Resolution setting a public hearing for September 12, 2022 at 7:00 p.m. for the N. 28th Street Storm Sewer Rehab, Phase III.  Project # PW23-11 

The drainage basin limits for the N. 28th Street storm sewer are approximately I-29 to Avenue F, and N. 10th Street to N. 33rd Street.  This area is roughly 580 acres.  The existing storm sewer network in this area was constructed in the 1950’s and is undersized causing frequent street flooding. The existing storm sewer interceptors are located along Avenue L, North 24th Street, and Avenue K.  In recent years, the unusually high ground water conditions have caused several of the storm interceptors to fail, resulting in costly emergency repairs.

Phase I is complete and included construction of a new 84” storm sewer pipe under I-29. The Phase II project included an engineering study phase to identify and prioritize future projects within the drainage basin and construction of a new 84” storm sewer from the pump station to the north end of the 84” under I-29. 

The Phase III project will connect a new 84” storm sewer to the south end of the existing 84” storm sewer under the interstate and extend the storm sewer into N. 28th Street connecting it to an existing 60” storm sewer.  This will allow for additional pipe capacity to the pump station. 

The project was included in the FY23 CIP with sales tax funds.  The project budget is $2,000,000.

Approval of this resolution. This project will provide connection of a large storm sewer to the pump station, providing future added capacity for the N. 28th Street drainage basin.
