Storm Water Fee Calculator: Estimate you storm water charge based on proposed storm water rates.

Background on Storm Water 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. Today, the storm water fee is paid for out of the customer’s water charges. Storm Water and regular water usage do not correlate. To create a more fair rate and follow best practices, the city proposes a new storm water fee structure.

Objectives of a New Storm Water Fee Structure

  • Remove storm water from the water rate
  • Create a fair and equitable fee structure for storm water, reflecting drainage or runoff
  • Create a stable revenue stream
  • Involve stakeholders to build understanding and acceptance 


Storm Water Fee Frequently Asked Questions

Q. What is stormwater runoff?

A. Stormwater is the water that flows off roofs, driveways, parking lots, streets, and other hard surfaces during rainstorms. Some precipitation soaks into the ground and becomes part of the soil but most of it runs over land or through streets, channels, ditches, and drains and into our bodies of water.

Q. Why is stormwater runoff a concern?

A. Flooding occurs when stormwater runoff exceeds the capacity of an under capacitated ditch, drain, or channel. Adverse impacts include pipe dislocation, property damage, poor water quality and possible loss of life.

Q. What are stormwater systems?

A. A stormwater system is designed to minimize flooding and prevent water pollution. It collects stormwater runoff, dissipates energy (reduces the speed of flowing water), removes debris, and safely channels the flow to a designated collection point or receiving stream.

Q. What are the activities involved in maintaining a storm water system?

  1. Maintenance of channels, ditches, mains, inlets and pump stations maintenance
  2. Management of vegetation to ensure its growth does not impair storm water flow
  3. Flood control and flood warning system
  4. Inlet basket cleaning
  5. Street sweeping
  6. Municipal Separate Storm Sewer System (MS4) permit compliance
  7. Water quality monitoring
  8. Infrastructure repair and replacement, including inspections and asset management
  9. Engineering


Q. Is the City’s storm water system adequate for managing its storm water?

The City’s current storm water program does not adequately meet the needs of our growing area. Staff are currently examining where investments should be made for the safety of our residents, the health of our environment and the beautification of our City. After reviewing what other cities in Texas and across the nation are doing, and comparing that with Corpus Christi’s current system, several program enhancements have been identified to bring the system up to par. They include:

  1. Capital improvements
  2. Engineering
  3. Flood control
  4. Public education and outreach
  5. Monitoring pipe outfall water quality
  6. More frequent street sweeping
  7. Floatable debris removal
