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
