Subject: Stormwater Permit No. SW7070715 Modification
Lighthouse Assembly of God Church of Buxton
High Density Project
Dare County
Dee Freeman
Secretary
The Washington Regional Office received a complete Stormwater Management Permit Application for the
modification of Lighthouse Assembly of God, Church of Buxton on December 17, 2008. 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. SW7070715MOD dated
February 23, 2009, for the construction of the subject project. The stormwater permit issued for this project on
August 3, 2007 is hereby rescinded and is replaced by this permit.
This permit shall be effective from the date of issuance until August 3, 2017, 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 thirty (30) days following receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter 150E of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 27611-
7447. Unless such demands are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please contact Scott Vinson,
or me at (252) 946-6481.

I. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
This stormwater system has been approved for the management of stormwater
runoff as described in Section 1.6 on page 3 of this permit. The stormwater control
has been designed to handle the runoff from 38,971 square feet of impervious
area.
The tract will be limited to the amount of built -upon area indicated on page 3 of this
permit, and per approved plans.
All stormwater collection and treatment systems must be located in either dedicated
common areas or recorded easements. The final plats for the project will be
recorded showing all such required easements, in accordance with the approved
plans.
5. The runoff from all built -upon area within the permitted drainage area of this project
must be directed into the permitted stormwater control system.

Infiltration Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
