It is expected that the earthwork on this project will balance on site.The purpose of this project is the construction of Church missions building. Approximately 1.5 acres are scheduled for disturbance. ERSI N AND SEDIMENT CONTROL MEASURES: EXISTING SITE CONDITIONS:Measures shown on the accompanying drawings are to be installed in The topography of the site is relatively flat within all reaches. The area landcover is partly wooded area with an existing Church building, some accordance with the specifications and standards of the Virginia Erosion and Sedimentation Control Handbook, 3rd Edition 1992,existing parking areas and utility structures. ADJACENT AREAS:MAINTENANCE The project area is bounded by rt. 250 to the South and by unimproved or rural properties on all other sides.In general, all Erosion and Sediment control measures will be checked daily and after each significant rainFall. The following items be W will checked in particular: SOILS:a) should sediment basins or traps be required, they will be cleaned and maintained Soils in this area are generally described as Nason Silt loam. Nason are well drained with medium to rapid runoff and moderate permeability.according to the Virginia Erosion and Sediment Control Handbook b) All gravel outlets will be checked regularly for sediment buildup that CRITICAL AREAS:will prevent drainage If the gravel is clogged by sediment, it shall be Critical areas are those (such as creek channels) subject to concentrated stormflows or subsurface springs. In topography such as this,removed and cleaned or replaced c) All silt barriers will be checked regularly for undermining or deteriorationsourcecontrolofsedimentiscriticaltoerosioncontrol.
