An appeal has been lodged with An Bord Pleanala against plans for a major residential development in Letterkenny.
Blake Burke Limited had been given conditional approval by the council for the development of in excess of 300 houses in the Oldtown area.
However that decision was appealed by a local residents group.
The council awarded permission for the development in the Scribbly area.
It entails the demolition of existing agricultural buildings and the erection of 310 residential units, comprised of a mix of attached, detached and semi detached houses as well as apartments.
The plans also include the temporary water treatment plant, car parking spaces, a bus stop and a pedestrian bridge over the River Swilly.
The development has been objected to by the Cullion Road Residents Group.
They contest that it would effect their water supply, current sewage works locally could not sustain the development.
There is also concerns that this would be a 'bubble' development and that the land is suitable for agricultural use only.
The appeal is being considered by An Bord Pleanala with a decision due by the end of September
