SW6170702 - Wynnridge Subdivision - Phase 3 (2)

Low Density Residential Subdivisions
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 Low Density Residential
Subdivisions where lots will be subdivided and sold. Deed restrictions and protective covenants are
necessary to ensure that the development maintains a "built -upon" area consistent with the applicable
regulation governing the density level.
I, James W. Johnson, III acknowledge and affirm by my signature below,
that I will cause the following deed restrictions and protective covenants to be recorded for Phase 3 -
Wynnridge Subdivision prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number , 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 The covenants pertaining to stormwater may not be altered or rescinded without the express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 13,412 square feet for lots 21-32 and
7,124 square feet for lots 15-20. 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, swales, 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 rojects located in the 20 coal al counties.

STORMWATER MANAGEMENT PERMIT APPLICATION FORM
LOW DENSITY SUPPLEMENT
This form may be photocopied for use as an original
A low density project is one that meets the appropriate criteria for built upon area and transports stormwater
runoff primarily through vegetated conveyances. 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).

H. BUILT UPON AREA
Refer to DEMLR's forms and applications website for specific language that must be recorded in the deed
restrictions for all subdivided projects. aZp://portal.ncdenr.org/web/lr/state-stortnwater-forms docs)
Complete the following calculation in the space provided below where:
• SA Site Area - the total project area above Mean High Water.
• DF Density Factor - the appropriate percent built upon area divided by 100.
• RA Road Area - the total impervious surface occupied by roadways.
• OA Other Area - the total area of impervious surfaces such as clubhouses, tennis courts, sidewalks, etc.
• No. of Lots - the total number of lots in the subdivision.
• BUA per Lot - the computed allowable built upon area for each lot including driveways and impervious
surfaces located between the front lot line and the edge of pavement.
• Total allowable lot BUA - the computed allowable built upon area for all lots combined.
Form SW401-Low Density-Rev.3-2/10/09 Page 1 of 5

• Total BUA from lot listing - the sum of built upon area allocated for each lot on the list of non-uniform lots.
Calculation:
For uniform lot sizes:
(SA: ft2 x DF: ) — (RA: ftZ) — (OA: ft) = BUA per Lot = ftz
(No of Lots: )
For non-uniform lot sizes:
a. (SA: 896,976 ft x DF: 0.24) — (RA: 14,825 ft2) — (OA: 0 ft2) = Total allowable lot BUA = 200,450 ft'

V. SWALE SYSTEM MAINTENANCE REQUIREMENTS
1. Mowing will be accomplished as needed according to the season. 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.
I acknowledge and agree by my signature below that I am responsible for the performance of the six
maintenance procedures listed above. I agree to notify DEMLR of any problems with the system or prior to any
changes to the system or responsible party.

PROJECT NARRATIVE
Phone: [phone]

Email: [e-mail]
Project Description
The purpose of this project is to develop a 20 lot residential subdivision. The subdivision site
is 20.59 acres and is located along Wynnridge Drive (off of Old Stage Road N - SR 1006) in
Grove Township, Harnett County, NC. All subdivision construction has been considered in
this land disturbance activity.
Site Description
The site is partially wooded and partially agriculture land. Existing topography drains from the
Northwest to the Southeast with slopes ranging from approximately 2% - 10% into an unnamed
tributary to Black River.
Adjacent Property
The land uses in the surrounding areas are residential and undeveloped.
Soils
The soils in the project area consist of Bb (Bibb loam, frequently flooded), NoC (Norfolk
loamy sand, 6 to 10 percent slopes), and FaB (Fuquay loamy sand, 0 to 6 percent slopes). Bb is
categorized as poorly drained, moderately permeable, and is poorly suited to urban and
recreational uses. NoC is categorized as well drained, moderately permeable, and is well suited
to most urban and recreational uses. FaB is categorized as well drained, moderately permeable,
and is moderately suited to most urban and recreational uses.
Planned Erosion and Sediment Control
As shown on the Erosion Control Plan the project will be controlled and stabilized with
diversion berms, silt fence, silt fence outlets, and temporary skimmer basins w/baffles. Topsoil
will be stored on site (temporary stockpile area) and berms will be constructed from topsoil
graded from the site and will be backed with silt fence. Skimmer basins will be constructed
with baffles and outlet protection. All measures will be constructed and maintained to NCDEQ
standards and requirements.
After erosion control measures are removed. Surface waters from the roadway areas will drain
via grassed roadside ditches to a grassy Swale (Lot 30/31) which will convey the runoff to an
undisturbed low area of the site. Impervious areas on the lots will surface drain through the
grassed yard areas over the natural contours of the Site.
