Subject: State Stormwater Management Permit No. SW8 120902
The Sanctuary of Wilmington
High Density Commercial Infiltration System
New Hanover County
Dear Mr. Cook:
The Wilmington Regional Office received a complete State Stormwater Management Permit
Application for The Sanctuary of Wilmington on October 1, 2012. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater
Regulations set forth in Session Law 2008-211 and Title 15A NCAC 2H.1000. We are
forwarding Permit No. SW8 120902 dated October 9, 2012, for the construction, operation, and
maintenance of the BMP's and built -upon area associated with the subject project.
This permit shall be effective from the date of issuance until October 9, 2020, and shall be
subject to the conditions and limitations as specified therein. Please pay special attention to the
conditions listed in this permit regarding the Operation and Maintenance of the BMP(s),
recordation of deed restrictions, certification of the BMP's, procedures for changes of
ownership, transferring the permit, and renewing the permit. Failure to establish an adequate
system for operation and maintenance of the stormwater management system, to record deed
restrictions, to certify the BMP's, to transfer the permit, or to renew the permit, 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 by filing a written petition with the Office of
Administrative Hearings (OAH). The written petition must conform to Chapter 150B of the North
Carolina General Statutes, and must be filed with the OAH within thirty (30).days of receipt of
this permit. You should contact the OAH with all questions regarding the filing fee (if a filing fee

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
Chris Baker, at [phone].

on page 3 of this permit, and as shown on the approved plans.
4. 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.
6. The project shall provide a 50' wide vegetated buffer adjacent surface waters,
measured horizontally from and perpendicular to the normal pool of impounded
structures, the top of bank of streams and rivers, and the mean high water line of
tidal waters:

VII. DEED RESTRICTIONS AND PROTECTIVE COVENANTS
For all subdivisions, outparcels, and future development, the appropriate property restrictions and protective
covenants are required to be recorded prior to the sale of any lot. If lot sizes vary significantly or the proposed
BUA allocations vary, a table listing each lot number,'lot size, and the allowable built -upon area must be
provided as an attachment to the completed and notarized deed restriction form. The appropriate deed
restrictions and protective covenants forms can be downloaded from
htlp://portal.ncdenr.org/web/wq/ws/su/st,itesw/forms_docs..Download the latest versions for each
submittal.
In the instances where the applicant is different than the property owner, it is the responsibility of the property
owner to sign the deed restrictions and protective covenants form while the applicant is responsible for ensuring
that the deed restrictions are recorded.
By the notarized signature(s) below, the permit holder(s) certify that the recorded property restrictions and
protective covenants for this project, if required, shall include all the items required in the permit and listed
on the forms available on the website, that the covenants will be binding on all parties and persons claiming
under them, that they will run with the land, that the required covenants cannot be changed or deleted
without concurrence from the NC DWQ, and that they will be recorded prior to the sale of any lot.

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 of the infiltration trench will be carefully managed to reduce
the sediment load to the sand filter.
— The water level in the monitoring wells will be recorded once a month and after
every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
The infiltration trench 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.

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 Iocation. 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.
