Members expressed concerns regarding the proximity of the proposed development to the ponds below the site.  It was agreed that an amendment to the landscaping condition 13 be included to specify some form of fencing was erected to close off the ponds from the residential development area. Members also requested an amendment to condition 13 of the report to clarify that the required landscape management plan related to the application site as a whole which included the ponds. 

Members discussed the possibility of installing electric charging points in the parking area.  Officers confirmed that the Authority was not able to insist on but would discuss with the developer, but it was noted the capacity of the existing power supply could make this unviable.  It was noted the provision of charging points was not included within current policy but it was a possibility in the future.


Members thanked officers for the work with the applicant to amend the original application.


The Officer recommendation to approve the application subject to changes to the conditions was moved and seconded, put to the vote and carried.
