  • The residential property owner charge is determined by a property‚Äôs estimated amount of impervious surface area.   
  • An Equivalent Residential Unit (ERU) of 2,940 square feet represents the median amount of imperviousness for properties in residential zones 1, 2 and 5.  
  • An ERU is the base unit for calculating the annual charge.  
  • Base annual rate for one (ERU) is $85.  
  • Properties are divided into separate billing tiers and represent zoning districts with an estimated imperviousness that is less than, equal to or greater than the base ERU of 2,940 square feet.
  • Recently approved legislative amendments provides an initial  60% phase (Fiscal Year 2014) and 80% for the year two (Fiscal Year 2015).

BASE RATE  =  $85 per ERU per year
