1 INTRODUCTION
Padre Dam Municipal Water District (Padre Dam or District) is requesting proposals from qualified
engineering firms to prepare plans for the relocation of several water facilities that will be
impacted by the County of San Diego's Riverford Roundabout project. The County of San Diego
(County) is in the final design phase of its project to reconfigure the intersections and ramps at
the SR67 and Riverford Road intersections. The District currently owns and maintains 8", 12", and
36" water transmission mains and a turnout facility that will be impacted by the project.
Relocation of these District facilities will be necessary to accommodate the changes to the
intersections and crossing. The scope of work includes, but is not limited to, identifying new
alignment options and locations for the facilities, as well as completing the final design in
conformance with San Diego Water Agency Standards (WAS), American Water Works Association
(AWWA) standards and other District operational standards.
The selected firm will provide professional engineering services to evaluate new pipeline
alignments and site the relocated turnout in coordination with the County's project. Additionally,
final design plans and specifications are to be prepared for public bidding anticipated to be
concurrent with the County project. The selected firm or team must have experience in providing
all the required engineering services including, but not limited to, project administration,
hydraulic modeling, water system design, electrical, instrumentation/controls, SCADA, and right-
of-way services. Due to the project schedule, the selected firm should be prepared to begin work
immediately upon award of contract. There will be a non-mandatory pre-proposal meeting at
9:00 am on July 7, 2026. The meeting will be held at the District's office located at 9300 Fanita
Parkway, Santee, CA 92071. Attendees should allow for 1 hour for the meeting. Questions shall
be directed in writing to: Tom Bloomer, P.E. at tbloomer@padre.org. All inquiries shall be
received by 5:00 pm on July 20, 2026. Questions and responses will be posted to Padre Dam's
website.
2 DISTRICT DESCRIPTION
Padre Dam is a public agency, a Special District of the State of California that provides water,
wastewater, recycled water and recreation services to residents in East San Diego County
including Santee, El Cajon, Lakeside, Flinn Springs, Harbison Canyon, Blossom Valley, Alpine,
Dehesa, and Crest. Padre Dam serves 100,000 residents with over 24,000 active service
connections, manages over $700 million in infrastructure assets.
Currently, the potable water system includes 3 imported water connections, 28 water storage
reservoirs, 16 booster pumping stations, 20 pressure-regulating stations, and approximately 390
miles of pipeline up to 60-inches in diameter.

3 BACKGROUND
Padre Dam's water service area is split into two geographic regions, the Western Service Area (WSA)
and Eastern Service Area (ESA). Movement of water between the two service areas relies heavily
on a large 36" water transmission pipeline that will be impacted by the County's project. This
main is commonly referred to as the El Capitan pipeline. In addition to impacts to the El Capitan
pipeline, one of the District's turnouts on Woodside Avenue will be impacted. The turnout
(Turnout No. 5) is used to meter and move water from the El Capitan main to the Gravity system
which serves customers in the WSA. This turnout distributes water both to the north and south
of SR-67 through Woodside Avenue and Riverford Road. The downstream mains served by the
turnout will also be impacted by the County's project and will need to be relocated.
The new roundabouts are to be located both North and South of existing on- and off-ramps to SR-
67 at Riverford Road and will require a substantial amount of grading. Grading work will result in
a finished surface approximately 8 to 10 feet lower as compared to the existing finished surface.
Drainage in the vicinity of the project will be revised to accommodate the new grading and will
include new and relocated County drainage infrastructure and introduce post-construction
treatment BMPs. In addition to elevation changes, revised horizontal alignments of both Riverford
Road and Woodside Avenue are necessary to accommodate the roundabout geometric features.
The project will also require revisions to other third-party utilities located within the project
footprint including County Sewer, Helix Water District facilities, and other dry utilities.
4 PROJECT DESCRIPTION
The relocation of water facilities within the immediate vicinity of the County project is necessary
to maintain transmission and distribution of water in and through the WSA. The relocation of
these critical facilities must adhere to minimum California State Water Resources Control Board -
Division of Drinking Water (DDW) separation requirements and account for future access and
maintenance activities. The El Capitan pipeline in the vicinity of the project is located within
County right-of-way, was installed in the 1930s, and is steel lock-bar pipe. The relocation of a
District turnout connected to the El Capitan pipeline will need to maintain close proximity to the
water transmission pipelines within Woodside Avenue south of SR-67 and within Riverford Road
crossing SR-67. The turnout will need to maintain connectivity with the District's SCADA system
post-construction. The other 8-inch and 12-inch mains that are impacted include mains on
Woodside Avenue and Riverford Road. A portion of the smaller diameter relocated main(s) will
be within Caltrans right-of-way and the final relocation of the turnout is to be determined.
The expected siting of replacement facilities would likely limit the relocated turnout facility to be
within the County of San Diego right-of-way where feasible or on Caltrans or on County owned
property. New easements and/or encroachment agreements may be necessary to accommodate
relocated infrastructure. The County of San Diego has requested that all relocations are to be
completed prior to the County starting the construction phase for the Roundabout project. Due
