The Purpose of Erosion & Sediment Control  To effectively contain sediments to a spe- CITY OF cific area; to minimize erosion; and prevent sediment from moving into streets, gut- ters, ditches, lakes, wetlands and onto your neighbors property. Erosion & Sediment  To minimize the addition of phosphorous (an element strongly bonded to sediment Control Information particles) and other contaminants to our lakes, ponds, and rivers. Keep in Mind—an for Residential Areas addition of phosphorous can lead to ex- cess algae growth!

Silt fence and straw waddles can be used to contain sedi- ment on resident’s property to keep sediment out of the lake.
