REQUEST FOR MORE INFORMATION
Dear Ms. Hilliard:
On July 23, 2007, the Division of Water Quality (DWQ) received your application dated July 10,
2007, to fill or otherwise impact 801inear feet of perennial stream, to replace an existing
concrete low water crossing with a bottomless arch culvert. The DWQ has determined that your
application was incomplete and/or provided inaccurate information as discussed below. The
DWQ will require additional information in order to process your application to impact protected
wetlands and/or streams on the subject property. Therefore, unless we receive five copies of the
additional information requested below, we will have to move toward denial of your application
as required by 15A NCAC 2H .0506 and will place this project on hold as incomplete until we
receive this additional information. Please provide the following information so that we may
continue to review your project.
Additional Information Requested:
Your proposed bottomless culvert(s) must include submittal of a signed and sealed (by a
Professional Engineer or Professional Geologist) geotechnical investigation of subsurface
soils which directly complies with the DIVISION OF HIGHWAYS -GUIDELINES
FOR DRAINAGE STUDIES AND HYDRAULIC DESIGN, PREPARED BYA. L.
HANKINS, JR., P.E.STATE HYDRAULICS ENGINEER -1999
(http•//www ncdot o~~/doh/PRECONSTRUCT/HIGHWAY/hydro/g10399web/pdf/l;uideli
nes.pdf ), which states, "When a shallow (3-5 foot max. depth) non-erosive rock
foundation is found throughout the proposed site, the structure can be built on footings
without a bottom allowing retention of the natural channel bed." The Geotechnical Unit
must confirm the foundation acceptability prior to final selection of the "bottomless"
culvert."
