SNO Road and Street Maintenance <br />i Avoid wet cleaning or flushing of street, and utilize dry methods where possible. <br />i Consider increasing sweeping frequency based on factors such as traffic volume, land use, <br />field observations of sediment and trash accumulation, proximity to water courses, etc. For <br />example; <br />Increase the sweeping frequency for streets with high pollutant loadings, especially in <br />high traffic and industrial areas, <br />Increase the sweeping frequency just before the wet season to remove sediments <br />accumulated during the summer. <br />Increase the sweeping frequency for streets in special problem areas such as special <br />events, high litter or erosion zones. <br />i Maintain cleaning equipment in good working condition and purchase replacement <br />equipment as needed. Old sweepers should be replaced with new technologically advanced <br />sweepers (preferably regenerative air sweepers) that maximize pollutant removal, <br />i Operate sweepers at manufacturer requested optimal speed levels to increase effectiveness. <br />i To increase sweeping effectiveness consider the following; <br />Institute aparking policy to restrict parking in problematic areas during periods of street <br />sweeping, <br />Post permanent street sweeping signs in problematic areas; use temporary signs if <br />installation of permanent signs is not possible. <br />- Develop and distribute flyers notifying residents of street sweeping schedules. <br />i Regularly inspect vehicles and equipment forleaks, and repair immediately, <br />i If available use vacuum or regenerative air sweepers inthe high sediment and trash areas <br />(typically industrial/commercial). <br />i Keep accurate logs of the number of curb -miles swept and the amount of waste collected. <br />i Dispose of street sweeping debris and dirt at a landfill. <br />i Do not store swept material alongthe side of the street or near a storm drain inlet. <br />i Keep debris storage to a minimum during the wet season or make sure debris piles are <br />contained (e.g. bybermingthe area) or covered (e.g. with tarps or permanent covers). <br />Street Repair and Maintenance <br />Pavement marking <br />i Schedule pavement marlang activities for dry weather. <br />2 of 9 California Stormwater BMP Handbook January 2003 <br />Municipal <br />www.cabmphandbooks.com <br />
