Barangay New Asinan is located right outside the main entrance of the Subic Bay Freeport Zone, the former seat of the US Naval Base in the City. It is bounded to the North by a drainage channel that separates the Subic Bay Freeport from Barangay Asinan and the rest of the City proper, to the East by Barangay Pag-asa, to the West by Barangay Banicain, and West Tapinac, and to the South by Barangay East Tapinac. It is divided into nine (9) puroks covering residential and commercial areas.Topography, Slope and Soil Classification
Barangay New Asinan is one of the smallest Barangays in the City of Olongapo but also one of the busiest being a commercial business district. It has a total land area of 23.98 hectares of which 62.71% is built up area, or 15.04 hectares.
While Olongapo City, as a whole, is characterized by rolling to steep and rugged topography (2001 CLUP, Olongapo City), Barangay New Asinan is generally sloping from of 0 to 2.5%, which makes it attractive for business establishments and for residential sites. The area was assessed as good for urban uses. In the general land use, it is classified as built-up area.
In the basic soil map, soil is classified as San Manuel Silt Loam. The area is subject to occasional flooding. In the hydrologic map, the area is not excluding water at greater depth. Pyroclastic rocks make up the thick confined aquifers. Permeability, a property that can be penetrated by liquid, is low to very low.
There are properties of the soils which make it suitable for diversified crops. The soil is highly suitable for rice crops and tree crops.
Barangay Banicain is geographically located at western part of the city, bounded by West Tapinac, Barangay Asinan, Drainage Channel (boundary between Olongapo City anf Subic Bay Freeport Zone) at the south, on the north by Kalaklan River, on the east by Barangay Kababae. It is the edge or forefront barangay in the west side of Olongapo City. It is purely a residential area and small establishments along Rizal Avenue. Because of its proximity to the Subic bay Freeport, Migrants and transients who are working inside the economic zone are proffered to live in the place.
Barretto is approximately 7 kilometers north of Olongapo City proper and the Subic Bay Freeport Zone. It is bounded in the North by Barangay Sto. Tomas and Barangay San Isidro, both in the Municipality of Subic, Zambales; in the East by Barangay Kalaklan, Kalaklan Ridge and Barangay Gordon Heights. In the West it is bounded by Barangay Matain of Municipality of Subic and in the south is Subic Bay. The Barangay local government estimates that 40% of the land area is generally flat and around 60% is sloping — undulating to mountainous.
Stretching in the whole southern part of the Barangay is Barretto’s primary natural asset, the Subic Bay’s beach. Aside from providing environmentally fresh air from the bay, it propels the Barangay’s economic life.Land Use and Classification
Barretto has a total of 495.70 hectares based on the City Planning and Development Office data. It accounts to 6.71% of the total land area of the barangays in the City and 2.69% of the total land area of the City. The barangay local government estimates that about 45% of the land area is residential, 25% is forestland, 15% is tourism-reserved, 10% is commercial, and the remaining 5% is institutional. The City Assessor’s Office on the other hand, accounts the actual land use in the Barangay at a figure of 582.1 hectares, higher by 86.28 hectares which is worth considering by both the City government and the Barangay. With this figure, 96% of the total is for residential use and only 4% is for commercial use.
Barangay East Bajac-Bajac is geographically located south-east of Olongapo City. Bounded in the South by a hill naturally separating the City and the barangay from Subic Bay Freeport Zone (SBFZ); in the East is Barangay Old Cabalan; in the North is West Bajac-Bajac, and in the West is Barangay East Tapinac. The City’s largest and main commercial strip, the Rizal Avenue, runs adjacent to the west boundary of the Barangay. It is the Central Business District of the City. The sloping areas are located at Purok 11 to 15. These are places of Little Baguio and Upper Sibol. It is estimated that 15% of the total land area is sloping and is under the classification of alienable and disposable (A&D). The slopes are densely populated with a mix of concrete and makeshift structures. The local government has consistently warned informal settlers who had stubbornly settled at the cliff portion of the hill to vacate the areas classified as landslide-prone area.Land area and land classification
Barangay East Bajac Bajac has a total land area of 93.5 hectares based on the City’s Land Use Section records. Assessors’ Office, on the other hand, considered the land area to be at 97.675 hectares (CAO 2006 report). Nevertheless, the land areas in the Barangay are all considered as built-up area and comprise 1.36% to 1.42% of the total 6,887.52 hectares of the built-up area of the City. The barangay is subdivided into 14 political administrative areas which are called puroks. There are only three (3) classifications of land in the area: Institutional, Commercial, and Residential. Institutional is defined as a sector that covers the major public and semi-public uses like educational, cultural, religious, health, protective, and government services. Institutional in Barangay East Bajac Bajac is a small portion and is confined in Purok 1, the St Joseph College and Roman Catholic Church, a Mosque, Virgen de los a Remedios College, Metro Subic College, Celtech, East Bajac Bajac Elementary School, three (3) Day Care Centers and the Barangay Hall.

Commercial strip can be located along 18th Street to Harris Street of Purok 2 and 3 and along 20th Street of Purok 4, 5, and 7. Residential, on the other hand, is for dwelling purposes. It comprises the majority of the land area. This can be found in Purok 2, 3, 4, 5, 7, 8, 9, part of Purok 10 and the whole of Purok 12, 13 and 14.
Barangay East Tapinac is one of the progressive barangay, because of its geographical and strategic location proximity to the city proper and to Subic Bay Freeport Zone-SBMA that generate employments.

At the west side is Kalaklan Ridge stretching to the north accommodating the barangay’s last village, Purok 13 and at the south of the barangay is Barangay Mabayuan.
The relative vast upland and water formations and vegetation is perceptible once in the barangay. It is worthy to note the need to have an inventory of topographic, local endemic flora, fauna thriving in the area and land formations. These are the natural assets of the Barangay Gordon Heights which is a potential resource generation asset for the local government if innovatively harnessed.
Barangay Kalaklan is located at the north-western part of Olongapo City. It is bounded at the eastern part by the banks of Kalaklan River adjacent of which are Barangays West Tapinac, Kababae, New Banicain and the part of West Bajac Bajac. In the northeastern part is Barangay Mabayuan, and at the north is Barangay Barretto. The western side is the coast of Subic Bay. At the middle of the barangay is the sloping land area of Kalaklan Ridge estimated to be at 1,000 feet above sea level.
Barangay Kalaklan has a total land area of 750.32 hectares or 7,503,200 square meters subdivided into 6 Puroks. The land area includes almost half of the Kalaklan Ridge from the southern tip up to the northern highland boundaries of the barangay.Land classification
The barangay’s land area is classified with residential, commercial, institutional, tourism, parks, and forest area. The land use map of the barangay indicates that almost half of its land area is classified as forest. (CLUP 2001) The other half is residential.
The actual use of the land is different. The areas along the national highway traversing from the Kalaklan Bridge to the coastal area are cluttered up with commercial establishments. The classified forest area of the ridge is encroached with residential communities which are part of the jurisdiction of the purok. The tourism area is likewise encroached.
Based on the City Assessors’ records, taxable land accounts only to a total of 3,104,022.80 square meters or 41.37% of the total land area of the barangay. This means that the rest of the land area are not open for any human activity by reason of land use regulations. Residential area comprises almost all of the taxable area at 91.99% or 285.53 hectares.
There are no local inventory of flora and fauna in the barangay. Though for the past few years, sightings of migrating egrets were seen regularly in the Kalaklan Ridge and Kalaklan River. There were neither protection and conservation program but the area is currently being considered for future development projects which are all in a conceptual stage.
Barangay Mabayuan has a total land area of 273.26 hectares and is geographically located at the inner northwestern part of Olongapo City relative to the main central business district area. The barangay seats at the foot of Kalaklan Ridge while Kalaklan River traverses its boundary in the east. With varying maximum elevations of 366 to 594 meters, Kalaklan Ridge starts from the coastline of Subic Bay in the south ascending to the north side of the barangay.
A little more than half or 57.48% of Mabayuan’s land area can be considered as the built up area of the barangay base on the taxable and non taxable inventory of the City Assessor’s Office. The figure could be higher due to unabated upland occupations and encroachment. Overwhelmingly, utilization of the land is of residential at 99.79%. This can be observed from the upland built houses down to the river side. Institutional Land Use can be found mostly along Otero Avenue including Subic Water Filtration Plant, while Electric Power Sub Station Plant is located in Upper Mercurio Street, Mabayuan. A measly 0.21% of the recorded built up area is commercial area.
With its vast upland territorial jurisdiction, there was not much ecological recorded information of the barangay except for the Kalaklan Ridge’s estimated elevation and land area. At the summit of the ridge is a narrow dirt road was said to be used by loggers then, when forest products was abundant.
Barangay New Cabalan is located in the southwestern part of the City. It is divided into seven (7) Puroks and one (1) Sitio with a land area of 1,995.57 hectares. It is bounded in the North by Sta. Rita River, in the South by Jadjad River along Subic Bay Freeport Zone, in the West by Old Cabalan, and in the Eastern part by Dinalupihan, Bataan. New Cabalan is generally an upland area and is estimated to be at 100 to 200 meters above sea level (http://maps.google.com/maps). It is approximately fifteen (15) minutes away from the City proper.
In addition to the river system within the barangay is the Bangal River traversing in the northern part of the barangay, topographically separating Purok 3, 5 and 6 to Sitio Iram and Pinagpala. In the northern outskirt of the barangay towards the East are two (2) creeks, Gugu and Yutang Creek.
There are currently four (4) land classifications in the barangay. Residential is the largest part which is approximately three fourths (3/4) of the land area. The remaining quarter part of the land is comprised of forest zones, parks, institutional, and commercial zones. Purok 4 houses the City’s sanitary land fill surrounded by a land classified as a forest zone. In Purok 6 is the reserved government lot for future park development. Institutional areas are in Purok 2, 3 and 7. These are the New Cabalan Elementary School, New Cabalan National High School, the Barangay Hall, and the Day Care Centers. Commercial area on the other hand is confined in Purok 2.
Barangay New Ilalim has a total land area of 7.71 hectares. Its general land use is for built-up area and so densely built-up for settlement. According to the Topographic Map as of March 2008, the soils have properties favourable for the rated uses. In the Hydrologic Map of 1982, Barangay New Ilalim do not exclude ground water at greater depth. Its soils are made up of pyroclastic rocks which permeability is low to very low. Basic Soil Map shows that the Barangay, as well as the majority of the City built-up area, is made up of San Manuel Silt Loam and is having a slope of 0-25%, and is subject to occasional flooding.
Sta. Rita River, which has 7 tributaries, and Mabayuan River meet at one point and the river is called Kalaklan River. The waters are taking a long course and passing along 5 bigger densely built-up barangays and one lightly built-up before reaching Barangay New Ilalim. The waters that may have reached the barangay must have already accumulated large amount of silt deposits and nutrients from the watersheds and pollutions from the other barangays. Also, as shown in the photo, the river is being abused by encroachments of residential buildings, which is a violation to the Building Code Chapter I, Section 105 (Site Requirements).
The Kalaklan River is the only biological environment serving the barangay as buffer zone. Therefore, its preservation and rehabilitation should not be taken for granted. It is also reported that during heavy rainfalls and mostly accompanied by high tides, the barangay is easily submerged by flooding because the river cannot already contain the amount of water due to siltation and garbage.
Rivers are wealth of a community. They provide the community of a healthy environment. Non–abusive livelihoods can be generated from it and even tourism. The leaders are challenged for this critical task of providing the next generations a wealthy and healthy environment for their well being. NGOs and grants-providing institutions are very much invited to help.
