DESIGN ENGINEERING SERVICES FOR
ESCALON-BELLOTA ROAD BRIDGE (29C-051) OVER MORMON SLOUGH REPLACEMENT
PROJECT – PHASE II
REQUEST FOR PROPOSALS
The San Joaquin County Department of Public Works (SJCDPW) requests technical proposals from
qualified consulting firms to undertake, perform, and complete the tasks set forth in Request for
Proposals – SJCDPW-RFP-21-05. The selected Consultant (CONSULTANT) will perform professional
and technical engineering services for the proposed Escalon-Bellota Road Bridge (No. 29C-051) over
Mormon Slough Replacement Project (PROJECT). The CONSULTANT will be requested to enter into a
Consultant Services Agreement with San Joaquin County (County) as set forth in this Request for
The County will complete the project in three phases. Phase I of the project concluded with the
completion of the Type Selection Memo evaluating alignment and structure replacement options. The
Type Selection Memo recommended Alternative 3A, replacement of the entire existing structure with a
new cast-in-place, prestressed box girder bridge on a new alignment to the west of the existing bridge. A
geomorphology study was completed to predict the stream migration behavior and place the bridge in
the appropriate location. The report determined that without a permanent mitigation at the south bank,
the lateral migration could move from 80’ to 100’ in the design life of the new bridge. In December 2020,
the County submitted the memo to Caltrans for review and concurrence. Caltrans responded with a list of
additional items that need to be addressed in the final Type Selection Report before it is approved.
Caltrans comments include a evaluating a hardscaping option on the south bank, possibly designing a
two-span structure with a hinged abutment on the south end to allow for future lengthening of the
structure, and including an evaluation of replacing the structure in the current alignment.
Phase II tasks will include the hire of a design consultant, provide project management/oversight,
evaluate hardscaping and/or hinged abutment options to reduce proposed bridge length, produce an
approved formal Type Selection Report, obtain NEPA and CEQA environmental clearance, conduct
public outreach, utility coordination and prepare both 35 percent and 65 percent Plans, Specifications
and Estimate (PS&E).
Phase III scope will be finalized on the completion of phase II. It will consist of permitting, required
environmental mitigations, right-of-way certification, final design, 100 percent PS&E, bidding and
construction support, and advertise/award of the Project.
The work effort of Phase III will be performed by the CONSULTANTS at the discretion of the County at a
later date under a separate contract. Each phase will be approved by the San Joaquin County Board of
Supervisors and will be initiated by a separate written Notice to Proceed.
The CONSULTANT shall be required to provide all labor, equipment, tools, and facilities necessary for
the completion of the PROJECT’s design and environmental clearance. All work shall comply with San
Joaquin County Policies, the Local Assistance Procedure Manual (LAPM), and the most recent
guidelines for the Federal Highway Bridge Program (HBP).
Expected Duration of Phase II of the PROJECT: 36 to 48 Months.

2.0 PROJECT BACKGROUND/HISTORY
Escalon-Bellota Road is a two lane roadway classified as a major rural connector. This is a critical
element of the County’s transportation system connecting agricultural lands to the south with State Route
Escalon-Bellota Road Bridge No. 29C-051 at Mormon Slough was constructed in 1966 and consists of
nine (9) spans (11’-2” each in length). The superstructure consists of reinforced concrete continuous flat
slab. The substructure consists of eight (8) reinforced concrete pile bents in which each bent contains
five (5) 12” diameter “Raymond” step-tapered pile shafts and reinforced concrete diaphragm abutments
over pile foundations. Many of the corrugated steel shell casings that were once below grade are
presently exposed. Currently, the bridge is at a stage considered scour critical and the existing
embankment near Abutment #1 and Bents #2-5 has experienced a significant amount of scour. The
migrating path of the channel toward abutment #1 has eroded the embankment to nearly a vertical cut
that makes the embankment slope unstable and susceptible to future erosion and possible complete
embankment slippage. The County has installed RSP as a temporary scour countermeasure until the
structure is replaced
Project Location: The PROJECT is located in the unincorporated County area as shown on the
attached Vicinity Map.
