Pavement dip creates obstacle

Hi, there is a dip in the pavement outside 155 Boldmere Road right by the pedestrian crossing used by parents and pupils walking to Boldmere School. When it rains this creates a puddle which parents and children have to go around to get to the pedestrian crossing. If there is a car on the drive at no. 155, people have to squeeze around it, go through the puddle or go into the road which is not ideal. This is especially a problem if you have a pushchair
