QUESTION NO. 10

QUESTION: Councillor B. Leech

To ask the Chief Executive what would the approx. costing of culverting the Whitestown Stream between the Cloonmore Road and the N81 to build a linear community park enhanced with border hedge, trees and seating arrangement?

REPLY:

As this area has previously been prone to flooding and works have been carried out here in this regard, culverting this section of the stream could raise the flood risk. A Section 50 approval would also be required from the OPW. The European environmental trend is to keep waterways open and to re-open enclosed waterways where possible. With regard to the flooding and Environmental reasons above we would not recommend capping/culverting the Whitestown Stream. 

An accurate cost for any culverting work would require design of the solution required. Culverts also require Section 50 approval from the OPW. Section 50 approvals assess proposed works to waterbodies from a flooding impact point of view.

Without a proposed design for a culvert it is difficult to estimate a cost. A very rough estimate for a culvert would be in the region of €400,000.

Works on the development of a park would be an extra cost above this and would vary considerably depending on the quantity of earth moving and hard landscape required.
