Based on the provided information, the deductible for standard sinkhole insurance coverage in Florida is generally structured as follows:

• Standard Sinkhole Activity Coverage: This typically carries a separate deductible that approximates 10 percent of the dwelling limit.
• Policy Variations: Deductible structures can vary significantly depending on the specific insurance provider (such as Tower Hill Insurance) and the individual terms of your policy.
• Catastrophic Ground Cover Collapse: This type of coverage is distinct from standard sinkhole insurance and may have its own separate deductible structure.

Because coverage and costs are tied to the specific terms found on your insurance declaration page, it is recommended that you review your individual policy or consult with your insurer to determine the exact deductible amount for your property.
