Waterlily2000 I once tried to work out the size of the car-parks which you think schools should have.
It only works if parents are sure they will find a space and be able to get in and out quickly and easily – if not, they will ignore the car-park and stop outside the gates. So there must be as many spaces as likely users, wide access and egress aisles (no queueing to get in or out), wide visibility splays, and new lanes on the roads outside to allow cars to leave and join safely. No charges, of course, because that would take time.
It may be possible to use them at weekends or during the holidays to recoup some of the money invested in them; but they will have to be locked during the school day or at evening pick up time parents may find that others have parked there. In fact they will have to be locked during the night or commuters may get in before the parents do. Everyone arriving will need some sort of badge for the window.
And how many spaces? Take a primary school, three entrance classes, children there for six years, 450 children. Some no doubt siblings – but others will be singletons as regards that school but have one or more siblings in other schools and therefore the car will use two places every morning and afternoon. Allow for some parents who will not use it in any event. A fair guess is 400 places.
Research at my local shopping centre suggests that spaces will need to be five by three metres; that makes 6,000 square metres just for the bays. Add a quarter (and that is modest) for the wide aisles and access/egress routes and you get 7500 square metres.
Which is about a third as big again as a professional football pitch.
Secondary schools tend to be even bigger, but may have fewer children driven to school – although if the car park is there the not-so-little darlings may expect a lift there too.
These are ball-park figures but they are in the right ball-park, and if anybody thinks providing car-parks at school is realistic, I can offer you some shares in the New Atlantic Bridge Company, and they must be all right because they are underwritten by Lehmans and Barings!
