Stormwater Drainage Rates
Residential Property
Single family residential property owners within the Edmond city limits pay a flat fee for drainage based on each developed lot, tract, or parcel that is on record with the County Clerk. The flat fee is $3 per lot, tract or parcel. For duplex or multi-family apartments that have two or more dwelling units on the same lot, tract or parcel, the drainage fee is $1.50 each.
All Other Real Estate
The impervious (or non-absorbent) surface of all other lots, tracts or parcels of developed real estate within the Edmond city limits is measured to determine the Equivalent Surface Units. To determine the Equivalent Surface Unit, the total square feet of impervious surface area is divided by 4,860 square feet, which is the average imperious area for single family residential property. The service charge is $3 for each Equivalent Surface Unit or portion of a service unit.
There are no caps on the monthly service charge rate.
