Take a look at the Blueprint website: http://valleyblueprint.org/index.html
It almost goes without saying that population growth and how that growth is facilitated will have a huge impact on our environment. The Blueprint is an effort to guide regional land use and transportation planning until 2050 and beyond. Take a look and provide your input in favor orfhigher density, more environmentally friendly, more farmland friendly growth.
There is also a public summit next Monday that I will be attending. I encourage people to attend if they are able. The registration is $35 and more info can be found at the website.
