Mike,
I reviewed your talcs and could not get the 0.36 cfs with the 4" diameter orifice and a 0.5 driving head. (Don't
know). But after reviewing your continents, you are correct about the 2" diameter orifice and the driving head. I
have already made these corrections to the drawings and talcs. See attached Supp Form and Sheet 2 of 3 and 3 of 3.
Also the building area should equal 36,000 sq-ft and not 45,000. I have already made this change to the application;
see App Sheet 3.
We really appreciate you time and willingness to work with Lis on these issues. Like always, should You have any
additional continents or concerns please don't hesitate to contact me.
Thanks and have a great day.

Subject: Township Developers
Jonathan,
In reviewing discharge rate and drawdown calculations for the subject project, the proposed 4" diameter orifice
would actually have a discharge rate of about 0.36 cu. ft./sec and drawdown the pond in about half a day. To
achieve the 0.09 cu. ft./sec discharge rate as entered on the supplement form, the orifice would need to be 2",
which would also achieve the minimum 2-day drawdown as required.
Based on the difference in elevations of Temp. Pool (153.5') and Perm. Pool (152.0'), the Driving Head should be
0.5' instead of 1.25' ((153.5-152.0)/3).
Please revise the supplement and plan sheets to reflect these necessary changes. If we need to speak more
about this, please contact me.
Also, the application shows proposed buildings at 45,000 sq. ft., however the plans show buildings totaling
36,000 sq. ft. Am I missing something?
Thanks,
Mike

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Stormwater will be directed to a Wet Detention Basin located to the northwest of the site. The Basin is
designed using 90% TSS Pollutant Removal Efficiency Table 1.0-3.
2.a.If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid Building Permit Issued Date:
❑ Other: Date:
b.ldentify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW -1995 ❑ Ph It - Post Construction
3. Stormwater runoff from this project drains to the Lumber River basin.
4. Total Property Area: 6.27 acres 5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: 0 acres
Total Property Area (4) -Total Coastal Wetlands Area (5) - Total Surface Water Area (6) = Total Project
Area':6.27 acres
* Total project area shall be calculated to exclude the following: the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area is used to
calculate overall percent built upon area (BUA). Non-constal wetlands landtvaral of the NHW (m, MHW) line umy
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 =-";�r' 70 %
ML z�3,122
9. How many drainage areas does the project have? One (For high density, count 1 for each proposed
engineered stormwater BMP. For low density and other projects, use 1 for the whole property area
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.

Jonathan,
This e-mail serves as acknowledgement that the subject application has been received by our office and after a
preliminary review of the application the following items need to be addressed prior to further review.
-project is within WS-IV watershed, which only allows for a maximum of 70% BUA while application shows proposed
BUA of 79%; changes to the proposed BUA will require revisions to the main application form, supplement form and
plans and specs
-plans and specs must be signed and sealed by the licensed professional responsible for design
-submittal requirements checklist on pages 4 and 5 of the main application form are not initialed
Be advised that these items are as a result of a preliminary review and might not be all inclusive. There may be other

Our office has received a copy of the Financial Responsibility/Ownership Form (FR/O) from the Division
of Land Resources, Land Quality Section for the Township Developers, LLC project to be located in Robeson
County. Based on project location information provided on the FR/O, we have determined that the project is
subject to a State Stormwater Management Permit for development activities within one mile of and draining to
High Quality Waters (HOW).
Please be advised that construction of any built -upon areas prior to issuance of a State
Stormwater Management Permit will be considered a violation of the NC Administrative Codes and could
result in the assessment of civil penalties of up to $25,000 per day, per violation. The Stale Stormwater
Management Permit is in addition to the NPDES Stormwater General Permit (NCG010000) received for
construction activities. For more information and to obtain the application and applicable supplement forms,
please visit: http:Hwww.ncwaterquality.ore/su/state_sw.htm.
