REGIONAL GROUNDWATER FACILITIES PROJECT <br />FEASIBILITY STUDY <br /> <br /> 26 Zone 7 Water Agency <br />December, 2025 <br /> <br />Notably, the first two criteria, Water Production Capacity and Groundwater Basin Sustainability, are not <br />included in the scoring framework because they function as pass/fail requirements. While only Project <br />Alternatives 2 and 4 satisfy Zone 7’s 7,000 AFY production threshold, all four project alternatives are <br />carried forward into the scoring process for informational and comparison purposes. Scoring definitions <br />were tailored to each of the six weighted categories to ensure transparency and repeatability. Table 7 <br />summarizes the scoring framework for these six categories. <br />Table 7.

Ranking Methodology <br />Each project alternative was first screened against the two pass/fail requirements: water production <br />capacity and groundwater basin sustainability. While only Alternatives 2 and 4 satisfy Zone 7’s 7,000 AFY <br />production target, all four alternatives were considered in this Study. <br />Alternatives passing the initial screen were then scored against the six weighted criteria described in <br />Section 4.1.1. Scores were assigned on a 1–10 scale in accordance with the definitions in Section 4.1.3 and
