<br />In Northeastern Illin ois <br /> <br />Farm practices such as terracing and no-till help reduce agricultural erosion and keep <br />topsoil where it is needed. Techniques such as silt fences can greatly reduce the <br />possibility of soil loss form construction sites. Sediment traps installed downstream of <br />construction sites slow runoff so sediment is dropped on-site before it gets to the water <br />courses. The key is to get these measures used, particularly on construction sites or at <br />the downstream end of plowed fields. <br /> <br /> <br />Use of a Vegetative Filter to Protect a Waterway <br /> <br />I\i<~ VE~rAT7Ye . ;,...... <br />~ 577f/1" . _-n, <br /> <br /> <br />.::weA'$'ON <br /> <br />.5{,sr/$ WA~WAY --/ <br /> <br />Source: Procedures and Standards for Urban Soil Erosion and Sediment Control, page 6-57 <br /> <br /> <br />Appropriate for: All watersheds, <br /> <br />Problems: As with any regulatory program, the community must have the staff to <br />educate developers and property owners, to monitor compliance, and to enforce the <br />requirements. <br /> <br />For more information: Soil and Water Conservation Districts, the Natural Resources <br />Conservation Service, and NIPC provide technical advice.
