• <br /> Other Hard Surfaces: <br /> 1. Full Dispersion: Not feasible (see above). <br /> 2. Rain Gardens: Not feasible (see above). <br /> 3. Permeable Pavement:Not feasible due to existing site soils (silt and clay found in <br /> test pits 2 and 5). <br /> 4. Sheet flow dispersion: Selected, the runoff generated by the concrete driveway <br /> surfaces will be dispersed on-site. Runoff will sheet flow into 2-foot wide transition <br /> zones before being dispersed over amended or existing soils with 10-foot minimum <br /> required flow paths for sheet flow dispersion. <br /> 5. Concentrated Flow Dispersion: Higher priority option selected. <br /> 8. SUMMARY <br /> This project proposes to construct less than 5,000 sf of new hard surfaces. As a result, the <br /> use and land cover for less than 5,000 sf of the site will be converted pervious to impervious <br /> surfaces. Stormwater management techniques have been incorporated into the design. <br /> Therefore, the.stormwater design for-this-project has met or exceeded all of the applicable <br /> Minimum Requirements 1-5. <br /> Lucas MFH 2O-0715 <br /> March'2021 Page 10 <br />
