Plan excavation or grading for when the weather will be dry. Contact your Water and Soil Conservation District or the Dept. of Capital Asset Management for more ways to control erosion. Keep it clean - A clean and compliant construction or business site will help prevent clutter and spills. Keep spill clean-up kits handy to use quickly, and avoid washing chemicals and oil down the sewer. Regular sweeping around the site will also help keep contaminants out of run-off storm water.
Tree roots allow the soil to absorb more water, also reducing run-off.
Trees also increase property value and reduce energy costs. Don't connect - If you install or maintain downspouts or sump pumps, make sure they do not connect to either the sanitary system or combined sewer systems. Inspect - If you inspect houses or businesses for purchase, alert your client to any downspout or sump pump connections to sanitary or combined sewers. These connections may be illegal. Check your local ordinances.
