Many Alachua County property owners and buyers do not know whether a parcel falls inside an area with enhanced septic requirements.
The answer is not the same throughout the county. It can depend on the basin, lot size, whether the system is new or existing, whether a permit is needed, and whether central sewer is available.
Search the official map
Look up the property before making plans
Enter the street address, review the map layers for new or existing systems, and then confirm the result with the permitting office.
Check the property on the official mapWhy the address alone is not enough
Basin and priority focus area boundaries can run through communities. Two properties with the same city or ZIP code can fall under different requirements.
After locating the address on the map, open the Layers menu and select the information that matches the situation. Someone evaluating an existing system should filter out layers labeled for new systems only. The map is a spatial reference, not a final permitting decision.
Silver Springs Basin
According to Alachua County Environmental Protection Department guidance dated August 6, 2026, the Silver Springs Basin Management Action Plan went into effect in 2026.
- New septic systems on lots of any size must use an approved enhanced nutrient-reducing system.
- Existing conventional systems on lots of any size are scheduled to be upgraded by 2046.
- An upgrade may be required sooner when an owner applies for a repair permit.
These requirements may affect properties in eastern and southeastern portions of Alachua County. Check the parcel rather than relying on the community name.
Santa Fe Basin
The Santa Fe Basin includes the Hornsby Springs and Devils Complex priority focus areas.
- Within those priority focus areas, new systems on lots of any size must use enhanced nutrient-reducing treatment.
- Elsewhere in the Santa Fe Basin, the enhanced requirement applies to new systems on lots of one acre or less.
- The current county guidance does not require an existing working system throughout this basin to be upgraded solely because of the new rules.
The basin reaches portions of northern and western Alachua County, including areas near High Springs, Alachua, La Crosse, and Newberry. The larger Santa Fe watershed also extends beyond Alachua County, so North Florida properties outside the county should be checked using the state map and their local permitting authority.
Orange Creek Basin
In portions of the Orange Creek Basin that do not overlap the Silver Springs Basin, new systems on lots of one acre or less must use enhanced treatment.
The current guidance does not require existing systems in those portions of the Orange Creek Basin to be upgraded. Where the Orange Creek and Silver Springs basins overlap, the Silver Springs requirements apply.
Could rebate assistance help?
Alachua County currently advertises limited rebates for qualifying property owners who upgrade existing septic systems to enhanced nutrient-reducing systems. The county states that assistance may be available up to $16,000, depending on the qualifying system and program requirements.
Confirm eligibility before signing a contract or beginning work. Funding is limited and program terms can change.

Common questions
How do I know whether a property is affected?
Search the address on the official map, select the relevant new-system or existing-system layers, and confirm the result with the permitting office.
Does every existing system need to be replaced now?
No. The rules differ among the Silver Springs, Santa Fe, and Orange Creek basins. An existing system can also be treated differently from a new system or a permitted repair.
Does a High Springs, Gainesville, Alachua, or Newberry address determine the answer?
No. Basin boundaries do not follow mailing addresses or city limits. The parcel must be checked on the map.
Who makes the final determination?
The applicable permitting authority should confirm what is required for the property and proposed work. In Alachua County, the county directs permitting questions to the Alachua County Health Department at 352-334-7930.
