Hillsboro homeowners could see another bump in their monthly utility bills next year as city leaders weigh higher sewer and stormwater rates to pay for aging infrastructure and future flood prevention projects.

The City Council reviewed — but did not vote on — a proposal Tuesday that would raise both rates by 5% in 2027 and another 5% in 2028.

Here's what residents should know:

• Average increase: About $4.18 more per month for a typical household beginning Jan. 1, 2027.
• Why it's happening: The city says the money is needed to replace aging sewer and stormwater infrastructure, including projects aimed at reducing flooding.
• One major project: A nearly $24 million replacement of the aging Glencoe Swale culvert, which struggles to handle heavy rain.
• No decision yet: Tuesday's discussion was informational only. The City Council is expected to consider the proposal later this year after a public comment period.

City officials said the proposed 5% increase is the smallest rate hike that still allows Hillsboro to keep up with long-term infrastructure needs. If approved, the new rates would take effect Jan. 1, 2027. Residents will have an opportunity to weigh in before the council votes.
