OLYMPIA – Proposed new rules for managing stormwater runoff from development projects will be the topic of a series of open houses scheduled by Thurston County . The new rules are spelled out in a proposed update to the county's 1994 Drainage Design and Erosion Control Manual. The update is required to meet statewide standards set by the Department of Ecology.
Three general public open houses will be held from 6:30 p.m. to 8:30 p.m. on the following days:
- May 28 at the Thurston County Courthouse, 2000 Lakeridge Drive S.W. , Building 1, Room 280 in Olympia ;
- June 2 at the Thurston County Fairgrounds Heritage Hall, 3054 Carpenter Road S.W. near Lacey; and
- June 4 at Parkside Elementary School , 301 Central Avenue E. in Tenino.
Two additional technical workshops geared specifically toward the engineering and development communities will be held June 8 from 1 p.m. to 3 p.m., and June 10 from 6:30 p.m. to 8:30 p.m. Both workshops will be held at the Thurston County Courthouse, 2000 Lakeridge Drive S.W. , Building 1, Room 152 in Olympia.
A draft of the updated drainage manual is available online at www.co.thurston.wa.us/stormwater. Copies for viewing are also available at the Timberland Regional Library branches in Tumwater, Olympia , Lacey, Tenino and Yelm. A free CD of the manual is available at the Thurston County Water Resources office, 929 Lakeridge Drive S.W. , Building 4, Room 100 in Olympia .
The purpose of the Drainage Design and Erosion Control Manual is to help reduce the amount of pollution and erosion caused by stormwater runoff entering rivers, streams, Puget Sound and the groundwater. The manual applies to all development and redevelopment projects in unincorporated Thurston County .
