PROPOSED IMPERVIOUS AREA IS GREATER THAN EXISTING, HOWEVER NEWLY CREATED IMPERVIOUS SURFACES SHALL BE DIRECTED TOWARDS THE STREET. LESS TOTAL AREA AND LESS IMPERVIOUS AREA WILL RUNOFF TO ADJACENT PROPERTIES IN THE PROPOSED SCENARIO. SEDIMENT CONTROL PRACTICES MUST BE ESTABLISHED ON ALL DOWN GRADIENT PERIMETERS BEFORE ANY UPGRADIENT LAND IMPERVIOUS CALCULATIONS: DISTURBING ACTIVITIES BEGIN. THESE PRACTICES SHALL REMAIN IN EXISTING IMPERVIOUS SURFACE = 2,539 SF PLACE UNTIL FINAL STABILIZATION HAS BEEN ESTABLISHED. PROPOSED IMPERVIOUS SURFACE = 2,831 SF ALL STORM DRAIN INLETS MUST BE PROTECTED BY APPROPRIATE BMPS DURING CONSTRUCTION UNTIL ALL SOURCES WITH POTENTIAL FOR DISCHARGING TO THE INLET HAVE BEEN STABILIZED. TEMPORARY SOIL STOCKPILES MUST HAVE SILT FENCE OR OTHER EFFECTIVE SEDIMENT CONTROLS, AND CANNOT BE PLACED IN SURFACE WATERS, INCLUDING STORMWATER CONVEYANCES SUCH AS CURB AND GUTTER SYSTEMS, OR CONDUITS AND DITCHES UNLESS THERE IS A BYPASS IN PLACE FOR THE STORMWATER. VEHICLE TRACKING OF SEDIMENT FROM THE CONSTRUCTION SITE MUST BE MINIMIZED BY A ROCK CONSTRUCTION ENTRANCE. STREET SWEEPING MUST BE USED IF THE ROCK ENTRANCE IS NOT ADEQUATE TO PREVENT SEDIMENT FROM BEING TRACKED ONTO THE STREET. TEMPORARY DE -WATERING - DEWATERING OR BASIN DRAINING (E.G., PUMPED DISCHARGES, TRENCH/DITCH CUTS FOR DRAINAGE) RELATED TO THE CONSTRUCTION ACTIVITY THAT MAY HAVE TURBID OR SEDIMENT LADEN DISCHARGE WATER MUST BE DISCHARGED TO A TEMPORARY OR PERMANENT SEDIMENTATION BASIN ON THE PROJECT SITE WHENEVER POSSIBLE.
