Lake Whatcom Capital Project Plan Update

All capital projects included in the original Lake Whatcom Comprehensive Stormwater Plan have either been built or are on the County’s current six-year capital project plan, the Water Resources Improvement Program. In 2017, Whatcom County Public Works completed a plan update to identify and prioritize new water quality treatment capital projects within the county portion of the Lake Whatcom watershed (outside of city limits).

The update process included:

  • Collecting information on known surface water problems and possible water quality treatment capital projects from the public and Lake Whatcom Management Program partners.
  • Engineering analysis to identify and scope new capital projects.
  • Evaluation and prioritization of proposed projects based on preliminary cost estimates and estimated phosphorus load reduction.
  • Developing conceptual designs for priority capital projects.
  • Developing a draft and final addendum to the Lake Whatcom Comprehensive Stormwater Plan. 

The Final Lake Whatcom Capital Project Plan was approved by the Whatcom County Council on November 21, 2017 (Resolution 2017-063).
