STORMWATER MANAGEMENT PLAN APPROVAL
Dear Mr. Barron:
Chatham County
DWQ Project No. 05-0732v15
On January 11, 2008, the Division of Water Quality (DWQ) issued a revised 401 Water Quality
Certification to temporarily impact 339 linear feet of stream and 0.157 acre of 404 wetlands and to
permanently impact 1,666 linear feet of stream and 0.1590 acre of 404 wetlands in order to construct the
Briar Chapel Subdivision in Chatham County.
In order to meet Condition 10 of the 401 Certification for this project, a stormwater management plan for
Briar Chapel - Granite Mill Boulevard, dated February 17, 2010, was received by the DWQ on February
18, 2010. This stormwater management plan for the Granite Mill Boulevard section of the Briar Chapel
development has been reviewed and satisfies the stormwater management condition of the 401 Water
Quality Certification as a low density project. You are required to meet the following conditions:
The stormwater management system (consisting of a bioretention area and all associated
appurtenances), all stormwater conveyances and the grading and drainage patterns depicted on
the plans, as approved by this office must be maintained in perpetuity. No changes to the
structural stormwater practices shall be made without written authorization from the DWQ. The
stormwater management structures shall have maintenance access 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.
2. All operation and maintenance activities shall be followed as stipulated in the Operation and
Maintenance Agreement signed and notarized on February 17, 2010, and received in our office on
February 19, 2010.
