If you would like a Street Park in your area, the best thing to do is ask your councillors. The borough is divided into wards and each ward has three councillors. It’s their job to listen to residents and make decisions on our behalf. So send them an email now.
In the longer term, a great thing to do is join Living Streets. This campaigns for better streets for walking throughout the country. It is free to join, and the local group will keep you informed about what is going on in Ealing.
