Storm Water Master Plan 2008

The City of Warrenton, Oregon contracted with HLB-Otak, Inc. in 2007 for Phase 2 of their
Stormwater Master Plan to study their stormwater management system and develop a
stormwater management plan with Capital Improvement projects for the City to implement
in anticipation of continued growth.

The City of Warrenton is not currently obligated to manage stormwater per any specific
regulatory requirements. The City simply has a growing concern that increased development
activity would overload the existing system of ditches that have not been routinely dredged,
the tide gates that are leaky or missing, and the pump station that is nearing the end of its
useful life. The City recognizes that a comprehensive look is necessary to determine how
they should manage the system before investing stormwater revenue in any particular
project.
