The calculated assessment is based on Equivalent
Residential Unit (ERU) and considers the size of the
parcel, amount of impervious surface, and land use
of each parcel.
The current ERU fee is $42.46 which was approved
by Council during the 2025/2026 budget process.
3 Annual Storm Water Enterprise Charges on
the Sonoma County Tax Roll
In order to simplify the payment process for property
owners and minimize collection expenses, it is
requested that these charges be collected on the
Sonoma County Property Tax Roll on the City’s
behalf.
The charges have been collected annually on the tax
roll since they were established in September 1996.

It is in the best interest of the City that those parcels not billed by the County due to the charges not
meeting the County’s $10 minimum to bill and/or
parcels with known incorrect ownership contact
information shall not be separately billed by the City, as the cost of separately billing exceeds the potential revenue.
Any charges not collected will not affect other parcel
charges.

the Sonoma County Tax Roll
Today’s public hearing, in accordance with Title 16 of
the City Code, will adopt the Storm Water Enterprise
Charge Report, approve placing the charges on the
County Tax Roll for collection, and allow the public
the opportunity to protest the method of collecting
the charges.
6 Annual Storm Water Enterprise Charges on

It is recommended by the Board of Public Utilities and

and approve placement of the Storm Water Enterprise
charges on the Sonoma County Property Tax Roll to be
collected by the Sonoma County Auditor-Controller-
Treasurer-Tax Collector at the same time and in the same manner as Sonoma County property taxes are collected,
unless those charges do not meet the County minimum
of $10 and/or parcel owner contact information is known to be incorrect.
