What we do


Recognizing and protecting historical sites

Parametrix guides our clients through identification, documentation, monitoring, and preservation of historical sites and properties in compliance with the National Historic Preservation Act. We determine the historic significance of bridges, buildings, landscapes, districts, and traditional cultural properties and develop documentation to protect those properties working with state and tribal historic preservation offices. Our experience includes directing archival research, historic building inventories, and historic bridge evaluations; documenting historic districts and acequias; and developing historic contexts.

Abo Canyon Second Track Project | Parametrix

Abo Canyon Second Track Project
Central New Mexico

Client: BNSF Railway
Partner: HDR Engineering

This 5-mile segment of new track eliminates a critical traffic bottleneck on BNSF’s transcontinental rail line and removes as many as 40,000 trucks a day from congested interstate highways. Cultural resources, including prehistoric rock art, were of significant concern during the environmental review process.

To address these concerns, we developed and engaged the public in a far-reaching public involvement effort. As a result, the project received broad-based support for the proposed cultural resources approach and memorandum of agreement. In addition, we developed a test blast protocol to ensure use of the appropriate thresholds during blasting in proximity to cultural resources.
