A few recommendations / ideas

More trees and flowers along the entire street Hwy 66 down to 3rd would be nice. 

Buttons at crosswalks that make the intersection flash when a pedestrian is there, as they have in Boulder.

Extending artwork from south bridge up North through downtown and as far as 17th would be amazing!  Love all the art fair stuff that happens in Longmont so it would be in character.

Turning parking lots all over town into covered lots that are also solar farms would be amazing!  Would generate electricity while shielding the sun, and more of those Tesla batteries to store it!   Electric charging stations for ev's...  What about putting some of those solar paths in like they have in the Netherlands, along the river?  Might also be beautiful downtown on Main street.

Underpasses for pedestrians across main in a couple places, that connects bike and walking paths...
