Celebration Garden was designed by artists Marilyn Brame, Misha Ma'Heo, Aileen May, Dru Maurer, Sophia Imai, Liz Canales, Greg Nelson, Bob Knoke, Alisha Mather, students of the Visual Arts School, Cal State Fullerton art students, and Mission Viejo children. The garden reflects 10 years of Tierra Nativa, the celebration of Earth Day, Arbor Day, National Trails Day, Volunteer Connection Day, and Imagination Celebration held 1997-2006. Each pillar represents the theme for each year. Pillars were constructed from masonry blocks; recycled concrete from the City's sidewalk replacement project was used on the base of the pilasters and stained with fertilizer. Marisa Herman designed the "Unity Mosaic of Hands" at the culmination of the project, symbolizing the diversity of the Mission Viejo community. The garden path, constructed of recycled City sidewalks, was transformed by hundreds of volunteers who worked to leave an artistic legacy for the community, now and for years to come.
