There are two steps in calculating the stormwater fee for a commercial property:
STEP 1. Determine the number of ERU’s for the property:
Number of ERU’s = (SFCustomer/SFERU) x (IDFCustomer/IDFERU)
= Equivalent Residential Unit
Square footage of customer’s property
Size of a typical single-family residential property in Titusville, approximately 0.25 acres or 11,000 square feet.
(0.95 x impervious area) + (0.10 x pervious area). Approximately 95% of the rain that falls on the impervious areas of your property (hard surfaces such as driveways and rooftops) will become stormwater runoff and 10% of rain that falls on the pervious areas of your property (grassed or landscaped areas) will become stormwater runoff.
0.30. Approximately 30% of the rain that falls on typical single family residential property becomes stormwater runoff.
STEP 2. Multiply the number of ERU’s by the annual charge per ERU:
2017 Stormwater Fee = (Number of ERU’s) x ($87.70 per ERU)
