Erosion Control

Erosion control is important to prevent soil, sediment, and cement from entering the sewer and stormwater drainage systems and our rivers and streams. Erosion control helps prevent sewer blockages, basement sewer backups, damage to properties, and loss of wildlife habitat.

Before construction begins and throughout the project, crews will install various measures to prevent erosion of soil, sediment, and cement. These measures include installing filtration bags inside storm drains and placing bags of wood chips outside storm drains within the project area. Crews may also install fencing to contain sediment and debris on the work site.
