City of Pleasanton P6621.002.000 Storm Damaged Repair Sites March 7, 2024 PROPOSAL FOR ENGINEERING DESIGN SERVICES Latest Revision March 25, 2024 Page 5 • Anticipated schedule for project construction; and • Information regarding post-construction stormwater management based on the project’s stormwater management plan. WRA will act as the agent during the permitting process. Typically, the Corps may request a site visit to discuss the proposed project and potential impacts on areas within their jurisdiction. Section 401 Water Quality Certification/ Waste Discharge Requirements – Regional Water Quality Control Board (RWQCB) Based on a preliminary review of project site aerials, streams and drainages which may be RWQCB-jurisdictional are present with the storm repair project sites. Should the features meet the criteria for Corps-jurisdiction, then a Section 401 Water Quality Certification will be required. If site features are not Corps-jurisdictional, then the RWQCB regulates fill placed in wetlands and other waters via Waste Discharge Requirements (WDR). The contents of a WDR application are similar to those required by a Section 401 Water Quality Certification, with some processing modifications: the absence of federal permit requirements means that the permit must be taken to the Water Board for approval, a process which typically requires additional attention and scrutiny on the application by RWQCB staff. WRA will act as the agent for the City to the RWQCB. Information required for both the 401 Certification and the WDR Application includes: • Basic notification requirements as to site location; project description; and type and amount of fill in potentially jurisdictional areas; • Appropriate plan and cross-sectional view figures that show proposed impacts to jurisdictional areas; • Delineation map based on a site visit conducted by WRA staff; • A watershed profile describing the current status and trends of aquatic resources within the watershed; • Proposed compensatory mitigation for any loss of jurisdictional areas; • Alternatives analysis documenting rationale for why impacts to the wetland cannot be avoided; • Anticipated schedule for project construction; • Information regarding post-construction stormwater management based on the project’s stormwater management plan; and • Certified Environmental Quality Act documentation (Mitigated Negative Declaration/EIR/ Categorical Exclusion). CDFW Streambed Alteration Agreement CDFW requires any person who may affect the bed or bank of a perennial, intermittent, or ephemeral river, stream, or lake to provide notification via a California Fish and Game Code Section 1602 Lake and Streambed Alteration Agreement (LSAA). The LSAA notification requires completion of an application form and project environmental questionnaire, and inclusion of supplemental data regarding issues covered in the project environmental questionnaire.
