Stormwater Drainage System
What is Stormwater?
Stormwater is rainfall, snowmelt, or any precipitation, that is not absorbed into the soil.  It runs off rooftops, over sidewalks, down street curbs and across parking lots, eventually entering our local streams, Woodin and Mill Creeks.

Stormwater Drainage Management
Battle Ground residents pay a monthly utility fee for Stormwater Drainage.  The public utility is the managed  infrastructure that collects the stormwater and the systems used to assure that it does not contain pollutants when it reaches our streams.

The monthly utility fee collected from city residents pays for the many components of the stormwater drainage system:

Stormdrainage Pond      


Biofiltration Swale
Publicly Owned Stormwater Facilities 
The city owns and is responsible for maintaining
over 80 stormwater facilities, like the pond
pictured above.  Maintenance includes litter
pick-up, mowing, weed eating and tree removal.
    Inspection of Privately Owned Facilities
 As required by the WA Department of Ecology,
the city inspects all private stormwater facilities
(like the swale pictured above) and works with
owners to ensure the facilities are in
compliance with DOE regulations. 
 Catch Basins and Curb Inlets    Stormwater Infrastructure
Catch Basins & Curb Inlets
There are over 1,800 catch basins and curb inlets within the city's stormwater drainage
system.  Per current DOE requirements, each is inspected every 5 years.  Beginning in 2017,
the requirement calls for inspections
every 2 years.

  Infrastructure Design & Construction
The city is responsible for the design and construction of the stormwater infrastructure.
Like sewer and water infrastructure, most components are located below the surface. 
 Erosion Control    Stormwater Facility Reconstruction
 Erosion Control
The city regularly conducts inspections to
ensure that erosion control practices
are appropriate and in compliance with
DOE regulations. 
   Stormwater Facility Maintenance
Aging stormwater facilities may
 require reconstruction (removing trees and silt
and replanting grasses) in order to provide the elements necessary to filter and treat water     before it is released into our waterways.
 Illicit Discharge    Stormwater Outfall
 Investigating Illicit Discharge
Illicit discharge is the release of contaminants
into the stormwater system.  The city
is required to investigate and report
incidents involving illicit discharge.
  Stormwater Outfalls 
There are over 150 outfalls into Mill and
Woodin Creeks that the city is required to
map and inspect.
