# Pinellas County, Florida

Pinellas County (US: /pɪˈnɛləs/, pih-NEL-əss) is located on the west central coast of the U.S. state of Florida. As of the 2020 census, the population was 959,107, making it the seventh-most populous county in the state. It is also the most densely populated county in Florida, with 1,326 residents per square kilometre. The county is part of the Tampa–St. Petersburg–Clearwater Metropolitan Statistical Area. Clearwater is the county seat. St. Petersburg is the largest city in the county, as well as the largest city in Florida that is not a county seat.

## History
### Pre-European settlement

When Europeans first reached the Pinellas peninsula, the Tampa Bay area was inhabited by people of the Safety Harbor culture. The Safety Harbor culture area was divided into chiefdoms. One documented chiefdom in what is now Pinellas County was that of the Tocobaga, who occupied a town and large temple mound, the Safety Harbor site, overlooking the bay in what is now Safety Harbor. The modern site is protected and can be visited as part of the county's Philippe Park.

### Spanish and British Florida

During the early 16th century Spanish explorers discovered and slowly began exploring Florida, including Tampa Bay. In 1528 Pánfilo de Narváez landed in Pinellas, and 10 years later Hernando de Soto is thought to have explored the Tampa Bay area. By the early 18th century the Tocobaga had been virtually annihilated, having fallen victim to European diseases from which they had no immunity, as well as European conflicts. Later Spanish explorers named the area Punta Piñal (Spanish for "Point of Pines" or "Piney Point"). After trading hands multiple times between the British and the Spanish, Spain finally ceded Florida to the United States in 1821, and in 1823 the U.S. Army established Fort Brooke (later Tampa).

### Settlement of West Hillsborough

In 1834 much of west central Florida, including the Pinellas peninsula (then known simply as West Hillsborough), was organized as Hillsborough County. The very next year Odet Philippe, a French Huguenot from Charleston, South Carolina became the first permanent, non-native resident of the peninsula when he established a plantation near the site of the Tocobaga village in Safety Harbor. It was Philippe who first introduced both citrus culture and cigar-making to Florida.
Around the same time, the United States Army began construction of Fort Harrison, named after William Henry Harrison, as a rest post for soldiers from nearby Fort Brooke during the Second Seminole War. The new fort was located on a bluff overlooking Clear Water Harbor, which later became part of an early 20th-century residential development (now historic district) called Harbor Oaks. University of South Florida archaeologists excavated the site in 1977 after Alfred C. Wyllie discovered an underground ammunition bunker while digging a swimming pool on his estate. Clearwater would later become the first organized community on the peninsula as well as the site of its first post office.
The Armed Occupation Act, passed in 1842, encouraged further settlement of Pinellas, like all of Florida, by offering 160 acres (0.65 km$^2$) to anyone who would bear arms and cultivate the land. Pioneer families like the Booths, the Coachmans, the Marstons, and the McMullens established homesteads in the area in the years following, planting more citrus groves and raising cattle. During the American Civil War, many residents fought for the Confederate States of America. Brothers James and Daniel McMullen were members of the Confederate Cow Cavalry, driving Florida cattle to Georgia and the Carolinas to help sustain the war effort. John W. Marston served in the 9th Florida Regiment as a part of the Appomattox Campaign. Many other residents served in other capacities. Otherwise the peninsula had virtually no significance during the war, and the war largely passed the area by.
On September 27, 1848, a strong hurricane struck the West Coast of Florida. It separated the barrier island on the coast and created a waterway known today as John's Pass. John Levique, along with Joseph Silva, was the one who discovered it and named it after himself and is now a federally owned canal.
Tarpon Springs became West Hillsborough's first incorporated city in 1887, and in 1888 the Orange Belt Railway was extended into the southern portion of the peninsula. Railroad owner Peter Demens named the town that grew near the railroad's terminus St. Petersburg in honor of his hometown. The town would incorporate in 1892. Other major towns in the county incorporated during this time were Clearwater (1891), Dunedin (1899), and Largo (1905).
Construction of Fort De Soto, on Mullet Key facing the mouth of Tampa Bay, was begun in 1898 during the Spanish–American War to protect Tampa Bay from potential invading forces. The fort, a subpost of Fort Dade on adjacent Egmont Key (which lies in the mouth of Tampa Bay), was equipped with artillery and mortar batteries.

### Birth of Pinellas County

Even into the early years of the 20th century, West Hillsborough had no paved roads, and transportation posed a major challenge. A trip to the county seat, across the bay in Tampa, was generally an overnight affair and the automobiles that existed on the peninsula at that time would frequently become bogged down in the muck after rainstorms. Angry at what was perceived as neglect by the county government, residents of Pinellas began a push to secede from Hillsborough. They succeeded, and on January 1, 1912, Pinellas County came into being. The peninsula, along with a small part of the mainland were incorporated into the new county.

### Land boom and prohibition

Aviation history was made in St. Petersburg on January 1, 1914, when Tony Jannus made the world's first scheduled commercial airline flight with the St. Petersburg–Tampa Airboat Line from St. Petersburg to Tampa. The popular open-air St. Petersburg concert venue Jannus Live (formerly known as Jannus Landing) memorializes the flight.
The early 1920s saw the beginning of a land boom in much of Florida, including Pinellas. During this period municipalities issued a large number of bonds to keep pace with the needed infrastructure, such as roads and bridges. The travel time to Tampa was cut in half—from 43 to 19 miles (69 to 31 km)—by the opening of the Gandy Bridge in 1924, along the same route Jannus' airline used. It was the longest automobile toll bridge in the world at the time.
Prohibition was unpopular in the area and the peninsula's inlets and islands were used by rum-runners bringing in liquor from Cuba. Others distilled moonshine in the county's still plentiful woods.

### Great Depression and World War II

As was the case in much of Florida, the Great Depression came early to Pinellas with the collapse of the real estate boom in 1926. Local economies came into severe difficulties, and by 1930, St. Petersburg defaulted on its bonds. Only after World War II would significant growth return to the area. During the war, the area's tourist industry collapsed, but thousands of recruits came to the area when the U.S. military decided to use the area for training. Area hotels became barracks. The Vinoy Park Hotel was used as an Army training school. The area's women and girls participated in the war effort as well. Hundreds of girls from the area's most prominent families formed a group called the Bomb-a-Dears, holding dances, socializing with recruits, and selling war bonds. After the war many of these same soldiers remembered their wartime experience in Pinellas well, and returned as tourists or residents.

### Recent history

With the end of the Second World War, Pinellas would enter another period of rapid growth and development. In 1954 the original span of the Sunshine Skyway Bridge was opened, replacing earlier ferry service. By 1957 Clearwater was America's fastest growing city.
Tragedy struck on May 9, 1980, when the southbound span of the original Sunshine Skyway Bridge was struck by the freighter MV Summit Venture during a storm, sending over 1,200 feet (370 m) of the bridge plummeting into Tampa Bay. The collision caused seven personal vehicles and a Greyhound bus to fall 150 feet (46 m) into the water, killing 35 people. The new bridge opened in 1987 and has since been listed as number 3 of the "Top 10 Bridges" in the World by the Travel Channel.
The county operates a 21-acre (8.5 ha) living history museum called Heritage Village containing more than 28 historic structures, some dating back to the 19th century, where visitors can experience what life was once like in Pinellas.
Pinellas County celebrated 100 years of existence on January 1, 2012.

## Geography

According to the U.S. Census Bureau, the county has a total area of 608 square miles (1,570 km$^2$), of which 274 square miles (710 km$^2$) is land and 334 square miles (870 km$^2$) (55.0%) is water. It is the second-smallest county in Florida by land area, larger than only Union County. Pinellas forms a peninsula bounded on the west by the Gulf of Mexico and on the south and east by Tampa Bay. It is 38 miles (61 km) long and 15 miles (24 km) wide at its broadest point, with 587 miles (945 km) of coastline.

### Physical geography

Elevation in the county ranges from mean sea level to its highest natural point of 110 feet (34 m) near the intersection of SR 580 and Countryside Blvd. in Clearwater. Due to its small size and high population, by the early 21st century Pinellas County has been mostly built out, with very little developable land left available. The county has maintained a fairly large system of parks and preserves that provide residents and visitors retreat from the city and a glimpse of the peninsula's original state.
Geologically, Pinellas is underlain by a series of limestone formations, the Hawthorne limestone and the Tampa limestone. The limestone is porous and stores a large quantity of water. The Hawthorne formation forms a prominent ridge down the spine of the county, from east of Dunedin, south to the Walsingham area and east towards St. Petersburg.
The 35 miles of beaches and dunes which make up the county's 11 barrier islands provide habitat for coastal species, serve as critical storm protection for the inland communities, and form the basis of the area's thriving tourism industry. The islands are dynamic, with wave action building some islands further up, eroding others, and forming entirely new islands over time. Though hurricanes are infrequent on this part of Florida's coast, they have had a major impact on the islands, with the Hurricane of 1848 forming John's Pass between Madeira Beach and Treasure Island, a hurricane in 1921 creating Hurricane Pass and cleaving Hog Island into Honeymoon and Caladesi Islands, and 1985's Hurricane Elena sealing Dunedin Pass to join Caladesi with Clearwater Beach.
Between the barrier islands and the peninsula are several bodies of water, through which traverses a section of the Gulf Intracoastal Waterway. From north to south they are: St. Joseph Sound between the islands and Dunedin, Clearwater Harbor between Clearwater and Clearwater Beach, and Boca Ciega Bay in the southern third of the county. Connecting Clearwater Harbor to Boca Ciega Bay is a thin, approximately 3.5-mile (5.6 km) stretch of water known as The Narrows, which runs next to the town of Indian Shores.
Extending from northeastern Boca Ciega Bay, Long Bayou separates Seminole from St. Petersburg near Bay Pines. Long Bayou once extended significantly farther up the peninsula until the northern portion was sealed off to create Lake Seminole. Extending further still from Long Bayou, the Cross Bayou Canal traverses the peninsula, crossing Pinellas Park in a northeasterly direction before emptying into Tampa Bay on the northwest side of St. Pete–Clearwater International Airport.

## Ecosystems
### Plant life

Several natural communities exist within the county, including areas of freshwater wetlands (dominated by bald cypresses and ferns), coastal mangrove swamps, sporadic hardwood hammocks (dominated by laurel oaks and live oaks, cabbage palms, and southern magnolias), low-lying, poorly drained pine flatwoods (dominated by longleaf pines and saw palmettos), and well-drained, upland sandhills (dominated by longleaf pines and turkey oaks) and sand pine scrub (dominated by sand pines, saw palmettos, and various oaks). Offshore ecosystems include the Tampa Bay estuary and numerous gulf seagrass beds. The county also maintains several artificial reefs.

### Animal life

Numerous bird species can be sighted in Pinellas, either as permanent residents or during the winter migration, including wading birds like great blue herons, egrets, white ibises and roseate spoonbills, aquatic birds like brown pelicans, white pelicans, and cormorants, numerous species of shorebirds, and very-common birds like seagulls and passerines like the blue jay, mockingbird, and crow. Ospreys are a commonly seen bird-of-prey, with other birds of prey like turkey vultures, red tailed hawks, great horned owls, screech owls, barn owls, and bald eagles, among others, seen as well.
Gopher tortoises are found in many areas, the burrows they dig making them a keystone species. Coyotes, though often associated with the American West, are native-to and can be found in Pinellas. White-tailed deer, wild turkeys, bobcats, otters, and alligators can be found in the county as well.
Sea turtles nest on the shores or Pinellas' barrier islands and have been threatened by development. Offshore, dolphins, sharks, and manatees are numerous as well, while closer inshore stingrays are a common sight, leading those in-the-know to do the "stingray shuffle" (shuffling up the sand to scare nearby stingrays off) when entering gulf waters. Species of fish commonly caught in the waters surrounding the county include spotted seatrout, red drum or redfish, snook, pompano, sheepshead, Spanish mackerel, grouper, mullet, flounder, kingfish, and tarpon.

### Invasive species

Like much of Florida, Pinellas County is home to several invasive species that propagate easily outside their (and their natural predators') native range. Examples of commonly seen invasives include Brazilian pepper, water hyacinth, Australian pine, melaleuca and air potato. These species are considered serious pests, and varying methods have been tried to eradicate them. Examples of invasive animals include the wild boar, which poses significant health and agricultural problems in Florida and can sometimes be found in Pinellas, and the monk parakeet, small flocks of which can sometimes be seen in flight or building nests on electrical poles or telecommunications towers. There is also a large flock of feral peacocks residing in St. Petersburg's Jungle Terrace, Jungle Prada and Disston Heights neighborhoods.
Pinellas gained some national attention as the home of the Mystery Monkey of Tampa Bay, a non-native, feral rhesus macaque that had been on the loose for approximately three years in the south of the county. No one was sure where the monkey came from, and a Facebook page set up for the monkey had over 84,000 likes (as of October 2012). The monkey was the subject of a sketch on the March 11, 2010, episode of the Colbert Report. As of February 2012, the monkey had apparently taken up semi-permanent residence behind a family's home at an undisclosed location in St. Petersburg, according to the Tampa Bay Times. Efforts to capture the monkey were reignited after it reportedly bit a woman living near where it had taken up residence, and the monkey was captured in late October 2012 and eventually was sent to live at Dade City's Wild Things, a 22-acre (8.9 ha) zoo north of Tampa.

## Climate

Pinellas, like the rest of the Tampa Bay area, has a humid subtropical climate, resulting in warm, humid summers with frequent thunderstorms, and drier winters. Pinellas County's geographic position- lying on a peninsula between Tampa Bay and the Gulf of Mexico introduces large amounts of humidity into the atmosphere and serves to moderate temperatures. The geography of the peninsula also causes some variance in the county's average temperatures. St. Petersburg, further south on the peninsula, tends to have warmer daily average lows (by about 3 degrees) than areas such as Dunedin and Palm Harbor further north, though daily highs are very close. The north of the county also has fewer overall days of rain, but higher total annual precipitation when measured in inches, the county's south being prone to shorter, more frequent thunderstorms especially in the late summer.
Freezing temperatures occur only every 2–3 years, with freezing precipitation occurring extremely rarely. Springs are usually short, mild, and dry, with occasional late-season cold fronts. Summertime weather is very consistent, with highs in the low 90s °F (around 32 °C), lows in the mid-70s °F (around 24 °C), accompanied by high humidity and an almost daily chance of afternoon thundershowers. The area experiences significant rainfall during its summer months (approximately May through October), with nearly two-thirds of annual precipitation falling between the months of June and September. The area is occasionally affected by tropical storms and hurricanes, but has not suffered a direct hit since 1921. Fall, like spring, is usually mild and dry, with the hurricane season extending through November and sometimes affecting the area.
Many portions of south Pinellas, especially near the bay and gulf, have tropical microclimates. Tropical trees such as coconut palms and royal palms and fruit trees like mangoes grow very well in these microclimates.

In national politics, Pinellas County, was one of the first areas of Florida to break from the Solid South and elect Republicans to public office. Riding on the coattails of Herbert Hoover's victory in the 1928 election, Albert R. Welsh was elected to the Florida Senate and Kenneth W. Kerr to the Florida House of Representatives. In that same election, Gladstone R. Beattie, became the Pinellas County Sheriff and first Republican sheriff in Florida since Reconstruction, and Harry R. Hewitt became the Pinellas County Judge and the first Republican county judge in Florida. In 1951, Pinellas was the first county to send a majority-Republican delegation to the Florida House of Representatives in the twentieth-century.
From 1948 to 1988, it went Republican in every presidential election except Lyndon Johnson's 44-state landslide of 1964. However, for the last quarter-century, as part of the I-4 Corridor stretching from Tampa Bay to Orlando, Florida, it has been a powerful swing county in one of the nation's most critical swing states. Voter registration is almost tied, with Republicans having a small plurality of registered voters. It is closely divided between predominantly liberal St. Petersburg and its predominantly suburban and conservative north and beaches. Due in part to the more populated southern portion around St. Petersburg, it has supported a Democrat for president in all but three elections since 1992. The brand of Republicanism in Pinellas County has traditionally been a moderate one, so the county has become friendlier to Democrats as a result of the national GOP having shifted right.
In 2000, Al Gore became the first Democrat to win a majority of the county's vote since 1964, and only the second since Franklin D. Roosevelt. In 2004, Pinellas County swung the other way when George W. Bush carried the county by a narrow plurality of 49.56% (225,686 votes), with John Kerry following closely behind with 49.51% (225,460 votes)—a margin of just 226 votes. In the 2012 Presidential Election, Barack Obama won Pinellas with 52% of the vote (239,104 votes) to Mitt Romney's 46.5% (213,258 votes), slightly narrower than Obama's 2008 election results in Pinellas of 53% (248,299 votes) to John McCain's 45% (210,066 votes). Republican victories in the county since Bush in 1988 have been narrow pluralities. The exception to this is Donald Trump in 2024, who won the county with nearly 52% of the vote.
The county is considered a bellwether politically.
In the 2012 U.S. Senate election, Pinellas voters helped re-elect U.S. Senator Bill Nelson over challenger Connie Mack IV with 59% of the vote, greater than his statewide average of 55%. In the 2010 U.S. Senate election, Pinellas was one of only four Florida counties won by outgoing Republican Governor Charlie Crist, a St. Petersburg native, who won 42% of Pinellas voters running as an Independent in a three-way race with Republican nominee (and eventual winner) Marco Rubio and former Democratic U.S. Representative Kendrick Meek, who won 37% and 16.8% of the Pinellas vote, respectively. Statewide, Rubio won almost 49% of the vote to Crist's 29.7% and Meek's 20% in a highly polarized election that would witness Crist depart from the Republican Party and eventually become a Democrat.
In the House of Representatives, most of Pinellas is represented by Republican Anna Paulina Luna of the 13th district. Most of the city of St. Petersburg, including the most Democratic parts of Pinellas, is represented by Democrat Kathy Castor of the 14th district, which spans the Tampa Bay. The way this map has been drawn has been considered an example of a pro-Republican gerrymander, given the previous Democratic lean of the 13th.
In state politics, portions of Pinellas are represented in the Florida Senate by Democratic State Senator Darryl Rouson (District 16) and Republican State Senators Nick DiCeglie (District 18) and Ed Hooper (District 21). In the Florida House parts of the county are represented by Republicans Adam Anderson (District 57-Palm Harbor, Tarpon Springs), Kimberly Berfield (District 58-Clearwater), Berny Jacques (District 59-Largo), and Linda Chaney (District 59), as well as Democrat Lindsay Cross (District 60- Pinellas Park). Portions of St. Pete are also included in District 62, represented by Michele Rayner-Goolsby.

### Railroads

The CSX railroad company operates the Clearwater Subdivision in Pinellas County, made up of segments of branch lines of the former Atlantic Coast Line Railroad and the Seaboard Air Line Railroad. Beginning in Tampa, the line has daily freight rail traffic through Oldsmar, Safety Harbor, Clearwater, Largo, Pinellas Park, and into St. Petersburg. Regularly-scheduled passenger rail services in Pinellas County ended on February 1, 1984, when Amtrak discontinued its rail operations in the county, and the last passenger rail service in the county of any kind, a series of special excursion runs between Tarpon Springs and Dunedin, occurred on March 8, 1987. CSX owned the last remaining trackage in downtown St. Petersburg until March 2008 when it, along with the remaining trackage south of Central Avenue and east of 34th Street South, began to be dismantled. That right-of-way, as well as the right-of-way of several other former CSX railroad lines in the county beginning in the 1990s, was converted into a section of the Pinellas Trail.
As of 2012, proposals were being developed by community leaders for a light rail system which would connect the regional core cities of Clearwater, St. Petersburg, and Tampa. The proposal, which has won the backing of the Clearwater and St. Petersburg City Councils would rely on a 1% sales tax and would have to go before voters for approval.
