Erosion & Sediment Control: Adequate (Code Chapter 17, Article II) X Not Adequate Y N State standards followed, and Design Standards Manual notes and details Adequate limits and perimeter measures out of work areas All stages protected adequately Adequate channels MS -19 does not appear addressed with this submittal. Contour elevation numbers are not shown for trap/basin. Please show construction details for trap/Basin. Sequence of construction does not appear to match plan view. Trap is bypassed by existing stormwater pipes. Inlet protections are to be utilized in conjunction with perimeter control structures. Please show the manhole structures to receive watertight seal upon removal of existing stormwater pipes unless the pipes drain into perimeter control structures. Phase 1 and Phase 2 do not appear to match. Existing pipes in phase 1 to be removed are still existing in Phase 2 along with other "to be demolished" items. Due to incompleteness of submittal additional comments /conditions may be forth comine. Stormwater Management: (Code Chapter 17, Article III) Adequate X Not Adequate Y N ? Enough capture and treatment for on -site areas ? Enough detention storage for on -site areas x Sealed hydrologic and hydraulic computations provided Proposed drainage area 103b does not appear to be correct. Please check all drainage areas are correct. Calculation could not be matched to plans. Existing 36 "rcp appears to be missing from the stormwater profiles. There are details for bio- infiltration swale with under drain on page C8.02 that could not be located on the plan, please clarifv.
