Chapter 5: Stormwater Management

The use of stormwater management, erosion control, and sediment control tools provide a direct return on investment to communities and landowners by reducing future costs from flooding and erosion. For example, erosion costs might come
in the form of streambank stabilization projects required to protect property and infrastructure (e.g. pipelines, bridges, or homes); flooding costs might come in the form more frequent and higher floods, which can adversely impact property and infrastructure.

Better stormwater management means cleaner local waterways and fewer costs from polluted waters. Improved stormwater management might limit the need for waste water treatment plant upgrades. The preservation and restoration of natural drainage features provides for a lower-cost, lower maintenance alternative to higher-cost, increased-maintenance, man-made structural BMPs. However, a combination of structural and non-structural BMPs through good site design and construction site management along with local, county and/or regional land use planning (e.g. floodplain management) will be most effective.
