Following several important rock fall mitigation projects, drainage improvements, and paving the road from the dam to the man camp for SRP at Horse Mesa Dam, DBA recently completed the 4.2 miles of roadway from SRP’s main gate down to the dam through the canyon. Through several discussions with Salt River Project engineering personnel and multiple cost models for the roadway construction, DBA suggested a soil cement solution to stabilize the roadway down to the dam. The project will be completed this week. Brush fires along SR-77 near Tortilla Flat curtailed construction for a short period of time earlier this month, but once cleared by the Forest Service, DBA crews returned to the job site and completed the job. Total constructed value of this project was $1,362,230.00 which included grading, compacting and placement of the soil cement.
This portion of the work completed for SRP at Horse Mesa Dam is a small part of the project overall which included the building of a 60′ tall gabion wall with a 500 KJ fence at the top to stabilize a talus 1:1 slope; adding a 100 KJ fence to another area above the upper dam road; rock excavation for an addition to the Maintenance Building on site; drainage improvements, and AC paving the road to the man camp.
