Subject: REQUEST FOR ADDITIONAL INFORMATION
Worthdale Park Stream Restoration and Stormwater Control Measure (SCM)
Retrofit
Dear Mr. Eckhardt:
On January 8, 2024, the Division of Water Resources (Division) received your application requesting a
401 Individual Water Quality Certification from the Division for the subject 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:
1. Tree planting should be conducted in the appropriate tree planting season to ensure survival of
planted stems. DWR would appreciate confirmation on when planting will occur.
2. DWR requests that you consider including additional canopy species in the upper wetland area.
3. The application identifies SCM grading within the riparian buffer as "temporary" impacts. All
aspects of the SCM must be identified as permanent SCM impacts, including the graded fill slopes
that will be vegetated. Please update the plans and table of impacts accordingly.
Comments Specific to Plan Sheets:
4. Depict wetlands on the Stream Plan and Profile sheets. Include the greenway stream crossing on
the stream plans and planting plans as well.
5. DWR requests that the wattle spec be updated to include staples in order to be effective.
6. On Plan Sheet 1.4.1 there is a note for temporary gravel area for sewer line construction. Please
provide information on what the sewer construction entails such as timing of construction, is it a
replacement or is a new line being installed? More information is necessary for us to adequately

review the project. Please also clarify whether this construction activity will take place at the same
time as the stream construction activities and whether the gravel will be removed and if so, what
measures will be taken to ensure any compaction of the area is addressed to improve permeability
and future vegetation growth.
Additional Review Items to consider that do not need responses:
7. These are deep floodplain depressions. In some areas they are being excavated by 5-7 ft. Is there a
reason for this depth? DWR is concerned that wetland vegetation will not establish in the depths
proposed in this plan and recommends limiting pools to 18" or reclassifying areas as open water.
8. Is it necessary to have a rock lined "enhanced wetland outlet" or rip -rap channels connecting
wetlands to streams? Could this be achieved with a vegetated swale?
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 Section 401 of the Clean Water Act for this
activity and any work done within waters of the state may be a violation of North Carolina General
