How did we get here?

The Office of Public Works (OPW) was requested by Mayo County Council (MCC) to address the flooding problem in Crossmolina, which resulted in the OPW Design Section undertaking a feasibility study that involved a preliminary investigation of the problem. This pre-feasibility study showed that a flood relief scheme was technically possible and economically viable. Subsequently, Ryan Hanley Consultants were appointed as consulting engineers and an initial options assessment report was prepared by Ryan Hanley consultants in November 2013.

The original preferred scheme included a walled solution through Crossmolina town, and a public information day was held for this option. At this stage, only preliminary investigations had taken place, and once more detailed investigations took place, it became apparent that the Jack Garret Bridge in Crossmolina Town was structurally unstable, and would need to be replaced if it was to be incorporated into flood defences. In addition to this, the people of Crossmolina advised that they would prefer an alternative to a walled solution if one was available. 

As a result, other potential options were explored and assessed, and a new preferred option was identified. This option includes a diversion channel, which will intercept excess flood waters prior to it reaching the town, and divert the water directly into Lough Conn, where the River Deel ultimately empties.

The formal Public Exhibition was held in May/June 2018, with a total of over 100 attendees over this period, along with 10 written submissions. Following consideration of all submissions, it was deemed that no significant changes were required to the scheme.

Following on from Public Exhibition, the detailed design and relevant environmental assessments were completed, and the scheme documentation was finalised and submitted to the Minister for Public Expenditure and Reform for Confirmation in Q3 2020.
