Before MORE house are built I think the Council should carryout a comprehensive study of existing housing as to the current usage and occupancy. Some larger houses could become available if those larger houses were of single occupancy as elderly people move to a flat or bungalow. There are also houses that are unoccupied and appear abandoned by the owner.
Your own document talks about making effective use of existing infrastructure, facilities and services.
Any new housing that is found to be needed must contain a lot more 'affordable housing' than stated in current policy; and affordable must mean affordable to local residents with regard to local wages and general employment expectations in the Chichester area. During a new planning application for any new development, conditions can be put into place to ensure this happens.

I also feel the current infrastructure needs also to be improved. As you are already aware the A27 is already at saturation point every morning and afternoon and most of the daytime during the summer period being the main trunk route East to West to the Channel Ports and holiday destinations in the West Country. This is a good opportunity to consider sympathetically upgrading the existing route before building another road through our local countryside. I also understand that although improvements are on going to the foul sewer system this is designed only to cope with the new housing already approved. No further capacity has been allowed for for the additional housing proposed in this Local Plan Review
