Demonstration Projects: Brentwood
Mount Calvary Rain Garden

The Mount Calvary Rain Garden is one of three demonstration projects the Metropolitan St. Louis Sewer District is implementing in the Deer Creek Watershed in collaboration with a team of Deer Creek Watershed Alliance Partners.


Located on the property of Mount Calvary Lutheran Church in Brentwood, Missouri, the Mount Calvary Rain Garden is a 3,000 sq. ft. bioretention system consisting of over 10,000 sq. ft. of native plants. The rain garden is designed to catch and slow the movement of stormwater from the church property into Deer Creek.

In 2010, Washington University monitored water quality at this site to obtain baseline data, and will conduct several years of follow up monitoring after the rain garden is installed in 2011 to measure the project’s effectiveness in improving water quality.

The maintenance of the garden is to be conducted by the Mount Calvary Church Garden Action Team.
