Whatcom County study finds 94 drainage problems in Point Roberts, proposes 13 capital projects
Summary
An 18‑month study for Point Roberts identified 94 drainage problems and prioritized 13 capital projects, 22 small‑works fixes and seven follow‑on studies. Consultants warned that high costs, cultural‑resource permitting and limited local funds mean full implementation could take decades without additional grants or a local stormwater utility.
Whatcom County and consultant Tetra Tech on Tuesday presented the final findings of an 18‑month drainage study for Point Roberts that cataloged 94 distinct drainage problems and proposed a package of responses including 13 capital projects, 22 small‑works projects and seven follow‑on technical studies.
"We identified 94 distinct drainage problems in Point Roberts," said Eric Navra, project manager for Whatcom County's study. He and consultant Alex Boscher said the problems range from undersized conveyance and failing infrastructure to site‑specific issues on private land that fall outside the county's authority.
The study combined watershed mapping, a 60‑year precipitation time series from nearby Blaine, hydrologic and hydraulic modeling and community complaints to generate a prioritized list of projects. The consultants said many of the large problems are systemic and that several relatively few capital projects could resolve multiple problem sites.
Navra and Boscher emphasized caveats: cost estimates are planning‑level with large contingencies; cultural resources are widespread on the peninsula and must be assessed by qualified archaeologists before many projects can proceed; and some issues proved to be private‑property disputes or otherwise infeasible for county action.
The report recommends next steps: adoption of a drainage management plan by county council to prioritize projects in the county capital improvement program, pursuit of state and federal grants, and targeted follow‑on studies in areas such as Maple Beach to evaluate cross‑border influences from nearby Delta developments.
The county will post the final report, the presentation and the recording online. Advisory committee members were asked to consider a motion at their next meeting to request that county council adopt the drainage management plan so the county can prioritize funding and pursue grants.
