This project consisted of a complete evaluation, design and replacement for the original 1923 sewer line and electrical services for the historic structures at the Ansel Adams Gallery and dark room, and residences located near the Visitor Center in Yosemite National Park.

Provost & Pritchard also evaluated the existing line, provided design surveys, conducted a geotechnical investigation, created a conceptual civil design, as well as prepared construction cost estimates for utility improvements that included water, sewer, drainage, grading.
