Stormwater O&M Agreements
Prior to the conveyance or transfer of any lot or building site or issuance of any development permit for a development to be served by a structural BMP required by the Design and Construction Ordinance, developers are required to execute and record operation and maintenance agreements to ensure that owners maintain and operate the BMP facility to preserve and continue its function for which it was originally designed. Operation and maintenance agreements require BMP owners to properly maintain, repair and, if necessary, reconstruct the BMP and provide a schedule for the maintenance frequency for the facility. Operation and maintenance agreements must be recorded with the Wake County register of Deeds upon final plat approval and recorded copies must be submitted to the Town within fourteen days following recordation.

If an owner chooses to also do their own, complete reports must include the forms and information below. The Town of Morrisville National Pollution Discharge Elimination System Phase II Stormwater Permit requires that structural BMPs be inspected annually to preserve and continue their function in controlling stormwater runoff quality and quantity at the degree or amount of function for which the structural BMP was designed. Additionally, stormwater BMPs must be periodically inspected per the frequency specified in the recorded operation and maintenance agreement for the facilities.
