The most overlooked component of just compensation isn't the value of what was taken. It's what happens to what's left. Severance damages — the loss in value to the remainder caused by the partial taking — are often the largest single piece of a meaningful condemnation recovery, and they are frequently undercounted by both agencies and inexperienced counsel. Here's the working framework.
The principle
When the government takes part of a parcel, the parts left behind often function less well than they did before. Strip takings for road widening can leave shallow remainders. Easement corridors can divide pastures or interrupt access. Drainage improvements can change flooding patterns on adjacent land. Each of these effects reduces the value of the remainder, and each is part of just compensation.
Federal and state law have long recognized severance damages as an essential component of compensation in partial-taking cases. The doctrinal foundation is consistent across jurisdictions; the implementation is where the work happens.
The before-and-after measure
Most jurisdictions, including Alabama and Florida, measure compensation in a partial taking using the before-and-after rule:
- Before value: the fair market value of the entire property as it existed before the taking.
- After value: the fair market value of the remainder after the taking, considering the impact of the taking and the project on the remainder.
- Compensation: the difference between the two, with appropriate allocation between the value of the part taken and the severance damages to the remainder.
The advantage of the before-and-after measure is that it captures all components of the compensation owed in a single coherent calculation. It also pushes the analysis toward documentary, market-based evidence rather than contested theoretical breakdowns.
What drives severance damages
The substance of severance damages is the impact on the remainder. The most common drivers:
Loss of access
Road projects routinely affect access. A parcel with full curb-cut frontage may end up with right-in/right-out only, no median crossover, or no direct access at all. Each of these significantly affects commercial property values, and the impact is often the largest single component of severance damages in retail or hospitality cases.
Loss of frontage and visibility
Highway-visible signage and storefront exposure are tangible value drivers for many businesses. Project changes that move the right-of-way line, install sound walls, or alter line-of-sight directly affect visibility and therefore value.
Functional area reduction
A taking that leaves the remainder with insufficient depth, irregular shape, or inadequate parking can shift the highest-and-best-use category itself — a property that supported a hotel may now only support a fast-food pad, with corresponding value implications.
Operational disruption
For active commercial or industrial operations, the geometry of the remainder may force expensive layout changes, rerouting of internal traffic, relocation of utilities, or modification of structures. Each of these can be reflected as a cost-to-cure (where applicable) or as a value-impact component of severance damages.
Drainage, grading, and topography
Highway and infrastructure projects routinely alter the topography around them — fill, slopes, drainage swales — in ways that affect remainder usability and stormwater management. These technical issues often require both an appraiser and a civil engineer to develop credibly.
Environmental and regulatory consequences
A partial taking can sometimes trigger regulatory consequences for the remainder — wetlands disturbance, setback non-compliance, parking-ratio failure under the zoning code. These should be evaluated and, where applicable, factored into the after-value analysis.
Cost-to-cure
In some cases, modest expenditures can mitigate the impact of the taking — relocating a sign, reconfiguring a parking lot, restoring grade. Cost-to-cure analysis quantifies those expenditures and compares them to the diminution-in-value alternative.
Where cost-to-cure is genuinely sufficient to restore the remainder's function, it is often the more efficient measure. Where the cure cost approaches or exceeds the diminution, diminution is usually the better measure. The analysis should address both, and counsel and appraiser should agree on which to lead with based on the particular facts.
Special benefits — and why they're contested
Both Alabama and Florida (and most other jurisdictions) distinguish between:
- General benefits: increases in value to the remainder that come from the project as a whole, available to all properties in the project area. These are not offsettable against severance damages.
- Special benefits: increases in value to the specific remainder that derive from the project's particular impact on this property, distinct from the public at large. These can sometimes be offset against severance damages, with the rules varying by jurisdiction.
Agencies sometimes argue that nominal "benefits" eliminate severance claims. The owner's response is usually a careful taxonomy of what is general (and not offsettable) versus special (and only offsettable to the extent the law permits). Special-benefits doctrine is technical and often outcome-determinative; it deserves careful case-specific evaluation.
Building the severance case
A defensible severance case generally requires:
- A condemnation-experienced appraiser using the before-and-after methodology.
- Engineering or planning support for the technical impacts (drainage, parking, access, geometry).
- Operational testimony from the owner or operator describing how the property functioned before and how it must function after.
- Comparable-sales evidence supporting the after-value, often including properties with similar impact characteristics.
- Anticipation of the agency's special-benefits theory and a worked analysis of what is general versus special.
Common pitfalls
- Not engaging a partial-taking-experienced appraiser early. Generalists often miss the methodology and produce reports that don't withstand scrutiny.
- Letting the agency define the remainder. What counts as the parcel under valuation can be contested; the right framing usually favors the owner.
- Underestimating special-benefits exposure. Agencies sometimes raise special benefits late, and unprepared owners see severance recoveries reduced or eliminated.
- Failing to coordinate severance with other compensation elements. Severance, business damages, cost-to-cure, and the value of the part taken are interconnected. Inconsistent analyses are a frequent target on cross-examination.

Frequently asked questions
Are severance damages always available in a partial taking?
Whenever the partial taking actually diminishes the value of the remainder, yes. Severance damages are part of just compensation under both the federal and state constitutions, and the statutory frameworks in Alabama and Florida specifically recognize them. The contested issues are usually about magnitude and methodology, not entitlement.
What's the difference between severance damages and cost-to-cure?
Cost-to-cure is the cost of mitigating the impact of the taking on the remainder. Severance damages are the diminution in value of the remainder. The two are alternative or complementary measures depending on facts. Where a cure is feasible and meaningful, cost-to-cure may be the right measure; where it is not, diminution captures the true loss.
Can the agency offset benefits against severance damages?
Sometimes. General benefits — those flowing to all properties in the project area — are not offsettable. Special benefits — those uniquely accruing to the remainder — sometimes are, with the rules varying by jurisdiction. The taxonomy is technical and often outcome-determinative.
How is severance damages proven?
Through expert testimony — usually an appraiser using the before-and-after methodology, supported as needed by engineers, planners, or operators who can articulate the technical and operational impacts on the remainder. The strongest cases combine quantitative analysis with concrete operational testimony from the owner or operator.
Is the remainder always the rest of the parcel I owned?
Usually, but not always. In some cases multiple parcels are treated as a single 'unit of property' for valuation; in others a single parcel is divided. The Supreme Court addressed the relevant-parcel question for regulatory takings in Murr v. Wisconsin, and analogous principles apply in direct condemnation. The right answer is usually obvious but should be confirmed early.
