Subwatershed Master Plan
BBWARM is completing subwatershed master plans for developed subbasins within the BBWARM district. This planning effort began in 2011 with EPA grant funding for the first plan and includes:
- Inventory of existing stormwater systems and facilities (ditches, pipes, catch basins).
- Hydrologic analysis and modeling of stormwater flows.
- Identification and evaluation of stormwater problems and recommended solutions including maintenance, small works, and capital improvement projects.
- Public participation through stakeholder meetings.
- Completion of subwatershed master plans.
Each plan provides detailed information on stormwater facilities and stormwater flows within designated subbasins. The planning process includes a capital project scoring criteria used to prioritize projects for BBWARM's six-year capital plan and Whatcom County's Water Resources Improvement Program. Once complete, each subwatershed master plan will be considered by Whatcom County Council as an amendment to the 2006 Birch Bay Comprehensive Stormwater Plan.
Whatcom County Public Works employee Andrew Tischleder inspects a catch basin for the stormwater facility inspection and inventory.
Subwatershed Master Plan Map
The map below shows subwatershed master plan areas. Subwatershed master plans are complete for the Central North and Central South Subwatersheds. Work is currently underway on the Birch Point, Terrell Creek Urban Area, and Point Whitehorn Subwatersheds. Subwatershed master plans will not be completed for rural subbasins in the Terrell Creek watershed.
