Crews in Spokane Valley have begun sweeping residential areas continue through May.
Drivers and residents can expect to see slow-moving sweeping vehicles between the hours of 7 a.m. and 5 p.m. weekdays until all residential areas have been swept, say city officials.
The trucks will be removing dirt and debris to help prevent clogging of stormwater drainage systems. If drains become clogged, pooled water at the clogged drains can pose a driving hazard. In severe cases, it can result in damage to adjacent properties.
The street sweeping program also helps prevent deterioration of roadways due to standing water, and helps improve air quality by removing excess dust and dirt that can get blown into the air by passing vehicles and breezes.
To help crews complete street sweeping quickly and effectively, residents are encouraged to keep vehicles, trailers and portable basketball hoops out of the right of way during the sweep. It is also important to keep vegetation trimmed back from curbing and out of the right of way and to trim overhanging branches to at least 14 feet above the public street.
Cost of street sweeping is funded primarily by the city's stormwater fund and supplemented by the street fund.
