La Porte board approves modeling assessment and short-term measures to target chronic combined-sewer problems
Summary
The board accepted a proposal to model chronic combined-sewer drainage in the Lawrence/East Jefferson area, approved a basement-backup grant for 601 Lincoln Way, authorized appraisals on parcels adjacent to the treatment plant, and asked staff to review underground tank replacement bids.
The La Porte City Board of Public Works on March 17 voted to accept an assessment proposal to model a chronic combined-sewer area around Lawrence and East Jefferson streets. Staff said the assessment will use local surveying and sewer-flow meters the city crew will install; modeling will allow engineers to run ‘‘what-if’’ scenarios to compare tanks, pump stations or relief sewers and identify the most cost-effective solutions. Staff said meter calibration requires storm events and that a preliminary design could be available by midsummer.
The board also approved a $10,975 basement-backup grant for a property at 601 Lincoln Way; under the award the city’s share was listed as $4,750 and the homeowner’s share $6,225. Staff said the grants address immediate basement flooding risks while larger, multi-million-dollar sewer separation projects proceed.
Separately, the board authorized staff to solicit appraisals on three parcels adjacent to the wastewater treatment plant to secure land for current and future headworks and gravity-sewer connections. Board members also reviewed two sealed quotes to remove aging underground fiberglass fuel tanks (installed in 1987) as the city transitions to natural-gas generators; the bids were $45,400 (SCS Environmental Contracting) and $36,427 (Who's Your Equipment). Staff will return with a recommendation after engineering and legal review.
Taken together, the decisions advance near-term flood protection for individual properties and a data-driven approach to long-term drainage solutions.
