Sioux City advances 27.4% sewer rate hike and 300% stormwater fee increase

Sioux City advances 27.4% sewer rate hike and 300% stormwater fee increaseThe Sioux City Council has approved the first reading of a major sanitary sewer rate increase that triggers a six-month notification period for neighboring municipalities, alongside sweeping adjustments to stormwater maintenance fees.

Council members advanced a 27.4% sanitary sewer rate increase, selecting the largest of three proposed rate scenarios.

The initial sewer rate approval initiates a mandatory six-month notification countdown for other connected cities.

A parallel ordinance advances a 300% increase to the city's stormwater program maintenance fee, which includes a proportional fee cap for non-profit organizations.

The Council approved the Larsen Park Road flood repair project, which includes resetting a compromised sanitary sewer manhole and replacing a sewer line.

A PFAS class-action settlement statement with BASF Corporation was approved, marking the city's fifth such settlement distribution.

The Sioux City Council is moving forward with substantial increases to its municipal utility rates following the advancement of two major ordinances on April 27, 2026. Council members approved the first reading of a 27.4% sanitary sewer rate increase, advancing the most aggressive of three proposed rate scenarios. The initial approval of the sanitary sewer amendment triggers a mandatory six-month notification countdown for neighboring municipalities that utilize the city's wastewater infrastructure. Public Works Director Tom Pingel confirmed to the council that the initial reading formally begins this notification process. The first reading passed with a 4-1 vote, and the council opted not to waive the second and third readings to ensure standard procedural review. In a parallel move, the council approved the second reading of an ordinance modifying the city's stormwater collection fee. Environmental Services staff confirmed the amendment implements a 300% increase to the stormwater program maintenance fee. The ordinance also adjusts a special rule for non-profit organizations, maintaining a maximum fee cap that scales proportionally with the 300% baseline increase, a point of debate among council members regarding equitable tax burdens. Alongside the rate adjustments, the council authorized several water and wastewater infrastructure actions. This includes the approval of plans, specifications, and estimated costs for the Larsen Park Road flood repair project. City Engineer Gordon Ferris noted the project will address cavernous undermining at the site, backfill eroded areas, reset a compromised sanitary sewer manhole, and replace a sewer line serving a local facility. Additionally, the council approved plans for a fiscal year 2026 undersized water main replacement project and signed off on a settlement statement with BASF Corporation regarding ongoing PFAS class-action litigation. City staff noted this represents approximately the fifth settlement payment the city has processed, with more phased distributions expected as the broader litigation continues.
