Through multi-partner coordination and four highly attended volunteer workdays, the team installed more than 50 native plants, including five new trees.
The team collaborated with Tucson Clean and Beautiful in the planning and design phase, analyzing how water flowed through the site before any earthwork began to ensure the physical changes best complemented the site. Volunteers created rock basins, built berms, and built a Zuni bowl to capture stormwater based on the site’s natural water flow. Complementary curb cuts along the sidewalk allow additional water from the adjacent parking lot to flow into the garden, while rock overflows help direct excess water through the site.
Once earthwork was completed, volunteers planted trees and shrubs in and next to the basin. Altogether, the four workdays drew 86 volunteers, who contributed physical labor to make the project possible, while also learning about landscape design and water green storm infrastructure in the process.
These features will help reduce flooding in the adjacent parking lot, increase water infiltration, and improve the likelihood that newly established plants can eventually thrive without irrigation. The collaborative approach taken by Epsilon Eta created meaningful educational opportunities for over 80 participants and strengthened new relationships, both off and on campus.
Over the long term, the rainwater garden will reduce flooding in surrounding areas, support native wildlife, and promote biodiversity on campus.
