Cal. SHC § 5882

Upon the completion of the construction, the superintendent of streets shall prepare and file with the legislative body a report specifying the work which has been done, the cost of construction, a description of the real property in front of which the work has been done and the assessment against each lot or parcel of land proposed to be levied to pay the cost or portion thereof. The report may include work done in front of any number of parcels of property, whether contiguous to each other or not. In determining the amount of the assessment against each lot or parcel of land, the superintendent shall assess the same portion of the total cost of the work against each lot or parcel as that parcel will receive of the total benefit from the work.
