<br />" <br /> <br />ENVIRONMENTAL ANALYSIS <br /> <br />The environmental descriptions and analyses address 16 disci- <br />plines. The disciplines include hydrology; channel stability; water <br />quality; aquatic life; wetlands and riparian aneas; topography, physio- <br />graphy, and geology; soils; vegetation; wildlife; threatened snd <br />endangered species; visual resources; recreation; socioeconomics; <br />transportation; land use; and cultural resources. The environmental <br />analysis process was designed to determine and evaluate potential <br />environmental effects; present findings in a manner that would allow <br />crucial issues to emerge; and develop mitigation. options and cost <br />estimates. for potentially significant impacts. Data used to determine <br />the existing environmental conditions and to estimate future changes <br />were obtained from the engineering analysis and from existing environ- <br />mental Information. A standardized set of environmental evaluation <br />criteria was developed and applied uniformly to all water supply <br />sources. The evaluation criteria were. developed to quantitatively <br />address specific conventional and special-concern issues for each <br />environmental discipline. The quantitative changes were ususlly <br />expressed as changes in acreages or the number of resource features. <br />The quantitative estimates were supplemented with qualitative evalua- <br />tions. Costs of mitigating or compensating potentially significant <br />impacts to each discipline were developed whenever a significant impact <br />was identified. Data for developing the cost estimates were derived <br />from technical literature describing practical snd effective measures. <br /> <br />INSTITUTIONAL ANALYSIS <br /> <br />The institutional charscterization and evaluations of each water <br /> <br />supply source were evaluated in terms of institutional feasibility, <br /> <br /> <br />ease of implementation, and potential side effects. Examples of <br /> <br />potential institutional constraints include requirements for long-term <br /> <br /> <br />managerial coordination between various wster supply entities and <br /> <br /> <br />requirements to obtain approvals for cooperstion among public agencies <br /> <br />10 <br />
