Your Waverley Park Experience

I'd like to reduce the speed of cars on Ravenswood without moving the problem somewhere else in WP and still allowing residents access for their cars. The only way to reduce cars is to close the roads at Durwood and Dinmont so WP is not a through route. This was proposed and previously rejected, one of the reasons being it would be difficult to get cars out on an icy days with steep hills to negotiate. I think the lanes are the obvious space for more play areas, community areas etc but they are owned by the residents so everyone would have to agree and there would still have to be access for emergency vehicles and cars. Would synthetic grass on part be an option ?
