MEMORANDUM
NORTH CAROLINA
Enlrhvnmrntal Quality
May 30, 2019
To: Scott Cole, P.E., Division Engineer, NCDOT Division 12
From: Donna Hood, Division of Water Resources
Subject: Response to the Indirect and Cumulative Effects Assessment Northcross Drive Extension,
Mecklenburg County, TIP U-5108.
This office has reviewed the referenced document dated May 7, 2019. The NC Division of Water Resources
(NCDWR) is responsible for the issuance of the Section 401 Water Quality Certification for activities that impact
Waters of the U.S., including wetlands. Under 15A NAC 2H .0500 (.0506[4]), it is the NCDWR's responsibility to
ensure that projects do not result in cumulative effects or cause a violation of downstream water quality based on
reasonably anticipated future impacts.
Upon reviewing the information provided in the referenced document, The NCDWR has concluded that the analysis
performed is sufficient and no further analysis is warranted at this time.. However, please keep us apprised of any
additional information or revisions to the indirect and cumulative impact document(s). This decision is based on
information currently provided to us; this decision may change based on updated or new information.
As described in the report, additional development that occurs as an indirect impact will be covered under state
permitted, locally administered phase Il stormwater programs of the Towns of Huntersville and Cornelius. These
programs should address any additional stormwater discharge from anticipated development. However, it is highly
recommended that there be control of access and future development be limited as much as possible to help ensure
the protection of the McDowell Creek Watershed, a major source of surface water to Mountain Island Lake,
drinking water source for the greater Charlotte metropolitan area. Mecklenburg County Land Use and
Environmental Agency has targeted this watershed for protection over the last twenty years by limiting development
and investing in over $15 million public dollars to restore and maintain current conditions.
Thank you for requesting our input at this time. The NCDOT is reminded that issuance of a 401 Water Quality
Certification requires that appropriate measures be instituted to ensure that water quality standards are met and
designated uses are not degraded or lost. If you have any questions or require additional information, please contact
Donna Hood at [phone] or [e-mail].
