Findings and Statements Required by the California Environmental Quality Act <br />Redwood City DTPP Plan-Wide Amendments 17 ESA / 202100421.01 <br />Subsequent Environmental Impact Report May 2023 <br />Impact UT-6: Implementation of the DTPP Plan-Wide Amendments would not violate any <br />water quality standards or waste discharge requirements or otherwise substantially degrade <br />surface or groundwater quality. <br />The proposed DTPP Plan-Wide Amendments would allow for development on previously <br />developed land, and the change in impervious surfaces would be negligible. Further, the added <br />landscaping would provide additional pervious surfaces. Potential future relocation and alteration of <br />approximately of Arroyo Ojo, a small creek that is otherwise completely culver ted would not be <br />anticipated to result in violation of water quality standards or waste discharge requirements or <br />otherwise substantially degrade surface or groundwater quality. Compliance with SWPPP <br />regulations would be sufficient to address impacts from the proposed DTPP Plan-Wide <br />Amendments as they relate to water quality issues as a result of polluted runoff from future ground <br />disturbance. The proposed DTPP Plan-Wide Amendments would not result in new or more severe <br />impacts than the impacts identified in the DTPP Final EIR. Therefore, the impact would be less <br />than significant. (Draft SEIR, pp. 10-39 to 10-40.) <br />Impact UT-7: Implementation of the DTPP Plan-Wide Amendments would not substantially <br />decrease groundwater supplies or interfere substantially with groundwater recharge such <br />that the project may impede sustainable groundwater management of the basin. <br />The proposed DTPP Plan-Wide Amendments do not propose the use of groundwater <br />supply, and would redevelop an already urbanized area so that the amount of impervious surfaces <br />would remain essentially the same. For these reasons, the impacts on groundwater resulting from <br />the proposed DTPP Plan-Wide Amendments would be similar to those identified in the DTPP Final <br />EIR and would not result in new or more severe impacts. The impact would be less than significant. <br />(Draft SEIR, p. 10-40.) <br />Impact UT-9: Implementation of the DTPP Plan-Wide Amendments would not result in flood <br />hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation. <br />The amended DTPP area is not within a tsunami zone or in an area at risk of inundation <br />from a seiche. Therefore, tsunami and seiche related impacts would be less than significant. Further, <br />the amended DTPP area is not within the 100-year flood zone, so flood-related risks would also be <br />less than significant. (Draft SEIR, pp. 10-42.) <br />Impact UT-10: Implementation of the DTPP Plan-Wide Amendments would not conflict with <br />or obstruct implementation of a water quality control plan or sustainable groundwater <br />management plan. <br />The proposed DTPP Plan-Wide Amendments would not use groundwater supply, and <br />future developments would not increase the amount of impervious surfaces. For these reasons, and <br />because the proposed DTPP Plan-Wide Amendments would subject to applicable City, County, <br />and RWQCB requirements (including preparation of a SWPPP), the potential impacts from the <br />proposed DTPP Plan-Wide Amendments to water quality control plans and sustainable <br />groundwater management plans would not result in new or more severe impacts than what was
