Subject: Approved Plan Revision
Morehead City Police Department— Renovations and Additions
Stormwater Project No. SW8 081025
Carteret County
Dear Mr. Martin:
On October 26, 2009, the Wilmington Regional Office received a plan revision for Stormwater
Management Permit Number SW8 081025. The revisions include shifting the proposed structure 15'
off of the property line and compressing the parking area behind said structure. This will cause a net
decrease of 11,710 square feet in the original built-upon-area (BUA) that will be retained as future
BUA. It has been determined that a formal permit modification is not required for the proposed
chances. We are forwarding you an approved copy of the revised plans for your files. Please replace
the old approved plan sheets (full set) with the new ones.
Please be aware that all terms and conditions of the permit issued on April 1, 2009, remain in full
force and effect. Please also understand that the approval of this revision to the approved plans
for the subject State Stormwater Permit is done on a case-by-case basis. Any other changes to
this project must be submitted to and approved through the Division of Water Quality prior to
construction. The issuance of this plan revision does not preclude the permittee from complying
with all other applicable statutes, rules, regulations or ordinances which may have jurisdiction over
the proposed activity, and obtaining a permit or approval prior to construction.
If you have any questions concerning this matter, please do not hesitate to call me at [phone].
Sincerely,
C-

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.

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:
- Immediately after the filter strip is established,any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
- Once a year,the filter strip will be reseeded to maintain a dense growth of
vegetation
- Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
- Two to three times a year,grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency.Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
- Once a year,the soil will be aerated if necessary.
- Once a year,soil pH will be tested and lime will be added if necessary.
After the filter strip is established,it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (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.

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, R. Randy Martin, City Manager , 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 Renovations and Additions to: Morehead City Police Department
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number.�d,BQ8/401.S , as issued by the Division of Water Quality
under NCAC 2H.1000.
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming
under them.
4. 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.
5. Alteration of the drainage as shown on the approved plan may not take place without the
concurrence of the Division of Water Quality.
6. The maximum allowable built-upon area per lot is 127,229 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 listed below:
