Dear Mr. Brydge:
The Washington Regional Office received a complete Stormwater Management Permit Application for
Grantham Crossing on April 03, 2006. Staff review of the plans and specifications has determined that
the project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC
2H.1000. We are forwarding Permit No. SW7060208 dated May 5, 2006, for the construction of the
subject project.
This permit shall be effective from the date of issuance until May 5, 2016, and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within sixty (60) days following receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina

STORMWATER MANAGEMENT NARRATIVE
GRANTHAM CROSSING
US HIGHWAY 70 EAST
NEW BERN, NC
This project proposes the development of a strip type commercial building between an existing
railroad and a US Highway 70 Service Road. The project is high density and proposes the use of
two separate bio-retention areas for stormwater management. The site is 2.64 acres in size and is
currently undeveloped with no existing impervious surface. There is no off -site area, pervious or
impervious, which discharges to the site. There are no Section 404, Coastal Wetlands or "blue
line" streams on the site.
The bio-retention area shown at the front or eastern side of the site will collect the runoff from all
of the impervious drive, parking and sidewalk areas at the front of the site. The building runoff
will all discharge to the rear or western side of the site. The bio-retention area is sized using 7%
of the impervious area. The one -inch storm runoff will result in a water level rise of 9.6 inches
before the off-line swale bypass system diverts the runoff exceeding the one -inch storm around
the bio-retention area.
The bio-retention area shown at the rear or western side of the site will collect the runoff from all
of the impervious drive, parking, walkway and building roof areas at the rear of the site. The bio-
retention area is sized using 7% of the impervious area. The one -inch storm runoff will result in a
water level rise of 10.2 inches before the off-line swale bypass system diverts the runoff exceeding
the one -inch storm around the bio-retention area.
The flow area into each of the two bio-retention areas incorporates a wide flow area to establish
sheet flow. This filter strip will be vegetated with centipede sod.
Planting and soil specifications for the two bio-retention areas are as shown on the plans. The
planting specifications include three species of trees and shrubs and a seed mixture of herbaceous
species.

Inspection Summary:
Inspection at Grantham Crossing located adjacent to US70 near intersection with Grantham Rd just East of New Bern.
This is a 2.6 ac business type development with a Pizza Hut, State Farm Insurance, & New Bern Family Denistry office.
The project appears to be complete & constructed according to plans.
Stormwater is routed to 1 of 2 Bioretention Basins. The drainage area of the front basin is about 1.5 acres & is well
vegetated with grass & some trees; O&M of this basin appears to be good. The basin located in the rear is somewhat
overgrown with woody vegetation; needs to be thinned/trimmed to allow more light penetration for grass vegetation to
survive. Minor erosion along slopes; some grading & reseeding needed; trash & debris needs to be removed. Signed
O&M agreements in on file; no PE Certification has been submitted. Need to check for ownership change.

Subject: Stormwater Permit No. SW7060208 Renewal
Grantham Crossing
High Density Stormwater Project
Craven County
Dear Robin Strickland:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7060208 for a stormwater treatment system consisting of two
bioretention basins serving a Grantham Crossing located at 2707 E US Hwy 70 in New
Bern, NC expires on May 5, 2020. This is a reminder that permit renewal applications
are due 180 days prior to expiration. We do not have a record of receiving a renewal
application.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal. Also, it was noted in the file review that a designer's certification that the
project was constructed in accordance with the approved plans as required by the
permit has not been submitted. Please include this with your application. Permit
application forms for renewal can be found on our website at:
https:.Udeg nc.gov/about4divisi ns jenerg.v-mineral-land-resources/energy-,mineral-land-
rules/stormwater-proogramJpot-construction. North Carolina General Statutes and the
Coastal Stormwater rules require that this property be covered under a stormwater
permit. Failure to maintain a permit subjects the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application forms. You can request a copy by e-mailing me at [e-mail].
