STORMWATER MANAGEMENT PLAN (SWMP) <br />AND EROSION AND SEDIMENT CONTROL REPORT <br />FOR <br />ST. VRAIN LAKE GRADING IMPROVEMENT PLANS <br />Page 4 <br />f. Install specific BMPs as shown on the Stormwater Management <br />Plan (SWMP) sheets, included in the construction plan set, to <br />provide erosion protection prior to landscaping and re-vegetation. <br />Detailed descriptions and exact locations of BMPs are provided in <br />the Lake Grading Construction Plan set. <br />g. Complete final site grading including replacing stockpiled topsoil. <br />In addition, clean out and re-grade (as necessary) detention and <br />sedimentation ponds used for water quality capture purposes <br />during construction to conform to the design of the permanent site <br />drainage system. <br />h. Final (permanent) seeding, sodding, planting and landscaping will <br />be the responsibility of the owner. <br />i. Remove temporary control measures. <br />Sequencing of construction activities will progress as rapidly as <br />practical to minimi2e the amount of time that portions of the site are <br />disturbed. Areas that will be inactive for more than 30 days will be <br />surtace roughened to reduce erosion, slow runoff velocity and promote <br />infiltration. Additionally, permanent slopes steeper than 3:1 may need <br />blankets, matting or netting for long-term exposure (greater than 2 <br />weeks). Inactive areas will be seeded with an approved temporary <br />native seed mix when the weather conditions are such that growth of <br />native grasses from seed is possible. <br />2. Post-Construction Site Inspection <br />Following the completion of the project, including final re-vegetation and <br />landscaping, the SWMP Administrator will inspect areas that have been <br />seeded and landscaped to assure that the re-vegetation and <br />landscaping have been successful in establishing uniform ground cover <br />_-__-_-- (7.0_°!o-of_pre=disturbance-cover-criteria-for-re-vegetation). - -I~-re------- <br />vegetation has not been successful, spot re-vegetation or other <br />remedial actions should be implemented to assure compliance with the <br />i <br />., <br />
