If you know which day the contractor is removing the doors, just arrange for council to pick up as soon as possible after. If the EC won’t do that – have no idea why a simple phone call to council would be a hassle – then one of the residents can do so.
Have no idea who is responsible, but it doesn’t sound like a huge problem to solve. You may wind up with a big pile of doors on the nature strip temporarily – which may disappear before the council get to pick them up.
