High Density Stormwater Project
Leland, NC
Dear Mr. Smith,
The Town of Leland Public Services Department received a complete Stormwater Management Permit
Application for the project entitled The Townes at Seabrooke on August 8, 2022. Staff review of the plans
and specifications has determined that the project,as proposed,will comply with the Stormwater
Regulations set forth in Chapter 26 of the Town of Leland Code of Ordinances.We are forwarding Permit
No.22-09 dated August 17,2022 for the construction of the project.
This correspondence,the attached permit, and the attached stamped approved plans,together with the
supplemental calculation and materials submitted, constitute the approval permit for the proposed project.
Please note that the permit is issued based on determinations of seasonal high-water table (SHWT) and
infiltration rates as indicated in submitted reports. Variations in these characteristics should be monitored
routinely,as they may alter the effectiveness of the stormwater control measures.
This permit shall be effective from the date of issuance until rescinded and shall be subject to the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 supersede 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 applicable,the appropriate deed restrictions must also
be recorded for the subject property. Also,when the project is complete be sure to fill out the Designer's
Certification for the stormwater system.

An approved plan shall become null and void if the applicant fails to make substantial progress on the site
within 18 months after the date of approval. The stormwater administrator may grant a single,one-year
extension of this time limit,for good cause shown, upon receiving a written request from the applicant
before the expiration of the approved plan. In granting an extension,the stormwater administrator may
require compliance with standards adopted since the original application was submitted unless there has
been substantial reliance on the original permit and the change in standards would infringe the applicant's
vested rights.
If any parts, requirements,or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon request within thirty(30) days following receipt of this permit.This
request must be in the form of a written petition, conforming to Chapter 150E of the North Carolina
General Statutes, and filed with the Clerk of the Town of Leland, 102 Town Hall Dr., Leland, NC 28451.
Unless such demands are made this permit shall be final and binding.
If you have any questions or need additional information concerning this matter, please contact me at
