(3) The Board recognizes the importance of strict erosion and sediment control during construction and urged Roseville to carefully control construction to minimize erosion. The Board suggested that this development be reviewed with the Ramsey Soil and Water Conservation District to utilize their expertise in this area. The City of Roseville will not issue any. construction permits until the school district plans have been reviewed and approved by the Ramsey Soil and Water Conservation District. (4) The Board emphasized the need to design the site drainage to protect the existing wetlands. Protection of existing wetlands was considered a must. A great deal of analysis and design work has been done to ensure that the stormwater bounce in the existing wetlands is minimized. Recent criteria developed by the PCA in cooperation with other environmental and governmental agencies sets standards for new wetland bounce that are based on the type of wetland. These standards are published in a draft report titled "Guidance for Evaluating Urban Stormwater and Snow-melt Run-offImpacts to Wetlands." These criteria have been met in all cases. (5) The Board recognized that many details of the stormwater plan have yet to be finalized. The Board emphasized the need to resolve all the stormwater details prior to construction. All of the stormwater details, with the exception of detailed plans for the outlet to Lady Slipper Park, have been completed. No permits will be issued until a plan for the Lady Slipper Park outlet has been finalized. The Metropolitan Council recently solicited projects for the "Twin. Cities Water Quality Initiative Educational Grant-1995." The City of Roseville, with help from BWSR, has submitted an application to install silt sacks in the catch basins to be constructed as part of the storm sewer system on the school district property. This new technology is meant to collect heavier sediment before it enters the stormwater system. It is especially useful in areas, such as the school district site, where construction will occur over a number of years.. The school district plans to construct all the public improvements in 1995. Home construction will, however, occur over a two to three year period. If a grant is awarded, the school district has agreed to install the silt sack devices, and the City will monitor, report, and maintain them. We are optimistic that the $7,300 grant will be awarded.. A copy of the grant application is included with the "Letters Sent" item of this agenda. The school district has received approvals from the City Council and is currently finalizing construction plans. They expect to begin grading the site in May and begin street and utility construction in early July. It is their goal to have model homes completed for the fall of 1995 preview.
