Sierra Drive Stormwater Improvement Project

Stormwater System Upgrade

We are replacing a storm drainage pipe and culvert on Sierra Drive and Balboa Road to reduce flooding and erosion. The project will be performed in two phases in order to minimize disruptions to the neighborhood traffic. Phase I will be limited to the downstream improvements and Phase II will consist of the upstream improvements.

Construction

Balboa Road and Lawrence Drive intersection is closed through early-fall 2023!

Phase I of construction has begun and will be completed in approximately 8 months. The intersection of Balboa Road and Lawrence Drive is closed and both roads are closed to thru traffic. Local traffic can use the detour on Sierra Drive and Saturn Street.

For additional guidance, you can read the Traffic Control Details Map for the project.

Background

The stormwater system on Sierra Drive includes open channels (streams) and pipes. The pipes drain to Balboa Road toward Lawrence Drive. Eventually, the system leads to pipes underneath I-40. We need to update the system so that the area doesn't flood.

The Study

The preliminary study was done in three phases:

  • Looking at the condition;
  • Determining alternatives; and,
  • Working on the preliminary plan. 

The goal is to study, analyze, and implement project(s) to alleviate structure/public street flooding and erosion.
