DATE; May 13, 1997
SUBJECT: EI Toyonal Bridge Replacement Project Project No: 0662-6U4016
Specific Request(s) or Recommendation(s) & Background & Justification
I. Recommendations:
Refer the request from the Public Works Director to increase the appropriation for the EI Toyonal
Bridge replacement project from $75,000 to $150,000 to the Finance Committee.
II. Financial Impact:
None to General Funds.
III. Reasons for the Recommendation and Background:
On September 17, 1996, the Board of Supervisors approved the Joint Exercise of Powers
Agreement with the City of Orinda and the East Bay Municipal Utilities District (EBMUD) to repair
two landslides and to replace the timber bridge on El Toyonal. The bridge was to be replaced by
this summer. At that time, the Board appropriated $75,000 for the replacement of the bridge. The
estimate was based on purchasing a modified railroad car to replace the one lane timber bridge.
Subsequent to the repair of the landslide, it was determined that it would not be feasible to transport
a 70-feet long railroad flat car to the site through Wildcat Canyon Road and the repaired EI Toyonal.
As an alternative, the Public Works Department explaored the feasibility of erecting a panel bridge
at this site. A panel bridge is made up of individual components no longer than 12-feet and is very
mobile. The cost of the panel bridge is estimated to be $150,000. Access problem makes other
bridge structures more expensive to construct than the panel bridge.

Increasing the appropriation to $150,000 will allow the project to proceed this summer and will
complete the emergency evacuation route by this fall.
As an alternative, the County has received a Federal grant to replace the one lane panel bridge
on Delta Road over the Rock Slough in East County. This project is scheduled to be under
construction in April 1998. When the replacement project is complete, the 150-feet long panel
bridge will become available and can be moved to and erected on EI Toyonal within the
appropriation set by the Board. The Deparmtent will continue to maintain the existing timber
bridge for pedestrian traffic until the panel bridge is installed.
The third alternative is to request the City of Orinda to share a part of the cost increases to
keep this project on schedule.
IV. Consequense of negative action:
The bridge replacement project will not proceed and the County would not be able to fulfill its
commitment to the City of Orinda and EBMUD.
