Laurel Bay
Low Density Stormwater Project
Dare County
The Washington Regional Office received a complete Stormwater Management
Permit Application for the Laurel Bay project on April 22, 2019. 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

This permit shall be effective from the date of issuance until rescinded, and shall
be subject to the conditions and limitations as specified therein, and does not supercede
any other agency permit that may be required. Please pay special attention to the
Operation and Maintenance requirements in this permit. Failure to establish an adequate
system for operation and maintenance of the stormwater management system will result
in 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,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
