Findings and Statements Required by the California Environmental Quality Act Redwood City Transit District DTPP Amendments 16 ESA / 202100421.00 Subsequent Environmental Impact Report October 2022 Impact UT-7: Implementation of the proposed Transit District DTPP Amendments would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin. The proposed Transit District DTPP Amendments do not propose the use of groundwater supply, and would redevelop an already urbanized area so that the amount of impervious surfaces would remain essentially the same. For these reasons, the impacts on groundwater resulting from the proposed Transit District DTPP Amendments would be similar to those identified in the DTPP Final EIR and would not result in new or more severe impacts. The impact would be less than significant. (Draft SEIR, p. 10-37.) Impact UT-8: Implementation of the proposed Transit District DTPP Amendments would not substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: (i) result in substantial erosion or siltation on- or off-site; (ii) substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site; (iii) create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; (iv) impede or redirect flood flows. Future development under the proposed the Transit District DTPP Amendments would replace existing developed area, and proposed infrastructure improvements would be within existing rights of way and subject to City review, ensuring no substantial changes to drainage patterns. As a result, the impacts from the proposed Transit District DTPP Amendments would be similar to those identified in the DTPP Final EIR and would not result in new or more severe impacts. The impact would be less than significant. (Draft SEIR, p. 10-38.) Impact UT-9: Implementation of the proposed Transit District DTPP Amendments would not result in flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation. The Transit District area is not within a tsunami zone or in an area at risk of inundation from a seiche. Therefore, tsunami and seiche related impacts would be less than significant. Further, the Transit District area is not within the 100-year flood zone, so flood-related risks would also be less than significant. (Draft SEIR, pp. 10-38.) Impact UT-10: Implementation of the proposed Transit District DTPP Amendments would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan. The proposed Transit District DTPP Amendments would not use groundwater supply, and future developments would not increase the amount of impervious surfaces. For these reasons, and because the proposed Transit District DTPP Amendments would subject to applicable City, County, and RWQCB requirements (including preparation of a SWPPP), the potential impacts from the proposed Transit District DTPP Amendments to water quality control plans and sustainable groundwater management plans would not result in new or more severe impacts than what was
