APPLICANT'S CERTIFICATION 1, (print or type name of person listed in General Information, item 2) Tom Hicks certify that the information included on this permit application form is, to the best of my knowledge, correct and that the project will be constructed in conformance with the approved plans, that the required deed restrictions and protective covenants will be recorded, and that the proposed project complies with the requirements of 15A NCAC 2H .l Signature: Date: Form SWU-101 Version 8.07 Pace 4 of 4 High Density Residential Subdivisions 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 Residential 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, (-'> M tC S 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: 9. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number 'SW IDS-014 Mo r0 , 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 The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5.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. V4__ Jr. tL 6. The maximum allowable built -upon area per lot is 5 square feet. 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. OR, if the proposed built -upon areas per lot will vary, please REPLACE #6 above with the following: 6. The maximum built -upon area per lot, in square feet, is as listed below: 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. 7. 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 require hese dit al measures.

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).
