Low Impact Development Handbook for the Tualatin Basin
Clean Water Services and its partners completed the Low Impact Development Approaches Handbook to promote sustainable development practices for Tualatin River Watershed in 2009. Low Impact Development Approaches (LIDAs) can maximize a site's potential by reducing or incorporating the area needed for stormwater management and water quality treatment while protecting natural resources and habitat.
Updated Sanitary Sewer Master Plan Adopted
Clean Water Services recently completed a two-year analysis of sanitary sewer capacity needs to serve the growing Washington County population, and on May 26, 2009 the Board of Directors adopted the Updated Sanitary Sewer Master Plan. The Plan is based on modeling of sanitary sewer flows anticipated from development of areas recently incorporated into the Urban Growth Boundary, infill development, and potential Urban Reserve areas.
The plan recommends the upsizing of numerous lateral, trunk and interceptor sewers, pump stations and force mains, and sizing of trunk lines to be extended to serve those areas anticipated for development. These recommendations will be incorporated into the 5-Year Sewer Capital Improvement Plans of the District and its member cities.
The capacity enhancement projects identified in the plan and accompanying cost estimates are used to help forecast financial needs and System Development Charges. The plan will serve as a guiding document for prioritizing Sanitary Sewer Projects for the next 7 to 10 years. If you have questions regarding the plan, contact the Conveyance Engineering Division at (503) 681-3615.
