Have you considered the perspective of your councillor who is probably not as clued in to the issues as you?
How many emails (and other communications) do they get every day?
How many communications are relevant to their responsibilities and abilities to influence?
I'd bet that an elected representative who depends on votes to stay in a job likes nothing better than an issue presented simply, well and clearly with the obvious solution(s) outlined.
There's a psychological 'trick' that suggests if you want someone to do something 'big' for you you're better off asking for something small and inconsequential first. That first 'yes' makes a subsequent 'no' more difficult to deliver.
Or in layperson's term, start small finish big.
I'm not a stranger to local Government. At least not the political end. I did stand as a Councillor and knocked on every door in the ward. Some correspondence was received. The majority of it was hate mail. And I did a lot of work with elected Councillors.
Honestly, I expect my email to be ignored because I am a minority voice. There maybe 2 or 3 other people across the Council's area that share the same concerns.
My faint hope is that the email is read and perhaps the Councillor will forward it to their colleague who has the transport brief, who will read it. I would they have a deeper understanding of what is needed to support cycling. And then hopefully, armed with knowledge of the issues raised, will recognise future schemes that will, without amendment, be dogged by the same problems.
It is sadly not a simple problem, with a simple solution. Those ultimately responsible for the cycling infrastructure are not cyclists. The root cause is a lack of knowledge and a lack of understanding. Which is why I ended the missive with a suggestion that Councillors should attempt to conduct their civic duties for a week or for a few days without relying on a motor vehicle, instead walking, cycling and using public transport.
Besides, I'm confused. I fail to see how inadequate bike parking leads to complaints about flood plains.
It was the last straw. A trigger. Something that caused me so much inconvenience and aggravation, that I started to act. For future developments, that's for correspondence with the other council, in respect of their local plan for new developments. And for existing developments, that's a letter to the business owner or, if applicable, the landlord.
