Re: Stream Origin Determination (GMI Project Area A): MCAS Cherry Point, Havelock,
NC.
Dear Roberto:
Geo- Marine, Inc. (GMI) is pleased to submit this Stream Origin Determination packet for MCAS
Cherry Point Project Area A for your review. Included in this packet are the following items:
1) Project description for MCAS Cherry Point GMI Project Area A.
2) Stream Origin Determination Methodology
3) Figures including: Subject stream origins and non - subject WoUS origins over USGS
topographic maps and USDA soil survey maps.
4) NCPLS Origins Table.
We appreciate the opportunity to work with you and the other Washington Regional Office
DWQ personnel. Please contact us if you have any questions regarding the information we have
provided.
Sincerely,
Jason C. Hales

Project Description
GMI was contracted by Naval Facilities Engineering Command (NAVFAC) Washington,
to conduct a wetland delineation and stream origin identification at Marine Corps Air Station
(MCAS) Cherry Point in project areas identified by MCAS Cherry Point. The site is located off
US Route 70 and Highway 101 in the town of Havelock, NC. NCDWQ has identified 6
intermittent stream origins and 10 perennial stream origins that are subject to the Neuse River
buffer rules in Project Area A (Figures 1 through 13 and the NCPLS Origins Table). USACE
has verified 23 additional WoUS features that are not subject to the Neuse River buffer rules in
Project Area A (Figures 1 through 13 and the NCPLS Origins Table).
Stream Origin Determination Methodology
Origins of intermittent and perennial streams were located using the Methodology for
Identification of Intermittent and Perennial Streams and Their Origins, North Carolina Division
of Water Quality (NCDWQ 2010). Project Area A was divided into four smaller areas (Al, A2,
A3, and A4) for the purposes of field verification with NCDWQ. NCDWQ and GMI staff
conducted stream origin determinations in Project Area A on April 91h, 19th and July 6th, 2012.
All of the GMI identified USACE jurisdictional features (WoUS), which the USACE
Washington Field Office had verified on November 2 "d, 2011, and February 21St, and May 29th,
2012, were re- visited by NCDWQ and GMI. NCDWQ determined stream origins for the Neuse
River buffer subject features and verified the non - subject status of the additional USACE WoUS
features in Project Area A.
All subject stream origins and non - subject WoUS origins were NCPLS surveyed after
verification by NCDWQ and USACE. The NCPLS Origins Table provides origin
determinations of the Neuse River buffer subject and non - subject features in GMI Cherry Point
Project Area A for planning and permitting purposes and are valid for five years from the date of
NCDWQ signature.

direct supervision from an actual survey made under my direct supervision; that the regulated area is
located upon Federal land within MCAS Cherry Point; that the purpose of this coordinate sheet is to
delineate the origins of streams and does not conform to NCGS 47 -30; that stream origin flags are
