Erosion & Sediment Control

Stormwater runoff from construction sites can erode disturbed soils, carry it off-site and contribute significant amounts of sediment (soil) to the surrounding environment.

In an effort to protect and enhance the integrity of Coquitlam’s drainage system and aquatic environments, including our creeks and rivers, the City of Coquitlam has adopted sustainable development practices for all construction activities.  

The Stream and Drainage System Protection Bylaw No. 3447, 2001 prohibits any material, including sediment, from being discharged directly or indirectly to the drainage system, which includes any creeks, streams or rivers as well as the City’s drainage infrastructure.  It sets forth mandatory standards for onsite erosion and sediment control, including planning, maintenance, operation and inspection. The Bylaw also prohibits discharging stormwater from a site that carries a sediment load greater than 75mg/L TSS, the permissible maximum discharge level for Total Suspended Solids, or a pH value outside of the range 6.5 to 8.0.
