Equivalent Residential Unit (ERU) An equivalent
residential unit is the base billing unit that is
established for the purpose of standardizing
stormwater fees and allocating costs, based on
impervious area, to different property types. One
ERU is equal to the amount of impervious area
(e.g., rooftops and paved areas) that can be
found on a typical single-family residential
property and was determined to be 2,700 square
feet in South Burlington.
23Where do we go from here?
- If the South Burlington model is an avenue the
Mayors Task Force wants us to pursue more work
can be done - If there is another preferred path that can be
explored
