With the retirement of the Philadelphia Zoo's historic Pachyderm habitat, and transformation into the new Hamilton Family Children's Zoo, Mara Restoration was brought in by W.S. Cumby to perform a variety of masonry repairs and restorations. Included in the work was masonry cleaning, repointing, repairing and replacement, plus the demolition and rebuild of an existing retaining wall. This project marks the second collaboration of Mara Restoration and the Philadephia Zoo.
