I seem to recall being invited to engage in a similar consultation a few years ago and the papers were hand delivered to the properties around us - all five days after the closure date for submissions.
This process seems to repeat that cycle of consultation in a very short cycle.
The current version is long - and does seem pre-disposed to the adoption of CPZ's. Unfortunately after having completed mine online the LBL system crashed and did not issue a confirmation of receipt. I await a response from them advising if the submission was processed or not.
The implementation of CPZ's are the very thin edge of a long wedge. I believe they are appropriate in only very limited and specific circumstances and then only where on-street parking becomes precious in areas adjacent to rail stations where improved services induce commuters to park-and-ride at that station.
Anecdotal tales of horrendous problems in other London boroughs with overly complex processes of acquiring permits and visitor permits are common and once implemented, LA's find it difficult to resist the escalation of prices or increasing the footprint of CPZ's as they become dependent on the income stream.
