Good ideas from somewhere else: Rain Gardens.

Kansas City has a great new idea to mix the need for sustainable urban drainage with citizen participation for minimal effort: 10,000 Rain Gardens. Basically, it aims to get residents to create 'rain gardens' that hold stormwater - as small as a few square metres - and help the massive problems of drainage that the city has.

Easy - and made even easier by the website which has easy how-to guides on making one, equipment suppliers if you want to install a rainwater butt or buy native plants, and a list of professionals who can make one for you if you don't have the time: alongside workshops, festivals, and a picture gallery of completed projects.

I bet the whole scheme costs nothing - the price of a few metres of municipal stormwater drain installation in a busy road. I'd like to see every city have a scheme like this.
