Green Alley Project

The Green Alley Project is a public alley north of Foothill Boulevard between Alta Canyada Road and Indiana Avenue (behind Armstrong Garden Center, 7-Eleven, and La Cañada Imports), where pavement is currently in a failed condition and requires full reconstruction. As an alternative to conventional asphalt pavement reconstruction, the situation presents itself with an opportunity for a project that provides stormwater quality and MS4 Permit compliance benefits along with public space beautification, business frontage enhancement, and pedestrian place making.

A project concept known as a “green alley” is proposed for this location that would involve installation of a permeable pavement over an infiltration gravel bed. The outer edges of the alley can accommodate narrow planting beds for low-profile or climbing plants to green the space. Adjoining alley walls can be painted with artwork subject to City approval and permission of the wall owners. The project is scheduled to be constructed in FY 2020/21.
