Soil Testing Application and Inspection Process
All properties are either served by public sewer or a private septic system as its means of wastewater disposal. Properties that are ineligible for public sewer service must complete satisfactory water table tests and percolation or sand mound testing to establish a sewage disposal area on the property before it can be considered buildable.
🆕 Applications are currently being accepted for the 2025 Water Table Season. However, the wet season opening date is yet to be determined as groundwater levels remain below average. Please refer to the 2025 Wet Season Memo for more details, and check back here for updates.
