Saticoy & Wells Community Plan & Development ... - City Of Ventura

Saticoy & Wells Community Plan and Code EIRSection 4.8 Hydrology and Water QualityAction 11.5.2Make use of existing barrancas for drainage, and utilize other naturalistic featuressuch as bioswales, ponds, and wetlands to capture and treat runoff, decreasingflooding, and recharge groundwater. Comply, at a minimum, with the currentmunicipal National Pollutant Discharge Elimination System requirements forpeak flow, stormwater quality, and runoff volume and hydromodification.Policy 11A and Actions 11.1.1, 11.1.2 and 11.1.6 are further discussed in Section 4.4, BiologicalResources.In addition to infill development in already urbanized areas in the Project Area, several largeagricultural parcels, including the UC Hansen site, the Parklands site, the Broome site, theAldea Hermosa site, and Citrus Place, could be developed under the Project. Development ofthese properties would be expected to reduce erosion and sedimentation, but mayincrementally reduce percolation and increase urban pollutants. Installation of water qualityBMPs in conjunction with new development, as required by the Ventura County SQUIMP (asdiscussed above), would mitigate potential urban runoff pollutants. In many instances,replacement of older development with new development built in accordance with currentrunoff and water quality control standards may reduce contaminants entering surface waterand groundwater. Impacts to water quality as a result of infill and new development facilitatedunder the Project would be less than significant.Mitigation Measures. Implementation of existing and proposed policies and actions, incombination with existing regulations, would reduce water quality impacts to a less thansignificant level. Mitigation is not required.Significance After Mitigation. Impacts would be less than significant withoutmitigation.c. Cumulative Impacts. Continued development in the Project Area will increase theamount of impervious surfaces that in turn will concentrate flow, and increase volume andvelocity of runoff. As discussed in Section 3.0, Environmental Setting, planned cumulativedevelopment associated with growth forecasts from the 2005 General Plan in the City ofVentura would add about 8,300 dwelling units, as well as about 1.2 million square feet of retaildevelopment, 1.2 million square feet of office development, 2.2 million square feet of industrialdevelopment, and 530,000 square feet of hotel development. Additional developmentfacilitated by the 2005 General Plan may also adversely affect the quality of ground and surfacewater by increasing the number and density of vehicles, people, and commercialestablishments. However, 2005 General Plan Policy 3C requires the City to maximize use ofland in the city before considering expansion. As described in the 2005 General Plan FEIR, this“infill first” approach would reduce impacts to hydrology and water quality to a less thansignificant level. Development facilitated under the Project would be consistent with the 2005General Plan. In addition, new development would be subject to regulatory requirements towhich existing development was not subject. As all development in the City, including theProject Area, would be subject to the SQUIMP, the NDPES permit and 2005 General Planpolicies and actions, cumulative water quality, recharge and stormwater infrastructure impactswould not be significant.4.8-15City of Ventura
