7.1 .D. - Page 51 <br /> Exhibit "C" <br /> Inspection and Maintenance Checklist <br /> Manufactured Stormwater Treatment Measure Maintenance Plan for <br /> 601 Main Street, Redwood City <br /> October 2013 <br /> Manufactured Stormwater Treatment Measures are PROPRIETARY treatment devices that <br /> tend to be installed below ground and operate using some type of proprietary filter media, <br /> hydrodynamic separation, or sedimentation and screening. Common examples of <br /> manufactured treatment measures include manufactured media filters, inlet filters or drain <br /> inserts, oil/water separators and hydrodynamic separators. In August 2004, the Regional Water <br /> Board's Executive OFfice wrote a letter stating that a project relying on inlet filters or oil/water <br /> separators as the sole treatment measure would be unlikely to meet the maximum extent <br /> practicable standard of the National Polutant Discharge Elimination System Permit. See the <br /> Countywide C.3 Technical Guidance (vwvw.flowstobav.orq) for more information. <br /> Project Address: 601 Main Street, Redwood Citv <br /> Assessor's Parcel No.: <br /> Property Owner: Lennar MultiFamilv Investors Phone No.: (415) 344-8841 <br /> Designated Contact: Peter Schellinqer Phone No.:(415) 344-8841 <br /> Mailing Address: 100 Pine Street, Suite 2260, San Francisco, CA <br /> 94111 <br /> The property contains 2 Contech StormFilter Units located as described below and <br /> as shown in the attached site plan'. <br /> • Unit 1 is located inside the parking garage along Bradford <br /> Street <br /> • Unit 2 is located inside the parking garage along Marshall <br /> Street <br /> I.
