THE DRAINAGE CALCULATIONS SHOULD REFERENCE THE SAME | | | VERTICAL DATUM AS THE PLANS (NAVD1988). | | | | | | 2. DRAINAGE CALCULATIONS SHOW A 1" RISE IN THE 25-YEAR | | | 3-DAY PEAK STAGE. DESIGN A PERIMETER BERM TO CONTAIN | | | THIS STAGE INCREASE TO THE PROJECT AREA OR PROVIDE | | | ADDITIONAL ONSITE STORAGE TO LOWER THE PEAK STAGE TO | | | EXISTING CONDITIONS. | | | | | | 3. THE SWALE ON THE LEFT SIDE OF SECTION A-A ON SHEET | | | PDD-1 IS SHOWN TO HAVE A SIDE SLOPE OF 20:1 SLOPE | | | BETWEEN THE SWALE CENTERLINE AND THE MATCHING SLOPE | | | ALONG THE EDGE OF THE SECTION. THE PROPOSED SWALE | | | CENTERLINE SPOT GRADES OF 14.9 AND 14.7 APPEAR TO BE | | | HIGHER THAN THE EXISTING GRADES TO THE WEST OF THE | | | SWALE. | | | | | | 4. THE SPOT GRADES OF 15.4 AND 15.2 FOR THE CENTERLINE | | | OF THE EAST SWALE APPEAR TO BE ABOVE THE MATCHING GRADE | | | ALONG THE EAST SIDE OF THE SWALE. | | | | | | TRACY L.
