GEO-PHYSICAL ENVIRONMENT

Geographic Location

Tanauan City is located within 121°6’ latitude and 14°5’ longitude at the North-Eastern part of Batangas.  It is bounded by Talisay, Batangas in the West, Malvar and Balete in the South, Sto. Tomas in the East and Calamba, Laguna in the North.

Because Tanauan City is strategically located near major growth centers like Metro Manila and Batangas City, the city is prone to urbanization. The City is also strategically located between two important natural resources, Taal Lake and Mount Makiling.

 

TOTAL LAND AREA OF BARANGAYS

Topography

The City of Tanauan covers a total land area of 10,716 hectares which represents 3.38% of the total land area of the province (316,581 ha). Majority of the areas in Tanauan City belong to 0 to 15 percent slope that are undulating to rolling. Most of the areas with steep slope of more that 65 percent are located in Barangays Sulpoc, Montana, San Jose, Maugat, Ambulong, Bañadero, Talaga, Banjo West, potions of Darasa and Poblacion 3 (refer to Figure 3.2).

Steep hills and mountains with slope of 30 to 65 percent are located in Suplang, Suploc, Balele, Wawa, Boot and Maria Paz. Barangays which belong to 0 to 3 percent slope are portions of Laurel, Malaking Pulo, Altura Matanda, Altura Bata, Altura South, Montana, Luyos, Cale, Bilog-bilog, Pantay Bata, Pantay Matanda, Sala, Pagaspas, Trapiche, Poblacion Area, Natatas, Bagumbayan, Hidalgo, Sambat and Darasa. The slope in these barangays is gently sloping to undulating. The rest of the barangays have 8 to 15 percent slope that are undulating to rolling. Mt. Makiling, with a spot elevation of 1090 m, is approximately within four (4) to five (5) kilometers from the city (refer to Figure 3.3).

 

Geology

As Tanauan is situated between two volcanoes, Mt. Makiling and Taal Volcano, its geologic structure makes it prone to volcanic activities. The City is mostly composed of Pliocene to Quartenary volcanic rocks of agglomorate, tuffs, cinders, andeside, dacite and pyroclastic layers. Thus, the City geographical composition mostly came from igneous materials (refer to Figure 3.1).

Quartenary volcanic or Pliocene recent igneous rocks are composed of active and non-active cones and lava flows consists mainly of dark gray to black andeside, basalt and aphanemitic.

Pyroclastic materials on the other hand, are ejecta consisting of unconsolidated materials of different sizes that are explosively or aerially deposited from volcanic vents. Volcanic tuff was formed mainly due to ashfall and continued lava flow.

 

Land Resources

Soil Type

There are four soil types that can be found in Tanauan City. Majority of the soil are Taal fine sandy Loam followed by Lipa Loam (deep phase), Lipa Loam and Tagaytay Sandy Loam (refer to Figure 3.4).

 

The four soil types of the city are provided below.

Lipa Loam

This comprises about 1,354.1 hectares or 12% of the total land area of the city. This type of soil can be found in the southeastern side of the city. All of the urban barangays have this type of soil and portions of rural barangays namely Banjo West, Banjo East, Hidalgo, Mabini, Tinurik, Bagumbayan.

Lipa loam, like the Ibaan loam, is a residual soil representing the decomposition products of the underlying volcanic tuff material. It is dark brown, very friable, mellow and easy to cultivate. Its depth ranges from 25 to 35 centimeters. The subsoil is dark, loamy in texture, and becomes heavy and waxy at a depth of 75 centimeters or more. In some areas, there are gravels and concretions are exposed in highly eroded sloppy and hilly portions. According to Dorsey, this type of soil evidence is of lasting fertility. In fact, it has the best physical characteristics that can be found in any soil. However, the present system of agriculture has led to the depletion of the soil because of the pronounced effect of erosion. This type of soil is well developed in Lipa, Malvar and Tanauan.

Lipa Loam (deep phase)

This type of soil covers about 2,541.4 ha or 23% of the total land area of the city. It is usually found in the eastern portion of the city, along the San Juan River and some adjacent barangays.

Lipa loam deep phase consists of 25 to 35 centimeters of surface soil and 57 to 100 centimeters of subsoil. The parent material is about 120 to 150 centimeters from the surface. These areas are located on the lowland of Santo Tomas and East of Lipa, near Halaraya Mountain

 

Taal Fine Sandy Loam

Most of the barangays have this type soil. It comprises almost 6,216.00 ha or 56% of the total land area of Tanauan.

Taal fine sandy loam consists of light-gray loose and structureless fine sandy loam surface soil. When wet, the color is dark brown to black. The depth ranges from 0 to 40 centimeters. Below this surface, soils are several thin layers of volcanic sand separated by thick horizons of fine sand. In general, the surface and subsoil are loose and seldom compact.

Taal fine sandy loam is the biggest type of the Taal series. This comprises the rolling lands, hills and mountains east, north and west of Taal, covering portions of the towns of Lipa, Tanauan, Taal and Calaca.

This soil produces good crop of sugar cane every year. Because of its physical properties, it is easily prepared. Sugar cane is extensively planted in Calaca, Taal and Talisay. Corn, rice, vegetables and citrus trees are also grown. Cacao and coffee are planted in patches along shaded areas, especially in the backyards. Upland rice and coconut are also planted in this type of soil in Talisay and Tanauan.

Tagaytay Sandy Loam

This soil type covers only 951.2 ha or 9% of the total land area of the city. They are found in barangays northwest of the city, namely Suplang, Suploc, Montaña portion of Longos, Altura Bata and Malaking Pulo.

The 12 to 50 centimeters of surface soil of the Tagaytay sandy loam is dark-brown to nearly black friable and granular sandy loam soil with considerable amount of volcanic sand. The subsoil is dark brown to very dark brown, and varies in texture from clay loam to clay. This is sub-clay or volcanic tuff. The tuffaceous material varies in depth according to the topography of the place.

In some places, especially near the ridge, there is a zone of volcanic ash accumulation just below the surface soil. This zone, however, disappears in well-cultivated or highly eroded areas.

Climate

Tanauan City falls under the first type of climate with two distinct seasons: dry from December to April and wet for the rest of the year.  Its climate can be described as generally mild.  Because of its proximity to Mt. Makiling, Tanauan is shielded from the North East monsoon and part of the trade winds but is prone to the South East monsoon (refer to Figure 3.8).

 

Freshwater Resources

Natural Hazards/ Constraints

Erosion Potential

Barangays located near or along Taal Lake with slopes 8 percent and above are slightly to highly susceptible to erosion (refer to Figure 3.9). The rest with slopes of 0-8 percent are not susceptible to erosion.
