WILLIAM RICH AND ASSOCIATES has successfully completed small and large-scale cultural resources projects that include land development, ecological restoration, timber harvest plans, transportation, and cannabis permitting projects. Our services include all aspects of conventional cultural resources management: feasibility studies, management plans, research designs, archaeological investigations, resource evaluation, cultural resources mapping, mitigation prescriptions, construction monitoring, and background research.  We have a reputation for respectful collaboration with Native American tribes.

We have extensive experience with CEQA, NEPA, Section 106 NHPA,  and other environmental regulations as they pertain to cultural resources.  WRA brings together a team of associates best suited for your needs : archaeologists, architectural historians, historians, ethnographers, geoarchaeologists, researchers and as needed, botanists and paleontologists.

We enjoy working in Humboldt, Mendocino, Del Norte, Trinity and Siskiyou Counties.

WILLLIAM RICH AND ASSOCIATES recognizes and affirms that cultural resources work is typically undertaken to satisfy local, state, or federal regulation of a project proponent.   In this environment WRA’s services may be undertaken by clients with certain apprehension about what to expect.  WRA strives to seek opportunities in the conduct of its work that foster positive outcomes for all of a project’s stakeholders.  Open information sharing  and communication among affected parties is a goal and expected outcome of any cultural resources project undertaking by WRA.   WRA seeks to educate its clients about the value of the resource and to facilitate a smooth navigation of any given regulatory process.
