e. Stormwater Management <br />1. No net increase in peak <br />flow leaving the site from <br />the predevelopment <br />conditions for the 10 year, <br />24 -hour storm; <br />2. The stormwater <br />management system must <br />respect existing drainage <br />patterns. Runoff shall be <br />directed away from <br />erosion -prone slopes. <br />3. Energy dissipaters shall <br />be used where runoff is <br />concentrated and <br />discharged, for example, at <br />downspouts from rooftops <br />and storm drains at parking <br />areas. Runoff shall not be <br />discharged directly into <br />surface water, or other <br />environmentally sensitive <br />areas; <br />4. Concentrated <br />stormwater, conveyed by <br />ditches, channels, pipes, <br />swales or other <br />conveyance systems must <br />be dispersed and diffuse <br />flow reestablished prior to <br />discharge into a stream <br />buffer; <br />5. Nitrogen load <br />contribution must be held <br />to 3.6 Ibs per acre per <br />year. <br />f. Drainage <br />1. All drainage structures <br />will be installed and <br />maintained according to <br />the approved Stormw ater <br />Management Plan. <br />PLANNING BOARD <br />RECOMMENDED <br />EVIDENCE SUBMITTED <br />FINDINGS <br />TO SUPPORT FINDINGS <br />x Yes �No <br />This condition is met with a <br />bio- retention area as <br />designed on the Erosion <br />Control Plan. <br />x Yes _No <br />The design is consistent with <br />all state Best Management <br />Practices. <br />x Yes _No Level spreaders are used and <br />the bio - retention basin to <br />insure no concentrated <br />runoff. <br />x Yes _No Use of the level spreader and <br />no work near stream buffer. <br />__x _Yes —No The nitrogen load will be <br />2.07 Ibs per acre per year. <br />x Yes ____No A grading and storm drainage <br />plan were submitted and <br />must be adhered to <br />a0 <br />BOARD OF <br />COMMISSIONERS <br />FINDINGS <br />_Yes _No <br />_Yes _No <br />Yes _No <br />—Yes _No <br />_Yes —No <br />_Yes __--.No <br />GACumnt Ranning Division \®DIMtemative SchooPAllemative School- Flndingwffact -BOCC. doc 10 <br />
