This is a large development for this area. So I would expect the following:
All the houses need to be affordable and in keeping with the village structure ie along The Street and not behind it. Improvements to infrastructure required as part of plans - such as water & electrical supply to accommodate additional load on system. Note existing black outs and low water pressure issues.
Plans to improve travel links through the village and the link to Norwich for bikes, cars and pedestrians. The main link road is already busy and realistically Norwich is likely the main employment and services hub for this development so an increase in motor vehicle traffic is inevitable. Also note these roads are already becoming increasingly risky for walkers and cyclists with increasing traffic.
Long term as well as short term assessments of the impact on the local habitat/environment - especially where it is likely increasing the load on an already overloaded Broad ie Rockland Broad & Surlingham Broad.
Impact assessment on flooding from additional run-off with realistic practical long term methods of mitigation.
