Stormwater Action Monitoring
The Stormwater Action Monitoring (SAM) brings together municipal stormwater permitees to collaborate on monitoring needs. SAM provides structure, transparency, and accountability for permittees and stakeholders alike.
The group aims to improve stormwater management, reduce pollution, improve water quality, and reduce flooding. They do this by working together to measure stormwater impacts on the environment and evaluate the effectiveness of efforts to manage stormwater.
SAM is a collaborative, Western Washington regional stormwater monitoring program that is funded by more than 90 cities and counties, the ports of Seattle and Tacoma, and the Washington State Department of Transportation. Additional funds and in-kind are contributed by other Washington state agencies, federal agencies, local businesses, and community volunteers.
All of these municipalities are covered by state municipal stormwater permits. This approach is unique since no other permit-driven monitoring in the state is defined and funded by permittees.
Collectively, municipal stormwater permittees in Western Washington spend an estimated $250 million per year to manage stormwater. About one percent of this expenditure is invested in a pooled fund dedicated to conducting this regional monitoring program. All jurisdictions — large and small — can benefit from SAM projects that are designed to produce regionally transferable findings. All permittees implement SAM findings to protect downstream waters such as lakes, streams, and bays.
The Stormwater Work Group (SWG), a formal stakeholder group, provides leadership and oversight on SAM projects. The Pooled Resources Oversight Committee (PRO-C), a subgroup of the SWG, oversees Ecology's administration of SAM's pooled resources. Ecology acts as the administrative entity that manages SAM funds and executes SAM contracts. SAM is the new name for the Regional Stormwater Monitoring Program (RSMP).
What is SAM's goal?
SAM's goal is to improve stormwater management to reduce pollution, improve water quality, and reduce flooding. To achieve this goal, SAM monitoring targets three broad strategic categories:
- Effectiveness studies — How well are required or innovative stormwater management practices working? What are the most common types of pollution in stormwater?
- Source identification — What are the common sources of illicit discharges? What are some regional solutions and elimination methods? (webpage coming soon - see below for first completed SAM source identification study)
What to expect from SAM
SAM launched in 2014 (under the name Regional Stormwater Monitoring Program). In the first three years the team began four status studies, 10 effectiveness studies, one source identification project, and a community education effort.
Most projects are in a data analysis stage, a couple projects were recently completed. We — as the administrator of SAM — provide quarterly and annual reports. Findings from SAM will help stormwater managers at all levels of government, field practitioners, and policy makers improve management practices and set funding priorities.
We want to communicate SAM results broadly and effectively with stormwater managers and municipal stormwater decision makers for adaptive management of stormwater programs and activities.
Symposium and workshops
The first SAM Symposium was held June 1, 2017 to showcase all active SAM studies to date. Status updates or interim findings were given on each of the active projects. This allowed permittees to learn about the wide range of monitoring studies underway.
