CABRILLO Historic Structures Report

APPROACH

Our philosophy is that the rehabilitation, restoration, preservation or stabilization of a structure should have a minimal impact on historic fabric. Deficiencies that threaten life and safety, or that are causing deterioration must be corrected. The value of any other improvements should be weighed against the value of the building's integrity. The historic fabric and character-defining features of these structures were described earlier in this report. The following recommendations, extracted from Director's Order 28 (DO-28), Cultural Resource Management Guidelines, apply to all treatments.

• Use is monitored and regulated to minimize both immediate and long-term damage.

• Use of destructive techniques, such as archeological excavation, is limited to providing sufficient information for research, interpretation, and management needs.

• All work that may affect resources is evaluated by an historical architect and other professionals, as appropriate.

• All modification, repair, or replacement of materials and features is preceded by sufficient study and recording to protect research and interpretive values.

• New work, materials, and replacement features are identified, documented, or permanently marked in an unobtrusive manner to distinguish them from original work, materials, and features. The manner and location of identification is recorded using the Inventory and Condition Assessment Program (ICAP). The ICAP program will be updated and modernized in FY2000, and may become known under a different acronym.

• A proposed treatment project is initiated by the appropriate programming document, including a scope of work and cost estimate from an HSR or ICAP. Such projects include preservation maintenance as well as major treatment. No treatment is undertaken without an approved HSR or work procedure documenting the work, and Section 106 compliance.

• A treatment project is directed by an historical architect and performed by qualified technicians.

• Representative features salvaged from an historic structure are accessioned and cataloged, provided that they fall within the park's scope of collection statement.

• All changes made during treatment are graphically documented with drawings and photographs. Records of treatment are managed as archival materials by a curator or archivist within the park's museum collection.

As with any historic building, the State Historical Building Code and the Uniform Code for Building Conservation should be used as the prevailing codes. This allows for sensitive, performance-based means for achieving a safe, improved structure.
