This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater
runoff as described in Sections 1.6 and 1.7 on pages 3 and 4 of this permit. The
stormwater controls have been designed to handle the runoff generated by a 3"
design storm from the maximum amount of built -upon area as indicated in
Sections 1.6 and 1.7 on pages 3 and 4 of this permit, therefore, a vegetated filter
and offline bypass are not required.
3. The tract will be limited to the amount of built -upon area indicated in Sections 1.6
and 1.7 on pages 3 and 4 of this permit, and per approved plans.
4. All stormwater collection and treatment systems must be located in either
dedicated common areas or recorded easements. The final plats for the project
will be recorded showing all such required easements, in accordance with the
approved plans.
5. The runoff from all built -upon area within the permitted drainage areas of this
project must be directed into the appropriate permitted stormwater control
system.

The Commons at Calabash SW8 060511
Subject: The Commons at Calabash SW8 060511
From: Linda Lewis <[e-mail]> '
Date: Tue, 07 Nov 2006 07:47:48 -0500
To: Richard Collier <[e-mail]>
Richard:
I have reviewed the information for the subject project which was resubmitted on
August 17, 2006.
Within Drainage Area 410, only the runoff from 1/2 of the building is being
collected and sent to the proposed basin. while I can certainly understand that
the portion of sidewalk in front of the building cannot be collected, surely the
roof drains for the entire building can be directed into the basin. If no roof
drains were originally proposed, perhaps roof drains need to be added to the
building design.
This revision will require a change to the calculations for Basin #10 (increasing
DA & BUA) a change to the DA and BUA listed for Basin #10 in Section I11.6 of the
application, and a revised drainage area map.
Other than that, I'm ready to issue this permit.

Reference: Double Ring Infiltrom.eter Testing
R.agozzino Site
Thomasboro Road @ N.C. Highway 179
Calabash, North Carolina
Job No. 1063-03-709
Dear Mr. Norris:
As requested, S&ME personnel have recently conducted field testing of the surficial soils at the
subject site at the approximate location shown in Figure 1. Specifically, our representatives
performed the following work items on May 21, 2003:
1. Advanced two hand -angered borings at the proposed surface
water infiltration area in order to visually classify the in -place
soils. A Munsell Soil Color Chart was used to define the hue and
chrorna of the recovered soil samples.
2. Conducted double -ring infillrometer' testing at a depth of 28
inches below the existing ground surface at Location 1. This
testing was conducted in general accordance with American
Society for Testing and Materials (ASTM) procedure D--3385
entitled, "Infiltration Rate of Soils in Field Using Double -Ring
111filtroimter".
Based on our field classifications of the excavated soils at the hand-augered boring
locations, the in -place soils consist of a 4 to 12-inch thick surf eial layer of slightly silty sands with
organics. These surficial soils were underlain by weakly cemented slightly silty sands that extended
to depths ranging from about 14 to 22 inches below the existing ground surface. Slightly silty sands
were then encountered and extended to the maximum completed boring depth of 70 inches, Water
was encountered at Location i at a depth of approximately 61 inches below the existing ground
surface. The site water -level will fluctuate with climatic and seasonal conditions, however, acid may
be higher or lower at other times of the year. it is our opinion that the depth to the seasonal high
water table is about 4 feet below the existing ground surface.. However, the presence of. weakly
cemented sands in the tipper 2 feet suggests that a perched water table could occur within the upper
2 feet after periods of heavy or extended rainfall.

In response to your April 22, 2005 email requesting additional information, we offer the
following:
Please complete one column on the application for each proposed infiltration basin and trench.
a. A column has now been completed on the application for each infiltration basin and
trench.
2. Please initial page 2 of each basin supplement and pages 2 & 3 of each trench supplement.
a. The supplements have been initialed on noted pages.
3. Section IV on page 2 of the Infiltration Basin sitpplentents is incorrectly titled as the
"Undergronnd Infiltration Trench Operation and Maintenance Agreement", and Iists the
maintenance items for an infiltration trench. Please correct the title to "Infiltration Basin
Operation and Maintenance Agreement", and list the correct maintenance items, per the attached
PDF format supplement.
Section IV on page 2 of the Infiltration Basin supplements has been corrected to
"Infiltration Basin Operation and Maintenance Agreement" with appropriate listing
of maintenance items.
4. Please dimension the parking areas and sidewalks.
a. Parking and sidewalk dimensions now are shown on the plan.
5. No BUA has been assigned to Please Z. Please either account for this fuhrre please nozo in this
system, or note on the plans that Phase 2 will provide its own. stormwater. Please note that if
Please 2 is not accounted for now, the permit will require you submit a modification to the permit
prior to development, or to record a deed restriction prior to the sale of that area, statng that the
lot is subject to state stormwater pertn.it requirements regardless of the amount of acreage
disturbed, and must obtain a permit from the Division of Water Qtialih/ prior to any
construction.
a. A note has been added to the plan stating that Phase 2 stormwater will be provided
at a later date.

6. The summary of the proposed treatment in Section III of the application indicates that there will
be infiltration basins and underground "retention" pipes. I believe this should be corrected to
underground "infiltration" pipes. Are yorc proposing solid piped storage systems that feed the
basins and trenches? If yes, please clearly identify these areas on the plans.
a. The summary in Section III of the application has been corrected to "infiltration"
pipes.
7. Please provide bypass structure details. All runoff in excess of the design storm must bypass the
system prior to entering the basin or trench, not after.
a. The system has been designed for twice the 1.5" design storm; therefore bypassing
the system is not required.
8. Infiltration trenches must be 4 times wider than they are tall. This promotes dispersion of the
runoff over a wider area to be infiltrated, and is a required design parameter. The proposed
trenches are only 5 x 5 and 6 x 6.
a. The infiltration trenches have been revised to be 4 times wider than tall.
9. Please distension each line and arc of the bottom contour in each infiltration area.
a. The bottom contour of each infiltration basin has been dimensioned and is shown on
the plan.
10. Please provide details of how the catch basins are connected to the proposed trench systems. A
header pipe is necessary to insure good dispersion of the runoff into both infiltration pipes.
a. Catch basin detail is shown on the detail sheet. The infiltration system layouts have
been revised and header pipes have been provided.
If you have any questions or require clarification, please do not hesitate to contact me.
Sincerely,

Tim:
The Division received a stormwater management permit application for the subject
project on April. 19, 2005. The application is incomplete and cannot be accepted for
review until the following items are submitted/addressed:
1. Please complete one column on the application for each proposed infiltration
basin and trench.
2. Please initial page 2 of each basin supplement and pages 2 & 3 of each trench
supplement.
l_J Section IV on page 2 of the Infiltration Basin supplements is incorrectly titled
as the "Underground Infiltration Trench Operation and Maintenance Agreement", and
lists the maintenance items for an infiiltration trench. Please correct the title
to "Infiltration Basin operation and Maintenance Agreement, and list the correct
maintenance items, per the attached PDP format supplement.
4. Please dimension the parking areas and sidewalks
S. No BUA has been assigned to Phase 2. Please either account for this future phase
now in this system, or note on the plans that Phase 2 will provide it's own
stormwater. Please note that if Phase 2 is not accounted for now, the permit will
require you submit a modification to the permit prior to development, or to record
a deed restriction prior to the sale of that area, stating that the lot is subject
to state stormwater permit requiements regardless of the amount of acreage
disturbed, and must obtain a permit from the Division of water Quality prior to any
construction.

Dear Mr. Ragozzino:
Your recent stormwater management permit application and check #106078 for the $420.00 application
fee are being returned because the application lacked the necessary basic elements to accept it for
review. Additional information was requested via email on April 18, 2005, and again on June 8, 2005.
No response to either of those requests was received. The plans and any other documentation that
were submitted have been discarded or recycled, as appropriate. Please address the following noted
deficiencies and provide the requested information:
® Complete one column on the application for each proposed.infiltration basin and trench.
® Initial page 2 of each basin supplement, and pages 2 & 3 of each trench supplement.
® Provide corrected Infiltration Basin supplements. It appears that the Operation and Maintenance
part in Section IV is labeled for a Trench system rather than a Basin system.
® Dimension the parking areas and sidewalks.
Account for the built -upon area for Phase 2 or indicate that Phase 2 will provide it's own
stormwater controls at a later date.
® There appears to be some confusion regarding the nature of the underground storage being
proposed. Are they solid pipes or perforated infiltration pipes?
® Provide bypass structure details. All runoff in excess of the design storm must bypass the
system.
® Make the width of the infiltration trenches at least 4.times their height.
® Dimension each line and arc of the bottom contour in each basin.
® Provide details of how the trenches are connected to the catch basins.
Please resubmit the permit application package to the address below. Note that the 90-day statutory
permit review time begins upon receipt of a complete application. if you have any questions, please do
not hesitate to call me at [phone].
