Quick facts:

In October 2011, a 750 square foot raingarden was installed at the St. Mary’s of the Lake Church in White Bear Lake to capture stormwater from the property’s structural and paved surfaces.

Funding:

Project funding was helped in part by a Clean Water Fund grant with the help of the Ramsey Conservation District.

Reason for project:

The raingarden was found in a study used to identify optimal best management projects that would reduce stormwater in the Lambert Creek subwatershed.

Construction:

The Project removed existing and compacted soils to install a 12” layer of amended soils in the infiltration basin, surrounded with a retaining wall. The inlet features an 8 cubic foot pretreatment chamber to collect sediment and objects from entering the basin, simplifying maintenance.

Results:

The basin has proved to effectively capture and infiltrate stormwater from St. Mary’s of the Lake Church, and the native vegetation has grown in well and continues to flourish.
