319 Grant– Planting the Bioretention and Raingarden Cells
319 VIDEO – Building the Bioretention and Raingarden Cells
Watch our video about this three year project to improve
stormwater at the Grissum Building and Power Plant site.
Work to complete the Bioretention and Raingarden started on a sunny, 78 degree morning. By lunch time, the temperature was dropping quickly as a cold front blew through. The folks volunteering to plant hung in there to get more than 2000 plants in the ground as the temperature dropped more than 25 degrees and it started to rain. Thanks to the hearty Public Works volunteers below who helped out.

The final phase of construction for the bioretention and raingarden is the most critical: installation of native plants. Native plants are better able to withstand the brutal extremes of Missouri weather. Native plants also tend to root more deeply insuring that stormwater runoff has more avenues to infiltrate into the ground below. Native plants will use stormwater runoff and some of the nutrients that come with it, reducing the negative impacts of urban stormwater runoff from our downstream waterways. Keeping excess runoff, sediment, nutrients and other pollutants in the bioretention and raingarden cells keeps our streams healthier and cleaner.

Jim Thaxter plants Little Bluestem on the slopes adjacent to the Bioretention.
Tom Wellman plants Little Bluestem near the inlet flume to the Bioretention.

The H-flume will be used to monitor the bioretention area. One flume is placed on the inlet into the bioretention area to see how much runoff and pollution is going into the treatment feature. One flume at the outlet of the bioretention area to measure how much runoff and pollution is removed.
By measuring the runoff and sampling water before and after the retrofit BMP, we can determine how much runoff and pollution reduction is achieved using these practices.
Information gathered from the monitoring and testing will inform local engineers on the effectiveness of these treatments for storm water runoff.
