Erosion Control

Just before construction begins and through the life of the project, the city contractor will install filtration bags inside storm drains and place bags of wood chips outside storm drains located within the project area. They may also install fencing to keep sediment and debris contained on the work site. This helps to prevent or reduce debris entering the sewer/stormwater system, to protect water quality and prevent blockages and backups.
