Body
DISCUSSION / BACKGROUND
The Hazel Valley Road at EID Canal Bridge Replacement Project (Project) will replace the existing bridge built in 1940 that is functionally obsolete by today's standards due to its narrow 10 foot width, substandard geometric alignment and barriers, accelerated wood rot issues, seismic analysis, and service life and structure age.
The Project consists of construction of a new, simple-span, precast, pre-stressed deck slab bridge over the El Dorado Irrigation District's EID canal; El Dorado Canal including construction of concrete bridge abutments on cast-in-drilled hole piles, concrete wing walls, Midwest guardrail system, concrete retaining walls, drainage systems, grading and paving for new bridge approaches and re-aligned roadway and removing existing bridge.
Construction of the Project will require significant work immediately adjacent and over the EID canal. The water in the EID canal is used for drinking water and for hydroelectric power generation. Since any damage to the canal that interrupts the flow of water through the canal might cause EID to suffer damages, EID requested an Encroachment Agreement to detail the rights and obligations of each party.
Due to federal funding, both California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) compliance are required. A CEQA Mitigated Negative Declaration was approved by the Board on June 2, 2015 (Item 23). A Caltrans NEPA Categorical Exclusion Determination was issued on August 4, 2015 and NEPA Re-Validation was issued on March 19, 2018.
All required environmental permits and right of way have been acquired for the Project.
Department of Transportation (Transportation) received federal funding authorization (E-76) for construction phase activities on April 10, 2018.
As a federally funded Project, the Contract Documents have been federalized and incorporate the current Caltrans Disadvantaged Business Enterprise (DBE) requirements. The DBE goal is 16%.
