New Hanover County
Dear Mr. Everett:
On December 1, 2004, personnel of this office inspected a project located on NC 132 (South College
Road) in New Hanover County, North Carolina. This inspection was performed to determine compliance with
the North Carolina Sedimentation Pollution Control Act of 1973. The inspection revealed a land -disturbing
activity of approximately 9.02 acres being conducted.
It is our understanding that you and/or your firm are responsible for this land -disturbing activity. The
purpose of this letter is to inform you that this activity was found to be in violation of the Act, NCGS 11 3A-50
to 66, and Title 15A, North Carolina Administrative Code, Chapter 4. If you feel that you are not responsible
for the following violations, please notify this office immediately.
The violations that were found are:
1 . Failure on a tract of more than one acre, when more than one acre is uncovered, to provide a
permanent ground cover sufficient to restrain erosion on such exposed areas within 30 working
days or 90 calendar days, whichever is the shorter after completion of construction or
development. G.S. 1 13A-57(3) and 1 5A NCAC 4B.0107(b) and 15A NCAC 4B.01241e).
Ditches are bare along western and southern edges.
2. Failure on a tract of more than one acre, when more than one acre is uncovered, to install
sedimentation and erosion control devices sufficient to retain the sediment generated by the
land -disturbing activity within the boundaries of the tract during construction upon and
development of the tract. G.S. 113A-57;3j.
Drop inlets are unprotected and sediment is running off -site.
3. Failure to take all reasonable measures to protect all public and private property from damage
by such land -disturbing activities. 1 5A NCAC 4B.0005.
Sediment is leaving the site.
4. Failure within 15 working days of 30 calendar days (whichever period is shorter) of completion
of any phase of grading to plant or otherwise provide exposed, graded slopes or fills with
ground cover, devices, or structures sufficient to restrain erosion. G.S. 113A-57(2).
There are bare and eroding slopes around pond in northwest corner.

5. Failure to maintain satisfactorily all temporary and permanent erosion and sedimentation control
measures and facilities during the development of a site. 15 NCAC 413.013.
Erosion control measures are non-existent around drop inlets.
To correct these violations, you must:
A. Re -seed and mulch drainage ditches: south property edge, southwest corner to along western
edge, and beside storm water pond along southern edge between Phase 1 and Phase 2.
B. Install drop inlet protection devices around drop inlet located along southern edge of Phase 2.
C. Re -grade Ito remove erosion gullies), re -seed, and mulch slopes around sediment pond in
northwest corner of site.
Please note that merely planting grass seed does not satisfy the requirements of "vegetative cover"
or of "ground cover sufficient to restrain erosion." These requirements are not satisfied until a standing cover
of grass or other ground cover is established which is, in fact, sufficient to restrain accelerated or man-made
erosion.
The initial one day civil penalty could be an assessment of up to $5,000.00. A time period for
compliance is not required for this initial one day civil penalty pursuant to NCGS 113A-61 .1 (c) and NCGS
113A-64(a)(1). An initial one day civil penalty is being considered for this project.
If the violations described in this Notice are not corrected within 28 days following your receipt
of this Notice, the Division of Land Resources may take additional appropriate legal action against you pursuant
to NCGS 113A-64. That action could be the assessment of additional civil penalties and may result in the
initiation of other remedies as prescribed by the Act. If additional civil penalties are assessed for the violations,
the amount may be up to $5,000.00 per day for each day of the violation pursuant to NCGS 1 33A-64(a)(1).
If all violations are corrected within the time period specified for compliance, additional civil penalties or legal
remedies will not be pursued.
Any new land -disturbing activity associated with this project should not begin until the area presently
disturbed is brought into compliance with the Act. When corrective actions are complete, you should notify
this office so that the work can be inspected. You should not assume that the site is in compliance with the
Act until we have so notified you. In addition, once compliance has been achieved, all installed measures must
be satisfactorily maintained until development is complete and the site is fully stabilized to avoid further
violations of the Act.
We solicit your cooperation, and would like to avoid taking further enforcement action. At the same
time, it is your responsibility to understand and comply with the requirements of the Act. Copies of the
relevant statute and administrative rules may be examined at this office or will be sent to you upon request.
Should you have questions concerning this Notice or the requirements of the Act, please contact either
Schuyler Snowdon or me at your earliest convenience.
Please do not hesitate to contact me regarding any questions you might have about this matter.
Sincerely,

Y N
❑ ❑ The drainage area (including offsite) and built -upon area to the permitted
system are per the approved plan. No unpermitted offsite drainage enters
the system.
❑ ❑ All the built -upon area associated with the project is graded such that the
runoff drains to the system.
❑ ❑ For pond shnfiltration, the outlet/bypass structure relative elevations are
per the approved plan. (Must be verified via as -built survey if in question).
❑ ❑ The inlets and outlet structure are located per the approved plans and do
not cause short-circuiting.
❑ ® A trash rack is provided over the outlet weir and orifice.
❑ X All slopes are grassed with permanent vegetation and are not eroding.
❑ ❑ Vegetated slopes are no steeper than 3:1.
❑ ❑ The approximate amount of permitted surface area has been provided.
(Must be verified via as -built survey or designer's certification.)
❑ ❑ Required drawdown devices are correctly sized per the approved plans.
All required design depths are provided.
❑ ❑ All required parts of the system are provided, such as a vegetated shelf,
and a forebay.
❑ ❑ The designer's certification has been submitted.
❑ ❑ The required deed restrictions are correctly recorded and submitted.
❑ ❑ The number of lots or outparcels is per the permitted amount.
❑ ❑ The built -upon area on the lots or outparcels does not appear to exceed
the maximum amount (must be verified via as -built survey if in question)
❑ ❑ Curb outlet swales are constructed, located properly, are 100' long and
have dense vegetated cover.
❑ ❑ The road, cul-de-sac, parking lot and sidewalk widths are per the
approved plan.
❑ X Required maintenance is being performed.
❑ ❑ Outparcels have their own offsite permit.
❑ ❑ For low density projects, roadside swales are 3:1, vegetated and stable.
❑ ❑ For low density projects, there are no unpermitted pipes on the project.

4. Required Actions: (Explain each deficiency and what needs to be done to bring
the system back into compliance)
(a) A trash rack needs to be installed above the outlet structure ASAP.
(b) The large drainage Swale on site is badly eroded. The sides need to be
stabilized with grass or sod.
(c) There is an abundant amount of construction generated trash within and
around the pond. The trash is not only an eyesore it can also clog the outlet
structure and hamper the efficiency of the pond.
(d) The sides of the pond are badly eroded and need to be stabilized with
grasstsod or mulch.
(e) There is a large pile of sediment that is running off into the pond. The pile
which is located behind the dumpster needs to be removed. Due to the
abundance of impervious surface on the site, the pond should be fully
functional as a Stormwater Detention Pond.

NARRATIVE
Project Descr•ipt1011
The purpose of the proposed development is to allow Cor the proposed multi -family
development. Approximately 8.48 ,icres will be disturbed during the construction period. The site
is 9.02 acres located ill the Masonboro"I'ownship of New Hanover County, 1 mile north of the
Monkey Junction intersection oil NC 1 ;2.
Site Dcuri tion
The site has flat topography in the areas not previously clisturbccl. Soil stock pile are located
at the north, south, and western boundaries of the property. There is a small drainage ditch which
traverses the property with its invert at the western border of the property. Waters from the site drain
to Mott Creep, stream class CSW. Stormwater from the site will be collected in one OF drop
inlets and (9) curb inlets. Waters will be conveyed'to the proposecl'detention pond for treatment and
rclease at rates not to exceed pre -development rates.
Adiacent Properties
Land use in the vicinity is zoned residential and multifamily. The land immediately to the
south rind west is single-family homes. The area to the east is developed multifamily homes. Areas
to the north arc presently irnclevelolSecl.
Sails
The soil, as formed in the SCS Soil Survey ofNew Hanover County, is Leon, Lynn Haven and
Mrtrville. The majority of the property is considered to be poorly drained with permeability rates
less than 6 inches/hour at the surface and less than 2 inches/hour in the subsoil. The soil erodibility
Factor (K Factor) ranges from 0.1 to 02 for the depths to be excavated.
