Right of Way Acquisition

We completed the design for this project and are now in the pre-construction phase. We have: 

  • Routed and finalized the construction contract; and, 
  • Received required permits and easement acquisitions for the project. 

There have been a few delays related to material availability. Construction is now expected to start in the spring and last about eight months.

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.
