Dear Ms. Beaman:
The Wilmington Regional Office received a complete,modified State Stormwater Management
Permit Application for Oyster Landing Subdivision on December 7,2015 with revised plans
received on February 15,2016. Staff review of the plans and specifications has determined that
the project, as proposed,will comply with the Stormwater Regulations set forth in Title 15A
NCAC 2H.1000 and Session Law 2008-211. We are forwarding modified Permit No. SW8
070653 dated March 2,2016, for the construction, operation and maintenance of the BMP's and
built-upon area associated with the subject project.
This permit shall be effective from the date of issuance until March 2,2024, and shall be subject
to the conditions and limitations as specified therein. Please pay special attention to the
conditions listed in this permit regarding the Operation and Maintenance of the BMP(s),
recordation of deed restrictions, certification of the BMP's,procedures for changing ownership,
transferring the permit, and renewing the permit. Failure to establish an adequate system for
operation and maintenance of the stormwater management system,to record deed restrictions,to
certify the BMP's,to transfer the permit, or to renew the permit,will result in future compliance
problems.

The onsite buildings impervious area for DA 1 is for 64 previous lots and one lot in Phase II so the total of 260,390 sf

Mark,
The previous permit calls for 474 lots at 4,006 square feet each. This amounts to a sum total of 1,898,844
square feet or 43.59 acres of BUA. Is this still correct for the overall BUA? Your calculations show only
386,579 square feet for Lot BUA. I assume that's what is currently constructed? Also, the future BUA was
listed as 2,871,466 square feet.
So,to summarize, I need the following breakdown of proposed BUA:
Lots,ft2:

Sidewalks, paths,etc., ft2:
Future, ft2:
Please include all proposed BUA at the current time. The Future amount can be a lump sum category.

I am reviewing your project for Oyster Landing. It appears that you have added a large portion to drainage
area 2 and added drainage area 3, but have reduced drainage area 1 slightly. Can you provide further

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. 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.

pretreatment including forebays and the vegetated filter if one is provided.
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
location and must be available upon request. ';"fib

STORM WATER NARRATIVE
OYSTER LANDING PHASE II
SNEADS FERRY, NC
December, 2015
The site is located on NC 172 approximately 1.5 miles east of US HWY 17. This project
was previously permitted as a low density project on October 2, 2007 (SW8 070653). The
original project was designed as a low density subdivision with roadside swales. The
original owners had to declare bankruptcy and the current owner of the property that had
not been developed has decided to modify the plans for the rest of the property. The roads
will now have curb and gutter and storm water will be conveyed to a wet detention basin
by culverts. The project will remain a "Low Density" project and the allowable BUA per
lot will remain at 4,006 sf.
The site drains to Stones Creek (SA; HQW) and Turkey Creek (SA; ORW). The project for
this submittal will have three (3) drainage basins. The first two are the two areas that drain
to Stones Creek (Drainage Area No. 1) and Turkey Creek(Drainage Area No. 2). Drainage
Basin No. 3 is the area that will drain to the new proposed wet pond. The impervious area
shown for this drainage area is also included in the impervious area for Drainage Area No.
2. The drainage area line between Stones Creek and Turkey Creek have changed from the
original permitted plans due to the future roads having curb & gutter. The drainage
boundary line was revised to reflect what would drain to the roads that would convey
storm water runoff to a wet pond and/or swale running down a lot line.
For Drainage Area No. 1,the amount of existing impervious area that has been constructed
was determined based on the roads that have been constructed and lots that have been
developed. Future impervious area is provided in the permit to allow for undeveloped
area to be constructed that lies within the drainage boundary.
Drainage Area No. 2 includes the area shown for Drainage Area No. 3. The impervious
area proposed for the next phase of construction is shown in both Drainage Areas No. 2 &
3. Future impervious area is provided in the permit for Drainage Area No. 3 to allow for
the rest of the area to be constructed. The pond for this phase of the project is located
outside the ' mile line of Turkey Creek and is located in Drainage Area No. 3.
The subdivision is 319 acres and the allowable impervious area remains at 24.4% which
equates to 3,390,536 sf of impervious area. y, ,,

Reference: Report of Seasonal High Water Table Estimation
Oyster Landing Phase 2
Stump Sound, Onslow County, North Carolina
ECS Project No. 49.1423
Dear Mr. Carlisle:
ECS Carolinas, LLP (ECS) recently conducted an estimation of the Seasonal High
Water Table (SHWT) for the proposed stormwater best management practice (BMP)
areas at the Oyster Landing Phase 2 site in Stump Sound, Onslow County, North
Carolina. This letter, with attachments, is the report of our estimation.
Field Testing
On February 9, 2016, ECS conducted an exploration of the subsurface soil and SHWT
conditions at one requested location shown on the attached Boring Location Plan
(Figure 1). The purpose of this exploration was to estimate the SHWT of the in place
soils for the design of for the proposed stormwater BMP area. The boring was located
by using a site plan provided by Port City Consulting Engineers, PLLC. ECS explored
the subsurface soil and groundwater conditions by advancing one hand auger boring
into the existing ground surface at the requested boring location. ECS visually
classified the subsurface soils and obtained representative samples of each soil type
encountered. ECS recorded the SHWT and groundwater elevation observed at the time
of the hand auger boring. The attached SHWT sheet provides a summary of the
subsurface conditions encountered at the hand auger boring location.
The SHWT and groundwater elevation were estimated at the boring location below the
existing grade elevation. Below is a summary of each boring location.
Location SHWT Groundwater
B-1 22 inches 30 inches
The SHWT may vary within the proposed site due to changes in subsurface conditions
and elevation.

Dear Mr. Hargrove:
The following is a summary of the soil profiles taken at the Oyster Landing S/D located on Hwy
172 in Sneads Ferry, NC. The purpose of the evaluation was to determine the estimated
Seasonal High Water Table (SHWT)and to determine the infiltration rate of the soil. A hand
auger was used to obtain the soil profiles and to determine the SHWT. Field techniques outlined
in the North Carolina Laws and Rules for Sewage Treatment and Disposal Systems were used to
determine soil texture, structure,consistency and soil wetness condition.

SHWT was'determined by the indication of colors of chroma 2 or less*Hiving a Munsell Soil
color Chart at>2%of soil volume in mottles or matrix of a horizon or horizon subdivision. The
actual SHWT is controlled on the site by a perimeter drainage ditch that is approximately 2-3'in
depth. This ditch runs the property line and was functioning at the time of my evaluation.
The SHWT on the site has been altered by the presence of a ditch along the property line
adjacent to the proposed storm water pond. The ditch was found to be approximately 4'
in depth and has a significant lateral effect on the site
If you have any questions,please feel faee_to contact me at(910)330-2784. Thank you.

STORM WATER NARRATIVE
OYSTER LANDING PHASE II
SNEADS FERRY, NC
December, 2015
The site is located on NC 172 approximately 1.5 miles east of US HWY 17. This project
was previously permitted as a low density project on October 2, 2007 (SW8 070653). The
original project was designed as a low density subdivision with roadside swales. She,
on final owners had to declare bankrupt r of the property that i�d �,,�° 1
not been develo has decided to modi the plans for the rest of the property. The roads �I'�" r*4)
wi now have curb and gutter and storm water will be conveyed to a wet detention basin VT
by culverts. The project will remain a "Low Density" project and the allowable BUA per
lot will remain at 4,006 sf.
The site drains to Stones Creek (SA; HQW) and Turkey Creek (SA; ORW). The project for
this submittal will have three (3)drainage basins. The first two are the two areas that drain
to Stones Creek(Drainage Area No. 1) and Turkey Creek (Drainage Area No. 2). Drainage
Basin No. 3 is the area that will drain to the new proposed wet pond. The impervious area
shown for this drainage area is also included in the im ervious rea for Drainer Area No.
2. The drainage area line between Stones Creek an Turkey Creek have changed from the
original permitted plans due to the future roads having curb & gutter. The drainage
boundary line was revised to reflect what would drain to the roads that would convey
storm water runoff to a wet pond and/or swale running down a lot line.
For Drainage Area No. 1,the amount of existing impervious area that has been constructed
was determined based on the roads that have been constructed and lots that have been
developed. Future impervious area is provided in the permit to allow for undeveloped
area to be constructed that lies within the drainage boundary.
Drainage Area No. 2 includes the area shown for Drainage Area No. 3. The impervious
area proposed for the next phase of construction is shown in both Drainage Areas No. 2 &
3. Future impervious area is provided in the permit for Drainage Area No. 3 to allow for
the rest of the area to be constructed. The pond for this phase of the project is located
outside the1 mile line of Turkey Creek and is located in Drainage Area No. 3.
The subdivision is 319 acres and the allowable impervious area remains at 24.4% which
equates to 3,390,536 sf of impervious area.

Paved Areas = 132,491 sf
Lot BUA = 386,579 sf
Future Impervious Area = 2,871,466 sf
3,390,536 sf — 77.84 ac
77.84/319 = 24.4%
The site meets the low density criteria for subdivisions.
