Porter County manager: Rolling Meadow storm-sewer replacement underway; full program to take several years
Summary
The county’s program manager reported that phase one of the Rolling Meadow storm-sewer replacement (P26-024) started in early May, will install a 30-inch concrete storm sewer and a 72-inch manhole, and that the multi-phase program could take five to seven years to complete across the subdivision.
Porter County’s program manager updated the board on P26-024, the Rolling Meadow subdivision storm-sewer replacement project, saying construction began in early May and phase one will replace undersized pipes with a 30-inch concrete storm sewer and 12-inch laterals in finger streets.
"This is the limits of the storm sewer replacement... that manhole that you see there, that is a 72-inch manhole," the program manager said, noting the contractor is Gary Construction and Burke Engineering is providing construction observation and design services. The project area is between Aberdine and Shorewood Forest subdivision, just off County Road 325 West and south of County Road 100 North.
The manager said the phase-one work focuses on a master outlet and 30-inch trunk that should provide a positive outlet for future master tile reconstruction and reduce rear-yard flooding and septic backups. The manager estimated the full program of phased master-tile reconstructions across streets would likely take "five to seven years," adding that some residents may see relief as master tiles are connected to the new trunk.
Construction details discussed included bedding and backfill specifications, a stone envelope around the pipe to increase service life, and plans to abandon smaller existing storm sewers in place by grouting. The manager said the 30-inch trunk is intended to be long-lived (industry estimates referenced as "50 years" for service life), and said the county is coordinating with the highway department so the county’s storm portion is paved to intermediate course before the highway department resurfaces remaining sections, which saves stormwater fund dollars.
Board members asked about sequencing and when residents might see relief; the program manager said relief would come when the new master tile is constructed and noted the county will add stubs to the new sewer to allow future master-tile connections. The program manager closed by saying work has progressed well so far and by thanking the contractor and engineers on site.
The board set its next meeting for July 13 and adjourned.
