Site Grading: <br />The site grading is planned to begin in the Spring of 2013. The entire project is proposed <br />to be graded in one phase; the graded area is +/- 2.5 acres. It is our design objective to <br />balance the site with on-site material, some import of suitable structural fill material may <br />be necessary for building pad, street, and retaining wall construction. As the final design <br />analysis is completed we will provide detailed construction plans for the entire project to <br />the City of Roseville. <br />Stormwater: <br />The stormwater facilities proposed in "Josephine Heights" are illustrated on the enclosed <br />preliminary plans. Runoff from the site will be directed through rear yard swales and <br />concrete curb and gutter to the proposed infiltration basins. These infiltration basins will <br />provide infiltration, storage and rate control for stormwater runoff, and treatment for <br />particle and sediment removal. The proposed infiltration basins will consist of a layer of <br />buckshot rock to provide underground water storage, and a layer of bioretention soil to <br />provide treatment and retention for plat absorption. Plantings and mulch will be utilized <br />as ground cover above the infiltration basins to provide a clean looking landscaped yard. <br />These infiltration areas will outlet stormwater that does not infiltrate through the outlet <br />culvert and into the city storm sewer system. The stormwater plan will provide adequate <br />treatment and storage to meet the City of Roseville and Rice Creek Watershed District <br />requirements. <br />Wetlands: <br />There are no existing jurisdictional wetlands on the site, please see the report prepared by <br />Arrowhead Environmental Consulting. <br />Traffic: <br />"Josephine Heights" proposes one entrance to the site with access from Millwood <br />Avenue. The proposed public street will be a cul-de-sac that is about 200 feet to the <br />center of the bubble. It is anticipated that the 6 home sites will generate 10 trips per day <br />per home site for a total of 60 trips per day. The additional traffic generated from this <br />site is not anticipated to have a noticeable impact on the existing traffic in the area. <br />Homeowner's Association and Restrictive Covenants: <br />The developer will prepare restrictive covenants and standards that will apply to the <br />entire neighborhood during both the initial development and the overall operation of the <br />subdivision. <br />-3— <br />
