City considers expanding central storm water project

The Glencoe City Council heard a supplemental feasibility report for the 2018 Central Storm Sewer project from Justin Black of Short Elliott Hendrickson, Inc. (SEH), at its Monday night meeting.
After Black’s presentation, the City Council passed a resolution to hold a public hearing on Monday, Nov. 20, at 7:15 p.m., for the added improvements and properties to the Central Storm Sewer project.
Since the original feasibility report for the Central Storm Sewer project was given on Dec. 19, 2016, a number of revisions have been made because of additional design review, city staff feedback and comments from the community.
“Overall, the project footprint is expanding,” said Black. “One of the directions we received going forward with the design was to see if we could extend the larger pipe further north and we were able to achieve that, but that came with a cost and also having to relocate some utilities.”
Proposed revisions include increased storm sewer size and revised alignment, additional sanitary sewer replacement, realignment and cured-in-place-pipe lining (CIPP), additional water main replacement and new water main construction, as well as additional street reconstruction.
The proposed storm sewer system will be constructed of larger diameter pipe. For example, from Ninth Street to 13th Street, a 60-inch pipe will replace 36- and 48-inch pipes; from 13th Street to 15th Street, a 54-inch pipe will replace a 36-inch pipe; and from 15th Street to 16th Street, a 48-inch pipe will replace a 30-inch pipe.
The 48-inch storm sewer pipe will end at the intersection of 16th Street and Louden Avenue and an existing 30-inch pipe from the north and an existing 18-inch pipe from the east will connect with the 48-inch pipe.
Black acknowledged that a lot of work and precision will have to go into making sure these larger storm sewer pipes fit within the existing space. “It does impact some of these other utilities,” said Black.
