Overgrown patch of nettles, orchard recreation park

There is a huge clump of nettles and brambles in the park (next to 10 croft avenue) which needs cutting back. I live close by and it used to be cut regularly when they cut the grass in the park.. People throw their litter, beer cans and bottles in it. Children lose their balls in it and get stung by the nettles. The whole area has got bigger and the nettles have got taller over the last year and it looks unsightly. It needs cutting back to the fence and then cut regularly when the grass is cut.
