Subject: Stormwater Permit Renewal
Stormwater Management Permit SW7080704
Bowsertown Landing Residential Development
Dare County
Dear Mr. Outten:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7080704 for a stormwater treatment system consisting of an
infiltration system to serve a proposed Bowsertown Landing Residential Development to
be located at 170 South California Road, Manteo, NC expires on December 30, 2021.
This is a reminder that permit renewal applications are due 180 days prior to expiration.
We do not have a record of receiving a renewal application.
If you wish to maintain the permit, please submit a completed permit renewal application
along with a $505.00 fee for permit renewal. Permit application forms for renewal can be
found on our website at: https://deq.nc.gov/about/divisions/energy-mineral-and-land-
resources/stormwater/stormwater-program/post-constructioii-2. North Carolina General
Statutes and the Coastal Stormwater rules require that this property be covered under a
stormwater permit if the project is constructed, If the project will not be built you may
request that the permit to be rescinded.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application forms. You can request a copy by e-mailing me at

Stormwater Management Plan — Narrative
Bowsertown Landing Residential Development OCT 0 5 2009
Roanoke Island, Dare County, North Carolina
October 1, 2009
Reference calculation sheets I through 5 for detailed information
Plan Intent:
This plan intends to capture, store and infiltrate the runoff from all impervious surfaces
for a 1.5 inch rainfall event with no off site or adjacent surface water impacts.
Infiltration areas include infiltration swales, infiltration basins and a perforated pipe roof
gutter collection system. All infiltration areas are graded to provide.Z�� to the
seasonal high water table elevation.
No overflow measures are provided and as a result the system has been sized to store and
'Tn—filtratea 3.01 inch rainfall event (twice the required design storm) in accordance with
regional practices.
Key Design Considerations:
• Seasonal Water Table Elevation - Based on monitor well reports provided by
S&ME as well as subsequent on site inspections, the seasonal high water table has
been established at 1.0' (NAVD 1988). This elevation accounts for normal tidal
fluctuations and a slight rise in water table elevation expected with the removal of
the site trees. See calculation sheet 2 for additional information.
• Soil Infiltration Rates - Based on saturated hydraulic conductivity established by
S&ME (from on site slug tests) the soil infiltration rates range from 7.5 inches per
hour to 8.5 inches per hour. 7.5 inches per hour has been used in the drawdown
calculations and the open space considerations. See calculation sheet 2 for
additional information.
• Drainage Basins Established - Two drainage basins have been established.
Drainage Basin I includes all of the impervious surfaces including roadways,
driveways, buildings, decks and stairways. Drainage Basin 2 includes all open,
buffer and greens spaces remaining at build out. See calculation sheet 3 for basin
identification and area.
• Minimum Grades Established - The overall site, less the wetlands, will be filled
to a minimum grade of 4.0' (NAVD 1988). The minimum grade of the infiltration
swales, basins and gutter collection perforated piping has been set at 3.0' (NAVD
1988) thereby allowing 24" of separation to the seasonal high water table.
Calculations and Methodology:
• Stormwater Runoff Generated by Impervious Surfaces - Within drainage
basin 1, runoff volumes were calculated by the assumption that 90% — 95% of the
1.5 inch design storm runs off the surfaces and is collected within the-infi iQ n
es' cu.
-i f
system. The runoff volumes expected for a 1.5 inch d ign s orm t4 4 ft
cu. )
• Stormwater Runoff Generated by Open, Buffer and Green Sp in
drainage basin 2 given the high infiltration rates of the soils (7.5 inches per hour)
and the overall lack of topological grade within the site, a 1.5 inch storm event

will not generate off site runoff. This conclusion is based on experience with
similar sites and is supported by HEC/RAS calculations (see calculation sheet 5).
Infiltration Area Storage Volumes - The infiltration system storage volumes
include the volume in the open swgl s, the open basins and the perforated gutter
collection piping. Interstitial storage and stora—Ce in —the roadway cu�lvertsystem
has not been included in the calculations. The minimum grade of all infiltration
t, has been set at 3.0' (NAVD 1988). Computed storage volume is
5 ,c`7 hich is over twice the volume required for the 1.5 inch design
4 (4- R,eq 0,866 cu. R.
u :ft
c
s torr
torm. see plan sheet 2 and calculation sheet 4 for additional information)
Infiltration Volume Drawdown — Drawdown has been calculated using the
basin bottom area applied to the 7.5 inches per hour soil infiltration rate. The
drawdown computed for a 1.5 inch design storm is 1.71 hours. The drawdown
computed for the 3.01 inch storm is 3.44 hours. (see calculation sheet 4 for
additional informationT—
Additional Design Considerations:
Interconnectivity of Infiltration Systems — The intent of the infiltration system
is to get the rainfall into the ground as close as possible to where it fell, avoiding
collection and the resulting problems and risks associated with runoff
concentration. The infiltration systems are distributed across the site but are
interconnected by swales and culverts. The roadway swales are separated by
driveways to allow localized infiltration. Overflow and interconnectivity across
the driveways will be established by controlling the driveway grade where it
crosses the swale. See plan sheet 2 for a driveway and swale detail.
Perforated Pipe Gutter collection system — The gutter collection system
consists of perforated disposal piping with a solid pipe overflow system. The
perforated piping will surround the buildings at an elevation invert of 3.0'
(NAVD 1988). An overflow system will be set at an overflow elevation of 4.0'
(NAVD 1988). During normal rainfall events the system will fill to the overflow
elevation before flowing into an adjacent infiltration basin. This 1.0' pressure
head will enhance the disposal capabilities of the perforated pipe which will take
advantage of the interstitial storage under and adjacent to the pipe. Note that all
buildings will be constructed on piling foundations so foundation moisture will
not be an issue.
Additional Runoff Volume Calculations — Additional runoff calculations were
prepared using HEC/RAS methodology. The 10 year, 2 hour design storm from
NOAA point precipitation estimates is 3.19 inches with the resulting post
development runoff volume computed at W,3.41cu. ft. This volume is slightly
less than the volume computed previously and is less than the storage volume
provided. See calculation sheet 5 for additional information.

I met with Mr. Mike Robinson at the Bowsertown Landing project site on September 10, 2009. We
discussed several issues regarding the proposed development, including additional information needed to
complete your stormwater application. Before a State Stormwater permit can be issued, the following additional
information is needed:
1. Provide discussion/explanation regarding. Seasonal High Water Table (SHWT) elevations, adequate
separation form SHWT, & infiltration rates.
2. Delineate/discuss drainage basins; show perimeter/green areas that do not drain to infiltration system,
Runoff calculations should match up with this discussion.
3. Revise calculations to reflect actual storage (exclude interstitial storage); revise calculations in
Supplement Sheet.
4. Expand narrative to include detailed discussion of "interconnected stormwater system", design storage
required vs. storage provided. the storm event/conditions that could generate offsite runoff, & how
this runoff might reach surface waters.
5. Revise application, supplement sheets, sw narrative, calculations & plans to reflect all changes.
The above requested information must be submitted to this office prior to October 2, 2009, or your
application will be returned as incomplete. The return of this project will necessitate resubmittal of all required
items including a new application fee. If you need additional time to complete the application package, please mail
or fax your request to this office and include any reason(s) for the time delays.
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 2H.1000 and North Carolina
General Statute 143-215.1 and may result in civil penalties of up to $25,000 per day.

(1) S&ME soils report indicates SHWT within 12-inchesof surface; NRCS soils map indicates SHWT for Johns series

sure the final design has adequate separation from SHWT. akjL-� e�..,ff

This office received a Coastal Stormwater permit application for the subject project on July 11, 2008. A
preliminary review of your project indicates that before a State Stormwater permit can be issued, the following
additional informabon is needed:
i , Based on the information provided, it appears that the proposed development exceeds 25 % BUA.
Engineered stormwater controls are required for High Density developments.
2. Swale system maintenance agreement is not signed.
3. Application does not adequately address runoff from condo buildings. Where is this water routed-, how
is it treated.
4. Show/describe outlets from proposed swale systems.
5. For low density type development, stormwater runoff should generally be treated on site through grass
swales; and vegetated buffers. Show1describe all treatment measures.
6. Revise application, supplements, narrative & plans as need to reflect changes.
The above requested information must be submitted to this office prior to October 10, 2008, or your
application will be returned as incomplete. The return of this project will necessitate resubMittal of all required

Dear Mr. Moore,
Enclosed please find a follow up submittal for the above reference project. This project
has been revised in accordance with your preliminary review and specific comments are
addressed below.
Comment 1: The BUA on this project is 19.27% based on the overall site area less the
NCDOT right of way. In addition to the roadway swales, the plan has been revised to
include additional infiltration areas. The combined storage volume of the swales and
basins are sufficient to store the first 2.3 inches of rainfall on all impervious surfaces.
Comment 2: 1 have forwarded the swale maintenance agreement to the owner and will
submit under separate cove early next week.
Comment 3: The plan has been revised to include a gutter collection which will direct
roof runoff to the basin/swale infiltration system.
Comment 4: As the storage volume denoted exceeds the 1.5 inch rainfall, no specific
outlets are proposed. Overflow volumes will sheet flow overland to the adjacent
wetlands.
Comment 5: Additional infiltration areas have been added to store and treat runoff
through infiltration.
Comment 6: All documents have been updated to reflect the current plan.
Thank you for your assistance with this project.
If you have any questions please feel free to call me at 252-255-8026. 1 can also be
