25th Street and Illini Storm Drain Improvements

Hoskin Ryan was contracted to study and design a storm drain system that would alleviate flooding in an older established neighborhood in the City of Phoenix. The neighborhood did not have an existing storm drain system, causing extensive ponding and flooding. Hoskin Ryan surveyed, developed base maps and completed the storm drain design. Due to our thorough analysis, the project was extended further up one of the streets as we identified areas where the runoff was leaving the street and flowing through the properties rather than continuing towards the sump as initially assumed. The selected design alternative included a new storm drain design that provided specific drainage relief for the local residents.
