The percolation test (aka Perc Test) informs the applicant of how much real estate should be dedicated for sewage dispersal, and more importantly what type of system would be required. In rare cases a parcel can be so impacted that it is considered “unbuildable” by the County so this essential step helps inform a buyer’s decision on building feasibility.


An application for Percolation Test is filled out with the County with applicable fee. In some instances the Perc Test requirement can be waived by the County based on a soil lab test during our prior Site and Soil Evaluation. A “failed” Perc Test is not the “kiss of death” and often lack of experience may cause unnecessary grief and anxiety. We walk our clients through the whole process.
