The City of Redmond conducts regular street sweeping to provide two main benefits. First, the removal of paper, leaves and other visible debris that collects in gutters can prevent localized flooding during heavy rains.
Second, street sweeping removes metal particles and other hazardous waste products left by passing vehicles. Although they are virtually invisible, these particles can be extremely harmful to fish and other wildlife if they reach our streams and lakes. Street sweeping is an effective method of removing both the large and microscopic pollutants that collect on city streets and serves as one of our Best Management Practices (BMP) to control and improve water quality.
