DWQ Project # 06-0888, Ver. 2
Johnston County
CERTIFIED MAIL: RETURN RECEIPT REQUESTED
Mr. Will Moore
TWM Properties, LLC
808 Parkridge Drive
Clayton, NC 27527
Subject Property: Dolts Lake West Subdivision
Holts Lake (Black Creek) [030404, 27-45-(14), C, NSW]
REQUEST FOR MORE INFORMATION
Dear Mr. Moore:
On May 7, 2007, the Division of Water Quality (DWQ) received your application dated April 25, 2007, to
fill or otherwise impact 0.1854 acres of 404/wetland, and 0.3929 acres of open waters (pond), and 0.00
square feet of Zone 1 Neuse River basin protected riparian buffers and 0.00 square feet of Zone 2 Neuse
River basin protected riparian buffers to construct a residential subdivision. The DWQ has determined
that your application was incomplete and/or provided inaccurate information as discussed below. The
DWQ will require additional information in order to process your application to impact protected
wetlands and/or streams on the subject property. Therefore; unless we receive five copies of tttc
additional information requested below, we will have to move toward denial of your application as
required by I SA NCAC 2H .0506 and will place this project on hold as incomplete until we receive this
additional information. Please provide the following information so that we may continue to review your
project.
Additional Information Requested:
1. The wetland impact labeled as "Site 2" on the plans does not appear to be necessary. Please
eliminate the wetland impact or provide additional information as to why it is necessary for this
project. It appears that the lot is buildable without the wetland impact on Lot 49.
2. This Oftice believes that lots labeled on the plans as " 39" and "40" can be moved or reconfigured
to avoid the impacts to the wetland next to the pond. Please revise the plans to avoid the impacts.
3. Drainage ditches:
Please number the drainage ditches on the Site Plan and Overall Subdivision Layout Sheet (SP-
l ). It is very difficult for the DWQ to match the calculations with the appropriate drainage ditch.
Please provide clearly labeled cross-sectional details of each of the proposed drainage ditches as
well as velocity calculations. In order to discharge to the wetlands, anon-erosive velocity of less
than 2.0 feet per second during the l0-year, 24-hour storm must he established. Please provide

all the calculations needed to demonstrate that an appropriate velocity has been established at
every proposed outfall to wetlands. Please clearly label each set of calculations so that the DWQ
can easily match the calculations with the ditch to which they apply.
4. Diffuse flow to riparian buffers:
Please show how diffuse flow has been established to riparian buffers on this project. Per 1 SA
NCAC 213 .0233, concentrated flow from the road, driveways and rooftops must be converted to
diffuse flow before it is allowed to discharge through the riparian buffer. If one or more level
spreaders is proposed, please provide a DWQ Level Spreader Worksheet (available on the 401
web site) for each one as well as all of the Required Items listed in the worksheet.
Please submit this information within 30 calendar days of the date of this letter. If we do not receive this
requested information within 30 calendar days of the date of this letter, your project will be withdrawn
and you will need to reapply with a new application and a new fee.
This letter only addresses the application review and does not authorize any impacts to wetlands, waters
or protected buffers. Please be aware that any impacts requested within your application are not
authorized (at this time) by the DWQ. Please call Ms. Cyndi Karoly or Mr. Ian McMillan at 919-733-
1786 if you have any questions regarding or would like to set up a meeting to discuss this matter.
Sincerely,
Cyndi Karoly, Supervisar
