SCOTT <br /> f. Information regarding the proposed secondary upland seed mix is further <br /> detailed in Exhibit F. The proposed cottonwood sapling plan is to plant <br /> one tree per acre in those dry land areas left after pond construction. As <br /> discussed above, the size of the proposed recreational pond is 36 acres, <br /> Leaving 22 acres of land; accordingly, at minimum of 22 cottonwood <br /> saplings will be planted throughout the site. <br /> 4. Exhibit G - Water Information; Rule 6.4.7 <br /> a. The issues raised here are addressed in response to item 2(f). <br /> b. Scott Contracting commits to providing proof of all required DWR permits <br /> prior to conducting mining operations. Alternatively if a dewatering <br /> permit is obtained and the gravel well pond permit is delayed, Scott <br /> Contracting commits it will retain enough material on site to backfill and <br /> all areas with exposed groundwater to two feet above the static Ground <br /> Water level. <br /> c. The attached, updated wetlands report, prepared by SGM (Exhibit C), <br /> addresses the size and depth of the hydrologic cone of the depression that <br /> will be created by dewatering operations, and confirms that no wetlands <br /> on neighboring properties will be injured as a result of the dewatering <br /> operations. <br /> d. The USACE regulates the discharge or dredging of sediment into wetlands, <br /> including activities such as the commercial development of gravel <br /> resources, however wetlands supported entirely by irrigation water <br /> (a.k.a. agriculturally induced wetlands) are not regulated. <br /> The eastern portion of the Parcel does not contain jurisdictional waters <br /> or wetlands, and development can proceed in this area without further <br /> Section 404 permitting considerations. SGM's site investigation completed <br /> on July 17, 2019 will be formalized in a wetland delineation report to <br /> provide confirmation of regulatory compliance, once development of the <br /> gravel operation is approved and the precise extent and nature of the <br /> initial development activities are determined. In addition, groundwater <br /> pumping is not regulated by the USACE, nor are indirect impacts to <br /> wetlands due to an adjacent pit dewatering operation (USACE, T. Morse, <br /> pers. comm.). Therefore, although initial gravel pit dewatering in the <br /> eastern portion of the property will depresses groundwater in adjacent <br /> wetlands and contribute to a loss of wetland conditions, that activity is <br /> not regulated and does not require a permit under Section 404. <br /> Dewatering permits from the Colorado Department of Public Health and <br /> Environment (CDPHE) -Water Quality Control Division (WQCD) and the <br /> Division of Water Resources (DWR) are required for dewatering <br /> operations. <br />
