    1. Design the garden A rain garden is an area in your yard planted with native plants that collects water run-off from your roof, driveway or other hard surfaces. I t acts as an infiltration system that keeps our water out of the storm water system, re-charging the ground water. Rain gardens reduce the amount of storm water that ends up in our streams and lakes, and helps to improve water quality by filtering through plants and the soil.

    9. Soil’s data From the Michigan Center for GIS http://www.dnr.state.mi.us/spatialdatalibrary/metadata/SSURGO_metadata.htm http://datagateway.nrcs.usda.gov/NextPage.aspx MUKEY Map Unit Key for linking information in the National Soil Information System Design Area is mostly code 19B - Perrinton loam, 2 to 6 percent slopes The Perrinton soil is well drained to moderately well drained soils formed in glacial till on ground and end moraines. These soils have slow permeability.

    10. Soil’s map

    11. Design the garden What should be the size? Minimized earthwork and excavation Study profiles and sections along the proposed location Examine slope map Draw your proposal Estimate the elevations along the points of the proposed garden,. Estimate cut and fill

    12. Size requirements Estimate the area from which your garden will get rain. Rooftops, paved areas, parking lots, roads that will drain to the garden. For sandy soil, your rain garden should be 20-30% of the drain area. For example, if your roof and driveway measures 1200 square feet your rain garden should be 20- 30% of that, or 240-360 square feet. For clay soil, your rain garden should be about 60% of the drain area (Clay absorbs water very poorly; the varieties of rain garden plants that do well in clay take at least three years to get established. Soil replacement may be the best choice in clay soils). If soil is replace with rain garden mix (50-60% sand, 20-30% topsoil, 20-30% compost), then area should be 20-30% of the drain area. Rain gardens for single-family homes will typically range from 150 to 400 square feet. But remember; any size rain garden, even a small one, will contribute to solving local water pollution problems.

    13. Area calculation Parking area that should be drained is Birkham Parking:7865 sq. ft Rec center parking: 24294 sq. ft Building area Birkham : 11192 sq. ft Total: 43351 sq. ft The designed rain garden is 6160 sq. ft which is 14% - not enough but better than nothing

    14. Proposed Design Will require excavation and uprooting of the trees? Minimize the amount of earth work (project budget) Follow the contour line
