Historic Resources Survey for Castro Valley
I. STATEMENT OF WORK
A. INTENT
The Alameda County Planning Department is pursuing a multi-phased project to conduct
a comprehensive historical survey of Unincorporated Alameda County. This Informal
Request for Proposal (IRFP) includes the preparation of a Historic Context Statement
(HCS), a Reconnaissance Level survey, and Intensive Survey in areas of Castro Valley. The
goal of the project is to update the County's list of historical resources and identify new
or previously undocumented resources of potential historic significance.
The County intends to award a two-year contract for the project not to exceed $80,000.
B. SCOPE
The County is seeking assistance from a Contractor(s) with the experience, capacity, and
skills necessary to:
1. Prepare a Historic Context Statement for Castro Valley, using previous surveys,
plans, and evaluations as a foundation (EXHIBIT B).
2. Conduct a Reconnaissance-Level Survey in Castro Valley, targeting areas that contain
properties 45 years of age or older, and prioritizing the oldest structures including,
but not limited to residences, barns, water towers, etc.
3. Conduct an Intensive Survey and prepare California Department of Recreation 523
forms for up to 25 properties determined to be the most historically significant.
4. Prepare a Summary Report.
The Contractor(s) will be expected to work closely with County staff from the Planning
Department and the Parks, Recreation, and Historical Commission (PRHC) as necessary.
The ideal Contractor(s) will have demonstrated familiarity with professional historic
resource surveys, architectural history, historic preservation planning, or related cultural
resource management services, and the diverse communities of unincorporated
Alameda County. Consideration will be given to the proposal that outlines the most
efficient and cost-effective way to perform the work and provide the services described
in this IRFP.
County staff welcomes respondents to propose revisions or alternatives to the scope of
work that would improve efficiency, cost-effectiveness, or overall project feasibility. Due
to current budget limitations, surveying all qualifying properties in Castro Valley -
estimated at approximately 13,000 - may not be feasible. Proposals should clearly
define a realistic and appropriate sample size and scope consistent with available

resources and costs for completing the survey of remaining properties. A phased
approach may also be considered, pending future available funding.
Staff has also identified optional tasks that may be undertaken if budget allows. If a
Bidder is unable to include these optional tasks within their proposed budget, the
response should identify and provide the estimated cost to complete each optional task
separately that may be accommodated should additional funding become available.
C. BACKGROUND
The Alameda County Community Development Agency's Planning Department
("Planning Department") serves the unincorporated communities of Alameda County,
which include Ashland, Castro Valley, Cherryland, Fairview, Hayward Acres, San Lorenzo,
Sunol, and the rural east county communities outside the cities of Livermore, Dublin,
and Pleasanton. The Planning performs municipal-type land use regulation functions,
including historic preservation, for unincorporated areas of the County, ensuring
compatible land use for the roughly 152,000 residents within its jurisdiction.
The PRHC was established by the Board of Supervisors to assist in the protection,
preservation, and promotion of historic resources within unincorporated Alameda
County. It is comprised of volunteer community representatives appointed by the Board
of Supervisors. It advises the Boards of Zoning Adjustments, Planning Commission and
Board of Supervisors on recreation and parks issues in Alameda County.
The County has conducted four historic surveys in the unincorporated areas:
* Preliminary Cultural Resources Survey of Ashland and Cherryland Districts (1998)
* Unincorporated San Lorenzo Historical Building Survey (2000)
* Historical and Cultural Resources Survey: East Alameda County (2005)
* Unincorporated Alameda County Historic Survey Report (2008)
The 2008 project included a windshield survey of historic properties built before 1960 in
the unincorporated communities of Fairview, Hayward Acres, Hillcrest Knolls,
Fairmount, El Portal Ridge, and the Castro Valley canyons. The survey results were
compiled into a database together with properties identified in the three previous
historical surveys. This database became the foundation for Alameda County's historic
inventory, which currently includes 169 resources - 53 of which are located in Castro
Valley.
In addition to the survey, the 2008 project also involved the preparation of a historic
context statement for the County and a Historic Preservation Ordinance (HPO). The
Alameda County Board of Supervisors adopted the HPO in 2012. The ordinance
RFP No. PLN 2026-001

Specifications, Terms & Conditions
Historic Resources Survey for Castro Valley
established the Alameda County Register of Historic Resources and describes how
properties may be added or removed from the register. There are 17 resources listed on
the County Register - eight of which are located in Castro Valley.
Additional historic surveys have been a longstanding priority for the PRHC. In December
2024, Planning Department staff conducted an analysis of properties in the
unincorporated areas and identified nearly 30,000 structures that are 50 years or older
- a common threshold for potential historic significance. Based on this analysis, the
PRHC directed staff to focus the next historic survey on Castro Valley, which contains
the highest concentration of potentially historic properties (approximately 13,000) and
has not been the subject of previous surveys. The PRHC has also expressed an interest in
prioritizing the oldest structures, including residences, barns and water towers.
The Background Information in Exhibit B includes links to the County documents that
will be relevant for Bidders in developing a bid response to this IRFP.
