ANALYSIS OF THE TOPOGRAPHY AND DRAINAGE SYSTEM OF

CHINO ROCES AVENUE, MAKATI CITY TO PROVIDE

SIGNIFICANT AND LONG-TERM SOLUTION

Introduction

Chino Roces Avenue as one of the national and busiest roads in Makati City, serves

many motorists and commuters to different destinations. But few years ago, due to road

repairs and continuous rainfall, water was accumulated on the streets causing floods as

high as 4 feet from the ground. With this problems, significant and long-term solution

must take into consideration because schools, commercial establishments and residential

condominiums are alongside that road.

Background

Chino Roces Avenue, formerly known as Pasong Tamo, is a prominent north-south

road in Makati City. It runs for approximately 5.8 kilometers from Olympia and Tejeros to

Fort Bonifacio. The avenue is named for Joaquin Roces, journalist and founder of The

Manila Times.

South of EDSA via a narrow channel under the Magallanes Interchange, Chino

Roces serves as a frontage road to South Luzon Expressway. It is lined with light

industries and car dealerships on both sides, as well as a few factory outlets. The road

ends at Lawton Avenue within Fort Bonifacio. Chino Roces has a short extension from

J.P. Rizal Avenue into Carmona and Circuit Makati known as A. Reyes Avenue.

Chino Roces Avenue continues to progress economically as commercial

establishments, buildings and other establishments were emerging alongside the road.

This results to huge volume of vehicles passing the road every day. As these

establishments were put into construction, wheelers of trucks, cranes, loaders and other

heavy vehicles passed the road. The road started to get damaged and needed repairs.

Due to substandard repairs, the draining systems of the road were highly damaged

causing floods during typhoons.

Theoretical / Conceptual Framework

To come up with a viable solution to the flooding in Chino Roces Avenue, Makati

City, the researchers are planning to collect data, namely; contour maps, RIDF Curve and

drainage plans of Chino Roces Avenue from the Makati City Engineering Office, PAGASA

and other possible sources. Additional information will be obtained from an interview with

a city engineer knowledgeable about said topic of the area of focus. With all the

informations on hand, the researchers will conduct an analysis and brainstorming to come

up with an efficient and feasible solution to the problem.

Statement of the Problem

Chino Roces Avenue in Makati, City is one of the national roads experiencing floods

during typhoon season or whenever heavy rains are experienced. Vehicles are forced to

take alternative routes since the stretch of Chino Roces Avenue are not passable during

these times. Providing a significant and long-term solution is needed especially along

Chino Roces Avenue lies schools, commercial establishments, residential condominiums

and other businesses and building. Analysing data from the local government unit and

other sources will help the group develop an economical, plausible and efficient solution

to mitigate the problem.

Input- Contour Maps

- RIDF Curve

- Drainage Plans

Process- Interview a city engineer

- Analysis of data

Output- Solution toproblem in theflooded area

Hypothesis

• Are the drainage pipes clogged?

• If the road section flooded has a low elevation, then raising the road level or a

detention tank would mitigate flood problems in the area.

• If the drainage system present in the Chino Roces Avenue is at fault, then

designing a new drainage system will help alleviate the flood problems.

Significance of the Study

The study would give the nearby citizens a solution to the flooding in Chino Roces

Ave. Through the analysis of the drainage system along Chino Roces Avenue and by

knowing the elevation of the said street, the researchers could identify the causes of

flooding and later on would suggest solutions on how to mitigate flooding.

The beneficiaries of this research are the nearby residences, motorists,

commuters, and the public utility vehicles that passes that street regularly.

Scope and Limitations

The researchers would only focus in a particular stretch of Chino Roces Avenue.

Specifically, the researchers will analyse the particular stretch from Magallanes Station of

the Metro Rail Transit (MRT) to A. Arnaiz Avenue. The study would also cover the

breakdown of the drainage system along Chino Roces Avenue and its topography.

Definition of Terms

Contour Maps - a map on which the shape of the land surface is shown by contour lines

Mitigate - to make less severe

RIDF Curves - (Rainfall Intensity-Duration-Frequency Curves) provide information on the

likelihood of heavy rainfall events of various amounts and durations

Topography - an elevation of the ground
