Everglades Edge — Miami, Florida

Miami, an incorporated city of 446,663 residents according to the U.S. Census Bureau ACS 2023, occupies the southeastern tip of the Florida peninsula at the boundary where the urban fabric of Miami-Dade County presses against the eastern margin of the Everglades ecosystem. Everglades National Park — a UNESCO World Heritage Site and International Biosphere Reserve — begins approximately 30 miles southwest of downtown Miami, and the hydrological relationship between that protected landscape and the city is direct: the same freshwater that historically moved as a broad sheet across the peninsula once discharged through Miami-Dade County into Biscayne Bay, Miami's eastern boundary.

The city's founding in July 1896, documented by the City of Miami's official archive, coincided with a period of aggressive drainage and land reclamation that reshaped the Everglades over the following century. That transformation — encompassing drainage canals, flood control levees, and agricultural conversion — altered the regional hydrology and created the persistent tension between urban water supply, agricultural use, and ecological function that defines Miami's environmental context today. The Comprehensive Everglades Restoration Plan (CERP), authorized by Congress in 2000, represents the federal government's principal ongoing response to that history.

Miami's urban footprint rests on the Miami Rock Ridge, a formation of oolitic limestone that underlies the city and constitutes the primary freshwater aquifer system for the region. To the east lies Biscayne Bay, a shallow-water lagoon and federally designated Aquatic Preserve that forms part of the Atlantic Intracoastal Waterway. To the west and southwest, the eastern margin of the Everglades system begins almost immediately beyond the urban boundary. The Miami River bisects the urban core, flowing from the Everglades interior into Biscayne Bay near downtown — a corridor that once served as the principal conduit for freshwater moving from the interior wetlands to the coast.

The region's subtropical climate produces a pronounced wet season running from May through October and a dry season from November through April. This hydrological rhythm historically drove the Everglades' characteristic sheet flow: a slow, broad movement of freshwater southward across the low-relief limestone landscape, ultimately discharging into Florida Bay and Biscayne Bay. The Everglades Law Center documents that drainage and urban development since the late 19th century have substantially altered that sheet flow, severing much of the natural connection between the interior wetlands and the coastal estuaries that historically depended on a calibrated balance of fresh and salt water.

The development history of Miami is inseparable from the deliberate effort to drain and reclaim Everglades land. The Everglades Law Center's restoration timeline documents that Hamilton Disston's drainage efforts in the 1880s first demonstrated that Everglades land could be converted for agricultural and development use, stimulating broader interest in reclamation. This interest was formalized when Governor Napoleon Bonaparte Broward directed the creation of the Everglades Drainage District, authorizing the construction of drainage canals intended to reclaim wetland acreage for agricultural production.

The City of Miami's official archive places the city's formal incorporation on July 28, 1896, made possible by landowner Julia Tuttle and William and Mary Brickell, who persuaded Henry Flagler to extend his Florida East Coast Railway southward to Miami — railroad tracks reached the city by April 1896. That infrastructure arrival and the concurrent drainage works set in motion a pattern of urbanization that, over the following decades, replaced portions of the natural Everglades landscape with farms, roads, and eventually the second-largest metropolitan area in the southeastern United States.

By 1969, the ecological consequences of a century of drainage were pronounced enough to generate national attention. The Florida Museum of Natural History at the University of Florida documents that a proposed jetport in the Big Cypress Swamp that year drew widespread opposition and catalyzed federal and state environmental legislation. Florida's Water Resources Act — Chapter 373 of Florida Statutes — followed a water conference convened by Governor Reubin Askew in direct response to water shortages, saltwater intrusion into wellfields, and Everglades fires, according to the Everglades Law Center. That statute established the principle that Florida's water is held in public trust — a legal foundation that now underpins the state's water management framework.

Congress authorized the Comprehensive Everglades Restoration Plan (CERP) in 2000. The Florida Museum of Natural History describes CERP as the largest hydrological restoration project ever undertaken in the United States. Its central objective is to reverse key elements of the 20th-century drainage system — not by dismantling the urban and agricultural infrastructure that depends on it, but by redesigning water storage and conveyance to more closely replicate the natural timing, distribution, and volume of freshwater flows across the greater Everglades system.

The National Wildlife Federation describes CERP's core approach as capturing freshwater that currently flows unused to the ocean — diverted away from restoration areas by the existing canal and levee system — and redirecting that water to the ecosystems that depend on it. Among the downstream beneficiaries identified in the restoration framework are Florida Bay and the estuarine systems associated with Biscayne Bay, both of which depend on the balance of fresh and salt water that natural Everglades sheet flow historically provided.

For Miami, CERP's relevance is not only ecological but practical: the Biscayne Aquifer — the limestone formation beneath the city — is the region's primary source of drinking water, and its integrity is directly linked to the freshwater head maintained by the Everglades system to the west. Saltwater intrusion into that aquifer, identified by the Everglades Law Center as one of the triggers for Florida's 1970s water legislation, remains a documented concern for Miami-Dade County water managers.

Biscayne Bay, the shallow-water lagoon forming Miami's eastern boundary, is federally designated as an Aquatic Preserve and supports seagrass beds, manatee habitat, and a variety of marine species. The National Wildlife Federation identifies the bay as part of the broader estuarine system ecologically linked to the Everglades, noting that the health of Florida Bay and adjacent coastal waters is directly tied to the freshwater flows that CERP aims to restore.

Within the city, Coconut Grove — documented in the City of Miami's archive as one of the oldest continuously inhabited neighborhoods in Miami-Dade County — sits along Biscayne Bay's western shore. Miami City Hall, located at 3500 Pan American Drive in Coconut Grove, occupies a bayfront site. The Brickell neighborhood, named after William and Mary Brickell whose land donation enabled Flagler's railroad extension as documented in the City of Miami's official archive, lies just north of Coconut Grove along the bay — a geographic reminder that the city's founding geography was shaped by the same coastal and estuarine landscape now central to regional restoration discussions.

The Miami River, connecting the Everglades interior to Biscayne Bay through the urban core, functions simultaneously as a commercial waterway, a stormwater corridor, and the physical trace of a hydrological connection that predates the city. Its condition — particularly the quality of water it discharges into the bay — reflects the cumulative impact of the urban, agricultural, and natural systems upstream.

Miami is governed under a mayor-city commissioner plan, as documented by Ballotpedia, with a mayor serving as chief executive, a city manager overseeing day-to-day operations, and five commissioners elected from single-member districts. The city serves as the county seat of Miami-Dade County, and many environmental policy decisions affecting the Everglades edge — including water management, flood control infrastructure, and wellfield protection — are administered at the county level or through the South Florida Water Management District, a state agency that administers Chapter 373 of Florida Statutes.

The legislative framework governing water management in the region traces directly to the environmental crises of the late 1960s and early 1970s. Florida's Water Resources Act, enacted following Governor Askew's water conference as documented by the Everglades Law Center, established public trust principles for Florida's water supply — principles that now apply to the aquifer system beneath Miami. CERP, authorized federally in 2000, operates as a joint federal-state undertaking, with the U.S. Army Corps of Engineers and the South Florida Water Management District as the primary implementing agencies.

Mayor Francis Suarez, who served as Miami's 43rd mayor from 2017 until December 18, 2025, when he was term-limited out of office per Ballotpedia, delivered his final State of the City address in January 2025 at Miami Freedom Park — the site of a planned civic development on the former Melreese golf course, as reported by WLRN Public Radio. The city's fiscal position as of the 2024–2025 budget cycle showed more than $200 million in reserves, also reported by WLRN. A mayoral election to select Suarez's successor was scheduled for November 2025. The city government website is the canonical source for current officeholders as of mid-2026.
