• • Site Management Under the Grading, Drainage, and Erosion Control Plan notes (Attachment 5), Item 2 indicates that 4 inches of top soil and sod or seed be placed on disturbed, unpaved areas. This should say that 4 inches of topsoil would be thoroughly worked (tilled) into the soil. Notes should also say that no soil shall be imported or exported from the site without City approval. The Storm Water Pollution Prevention Plan (Attachment 6) notes, item 9 states that sediment laden water must be discharged to a sediment basin whenever possible, if not possible it must be treated with appropriate BMP's. This should include a statement that the City will be notified when storm water must be treated with alternative BMP,s and agree to them. Item 11 in the notes states that external washing of construction vehicles must be limited to a defined area of the site. This site should be identified on the plan, or at pre- construction time, and include the internal washing of cement carriers. Sequencing under the notes section (item 2) indicates the construction of a rock construction entrance. The plan should include additional stockpile of rock on site to top dress the entrance pad when the pad becomes filled up. In addition, in the notes concerning sequencing, the sediment ponds are constructed early. The ponds should be dug with minimum compaction equipment and fenced off to further traffic during construction. Item 15 under notes #2 should include a statement of restoring soil to pre- construction soil densities. Tilling, plowing, disking, etc can do this. Options: 1. Approve Mike Vaughan Subdivision 2.
