ATTACI~i fEi~IT D: <br />~lARR4 GRAVEL PIT RECLA,~tATION COST ESTIMATE <br />North Area (22 acresl <br />The north clay pit site will be regraded a slope not greater than 3:1. Approximately 24,600 cubic <br />yazds of materials will be moved using only on-site materials. The western stockpile material piles <br />will be le$ untouched on-site for use by City Departments for public projec's. The tAUthwestern <br />drainage will be regraded to drain eastward instead of south. Erosion control fibric will be <br />installed into this new drainage swale.
