Camden, NC
Dear Mr. Vinson:
Please find enclosed two(2)copies of Sheet E2,revised April 21,2008,for the River Bridge
Apartment project.
The purpose of this revision is to change the pour-in-place flume type weir to a precast '
stepped, notched weir. There will not be any changes made to the pond dimensions or pond
elevations. The orifice will remain the same, as will the outflow channel with the Ievt:; spreader.
Calculations for the first ,tep of the proposed notched weir shows that it will exceed the quantity
of flow entering the pond.
Please call if you require any additional data or information.
Sincerely,

Wet Detention Basin Inspection 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.

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 inspection and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Dear Mr. Gregory:
This office received a Coastal Stormwater permit application and plans for the subject project on
September 7, 2007 with additional information received on January 14, 2008. A preliminary review of the project
indicates that before a State Stormwater permit can be issued the following additional information is needed.
1. Please provide the missing Sections I & II of the Wet Detention Basin Supplement form SW401. Section
III, Required Items Checklist on the second Excel tab was filled out and submitted, but the first tab
including Section I, Project Information & Sec.11, Design Information, was not.
2. Please revise page 2 of the application form to include one drainage area Column under Section III for the
Total Project site and a second column for the drainage area to the Wet Pond.
The above requested information must be received in this office prior to February 20, 2008 or your
application will be returned as incomplete. The return of this project will necessitate resubmittal of all required
items including the application fee. If you need additional time to submit the required information, please mail
or fax your request for time extension to this office at the Letterhead address.
You should also be aware that the Stormwater Rules require that the permit be issued prior to any
development activity. Construction without a permit is a violation of 15A NCAC 21-1.1000 and North Carolina
General Statute 143-215.1 and may result in civil penalties of up to$10,000 per day.
Please reference the Stormwater Project Number above on all correspondence. If you have questions,please

Project Narrative
River Bridge Apartments
Blue Sky Development, LLC
Existing Site Description:
The project site is located on the west side of NC Hwy. 158
approximately 0 . 25 mi . south of the NC Hwy. 343 intersection
at Camden. The existing improvements consist of four apartment
buildings and associated paved parking located on approx-
imately 11 acres of a 38 acre tract . The current method of
sewage treatment is by private ground absorption system.
Drainage to the west of the existing buildings sheet flows
to the adjacent swampland. Minor swales direct water away
from the sewer drain fields . Drainage to the east sheet flows
across the paved parking area to grass swales . There is no
offsite drainage across this property. The overall soil type
is State (fine sandy loam) and the receiving stream is Sawyers
Creek (class C SW) .
Proposed Improvements :
The proposed improvements consist of adding two 12-unit and
two 18-unit apartment buildings along with the required
parking areas . A new gravity sanitary sewer main will also be
installed to service both the new and existing buildings .
This gravity sewer main will feed a sewer pump station
operated by the County of Camden.
Temporary erosion control measures include placement of
stone construction entrances, rip-rap filter dams, and silt
fencing around disturbed areas as per plans . All disturbed
areas are to be seeded and mulched per erosion control
measures outlined on plans . Runoff will be transported by
vegetated swales constructed with 5 : 1 side slopes . The
exterior swale along the north property line will have a 3 : 1
outside slope with a 5 : 1 inside slope . All swales are `V'
shaped with a 0 . 3% drainage slope and less than 2 fps flow.

Due to a determination of pockets of high density within the
project area, a wet detention pond has been added to treat
runoff. Previously untreated runoff from 85% of the existing
impervious area will also be channeled to the wet detention
pond. The remaining 15%, consisting of rooftops and concrete
pads will continue to sheet flow across the grassed lawn. The
temporary pool will discharge over 2 . 3 days through a 1 . 5"
orifice . The 10' shelf will be vegetated with approved
wetland species along with the 10 . 5 foot outfall channel
leading to the level spreader .

Subject: Stormwater Review SW7000310 Modification
River Bridge Apartments
Camden County
Dear Mr.Gregory:
This office received a Coastal Stormwater permit application and plans for the subject project on
September 7, 2007. A preliminary review of the project indicates that before a State Stormwater permit can be
issued the following additional information is needed.
1. Please have the wetlands located around the project area properly delineated by a professionally trained
individual. The wetlands do not have to have an Army Corp of Engineers sign off, but they do need to be
properly delineated. Any portion of wetlands that boarder the project area should be properly delineated.
2. Please seal, sign and date two copies of the plans by either a professional surveyor or engineer.
3. Please provide a plan sheet that delineates the entire 38 acre tract of land, on a smaller scale 100' or 200' as
needed, and show the project area within the tract of land.
4. Please verify, and note on plans,that the delineated "Project Limits" is the entire 10.94 acre project within
the 38.6 ac tract of property. If it is not, please clearly delineate the entire project area.
5. After reviewing the proposed site layout, the configuration of the new impervious area constitutes a pocket
of high density. Please provide an engineered treatment system to collect and treat the runoff from the
buildings,parking and drives.
6. On the drainage basin schematic please add the amount of impervious area that correlates to each of the
basin areas that are listed. This helps in making the pocket of high density determination.
7. Please provide multiple swale cross sectional details, including labeled side slopes, for each type of swale
proposed. (6:1 slopes both sides, 3:1 outside slope& 5:1 inside slope, etc.)
8. Please provide the appropriate initials for section VI. SUBMITTAL REQUIREMENTS found on page 4 of
4 of the application. Page 4 is included with this letter for signature.
9. Please revise the narrative to explain in detail how stormwater runoff will be treated.
10. Please remember to seal, sign& date 2 copies of any revised plan sheets and calculations.

Project Narrative RECEIVED
River Bridge Apartments SEP 7 PTO/
Blue Sky Development, LLC
DWQ-WARD
Existing Site Description:
The project site is located on the west side of NC Hwy. 158
approximately 0 . 25 mi . south of the NC Hwy. 343 intersection
at Camden. The existing improvements consist of four apartment
buildings and associated paved parking located on approx-
imately 11 acres of a 38 acre tract . The current method of
sewage treatment is by private ground absorption system.
Drainage to the west of the existing buildings sheet flows
to the adjacent swampland. Minor swales direct water away
from the sewer drain fields . Drainage to the east sheet flows
across the paved parking area to grass swales . There is no
offsite drainage across this property. The overall soil type
is State (fine sandy loam) and the receiving stream is Sawyers
Creek (class C SW) .
Proposed Improvements:
The proposed improvements consist of adding two 12-unit and
two 18-unit apartment buildings along with the required
parking areas . A new gravity sanitary sewer main will also be
installed to service both the new and existing buildings .
This gravity sewer main will feed a sewer pump station
operated by the County of Camden.
Temporary erosion control measures include placement of
stone construction entrances, rip-rap filter dams, and silt
fencing around disturbed areas as per plans . Permanent
measures include rip-rap dissipaters placed at newly
constructed swale outfalls. All disturbed areas are to be
seeded and mulched per erosion control measures outlined on
plans . Runoff will be transported by vegetated swales
constructed with 6: 1 side slopes . The exterior ditch along the
north property line will have a 3 : 1 outside slope with a 5: 1
inside slope. The proposed curb & gutter is designed to
protect the shoulders and planters from vehicles cutting
across the radius, not for channeling or conveyance of storm
water. Sod will be placed at locations where runoff flows off
the parking areas for immediate stabilization.

A low density project is one that meets the appropriate criteria for built upon a and transp,&ts-stormwate
runoff primarily through vegetated conveyances. Low density projects should not have a discrete stonnwater
collection system as defined by 15A NCAC 2H .1002(18). Low density requirements and density factors can
be found in 15A NCAC 2H .1005 through .1007.

• 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. Lots - the total number of lots in the subdivision.
• BUA/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.
