Bioswale Maintenance

What This Service Involves

Bioswales rely on healthy vegetation and unobstructed flow paths to filter pollutants from stormwater. Our crews manage plantings, remove invasive species, clear accumulated sediment, and repair minor erosion within the swale. Work follows the intent of your Ecology-approved facility design and low-impact development standards. We document conditions so your stormwater program can demonstrate ongoing functional performance.

Benefits

Sustained pollutant-removal performance of the facility; invasive species control that protects designed plantings; sediment and erosion management within the swale; documentation supporting low-impact development performance requirements; extended life of the stormwater investment

Our Process

1) Inspect vegetation health, sediment, and flow paths; 2) Remove invasives, debris, and excess sediment; 3) Replant or repair eroded areas as needed; 4) Record conditions and work performed for program files

What Affects the Cost

Swale length and vegetation density; invasive species pressure; sediment accumulation requiring removal; replacement plant materials; access and slope conditions

Best Time of Year

Major vegetation work is best done in late spring and summer, while inspections continue through the wet season to catch flow blockages.
