Best Available Science Rule

The Washington State Office of Community Development (OCD) has developed its Best Available Science Rule (BAS). The Washington State Legislature amended the Growth Management Act (GMA) in 1995 to include a provision on best available science. It requires cities and counties to "include the best available science in developing policies and development regulations to protect the functions and values of critical areas" when they designate and protect critical areas. They also are to "give special consideration to conservation or protection measures necessary to preserve and protect anadromous fisheries." Click above on "Proposed Best Available Science Rule" for more information on the rule. Click here for growth management home page.

Preliminary Data Summary of Urban Stormwater Best Management Practices

The Environmental Protection Agency conducted a study of urban storm water discharges in 1997-98. The study is based largely on existing literature and data on best management practices (BMPs) that are used to control urban storm water runoff. Topics covered include: BMP performance measures and measurable goals, availability of measurement methods, design criteria, monitoring issues, costs and cost minimization opportunities, and the benefits and economic impacts of constructing and operating BMPs. The report and additional information are available by clicking above.
