The Drainage Charge Estimator can provide a rough estimate of your future drainage charge. In general, the more accurate the information you enter into the calculator the more accurate the estimate is likely to be. View our frequently asked questions for more information about how the charge will be calculated.

 

 
(You can estimate by measuring buildings, driveways, garages, decks, walkways, etc., or by using the ruler tool on free Google Earth Pro software. The City uses aerial photography, permit information and GIS as data sources.)

 
(You can estimate by measuring property boundaries or by getting information online from the Travis Central Appraisal District, Hays Central Appraisal District or the Williamson Central Appraisal District. The City uses the appraisal districts and GIS as data sources.)
