City of Bainbridge Island
Private Stormwater Management
The City is responsible for the Island’s public stormwater system and more information is available on the Public Work’s Operations and Maintenance page. Private property owners are responsible for their own private stormwater systems.
Private stormwater systems provide for collection, conveyance, flow control and sometimes water quality treatment; and they might include a combination of the following components:
- Roof gutters and downspouts
- Catch basins
- Pipes (underground and/or aboveground)
- Culverts
- Swales
- Ditches
- Ponds, tanks, vaults, etc.
- Flow Control Structures
- Treatment Filters
- Permeable pavement
- Rain Gardens
General Stormwater System Maintenance Requirements:
- No pollution – “Only Rain Down the Drain” Prevent anything but rainwater from entering any stormwater drainage facility or system and immediately remove any pollution that is found in your stormwater system.
- Safe access – the ability to safely inspect, operate and maintain
- Functional and structural integrity – ensure the system is working as designed and constructed, and is maintained to standards (e.g. no broken parts, no cracks or holes, no erosion, etc.)
- Reducing debris and sediment load – prevent and remove sediment and debris that may block pipes or the facility from functioning as intended
- Vegetation management – plant, cut, remove vegetation as needed
- Good housekeeping – use, store, and dispose of household waste, yard waste, and hazardous waste appropriately
