Non-Residential Stormwater Billing

Non-residential properties (such as commercial or multi-family) are billed based on the actual amount of impervious surface located on the property. Actual impervious surface is determined by using aerial photography that is digitized and matched to the County’s tax records. Stormwater charges for these accounts are based on $3.75 per stormwater unit. One stormwater unit is equal to 2,950 square feet of impervious surface. CCWA customers receive a monthly stormwater fee on their water and sewer bill.

Changes to Impervious Surface Linked to Non-Residential Accounts

These improvements led to reconciled variances in our Billing and Geographic Information System (GIS).  To view the impervious surface linked to your account, click on the following link: Impervious Surface Portal

Non-Residential customers affected were notified via letter.
