MINIMUM REQUIREMENT #2 — SWPPP SWPPP Element 1: Preserve Vegetation and Marking Clearing Limits Site disturbance limits will be shown on the SWPPP as part of the construction plans, and will ultimately create a disturbance area of approximately 65,000 square feet. This disturbance area is currently mostly grass area, with some existing paving. SWPPP Element 2: Establish Construction Access Construction access will come from the alley south of the site. A temporary gravel construction access BMP shall be utilized at this access point. It is likely that occasional alley cleaning will be necessary, and notes in the TESC plan call for this if needed. SWPPP Element 3: Control Flow Rates Due to the relatively small size of the two on-site basins and sandy subsurface soils, the runoff increase during construction is expected to be small. Therefore this Element is not applicable. SWPPP Element 4: Install Sediment Controls Silt fence shall be installed across the downslope side of the disturbance area prior to construction activities, as well as straw wattles in the more defined draws, as shown on the TESC plan. An interceptor swale around the infiltration facility can be used to divert sediment-laden water around the facility. Maintenance and function requirements are included in the construction notes. These BMPs should be adequate for a project of this size. The plans also contain cover measures for exposed soils to prevent sediment from being generated. SWPPP Element 5: Stabilize Soils The plans depict cover and stabilization measures for excavated soils and exposed ground. Notes limiting duration of exposure are also included on the plan. Permanent soil stabilization will be achieved with paving, or with landscaping and/or lawn, including BMP T5.13 — Post construction soil quality for disturbed areas, which is included in the plan notes. The flat slopes in the development area should make stabilization feasible with these measures. SWPPP Element 6: Protect Slopes There are no significant slopes within or immediately adjacent to the development area. Therefore, this Element is not applicable. SWPPP Element 7: Protect Permanent Drain Inlets Inlet protection and maintenance of such shall be provided as shown on the TESC plan. SWPPP Element 8: Stabilize Channels and Outlets There are no existing channels in the vicinity of the development area, and all areas outside the development area are currently well-vegetated and stable. Therefore, this q
