Glades County, FL

Glades County, located in central south Florida, was founded in 1921. Its name was derived from the Florida Everglades, the last remaining U.S. subtropical wilderness formed by waters flowing to Biscayne Bay from Lake Okeechobee adjacent east of the county.

The whole area of Glades County totals 987 square miles, with land accounting for 806 square miles and the rest is water including a portion of Lake Okeechobee. Glades’ county seat and largest city is Moore Haven on the southwest shore of this 730-square-mile lake. The county’s other population centers are the census-designated place of Buckhead Ridge and the unincorporated communities of Palmdale, Muse and Lakeport.

Agriculture Base

From its formative years, Glades has nurtured agriculture which remains one of its primary industries. The county to date still has significant acreages growing sugarcane, orange fruits and livestock. The county’s agricultural strength has become a platform for other economic areas such as food processing and renewable energy generation.

Glades has likewise parlayed its central south Florida location to harness its potential as a regional logistics hub. Significantly, just over two hours’ trip separates this county from Fort Lauderdale, Miami, Orlando, and Tampa. With West Palm Beach and Orlando likewise as close, Glades has the markings of a strategic channel for warehousing and the distribution manufactured goods by road, rail and air.

Marine Industry-Friendly

Notably, Glades county seat Moore Haven, is on the Okeechobee Waterway, a vital connection to the east and west coasts of Florida. Given its location, the city offers marine industries safe and affordable harbor for vessels coming from the Gulf in Fort Myers.

Choices for business locators in the county include the 770-acre rail-served Americas Gateway Logistics Center and the Glades County Business and Commerce Park and. The facilities in place in these two business hubs are mixed lot and suitable for commercial operations as well as heavy industry. Tax incentives and the availability of a growing workforce further make Glades a hotspot in the Florida commercial real estate sector.

Nature-based tourism is as hot in Glades, as the county provides delightful destinations for fishing, hunting, biking, boating and birdwatching. Fisheating Creek is one of the top local draws, providing over 100 miles of paddling trails and choice fishing grounds. More of the same could be enjoyed at Buckhead Ridge popular for its bass fishing tournaments and duck hunting.

Glades tourists who find themselves perennially planning trips could eventually choose to settle in the county permanently. Being mainly rural, this county is less densely populated, with its residents totaling under 14,000, and it thus would appeal most to folks who prefer a laid-back countryside lifestyle.

Real estate buying opportunities in Glades County consists of market listings of affordable single family and multi-family homes, as well as mobile homes and manufactured homes.

Million dollar sales listings of ranch and farm properties are also among the choices in this county’s property market.

Sinkholes in Glades County, FL

Southwest Florida’s unique geology makes it prone to natural ground instability. The area’s karst landscape, formed by ancient limestone, sets the stage for subsurface erosion. Groundwater movement, influenced by Lake Okeechobee, plays a key role in sinkhole formation.

State geologists use specific criteria to classify areas. FDEP risk assessments show Glades County FL is at risk due to its wet-dry cycles. USGS surveys reveal that bedrock collapse is rare, despite seasonal changes in underground pressure.

Between 2003 and 2023, there were few sinkhole incidents. No major property damage was reported. Monitoring systems track changes in elevation and aquifer levels to spot early signs. This approach helps manage risks in Florida’s geologically active areas.

Recent & Notable Sinkhole Incidents / Case Studies

Glades County in Florida has one of the lowest rates of sinkholes, with less than 0.3 incidents a year. This is much lower than neighboring counties with more limestone, which increases the risk of sinkholes. Between 2003 and 2023, only two events were officially confirmed as sinkholes through insurance records.

2008 Subsidence Near Moore Haven: A 14-foot depression was found 3 miles from Lake Okeechobee. Tests showed that limestone was dissolving at 23 feet deep. To stop damage, engineers used 180 cubic yards of grout to stabilize the area.

2015 Fisheating Creek Depression: A 9-foot shift was seen near Fisheating Creek. It was later found that decaying cypress roots were causing the soil to compress. This was not a true sinkhole, as there was no connection to the aquifer.

Factor Glades County Hernando/Pasco Counties
Annual Incidents per 100 sq mi 0.28 14.6
Surface Sediment Depth 40-65 ft 8-22 ft
Aquifer Level Fluctuation ±1.3 ft/yr ±4.8 ft/yr

Glades County is stable for three main reasons:

  • Thick Hawthorne clay layers protect the limestone below
  • Little groundwater pumping keeps pressure steady
  • No big phosphate mining operations

In Glades County, FL, only 17% of land depressions from 2003 to 2023 were real sinkholes. Most were due to normal soil settling or decomposing debris. This is different from central Florida, where 89% of similar reports were karst-related collapses.

Risk Factors & What Homeowners Should Do

Glades County FL has unique geological challenges that lead to sinkholes. The use of too many irrigation wells and tropical storm runoff are big problems. These factors make the ground unstable.

Lower water tables weaken the limestone bedrock. Heavy rains also cause soil erosion. Taking steps to prevent these issues can help protect homes.

Homeowners should get ASTM D4435 soil tests before building. These tests show if the ground is stable. The Glades County Building Department requires special foundations in risky areas.

Regular checks are key to catching problems early. Use crack gauges on foundations and walls. Take photos and measure changes often.

Florida Senate Bill 742 makes it clear what sinkhole coverage means. Check insurance policies every year. Look for “catastrophic ground cover collapse” in the fine print.

If you see sudden changes in the ground, tell the Florida Department of Environmental Protection. The Glades County Sinkhole FL team will check it out fast. If you’re worried, get a professional to look at your home. Keep drainage systems working to avoid water problems.

FAQ

What makes Glades County geologically susceptible to sinkholes?

Glades County’s karst landscape is made of porous limestone. This bedrock was formed during the Everglades geological period. It has documented carbonate rock layers and seasonal water table changes.USGS surveys show how Lake Okeechobee’s groundwater interacts with this bedrock. This interaction creates structural vulnerabilities. But, FDEP says the area is lower risk than Florida’s Sinkhole Alley counties.

Have significant sinkholes occurred recently in Glades County?

FDEP records show fewer than 0.3 verified sinkhole incidents annually. A 2008 subsidence near Moore Haven required grouting repairs. A 2015 depression near Fisheating Creek was later found to be caused by decomposing vegetation, not karst collapse.These rates are 95% lower than Hernando County’s activity levels.

How does Glades County’s sinkhole risk compare to Pasco County?

Glades County has 92% fewer sinkhole incidents than Pasco County. This is due to thicker surface sediments (15-30 feet vs. 0-10 feet in Pasco) and more stable aquifer levels. Lake Okeechobee’s hydrological influence helps maintain these levels, as documented in FDEP comparative analyses.

What proactive measures should Glades County homeowners take?

The Glades County Building Department recommends ASTM D4435 soil testing before construction. They also suggest installing foundation crack monitors. Following sinkhole-resistant standards is advised, using reinforced slab foundations or helical pier systems.FDEP advises reviewing Florida Senate Bill 742 insurance requirements. They also recommend monitoring irrigation well usage.

Does homeowners insurance cover sinkhole damage in Glades County?

Florida law requires insurers to offer catastrophic ground cover collapse coverage. But, sinkhole damage policies vary. Property owners should consult licensed adjusters and review policy details under Senate Bill 742 provisions.They should pay special attention to structural damage verification thresholds.

How should residents report suspected sinkhole activity?

Suspected ground subsidence must be reported to the Florida Department of Environmental Protection’s Geotechnical Investigation Section. The Glades County Emergency Management Office works with FDEP to investigate claims.They use ground-penetrating radar and borehole sampling per state protocol.
