AFTER SOIL IS STABILIZED, REMOVE TEMPORARY SEDIMENTATION AND EROSION CONTROL MEASURES. 0 a s ur e rea I sq. . . acres EROSION AND SEDIMENT CONTROL PLAN NOTES PROJECT NARRATIVE: The project is the construction of a residential development containing single family housing Public water is being installed in sections as the real estate is developed and the roads are constructed. Soils in this area have been moped by N.R.C.S. as Conetoe Loamy Sand, Portsmouth Loam, and Tomotley Fine Sandy Loam. SOIL STABILIZATION: All disturbed soils shall be stabilized by seeding and/or sodding within 15 working days or 30 colender days (whichever is shorter) of construction completion or the completion of the land disturbing activity. It is the contractors responsibility to establish a dense ground cover capable of stopping erosion. The Erosion and Sediment Control measures that follow are intended to be minimum standards. When erosion persists other more stringent measures may be necessary to control erosion. Apply fertilizer, and agricultural lime as required by soil test or as a minimum follow this schedule: Apply fertilizer in the amount of 500 pounds per acre of 10-10-10 fertilizer. Apply 2,500 pounds/acre of agricultural limestone. Where possible scarify soil to work the fertilizer and soil into the soil. Mulch the area to be stabilized with wheat straw at the rate of 2 tons/acre. Anchor straw when necessary with netting or asphalt. In some instances it may be necessary to use pre -manufactured erosion control mats like the excelsior mat. Seeding: 1) If Temporary Vegetation is to be established in winter/spring/fall apply 125 pounds/acre of annual rye grain. If Temporary Vegetation is to be established in the summer months apply 25 pounds per acre of Bermuda Grass and 25 pounds per acre of German Millet. 2) Permanent Vegetation shall be established with a mixture of 40 pounds/acre of Bahiagrass, 10 pounds/acre of Bermuda, and 10 pounds/ acre of German Millet. When top seeding over Temporary Vegetation containing a good stand of Bermuda and Millet, only Bahiagrass will be required. 3) Sodding may be required when slope stabilization is difficult to establish. Select a sod species compatible with the application and apply sod strips down the length of the slope. Fasten sod as necessary to prevent slippage. 4) Final slopes in all graded areas shall not exceed a slope of 3:1. 5 Geotextil f should be r e fabrics or special mulch protection ' n such as fiberglass roving or straw and netting sh d provided until vegetation is full P P e tlo 9 9 9 P 9 Y established; this must be used whenever the design velocities exceed 2.0 ft/sec for bare soil conditions. MAINTENANCE: Erosion control devices are to be checked after significant rainfall events but not less than twice monthly. Remove sediment and repair erosion control devices as necessary. Check slopes being stabilized for signs of erosion after all significant rainfall events and repair as necessary. Reseeding and mulching of erosion damaged areas is required. Perform routine maintenance and mowing of stabilized areas, including ditches and swales. Temporary or permanent groundcover shall be provided on all exposed slopes witnin 21 calendar days following completion of any phase of grading; and a permanent groundcover for all disturbed areas within 15 working days or 90 calendar days (whichever is shorter) following completion of construction or development. INTENTION OF THIS EROSION AND SEDIMENT CONTROL PLAN Protect disturbed areas from erosion. Stabilize disturbed areas as soon as possible. Minimize the length of time disturbed soil is exposed. Minimize the velocity of stormwater runoff. Retain sediment on site with silt check dams and silt fencing. SOURCE: VA.
