I SWPPP ELEMENTS 1 —PRESERVE VEGETATION/MARK CLEARING LIMITS The land disturbance activities for development requires the consideration to be given to minimize the removal of existing trees, disturbance and compaction of native soils, except as needed for building purposes. The duff layer, native soil and vegetation shall be retained in an undisturbed state to the minimum degree practicable. Best Management Practices (BMPs)to be used: • BMP C101: Preserving Natural Vegetation • BMP C103: High Visibility Plastic or Metal Fence 2-ESTABLISH CONSTRUCTION ACCESS A temporary construction entrance is not required. Best Management Practices (BMPs)to be used: • None Required 3-CONTROL FLOW RATES Flow rates will be controlled by using SWPPP Element#4, sediment controls. 4-INSTALL SEDIMENT CONTROLS Due to the permeability of the site soils, surface flows from the site are expected to be negligible and therefore no sediment controls are needed. If the contractor notices that dirty storm water is leaving the site, than the contractor shall place silt fencing down slope from the disturbed areas as shown on the SWPPP. Best Management Practices (BMPs)to be used: • None Required 5-STABILZED SOILS We do not expect any stockpiles on this project. All new exposed areas are expected to be covered with gravel or building within 48 hours of exposure. If required, all exposed soil and any soil stockpile will be stabilized. The soil stockpile will be located within the disturbed area shown on the SWPPP plan. Any stockpiles will be covered in plastic if left un-worked. No soils shall remain exposed and unworked for more than 2 days between October 1 and April 30. The land disturbed areas will be permanently seeded. The only disturbed areas on this site will be the around the house for footings. These are made with minimum disturbance to the existing area.
