Everybody meets infrastructure upgrade costs through council tax and utility bills. New houses can't be blamed for existing problem. A new house owner would pay council tax so will contribute to maintenance which would have had to be undertaken anyway.
And in reference to planning the issue is not considered a material issue so holds no weight in the decision making process anyway.
It is not considered - but it should be! The small amount of council tax and utility bills generated by these houses will not cover the infrastructure costs if major upgrades are required, but the council is supposed to do it anyway, even if they'll never make their money back in any realistic timescale. And yet the developers make millions.
As an example, the Poynton Relief Road is built and funded by the council to facilitate development. It will cost about £30 million (20,000 average council taxes) and probably about £150k per year (100+ average council taxes) on average to maintain properly. Obviously only a small part of your council tax goes on roads - in Cheshire East about 5%. We all know it is not enough, but even if it is was it will still take the road budget for at least 2000 homes every year just to maintain it - that one small road. Obviously that ignores the initial build costs, which are 3 times the entire annual Cheshire East road budget
. Councils are not allowed to put up tax so you'll need at least 2000 new houses to cover the cost of maintenance - probably a lot more. We are only getting 650 houses in Poynton. Most people would think that is far too many, but it won't cover even 2-miles of A-road. Which is why our roads are crumbling.
The same applies to all the services and utilities. It will be more expensive to supply ambulance services to rural areas for instance - so the last thing a stretched NHS needs is more houses in hard-to-reach areas.
If the developers were forced to make a proper contribution for the costs then they'd be less keen to build in remote places, and more keen to redevelop existing places. They just have the cost of a field or garden, the rest of us have generations of costs to clear up after them.
