12. Construction Access Routes Description A stabilized mat of aggregate underlain with filter cloth shall be located at any point where traffic will be entering or leaving a construction site or from a public right-of-way, street, alley, or parking area. Individual lots shall have their own drive once construction on the lot begins. Applicability A construction entrance shall be used: • Where construction vehicles leave active construction areas onto surfaces, • Where runoff is not intercepted by sediment controls, • At all points of egress from the construction site to public roads, and • Where frequent vehicle and equipment ingress/egress is expected. Design Guidelines Bedding A geotextile cloth shall be placed over the entire area prior to placing stone. It shall have Grab Tensile Strength of at least 200 lbs. and Mullen Burst Strength of at least 190 lbs. Stone Two-inch stone shall be used, or recycled concrete equivalent. The stone layer shall be at least 6 in. thick. Length – Width The construction entrance shall be as long as required to stabilize high traffic areas, but not less than 50 ft. (for single residence lots a 30 ft. minimum length applies). The entrance shall be at least 10 ft. wide, but not less than the full width at which ingress/egress occurs. Culvert A pipe or culvert shall be placed under the entrance if needed to prevent surface water form flowing across the entrance or from being directed onto a public road. Water Bar A water bar shall be constructed as part of the construction entrance if needed to prevent surface runoff form flowing the length of the construction entrance and out onto public roads or existing paved surfaces. Maintenance Top dressing of additional stone shall be applied as conditions demand. Mud spilled, dropped, washed, or tracked onto public roads, or any surface where runoff is not intercepted by sediment controls, shall be removed immediately. Removal shall be achieved by scraping or sweeping. Third Edition Stormwater Standards Manual September 2008 Page 173
