High Density Develoaments with Outparcels
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 2H.1000 and S.L. 2006-246, the Stormwater Management
Regulations, deed restrictions and protective covenants are required for High Density Developments
with Outparcels where outparcel lots will be subdivided from the main tract and sold. 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, Will Tirmins , 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
outparcel or future development area:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number SW8 160501 , as issued by the Division of Energy, Mineral
and Land Resources under the Stormwater Management Regulations.
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 ran 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 The covenants pertaining to stormwater may not be altered or rescinded without the express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 Energy, Mineral and Land Resources.
5. Alteration of the drainage as shown on the approved plan may not take place without the
concurrence of the Division of Energy, Mineral and Land Resources.
6. The maximum built -upon area for the outparcel(s) shown on the approved plans is as follows:
Oulparcel # BUA Outparcel # BUA
1319-79 38,685 SF
These allotted amounts include any built -upon area constructed within the property boundaries,
and that portion of the right-of-way between the lot lines 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.
7. The runoff from all built -upon area within the outparcel or future development area must be
directed into the permitted stormwater control system.
8. Built -upon area in excess of the permitted amount will require a permit modification.
9. The connection from the outparcel(s collection system into the stormwater control shall be made
such that short-circuiting of the system does not occur.
10. For those outparcels or future development areas whose ownership is not retained by the
permittee, the new owner shall submit a separate offsite stormwater permit application to the
Division of Energy, Mineral and Land Resources and receive a permit prior to construction.
11. The project and each outparcel will maintain a 30** foot wide vegetated buffer between all
impervious areas and surface waters.
**50 foot for projects located in the 20 coastal counties. ECEIVE

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 shall 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 shall be kept in a known set

important mamtenance proceaures:
Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the
basin should be watered twice weekly if needed, until the plants become established (commonly six weeks).
No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to
establish the plants on the vegetated shelf.
Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention
basin.
If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the
emergency drain should be minimized to the maximum extent practical.
- Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event
