Stormwater Utility

Avon’s stormwater utility manages the runoff from rainfall. In nature, water flows from fields to streams to rivers and so on, but commercial, residential and industrial development has changed some of these natural flows. The stormwater system helps to prevent flooding and limits pollutants flowing into streams and rivers.  A property owner’s stormwater bill funds the cost of operations, maintenance, capital projects and planning for future system expansion.

In 2016, Avon conducted a feasibility study that recommended an equitable, research-based structure for potential stormwater customer rates.  The Town accomplished this by instituting rates based upon the amount of impervious surface area on each property.  Impervious surface is a term used for how much property is covered by impenetrable materials (asphalt, concrete, roofs, etc.). 

An average Avon home’s impervious surface area - 3,942 sq. ft. - established the base billing unit, called the Equivalent Residential Unit (ERU). Residential customers will be charged one ERU per month (3 per quarterly billing cycle), while non-residential customers will be charged multiple ERUs per month based on the property’s total impervious area divided by 3,942 sq. ft.

Best of luck on your move! 

You don't have to do anything to stop or change service with us. We collaborate with Hendricks County to obtain an updated list of property owners each quarter. You are responsible for the bill if you were the property owner on record with the Hendricks County Assessor's Office on the first day of the billing quarter, but after that, you shouldn't get any more bills. 

If you're still getting bills, or have additional questions, please give us a call at the Avon Public Works Department 317-272-0948. Be sure to tell the operator you have a Stormwater Utility question.

You will need to complete a Hendricks County Online Change of Address Request Form.  You can download a PDF instruction sheet HERE.

The Stormwater Utility is billed quarterly to the property owner on record with the Hendricks County Assessor's Office on the first day of the quarter. 
If you have further questions, please call the Avon Public Works Department at 317-272-0948 and tell the operator you have a question about the Stormwater Utility.

We're sorry about that! Please call the Stormwater Utility customer service line at 833-286-9057. 

The Stormwater Utility Board approved several drainage improvement projects in June 2018. Check the Stormwater Utility Capital Improvement Project to see if your area has already been included on this list.

Avon town officials commissioned a feasibility study in 2016 to look at an equitable, research-based structure for potential customer rates.

The potential rates are based upon the amount of impervious surface area on each property. Impervious surfaces – roofs, paving, concrete, gravel, etc. – do not allow stormwater to soak into the ground. Impervious surfaces increase urban runoff that must be directed through drainage infrastructure. More runoff creates more demand for infrastructure.

The study calculated the average impervious area from the residential customer class to establish the base billing unit, called the Equivalent Residential Unit (ERU). Residential customers would be charged one ERU per billing cycle. Other customer classes would be charged multiple ERUs per billing cycle based on the property’s impervious area ratio to the base billing unit.

Customer Class Rates:

These rates were adopted by the Avon Town Council on November 16, 2017 (Avon Ordinance 2017-25)
