1250 West Avenue — Independent Economic Rebuttal

An independent, data-driven economic analysis rebutting the City's third-party report on the proposed 1250 West Avenue development and the Alton Beach Bayfront Overlay density and height bonuses.

Overview

Grounding a high-stakes entitlement decision in market reality

The City of Miami Beach commissioned a third-party economic analysis to estimate the value the developer would realize from density and height bonuses requested under the Alton Beach Bayfront Overlay for the proposed 1250 West Avenue condominium. BusinessFlare® was engaged to independently review that analysis and provide an accurate, defensible assessment of the project's true economic and public-benefit dynamics.

Our review identified significant methodological flaws — arbitrarily inflated sellable square footage, unrealistic sales-price assumptions, and the omission of major development costs — that materially overstated the incremental value attributable to the bonuses. Working from verified Miami-Dade Property Appraiser transaction data and comprehensive project cost estimates, we recalculated the economics and quantified the public benefits delivered to the City.

How a rigorous, market-grounded methodology corrected an inflated valuation and clarified the project's public value.

We conducted a comprehensive review of the City's third-party economic analysis, documenting specific methodological errors that distorted the estimated value of the requested density and height bonuses. The report inflated sellable square footage, assumed sale prices well above observed transactions, and omitted or understated fundamental development costs — each pushing the incremental valuation toward an unrealistic outcome.

What it includes
  • Identification of arbitrary efficiency assumptions inflating sellable area
  • Documentation of unsupported per-square-foot pricing
  • Analysis of omitted land, financing, and public-benefit costs
  • A side-by-side comparison of the two methodologies

Rather than rely on speculative pricing, we sourced condominium sales directly from the most recent Miami-Dade Property Appraiser Assessor File and validated them against recorded transactions. We broadened the comparable set beyond the narrow overlay district to premium luxury buildings across South Beach, ensuring adequate market depth and a defensible basis for pricing.

What it includes
  • Multi-year sales-per-square-foot data for seven comparable buildings
  • Direct sourcing from the Miami-Dade Property Appraiser
  • A realistic 10–20% high-floor height premium analysis
  • A defensible recommended pricing range grounded in transactions

Accurate valuation requires accounting for the real costs of development. We incorporated land acquisition, realistic construction and soft costs, construction financing, sales and closing expenses, and the public-benefit obligations — categories the original report omitted or understated. We also provided a plain-language explanation of development financing and risk that the public rarely sees.

What it includes
  • Land acquisition treated as a fixed cost in every scenario
  • Construction and soft costs benchmarked to comparable projects
  • Construction financing and carrying costs made explicit
  • Public-benefit obligations quantified with realistic contingency

Instead of isolating bonus square footage in a vacuum, we evaluated the full project economics both with and without the requested bonuses — the only way to properly capture shared and fixed costs. The difference yields the true net benefit attributable to the bonuses: approximately $58 million, far below the inflated figure in the City's report.

What it includes
  • A full “with bonus” vs. “without bonus” project comparison
  • Correct apportionment of fixed and shared costs
  • A transparent, reproducible incremental-value calculation
  • A result grounded in feasibility and developer risk

Beyond the incremental value, we quantified the public benefits tied to the entitlement — park and Baywalk improvements, waterfront access, and strategic property acquisition — estimated at $40 to $50 million, consistent with City estimates. We also projected the recurring ad valorem revenue the completed project would generate for the City and other taxing authorities.

What it includes
  • Quantitative public-benefit package valued at $40–$50M
  • Incremental City general-fund revenue of roughly $1.6M annually
  • Total incremental ad valorem revenue near $4.8M annually
  • Qualitative benefits: waterfront access, parks, and resilience
