Oregon’s Habitat Mitigation Policy (HMP)
Oregon’s Habitat Mitigation Policy (HMP), administered by the Oregon Department of Fish and Wildlife (ODFW), establishes a framework for evaluating and offsetting impacts to important fish and wildlife habitats. Under the policy, habitat is categorized from 1 through 6 based on ecological function and conservation priority. Categories 2–5 generally require compensatory mitigation when impacts cannot be avoided or minimized.
How HMP Mitigation Is Calculated
When a project affects mapped habitat, ODFW determines the category, impact acreage, and applicable mitigation ratio. Required mitigation is then quantified based on habitat category, type, and level of impact. These requirements are incorporated into permit conditions or EFSEC site certificates and must be satisfied before project impacts occur.
Using Bank Credits to Satisfy HMP Requirements
Mitigation credits from NGBCB may be used to offset qualifying Category 2–5 impacts within the same Geographic Service Area. Because credits are generated under an approved conservation bank instrument, they represent pre-established ecological uplift that aligns with ODFW’s mitigation framework. This allows project proponents to satisfy HMP obligations through a documented credit transaction rather than developing, constructing, and monitoring project-specific mitigation sites.
Advantages Over Project-Specific Mitigation
Under permittee-responsible mitigation, developers assume responsibility for habitat design, implementation, monitoring, performance standards, and long-term management. Bank-based mitigation transfers those obligations to the approved bank sponsor, reducing implementation risk and long-term compliance exposure. Credits provide a structured and agency-recognized mitigation pathway that supports predictable permitting outcomes.
Early Coordination and Planning
Because HMP mitigation requirements are tied directly to mapped habitat and impact categories, early coordination is strongly recommended. Engaging during project siting or preliminary design allows mitigation strategy to be incorporated into schedule, budgeting, and regulatory planning. Confirming service area eligibility and anticipated credit needs early can reduce delays during formal agency review.
For EFSEC and Energy Developers
Projects reviewed through EFSEC or other state permitting pathways frequently trigger HMP mitigation requirements. Fully approved bank credits provide a clear and defensible mechanism to satisfy these obligations within established regulatory timelines.
