FROM: Daryl Grigsby, Public Works Director
Prepared By: Brian Nelson, Supervising Civil Engineer
SUBJECT: APPROPRIATE GRANT FUNDS FOR MARSH STREET BRIDGE
REPLACEMENT PROJECT
RECOMMENDATION
Appropriate an additional $1,406,160 in grant funding for the Marsh Street Bridge Project , for a
total grant funding to match the federal funded allocation of $6,946,943.
DISCUSSION
Background
The Marsh Street Bridge, located near the intersection of Marsh and Santa Rosa Streets, was
approved by the City Council in January 2013 for removal and replacement. This followed a
determination by the California Department of Transportation (Caltrans) that the bridge, built in
1909, is structurally deficient. Upon this determination, the City contracted with Dokken
Engineering to conduct a bridge assessment. This assessment concluded that a complete
replacement of the existing bridge was the most prudent and cost -effective alternative given the
age of the structure.
On January 22, 2013, the City Council conceptually appr oved the removal and replacement of
the Marsh Street Bridge and proceeded with design of a new fully-replaced bridge. Dokken
Engineering began the design process, including development of the plans, specifications and
construction cost estimate for the bridge. That work is nearly complete. Dokken is close to
finalizing the environmental permitting process, and the City Council adopt ed the Final
Environmental Impact Report (FEIR) for the Marsh Street Bridge Replacement project on May
2, 2017.
On August 21, 2018, the Council authorized agreements for temporary and permanent
construction easements from adjacent property owners. The temporary easements are necessary
for equipment accessibility to San Luis Obispo Creek to conduct construction activities within
the creek, provide a staging and equipment area for the bridge contractor, and provide vehicular
and emergency access for a medical services business adjacent to the bridge. There will also be
permanent easements acquired from two of the owners for construction and maintenance of a
wing wall for the bridge.

Item 12
The temporary and permanent easements are also necessary for obtaining clearance from
Caltrans to enter the construction phase. This phase releases the Highway Bridge Program (HBP)
grant funds fo r construction, allows advertising the project for construction bidding, enables
award of the project to a responsive and responsible bridge contractor, and provides for
construction of the bridge. The construction of the Marsh Street Bridge is anticipate d to start in
Spring 2019.
Agreements have been reached for the easements and transfer of funds is expected to take place
in early October.
Project Remaining Tasks
The purpose of Caltrans HBP Grant Funding Program is to replace or rehabilitate public
highway bridges over waterways, other topographical barriers, other highways, or railroads when
the State and the Federal Highway Administration determine that a bridge is significantly
important and qualifies under the HBP program Guidelines, as is the case with the Marsh Street
Bridge.
Caltrans provided grant funding to support the preliminary engineer ing and right-of-way
acquisition, both of which are nearly complete. The below table outlines completed and ongoing
tasks that are critical for the construction phase to begin in 2019. Ensuring that funding is
appropriated will allow the work to proceed on schedule.
Project Delivery Tasks Anticipated Completion Date
Environmental Impact Report Certification February 2018
Regulatory Permitting Prior to Construction
Design October 2018
Right of Way Certification October 2018
Construction Spring 2019
ENVIRONMENTAL REVIEW
The City Council approved adoption of the Final Environmental Impact Report (FEIR) on May
2, 2017. In addition to National Environmenta l Policy Act (NEPA) approval with the FEIR,
environmental permitting should be nearly complete with the Department of Fish & Wildlife, the
Regional Water Quality Control Board, the Army Corps of Engineers and the State Historic
Preservation Office.

FISCAL IMPACT
The project was approved as part of the 2015-17 Financial Plan, page 3-156. This project is
88.53% funded by the HBP grant funding with a 11.47% City Local Revenue Measure match.
The table below shows the funding allocation for work complete d, as well as upcoming funding
requirements.

Marsh Street Bridge Replacement Project (Specification No. 90480)
(2) Design contract amendment from Dokken Engineering due to additional design &
property acquisition service costs
(1) Contract with Dokken Engineering, which includes design, environmental permitting,
and property acquisition
Staff recommends the appropriat ion of $1,406,160 in HPB grant funding that Caltrans’ has
provided to the City to the construction phase of the Marsh Street Bridge Replacement project.
ALTERNATIVES
Deny allocation of grant funding. The City Council could choose to not allocate grant funding
for the project. Staff does not recommend this alternative. Recognizing the availability of grant
funding is necessary to fully fund ongoing des ign and right of way costs, as well as budgeting for
construction in 2019.
