The council has kindly put double yellow lines outside my house leaving us with no parking at all! There is some spaces down the street inbetween peoples driveways but only gives you two hours and thats when you can find one not already ocupied. So i get a letter a couple of weeks later saying that they are going to do some work on the pavement, and would we like to have a drop kerb installed. I have decided to go ahead with it. I just need to know how thick should the concrete be in the front garden to be able to support the weight of my car?
