Cucamonga Creek Watershed Regional Water Quality Project

The 52-acre Cucamonga Creek Watershed serves as a regional natural treatment system designed to improve water quality by diverting flows into a series of natural water quality ponds. Because of its potential for historical significance, the City of Ontario wanted to determine whether the area was eligible for listing in the National Register of Historic Places. 
 
To comply with Section 106 of the National Historic Preservation Act and National Environmental Policy Act (NEPA) regulations, ESA completed a Phase II Archaeological Testing and Evaluation in coordination with the City and the U.S. Army Corps of Engineers (USACE). This assessment needed to be completed under a tight deadline to ensure the larger environmental document would be finalized in time for public review. With an increase of field personnel and a well-coordinated effort, we ultimately completed the project one week ahead of schedule.
 
Ultimately, USACE and the State Historic Preservation Office agreed with our findings that the poor integrity of the archaeological site made the site ineligible for listing.
