The CRR is a prescribed authority under the Planning and Developments Regulations 2006. As such notice must be sent to the CRR
“where the development might –
- give rise to a significant increase in the volume or type of traffic (including construction traffic) passing under a height restricted bridge or using a railway level crossing, or a bridge over the railway,
- because of its proximity to a railway, impact on the structural integrity of railway infrastructure during construction of the development, or
- endanger or interfere with safe operation of a railway during or after construction.”
In the case of a development which might impact on a light railway (e.g. the LUAS) or a metro, Transport Infrastructure Ireland (TII) should be notified.
