NORTH PORT — City commissioners unanimously agreed Monday to pursue a capital assessment methodology study on how to fund a projected $46 million road improvement project expected to span several years.

Under the proposal, the average residential property owner would pay roughly $46 per year, in addition to the current Road and Drainage assessment of about $100. The funding from the voter-approved bond will be used to upgrade substandard roads over three years, according to city Community Outreach Manager Erin Bryce.
