Tax Information, Forms & Tools

The Safe, Clean Water Program is funded by a tax on private properties that contribute to stormwater pollution.

The Safe, Clean Water Program is funded by a tax on private properties that contribute to stormwater pollution. The Program helps property owners understand how they are taxed, how they can become eligible for exemptions, reductions, or credits, and how they can appeal.

The tax is calculated for each applicable parcel based upon the parcel’s impermeable area (think buildings, roofs, driveways, sidewalks, sheds, and pools) as determined by the County Landcover Survey (or other applicable tool). The Board of Supervisors will periodically initiate an update to the County Landcover Survey.

The chief engineer may periodically re-evaluate the characteristics of parcels to ensure accuracy of tax calculations.

Property owners who demonstrate stormwater improvements that result in water quality benefits, water supply benefits, and community investment benefits are eligible for the credit program. 

A Credit Trading Program (CTP) is currently in development and proposed to be available for eligible property owners to purchase and sell credits to satisfy special parcel tax obligations. Credits earned from demonstrating stormwater improvements but not applied in the Credit Program will be eligible for trading.

There are two options for exemption:

Qualifying low-income senior exemption 

Low-income senior property owners may apply annually for an exemption from this special parcel tax. In order to qualify, the applicant must be 62 years of age or older, reside in a single-family residence, be the sole maintainer of the home, and qualify as a low-income household, as determined annually by the California Department of Housing and Community Development.

Ad valorem property exemption

Parcels that are exempt from ad valorem property taxes are also exempt from this special parcel tax. This includes qualifying non-profit organizations and other exempt properties. This exemption will be automatically applied to the tax bill with no action required of the property owner.

 

There are two options for reduction:

General income-based reduction

Through the General Income-based Tax Reduction Program, very low-income and extremely low-income household parcel owners may receive a reduction from the special parcel tax. Qualified households will receive a reduction percentage based on the household income and number of persons in the household.

Property owners who believe their tax has been calculated incorrectly can file an appeal with the LA County Flood Control District on the following grounds:

  • Mathematical error in the calculation of the tax.
  • Significant discrepancy between the assessed and the actual impermeable area.

Property owners may submit appeals through the online appeals tool.
