competitors and without management, could hamper establishment of the native planting. Invasive wetland species such as purple loosestrife, reed canary grass, and cattail exist in many urban wetlands, and may contribute seed to the restored area. Invasive species such as common buckthorn, yellow and white sweet clover, spotted knap-weed, and Canada thistle are of concern in upland areas. 1) Mowing During the first two years of plant establishment mowing at a height of 6 to 10 inches where feasible, during the growing season, will reduce competition from annual weeds. Mowing allows light to reach the small native seedlings and reduces competition from weeds for water and soil nutrients. 2) Spot application of herbicide Individual invasive plants (including cattail) can be eradicated through wick application or spraying of herbicide. Rodeo or other Minnesota Department of Natural Resources herbicides approved for use near / in water bodies should be applied by a licensed applicator at the appropriate times to control individual plants. 3) Eradicate large infestations with herbicide The most effective method of eradicating large colonies of plants is to wick-apply or spray them with herbicide. Use Rodeo when spray may come in contact with water and Roundup.in upland situations. Repeated application will probably be necessary. Apply to green, actively growing foliage. Herbicides can effectively control herbaceous non-native vegetation when applied in spring or fall. Take great care not to apply herbicide to surrounding native plants. A very small amount of herbicide can kill a plant. 4) Cut woody stems and apply herbicide to wound All undesirable woody plants, greater than 1/4-inch in diameter, which cannot be hand-pulled should be cut down to expose the vascular tissue, or cambium. Herbicide painted on the cambium will be transported within the plant, eventually killing it. Cut the woody plant at a height that ensures the native herbaceous plants will not have contact with the stump and herbicide. This procedure should not be conducted while woody plants are dormant. Vegetation Maintenance Schedule 1) Year 1 After planting, annual weeds should be mowed (before seed set) to a height of six to ten inches or removed as needed. The site will likely require one to two mowings. Spot herbicide application, or hand removal, of aggressive weeds such as reed canary grass and thistle should also occur when the management crew is at the site to mow. Also, at the beginning of the maintenance period any undesirable shrubs in the mitigation areas should be sprayed with an appropriate herbicide. July (middle) - Mow wetland (where feasible) at a height of six to ten inches. Spot spray aggressive invasive and non-native species. September (early)- Mow wetland at a height of six to ten inches, spot spray invasive species. Buckthorn is best treated with herbicide in the fall when the plants are storing energy. Buckthorns lose their leaves later in the season than native woody plants, which allows for easier buckthorn identification and herbicide treatment in late September through early November. [ I I t 2) Year 2 Conduct an initial site visit in May to evaluate status of restoration and determine management tasks for the year. These will likely include: Spring - Conduct burn approximately every third year starting the second or third year. May - Spot spray invasive species. Mow wetland at a height of six to ten inches (mowing may not be needed or may not be possible depending on wetness and condition). Re-seed areas that do not meet the performance standards. July - Mow prairie at a height of six to ten inches, spot spray invasive species. September - Spot spray invasive species. 3) Year 3 Conduct an initial site visit in May with to evaluate status of restoration and determine management tasks for the year. These will likely include: Excerpt from the Mn/DOT Seeding Manual 2000, Cover/nurse Crops - Cover crops provide a quick short-term vegetative cover while the permanent native species are establishing. A cover crop reduces the soils erosion potential and moderates the native seedlings microclimate during establishment. Typical cover crops in Mn/DOT's native mixes include oats/winter wheat, annual rye grass and slender wheatgrass. Winter wheat is substituted for oats during fall plantings. The annual rye grass provides good cover in early spring but does not do well in late spring and summer. It also does well dormant seeded. ReGreen (a hybrid cross between slender wheat grass and winter wheat) listed in the 2000 Specification B-series mixtures is used instead of oats/winter wheat for temporary cover (ReGreen will persist for up to three years). Native species seeded in the fall perform very well, but it is critical that winter wheat (or ReGreen) and annual rye grass be used as specified in the mixes to ensure adequate vegetation establishment on erodible sites. One drawback Mn/DOT has observed to ReGreen that is that it does not perform very well in saturated soils, shaded areas, or when it is interseeded into dead sod. I I I [ NOTE: The new native seed mixtures (310 - 350) have a much higher cover crop rate as compared to the 2000 B- series mixtures. When comparing seeding rates, note that 85% of the new mixture rates as compared to approximately 50% of the 2000 B-series mixtures are comprised of cover crop species. Cover crop species are inexpensive. Temporary Erosion Control- It is recommended to protect a new seeding by covering it with mulch or an erosion control blanket. In general, slopes that are 1:3 (vertical: horizontal) and flatter should be mulched with a clean grain straw or native grass mulch and disc anchored following seeding. Mulching should attempt to achieve 90% coverage of the exposed soil surface. This generally requires about 2 tons per acre of straw mulch. It is also recommended to use a high quality weed free mulch such as MCIA Certified Weed Free mulch (see below for specification) or a native grass (prairie) mulch. On slopes that are steeper than 1:3 it is recommended that the seeding be covered with an erosion control blanket. Generally, straw blankets containing double netting (Straw 25) perform best with native plantings. If seeding is being done in a ditch or swale that will receive moderate water flows for periods of time, it is recommended that a straw/coconut blanket be used to cover it. Other more severe situations such as very steep slopes and/ or channels exposed to high water velocities will require more specialized treatments that are not covered in this manual. NOTE: Mulches derived from pasture hay containing reed canary grass, smooth brome and other introduced forage species may contain enough seed of those species to ruin your native grass and forb planting. They are not recommended for use with native plantings. Generic Specification Example: Mn/DOT Type 3 (MCIA Certified Weed Free Mulch) - This mulch shall consist of clean grain straw and be certified by the Minnesota Crop Improvement Association (MCIA) to be free of noxious weed seeds, seed bearing stalks, and/ or other reproductive propagules as defined by rules and regulations of the Minnesota 1 , 1 '( f . Department of Agriculture. Documentation verifying that the mulch has passed MCIA field inspection shall accompany the material upon delivery to the job site. At the time of delivery, the mulch shall be in an air dried condition. Fertilizer - It is always recommended to take soil tests to determine the existing soil fertility in order to chose an appropriate fertilizer based on the soil deficiencies. It is also recommended to chose a slow release fertilizer with 80% Water Insoluble Nitrogen (WIN) and 0% chlorides. If you are going to use a generic fertilizer it is recommended to use a 10-10-20 NPK analysis fertilizer (see below for specification.

The Signs will be placed on alternate lot lines at the wetland or mitigation area edge facing the homeowner's property. Appendix C Restoration Plan Seed Mix I 1 I l SEEDING AND PLANTING PLAN Albert Villas Development Albertville, Minnesota The Local Governmental Unit (LGU) for the project is the City of Albertville. Edina Development is proposing construction of a three replacement mitigation basins as replacement for the unsuccessful mitigation areas and additional wetland impacts. The goal of the mitigation is to provide a high quality Type 2, 3 wetlands. The current vegetation of the existing wetlands mainly consists of invasive, exotic reed canary grass (Phalaris arundinacea) . The replacement will be accomplished through the creation of 1.07 acres of new wetland credit (NWC) and 0.57 acres of associated public value credit (PVC) comprised of upland buffers. Creation of the mitigated wetlands will involve excavation using backhoes and other small and heavy equipment. Best management practices, such as silt fence, hay bales, and mulch will be in place until native ground cover establishes itself. Site Preparation The newly constructed wetlands will be constructed by excavating three irregular shaped basins to four feet below the existing ground level. The excavation will gradually slope up with the side slope ratio of, at maximum, a 10:1 to meet the existing elevations. The excavated area will be backfilled with approximately 1 foot of organic topsoil and compacted, leaving a gently undulating bottom. The replacement mitigation wetland and replacement wetland will then be seeded with an appropriate wet meadow seed mix (BWSR seed mix W2 or similar) and will be scheduled to follow the MNDOT recommended seeding maintenance procedures (MNDOT 2571). Hydrology to the replacement mitigation wetland areas A and B will be supplied by the outlet of Swamp Lake. The proposed route will direct water to replacement mitigation area A, then to a stormwater pond, which will out let into replacement area B and then to County Ditch No.9. Replacement Area C will receive hydrology from overland flow from the surrounding watershed and outlet to County Ditch No.9. If any vegetation is noticed within the mitigation areas, it should receive backpack-sprayed herbicide treatment with an aquatically labeled glyphosate (Rodeo™ or equivalent) in order to control the invasive species. t Seeding Plan Appropriate seed mixtures for the proposed Type 2 wetlands are listed in the Guidelines For Restoring & Managing Native Wetland Vegetation by MNDOT and BWSR (Guidelines). The applicant, by using the seeding and planting methods as recommended in the Guidelines and maintenance methods described below, is committed to assuring the success of a high quality Type 2 - PEMB, wet meadow. Below are excerpts from the Guidelines pertaining to the seeding of a type 2 4 wetland and the associated upland buffer. Wetland T e Shallow marshes (Type 3), deep marshes (Type 4), open water wetlands (Type 5) Mixture(s W1, W2 or W3, appropriate upland mix (U1-U7).

Notes On Where & How To Use Seed Mixes: Wi - Contains all OBL species, which grow in the emergent aquatic (shallow marsh) zone. It can be used state-wide. This zone can also be planted with live plants and/or pre-vegetated mats (PVM). The WI mix was developed for use on projects that are too large for planting of live plants to be economically feasible. W2 - Contains sedge meadow & wet meadow species which grow in the saturated & moist soil (sedgelwet meadow) zone. It can be used state-wide. W3 - Contains wet prairie species which grow in the saturated & moist soil (sedgeJwet meadow) zone of prairie pot-holes. It is for use in the prairie grassland area of the state. W4 - Is for swales and wet ditches. W5 - For same areas as W2. Mix was developed for BWSR cost share projects. It contains fewer species and is cheaper. W6 - For same areas as W3. Mix was developed for BWSR cost share projects. It contains fewer species and is cheaper. Ri - For streambank and floodplain restorations. See notes in mix tabulations. Ui-U6 - Prairie mixes. See notes in seed mix tabulations for where to use them. U7 - Contains woodland edge/savanna species. For use in forested regions of the state. US - Contains mesic prairie species. Mix was developed for BWSR cost share projects. It contains fewer species and is cheaper. U9 - Contains dry prairie species. Mix was developed for BWSR cost share projects. It contains fewer species and is cheaper. Ui0 - BWSR cost share mix. For use on berms. Uii - BWSR cost share mix. For use in grassed swales. I l Construction of the mitigation basins at elevations of the existing wetlands and the surficial runoff from the storm water treatment systems should adequately hydrate the soils. The area may need to be dewatered while construction activities are being conducted. The area will then be seeded with a W2 seed mixture, as suggested in the Guidelines. The seed mixture will be broadcast spread or have pre-vegetated mats placed in wet areas, the combination covering the entire area. The area will then be mulched using the type and method for mulching as recommended in the MnjDOT Seeding Manual 2000.

This is critical in the first three to five years and should be recognized as integral to the wetland mitigation success. Management will include both eliminating non-native and invasive vegetation along with creating ideal conditions for native plants to flourish. Some invasive plants are strong competitors and without management, could hamper establishment of the native planting. Invasive wetland species such as purple loosestrife, reed canary grass, and cattail exist in many urban wetlands, and may contribute seed to the restored area. Invasive species such as common buckthorn, yellow and white sweet clover, spotted knap-weed, and Canada thistle are of concern in upland areas. Non-native plant removal/ management and careful monitoring is vital during the early stages of the restoration. As native plants slowly grow and spread over the years, and as thatch builds, the site will become less vulnerable to non-native and invasive species. Without non-native and invasive plant removal/management it is highly unlikely that a diverse native plant community will become established. Methods for InvasivefNon-native Species Control 1) Mowing During the first two years of plant establishment mowing at a height of 6 to 10 inches where feasible, during the growing season, will reduce competition from annual weeds. Mowing allows light to reach the small native seedlings and reduces competition from weeds for water and soil nutrients. 2) Spot application of herbicide Individual invasive plants (including cattail) can be eradicated through wick application or spraying of herbicide. Rodeo or other Minnesota Department of Natural Resources herbicides approved for use near / in water bodies should be applied by a licensed applicator at the appropriate times to control individual plants. 3) Eradicate large infestations with herbicide The most effective method of eradicating large colonies of plants is to wick-apply or spray them with herbicide. Use Rodeo when spray may come in contact with water and Roundup in upland situations. Repeated application will probably be necessary. Apply to green, actively growing foliage. Herbicides can effectively control herbaceous non-native vegetation when applied in spring or fall. Take great care not to apply herbicide to surrounding native plants. A very small amount of herbicide can kill a plant. i j . , 1 4 , I f i l i 4) Cut woody stems and apply herbicide to wound All undesirable woody plants, greater than 1/4-inch in diameter, which cannot be hand-pulled should be cut down to expose the vascular tissue, or cambium. Herbicide painted on the cambium will be transported within the plant, eventually killing it. Cut the woody plant at a height that ensures the native herbaceous plants will not have contact with the stump and herbicide. This procedure should not be conducted while woody plants are dormant. Vegetation Maintenance Schedule 1) Year 1 After planting, annual weeds should be mowed (before seed set) to a height of six to ten inches or removed as needed. The site will likely require one to two mowings. Spot herbicide application, or hand removal, of aggressive weeds such as reed canary grass and thistle should also occur when the management crew is at the site to mow. Also, at the beginning of the maintenance period any undesirable shrubs in the mitigation areas should be sprayed with an appropriate herbicide. July (middle) - Mow wetland (where feasible) at a height of six to ten inches. Spot spray aggressive invasive and non-native species. September (early)- Mow wetland at a height of six to ten inches, spot spray invasive species. Buckthorn is best treated with herbicide in the fall when the plants are storing energy. Buckthorns lose their leaves later in the season than native woody plants, which allows for easier buckthorn identification and herbicide treatment in late September through early November. 2) Year 2 Conduct an initial site visit in May to evaluate status of restoration and determine management tasks for the year. These will likely include: Spring - Conduct burn approximately every third year starting the second or third year. May - Spot spray invasive species. Mow wetland at a height of six to ten inches (mowing may not be needed or may not be possible depending on wetness and condition). Re-seed areas that do not meet the performance standards. July - Mow prairie at a height of six to ten inches, spot spray invasive species. September - Spot spray invasive species. 3) Year 3 Conduct an initial site visit in May with to evaluate status of restoration and determine management tasks for the year. These will likely include: May - Spot spray invasive species. Re-seed areas that do not meet the performance standards stated below. JuneIJuly - Spot spray invasive species. September - Spot spray invasive species. 4) Year 4 and beyond Inspect wetland annually to assess its condition. Conduct spring or fall burn in year 5 and then approximately every third year thereafter (fall burns tend to increase forb diversity while spring burns tend to increase grass density). May-September - Apply herbicide to invasive species that are not controlled by burning. This should be required only once per year. Performance Standards of Wetland (NWC) and Upland (PVC) Establishment 1) Year 1 This paragraph applies to the first full growing season after wetland and upland buffer establishment. Seedlings of at least 4 native species shall be widely dispersed through the wetland and upland buffer areas. No areas of bare soil larger than 9 square feet shall exist. There shall be no more than 20% total coverage of exotic, non-native, or invasive vegetation (such as cattail) within the wetland area. The upland buffer area shall have greater than 50% total areal coverage dominated by the cover crop and native vegetation. 2) Year 2 This refers to the second full growing season after wetland and upland establishment. The wetland and upland buffer shall have at least 30% of all species contained in the specified seed mixes present within each area. No areas of bare soil larger than 4 square feet shall exist. There shall be no more than 20% total areal coverage of exotic, non-native or invasive vegetation within the wetlanmd area. The upland buffer area shall have greater than 70% total areal coverage by the cover crop and/or native vegetation. 3) Years 3-5 This section refers to years 3 through 5 after wetland and upland establishment and should be applied as long-term standards. The wetland and upland buffer areas shall have a minimum of 80% total areal coverage of native vegetation. The wetland and upland buffer areas shall contain 50% of all species contained in the specified seed mixes. The wetland and upland buffer areas shall have no bare patches of soil. There shall be no more than 20% total areal coverage of exotic, non-native, or invasive vegetation within the wetland and upland buffer areas. i 1 1 i l l Excerpt from the Mn/DOT Seeding Manual 2000, Cover/nurse Crops - Cover crops provide a quick short-term vegetative cover while the permanent native species are establishing. A cover crop reduces the soils erosion potential and moderates the native seedlings microclimate during establishment. Typical cover crops in Mn/DOT's native mixes include oats/winter wheat, annual rye grass and slender wheatgrass. Winter wheat is substituted for oats during fall plantings. The annual rye grass provides good cover in early spring but does not do well in late spring and summer. It also does well dormant seeded. ReGreen (a hybrid cross between slender wheat grass and winter wheat) listed in the 2000 Specification B-series mixtures is used instead of oats/winter wheat for temporary cover (ReGreen will persist for up to three years). Native species seeded in the fall perform very well, but it is critical that winter wheat (or ReGreen) and annual rye grass be used as specified in the mixes to ensure adequate vegetation establishment on erodible sites. One drawback Mn/DOT has observed to ReGreen that is that it does not perform very well in saturated soils, shaded areas, or when it is interseeded into dead sod. NOTE: The new native seed mixtures (310 - 350) have a much higher cover crop rate as compared to the 2000 B- series mixtures. When comparing seeding rates, note that 85% of the new mixture rates as compared to approximately 50% of the 2000 B-series mixtures are comprised of cover crop species. Cover crop species are inexpensive. Temporary Erosion Control- It is recommended to protect a new seeding by covering it with mulch or an erosion control blanket. In general, slopes that are 1:3 (vertical : horizontal) and flatter should be mulched with a clean grain straw or native grass mulch and disc anchored following seeding. Mulching should attempt to achieve 90% coverage of the exposed soil surface. This generally requires about 2 tons per acre of straw mulch. It is also recommended to use a high quality weed free mulch such as MCIA Certified Weed Free mulch (see below for specification) or a native grass (prairie) mulch. On slopes that are steeper than 1:3 it is recommended that the seeding be covered with an erosion control blanket. Generally, straw blankets containing double netting (Straw 25) perform best with native plantings. If seeding is being done in a ditch or swale that will receive moderate water flows for periods of time, it is recommended that a straw / coconut blanket be used to cover it. Other more severe situations such as very steep slopes and/ or channels exposed to high water velocities will require more specialized treatments that are not covered in this manual. NOTE: Mulches derived from pasture hay containing reed canary grass, smooth brome and other introduced forage species may contain enough seed of those species to ruin your native grass and forb planting. They are not recommended for use with native plantings. Generic Specification Example: MnfDOT Type 3 (MCIA Certified Weed Free Mulch) - This mulch shall consist of clean grain straw and be certified by the Minnesota Crop Improvement Association (MCIA) to be free of noxious weed seeds, seed bearing stalks, and/ or other reproductive propagules as defined by rules and regulations of the Minnesota , ' l [ t Department of Agriculture. Documentation verifying that the mulch has passed MCIA field inspection shall accompany the material upon delivery to the job site. At the time of delivery, the mulch shall be in an air dried condition. Fertilizer - It is always recommended to take soil tests to determine the existing soil fertility in order to chose an appropriate fertilizer based on the soil deficiencies. It is also recommended to chose a slow release fertilizer with 80% Water Insoluble Nitrogen (WIN) and 0% chlorides. If you are going to use a generic fertilizer it is recommended to use a 10-10-20 NPK analysis fertilizer (see below for specification. A general rule of thumb is that native grasses and forbs require about 50% less Nitrogen and 25% more Potassium than turf and forage species. Generic Specification Example: Fertilizer (Type Slow Release) - The fertilizer used for this project shall be a commercial grade of slow release complete fertilizer applied at a rate of 400 lbs/ acre at the time of preparing the seed bed for seeding. The fertilizer shall contain a 10-10-20 (NPK) analysis, consisting of 80% Water Insoluble Nitrogen, 0% Chlorides, and should include sulfur and iron as well (not less than 1 % and not more than 8% added sulfur and iron).
