Chapter 4 - Best Mana ement Practices for Erosion and Sediment Control <br /> 4 . 04 CONSTRUCTION ROAD STABILIZATION <br /> ( ES BMP 1 . 02 ) <br /> Definition <br /> The temporary stabilization of access roads , subdivision roads , parking areas , and other <br /> on-site vehicle transportation routes with stone immediately after grading . <br /> Purposes <br /> 1 . To reduce the erosion and degradation of temporary roadbeds by construction <br /> traffic, especially during wet weather. <br /> 2 . To reduce the erosion and minimize regrading of permanent roadbeds between the <br /> time of initial grading and final stabilization . <br /> Conditions Where Practice Applies <br /> .r <br /> Wherever stone-base roads or parking areas are constructed , whether permanent or <br /> temporary, for use by construction traffic. <br /> Planning Considerations <br /> Areas which are graded for construction vehicle transport and parking purposes are <br /> especially susceptible to erosion . The exposed soil surface is continually disturbed , leaving <br /> no opportunity for vegetative stabilization . Such areas also tend to collect and transport runoff . <br /> waters along their surfaces . During wet weather, they often become muddy quagmires which <br /> generate significant quantities of sediment that may pollute. nearby streams or be transported <br /> off-site on the wheels of construction vehicles . Dirt roads can become so unstable during wet <br /> weather that they are virtually unusable. r„ <br /> •w t 1 <br /> ^ 11111 <br /> NH �I I • < � 6 ..+f <br /> wn <br /> .�� IFII �sla.C.a. tet. <br /> OlA Ir • kr• • •^ <br /> ej <br /> S — to <br /> E W X <br /> Jw .• .a <br /> 4- 11 <br /> r <br />
