Hi Sandra,
Thanks for your kind comments.
You're right about the continuity issues, it's tough when they chop and change points of contact, and I guess this is where the process needs to be more rigid. If the process is clear, and you stick to the communication protocol it shouldn't matter (at least in theory!) if the planners are interchanged along the way.
Municipal town planners can tend to talk in abstracts – like mass, density and scale – so you're approach of trying to quantify the requirements is, in my opinion, the right approach.
And, should you do it all again, we would look forward to the opportunity of working with you!
Christian.
