FOI003378 FOI Enforcement and Parks

I am seeking information about no ball games signage.

No ball games signage is found in a range of settings, often parks, verges and council estates. 

I would like to know:

1. How many “no ball games”, “ball games prohibited” or similarly phrased signs has the council purchased in each of the past 10 years;
2. How much the council spent in total on the items purchased in (1);
3. How many “no ball games”, “ball games prohibited” or similarly phrased signs are currently maintained by the council, if such a record exists;
4. What the council's policy is on erecting "no ball games", "ball games prohibited" or similarly phrased signs, if such a policy exists.
