The stabilized construction entrance and filter inlet protection for existing storm inlets and pipes shall be installed prior to beginning other earth disturbing activities. 9. Perimeter protection, silt fences, diversion berms /swales, rock filters, also shall be installed prior to starting other earth disturbing activities. 10. Provide rock filter outlets along silt fence in locations where the fabric fence is overtopped or undermined during the Work, as required. See Detail 8, this sheet. Whenever possible, erosion and sediment control measures shall be constructed and installed prior to performing other earth disturbing activities. 12. Minimize erosion from exposed areas by providing and maintaining temporary or permanent stabilization measures. Erosion control measures to protect exposed areas shall be installed at the end of the day's work or within 24 hours of the completion of the earth disturbing activity, as applicable for the type of measure. 11. 13. All disturbed areas shall be seeded and /or stabilized upon completion of the earth disturbing activity. 14. All seeded areas shall be stabilized per the Specifications. Seeded and planted areas shall be stabilized with an anchored, crimped or tackified mulch and seed mixture. 15. All graded areas, (lawns, basins, swales, etc.) with slopes equal to or steeper than 6H:1V shall be stabilized with an erosion control blanket per the Project Specifications. Constructed landscaping mounds shall be stabilized with an erosion control blanket. Soil stockpiles shall be seeded and mulched to minimize erosion. 16. Areas to be paved shall be stabilized with a temporary stone cover. The temporary stone stabilization shall be equivalent to the proposed stone sub -base material. Adequate sub -base depths shall be maintained during construction and provided prior to final paving. Stone stabilization shall be installed per the paving specifications and details (See CL500 series drawings). 17. Install pipe and grate inlet protection measures and pipe outlet protection as new pipes or pipe extensions are installed. Limit excavation to the work that can be performed that day. Trenches shall be seeded and mulched as part of the backfili operation. 18. Wrap all grates with filter fabric to prevent debris and sediment from entering storm system. Check weekly and after each storm event for debris and sediment. Clear blockages as identified. Torn or damaged fabric shall be replaced. 19. Temporarily seed and stabilize all disturbed areas where work will cease for 5 days or longer. 20. Erosion and sediment control measures shall be maintained until the area of the Work is 95% stabilized.

Blanket shall be biodegradeable wood, straw or coconut -fiber mat enclosed in a photodegradable mesh. 2. Install per manufacturer's recommendations. 3. Use 6 inch, 11 ga. wire "U" staples. Longer or heavier gauge staples may be necessary for some soils. 4. Use Staple pattern shown, or per manufacturer's recommendation, whichever requires greater staple frequency. Maintenance: 1. Inspect weekly, and after storm events. Especially at edges of blankets were erosion may undercut the material. 2. Repair and replace damaged material and eroded base areas immediately. 3.
