1 <br /> Metal fences shall be designed and installed according to the manufacturer's spe- <br /> cifications. <br /> Metal fences shall be at least 3 feet high and must be highly visible. <br /> Fences shall not be wired or stapled to trees. <br /> Maintenance Standards ' <br /> If the fence has been damaged or visibility reduced, it shall be repaired or replaced <br /> immediately and visibility restored. <br /> BMP C1 5: Stabilized ConstructionEntrance 1 Exit <br /> Purpose <br /> Stabilized Construction entrances are established to reduce the amount of sediment , <br /> transported onto paved roads by vehicles or equipment. This is done by constructing a <br /> stabilized pad of quarry spalls at entrances and exits for construction sites. 1 <br /> Conditions of Use <br /> Construction entrances shall be stabilized wherever traffic will be entering or leaving a 1 <br /> construction site if paved roads or other paved areas are within 1,000 feet of the site. <br /> For residential construction provide stabilized construction entrances for each residence, 1 <br /> rather than only at the main subdivision entrance. Stabilized surfaces shall be of suf- <br /> ficient length/width to provide vehicle access/parking, based on lot size/configuration. <br /> On large commercial, highway, and road projects,the designer should include enough <br /> extra materials in the contract to allow for additional stabilized entrances not shown in <br /> the initial Construction SWPPP. It is difficult to determine exactly where access to these I <br /> projects will take place; additional materials will enable the contractor to install them <br /> where needed. <br /> Design and Installation Specifications <br /> � p <br /> See Figure II-4.1.1 Stabilized Construction Entrance (p.273)for details. Note: the 100' , <br /> minimum length of the entrance shall be reduced to the maximum practicable size when <br /> the size or configuration of the site does not allow the full length (100'). <br /> Construct stabilized construction entrances with a 12-inch thick pad of 4-inch to 8-inch <br /> quarry spalls, a 4-inch course of asphalt treated base (ATB), or use existing pavement. <br /> Do not use crushed concrete, cement, or calcium chloride for construction entrance sta- ' <br /> bilization because these products raise pH levels in stormwater and concrete discharge <br /> to surface waters of the State is prohibited. <br /> 2014 Stormwater Management Manual for Western Washington <br /> Volume 1l- Chapter 4 -Page 270 1 <br />
