Plaquemines Parish, Louisiana

Because Plaquemines Parish encompasses the last 70 miles (110 km) of the Mississippi River before it reaches the Gulf of Mexico, it is the site of several oil refineries, which rely on the shipping lanes for moving their product. The Mississippi River Delta of Plaquemines is also a base for assistance to offshore oil rigs. Plaquemines Parish was the first place in the United States where shippers used a container for cargo in foreign trade. The area is also known for having the southernmost point in Louisiana, at just under 29 degrees north.

The August 1901 Hurricane caused damage, including 4 feet of water in Buras.[7]

The Great Hurricane of 1915 devastated much of the parish, with multiple levee breaches on both sides of the Mississippi, a 12-foot storm surge, and hundreds of deaths. Homelessness was widespread, and many people were reduced to starvation until charitable aid arrived.[8] The old Parish Courthouse in Pointe à la Hache was among the many buildings destroyed in the storm, but a new one was completed within the year.

In the early 1900s, Plaquemines was an exporter of citrus. Farmers used the railroads and the Mississippi to ship the large annual harvest to markets. Commercial fisheries, especially for oysters, have been important in the parish economy.

From 1924 to 1969, Plaquemines and St. Bernard parishes were effectively the domain of the Democratic political boss Leander Perez, who established a strong hold over the area.[9] He was notorious for fixing elections and enforcing strict racial segregation. Upon his death, his sons Leander Perez, Jr., and Chalin O. Perez were elected as the dominant political figures of the parish as district attorney and parish president, respectively. Interpersonal feuding weakened the family's hold on power. After another decade, by 1980 political opponents had begun to win local elections.[9]

In 1969, Hurricane Camille devastated portions of Plaquemines Parish. Storm surge over 10 feet, winds over 100 miles per hour, and peak pressure at 941 hPa devastated Buras, Louisiana, Venice, Louisiana, and many more towns and cities.

During the Great Mississippi Flood of 1927, city and state leaders used dynamite to breach a levee at Caernarvon, thirteen miles (21 km) below Canal Street, in order to save the city of New Orleans from flooding. This action resulted in the flooding of much of the less populated St. Bernard and Plaquemines parishes, causing widespread destruction to agriculture and housing.

The Civil Rights struggle for African-Americans to become registered voters in Plaquemines Parish begin in October 1946, under the guidance of Dr. Rev. Percy Murphy Griffin. With the aid of Attorneys Earl Amedee and Louis Berry from New Orleans, Griffin and twenty-six African-Americans from Plaquemines Parish organized the Plaquemines Parish Civil and Political Organization, Inc., to fight racial barriers established by Perez. In the summer of 1953, the group organized a voter registration drive for African Americans. In 1954, Irene Griffin became the first black woman to register to vote in the parish.[10] The organization filed class-action suits against Leander Perez and in 1953, several African-Americans became registered voters in Plaquemines Parish. In 1966, the organization led the fight to integrate public schools. The movement also worked to get Seymourville and another small community included within the parish boundaries; the city had sought to exclude these majority-black communities to prevent black votes from being counted.[11] The Civil Rights Act of 1964 ended legal segregation, and the Voting Rights Act of 1965 authorized federal oversight and enforcement of voter registration and elections in jurisdictions with historic under-representation of minority elements of the population. After 1965, African Americans in Louisiana began full participation in Louisiana politics.

In 1965, Hurricane Betsy flooded many buildings, including the parish courthouse, and caused nine deaths. Leander Perez sealed off the parish to control the distribution of state assistance.[12]

It is estimated that without significant human intervention, Plaquemines Parish will lose 55% of its current land to rising sea levels over the next 50 years.[13]

Hurricane Katrina struck Louisiana on August 29, 2005, resulting in one of the worst disasters in United States history; it severely damaged all of southeast Louisiana. Martial law was not declared in Plaquemines, contrary to many media reports, as no such term exists in Louisiana state law.[14] No place escaped without some damage, while most of Plaquemines, Orleans, and neighboring St. Bernard parishes were severely affected. The towns of Pointe à la Hache, Port Sulphur, Buras, Triumph, Empire, Boothville, Phoenix, and Venice suffered catastrophic damage.

Amid heavy rains accompanied by hurricane-force winds in excess of 120 mph (190 km/h) at initial landfall (with a Category 5 storm surge), the levees failed and broke. The storm surge which flowed in was more than 20 feet (6.1 m) high. Although a majority of the populace had complied with mandatory state evacuation orders, some did not, possibly because they were not able to. At least three people died.

Non-denominational and interdenominational congregationalist, Bible, and United and Uniting churches were the second-largest Christian group in the parish with 1,190 members.[29] The non/inter-denominational churches reflected the increase among ecumenical and independent churches throughout Louisiana since the 2020 religion census by the Association of Religion Data Archives.

Oil and gas continue to play a dominant role in the Plaquemines economy; however, there is a growing policy and resource trend in favor of renewable resources. The Parish government is working with public and private partners to invest in renewable energy, including hydrokinetic energy and wind energy. Plaquemines has a huge potential for hydrokinetic energy sites along deep bends in the Mississippi River. The flow of the river is 470,000 cubic feet per second at the Head of Passes during normal river stages and 1,250,000 during peak times.[33] Tidal turbines would be placed in deep bends of the river below seagoing and barge traffic. The turbines would also be located below the usual migrating routes of fish. Four companies intending to install turbines are in the regulatory and permitting stages.[34]

The potential installation of wind turbines at the mouth of the Mississippi River is also being considered.[35] The capacity of a wind source to produce energy is generally measured by Wind Power Density. Wind Power Densities are divided into seven Wind Power Classes. According to the American Wind Energy Association, Plaquemines has winds in specified areas that fall into a Wind Power Class of seven, which makes the Parish a particularly attractive location for wind turbine investment. Wind turbines would likely be placed at the mouth of the Mississippi, where winds are the strongest. Wind Energy Systems Technology has proposed to build a 12.5 MV wind farm in Barataria Bay off the coast of Plaquemines Parish. The energy would be sent to Myrtle Gove through an underground cable. The wind farm would be supplemented with natural gas turbines when wind speeds are either not sufficient or too robust to supply power. A similar proposal is being considered for the southern portion of the Parish.
