Olongapo

In 1868, a Spanish military expedition was dispatched to study the possibility of relocating the Cavite Naval Station in Subic Bay due to its unhealthy conditions.

Spanish King Alfonso XII through a Royal Decree made Subic Bay (then called Subig) as Spain's stronghold in the Far East in 1884. Vice Admiral Juan Bautista de Antiquiera made Olongapo a settlement for the Spanish Navy.

On March 8, 1885, the Spanish Naval commission authorized the construction of the Arsenal in Olongapo. The Spanish planned to transform their naval station and the village of Olongapo into an island, safeguarding it from potential rebel attacks. The Spanish Navy Yard occupied the entire area east of the Spanish Gate. Employing Filipino labor, they did extensive dredging of the harbor and the inner basin and built a drainage canal. The canal served both to drain the swampy area around the yard and also to form a line of defense.

Within 10 years, the Spaniards had erected walls and markers to fence off the arsenal. They had shops and buildings erected. The Spanish government spent almost fifteen years developing the naval station. From higher naval commands, the order was sent to fortify Grande Island at the mouth of Subic Bay.{{cite web|url= http://www.subicbaypi.com/sub_stories_olongapostory.htm|title= The Olongapo Story}}{{cite web|url= http://olongapo-city-philippines.blogspot.com/2009/11/olongapo-city-barangay-and-history.html|title= Olongapo City Barangay and History|date= November 14, 2009}}{{cite web|url= http://www.olongapocity.gov.ph/History.html&client=firefox-a|title= History of Olongapo City}}{{dead link|date=February 2024|bot=medic}} In the meantime, during the Philippine Revolution, a fleet led by the Cuban-Filipino Admiral Vicente Catalan seized the naval base at Subic-Olongapo from the Spanish for the First Philippine Republic.

On May 1, 1898, the construction of the Spanish Administration Building was nearly complete when Admiral Dewey's flagship, {{USS|Olympia|C-6|6}}, led the Asiatic Fleet into Manila Bay. A detachment of Dewey's fleet bombarded the navy yard. Eventually, after the surrender, Spain relinquished all her rights in the Philippines to the United States. This marked the end of more than three hundred years of Spanish rule over the islands.

Realizing the tremendous importance of Olongapo as a naval facility, the U.S. Navy decided to keep the base in functioning order; US President Theodore Roosevelt, on November 9, 1901, by executive order, reserved the waters of Subic and some of the adjacent lands for naval purposes.

The naval station was widened and with the establishment of the American rule in the Philippines. American defenses in the islands were facilities left by the Spanish Navy which were taken over by the United States.

Olongapo grew in direct proportion to the growth of the naval station. More people came to live in Olongapo since the Navy offered employment. To most Filipinos during that time, it was a welcome change. The promise of a different kind of experience as shop workers and office help induced many young men to leave their farms and fishing boats to work in the Navy Yard. Others finding the lure of the sea irresistible joined the U.S. Navy.

Olongapo impressed its visitors as being one of the finest communities in the country. People passing through the town never failed to comment on its cleanliness and orderliness.{{cite web|url= http://olongapo-subic.com/olongapo_city_subic_bay_zambales_museum_history.htm|title= History of Subic Bay and Olongapo City|access-date= December 13, 2011|archive-url= https://web.archive.org/web/20120313035911/http://olongapo-subic.com/olongapo_city_subic_bay_zambales_museum_history.htm|archive-date= March 13, 2012|url-status= dead}}

When the war broke out in 1941, the old town was obliterated. Olongapo was twice destroyed.

On December 14, 1941, Japanese bombers attacked the Olongapo/Subic Bay area. Ten days later, the order was given to burn Subic Bay Naval Station and withdraw. Olongapo was set aflame by the Filipinos in anticipation of the Japanese arrival. The USS New York was scuttled in Subic Bay.[http://www.subicbaypi.com/subic_timeline40.htm Subic Bay History – 1940's]. Subicbaypi.com (April 8, 1942). Retrieved on July 28, 2013. When the American forces made a last-ditch stand on the Bataan peninsula, the Naval Station was abandoned and most of its facilities were burned before the Japanese came.

In 1945, Olongapo was again bombed, shelled and burned. Joint American and Philippine Commonwealth ground troops aided guerrilla fighters in liberating Olongapo from the Japanese forces. With the exceptions of the Station Chapel (the Olongapo Parish Church before the war) and the Spanish Gate, none of its former landmarks withstood the war. The general headquarters between the United States Army, Philippine Commonwealth Army & Philippine Constabulary were located in Olongapo during and after World War II, and were active until 1946 after operating against the Japanese for the liberation of Central Luzon.

In 1946, the Philippines was granted independence. Olongapo was one of the principal naval bases retained by the United States. The Navy started rebuilding the town after hostilities ceased. Olongapo was built on a new undeveloped site a couple of miles north of its former location. The prewar town site became part of the base.

The first few years after the war were difficult for the new town, as everything in the new Olongapo was damaged. There were no electric power and no drainage system. The water supply and sanitation facilities were inadequate, and streets were unpaved. Gradually, Olongapo evolved into a new community: new businesses were established, housing projects were planned and civic facilities were restored.

During the Korean War, the United States spent over {{US$|170 million}} to convert the base into the homeport of the Navy's Seventh Fleet, developing the Cubi Naval Air Station as the largest US installation of its kind in Asia. Naval authorities relocated the residence from the area of the former Public Works Center area to the intersection of what is now known as Rizal Avenue and Ramon Magsaysay Drive, and in the Barangays New Asinan and New Kalalake areas. Zoning of Olongapo was patterned after American practice where streets are constructed along straight lines. The magnitude of facilities construction in the Olongapo and Subic Bay area brought growth and prosperity to Olongapo. By 1956, migrants from nearby towns and provinces had swelled the population to 39,180.{{cite web|url= http://www.olongapocity.gov.ph/?page_id=219|title= World War II |work= Olongapo City Official Website}}

Unlike the rest of the Philippines which gained independence from the United States after World War II in 1946, Olongapo was governed as a part of the United States naval reservation. The Subic Bay Naval Base commanding officer was chairman of the Olongapo town council, school board, and hospital board. Olongapo's 60,000 Filipino residents paid taxes to the US Navy and those accused of crimes involving American servicemen were tried in US Navy courts. In July 1955, Manila mayor Arsenio Lacson announced that American service personnel accused of crimes in Manila would be tried in Philippine courts because of US Navy abuses of Filipinos in Olongapo.

On October 23, 1959, Olongapo was placed under martial law when Robert Grant, the American owner of an Olongapo auto parts store was killed and the US Navy declined to identify or try the Naval Supply Depot sentry who shot him.Anderson, Gerald Subic Bay from Magellan to Pinatubo: The History of the U.S. Naval Station Subic Bay Gerald Anderson (2009); {{ISBN|1441444521}} pp. 130–138

Olongapo was the last piece of Philippine territory surrendered by the United States to the country in the 1950s.{{cite web|url= http://info.worldbank.org/etools/docs/library/166856/UCMP/UCMP/Documents/olongapo.pdf|title= World Bank – Olongapo Profile}} On December 7, 1959, 56,000 acres of land with electrical, telephone and water utilities was relinquished to Philippine Secretary of Foreign Affairs Felixberto Serrano. The first mayor appointed was civic leader Ruben Geronimo. He was later succeeded by business entrepreneur Ildefonso Arriola.

Six years later, through the efforts of Representative Ramon Magsaysay Jr. in Congress and Senator Genaro Magsaysay in the Senate, President Ferdinand Marcos signed R.A. 4645. Olongapo was reconverted to a chartered city on June 1, 1966.{{cite web|url= http://members.tripod.com/Olongapo/legend.html|title= Olongapo City – Brief History}}

Olongapo was eventually upgraded to the status of a highly urbanized city (HUC) on December 7, 1983.{{citation needed|date=July 2022}}

In Olongapo, the continuation of the Vietnam war through this period meant the arrival of a constantly growing number of U.S. Sailors to adjacent U.S. Naval Base Subic Bay, which was headed by Manuel Ardonia.{{citation needed|date=June 2024}} The base was visited by 215 ships per month as the Vietnam War peaked in 1967, and it employed 15,000 Filipino civilians.

However, this also meant the rapid growth of prostitution in the areas around the base.Paz, J. C.

The economies of Olongapo and the nearby areas of Zambales evolved from a largely agricultural orientation at the end of the 1960s towards one built around sex industry related businesses such as bars by the mid-1970s. The nightclubs along Ramon Magsaysay Drive between the naval base main gate and Rizal Avenue were notoriously popular among the 4,225,000 servicemen visiting the base that year.Tucker, Spencer C.

{{main|1991 eruption of Mount Pinatubo}}

File:Ash from Mount Pinatubo covers NS Subic Bay.jpg

On June 15, 1991, Mount Pinatubo, {{convert|20|mi|km|abbr=off}} from the city, violently erupted with a force eight times greater than the May 1980 eruption of Mount St. Helens. Volcanic clouds blocked out the sun. Volcanic earthquakes and heavy muddy rain, as well as thunderstorms from a typhoon passing over Central Luzon, darkened the area for 36 hours in what would become known as "Black Saturday".{{cite web|url= http://www.olongapocity.gov.ph/?page_id=234|title= Twin Disasters- Olongapo City Official Website}}

This caused widespread damage to the United States facility and Olongapo City.

On September 16, 1991, the Senate leaders of the Philippines did not grant an extension of the existing RP-US Military Bases Agreement between the Republic of the Philippines and the United States, thus terminating the stay of the United States military in the Philippines.

File:US Flag lowered and Philippine flag raised during turnover of NS Subic Bay.jpg

Olongapo surged to national prominence during the incumbency of Mayor Richard Gordon, who, like his father before him, was against the departure of US military forces, yet lobbied for the turnover of the facility and its conversion into a freeport in 1992. Gordon spearheaded a volunteerism strategy to return an ailing economy to prosperity after Mount Pinatubo's eruption and the withdrawal of US forces. The strategy worked across all demographics and involved a strong corps of 8,000 volunteers who protected and preserved the abandoned base facilities from poachers. Gordon complemented this with an aggressive advocacy campaign to convert the area into a protected area and industrial zone. Later, he launched an aggressive international investment promotion which resulted in the accelerating the development of a prime industrial and tourism zone in the country, the Subic Bay Freeport Zone (SBFZ).

As the first chartered city and highly urbanized city in its province, Olongapo's reputation among Filipinos rose from being a "sin city" in the 1960s and 1970s into a "model city" in the 1980s, 1990s and 2000s.

A recent racial study showed that Angeles City, Pampanga; alongside Manila; and Olongapo, Zambales; was the locations of several concentrations of 250,000 Amerasians (Mixed American-Asians) who were born as a result of the American colonization of the Philippines and the presence of US bases in the country.{{Cite press release |title=200,000–250,000 or More Military Filipino Amerasians Alive Today in Republic of the Philippines according to USA-RP Joint Research Paper Finding |date=November 5, 2012 |url=http://amerasianresearch.org/releases/amerasianresearch-2012-09.pdf |access-date=July 11, 2016 |archive-url=https://web.archive.org/web/20131101212827/http://amerasianresearch.org/releases/amerasianresearch-2012-09.pdf |archive-date=November 1, 2013 |work=Amerasian Research Network, Ltd.}}{{#invoke:cite web||type=Academic paper presented at 9th International Conference on the Philippines (ICOPHIL-9) |last1=Kutschera |first1=P.

The city boasts its color-coded public transportation system which it has pioneered in the country. All public utility jeepneys and tricycles have its own color code depending on the district, zone or route that it is serving. Taxi services are also operated in the city but are limited.

Electricity services were formerly provided by the government-run Public Utilities Department (PUD) since the city was founded. However, in the late 2000s, the city faced debt in its electricity distribution costs amounting to P5 billion to power suppliers and threatened to cut the city from the Luzon power grid. Then Mayor James Gordon Jr. also attributed the crisis to low collection rate due to nonpayment or debts incurred by consumers, widespread energy theft and corruption in the PUD. The situation worsened because of interests imposed by Private Sector Assets and Liabilities Management Corp. (PSALM), the refusal of the Energy Regulatory Commission (ERC) to grant an increase in power rates, and the years of delay in the PUD's privatization.{{Cite news|url=http://newsinfo.inquirer.net/451401/olongapos-power-debt-burden|title=Olongapo's power debt burden|last=Gonzaga|first=Robert|newspaper=Philippine Daily Inquirer|access-date=July 3, 2016}}

In 2013, through Republic Act No. 10373, the PUD was sold for Php 610 million to Olongapo Electricity Distribution Company (OEDC), an affiliate of Cagayan Electric Power and Light Company (CEPALCO), which was given a 25-year franchise to take over the city's power distributor. The company has since upgraded the city's obsolete and dilapidated distribution network and has made significant improvements to the city's electricity services.{{Cite news|url=http://newsinfo.inquirer.net/371899/aquino-signs-law-on-olongapo-power-privatization|title=Aquino signs law on Olongapo power privatization|newspaper=Philippine Daily Inquirer|access-date=July 3, 2016}}

Water services are provided by Subic Water and Sewerage Company (also known as Subic Water. Not to be confused with Subic Water District (SWD), which is a different water distribution company serving the neighboring towns of Subic, Zambales.). In 2013, the city's shares in Subic Water has been sold to Maynilad Water Services Inc. (Maynilad) to continue modernizing the city's water utilities services.{{Cite news|work=Rappler|url=http://www.rappler.com/business/24592-olongapo-sells-10-of-subic-water-to-maynilad|title=Olongapo sells 10% of Subic Water to Maynilad|access-date=July 3, 2016}} In March 2016, this was reversed and the city has bought back its shares because the city wanted to have a representation in Subic Water because the city's constituents accounted for the majority of Subic Water's customers.
