Ada County Highway District

2018 Green Stormwater Implementation Project

Construction update as of 11/02/18:  The alley between 8th and 9th is complete. The pavers for the alley between 4th/5th are complete. The alley is open and there remains some minor work that will be complete by the end of next week.  

General Description:
Starting in early June, the Ada County Highway District will retrofit the following alleys in Downtown Boise with permeable pavers:

  • The alley between 4th and 5th streets north of Main Street
  • The alley between 8th and 9th streets north of Fulton Street

Permeable pavers help eliminate standing water and clean the rain and snow melt. The result is less polluted runoff returning to the Boise River.

The Capital City Development Corporation (CCDC) will provide hardscape enhancements for the alley between 8th and 9th streets. Utility work and replacements will also be included in the project. 


Time Frame

Start Date:  June 2018
End Date:  September 2018
