Deed restrictions and protective coven ppli necessary to ensure that the development maintains a "built -upon" area consistent with the a !M;!�Zj��� regulation governing the density level G I, Cameron Helms acknowledge and affirm by my signature below, that I will cause the following deed restrictions and protective covenants to be recorded for Canisteo Subdivision prior to the sale of any lot: 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number SW3170604 , 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 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 The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Energy, Mineral and Land Resources. 5.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 allowable built -upon area per lot is N/A (under 2 QUA) 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, and coquina, but does not include raised, open wood decking, or the water surface of swimming pools. 7. In the case of a lot within CAMA's regulated AEC, where the Division of Coastal Management calculates a different maximum allowable built -upon area for that lot than is shown herein, the governing maximum built -upon area for that lot shall be the most restrictive of the two. 8. Filling in or piping of any vegetative conveyances (ditches, swa/es, etc.) associated with the development except for average driveway crossings is strictly prohibited by any persons. 9. Each lot will maintain a 30* foot wide vegetated buffer between all impervious areas and surface waters. 10. All roof drains shall terminate at least 30* foot from the mean high water mark of surface waters. *50 foot for pr fects located in the 1200 coastal counties.

Low density projects should not have a discrete stormwater collection system as defined by 15A NCAC 2H .1002(18). Low density requirements and density factors can be found in Session Law 2008-211, 15A NCAC 2H.1000, Session Law 2006-246 and the State of North Carolina Stormwater Best Management Practice Manual. Curb and gutter systems are allowed provided they meet the requirements in 15A NCAC 2H .1008(g). I.

Grass height will not exceed six inches at any time; and grass will not be mowed too close to the ground or "scalped". 2. Swales will be inspected monthly or after every runoff producing rainfall event for sediment build-up, erosion, and trash accumulation. 3. Accumulated sediment and trash will be removed as necessary. Swales will be reseeded or sodded following sediment removal. 4. Eroded areas of the swales will be repaired and reseeded. Swales will be revegetated as needed and in a timely manner based on the monthly inspections. Side slopes must be maintained at the permitted slope. 5. Catch basins, curb cuts, velocity reduction devices, and piping will be inspected monthly or after every significant runoff producing rainfall event. Trash and debris will be cleared away from grates, curb cuts, velocity reduction devices and piping. 6. Swales will not be altered, piped, or filled in without approval from NCDENR Division of Energy, Mineral and Land Resources.
