7A Page 24 be served by these utilities) and will comply with all ordinances) statutes and guidelines of these utility providers. The project would not violate any water quality standards or waste discharge requirements, or otherwise degrade water quality, as development would be limited to residential use which restricts discharge of waste. The project would not substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level. The following existing provisions in the R~2 zoning ordinance, which would not change, set minimum standards for pervious area and stormwater requirements, as follows: Sec. 6.11 - Minimum Pervious Area and Storm water Requirements A minimum of forty (40) percent of each lot shall be pervious area, to be composed of landscaping, vegetated open space, or permeable paving materials, consistent with the provisions of Section 32. 12 of the Zoning Ordinance, as that section may be amended from time to time. All development is a/so subject to the requirements of Chapter 27.A (Stormwater Treatment Measures and Maintenance Program) of the Municipal Code, as that chapter may be amended from time to time. Sec. 6. 12 Required Pervious Area in Front Yard A minimum of sixty (60) percent of the area of the front yard shall be pervious area, primarily comprised of pervious landscaped material. For lots less than fifty (50) feet in width) however, a maximum paved area of twenty (20) feet in width for a driveway and parking (from the road to the front setback line) is permitted within the front yard. Area devoted to public sidewalks shall not be included in the calculation. The project would not substantially alter the existing drainage pattern of the site or area or substantially increase the amount of surface runoff. While the project could result in increased densification of residential lots due to the increase in housing units, the proposed code text change will not conflict with Sec. 6.11 and 6.12 above as these provisions would still continue and apply to all lots subject to this ordinance. Therefore, the requirements for pervious surfaces and inclusion of stormwater treatment measures as part of any proposed development will ensure that the addttion of residences on these lots will not substantially alter the drainage pattern of the area or contribute to stormwater runoff which would exceed the capacity of existing drainage systems. In addition) the proposed code amendment would not trigger SWPPP permtt requirements; these would only result from individual projects involving more than one acre. These could result in the future but would be subject to site-specific environmental analysis. The applicable R-2 zoning districts are not located within a flood, tsunami, seiche, or mudflow hazard area. In addition, the analyzed R~2 districts located in Redwood Oaks and West Woodside are within FEMA Zone "e" - "Areas of Minimal Flooding" per the applicable Flood Insurance Rate Map) while the analyzed district located in Friendly Acres is within Zone "8" - "Areas of Moderate Flood Hazard", Therefore, the project would not place housing within a 100-year flood hazard area, would not expose people or structures to significant flood risk as the result of the failure of a levee or dam) and would not place people or structures in an area at risk of seiche, tsunami, or mudflow. 181 City of Redwood City, Planning, Housing and Economic Development Department
