History


Spanish colonial era

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 Alfonso XII (Alfonso Francisco de Asís Fernando Pío Juan María de la Concepción Gregorio Pelayo de Borbón y Borbón; 28 November 185725 November 1885), also known as ''El Pacificador'' (Spanish: the Peacemaker), was King of Spain from 29 D ...
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. In the meantime, during the Philippine Revolution, a fleet led by the Cuban-Filipino Admiral

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

, 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.


Japanese occupation

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 ''

Postwar Era

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 Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was s ...
, the United States spent over 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.

Marcos dictatorship era

The beginning months of the 1970s marked a period of turmoil and change in the Philippines, as well as in Olongapo and Zambales. During his bid to be the first Philippine president to be re-elected for a second term, Ferdinand Marcos launched an unprecedented number of foreign debt-funded public works projects. This caused the Philippine economy to take a sudden downwards turn known as the

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. The base was visited by 215 ships per month as the

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.

. 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". 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.


Contemporary era

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

(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.

Public Utilities


Electricity

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. 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.


Water

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. 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.
