Kellogg Park Underwater Map
Location: La Jolla, Calif.
Contractor: T.B. Penick & Sons, Inc., San Diego

This unique project took four years to develop, according to Chris Klemaske, project developer. The 2600-square-foot concrete slab is located alongside the Pacific Ocean at a park for scuba divers, mapping the underwater area. "A 13-member volunteer committee provided the conceptual design for the work, involving many volunteer people and groups that included the Sycuan Band of the Kumeyaay Indian Nation and Scripps Oceanographic Institute, La Jolla, Calif., in the funding and execution for the work."

A local artist created 300 bronzes of sea animals found in the park waters, identifying them in English and the language of the Kumeyaay. The pieces were first placed on the slab to ensure they were located properly, then they were anchored to a base slab, flat and level. The top slab was placed in several placements with recycled glass broadcast and later exposed using surface retarders. The low profile exposed aggregate process is their own proprietary method. Klemaske says they used a dozen different shades of glass to create the map; greens for grass areas, browns for sandy areas, and several shades of blue and green to depict water. The project was dedicated Sept. 12, 2008.
