Stormwater

Rates pay for construction and maintenance of Fort Collins' stormwater system, which helps protect residents and businesses during storms and floods. All developed properties within city limits pay stormwater rates, which are based on:

• Lot Size - lot area in square feet, plus the customer's share of open space in the development, if applicable
• Base Rate - $0.0041454
• Rate Factor - based on the percentage of impervious area (surfaces that do not absorb water) such as buildings, parking lots and concrete

Formula for Estimated Monthly Rates:

• Single-family Lots Under 12,000 Square Feet
  Monthly Rate = Lot Size x $0.0041454 x Rate Factor
• Single-family Lots Over 12,000 Square Feet*
  Monthly Rate = 12,000 x $0.0041454 x Rate Factor plus (Lot Size - 12,000) x $0.0041454 x Rate Factor x 0.25
  *These lots receive a reduction in fees on that portion of the lot greater than 12,000 feet.
• Duplex and Multi-Family Lots
  Monthly Rate = Lot Size x $0.0041454 x Rate Factor
