Maintaining Your Stormwater System - What is Required?
Property owners are responsible for cleaning and maintaining their private stormwater system and must submit a Stormwater Facility Maintenance Summary Form (Summary Form) and required documentation by July 31 of each year. Note: due to the Covid 19 pandemic, this date has been extended to September 15 this year.
What is a private stormwater system?
Stormwater systems are the infrastructure that capture and transport stormwater runoff before it flows into our streams, lakes and Puget Sound. Private stormwater systems often include features such as stormwater ponds, swales, ditches, pipes, catch basins and sometimes filters.
What are the benefits of maintaining your Stormwater system?
- Prevent damage to the stormwater system and costly repairs.
- Prevent flooding on the property.
- Reduce liability by preventing water-related damage to downstream properties.
- Reduce pollution in local aquifers, streams, lakes, wetlands and Puget Sound.
- Reduce erosion of stream banks and channels, which harm aquatic life and property.
To keep your stormwater system functioning properly and stay in good standing with your City agreement, follow these steps:
1. Inspect your stormwater system
Select the appropriate sections from the Stormwater Facility Checklist that apply to your system.
