TO: CITY COUNCIL
FROM: TERESA MCCLISH, DIRECTOR OF COMMUNITY DEVELOPMENT
BY: ROBIN DICKERSON, CITY ENGINEER
SUBJECT: CONSIDERATION OF AN AMENDMENT TO THE AGREEMENT FOR
CONSULTANT SERVICES WITH QUINCY ENGINEERING FOR THE
SWINGING BRIDGE PROJECT
DATE: MAY 14, 2019
SUMMARY OF ACTION:
Approval of Amendment 3 to the Consultant Services Agreement for Quincy Engineering
to complete the Swinging Bridge Project.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
The cost for Amendment 3 is $26,000.
Original Amount $ 33,000.00
Amendment 1 $ 54,724.00
Amendment 2 $ 0.00
Amendment 3 $ 26,000.00
Total $113,724.00
Currently the Swinging Bridge Account has a balance of $499,682.12 for design and
construction. Construction costs for the Swinging Bridge continue to escalate.
Amendment 3 will allow the consultant to better define these costs, and finalize an option
for rehabilitation of the Swinging Bridge.
RECOMMENDATION:
It is recommended the City Council approve and authorize the Mayor to execute
Amendment No.3 to the Consultant Services Agreement with Quincy Engineering to
complete the Design and Environmental Phase, in an amount not to exceed $26,000.
BACKGROUND:
The Swinging Bridge was originally constructed in early 1875 by the Short family, whose
land was divided by the Arroyo Grande Creek. The bridge span length from cable tower
to cable tower is approximately 133 feet and is suspended 40 feet above Arroyo Grande
Creek. The Swinging Bridge is owned and maintained by the City of Arroyo Grande.

During the spring of 2016, the Swinging Bridge was closed for several weeks of
maintenance work and reopened on May 23, 2016. Based on available information,
maintenance and repair work has occurred at periodic intervals. The Swinging Bridge’s
major maintenance work occurred in 1913, 1918, 1947, 1953 and 1985. More
exhaustive repairs were completed in 1995 after a tree fell on the Swinging Bridge. The
bridge is currently open but has a 5-person weight limit.
ANALYSIS OF THE ISSUES:
On April 13, 2016, the City Council awarded an agreement to Quincy Engineering to
complete the Swinging Bridge Evaluation. Based on the unknowns of the necessary
repairs, the Swinging Bridge Evaluation was phased. Phase One work included an
evaluation of the critical components of the bridge which included survey of the bridge
and cables, inspection of the bridge members, joints and connections and bridge load
rating analysis. A report was prepared and a bridge capacity limit was set at 5 people.
On July 26, 2016, the City Council amended Quincy’s contract to include Phase Two,
which was to evaluate the cable anchorages and foundations. Retrofit measures were
also to be developed to ensure that the Swinging Bridge remains functional in the long
term. These measures will be developed into construction documents suitable for public
bidding and construction to support phase three which is construction.
In July 2017, Quincy submitted 65% plans, estimate and an executive summary of the
work completed to date for Phase Two of the Swinging Bridge Project. At that time, staff
identified the need for additional geotechnical services to evaluate the existing cast-in
drilled hole (CIDH) piles at the existing cable anchors and to provide design parameters
for the new CIDH piles at the abutment. The geotechnical investigation revealed that the
existing abutments consist of a vertical wall of limited width with no underlying footing.
The abutments exhibited signs of undermining. Quincy has proposed to retrofit the
abutments utilizing CIDH piles to ensure the safety of the tower support foundations.
Accordingly, Quincy is requesting additional fees for the design of the abutments and to
evaluate the existing CIDH piles at the existing cable anchors. Additional geotechnical
information and evaluation are required for design of these foundations and included in
the proposal. The geotech will also be evaluating the liquefaction potential and making
recommendations. There is also additional effort for finalizing the plans and

specifications as well as additional project management and coordination based on
these recommendations.
The additional scope of work includes fees for updating the construction cost estimates
and providing additional specifications for the CIDH piles.
The City also requested that Quincy include the anticipated environmental scope of
services.
The cost of these additional services is a not to exceed amount of $26,000. (Attachment
1). This amendment will also extend the agreement for an additional year, and will expire
April 13, 2020.
ALTERNATIVES:
The following alternatives are provided for the Council’s consideration:
1. Approve the Amendment with Quincy Engineering;
2. Do not approve the Amendment with Quincy Engineering; or
3. Provide direction to staff.
ADVANTAGES:
Amending the Agreement with Quincy Engineering will allow the construction documents
to be completed in a timely manner.
DISADVANTAGES:
Additional funding expenditures are required to complete the task.
ENVIRONMENTAL REVIEW:
In compliance with California Environmental Quality Act (CEQA) the project is
categorically exempt per section 15061(b)(3) of the CEQA Guidelines.
PUBLIC NOTIFICATION AND COMMENTS:
The Agenda was posted at City Hall and on the City’s website in accordance with
Government Code Section 54954.2. At the time of report publication, no comments have
been received.

Re: Cost Proposal for Swinging Bridge Additional Services, CIP Project Number 5620
Dear Ms. Dickerson:
It is our pleasure to submit Quincy Engineering, Inc.’s (Quincy) Cost Proposal for additional services for Phase 2 of
the Swinging Bridge Project.
In July 2017 Quincy submitted 65% plans, estimate and an executive summary of the work completed to date for
Phase 2 of the Swinging Bridge Project. At that time, we identified the need for additional geotechnical services
to evaluate the existing CIDH piles at the existing cable anchors and to provide design parameters for the new
CIDH piles at the abutment. The geotechnical investigation revealed that the existing abutments consist of a
vertical wall of limited width with no underlying footing. The abutments exhibited signs of undermining. Quincy
has proposed to retrofit the abutments utilizing CIDH piles to insure the safety of the tower support foundations.
Accordingly, Quincy is requesting additional fees for the design of the abutments and to evaluate the existing CIDH
piles at the existing cable anchors. Additional geotechnical information and evaluation are required for design of
these foundations and that is why additional services are required from Yeh and Associates whom will build off
the previous work done by Fugro. Yeh will also be evaluating the liquefaction potential and making
recommendations. There is also additional effort for finalizing the plans and specifications as well as additional
Project Management and coordination.
The additional scope of work includes fees for updating the construction cost estimates and providing additional
specifications for the CIDH piles.
The City also requested that Quincy include the anticipated environmental scope of services. Quincy contacted
SWCA who will perform these services and it will include the following Environmental Tasks:
Task 4.1 - Literature Review
SWCA will conduct a query of the California Natural Diversity Database (CNDDB), managed by the California
Department of Fish and Wildlife (CDFW), prior to conducting field surveys. The database query will provide SWCA
with a list of reported occurrences of special-status plant species, wildlife species, and sensitive habitats which
have been documented in the Arroyo Grande U.S. Geological Survey (USGS) 7.5-minute quadrangle and the
surrounding quadrangles. SWCA will also review in-house documents that we have prepared for projects within
the City.
Task 4.2 - Reconnaissance Field Survey
Following the literature review, SWCA will conduct a reconnaissance field survey of the project site. The purpose
of the survey will be to: (1) evaluate existing conditions to determine suitability for the presence or absence of
special-status plant and wildlife species; (2) document and record species observed; and (3) map all habitats and
sensitive resources present using a Trimble® GeoXT Global Positioning Systems (GPS) unit capable of sub-meter
accuracy. Existing site conditions and resources will be photo-documented.
For botanical resource issues, SWCA will analyze the existing conditions of the site and determine the potential
for special-status species to occur. SWCA proposes to conduct one survey upon approval of this contract.

Task 4.3 – Biological Memorandum Preparation
SWCA will prepare a detailed biological memorandum based on the literature review, field survey, and mapping
results. The final memorandum would include a discussion of existing conditions, identified regulatory concerns,
list of species observed on-site, and habitat map. The habitat map would be utilized to determine impact
calculations based on the project site plans and existing site conditions. Recommended mitigation measures
would be included to avoid or minimize impacts to sensitive resources, as applicable. Any limitations of surveys
and conclusions would also be addressed within the memorandum.
Task 4.4 – CDFW Lake and Streambed Alteration Agreement (Optional Task)
As an optional task, SWCA would prepare the Lake and Streambed Alternation Agreement for project activities
that may result in potential impacts to the jurisdiction of California Department of Fish and Wildlife. This area of
jurisdiction is traditionally known as the top of bank or furthest extent of riparian. It is SWCA’s understanding that
CIDH activities for the abutment may occur within the top of bank and thus require the submittal of a Lake and
Streambed Alteration Agreement application. Submittal of the application to CDFW provides the agency the
financial mechanism to review the project and determine if an agreement is necessary or not. The City would
provide the CEQA Document (assumed Categorical Exemption) and the necessary fees for the application based
on project cost. The labor cost for prepare and submit the application and coordination with the project team is
estimated to be no more than $1,000.
During a January 2019 teleconference we discussed the need to identify the location of utilities in conflict with
the new work. The City will provide the Centennial Park plans to locate these utilities. Quincy will also identify
possible environmental clearance as well as permitting issues related to the abutment construction.
Based on our updated Phase 2 - Scope of Work, our current agreement will require and amendment amount of a
Not to Exceed Cost $ 26,000.
In the event that the information contained herein is different than what you expected, please contact us and we
will adjust the scope and cost proposal accordingly. Please feel free to contact me at (916) 368-9181, via my
personal cell phone at (916) 799-3891, or via my email at markr@quincyeng.com
