What we do

Research, analysis, and the plan that follows

Watershed councils, agencies, and community groups bring a question. We study it, rank the options, and write the plan.

01

Research

Habitat, sediment, and limiting-factor assessments for watershed councils and agencies. Fieldwork, sampling, and analysis follow the agreed scope when needed.

  • Habitat assessments
  • Sediment and shade
  • Limiting factors
02

Analysis

Ranks restoration reaches using habitat data, surveys, GIS, and existing reports, so the work starts where it matters most.

  • Restoration priority
  • Fish passage
  • Rearing habitat

Supporting method: GIS and mapping. Drinking-water and housing overlays, passage, and habitat maps that explain the resource visually.

03

Planning

The action plan is the written packet after the research: the plan a council can fund, with restoration priorities for the work plan.

  • Action plans
  • Restoration work plans
  • Scope and timeline

Completed projects

Tillamook County Natural Hazard Mitigation Plan

The 2015 Tillamook plan ranks hazards and lists mitigation actions. It names flooding, sea level rise, and earthquake.

Full plan
