Unimproved Alley Paving Program

Because of ecological impact of unpaved alleys and the economic drain of maintaining them, in 2005 Mayor Hickenlooper created a program to pave with asphalt the more than 1000 unimproved public alleys in the City. The program took approximately 6 years to complete with 100 to 200 alleys being paved each year.

Alley Types and Maintenance

There are four kinds of alleys in Denver, and each is maintained differently.

Asphalt Overlaid Alleys
