Castro Breen Adobe Restoration

The Castro-Breen Adobe Restoration project aims to preserve the historic integrity of the east wall of the Castro-Breen Adobe at San Juan Bautista State Historic Park in California through targeted conservation work. This includes the careful hand removal of loose and deteriorated stucco, repair of exposed wood elements within the adobe wall using Abatron epoxy, and the application of a historically accurate stucco mix via trowel and injection grouter to match original materials and methods. The six-over-six light wood window will be stripped of paint and putty, with damaged components repaired or replaced using wood of like species, followed by priming, painting, and reglazing to align with original design specifications. The entire repaired exterior wall will be finished with a compatible paint system to ensure long-term protection without compromising the adobe structure’s authenticity. All work is governed by the Secretary of the Interior's Standards for the Treatment of Historic Properties and the 1995 Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings by Weeks and Grimmer, ensuring minimal intervention and maximum retention of historic fabric. The project is managed by the California Department of Parks and Recreation through its Diablo Range District, with Gina Benigno serving as the primary point of contact for inquiries. The work is to be performed on-site at San Juan Bautista State Historic Park, and no formal contract award or pricing information is currently available, as the documentation reflects a forecasted action rather than an active solicitation. No FAR clauses, evaluation factors, payment details, invoicing instructions, or specific delivery timelines have been established in the available records. The project qualifies for categorical exemptions under California environmental regulations, streamlining approvals due to its nature as a minor alteration to a designated historic structure. While no solicitation number, contract value, or submission requirements are published, the scope is narrowly defined to preserve the building’s historic character through material authenticity, skilled craftsmanship, and adherence to nationally recognized preservation standards.
