Project Summary:

Mendocino County Department of Transportation (MCDOT) is seeking the services of a Professional Engineering Design firm to provide civil engineering for a state and locally funded Sustainable Transportation Planning Grant (STPG) project.

This project will conduct a vulnerability analysis of the storm drainage system of county-owned and maintained rural roadways in 5 areas. These areas are the northern part of the Ukiah, Talmage, Old Hopland, Irish Beach, and west road in Redwood Valley. The analysis will inventory the storm drainage system in these areas, including rural culverts, with data such as location, diameter, pipe material, length, condition, and inlet/outlet elevations (all of which can affect a culvert's conveyance capacity). The analysis will then evaluate the existing system’s ability to convey the anticipated flows predicted using the State's latest climate prediction models. The County will utilize the findings of this analysis to prioritize replacement of culverts that cannot accommodate the impacts of climate change.

Submission Information:

Vendors must submit four (4) copies of their proposal: three (3) complete paper copies with original Vendor signature, and one (1) complete copy on USB Flash Drive.
