The Arboretum has its bog garden. The Center for Urban Horticulture (CUH) has its rain garden. A new rain garden is part of a larger project designed by Berger Partnership to direct rainwater from the roofs of Merrill and Isaacson Halls to the existing roof garden, an as-yet undeveloped hillside garden, and collection bins (rain gardens). When funding is found to complete the project, the CUH will present a completely integrated water system which collects rain, delivers it to the gardens, and drains to Lake Washington.
Lisa Haglund, a recent graduate with a degree Community, Environment, and Planning in the UW College of Built Environments, created the planting plan for the rain garden with guidance from the UW Botanic Gardens’ Dr. Kern Ewing, David Zuckerman and Barbara Selemon. In May, students from Maggie Rose’s Ingraham High School science classes prepared the site with Haglund and Patrick Mulligan, after Selemon arranged for Haglund to give a presentation on stormwater at their school. Ingraham currently has no available site for rain garden construction, so the Ingraham students’ trip to the CUH was funded through GROW, a program designed to engage high school students with the UW Botanic Gardens.
Lisa describes her experience working with high school students:
From the first field trip to the last, I saw an awakening interest in plants, planting, maintenance techniques, and natural systems take root in many of these young people. Through experiential learning students gained knowledge of how plants and soils act to capture and filter out the contaminants in runoff, the value of freshwater and freshwater ecosystems, and how each of them can make a difference by implementing Low Impact Development projects at their homes and schools.
