Mitigation is an important product of the regulatory consultation process. When it is not possible to avoid or minimize adverse effects, mitigation is required. Outlined within a Memorandum of Agreement (MOA), mitigation measures can vary widely depending on the resource and complexity of the project. All mitigation should provide a direct public benefit and must be agreed to by all of the consulting parties. Note that per the Moss-Bennett Act, most projects over $50,000 typically allocate mitigation costs for cultural resources of around 1% of the total amount of the project costs.
Things to consider when developing mitigation options:
- What is the value of the resource/site to others?
- Are the mitigation costs commensurate with the value of the resource?
- Are the mitigation efforts commensurate with the scale of the project?
- Are there other options that don't include archaeological site excavation or histioric building documentation?
- What, if any, partnerships are available?
Mitigation measures may include public participation activities, support for an alternate cultural resource, or general non site-specific mitigation. There is no such thing as a standard mitigation package. Please feel free to think outside the box and outside of the project area. Past mitigation efforts have included, but are not limited to:
- Museum Exhibits
- Thematic or Multiple Property studies
- Additional inventory work
- History Essays - Historylink : Free, on-line encylopedia of Washington State's history (Contracting Info)
- Lecture series'
- Documentaries or Public Service Announcements
- Coffee table book
- National Register nominations
- Additional consultation to ensure compatible replacement buildings/structures
- Support for preservation non-profit organizations
- Moving and/or salvage - Building Removal Assessment Tool
- Climate Impact Assessment - CARE Tool
- Facade improvement grant
- School Curiculum
- Resource/typology Guidebooks
- Historic Structure Report
- Heritage Tourism projects
- Building component salvage and reuse
- Website development
- Internship Program
- Historic Context Development
- Interpretive Signage
- In situ preservation of cultural resources
- ARC GIS Story Map
- Preservation covenants
- Formal Documentation - DAHP mitigation standards
- HABS | HAER Standards - NPS
- Ethnographic studies
- Support for WISAARD development and enhancement - ACHP /NCSHPO letter on providing support
Note that DAHP, the lead agency, tribes, and all other consulting or concurring parties should come to an agreement on the type of mitigation. Please note that typically the mitigation must be executed before any work/demolition of the resource begins. In most cases, mitigation and/or documentation products provided to DAHP, will be retained by DAHP and/or others as specified in the MOA.
