Tax Calculation
The tax is calculated for each applicable Parcel based upon the Parcel’s Impermeable Area as determined by the County Landcover Survey or other applicable tool. The boundaries of the area, identification of the Parcels subject to the tax, and the method for calculating the tax for each Parcel is established by the ordinance incorporated by the Los Angeles County Flood Control District Code. The rate used for calculating the tax, as established by the ordinance, will remain the same from year to year. The Chief Engineer may periodically re-evaluate the characteristics of Parcels to ensure accuracy of tax calculations.
The Board of Supervisors will periodically initiate an update to the County Landcover Survey which is used to determine the Impermeable Area for each Parcel throughout the District.
For more information see Section IX of Enclosure E in the Board Letter.
