severance-damages-quantification
Expert in calculating loss of value to remainder parcels from partial takings including access impairment, shape irregularity, utility loss, and farm operation disruption. Use when quantifying severance damages, analyzing access impacts, valuing irregular remainders, assessing development yield loss, or calculating agricultural division costs. Key terms include severance damages, access impairment, landlocked parcel, shape irregularity, highest and best use loss, development potential reduction

What it does
Provides detailed methodology for quantifying severance damages to remainder parcels from partial takings, focusing on access impairment, shape irregularity, utility impairment, and farm operation disruption. Applicable to determining losses in frontage value, circuitous access, landlocked conditions, irregular layouts, development yield, and agricultural division costs.
How it works
- Access impairment: assigns frontage values by road class in $/linear foot, then calculates losses from direct frontage removal; uses circuitous access modeling with time-distance methods and value-of-time to estimate annual losses; discusses traffic-count related rent/sales impact.
- Landlocked remedies: outlines costs to acquire or secure easements (or court-ordered) and compares with potential 60%+ reductions if no easement, including example calculations.
- Shape irregularity: uses geometric efficiency ratios (area to perimeter) to derive an efficiency index; maps indices to value loss ranges; provides example of severance damage tied to efficiency decline.
- Development yield analysis: estimates reduced buildable area and units, compares pre- and post-taking yields and values, presents both proportional and per-acre approaches.
- Comparable sales for irregular parcels: demonstrates discounting based on shape to adjust value per acre.
- Utility impairment: discusses loss of highest and best use when zoning permits are constrained; compares before/after subdivision values under different use scenarios.
- Reduced development potential: analyzes site constraints affecting buildable area, parking, and site capacity with step-by-step before/after calculations.
- Site servicing: lists relocation costs for water, sewer, electrical, gas, plus drainage and grading costs, with totals.
- Farm operation disruption: covers field division fencing, drainage modifications, equipment access time-cost modeling, irrigation pivots disruption, and cost-to-cure vs value-loss alternatives.
When to use it
Use when a partial taking triggers measurable value changes in remainder parcels due to access loss, shape changes, utility disruption, or farming operations. Apply the explicit formulas and example figures to compute severance damages for each applicable category.
What it can touch
- Tools: claude-code (as declared)
- It references calculations and valuations (e.g., $/linear foot, per-acre values, capitalization rates) and operational costs, but does not specify executable scripts beyond the declared capability.
Caveats
- Provides explicit monetary examples and ranges, which should be adapted to project-specific data; no guarantees of outcome beyond the stated methods.
- Values, rates, and costs are example-driven and may vary by jurisdiction and market conditions.
You are an expert in calculating loss of value to remainder parcels resulting from partial property takings, providing detailed methodology for quantifying severance damages across access, shape, utility, and agricultural operation impacts. ## Granular Focus Calculating loss of value to remainder parcels (subset of partial taking expertise). This skill provides deep, focused methodology for quantifying specific types of severance damages - NOT general partial taking theory. ## Access Impairment Analysis Quantifying reduced access value from loss of frontage, circuitous access, or landlocked conditions. ### Direct Frontage Loss ($/Linear Foot by Road Classification) **Methodology**: Value contribution of road frontage analyzed by linear foot based on road classification and development potential. **Highway frontage (400-series, divided highway)**: - **Commercial development potential**: $500-$1,500/linear foot - **Industrial development potential**: $300-$800/linear foot - **Residential development potential**: $150-$400/linear foot **Arterial road (4+ lanes, signalized intersections)**: - **Commercial**: $300-$800/linear foot - **Industrial**: $200-$500/linear foot - **Residential*

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill severance-damages-quantification-reggiechan74-vp-real-estate-110 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
