Pueblo Alto Mile Hi Green Stormwater Infrastructure

Background and Goals

The primary focus of this project is to reduce flooding and drainage problems south of Constitution Ave to Lomas Blvd, between San Pedro Dr and Washington St.

Existing underground stormwater drainage infrastructure no longer has the capacity to withstand larger storm events, specifically 100-year storms. Smaller, neighborhood-level, green stormwater interventions will be implemented to mitigate local drainage issues, while the larger drainage projects are being planned and implemented.

Construction has started on this, the City's first neighborhood-scale Green Stormwater Infrastructure, (GSI) project.

The Pueblo Alto neighborhood will soon be transformed with new features that won’t just calm traffic, but soak up stormwater, cut flooding, and add a fresh burst of greenery to local streets.

In the Mile Hi neighborhood, crews will be adding underground water storage tanks. These tanks remove water faster from the street level and drain in 24 to 48 hours. They are easier to clean and maintain, keep streets cleaner, and drain faster than the current system.

The overall cost of the project is about $6.5 million, and construction should be complete by the beginning of the 2026 monsoon season. 

GSI has been successfully implemented in other locations nationwide and offers numerous benefits:
•    Filters stormwater before it enters arroyos and the aquifer.
•    Reduces sewer overflows and keeps stormwater out of the system.
•    Minimizes flooding.
•    Adds greenery.
•    Reduces standing water and related mosquito hatches.
•    Calms traffic via curb extensions.
•    Quickly stores stormwater underground.
