Following are my observations and comments: <br />• Sediment Ponds No. 002, 003, 004, 005, and Sediment Trap A have been removed from <br />service, graded, and topsoiled for seeding. <br />• Drainage Ditches No. lA, 1B, 2Na, 2Nb, 2S, 2526, 2S2c, 2Na, 2Nb, 3N1, 3N2, 3Na, <br />3Sa, 356, 3Sc, 3Sd, 4Na, 4Nb, SNa, SNb, SNc, SSa, and SSb have been removed from <br />service, graded, and topsoiled for seeding. <br />• Drainage Ditches No. 2S2a, 251, 3Na (part), 3Nb, 3Bc, and 3Sb have been left as <br />permanent drainage. <br />• Short new diversion structures have been constructed to provide permanent drainage at <br />the locations shown on the revised MAP 8, Drainage Control Plan. These structures <br />appear adequate for permanent runoff management. <br />MAP 8 has been revised to reflect current (final) topography. The attached <br />photographs document the appearance of most of the reclaimed areas as well as the new <br />diversion structures.
