Dee Freeman
Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for Lee
Professional Park on December 2, 2009. Staff review of the plans and specifications has determined that the
project, as propo:;-!d, will comply with the Stormwater Regulations set forth in Title 15A NCAC 21-1.1000 and
Session Law 2006-246. We are forwarding Permit No. SW6091003, dated December 9, 2009, for the construction,
operation ::nd maintenance of the subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until December 9, 2019, 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 inspection 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 150B 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.
This project will be kept on file at the Fayetteville Regional Office. If you have any questions, or need additional
information concerning this matter, please contact Cory Larsen at [phone]; or [e-mail].
Sincerely,

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BIv1P. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements rioted 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 operation and maintenance procedures:
Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
Heavy equipment will NEVER be driven over the bioretention cell.
Special care will be taken to prevent sediment from entering the bioretention cell.
Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month 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.

High Density Commercial Subdivisions
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 2H.1000, the Management Regulations, deed restrictions and
protective covenants are required for High Density Commercial Subdivisions where lots will be
subdivided and sold and runoff will be treated in an engineered stormwater control facility. Deed
restrictions and protective covenants are necessary to ensure that the development maintains a built -
upon area consistent with the design criteria used to size the stormwater control facility.
I, Jay lee kl�lcs , acknowledge, affirm and agree by my signature below, that
I will cause the following deed restrictions and covenants to be recorded prior to the sale of any lot
within the project known as 1-e-F ?rz-6f —Ssr dnik'L {4v2--tc
3.
4.
5.
6.
The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number _ Stifb oil ^03 as issued by the Division of Water Quality
under NCA C 2H.1000.
The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
These covenants are to run with the land and be binding on all persons and parties claiming
under them.
The covenants pertaining to stormwater may not be altered or rescinded without the express
written consent of the State of North Carolina, Division of Water Quality.
Alteration of the drainage as shown on the approved plan may not take place without the
concurrence of the Division of Water Quality.
The maximum allowable built -upon area per lot is square feet. {OR, if the
proposed built -upon area per lot will vary, please use the following format & language (in bold):
The maximum built -upon area per lot, in square feet, is as Hsted*91Gw. (�-_ �
Lot # BUA Lot # BUA Lot # BUA Lot # BUA
This allotted amount includes any built -upon area constructed within the lot property boundaries,
and that portion of the right-of-way between the front lot line and the edge of the pavement. Built
upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate,
coquina and parking areas, but does not include raised, open wood decking, or the water
surface of swimming pools.
All runoff from the built -upon areas on the lot must drain into the permitted system. This may be
accomplished through a variety of means including roof drain gutters which drain to the street,
grading the lot to drain toward the street, or grading perimeter swales to collect the lot runoff
and directing them into a component of the stormwater collection system. Lots that will naturally
drain into the system are not required to provide these additional measures.
The owner of each lot, whose ownership is not retained by the permittee, is required to submit a
separate stormwater permit application to the Division of Water Quality and receive a permit
prior to construction.
