• 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 C 103: High Visibility Fence 2-ESTABLISH CONSTRUCTION ACCESS The existing paved area will serve as the construction entrance. 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, then the contractor shall place silt fencing down slope from the disturbed areas as shown on the SWPPP. Best Management Practices (BMPs)to be used: • • BMP C 103: High Visibility Fence S-STABILIZED SOILS We do not expect any stockpiles on this project. All new exposed areas are expected to be covered with sand 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. Any land disturbed areas outside of the proposed horse arena will be permanently seeded.
