The slope nrar the water line may be constructed <br />with a considerably fl<+tter slope to create and/or replace <br />wetlands. A minimum of ]2" of topsoil will be placed along <br />the perimeter of the pond. All areas above the water <br />surface to a minimum of 3 feet below the surface of the <br />water will receive topsu+l. <br />B. Moderate Disturbance Areas <br />1. Backfilling operations will be minimal due to the depth of <br />the excavation and the small quantity of overburden and/or <br />unsuitable material expected to be encountered during <br />• gravel extraction. After the e?:is[ing gravel reserves are <br />mined, unsuitable materials encountered during mining would <br />be transported directly to the backfill areas. <br />Once an area is sufficiently mined, any unsuitable material <br />that had been stockpiled would also be transported to the <br />backfill area for disposal. <br />In addition to initial shaping of the pond perimeters with <br />the unsuitable materials, unsuitable material may be <br />utilized to fill some excavated areas completely. This <br />will be dependent upon the amount of unsuitable material <br />encountered during mining operations. <br />From the project access at the northeast corner of the <br />project, the interior access road for Phase I will enter <br />the pit south of the site access. This road will be <br />relocated as the excavation expands to the west. The <br />general location of the Phase I interior roads is shown on <br />the attached map. when [he Phase I excavation is nearing <br />completion, this road will be permanently located approxi- <br />mately where shown on the map. <br />A secondary road, as shown, may be constructed along the <br />south boundary to allow access to the Grant/winograsky <br />• property. This southern secondary access will eliminate <br />truck traffic entering U.S. Highway 40 to gain access to <br />the Delta Electric property for use of their scales. <br />Duckels Construction, Inc. dba Yampa Aggregates <br />41230 Routt County Rd. ?1129, Steamboat Springs, Colorado i304S7 <br />
