BASED ON A 1.5%SLOPE OF THE FEEDING STREAM CHANNEL, RAISING THE POND WATER SURFACE BY 1.5' IS EXPECTED TO INIIPACT APPROXIMATELY 100 FEET OF STREAM CHANNEL. NO MITIGATION IS REQUIRED. UTFALL STATEMENT THE NEW POND OVERLAND SPILLWAY WEIR AND EXIT CHANNEL CONNECTS TO THE EXISTING SPILLWAY CHANNEL THAT HAS BEEN CUT INTO ROCK. REFER TO SECTION B-B ON SHEET4 FOR DETAILS AND CALCULATIONS. COMPUTATIONS ON SHEET 4 INDICATE THE ADEQUACY OF THE EXISTING CHANNEL TO CONVEY THE 2, 10 AND 100-YEAR STORM FLOWS. SINCE THE SPILLWAY HAS EXISTING ROCK ASA LINER AND NO INCREASE IN STORMWATER RUNOFF IS ANTICIPATED, NO ADDITIONAL LINING IS REQUIRED AND NO SIGNIFICANT EROSION OF THE CHANNEL IS ANTICIPATED. THE EXISTING SPILLWAY CHANNEL FLOWS PARALLEL TO THE RIGHT -SIDE A 1 F EMBANKMENT FILL LINE AND FLOWS TOWARDS THE SOUTHEAST BEGINNING AT A POINT APPROXiNIATELY 40 FEET FROM THE DOWNSTREAM EMBANKMENT TOE OF SLOPE. VISUAL INSPECTION INDICATES A WELL -STABILIZED NATURAL OUTFAL L CHANNEL FROM THAT POINT DOWNSTREAM. SINCE THERE WILL BE NO INCREASE IN STORMWATrER RUNOFF FOLLOWING THIS DEVELOPMENT, NO ADDITIONAL ANALYSIS Of THE. DOWNSTREAM CHANNEL IS REQUIRED. IN THE EVENT OF A 100-YEAR STORM, THERE WILL BE AT LEAST ONE FOOT OF FREEBOARD FROM THE POND WATER SURFACE ELEVATION AND THE TOP OF DAIM. THE EXISTING SPILLWAY CHANNEL IS ADEQUATE TO CONVEY THE 100-YEAAR STORM WITHIN ITS BANKS. NO ADVERSE IMPACTS TO DOWNSTREAM PROPERTIES ARE ANTICIPATED.
