What this means
What the soils in Broward County mean for gardens, lawns and septic systems
For your garden
Typical topsoil in Broward County is moderately acidic: pH 5.8 (most land between 5.3 and 7.9). Many vegetables grow well here, and some gardens benefit from a little lime. Test before adding any.
Organic muck or peat is the most common topsoil (54% of the land). It is rich and holds water, but is often wet, can be acidic, and settles when drained. The most common surface texture is muck (54% of the land).
87% of the land is somewhat poorly to very poorly drained, so soil stays soggy for long spells after rain and in wet seasons. Raised beds, plants that tolerate wet feet, and not working the soil while wet all help.
For your lawn and yard
On 81% of the land, rain soaks in slowly (hydrologic groups C and D, including dual groups that are D until drained). Expect runoff and puddles after heavy rain: core-aerate compacted lawns and keep ground sloping away from foundations.
A seasonal high water table comes within 18 inches of the surface on 81% of the land, often in spring. Basements, sump pumps and lawns in low spots feel it first.
For a septic system
For conventional septic absorption fields, NRCS rates 91% of the land in Broward County very limited, 0% somewhat limited and 0% not limited (9% not rated, such as urban land, pits or water).
That is close to the state as a whole (87% very limited).
Where the soil is very limited (slow permeability, a high water table, flooding, shallow bedrock or steep slopes), alternative systems such as mound or sand-filter designs are common and cost more.
Flooding is mapped on 45% of the land (0% occasional, 45% frequent).
Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
Drainage
How long the soil stays wet
The most common drainage class is very poorly drained (56%). 4% of the land is moderately well drained or better, compared with 24% across Florida.

Septic absorption fields
NRCS rating for conventional drain fields
The rating looks at the soil from 24 to 60 inches deep: permeability, depth to a seasonal water table or bedrock, flooding and slope. “Very limited” means at least one feature is unfavorable enough that a conventional field is hard to make work.

- SSURGO as published on November 3, 2026 (most recent survey area update October 26, 2026). NRCS refreshes SSURGO each October.
- Scope
- Broward County, Florida (FIPS 12011): 503,096 acres of mapped land, 23,655 acres of open water excluded. State comparisons pool all mapped land in Florida.
- Method
- Shares are by mapped land area: each map unit’s acres in the county times each soil component’s percentage. Open water is excluded. Topsoil values use the first mineral horizon of each component. Full methodology.
