Coral Gables will take a major step toward establishing a new conservation tool on Wednesday, Nov. 19, when the Planning and Zoning Board reviews a proposal that would create the city’s first conservation-based Transfer of Development Rights (TDR) program. The meeting begins at 6 p.m. in Commission Chambers and follows the City Commission’s vote last month approving the measure on first reading.

The program would enable development rights to be shifted away from environmentally sensitive parcels—preserving them through permanent conservation easements—and redirected to areas that can accommodate additional density. It represents a structural change in how the city manages land preservation, environmental protection and long-term planning. The agenda also includes amendments affecting marine structures on the Mahi Canal, composite construction materials, recovery-residence definitions and sustainability certification.

Although technical in form, the items shape how the city balances growth and preservation across multiple neighborhoods, introducing new oversight to waterfront conditions, land management and building standards.

A conservation program designed to permanently protect sensitive land

The most significant proposal introduces a Conservation TDR system, a tool widely used in other municipalities but new to Coral Gables. Under the framework, owners of land designated as “sending areas” could transfer development rights to receiving sites elsewhere in the city, allowing sensitive parcels to remain protected in perpetuity.

According to the staff report, the city would require each sending parcel to record a Grant of Conservation Easement Agreement—a binding, permanent restriction that prevents future development and ensures that preserved land remains open space.

To qualify, a parcel must meet several environmental thresholds, including:

• A verified minimum 40 percent tree canopy,
• Documentation of native habitat,
• Review and confirmation by the city’s Greenspace Management division,
• Additional ecological assessments as required.

These standards narrow eligibility to parcels with demonstrated ecological value, signaling the city’s intention to direct the program toward meaningful conservation rather than general land banking.

The staff report also introduces an “ecological bonus,” allowing up to 15 percent additional TDR credits for sites with exceptional habitat quality verified by environmental professionals. This incentive creates a structured way to reward landowners whose properties provide broader ecological benefits.

Review of TDR applications would require recommendations from the Landscape Beautification Advisory Board, with the City Commission making final determinations through resolution. Receiving sites would record restrictive covenants to guarantee the permanent application of any transferred development rights. Approvals for those rights would expire after two years if unused.

Together, these provisions establish a rigorous framework for conservation transactions and give the city a mechanism for preserving sensitive land while offering property owners alternative economic value.

A structured system for valuing development rights

The program includes a detailed appraisal framework designed to standardize TDR valuation. The staff report outlines a formula requiring:

• Two independent appraisals establishing the fair market value of the sending parcel,
• Use of two comparable transactions to determine the unit value of TDR credits,
• A calculation that divides fair market value by unit value to identify total transferrable rights.

This procedure ensures transparency and reduces uncertainty for both landowners and receiving-site developers. It also introduces consistent economic expectations into what would otherwise be complex and individualized negotiations.

The report concludes that the program is consistent with the city’s Comprehensive Plan, particularly policies encouraging open space, environmental stewardship and sustainable growth.

Added oversight for marine structures along the Mahi Canal

Another amendment introduces new review requirements for docks, boat lifts and mooring structures along the Mahi Canal for properties within MF and MX zoning districts. The change does not prohibit these features, but it places them under a more formal evaluation process to ensure compatibility with environmental conditions, navigability and the visual character of the shoreline.

Because waterfront construction carries long-term impacts on both private and public access, the new review process reflects the city’s broader effort to regulate structures that contribute to congestion, scale disparities or view obstruction along the canal.

Updates to land-use standards and material rules

A separate zoning text amendment would allow the use of composite recycled materials for trellises, decks and walkways. The staff report notes that composite products have become common in contemporary construction and offer durability advantages over traditional wood. The update modernizes the list of permitted exterior materials while remaining consistent with Coral Gables’ architectural standards.

Another proposal revises definitions governing group residential homes, assisted-living facilities and Certified Recovery Residences. The changes bring local terminology in line with state requirements and clarify pathways for reviewing recovery-residence applications. These adjustments reflect increased statewide regulation and ensure that the city’s zoning code remains aligned with current law.

Expanded options for green-building compliance

The board will also consider an amendment that adds National Green Building Standard (NGBS) Silver as an approved pathway for meeting the city’s sustainability requirements. This gives architects and developers greater flexibility in satisfying green-building criteria while preserving the city’s environmental objectives.

Unlike changes that alter entitlements or development limits, the sustainability update broadens compliance options without affecting building size or intensity.

A turning point in how Coral Gables manages preservation

The Conservation TDR program stands out as the structural change with the deepest implications. If adopted at second reading, it would introduce a tool that permanently conserves land through binding easements while channeling density into appropriate areas. The program’s controls—eligibility thresholds, appraisal rigor, ecological bonuses and recorded covenants—reflect a conservation strategy built around long-term commitments rather than temporary restrictions.

For a city that balances historic neighborhoods, environmental resources and steady development pressure, the proposal marks a meaningful shift toward formalizing preservation as part of its zoning framework heading into 2026.
