PROPOSED IMPROVEMENTS:
THE PROPOSED DEVELOPMENT INCLUDES THREE OFFICE BUILDINGS ON CONCRETE SLABS WITH
PITCHED ROOFS. THE PARKING AND DRIVE ISLES WILL BE 2" ASPHALT OVER 6" GRAVEL BASE
WITH 2'-6" CONCRETE CURB AND GUTTER.
SITE CON71DMONS-
SITE VEGETATION IS SPARSELY TO HEAVILY WOODED WITH MATURE LOBLOLLY PINES, JUNIPERS
AND OAKS. THE AVERAGE GROUND ELEVATION IS 12.0' M.S.L. WITH THE WATER OBSERVED AT
7' M.S.L. SEASONAL HIGH WATER TABLE ESTIMATED TO BE 9' BASED ON SOIL CHROMA AND
ACCOUNTS FROM NEIGHBORS OF WATER LEVELS IN THE NCDOT DITCH ALONG THE SOUTH
PROPERTY LINE. SITE SOILS ARE CnA (CONETOE) LOAMY SAND WELL DRAINED WITH RAPID
PERMEABILITY (6"-20"/hr), Ds (DRAGSTON) LOAMY FINE SAND SOME WHAT POORLY DRAINED
SOIL WITH MODERATELY RAPID PERMEABILITY (6 in/hr), AND Pt (PORTSMOUTH) FINE SANDY
LOAM VERY POORLY DRAINED SOIL WITH MODERATE PERMEABILITY (1 in/hr). THE NORTH EAST
CORNER OF THE PROPERTY IS PORTSMOUTH, THE CENTER OF THE SITE INCLUDING THE AREA
OF THE PROPOSED WET BASIN IS DRAGSTON AND AN ACRE ALONG U.S. 158 IS CONETOE. SITE
SOILS HAVE LOW SHRINK -SWELL POTENTIAL.
MANAGEMENT NARRATIVE:
STORMWATER IS COLLECTED FROM THE PARKING AREAS AND STREET BY CATCH BASINS AND
DIRECTED BY PIPE TO THE FOREBAY OF A WET DETENTION BASIN. THE COVERAGE ALLOWED BY
CURRITUCK COUNTY U.D.O. IS 65%. PROPOSED COVERAGE IS 52.4%.
THE WET DETENTION BASIN IS SIZED AND CONFIGURED TO PROVIDE SIGNIFICANT REMOVAL OF
POLLUTANTS FROM INCOMING STORMWATER RUNOFF. BAFFLES CONSTRUCTED FROM SHEET
PILES WITH A CONCRETE CAP HAVE BEEN PLACED IN THE WET DETENTION BASIN TO LENGTHEN
THE STORMWATER FLOW PATH AND PREVENT SHORT CIRCUITING. THE PERMANENT POOL OF
WATER IS DESIGNED FOR 90% TSS POLLUTANT REMOVAL EFFICIENCY. A 6:1 SUBMERGED
VEGETATED SHELF 10' WIDE IS LOCATED BELOW THE PERMANENT POOL ELEVATION. VEGETATIVE
COVER ABOVE THE PERMANENT POOL ELEVATION SHALL BE SOD.
A 120' DRAINAGE EASEMENT WILL BE RECORDED THAT IS 120' WIDE AT THE BASIN AND 45'
WIDE EXTENDING TO CARATOKE HIGHWAY. DRAINAGE OF THE BASIN FOR MAINTENANCE OR AN
EMERGENCY WILL BE BY SUMP PUMP WITH A 10" DISCHARGE LINE,

5. Surface Water - all surface water flowing to or diverted toward construction
entrances shall be piped through the entrance, maintaining positive drainage. Pipe
Installed through the stabilized construction entrance shall be protected with a
mountable berm with 5:1 slopes and a minimum of 6" of stone over the pipe. Pipe has
to be sized according to the drainage. When the SCE is located at a high spot and
has no drainage to convey a pipe will not be necessary. Pipe should be sized
according to the amount of runoff to be conveyed. A 6" minimum will be required.
6. Location - A stabilized construction entrance shall be located at every point
where construction traffic enters or leaves a construction alto. Vehicles leaving
the site must travel over the entire length of the stabilized construction entrance.
