Go onto the council website and challenge as follows:
Dear London Borough of Redbridge,
I require you to consider my informal representations as my formal representations.
Yours faithfully,
Draft representation:
Dear London Borough of Redbridge,
Footway parking is allowed on the entirety of Greenleafe Drive, please see the documents at link1 and link2.
In light of the above, the penalty charge notice must be cancelled.
Yours faithfully,
The links in question will point to https://drive.google.com/uc?id=1BxppUfdcrUYelGCDh0tHUZdkjNW6lgru and https://drive.google.com/uc?id=1xNESNzkLQ1oPEG78bK9ksWZSEBlsVQBk but do not put these links in the representation, use the ones I'll send you via private message.
The reason for this is that we can check the click count and if it remains at zero, we can prove they've not looked at the documents and that is a failure to consider, which is a procedural impropriety.
For that reason, please do not click on the links in my PM or you'll sabotage the plan.
