I went to visit a friend not so far from Brockley and came across a parking solution that may represent an acceptable solution for Foxberry road and other roads around the station. I never saw this before and thought I would share it.
The picture shows a parking restriction 9 to 6.30 with the possibility to park for up to 2 hours for free multiple, non-consecutive (ie: max of 2 every 3 hours), times a day.
This does not solve the cost of £150 per year, but would give a very intellingent answer to all comments such as "I do not want to pay if the plumber, a friend or my mother comes to visit me." Or "I need to be able to park near the high street when I go there with my children to buy food."
