Crab apples everywhere

we have a lovely blossoming tree in spring but the apples fall everywhere in the communal ground of the development and cost a lot to clear up. They also fall onto cars and mark them and  are slippy on footpaths. Is there a means of cutting off the blossom when it has died away thereby preventing the apples from developing? if we did this would it still blossom in the future years?? Could we reduce 75% of the blossom thereby ensuring it would blossom each year? Thank you Judi
