NC DWR
401 & Buffer Permitting Branch
Attn: Karen Higgins
512 North Salisbury Street
Raleigh, NC 27604
We request the use of Nationwide Permit 3 for proposed impacts to a jurisdictional
stream exiting the dam of Robinwood Lake. Robinwood Lake is located off Robinwood
Road in Gastonia, NC. The street address of the parcel in question is 2221 Robinwood
Road (35.23501,-81.15735). The parcel in question, approximately 106 acres in size, is
shown on the attached USGS Topo Quad vicinity map and Soil Survey of Gaston
County.
Gaston County Family YMCA owns the subject property and proposes construction of a
new YMCA facility. The facility will include gym areas, offices, etc as well as outdoor
soccer fields. As part of the development the YMCA plans use of Robinwood Lake for
water related activities such as boating, swimming, and fishing. Due to the age and shape
of the existing dam constructed in 1947, project engineers plan to rehabilitate the feature
for safety and maintenance purposes. Existing dam slopes are approximately 1:1.5 with
post construction slopes planned at 1:4.
Specifically we request 801f of permanent stream impact associated with extension of the
dam. Project engineers plan to abandon the existing 8" pipe and install a new 4" pipe to
drain the lake. Extension of the dam to reduce slope for maintenance purposes will result
in fill of the proposed 801f of stream. A headwall has been incorporated in the dam
design to limit stream impacts to the minimum needed. The stream in question is of low
quality in relation to habitat for aquatic life (little substrate, vertical banks, lack of shade).

Gaston Natural Resources Department received a complete Stormwater Control Plan for the
above project . Staff review of the plans and specifications determined that the project, as
proposed, will comply with Gaston County's Stormwater Ordinance. The Gaston County
Stormwater Permit ( 147 ) isaaaroved.
Your Stormwater Permit shall be effective from the date of issuance and shall be subject to
the conditions and limitations as specified therein. Please pay special attention to your
Operation and Maintenance requirements. Failure to establish an adequate system for
operation and maintenance of the stormwater management system will result in future
compliance problems.
Section 11, As -built Plans and Specifications, of the Stormwater Ordinance shall be validated
at completion of the project. Note that a Certificate of Compliance or Occupancy will not be
issued without as -built plans or certification of previously submitted plans.
Be advised of the annual inspection report, maintenance agreement/restrictive covenant, and
record easements for access, maintenance, and inspections required under Section 18,
Assurance that Improvements will be Maintained, in Gaston County's Stormwater Ordinance.
If any parts, requirements, or limitations contained in this permit are unacceptable, or you need
additional information concerning this permit, please contact Gaston Natural Resources
Stormwater Division at [phone]. We look forward to working with you throughout this
project.
This approved plan shall become null and void if no progress is realized on-site within six months
after the date of approval (Section 7.p). If any parts, requirements, or limitations contained in this
permit are unacceptable, or you need additional information concerning this permit, please
contact Gaston Natural Resources Stormwater Division at [phone]. We look forward to
working with you throughout this project.

The Erosion and Sedimentation Control Plan submitted for the above project has been
reviewed and is approved.
Please be advised that the Ordinance (Section 18 (c) and Title 15 NCAC
046.0127(b) requires that a copy of the approved Soil Erosion & Sedimentation Control
Plan be on file at the job site. This letter is also Notice required by the Ordinance
(Section 21) and G.S. 113A-61.1 of our right of periodic inspection to insure compliance with
the approved plan.
Enclosed is an NPDES Stormwater Discharge Permit for Construction Activities, which is
tied to this approved plan.
Also, enclosed is your Certificate of Approved Plan that must be posted on the primary
entrance of the job site before construction begins and until establishment of permanent
groundcover. ,
After commencement of this project, if it is determined that the Soil Erosion &
Sedimentation Control Plan is inadequate to meet the reqirements of the Ordinance (Section 18
(c)(f) and G.S. 113A-51 through 66), this office may require revisions to the Plan and
implementation of the revisions to insure compliance.
Please note that this approval is based in part on the accuracy of the information provided in the
Financial Responsibility Form which you have provided. You are requested to file an amended
form if there are any changes in the information included on the form. Please notify our office
(704-9224181) at least 48 hours before commencement of the land -disturbing
activity. (Ordinance Section 8 (e).
