What about the 3,500 homes that are in for Planning just to the south of the City in North Kesteven between Bracebridge Heath and Canwick filling in all the the land between the top of the South Common and the new Eastern Bypass. Not much danger of flooding up there and while technically not in the City nether is North Hykeham but it gets counted as one conurbation. What about the 1,000 plus homes being built between the edge of the city and the bypass to the North of the City in West Lindsey but still joined to the City. How about all the new housing estates being built in Branston, Waddington, Washingborough etc while not in the City not far away.
How much additional housing stock do we need in the next 15 years?
While you say the City have a target these targets are being met by land being developed around it and these can be set against the limitations of land available within it with offset.
I know where I would rather live and it certainly isn't Swanpool? What people also tend to forget is that insurance is rising rapidly for properties in Flood Zones and while they might be able to come up with a technical solution now I bet your bottom dollar the Flood Zones will only get bigger not smaller. My friend sold his house in the Lincoln Flood Zone because his insurance costs had trebled in the last few years and he could see where it was heading. Properties in Flood Zones will be worth less the mortgages in these areas are already more expensive and less choice.
