The DTPP Final EIR found that individual projects developed within the DTPP would include replacing existing <br />developed areas with new development, and although residential and commercial densities would increase, there <br />would be minimal difference between the DTPP buildout scenario and existing conditions in terms of stormwater <br />runoff. No areawide drainage improvements were anticipated, and the DTPP was found to potentially result in a <br />reduction of stormwater runoff, due to increased landscaping and City’s runoff retention requirements. As a result, <br />impacts on storm drainage infrastructure were determined to be less than significant. The DTPP Plan-Wide <br />Amendments found that the stormwater drainage system impacted by new private development as a result of the <br />proposed DTPP Plan-Wide Amendments (including but not limited to proposed stormwater culvert realignment) <br />would lead to capacity-enhancing improvements. While there were new potential impacts compared, they were <br />deemed to be less than significant after mitigation. Mitigation Measure UT-1d requires that the stormwater system <br />upgrade demands be evaluated by a licensed engineer and that each development in the amended DTPP area <br />demonstrate it either had sufficient capacity or would undertake the improvements necessary to meet their added <br />demand. <br />ATTY/RESO.0074/CC RESO 847 WOODSIDE (CEQA) - EXHIBIT 1 - CEQA CONSISTENCY CHECKLIST <br />REV: 10-23-24 VR <br /> <br />Page 80 of 135
