high, 450' long earthen berm will be placed along the southwest border of the proposed area as this is <br />the lowest elevation in the whole quarry. The overburden and rubble berm will be seeded with native <br />seed to prevent runoff and add to the view shed to the southwest. The current stormwater plan has <br />worked since 1997 with no problems, even during the 500 year flood of September 2013, in the existing <br />quarry DRMS M-1997-065 and will continue to work for the proposed amendment. <br />The existing access road follows the eastern boundary of the amended area. The road is elevated above <br />the amended area and western edge of the road has a steep dip of about 60 degrees toward the <br />proposed quarry. The composition of the road/canal bank is a mixture of stone and clay that was <br />excavated from the east side of the road, for the construction of the canal and access road, and has had <br />over 100 years to compact to it's present state. The northern tip of the eastern edge of the amended <br />area is 82.96 feet from the western side of the 30 foot wide road. The eastern edge at the southern tip <br />of the amended area is 170 feet from the western edge of the access road. A notarized and signed <br />Structure Agreement form, from WRCC who own the Poudre Valley Canal, is in the packet. <br />The grade of the eastern wall of the amended area running parallel to the access road will maintain the <br />60 degree dip of the access road bank all the way to the floor of the quarry to ensure the stability of the <br />canal/access road. <br />The proposed affected land total will be increased to 46.18 acres. <br />Additional hauls roads on the amended area will generally follow the path of the "old driveway" to the <br />south as indicated on the new Mining Plan Map. The "old driveway" from the southeastern tip of the <br />amended area to the main access road will not be used.
