Since that <br />inspection the necessary corrective actions have been taken. <br />1. Road Drainage Design - This has been done and should be submitted <br />to your office today by Kiowa Engineering. <br />2. Berm Break Near Shop - Additional material has been placed at t'ie <br />described location and should prevent water from leaving this area. <br />3. Culvert HR-2 - This culvert has been cleaned out. With the <br />changes introduced at the sediment basin this problem should be redu.ed. <br />4. Sediment Basin Edge - The small roadside ridge which was hindering <br />the ability of water to flow into the pond has been graded. Castle is <br />considering installing a more "permanent" outlet system between the <br />safety rocks that would direct the water into the pond more smoothly and <br />would be minimally affected by grading the road which produces the small <br />ridge. <br />5. Sediment Basin Entrance - This area has been reshaped and has peen <br />covered with rip rap so water will flow more smoothly into the uphill <br />side of the first pond. <br />Respectfully, <br />Mark A.
