relocation of SR 1104 . Beyond that it indicates that the OWASA <br /> quarry reservoir and existing quarry pit will provide flood control <br /> benefits by containing excess stormwater which would be released <br /> later at controlled rates. <br /> In applying the locational criteria for Extractive Use and Rural <br /> Industrial Activity Node, HYDROLOGY was the only criterion to <br /> receive a "QUESTIONABLE" evaluation. This alone is not <br /> justification for a negative recommendation. However, from the <br /> standpoint of the requested amendment, HYDROLOGY is arguably the <br /> single most important locational criterion. It is precisely for <br /> reasons such as this that there are other policy considerations <br /> that come into play in acting on such amendments under the JPA and <br /> Land Use Element. These considerations take into account the public <br /> interest; the health, safety and general welfare of Orange County <br /> citizens. In evaluating these amendments against the criteria, the <br /> "benefits" of guaranteed future water storage capacity - including <br /> safeguards contained in the four-party agreement - seem to outweigh <br /> the reservations associated with expanding the use within the <br /> watershed. <br /> The following water quality and visual mitigation measures <br /> identified in the EIS offer additional safeguards. <br /> Water Ouality <br /> - Minimizing soil exposure by the staging of grading and <br /> revegetation. <br /> - Interception and/or diversion of runoff. <br /> - Application of surface covers. <br /> - Installation of silt fences, erosion screens, and bale <br /> barriers. <br /> - Provision of grass shoulders, grass-lined ditches and <br /> vegetation buffers. <br /> - Maintain a 50 foot buffer between mining operations and <br /> Phil's Creek as required by the existing special use permit. <br /> Visual <br /> - Minimizing roadway cut and fill slopes. <br /> - Roadway alignment following the existing groundline wherever <br /> possible. <br /> - Landscape planting and natural revegetation to the cut and <br /> fill slopes. <br /> - Maintain landscape planting and natural vegetation in the <br /> quarry buffer zones. <br /> - Maintain the 300 foot buffer between extraction areas and <br /> residences and public lands as required by the existing <br /> special use permit. <br /> 19 <br />
