7.1.C. - Page 49 <br /> Exhibit C - Inspection and Maintenance Checklist <br /> Manufactured Stormwater Treatment Measure Maintenance Plan for <br /> Palacio Apartments <br /> September 2014 <br /> Manufactured Stormwater Treatment Measures are PROPRIETARY treatment devices that tend to <br /> be installed below ground and operate using some type of proprietary filter media, hydrodynamic <br /> separation, or sedimentation and screening. Common examples of manufactured treatment <br /> measures include manufactured media filters, inlet filters or drain inserts, oil /water separators and <br /> hydrodynamic separators. In August 2004, the Regional Water Board's Executive Office wrote a <br /> letter stating that a project relying on inlet filters or oil /water separators as the sole treatment <br /> measure would be unlikely to meet the maximum extent practicable standard of the National <br /> Polutant Discharge Elimination System Permit. See the Countywide C.3 Technical Guidance <br /> (www.flowstobay.orq) for more information. <br /> Project Address: 488 Winslow Street , Redwood City, CA <br /> Assessor's Parcel No.: 052 - 334 -060, 052 - 334 -070, 052 - 334 - 080,052- 334 -130, & 140 <br /> Property Owner: Acclaim Properties Phone No.: 650 - 324 -9400 <br /> Designated Contact: Mark Johnson Phone No.: 650- 324 -9439 <br /> Mailing Address: 125 Willow Road, Menlo Park, CA 94025 <br /> The property contains 2 , Contech StormFilter located as described below and as shown <br /> in the attached site plan'. <br /> • Stormwater Treatment Unit No.1 is a catchbasin unit located at the Southerly end of the <br /> property within the driveway. <br /> • Stormwater Treatment Unit No.2 is a manhole unit located at the Northerly corner of the <br /> property . <br /> • <br /> Routine Maintenance Activities <br /> The principal maintenance objective is to prevent sediment buildup and clogging, which <br /> reduces pollutant removal efficiency and may lead to failure of the manufactured treatment <br /> measure.
