A flood risk assessment supports plans to refurbish Tyrone County Hall in Omagh. The report states the work qualifies as minor development and includes measures to manage flood risks.

The building sits at the junction of Sedan Avenue and Mountjoy Road. It houses departments from Stormont responsible for infrastructure, communities, environment and rural affairs. Officials from the Health and Safety Executive also work there. Construction began in the early 1960s.

Consultants determined that flood risks to and from the site have been addressed. Designs incorporate flood proofing. Local development plan rules permit such work in the area under specific conditions.

The site has flooded before, including a significant event in 1969 and smaller incidents in later years. Flood defences were built locally after heavy rain damaged the Campsie area in 1987.

Plans for the site contrast with nearby former Scott's Mills, ruled out for retail development due to flood vulnerability.
