Rain Garden/ Bioretention Basin, Omaha, NE
Client:
Lamp Rynearson Office
Lamp Rynearson employees recently took part in the creation of rain gardens (bioretention basins) on the grounds of the Lamp Rynearson office. Bioretention basins are a depressed area in the landscape designed to capture and infiltrate storm water during minor storm events. The area is planted with native grasses and flowers (some native) that tolerate the wet/dry conditions of the basin.
The primary reason to build such a rain garden is to help improve
storm water quality. Dirt, oil, trash, etc. that runs off the parking lot, as well as excess nutrients and herbicides from lawn care, is filtered through plants and soil. Plant uptake and microbial
activity also help reduce pollutants. The result is cleaner water leaving the property, and the potential to reduce irrigation needs on that side of the office building.
This demonstration project by Lamp Rynearson employees was in response to a recent City of Omaha ordinance which addresses Post-Construction Stormwater Management, and requires water quality treatment to be provided for the first ½ inch of storm runoff.
A rain garden or bioretention basin is one way to meet those requirements. This project was a hands-on exhibit for Lamp Rynearson employees, which will, in turn, benefit clients.
