Santa Rosa comprehensive Land Use and Development Plan
PART I - Situationa/ Analysis
THE PHYSlCAL ENVIRONMENT
Flooding occurs along the lakeside of the municipality in Barangays Caingin,
Aplaya and Sinalhan. During periods of flood, solid waste that has not been
properly disposed of, whether on land or in waterways ñnds its way to the lake.
health of the people.
Depletion of Groundwater Resources
Ten of the 18 barangays rely on the Cabuyao-Santa Rosa-Biñan Watervvorks
System sourced from the springs of Matang Tubig in Cabuyao (comprehensive
Town Plan, Santa Rosa, Laguna). The remaining barangays rely on deep wells,
artesian well, open wells and springs. As can be seen, the majority of water
comes from Underground sources. The depletion of such sources is a result of
the increasing demand for water by residential, industrial and commercial
sectors. Aside from the demand, the quality decreases as leachate from
dumpsltes, industries, oil spills and septic tanks infiltrate into aquifers.
Pollution of Laguna Lake
Considering the expected depletion of groundwater resources due to effects of
increasing population, industrialisation and commercialisatlon, Laguna Lake is
seen as a potential source for potable water. At present, the environmental
quality of Laguna Lake is only suitable for fisheries and aquaculture otherwise
categorised as class c (Annual Water Quality Report on the Laguna de bay and
Its Tributary Rivers, Laguna Lake Development Authority, 1996). This is in part
due to land activities resulting in contaminated surface run-off draining into rivers
and streams before flowing into the lake. To diminish the lake's role as a
pollution sink, the LLDA formulated the Laguna de Bay comprehensive Water
Quality Management Plan. Since its implementation, the lake has undergone
considerable improvement. However, the plan's continued success is highly
dependent on the participation of all bordering municipalities.
saltwater lntrusion to the Lake
At the end of the dry season, the level of Laguna Lake is lower than that of
Manila Bay. consequently, a reversal flow from the saltwater bay into the
freshwater lake occurs. However, the presence of the hydraulic control structure
in the Napindan channel prevents seasonal backflow. ln 1996, LLDA undertook
a water quality study that concluded that saltwater lntrusion was not a significant
problem. Therefore, saltwater lntrusion is not perceived as a problem so long as
the flow control channel is operational. On the other hand, the hydraulic control
structure prevents the periodic presence of saltwater to control algal blooms
contributing to the lakes' turbidity.

PART/ - Situational Analysis
Fault Lines Within the Municipality
The southwestern portion of the municipality lies amid the Marikina Valley Fault
system. Future developments should avoid establishment within 5 metres of the
fault line (according to the Philippine Institute of Volcanology and Seismology).
Occurrence of earthquakes and other natural calamities cannot be prevented but
the damage may be minimised if adequate safety precautions are put in place.
Air and noise Pollution
Air and noise pollution is expected to increase as the number of industries
increase and trafñc congestion worsens. Communities situated near the
industrial establishments are prone to the impacts of the air and noise pollution.
Solid Waste Management
Solid waste remains a critical problem to the municipality. At present, one lsuzu
dumptruck services Barangays Aplaya, Balibago, Caingin, Dila, Dita, Ibaba,
Labas, Kanluran, Malusak, Market Area, Pooc, Sinalhan and Tagapo.
There is no dumpsite maintained by the municipality so wastes are thrown in a
dumpsite located in the adjoining municipality of Cabuyao. The remaining
barangays resort to open burning, dumping, burying and disposing into
yvaterv/ ays. Solid waste management can be considered inefficient.
The entire municipality lacks liquid waste treatment facilities. The municipality
resorts to discharging wastes into surface waters, local rivers and creeks.
Consequently, Santa Rosa contributes to the unfavourable class C status of
Geography and Location
Santa Rosa, Laguna is located *within 12196' latitude and 14.19' longitude, 40
kilometres south of Maniia. lt is bounded on the northwest by Biñan. on the south
and southwest by Cabuyao and on the west by the province of cavite. Bordering
the northeast is Laguna de Bay.
The municipality is linked to Metro Manila and other southern provinces by the
South Luzon Expressway (SLEX), the Manila South Road and the Philippine
National Railroad southline, From the SLEX interchange, the municipality oan be
accessed through a national road leading to the adjacent municipality of Silang.
Cavite, Water transport : o the nearby coastal towns is also available.

total land area of the municipality is subject to erosion.
Two types of rocks are found in Santa Rosa: clastic and alluvium rocks,
clastic rocks consist of inter-bedded shale and sandstone with ocoasional thin
Ienses of limestone, as well as tuff and reworked sandy tuffs and partly
tuffaceous shale. These formations are located in the southwestern portion of the
municipality where Sto. Domingo, Don Jose, and portions of Pulong Sta. Cruz
and Malitlit are situated.
Alluvium rocks are found in the remainder of the municipality including the
Poblacion. These rocks consist of an unconsolidated mixture of gravel, sand, silt
Santa Rosa has four series of soil types. ln order of decreasing quantity, these
are: Lipa series, Guadalupe series, carmona series, and Quingus series.
o The Lipa Series
The Lipa soils span deep as it provides moderately well to well drainage
oapabilities. The terrain is characteristically undulating to rolling. Both the
estimated hydraulic conductivity and infiltration rates are moderate. Specific
to the municipality is the Lipa Ioam type of soil, which has the best physical
characteristics among the soil types found in the province of Laguna,
The subsurface soil is characteristically brown to dark-brown in appearance.
Other attributes signify it as a mallow, loose and very friable fine granular
Ioam. lts horizontal boundary is smooth and clear. Subsoil is a dark brown
clay of a friable fine granular tuffessus material with concretions and an
irregular and abrupt boundary. The substratum is highly weathered tuff mixed
with tuffaceous gravels and concretions. lts boundary is broken and abrupt,
o The Guadalupe Series
As a surface layer, the soil is very dark brown to nearly black in colour with an
average depth of 20 centimetres. The undisturbed soil is hard and compact
and bakes easily when dry When cultivated, the soil becomes plastio and
sticky when wet. When dry_ it is coarse, granular and cloddy.
As a subsoil, it is clay, finely granular and sticky when wet. Its coloLr is lighter
that that of the surface soil. The soil is underlain with a zone of voloanio tuff
material with crevices filled with dark coloured soil leached from percolation

2.34 hectares of land along the lakeshore in Sinalhan and Aplaya and in
portions of Tagapc, lbaba, Kanluran_ Malusak. MarketArea and Caingin.
Since Santa Rosa is a generally flat area, it is characterised by none to slight

2.4.1 Temperature and Humidity
Mean annual temperature is 27.50C and is relatively cool due to the site's
elevation and favourable airshed condition. The warmest month is May with an
l average of 30.0“C while the coolest month is . January with an average
i temperature of 25.000
Average relative humidity, the measure of the moisture content of the
atmosphere: is 80% in Santa Rosa. This makes the municipality fairly cooler than
the Metropolitan Manila area where average relative humidity exceeds 81 . O%.
2.4.2 Wind Speed and Direction
Northeasterly winds prevail during the months of October through February.
Winds come from the southeast during March and April. Southerly winds prevail
during May while from June through September southwesterly winds prevail. The
average speed of winds is 5 kilometres per hour.
2.4.3 Rainfall and Rainfall Intensity
Annual average rainfall is notably 1,950 millimetres. The maximum rainfall occurs
in October while minimum rainfall is gauged at 2 millimetres. Though the
municipality is located in a region subject to typhoons, Santa Rosa is hardly
affected dLIe to protection from the outlying mountain areas.
2.5 Air Quality
Neither DEENR nor the LLDA monitor air quality in the municipality. However, an
investigation was conducted in 1994 for EIS purposes. Although dated, the study
concluded air quality to be well within allowable limits.
2.6 Waste Management
i 25.1 Solid Wasütes
i Solid waste remains a problem for the municipality. Figures project solid waste
generation to 42,474 kilograms/ day by the year 2000. The generation will surely
increase two-told with anticipated industrial development. The problem is most
critical in the Poblacion area and market places. At present, one dumptruck
services 13 barangays (Aplaya, Balibago, Caingin, Dila, Dita, lbaba, Labas,
Kanluran, Malusak, Market Area, Pooc, Sinalhan and Tagapo). The waste
i? materials gathered by these trucks are transported to the municipality of
_ , n Cabuyao where the nearest dumpsite is located. This site is located in a low and
' i eroded lot. The remaining barangays resort to open burning, dumping, bunying
and disposing into waterways, Solid waste management can be considered
inadequate and inefficient. Ailowing the municipaiity's solid waste management
practices to continue promotes major problems like vector diseases, polluted
waterways. ccntaminated aquifers anc increased flooding. There exists an
cbvious need for a sanitan/ landtil: site away from any waterbcoies to improve

PART/ - Situational Analysis*
3.0 POPULARTlON AND SETTLElVlENTS
The rapid urbanisation of Santa Rosa has brought forth a number of Concerns
that have significant implications on the future cširection of the municipality,
§kewed Populatpg and Density
Santa ltosa is divided by the South LLrzon lšxpressway/ (SLEX) into two major
sections: northeast and southwest. The northeast section oomprises 58% of the
municipalityb total land area, uihile the southwest consists of the remaining 42%.
Settlements are concentrated in the northeast portion with 91% of the total
population residing in the area for a density of 39 lpC-JFSOTTS per hectare. This
skewed settlement pattern creates congestion especially towards the centre of
the municipality and on the lakeshore areas.
As in most urban areas, squatting is also prevalent in Szanta Rosa. Most squatter
colonies are located in environmenšnlly critical zones such as the lakeshore area
(Barangays Sinalhan, Caingin and Aplaya) and along rivers, creeks and irrigation
canals. High-risk areas such as those along the railway and adjacent to
industric-: s are also inhabited by squatters.
S_c. atte__red_d_e: v_el_orz@
The direction of growth of Santa Rosa cannot be clearly defined on spatial terms
as most existing and new developments indicate a very scattered and sporadic
pattern. Compr-. ict development areas are llrhitid to the southwest portion where
large landhrzvlclings are located. This implies that dr-: veloprnent etiorts are very
dependent on individual and Lin-rtzlzrted deoisrorrs, hence preventing a cohesive
and organised structure.
One of the development goals that are indicated in *lite 1990 Comprehensive
Town Plan is maximum utilisation of land resources. Hovueiser", almost 20%; of the
municipalitys land area are left iclle, a considerable portion of which are classitiecl
as rurime agricultural lands.
3.2 Population: Levels, Growth, Distribution and Movements
3.2.1 Levels and Growth Pattern
The municipality of Santa Rosa registered a total population of 138,257 'in 1995.
From 41,335 in 1970, it increased by more than three times over' a 25-year
period. While the population level exhibited consistent growth over the years, the
rate of growth was highest during theiperiods 1975-1980 and 1990-1995. There
was a. significant tapering off during the period 1980-1990. Assuming the
persistence of the geometric rate or' growth of 7,394; registered between 1990 and
li' 1995, the '1998 mid-year population of the rnurwrcipalityr was ezaiimated to reach

The growth pattern of Santa Roses population from 1970-1975 and 1980-1990
has been oonsistent with that of the province. Thus, it may be construed that the
unprocedented increase in population growth experienced by the municipality
during the two periods (1975-1980 and 1990-1995) was ispurred hy events that
transpired within the local boundaries and not a natural taocurrence across the

3.2.2 Population Age-Sex Structure
The age and sex oomposition of Santa Roses population in 1995 is shown in
'Table 3,3. There were slightly more females than males, thus the over-all sex
ratio approaches 98, ie. , there were 98 males for every 100 femaies in the
municipality. The sex ratio, howáver, »vas highest in the extreme lower and upper
age groups, iegistering much as 107 malrgs per 100 femates. Consequentiy,
the females outnumherect the males within the bracket oorresponding to the more
productive years of vrorkirg life Stuart, at agies 15 to 34 years. This does not
itte-ari, Iiowevtar, that tiltšfe is; climiriisiiiriç; procluctivity beyond age 34, but rather it
shows that the population structure is very much influenoect by the presence of
jobs in the locality, the nature of Which often reouire younger and temate workers.
The reoent population structure clearly manitests the "setective tri-migration"
taking place in Santa Rosa spurred by its continuously growing economic
activities. The dominance of males over femates in terms of number began to
pick up only after age 35 up to age 49. after which, it tapered off dipping as low
62 at the extreme upper age bracket. The relatively low ratio again
strsengthens the conjecture of longer life expeotancy among the females.
While it defines the volume of demand for various goods and services and supply
of human resources. the age-sex structure of a poputation distribution presents
important implications to future population grovirth, both in terms of im nediate and
long-term taffocts. For instance, the fact that 57% of the female population of
Santa Rosa in 1995 were in their reproductive ages (15-49 years) may indicatre a
rising birth rate at least in the near future.

Data on population distribution and population clensities by barangay presented
in the following tables indicate the unbalanced and skewed spatial distribution of
the town's population (refer to Figure 3.1), The 1995 population data indicates
that the most populated barangays of Santa Rosa were Dila, Sinalhan, Dita, i?
Tagapo and Pooc, accountiiwg for around 45% of the municipalitys aggregate
Expectedly, the most densely populated areas were those located nearest lo the
centre. Barangay Kanluran exhibited the highest population concentration of 237
inhabitants per hectare. Barangays located within the vicinily of the market area
posted population densities ranging from 138 to 170 persons per hectare. These
barangays include Aplaya, Malusak and Market Area. Given their vast land area
coverage and distance from the town centre, those barangays with the least l, W
population concentration included Don Jose, Malitlit and Santo Domingo with, 'g
densities ranging from only 1 to 6 persons per hectare. Refer to Table 3.7.

Because of the scarcity or even lack of data on migration or population
movements, interences were made using the growth pattern of each barangay of
the municipality between 1990 and 1995. The table below clearly shows that two
of the barangays (Malusaik and Kanluran) were outumigralion areas between
1990 and 1995, losing as much as 6% of their population to other barangays
most probably within the municipality. Remarkable increases were noted among
Barangays Dila, Malitlit and Pulong Santa Cruz, which grew by 26696, 120% and
84%. respectively, in a relatively short period of 5 years (refer to Figure 3.2).
Such unprecedented growth may not be possibly attributed solely to natural
increases but rather to in-migçration at a large extent Refer to Table 3 8.
