CHAPTER 3 - SITE ACCESS This chapter addresses site access during actual construction of a proposed project. It should be noted that site access for site preparation work (e.g. surveying, exploration drilling, etc.) should follow the same general principals. When it becomes necessary to remove vegetative cover or cross surface waters to conduct a survey, or complete required exploration drilling and sampling, appropriate BMPs must be provided to protect the surface waters. BMPs not addressed in this chapter may be reviewed by the Department on a case-by-case basis and approved if they are found to be equal to, or better than, the following BMPs. ROCK CONSTRUCTION ENTRANCE - Sediment Removal Efficiency: LOW. This device is not an ABACT for special protection watersheds. A rock construction entrance should be installed wherever it is anticipated that construction traffic will exit the project site onto any roadway, public or private. Access to the site should be limited to the stabilized construction entrance(s). Lake County Stormwater Management Department, Ohio A geotextile underlayment should be placed over the existing ground prior to placing the stone. At a minimum, rock construction entrances should be constructed to the dimensions shown on Standard Construction Detail #3-1. Where site conditions warrant, it may be necessary to extend the length or width of the rock to ensure the effectiveness of the entrance. Wherever access to the site is across a roadside ditch, stream channel, natural drainage course, etc., a suitable means of conveying the flow past the entrance (e.g. a properly sized culvert pipe) should be provided. For such installations, a mountable berm is recommended to prevent crushing the pipe. Rock construction entrances should be maintained to the specified dimensions and the capacity to remove sediment from the tires by adding rock when necessary. For some sites this could occur several times a day. A stockpile of rock material should be maintained on site for this purpose. It should be noted that occasionally the rock construction entrance can become too clogged and might have to be removed and replaced. 363-2134-008 / March 31, 2012 / Page 13
