While the RA zoning is "subject to the provision of the necessary social and physical infrastructure" I am not convinced that the infrastructure will be built before the residential buildings. If that were to happen we would be back to the usual cycle of social and physical infrastructure catching up with the needs of residents.
Looking at school provision, something that is consistently delivered late, this results in children in an area having to travel out of their immediate area for school. Most of this travel is done by motor vehicle. Sibling rules in schools means that entire families are driven to these distant schools. This all increases congestion, carbon emissions and reduces physical activity and active travel - the exact opposite of what we should be aiming for.
So, either undo the RA zoning of the Dunsink area or stringently enforce the provision of the necessary social and physical infrastructure before residential building commences - like was mostly done in Hansfield SDZ.
Also, the loss of Elm Green golf course with a pitch and putt course and a driving range, one of the few public golf course, would be a very negative thing.
