Storm Water Utility Fee

The City of Corpus Christi began funding storm water via the water rate in 1989. The EPA issued the first National Pollutant Discharge Elimination System (NPDES) and Municipal Separate Storm Sewer System (MS4) permit to the city in 1995. In 2008, the city established a separate fund to support storm water. In September 2021, the city adopted a storm water fee structure.

The Storm Water Utility Fee is based on the amount of impervious surface on each property and is developed using an Equivalent Residential Unit (ERU). Each ERU is equivalent to 3,280 square feet of impervious area. Residential customers will fall within a tier and non-residential will be individually calculated based on the property’s specific impervious area.
