7. โข Construction of Public Infrastructure is often:
โข Time-Consuming โ often takes years to accomplish
โข Capital Intensive โ costs money and labor
โข Intended for long-term or permanent use
โข Planning for Public Infrastructure should always:
โข Absolutely Necessary โ if viable alternatives exist, then
building structures should only be the last resort
โข Minimally Invasive โ it should not disrupt biodiversity and
ecological balance, especially in critical habitats
โข Cost-effective โ the benefits should greatly outweigh the
drawbacks (maximum gains for minimum cost)
โข Involve consultations with concerned sectors to ensure
that their welfare will be given the utmost priority
โข Conform to pre-existing laws

Laguna de Bay is fed by waters
from 21 tributaries:
And has only ONE outlet to the
sea: Pasig River.
11. Mt. Gonzales
โSungayโ
(2326 ft.)
Mt. Makiling
(3580 ft.)
Mt. Banahaw
(7120 ft.)
Mt. San Cristobal

Areas shaded ORANGE
denote largely deforested
areas of the Laguna de
Bay watershed.
12. Maximum Depth: 20 m
Average Depth: 2.7 m
The deepest
parts of the Lake
(Deep Blue) are slowly
filled up with silt and
sediment, drastically
decreasing itโs carrying
capacity
RED denotes the mean water level while
GREEN indicates a critical overflow level
The western
shoreline of the
lake is the area most
susceptible to flooding,
as it is lower than the eastern
shoreline (bounded by the Sierra
Madre Mountain Range)
NAPINDAN CHANNEL is the only
outlet of the Laguna de Bay to
the Sea.
13. Shaded in Red are parts of the
Laguna de Bay watershed which
were submerged in water during
Typhoon Ondoy (Ketsana)
Notice that Metro
Manila received the
worst flood. Other
than being the most
densely populated,
it is the only part
which is lower than
the mean water
level of Laguna de
Bay during storms.
14. โข Reopen the Napindan Hydraulic Control Structure in Taguig
to allow the natural ebb and flow of brackish estuarine water
from Manila Bay to the lake through the Pasig River
โข Utilize the Tapayan, Labasan & Taguig pumping stations to
control the volume of discharged water from the Lake
โข Conduct regular periodic dredging of the lake bed to remove
accumulated silt and sediment, increasing the lakeโs carrying
capacity
โข Rehabilitate the Laguna de Bay watershed through discipline
and proper conservation procedures (reforestation, proper
waste disposal, wastewater treatment, removal of large fish
pens, population control of invasive species)
WHAT IS THE BEST SOLUTION?
15. In reality, the Laguna Lake
Expressway Dike PPP does not
solve anything at all. Rather, it
further aggravates the problem it
aims to solve, while it creates more
and more problems in the process.
And it costs PhP 124.91 billion.

P57.89B + Right-of-Way- P2.1B)

PAPAANO KUNG LUMINDOL?
PAPAANO KUNG BUMIGAY ANG DIKE
SA DAMI NG NAIIPONG TUBIG?
17. TUTULAN ANG LAGUNA
LAKESHORE EXPRESSWAY DIKE!
โขBilang isang Public-Private Partnership,
Hindi ito pabor sa mamamayan
โขTinantanggalan nito ng kabuhayan ang
mga mangingisda at mag-iitik
โขSinisira nito ang kalikasan ng Lawa
โขMaaring magdulot ito ng malaking sakuna
