site. Show ordinary high water marks of all navigable waters, 100- <br />year flood elevations and delineated wetland boundaries, if any. If <br />not available, appropriate flood zone determination or wetland <br />delineation, or both, may be required at the applicant's expense. <br />c. Map of watershed drainage areas showing direction of flow for pre <br />and post construction drainage and soil types. <br />d. If the site has proposed infiltration basins or when deemed <br />necessary by the Engineer, then the following information shall <br />also be included; infiltration rates, depth to bedrock, and depth to <br />seasonal high water table. <br />e. Existing and proposed grades showing drainage on and adjacent to <br />the site. <br />f Existing and proposed impervious surfaces. <br />g. Steep slopes of 12% more. <br />h. Location of all areas not to be disturbed during construction <br />including trees, vegetation, and appropriated areas for infiltration. <br />Proposed grading or otherland-disturbing activity including areas <br />of grubbing, clearing, tree removal, grading, excavation, fill and <br />other disturbance; areas of soil or earth material storage <br />When deemed necessary by the Engineer, the following <br />information shall be included; quantities of soil or earth material to <br />be removed, placed, stored or otherwise moved on site, and <br />delineated limits of disturbance. <br />k. Locations of proposed runoff control, erosion prevention, sediment <br />control, and temporary and permanent soil stabilization measures. <br />If more than 10 acres are disturbed and drained to a single point of <br />discharge, temporary sediment basins must be installed, however, <br />if the site has special waters as determined by the City or defined <br />by the NPDES Consriuction Permit requirements, then temporary <br />sediment basins must be installed where 5 or more acres are <br />disturbed. When site restrictions do not allow for a temporary <br />sediment basin, equivalent measures such as smaller basins, check <br />dams, and vegetated buffer strips can be included. <br />2. SWPPP Specifications. The Stormwater Pollution Prevention Plan <br />(SWPPP) shall include a specifications section that addresses and includes <br />the following requirements: <br />Erosion Control Ordinance 927- 3 <br />
