purpose of constructing the proposed development, Troutman Towne Center in Iredell County.
On January 20, 2010 and January 25, 2010, the 401 Oversight/Express Review Permitting Unit of the

January 19, 2009 (Engineer's Seal), design calculations, subsurface (soil) investigation report and
operation and maintenance (O & M) agreements dated January 7, 2010 for the two wet detention ponds

purpose of meeting Condition 7 of the 401 Water Quality Certification for this project. On February 3,
2010 and February 11, 2010, the DWQ received additional information including revised SMP sheets
dated February 2, 2010 and February 8, 2010, and O &M agreement dated February 10, 2010 for the level
spreader - filter strip system.
After carefully reviewing the information, the DWQ approves the revised SMPs dated February 2, 2010

are required to meet the following conditions:
The stormwater management system consisting of two (2) wet detention ponds and a level

without written authorization from the Division of Water Quality. The stormwater management
structures shall have maintenance access and at least a 10-foot drainage easement on each side to
allow for the ability to maintain the structures, and to perform corrective actions. The stormwater
easements shall be recorded to provide protection of the structures from potential alterations by
future property owners.
