King County Road Services - Stormwater research

Overview

The objective of this research effort is to compile information relevant to the treatment or flow control of stormwater in roadside ditches, determine effective ditch best management practices (BMP) options and promote their application by municipal stormwater permit holders.

Some of the tasks that have undertaken include: gathering available information by conducting on-line research of best management practices, contacting local stormwater professionals, posting the resulting information on this Web site and notifying potentially interested parties of the availability of this research.
