RiskHydro partnered with the MacTavish Subdivision Homeowners Association to complete the annual Emergency Action Plan (EAP) update for the Rosewood Subdivision Dam, a High Hazard structure located in Raleigh, North Carolina. The dam presents a complex risk profile due to a second dam located directly downstream, which creates cascading failure conditions that the EAP must account for clearly. RiskHydro reviewed the existing documentation, updated contacts and emergency procedures, and coordinated with Wake County Emergency Management to produce a fully compliant submittal. The EAP was approved by NCDEQ Dam Safety on the first submittal, keeping the HOA in good standing with minimal administrative effort.

The Rosewood Subdivision Dam is classified as a High Hazard structure under North Carolina Dam Safety regulations, reflecting the potential downstream consequences if the dam were to fail. Homes, roads, and utilities in the subdivision sit within the inundation zone, and the presence of another dam directly downstream creates a cascading failure scenario that adds complexity to the emergency planning requirements.
North Carolina requires annual EAP updates for dams in this classification to ensure that emergency contacts, notification procedures, and hazard assessments stay current. The HOA needed a technically accurate, regulator-ready document that met NCDEQ formatting standards, reflected current downstream conditions, and clearly addressed the cascading failure scenario, all without placing an undue administrative burden on volunteer HOA leadership.
RiskHydro completed a thorough desktop review of the prior EAP and supporting documentation before beginning the update. That review confirmed that the existing inundation mapping and failure analysis remained valid, which meant the update could focus on the procedural and contact elements without requiring new hydraulic modeling. Key tasks included:
The updated EAP was approved by NCDEQ Dam Safety on the first submittal, no revision cycles required. The HOA now has a current, regulator-ready document that emergency responders can follow during an actual incident and that HOA leadership can update each year without starting from scratch.
“Matt previously prepared our dam’s Emergency Action Plan and later completed the annual update through RiskHydro – both were approved on the initial submittal. He was responsive, clear in his communication, and made the process straightforward for our HOA.” – Stori Bartle, HOA President
