Texas Local Government Code - LOC GOV'T § 552.066. Apportionment of Assessments

(a) Except as provided by Subsection (c), the municipality shall separately compute the cost of the water or sewer improvements and shall apportion the part of the cost of those improvements that may be assessed against the benefitted property and the owners of the property, among the parcels of the benefitted property and the owners, in accordance with the front foot rule.

(b) Under the front foot rule, the governing body of the municipality shall assess each parcel of benefitted property according to the number of lineal feet of the parcel that abuts on a public street, irrespective of the location of improvements constructed under this subchapter relating to that parcel if the improvements provide water or sewer service to the assessed parcel. The governing body shall assess a corner lot based on the shorter side of the lot that abuts on a public street.

(c) If, in the opinion of the governing body, application of that rule would result in injustice or inequality in particular cases, the governing body shall apportion and assess those costs in the proportion it considers just and equitable, taking into account the special benefits in enhanced value to be received by those owners, and shall adjust the apportionment so as to produce a substantial equality of benefits received and burdens imposed.
