Dear Mr. Peppler:
The Washington Regional Office received a complete Stormwater Management Permit
Application for The Reserve at Herons Ridge on February 20, 2007. Staff review of the plans
and specifications has determined that the project, as proposed, will comply with the
Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding Permit No.

subject to the conditions and limitations as specified therein. Please pay special attention to
the Operation and Maintenance requirements In this permit. Failure to establish an adequate

future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within thirty (30) days
following receipt of this permit. This request must be in the form of a written petition,

submitting a revision to the permit and receiving approval from the Division.
2. The permittee is responsible for verifying that the proposed built -upon area for the entire lot,
including driveways and sidewalks, does not exceed the allowable built -upon area. Once the
lot transfer is complete, the built -upon area may not be revised without approval from the
Division of Water Quality, and responsibility for meeting the built -upon area limit is transferred
to the individual property owner.
3. If an Architectural Review Board or Committee is required to review plans for compliance with
the BUA limit, the plans reviewed must include all proposed built -upon area. Any approvals
given by the Board do not relieve the homeowner of the responsibility to maintain compliance

specifications, and calculations prior to construction, for any modification to the approved
plans, including, but not limited to, those listed below:

5. The Director may determine that other revisions to the project should require a modification to
the permit.
6. The Director may notify the permittee when the permitted site does not meet one or more of
the minimum requirements of the permit. Within the time frame specified in the notice, the
permittee shall submit a written time schedule to the Director for modifying the site to meet
minimum requirements. The permittee shall provide copies of revised plans and certification in

operation of this permitted facility, a certification must be received from an appropriate

accordance with this permit, the approved plans and specifications, and other supporting
documentation. Any deviations from the approved plans and specifications must be noted on
