FISCAL IMPACT:
There is no impact to the County General Fund. This project is funded by 60.5% Prop. 1B Funds, 34% Federal HR3
Funds, 5.5% Gas Tax.
BACKGROUND:
Marsh Creek Road is a rural road in Eastern Contra Costa County. Marsh Creek Road was built during the 1920’s
and 1930’s, and needs to be upgraded to current design standards. Fatalities at this location of Marsh Creek Road
have made the need to bring the roadway up to current design standards even more critical. The purpose of this
project is to improve a 2,900 ft. section of Marsh Creek Road west of Round Valley Regional Park to Lydia Lane.
The improvements are intended to develop a recovery area which will assist drivers when their vehicles veer out of
the travel lane and to increase overall road safety by widening the travel lanes and improving driver sight distance by
altering the road’s vertical and horizontal curves to meet current design standards.
The project involves several improvements: Widening the existing 10 ft travel lanes to 12 ft. and adding 8 ft.
shoulders (6 ft. paved and 2 ft. of shoulder backing). Utility poles and fences will be relocated further from the travel
lanes and two existing culverts will be extended (approx. 60 ft. in combined total length) to provide additional clear
areas for evasive maneuvers. Roadside swales and ditches will be graded to accommodate roadway drainage for the
wider cross-section. One tree will be removed and tree trimming may be necessary. A hill along the north central
side of the project may need to be slightly regraded to improve driver sight distance. In addition, improved signing
and striping will better inform motorists of upcoming curves, lane location, and safe speed limits. The project will
also improve general visibility along horizontal and vertical curves. Additionally, the improvements will include a
Class III Bike Route.
The project will temporarily impact traffic flow during construction, however, with traffic management measures in
place, these impacts will be less than significant. The County will ensure that at least one lane will remain accessible
to the public at all times during project construction and notices of the project’s start date and times of construction
will be posted in area publications. No activities requiring lane closure will be allowed during the morning commute
hours (5:30am to 8:30am Mon-Fri.). The morning commute hours will be strictly adhered to unless modified upon
written approval by the resident engineer. Traffic flow will be controlled by flaggers based on the level of flow from
each direction (east or west bound), with increased traffic flow from either direction given priority. It may be
necessary during construction to partially close the park entrance for an estimated half day to pave the entrance lane.
In order to minimize damage to any nearby trees, any roots exposed during excavation will be cut cleanly and tree
branches will be trimmed. Real property transactions and utility relocation may be necessary in support of this
project.
Construction is scheduled to begin 2011 or 2012 with an estimated 50 working days to completion.
CONSEQUENCE OF NEGATIVE ACTION:
Delay in approving the project will result in a delay of design and construction and may jeopardize funding.
