Page 17 6.4.5 EXHIBIT E - Reclamation Plan level of the basins, will be graded to 3H:1V, or flatter. Lands below 10.0± feet from the anticipated final water level of the basins will also be graded to 3H:1V, or flatter, unless 2H:1V slopes are otherwise approved by subsequent permit revision. Naturally occurring or previously established slopes may exceed 2H:1V where not otherwise affected by extraction activities and may not be altered as part of reclamation unless necessary to facilitate the reclamation of affected lands. All affected lands between the extraction limits and remaining above the anticipated high-water mark of the basins will be capped with a minimum of six (6.0±) inches of soil, as supported by Exhibit I & J - Soils and Vegetation Information. Timing and use of soil are detailed further under Exhibit I & J - Soils and Vegetation Information and Exhibit L - Reclamation Costs. Where compacted lands exist, and are to be revegetated, those locations will be ripped prior to re- soil application. There are no known areas of compaction at the time of this application which would require such activity; and ripping remains a contingency of the application. The final land configuration will ultimately result in two (2) reservoir basins totaling 203.61± surface acres, with a static water elevation surface area of 187.66± acres (refer to Exhibit F: Reclamation Map). The balance of unoccupied affected lands above the anticipated static water level will be stabilized where necessary utilizing the seed mixture as shown under Exhibit L - Table L-l: Primary/Preferred Revegetation Seed Mixture. Lands not otherwise occupied for developed water resources will be later developed to the highest possible end-use, and will likely comprise a mixed use which may include other general agricultural uses as well as light residential, commercial or industrial uses. The Primary Revegetation Seed Mixture, combines a thoughtful mingling of predominantly native grasses of diverse height, form, color and function, to assure that the reclaimed site can provide for a multiple-use benefit. Should post resource recovery land development be deferred, or even negated, all affected land remaining above the anticipated final water level of the resulting ponds will be stabilized with a diverse and durable cover of predominantly native grasses. This is compatible with, and an improvement over the diminished lands located in the floodplain of the two rivers, and area monocultures of residential bluegrass lawns and surrounding cropped land. 'Generally, warm and cool seed mixtures can be treated in a myriad of ways. In Table L-1 this distinction is indicated in the column labelled "C/W". Cool season mixtures are often planted in the fall and warm in the spring, however, 3 Adequacy Item 33 VARRA COMPANIES, INC.
