Stormwater Management

Boulevard Park Rain Garden Project

The City of Lake Saint Louis through a grant from the Missouri Department of Natural Resources has constructed a rain garden and bioretention area demonstration project within Boulevard Park. Rain gardens slow water flow, minimize flooding, and improve water quality in rivers and lakes.

Winter Deicing Tips

The City would like to remind you that there are ways to be environmentally friendly to our lakes and streams while the temperatures are below freezing. Snow melt and stormwater runoff in areas with salt-treated surfaces such as driveways and sidewalks can carry sodium and calcium chlorides into our waterways.
