A number of activities as follows are needed in order to proceed with a wetland <br /> improvement approach: <br /> - Additional soils exploration and wetland delineation. <br /> - A possible MnRAM or equivalent wetland classification. <br /> - A determination if the wetland falls under Wetland Conservation Act (WCA) <br /> regulation as well as RCWD. <br /> - Determination of the best location of the constructed wetland relative to the <br /> delineated wetland edge. <br /> - Determination that the existing wetland will sustain no net loss in function and value. <br /> - Balance of cut/fill activities for the purposes of floodplain regulation. <br /> D. Other BMPs <br /> Other storm sewer improvements such as sump manholes or proprietary grit chambers to <br /> collect sediments will be considered as part of the project. The design will provide for <br /> erosion control and energy dissipation at storm water outfall points, and pre-treatment <br /> prior to discharge into basins or rain gardens. <br /> Erosion Control <br /> As part of the project plans and specifications, staff is required to prepare a storm water pollution <br /> prevention plan (SWPPP) for the purposes of enforcing erosion and sediment control rules. The <br /> SWPPP will include erosion and sediment control methods that will be implemented throughout <br /> the project. Silt fence, bio-rolls, erosion control blanket, and other best management practices <br /> will be utilized where direct runoff might occur. Inlet protection will be used to protect both the <br /> existing and new catch basins during construction. Street sweeping will occur, as needed, on all <br /> paved street surfaces throughout the project, including intersecting streets. Watering of exposed <br /> soils and aggregate material would be done as a dust-control measure. An erosion and sediment <br /> control plan sheet and storm water pollution prevention plan will be created during the design <br /> phase of this project. Immediate turf establishment in areas of soil disturbance will be required <br /> such as placing seed and erosion control blanket. After street and utility work is completed, sod <br /> will be placed as the permanent turf establishment in all disturbed areas. The City in <br /> coordination with the watershed district will closely monitor all erosion and sediment control <br /> measures throughout the construction process. The selected contractor will be required to install <br /> all preventative measures and maintain them as required by the City, RCWD, MPCA, and other <br /> regulatory agencies. <br /> 10 <br />
