Resolution authorizing the Mayor and City Clerk to execute an agreement with HGM Associates Inc. for engineering services in connection with the N. 28th Street Storm Sewer Rehab, Phase IV. Project #PW24-11

The N. 28th Street drainage basin limits 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 the past, high ground water conditions have caused several of the storm interceptors to fail, resulting in costly emergency repairs.

Phase I is complete and consisted of construction of a new 84” storm sewer pipe under I-29. The Phase II project is complete and included the study of the drainage basin to identify and prioritize future projects and connected the 84” storm sewer to the N. 28th Street storm sewer pump station. Phase III is currently under construction and includes the extension of the 84” storm sewer from south of the interstate to N. 28th Street.  

Phase IV will include the replacement of the storm sewer interceptor in Avenue L from 27th to 28th Street. The project will require the reconstruction of the roadways and sanitary sewer.  The phased approach of this rehabilitation project is based on prioritizing the roadways with existing storm sewer interceptors, frequent flooding areas, and infrastructure that is in poor condition needing immediate replacement.  

The Engineer was selected based on their previous involvement with phases I thru III and their successful project history.  HGM helped to develop the overall plan and phasing strategy for the area, and it is fully expected that the knowledge already gained during Phases I thru III will benefit the current project.  It is appropriate for HGM to continue their role as project engineer.

The project was included in the FY24 CIP with funding from Local Option Sales Tax and Sewer Funds.  The preliminary project budget is $4,000,000.

Approval of this resolution to select HGM Associates Inc. to continue their role as project engineers for design and construction engineering services associated with Phase IV.
