Subject: REQUEST FOR ADDITIONAL INFORMATION
Avondale Subdivision
Dear Mr. Wallace:
On October 30, 2019, the Division of Water Resources — Water Quality Programs (Division) received your
application dated October 14, 2019, requesting a 401 Water Quality Certification and Buffer
Authorization from the Division for your project. The Division has determined that your application is
incomplete and cannot be processed. The application is on -hold until all of the following information is
received:
The buffers are regulated by the City and not DWR. Please ensure that you secure the
appropriate buffer authorizations/approvals as necessary as the 401 will solely be for stream
and wetland impacts. Also note that during the USACE/DWR site visit we did not confirm the
start point of the stream that you are proposing to cross. This must be done by the local
government in the field and then should be surveyed and shown on the plans so that the
appropriate buffers may be shown. Depending on where the location of the start point it
buffers may affect some lots in a way that limits development
2. On Sheet C1 at the very western edge of the property there are some lines that appear that they
may be a utility corridor, but the scale is too small to read any of the text. Can you please
confirm what these areas are and whether there are any new impacts to streams, wetlands or
buffers from any new activities in this location. [15A NCAC 02H .0502(g)]
3. Sheet C1 does not appear to include all wetlands found on the property, specifically there
appear to be some wetland areas missing along the property boundary with Sumner Church Rd.
Please update the plans to include all the features found during the USACE/DWR site visit. [15A
NCAC 02H .0502(g)]

4. Per Condition 11.9 of GC 4139, all work must be done "in the dry". Therefore, dewatering
methods will be necessary to temporarily dewater the stream channel during pipe installation.
Please provide a construction sequence that details the method of dewatering to be utilized at
the site and the sequence of construction events to be followed to ensure compliance with this
condition. In addition, please ensure that the location of the temporary impacts are shown on
the construction drawings and clearly indicated in the revised impact table. [15A NCAC 02H
.0502(b)(3)]
Pursuant to Title 15A NCAC 02H .0502(e), the applicant shall furnish all of the above requested
information for the proper consideration of the application. Please respond in writing within 30
calendar days of receipt of this letter by sending one (1) copy of all of the above requested information
to the 401 & Buffer Permitting Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617 OR by
submitting all of the above requested information through this
link: https://edocs.deg.nc.gov/Forms/Supplemental-Information-Form (note the DWR# requested on
the link is referenced above).
If all of the requested information is not received within 30 calendar days of receipt of this letter, the
Division will be unable to approve the application and it will be denied as incomplete. The denial of this
project will necessitate reapplication to the Division for approval, including a complete application
package and the appropriate fee.
Please be aware that you have no authorization under the Water Quality Certification Rules for this
activity and any work done within waters of the state may be a violation of North Carolina General
Statutes and Administrative Code.
