Florida Erosion and Sediment Control Inspector's Manual <br /> Washin <br /> If conditions on the site are such that most of the mud is not removed by the vehicles traveling <br /> over the gravel , then the tires of the vehicles must be washed before entering a public road . <br /> Wash water must be carried away from the entrance to a settling area to remove sediment <br /> r (See Plate 4 . 03b ) . A wash rack may also be used to make washing more convenient and <br /> effective (See Plate 4 . 03c) . <br /> Location <br /> The entrance should be located to provide for maximum utility by all construction vehicles . <br /> Construction Specifications <br /> .. The area of the entrance should be cleared of all vegetation , roots, and other objectionable <br /> material . A geotextile should be laid down to improve stability and simplify maintenance . The <br /> gravel shall then be placed over the geotextile to the specified dimensions . <br /> Any drainage facilities required because of washing should be constructed according to <br /> approved specifications . If wash racks are used , they should be installed according to <br /> +. manufacturer's specifications . <br /> Maintenance <br /> The entrance shall be maintained in a condition which will prevent tracking or flow of mud onto <br /> public rights-of-way. This may require periodic top dressing with 2-inch (5 cm ) stone , as <br /> conditions demand , and repair and/or clean out of any structures used to trap sediments . All <br /> materials spilled , dropped , washed , or tracked from vehicles onto roadways or into storm <br /> drains must be removed immediately . Look for signs of trucks and trailered equipment <br /> '■' "cutting corners" where the gravel meets the roadway . Sweep the paved road daily for <br /> sediments and stone . <br /> Plate 4. 03c Construction Entrance with Wash Rack <br /> Source : 1983 Maryland Standards for Soil Erosion and Sediment Control <br /> r <br /> rrs <br /> 4- 10 <br />
