Harbor Boulevard Mixed Use Transit Corridor Plan Findings and Facts in Support of Findings and Statement of Overriding Considerations (3) Potential Impact: Operation of individual development projects would reduce or avoid contamination of stormwater through implementation of the Water Quality Management Plan consistent with the MS4 Permit. Finding: 1. The City hereby makes Finding 1 and determines that this impact is less than significant with the incorporation of mitigation measure 7 -5. Facts in Support of Finding Land use and development types allowed in the project area under the Harbor Corridor Plan would be expected to generate stormwater pollutants, including pollutants of concern as defined by the Environmental Protection Agency. However, priority development projects within the project area would be required to prepare and implement water quality management plans (WQMPs) specifying BMPs to minimize water pollution by the project. Adherence to the BMPs in the WQMP would reduce, prevent, minimize, and /or treat pollutants and prevent degradation of downstream receiving waters. BMPs identified in the WQMP would reduce or avoid contamination of stormwater with sediment and would also reduce or avoid contamination with other pollutants such as pathogens, heavy metals, nutrients, organic compounds, and sediment toxicity. Mitigation Measure 7 -5 includes special provisions for WQMPs prepared for projects in the project area. Upon implementation of regulatory requirements and Mitigation Measure 7 -5, water quality and waste- discharge impacts from operation activities associated with individual development projects accommodated by the Harbor Corridor Plan would be less than significant. Mitigation Measures MM 7 -5 Water Quality Management Plan (WQMP). Prior to the issuance of building permits, project- specific WQMPs shall be submitted for review and approved by the Building Department. The WQMP shall identify the best management practices (BMPs) that will be used on the site to control predictable pollutant runoff. More specifically, the WQMP shall: • Describe the routine and special post- construction BMPs to be used at the proposed development site (including both structural and non - structural measures); • Describe responsibility for the initial implementation and long- term maintenance of the BMPs; • Provide narrative with the graphic materials as necessary to specify the locations of the structural BMPs; • Certify that the project applicant will seek to have the WQMP carried out by all future successors or assigns to the property. 32 July 2014
