o Dry Wells o Cistern b. A WQMP shall be prepared, maintained, and updated as needed to satisfy the requirements of the adopted NPDES program. The plan shall incorporate water quality measures for all improved phases of the project. (Impact 4.6-1 and Impact 4.6-3) MM4.6-2 Prior to issuance of grading permits for future development projects in the Transit Zoning Code (SD 84A and SD 84B) area, applicants shall submit site -specific Hydrology and Hydraulic Studies to the Public Works Department for review and approval. If existing facilities are not adequate to handle runoff that may be generated by the proposed development, then the applicant shall propose feasible remedies to assure that adequate drainage facilities will be available prior to issuance of occupancy permits. The applicant may propose storm drain improvements to be constructed in order to meet project needs. If necessary storm drain upgrades cannot be implemented prior to issuance of occupancy permits, on site detention facilities or other methods acceptable to the City shall be included with new development projects to ensure that post -construction runoff does not exceed pre -development quantities. (Impact 4.6-4) MM4.6-3 During the design of individual projects, applicants shall minimize impervious area by incorporating landscaped areas over substantial portions of a proposed project area. Furthermore, impervious areas shall be directly connected to landscaped areas or bioretention facilities to promote filtration and infiltration of stormwater. (Impact 4.6-4) MM4.6-4 During the design of individual projects, applicants shall control structural source through storm drain stenciling and signage, coverage of trash area to minimize direct precipitation, efficient irrigation to minimize runoff into stormwater conveyance system, slope and channel protection to decrease potentials for erosions of slopes, and use of deep-rooted, drought tolerant plant species for erosion control. (Impact 4.6-4) Project Analysis and Conclusion The City determined that impacts related to within a 100-year flood hazard area, flood inundation area, inundation from the Prado Dam, a seiche, tsunami, or mudflow would have no impacts (DEIR Section 4.6-3). Impacts related to interference with groundwater recharge (Impact 4.5-1), alteration to existing drainage patterns (Impact 4.6-3) and increased downstream flooding (Impact 4.6-4) were less than significant with the implementation of mitigation measures. The proposed adoption of the text regulations identified in Table 1 — Current and Proposed Text Regulations would not require preparation of specific development projects, introduce new land uses nor increase the intensity the existing uses. The new regulations would require liquid or solid wastes discharged from future development projects be properly treated and would therefore not pollute or contaminate any water courses or groundwater. Any future development within the TZC area requiring discretionary action would continue to be subject to a project -level CEQA review at the time an application is filed for an individual project. Mitigation measures MM4.6-1 through MM4.64 would continue to apply. Therefore, the project does not trigger new hydrology and water quality impacts requiring the preparation of a subsequent or supplemental EIR. In addition, compliance with the existing regulations and proposed amendments will assure that potential impacts are not exacerbated. Therefore, there would be no new or more severe significant impacts to hydrology and water quality. 5.7 LAND USE January 2025 35 Environmental Analysis
