Annual Small Drainage Program
This program fixes small public drainage issues that often start as customer service requests or issues we find in the field. For greater efficiency, these projects are batched together. Solutions typically entail installing catch basins, pipes, berms, and other small improvements within the public right-of-way. This program is funded by Surface Water Utility Fund which collects fees from all City residential and commercial properties based on the amount of hard surface/impervious area on the developed properties. These projects proactively ensure public safety, reduces flooding, decreases maintenance demands, and protect critical infrastructure.
This year’s project will extend storm drainpipe and catch basins to reduce localized flooding on the street’s listed below. The project was awarded to Titan Earthwork. They will mobilize on July 25th and are expected to complete work by September 20th.
