To meet these requirements, a Construction Stornwater Pollution Prevention Plan (S WPPP) has <br />been provided. The following addresses Minimum Requirements 1 to 5: <br />Minimum Requirement#l: Preparation ofstormwater site plan <br />A Stormwater Site Plan/Building Site Plan has been prepared. <br />Minimum Requirement #2: Stormwater Pollution Prevention Plans (SWPPP) <br />SWPPP drawings and the required elements have been prepared and are a stand-alone <br />document from this report. The BMPs indicated on the plans will be implemented during <br />construction. Additional BMPs may be used on the site depending upon weather <br />conditions. <br />Minimum Requirement #3: Source Control of Pollution <br />During construction S WPPP BMPs will be implemented, based on SMMW W Volume IV, <br />Chapter 5, as shown on the SWPP plans. This project is not required to have source control <br />BMPs after construction is completed. <br />Minimum Reguirement#4: Preservation of natural drainage and outfalls <br />The proposed site development is not expected to have off -site drainage impacts. This <br />project will disperse stormwater runoff from the natural drainage location. On -site BMPs <br />will he used to mitigate potential erosion issues and control runoff. For more information <br />about BMP details and placement please refer to Section I of this report and Site Plans <br />associated with this project. <br />Minimum Requirement #5: On -site Stormwater Management <br />The proposed project triggers Minimum Requirements l through 5; therefore, the proposed <br />project will use BMPs from List #1 of SMMWW Volume I, Table 1-3.2 to mitigate <br />storrowater runoff. <br />BMPs for Lawn and Landscaped Areas: <br />• BMP T5.13: Post -Construction Soil Quality and Depth is feasible. Existing topsoil <br />will be stockpiled and used for final stabilization. <br />BMPs for Roofs: <br />• BMP T5.30: Full Dispersion is not feasible due the lack of 100 ft minimum flow <br />path. <br />• BMP T5.10A: Downspout Full Infiltration System isnotfeasibleduetothe shallow <br />depth to water table. <br />• BMP T730: Bioretention is not feasible due to the shallow depth to water table. <br />
