City of Wilmington / County of New Hanover

The City of Wilmington is the permitting authority for all land disturbing activities and requires the land owner to maintain all on-site stormwater control facilities and all open space areas (e.g. parks or “green” areas) required by the approved stormwater control plan. The City of Wilmington will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. Post-construction stormwater regulations and any applicable stormwater utility fees will also be enforced and collected by the city. The City of Wilmington, under the NPDES program, also has the authority to inspect properties for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite.

Sec. 18-782. Operation and maintenance agreement

Prior to the conveyance or transfer of any lot or building site to be served by a structural BMP pursuant to this ordinance, and prior to issuance of any permit for development or redevelopment requiring a structural BMP pursuant to this ordinance, the applicant or owner of the site must execute an operation and maintenance agreement that shall be binding on all subsequent owners of the site, portions of the site, and lots or parcels served by the structural BMP. Until the transference of all property, sites, or lots served by the structural BMP, the original owner or applicant shall have primary responsibility for carrying out the provisions of the maintenance agreement.

The operation and maintenance agreement shall require the owner or owners to maintain, repair and, if necessary, reconstruct the structural BMP, and shall state the terms, conditions, and schedule of maintenance for the structural BMP. In addition, it shall grant to city a right of entry in the event that the City Manager or his designee has reason to believe it has become necessary to inspect, monitor, maintain, repair, or reconstruct the structural BMP; however, in no case shall the right of entry, of itself, confer an obligation on city to assume responsibility for the structural BMP.

Special requirement for HOA’s and other associations. For all structural BMPs required pursuant to this ordinance and that are to be or are owned and maintained by a homeowner association, property owner association, or similar entity, the required operation and maintenance agreement shall include all oftl1e following provisions:

(2) Granting to the city a right of entry to inspect, monitor, maintain, repair, and reconstruct structural BMPs.

(3) Allowing the city to recover from the association and its members any and all costs the city expends to maintain or repair the structural BMPs or to correct any operational deficiencies. Failure to pay the city all of its expended costs, after forty-five (45) –days written notice, shall constitute a breach of the agreement. In case of a deficiency, the city shall thereafter be entitled to bring an action against the association and its members to pay, or foreclose upon the lien hereby authorized by the agreement against the property, or both. Interest, collection costs, and attorney fees shall be added to the recovery.

(4) A statement that this agreement shall not obligate the city to maintain or repair any structural BMPs, and the city shall not be liable to any person for the condition or operation of structural BMPs.
