M ikayla,
Thank you for providing the additional information. Please see my additional comments and
questions below.
• The agent authorization letter must be signed by the agent and the landowner. Please update
the agent authorization letter with both signatures. [15A NCAC 02H .0502(a)(11)].
• The revised stream impact table needs additional clarification.
a S1:The stream impact to install the culvert is shown as 188 LF to account for the loss of
stream channel to be placed in a culvert. Thank you for updating this to reflect the loss
of stream channel.
o S2: The temporary dewatering impacts should only include the impacts to dewater the
stream — such as where the impervious dike and pump is installed at the upstream
location, along with the footprint to install the energy dissipation apron at the
downstream location. Please update the impact table to reflect the linear feet of
impact necessary for dewatering.
o S3: The table shows 188 LF rip rap proposed- is this correct? I am assuming that the rip
rap fill is for the headwall area upstream from the culvert inlet. Please update the
impact table to reflect the linear feet of proposed rip rap below the ordinary high water
line.
• In order to show your project will be in compliance with Condition 17 in GC 4256, please
provide a detail showing the proper installation (below the streambed elevation) of the
proposed riprap pad at the culvert inlet. [15A NCAC 02H .0502(a) and (c)].
o I did not see a detail on sheet C3.0 showing how the rip rap pad at the culvert inlet will
be installed below the streambed elevation. Is it on a different plan sheet? If not,
please update the plan set to reflect this condition.
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 provide your response by
January 14. 2021. If all of the requested information is not received, 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.
