EVALUATION OF SEAWATER DESALINATION PROJECTS<br />
PROPOSED FOR THE MONTEREY PENINSULA<br />
6 Regional Water Supply Considerations<br />
In this section, each <strong>of</strong> the four projects is qualitatively evaluated on its potential to:<br />
• Provide regional solutions,<br />
• Expand to meet future needs,<br />
• Impede or preclude future projects, and<br />
• Impact disadvantaged communities.<br />
Table 10 provides a brief summary <strong>of</strong> each project’s size and the areas served.<br />

6.1 Coastal Water Project (CWP)<br />
Currently, the Coastal Water Project (CWP) is progressing as the Basic CWP, which will<br />
provide enough desalinated water to comply with SWRCB Order No. 95-10. A larger<br />
regional project providing an additional 8,542 acre-feet per year to meet planned growth on<br />
the Monterey Peninsula and to supply water to Northern Monterey County, Castroville, and<br />
Marina has been studied. An option is under consideration by California American Water<br />
(CAW) as part <strong>of</strong> the CPUC environmental review process to upsize the CWP conveyance<br />
