Overview and History

The City owns about 140 miles of stormwater pipe. Most of these pipes are over 50 years old and have exceeded their expected lifespan. Older pipes can become damaged over time. Damaged pipes can cause serious problems such as flooding or sinkholes. In 2011, we started a program to inspect all pipes by video camera to identify damage.

The Stormwater Pipe Repair and Replacement Program (SWPRRP) fixes damaged pipes. We prioritize repairs based on the severity of damage and importance of the pipe. Our preferred repair method is to install a durable liner inside the existing pipe. Pipes too badly damaged to repair by lining are dug up and replaced. We seek to maximize the number of repairs we can do by choosing the lowest-cost reliable methods.

2025 Stormwater Pipe Repair and Small Drainage Projects

The 2025 Stormwater Pipe Repair and Small Drainage Projects will be a combined project part of the City’s ongoing multi-year SWPRRP and Surface Water Small Drainage Projects Program (SWSDPP). These programs proactively ensure public safety reduce flooding, decrease maintenance demands, and protect critical infrastructure and other public and private property.

This project will repair or replace short segments of damaged stormwater pipe at multiple locations throughout the City. Construction activities will include any or all of the following, as needed to complete repairs: Pavement removal, excavation, pipe repair or replacement, pavement repair and temporary traffic control. In some cases, a new catch basin may be installed to help facilitate better surface water drainage.
