Best Practices in Stone Building Preservation Management

The San Antonio Missions Manual of Best Practices in Stone Building Preservation Management was prepared by the University of Texas at San Antonio’s Center for Cultural Sustainability (UTSA-CCS) to provide a framework for the ongoing care and management
of the historic Spanish Colonial structures in the San Antonio Missions National Historical Park (SAAN). Based on assessments of the missions’ designations of historic significance, stated preservation objectives, and observed heritage values, this manual provides guidance to assist the National Park Service in the management of the Missions as a National Historical Park and UNESCO World Heritage site.

The Manual of Best Practices details implementation priorities and treatment protocols for stone masonry at the SAAN sites, which includes four compounds and associated features. The first and second sections of the manual focus on treatment principles and essential building health, including structural issues and site water management. The third section of the manual addresses risk management of the park’s cultural assets.
