Noted deviations from approved plans and specification: Built -upon area for Pond 1 was increased by approximately 2310 SF due to the addition of an ATM within the parking lot on the Shops tract. This minimum increase in built -upon area does not adversely impact the Stormwater Management System because the actual surface area ratio for the Pond was greater than the required surface area ratio and this modification was absorbed within this overage.

High Density Developments with Outparcels Deed Restrictions & Protective Covenances In accordance with Title 15 NCAC 2H.1000, 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, Art Kepes 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 NumberSW6081103 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 The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5, Alteration of the drainage as shown on the approved plan may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 built -upon area for the outparcell's) shown on the approved plans is as follows. I 10. Outparcel it BUA Outparcel # BUA Outparcel BETA 1 85% 3 85% Excess Prop 81% 85% 4 72% These allotted aniounts include any built -upon area constructed within the property boundaries, and that portion of the right-of-way between the lot limes 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. The runoff from all built -upon area within the outparcel or future development area must be directed into the permitted stormwater control system. Built -upon area in excess of the permitted amount will require a permit modification. 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.

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.

This system (check one): ❑ does ® does not incorporate a vegetated filter at the outlet. This system (check one): ❑ does ® does not incorporate pretreatment other than a forebay. Important maintenance procedures: — 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 greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows.
