041 Both proposed amendments have been evaluated against the Locational Criteria from the Land Use Element of Comprehensive Plan, since JPA amendments are also inherently Comprehensive Plan amendments. The proposed Extractive Use expansion complies with nine of 10 criteria, with a "questionable" evaluation on the criterion relating to "Hydrology" impacts. The issue of hydrology is questionable because the criteria states that "Extractive Use" sites should be outside of water supply watersheds. As such, there are very real questions relating to the stringent University Lake Watershed standards and OWASA- commissioned Camp, Dresser and McKee Study regarding runoff from the expanded quarry and relocated asphalt plant and its potential to damage already sensitive water quality. Staff recognizes, however, that there is a balancing "public good" in this case that mitigates this concern. Likewise, these concerns seem to be answered to the - satisfaction of OWASA through their participation in the May 10, 1990 agreement with American Stone, Nello Teer, and Philip and Alice Durham. The proposed Rural Industrial Activity Node complies with 10 of the same criteria, receiving a "Questionable" evaluation on "Hydrology ". Rural Industrial Activity Nodes, according to the Land Use Element, should be located outside of 100 -year flood -prone areas. The floodplain of Phil's Creek, 200 -feet in width, crosses through the site. This water course has already been altered as part of the quarrying operations. Again, however, there is a mitigating circumstance. The diversion of Phil's Creek is in fact a "fait accompli", and the expansion of the quarry will not further negatively impact the floodplain area. It is not clear whether the quarry could operate outside of the floodplain, nor is it clear what the net effect on downstream water quality will be in the short -run. As noted previously, environmental review procedures would apply to an expanded quarry. Also, a full environmental impact statement would be required at the time of special use permit consideration. The applicant would address floodplain impacts at that point. Ultimately, the questions regarding this amendment deal with the public interest and the appropriateness of tradeoffs. Undoubtedly, the creation of an additional water supply source for OWASA will create a future public good, especially since the new quarry reservoir would be coming on -line around the year 2030 as projected water demand would be approaching the capacity of the existing system of reservoirs. In applying the locational criteria for Extractive Use and Rural Industrial Activity Node, HYDROLOGY was the only criterion to receive a "QUESTIONABLE" evaluation. This alone is not 17
