I'm looking for the same information. What
city are you thinking of and what are some obvious regional issues that this idea could be intended to fix.
There is the National Green Infrastructure certification program in the US, that recently went national, so you could get an official certification for building "green infrastructure" which includes a lot of
permaculture concepts for watershed and storm
runoff management. Www.NGICP.org I believe.
I'm in Pittsburgh and the
local bureaucrats are dragging their feet on setting the training program up here, otherwise I would have it.
Government agencies that manage infrastructure and environmental problems would be good to talk to. Roads, pollution sources, flooding problems,
water lines and sewage infrastructure will all greatly benefit from regional
permaculture projects with properly planned watershed management.
