I was wondering if anyone has had an experience, policies, design, etc. on implementing "green streets" as a part of a new development project. My firm is currently working on a specific plan where we are going to take the lead and implement "greener" principals such as requiring percentage of homes to be certified energy-star efficient (a must for a proposed LEED ND project), reducing street paved widths for reduce heat island effect, providing walking trails that connect to commercial, schools, parks etc. but what i really want to implement is a green street that reduces urban run-off through either a bio-swale contained in a bulb-out or planting strip, or other means. I am using Portland's green streets as a model to how to design these things, but it is tough since California doesn't see as much rain as Portland, so i don't know how efficient this will work. Any thoughts or insights will be greatly appreciated. Thanks.
