South Miami delays vote on sweeping downtown zoning rewrite after hours of debate

The City of South Miami on Nov. 4 sent a contentious rewrite of its downtown zoning rules back to the Planning Board after hours of presentation, public testimony and commissioner questions.

Consultants from Corradino Group presented the Transit-Supportive Development District (TSDD) code — a comprehensive zoning chapter meant to guide growth around the South Miami Metrorail station — including three subdistricts, new density limits, a heights map and a suite of development bonuses. The proposal would introduce upper density limits (for example a 150 units/acre baseline in core areas, with bonuses that could raise that amount) and an absolute maximum height of 16 stories in the station core; it also prescribes an approach to parking that uses urban Institute of Transportation Engineers numbers with a 20% transit proximity discount.

Mark Alvarez of Corradino said the rewrite’s intent is predictable growth and “to direct density toward the infrastructure,” while offering bonuses for public benefits such as open space, affordable and workforce housing and building sustainability. The draft includes a pay-in-lieu option for bonuses; staff noted the current draft uses a placeholder $55 per square foot figure, though commissioners signaled interest in an introductory reduced rate to encourage early projects.

Residents, property owners and brokers filled much of the evening’s public comment period, pressing the commission to slow down and refine the rules for the Sunset Drive frontage and nearby blocks. Speakers raised three recurring concerns: that some Sunset Drive parcels are landlocked with no rear access and so cannot provide required parking without curb cuts on the street; that a proposed two‑story main‑street frontage with taller volumes set back behind it may not be physically or economically feasible on some shallow lots; and that a relatively high bonus fee could discourage redevelopment.

"We’re talking about a generational change to our main corridor," said a Sunset Drive property owner during the hearing. "Please do not rush this through in the final hour." Another commenter said a high pay‑in‑lieu number would simply keep owners from selling to redevelopers and could freeze reinvestment.

Commission discussion focused on several technical corrections and policy choices. Commissioners asked staff to: restore earlier mapping for two parcels south of 70th Street that workshop versions had designated for 16 stories; add administrative clarification so the city can determine the appropriate frontage for loading/parking access where properties face two "primary" streets; and study specific alternatives for Sunset Drive — including keeping a 4‑story envelope for the street or allowing a two‑story street face with taller volumes set back — plus targeted parking exemptions or solutions for the landlocked parcels.

On the bonuses and public‑benefit payment, the commission directed staff to model an introductory lower fee to encourage early movers (a working direction was $30 per square foot for a limited period transitioning to a longer‑term $50 per square foot figure, subject to further analysis and annual review), and to return with fiscal impact estimates and analysis of how much revenue would be available for city public benefits and infrastructure.

Rather than vote on final adoption, the commission remanded the draft back to the Planning Board for review of the directed changes at its Dec. 3 meeting, set a first‑reading schedule for the map and text on Dec. 10, and targeted final adoption — after required state transmittal/review — in mid‑February. The direction is intended to give the public, affected property owners and staff time to resolve mapping details and technical code edits before final action.

What’s next: staff will return revised text to the Planning Board on Dec. 3 and come back to the commission for first‑reading map action on Dec. 10. Commissioners said they want further analysis on parking demand, the bonus fee phasing, and a clear mechanics paper explaining how waivers, bonuses, and any transfer‑of‑development‑rights alternatives would work in practice.

The commission’s remand preserves the draft’s broad ambition — to channel density toward the transit station while providing design controls and public benefits — but pauses final adoption to address community concerns about Sunset Drive’s scale, parking access and the price of bonus floors.
