Maintaining Your Neighborhood Stormwater Facilities

Wet pond at Courtney PlaceNeighborhood stormwater facilities play a key role in preventing flooding, pollution and erosion. The phrase "stormwater facility" refers to any landscaped or structural feature that slows, filters, or infiltrates runoff from your property after a rainfall. Stormwater facilities come in many shapes and forms -- from simple swales to more complicated stormwater ponds.

 

The ponds, ditches and depressions that you see every day may actually be neighborhood stormwater facilities. Without them, polluted stormwater runoff can rush into rivers and streams, or enter drinking water aquifers. Stormwater facilities also help prevent neighborhood flooding -- a huge benefit in the stormy Pacific Northwest.

 

Annual Stormwater Facility Maintenance Inspections

Yard debris should be cleared from this stormwater pondThurston County requires property owners to inspect and maintain stormwater facilities on their private property, including facilities located on commonly owned land within a housing development. The term "stormwater facility" refers to any structure that conveys or stores stormwater runoff. Examples include catch basins, swales and stormwater ponds.

 

Annual Maintenance Inspections

Each year, Thurston County inspects private and commercial stormwater facilities to make sure they are functioning properly, and provides property owners with a report on the findings. Within 30 days of receiving the report, property owners are required to return a "maintenance log" stating that they either corrected the deficiencies, or plan to correct them in the future.
