CINCINNATI ZOO

Summer 2008 - Ohio River Foundation (ORF) and the Cincinnati Zoo & Botanical Garden have completed the installation of 4,000 square feet of rain gardens at the Zoo’s Harold C. Schott Education Center. This is the largest rain garden installation on any property in the tri-state area. Funding for the project was provided by Aveda, Inc. and Hamilton County Stormwater District.

Completed in stages during the summer, staff and volunteers from ORF, the Zoo, and Aveda raked, tilled and planted the rain gardens which are designed to reduce the amount of stormwater pollution entering the Metropolitan Sewer District sewer system. The gardens receive water from redirected downspouts from the Education Center and parking lot runoff. The gardens also serve as an experiment so researchers can see what plants function best in a rain garden setting.

“We are excited by the opportunity to partner with the Zoo on this important project. This is one of several high visibility rain garden installations that we are planning in the Ohio River watershed to spur development of community stormwater pollution reduction programs,” said Rich Cogen, Executive Director, ORF.

Zoo and Ohio River Foundation staff members work on rain garden that receives rainwater runoff from the parking lot via several 2-foot wide curb cuts.

EDEN PARK, OH

November 2007 - Ohio River Foundation, Cincinnati Park Board, and National City Bank completed the installation of a 500 sq. ft. rain garden in Eden Park at the Martin Road field below the reservoir. The goal is to capture flow from a 10-acre ball field before it enters a parking lot and storm sewer system. Due to the approximate 1% grade, compact clay soils, and slow flows from the field a shallow garden of only 18 inches was constructed. Runoff from the field has been noticeably reduced and lower flow volumes into the parking lot during and after rain events has been observed.

ORF, National City Bank, and Cincinnati Park staff and volunteers stage and install rain garden plants.
