FY20 Stormwater Rate Changes

Stormwater Tiered Rate System – Effective October 1, 2019

Single-Family Properties

Effective October 1, 2019, upon City Council approval, the City of St. Petersburg will be implementing a tiered billing structure for stormwater rates for single-family properties. This new tiered structure will classify single-family properties into tiers, based on the square footage of impervious surface area (surfaces that water runs off), so that a property’s fee more accurately reflects its impact to our stormwater system.

Preliminary Single-Family Impervious Tiers and Rates
Billing Structure Minimum Impervious Surface Area Maximum Impervious Surface Area Preliminary Stormwater Billing Rate
Tier 1 1 sq. ft. 1,600 sq. ft. $5.00
Tier 2 1,601 sq. ft. 3,200 sq. ft. $10.00
Tier 3 3,201 sq. ft. 4,800 sq. ft. $16.00
Tier 4  4,801+ sq. ft.   $24.00

Non-Single-Family Properties

Non-single-family (commercial) properties will continue to be charged a fee based on the number of Single-Family Residential Units (SFRU’s) their impervious area represents. One SFRU is equal to the impervious surface area of a typical single-family property in the City, which has been determined to be 2,388 square feet of impervious surface area.

Example of SFRU Calculation (preliminary numbers):
1 SFRU =2,388 square feet of impervious surface area
Monthly rate per SFRU of $10.00 (preliminary, subject to change)
Commercial Property has 23,880 square feet of impervious surface
23,880 square feet of impervious area of the property / 2,388 square feet per SFRU = 10 SFRU’s
10 SFRU’s x $10.00 = $100.00 monthly stormwater utility fee

Next Steps

Starting April 15, customers will be able to view their property’s impervious surface area measurement in the Stormwater Review and Appeals Portal, which can be found in the box below. Through this portal, customers will be able to submit an appeal for reevaluation if they feel the property has been measured incorrectly.
