8.A. - Page 51 enter the storm drain system, the proposed project will not violate any water guality standards or waste c&scharge reguirements Purthermore, the DTPP program EIR (pp. 10-23 through 10-25) concluded that DTPP facilitated development would not result in any significant water guality or storm water drainage impacts. The proposed project is in compliance with all applicable DTPP regulations, and as a resul� no potenfially significant water guality or storm water drainage impacts are anticipated with implementation of this project The project applicant has prepared a Stormwater Management Plan (BDE Architects and Sanc&s, Plan Sheet C-4, 7/31/2013) that inc&cates a mec&a filtration vault system to clean storm water at the project site. Other data provided by the project engineers include: (I) rainfall intensity and peak flow calculafions per Redwood City design cntena, (2) worksheets and cross secfions for accommodafing peak flows within a proposed 33-inch- c&ameter storm drain to replace the erisfing 24-inch drain underTefferson and Peterans, and(3) a map illustrafing the project drainage area �d erisfing drainage facilities, incluc&ng a 24-inch storm drain proposed to be re-routed on the project site. All of the above storm water data and components are subject to review and approval by the City. b. The City ofRedwood City does not rely on groundwater as a water supply source. Implementation of the proposed project will not reguire substantial amounts of water such that it would result in a substantially depleted groundwater supplies. Therefore, the proposed project will not interfere substantially with groundwater recharge such that there would be a net deficit in aguifer volume or a lowenng of the local groundwater table level. Purthermore, the DTPP program EIR (p. 10-25) concluded that DTPP facilitated development would not result in any significantgroundwater impacts The proposed projectis in compliance with all applicable DTPP regulations, and as a resul� no potentially significantgroundwater impacts are anficipated with implementation of the project c. & d The proposed project will neither change the amount of surface water nor change the currents, course, or c&rection of water movements in any surface water. As a resul� project implementafion will not substanfially alter the existing drainage pattem of the site orDTPP area. Purthermore, the proposed site does not contain a stream or nver; therefore, no associated impacts will occur with respect to substanfial erosion or siltation on- or off-site. Moreover, the proposed project will not substantially alter the existing drainage patZern of the site so as to substantially increase the rate or amount of surface runoff in a manner which would result in flooc&ng on- or off- site. The DTPP program EIR (pp. 10-23 and 10-24) concluded thatDTPP facilitated development would not result in any significant storm drainage impacts The proposed project is in compliance with all applicable DTPP regulafions, and as a resul� no potentially significant storm drainage impacts are anticipated with implementation of this project f. YVith implementafion of the San Mateo Countywide Stormwater Pollufion Prevenfion Plan (SYVPPP) as part of both the NPDES permit program and DTPP program EIR Mitigation 16-3,project construcfion will result in a less-than- significant degradation of erisfing water guality. Purthermore, operation of the proposed project will notgenerate any foreseen uses that would substantially degrade water guality. The proposed project is in compliance with all applicable DTPP regulations, and as a resul� no adc&�tional water guality impacts are anticipated with implementation of this project The project is expected to gualify for a 75 percent exemption under Special Project Category "C"of the San Mateo County YVater Pollution Prevenfion Program, which means that the project would be 75 percent exempt(in storm drainage volume)from County low impact development(I,ID) reguirements because the project: (I) is within '/- mile of an existing transit hub (Caltrain/SamTrans), (2) includes no surface parin�ng, and(3)has a minimum density of 100 dwelling units per acre (project density would be 193 units per acre). The project would include 1,200 sguare feet of LID area to treat the remaining 25 percent of storm drainage volume. (Plan Sheets L-1.0 �d C-4) This exemption and the LID measures are subject to City review and approval. g. &h. The project site is not located in a Special Plood Hazard Area as defined by the Pederal Emergency Management Agency (FEMA) National Plood Insurance Program (NPIP), which means that the site is not subject to extensive damage from a one percent chance (100-year)flood However, almost the entire project site is located in Zone X on its PEMA Plood Insurance Rate Map (FIRM), which means the site: (I) is subject to a 500-year flood or a flood that has a 0.2 percent chance of occurring in any one year, or(2) is subject to a 100-year flood with average depths of less than one foot or with drainage areas less than one sguare mile, or (3) is protected by levees from the 100- year flood (FEMA PIRMMap Number 06081 C0301 E, Effective Date October 16, 2012) Accorc&ng to the DTPP program EIR (p. 10-25), as part of the City's involvement in the NFIP, all new developments within the 500-year flood zone are reguired to meet specific flood damage avoidance reguirements, for example, raising the elevation of habitable space above anticipated flood heights or creating structures that allow flood waters to pass through lower level ofbuilc&ngs(such as the project's proposed parin�ng basement). Also, the City's Drainage Guidelines for Commercial Development reguire post-development storm water c&scharge to be egual to or less than pre-development c&scharge and the project to detain from between the projected 10-year 16
