Post-treatment Monitoring
In order to ensure the long-term preservation of the mural and the site, the Getty Conservation Institute committed to post-treatment monitoring over ten years following completion of the conservation treatment and construction of the shelter.
For the first two years (2013–2015), monitoring was carried out on a semi-annual basis to assess the effectiveness of the treatment, the performance of the shelter, roll-down screen, and viewing platform, and to track the number of visitors to the site. From 2015 to 2022, monitoring was carried out on an annual basis, and in the event of a natural disaster or other reported damage.
Objective of Monitoring
The purpose of monitoring is to detect and address any change to the condition of the mural, including the integrated shutters and door, shelter, viewing platform, and surrounding environment, and to report this to the general manager, El Pueblo de Los Angeles Historical Monument, who is responsible for maintenance and repairs at the site.
Methods
Monitoring includes visual examination of the mural, white-balanced color photo-documentation of representative control areas, graphic documentation, and an overall site inspection, including the shelter, roll-down screen, viewing platform, and adjacent roofs.
