Project Impacts and Mitigation MeasuresImpact U-1Development facilitated by the Project would increase waterdemand by a net increase of approximately 1,014 acre feet peryear (AFY). The total estimated water available from LakeCasitas, the Ventura River diversion, and groundwater basins is28,000 AFY, which is sufficient to meet these projected demandincreases. Therefore, water supply impacts would be Class III,less than significant.Development facilitated by the Project would generate a water demand increase estimated at1,014 AFY, as indicated in Table 4.14-6. Overall projected water demand for 2018 is 22,969 AFYand projected water supply is 29,900 AFY (City of San Buenaventura 2008 Biennial WaterSupply Report). The 2018 demand is projected to be 23,983 AFY, which is within the projectedsupply.Agricultural areas within the Project Area are not served by the City water system, but doutilize water from private wells drawing from the same groundwater basin as the City. Whenthese lands are taken out of agricultural production, the available water supply that can beextracted from existing City wells or new City wells increases. Although water use variesdepending on such conditions as crop type and soil characteristics, the average agriculturalirrigation use is assumed to be 2.5 feet per year (30 inches) (2005 General Plan). Within theProject Area, 160 acres of lands in agricultural production are slated for conversion to urbanuses. Using the equation 2.5 AFY x 160-acres, the conversion of 160 acres would yield a 400-AFY water credit. This would create an additional source of water available for urban demandin the City.4.14-11City of Ventura

In addition,developers would be responsible for constructing all local on and off-site distributionimprovements necessary to bring the particular development up to current standards. Wheresubstantial intensification is anticipated, upgrades to older water distribution infrastructure toimprove pressure and fire flow may be required.Mitigation Measures. Impacts would be less than significant; therefore, mitigation is notrequired. Continued implementation of the following 2005 General Plan policies and actionswould further reduce water demand.Policy 5AAction 5.1Action 5.3Policy 5BFollow an approach that contributes to resource conservation.Require low flow fixtures, leak repair, and drought tolerant landscaping(native species if possible), plus emerging water conservation techniques,such as reclamation, as they become available.Demonstrate low water use techniques at community gardens and cityownedfacilities.Improve services in ways that respect and even benefit the environment.Significance After Mitigation. Impacts related to water supply and reliability would beless than significant without mitigation.Impact U-2New development facilitated by the Project would increasewastewater generation. However, projected future wastewaterflows would remain within the capacity of the City treatmentplant. Impacts are Class III, less than significant.4.14-12City of Ventura
