<br />. <br /> <br />. <br /> <br />. <br /> <br />6) Review Maintenance Procedures <br /> <br />Grit Chambers <br /> <br />The City has several grit <br />chambers. which are devices <br />which act like a drain trap. <br />Rapidly flowing water is <br />captured and slowed by a <br />baffle design which allows <br />some sediment to settle out <br />during low flow rain fall <br />events. The more sediment <br />that collects in the trap the <br />less effective the device <br />becomes in terms of water <br />quality control because <br />succeeding rain events re- <br />suspend trapped material <br />and move it rapidly into the <br />receiving water body. Other <br />maintenance procedures <br />have similar goals. which are <br />to minimize the amount, <br />timing and quantity of sedi- <br />ments that carry pollutants <br />into the cities many water- <br />bodies, <br /> <br />6)Recommendation: <br />Maintain all city sediment collection and water quality <br />control features on a regular schedule. Continue to do <br />timely street sweepings and identify areas most impacted <br />by winter season street runoff. <br /> <br />Method/lmplementation: Implement maintenance proce- <br />dures on selected structures and develop a regular <br />schedule of maintenance, Integrate Best Management <br />Practices (per Water Management Plan) into all City <br />maintenance and repair projects. Monitor grit chambers <br />and sediment ponds for sediment build up and plan a <br />cleaning protocol to ensure effective operation. Identify <br />sediment structures that are a City responsibility, De- <br />velop a test procedure with RCWD engineers or others <br />and provide maintenance on an appropriate schedule, <br />Prioritize areas subject to winter salVsand residue and <br />provide additional buffering for times when street sweep- <br />ing cannot be done in a timely manner such as early <br />Spring thaw seasons. <br /> <br />Costs/resources: May involve additional scheduled staff <br />time and engineering, May involve operations committee <br />review. May involve some staff training, <br /> <br />Relative cost - Low <br />
