12/5/2005 4. Each element of usable open space shall be completely open on at least one (1) side and shall have a clear vertical height of not less than seven (7) feet, and not less than fifty percent (50%) of the total required usable open space shall be unobstructed to the sky; Usable open space shall be improved to support passive or active use by residents. Such open space shall be located on the same lot as the dwelling units for which it is required. The computation of such open space shall include no obstructions other than devices and structures designed to enhance its usability, such as swimming pools, small changing facilities, fountains, planters, benches and landscaping; Where possible, pervious areas set aside as usable open space may also serve as areas for infiltration of stormwater runoff, subject to review and approval by the Engineering and Construction Division. Use of open space areas for stormwater control shall be incorporated into plans to comply with the provisions of Section 32.12 (Stormwater Treatment) of the Zoning Ordinance and Chapter 27 A (Stormwater Treatment and Maintenance Program) of the Municipal Code, as that Section and Chapter, respectively, may be amended from time to time. 5. 6. SECTION 26. That Article 32 (Supplementary Provisions), of the Redwood City Zoning Code is hereby amended to add a new Section 32.12 (Stormwater Treatment) to read in its entirety as follows: Atty/Ord/O rd. 243 111505 "Sec. 32.12 Stormwater Treatment. A. Purpose: The purpose of the requirements set forth in this Section 32.12 is to provide zoning standards that minimize the quantity of runoff and associated pollutants in stormwater runoff from developed sites to creeks, the storm drain system and, ultimately, to the San Francisco Bay. Enhanced stormwater quality can be achieved through reduction of impervious surfaces, the protection of watercourses and riparian vegetation, providing for infiltration of stormwater on-site through vegetation and soils, and with engineered treatment systems. B. Applicability and Compliance with Article 27 A: All new development, additions and reconstruction as outlined below are subject to the provisions of this Section and of Chapter 27A (Stormwater Treatment Measures and Maintenance Program) of the Municipal Code, as that Chapter may be amended from time to time, which outlines technical requirements for stormwater control. Chapter 27 A assures engineering review of all applicable plans for compliance with the requirements of the San Mateo County City/County Nationwide Pollution Discharge Elimination System (NPDES) permit, as approved by the San Francisco Bay Regional Water Quality Control Board. The following development is subject to this Section 32.12 and its applicable subsections: 1130-336 16
