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.
🆕 Soils Testing applications for the 2025 wet season are no longer being accepted. Due to drought conditions and insufficient water table levels, the 2025 Wet Season will remain closed. Please refer to the 2025 Wet Season Update Memo for more details and check back here for updates.
