State of the green roof movement in North America

In light of recent discussions in Toronto and Montreal, I thought that we could take a look at the state of the green roof movement around the world, starting with North America. In about a year we'll take a look at the list again to see what has changed. 

My rating system:

*** = green roof guru

** = green roof supporter

* = green roof newbie

Feel free to let me know your thoughts!

Austin - 

In the Southern United States Austin has been a true green roof pioneer. Starting with a white paper jointly produced by their water protection, conservation and planning departments in 2007, they have experienced slow, but constant growth. Incentives are offered in Austin for the installation of green roofs, however not in the form of direct grants. They still have three more years left in their implementation plan, so I would say the future looks bright in Austin. Although their current mayor is up for re-election. And we all know how important political support for your cause is.

Chattanooga -

Talk about late breaking news, on Monday came the first signs they will begin offering credits to developers.

*
Chicago - 

What can you say about Chicago? It's green roof cred is rock solid. In 2001 Mayor Daley jumps in, sedums a' blazin', and they haven't looked back.

Don’t get me wrong, it would be great if they still gave cash incentives, let’’s hope they do with Rahm Emmanuel at the helm. Ahhm...Rahm?

**1/2

DC -

Get your cash!!! One of the latest big cities to join the party, they offer a very generous $5/square foot, up from $3. Let’s hope in 3 years time it jumps to $8. We can hope, can’t we?

**1/2

Louisville - 

We've got some good signs coming from Louisville. Last fall incentives for developers were agreed to, which is a great start.

*

Milwaukee -

Since 2003 Milwaukee has steadily increased support for green roof (and of course, urban agriculture). Tom Barrett is your man with a plan, but with his entry into the gubernatorial race, if he wins, what happens in Milwaukee?

**

Minneapolis -

Add a green roof and you can receive up to a 50 percent credit (aka reduction) in your stormwater utility fee. Sweet!

**

New York City -

After a comparatively slow start, New York City has gotten serious about green roofs and green infrastructure quickly. A comprehensive green infrastructure plan and $187 million dollars over the next three years with perhaps $2 billion more over 20 years speaks volumes.

The green roof tax abatement is up for renewal this year, but I feel good about its extension considering the city is building “green” playgrounds now and the mayor put a green roof on his foundation. 

***

Philadelphia - 

In 2010 Philadelphia began offering a tax credit for businesses willing to install a green roof, great move!

**

Portland - 

The city is synonymous with green and for good measure. Their program started in 2008 and has been going strong since, installing over 100,000 square feet in 2011 alone! 

**1/2

Seattle -

It appears Seattle had an incentive program back in 2007. Then in 2009 changes were made to Seattle's building code opening the door for developers to get credit for installing green roofs. Then the green roof momentum slowed. Not sure what is happening now. 

*1/2

And last but not least, one small but committed municipality...a 30-45 minute drive from the centre of Vancouver, Port Coquitlam has it’s very own green roof bylaw.
