4.19.02 Case Study: A Barangay Map Survey and Information Product

Mon, 11/26/2007 - 20:12
The Case Study Area
Linao is a Barangay located in the west end of Ormoc City Urban Area. The Barangay became urbanized after the flooding in Ormoc in 1991 when a number of relocation sites were located in the Barangay. Prior to that, the area was mostly agricultural and industrial lands.

Linao has a number of issues and inconsistencies when it comes to actual land use compared to the zoning of the Barangay. When comparing the aerial photo with the zoning, there are two major industrial activities (Petron Depot and the Mac Builder Corporation) located in an area which is zoned as residential. There is also a widespread area of informal settlements along the coastal areas which are not presented in the CLUP.

Barangay Linao has a total land area of about 87 hectares of which 50% is used as agricultural land and 30% as residential. The rest is used for industrial, commercial and institutional activities. There is a large swamp in the western part of the barangay. The Barangay used to be zoned as Industrial and has a large Petrol depot located in the central area. Later on, the zoning was changed to residential for the most part of the Barangay, except for the area where the schools and the Barangay hall are located, which is zoned as institutional.

Today the population of Linao is around 9,000. Since 2003, there was a 32% increase in this number. Linao has one of the extensive areas of informal settlements in Ormoc City where just along the shoreline alone, there are approximately 200 households. The other 50 households are located in other parts of the Barangay.

There is a problem with lack of nutrition for the children living in the informal settlements, and apparently, this is due to the lack of adequate land to grow vegetables along the shore. Barangay Captain Sofronio Chu has started a program to grow plants in bags and plastic boxes which they distribute among the settlers to improve their ability to grow plants.

In the Barangay hall today, they have no map that covers the whole area. The only map available is a Tax Map showing the Tax Parcels in central blocks. The map lacks topographical references and even the Barangay Captain and his staff have a hard time locating the precise points that the map presents.

Scope

The main target of this survey is to gather useful data in the preparation of the CLUP and at the same time gather information for the preparation of a Barangay map to for use in the barangay hall.

The scope of this survey is to:

  1. Compare the Zoning with the Actual Land Use;
  2. Identify major changes in land use, newly built-up areas etc;
  3. Identify issues obtaining in the Barangay;
  4. Prepare findings for use in updating the CLUP, including a Land Use map;
  5. Locate facilities in the Barangay.

Preparation

In preparation for the barangay survey, a meeting was held with the Barangay Captain, and secondary source materials such as aerial photos were used in locating the different objects of land uses that should be included in the survey. These were also marked on a map.

Prior to the survey the following activities were conducted:

  1. Scheduled a meeting with the Barangay Captain;
  2. Put together a survey team with a driver, a GPS operator and a person to take notes and pictures during the survey;
  3. Prepared note-taking forms for the survey (GPS point ID, photo number, name of location or activity etc);
  4. Prepared Maps to note the different objects to include in the survey;
  5. Made a list of objects and questions for the Barangay officials that are of interest to the survey;
  6. Made sure that the following were available: vehicle, GPS recorder, digital camera, extra batteries etc.;
  7. Prepared for outdoor walking,
  8. Prepared survey team provisions such as drinking water and raincoats.

It is good to have a survey team member living in the area who. Thus, the team is familiar with the different locations and can provide additional information during the survey.

Implementation

The survey started with a meeting with the Barangay Captain who went through a list of different services located in the Barangay and noted them on the aerial photo.

With the help of the Barangay Captain, the locations of sports facilities such as badminton hall, basketball courts and a sports hall under construction were plotted on the map, including schools (an elementary and a high school), a health center, police station, churches, bakeries, industrial activities, etc. that have been constructed and where new residential areas have appeared since the aerial photo was taken in 1997. He also presented other information about the barangay.

Also identified on the map was the swamp area that is not suitable for residential use but is within the residential zone.

The Barangay Captain also joined the field survey around the vicinity of the Barangay Hall, which took less than one day and covered interesting sites that are useful in the preparation of the full barangay survey. Some basic attribute data were also elicited from the elementary school principal and the Barangay Police Chief in Linao.

After the interview, the survey team drove around the Barangay visiting the different sites to gather GPS readings and take pictures of the objects, and at the same time looked out for other interesting objects in the area to survey that may relevant for the CLUP preparation and for the Barangay Map.

Objects Surveyed

The different objects listed by the Barangay Captain were visited during the survey. The team also ‘discovered’ and surveyed a residential area that is actually a housing area for urban poor which has been built after 1998 when the aerial photo was taken. This was noted among the objects to be surveyed. In total, 28 objects in the barangay were surveyed, ranging from industrial activities to bakeries and sports facilities. The Barangay Police Chief also provided information about crime rate in the area, and the elementary school principal gave data about the school.

Processing data and updating the Land Use Map
During the conduct of the survey, it was determined that the Zoning in Barangay Linao was not reflective of the actual or even intended land use in all areas of the Barangay. This is illustrated by the Petron Plant which is a highly hazardous industrial activity. It is a permanent structure that is located right in the middle of a residential area. The Mac Builder area is also located in the residential zone.

With this data and with the use of aerial photo, the current land use map can now be updated to have a better input for the next CLUP preparation process.

Based on the survey, the residential area was subdivided into smaller parts and the data for the major land areas were changed from residential to agricultural use. The areas occupied by Petron and Mac Builder were changed to industrial use, and the swamp area in the west end of the barangay was also indicated. The updated Land Use Map forms a good base for the updating of the CLUP and for a more accurate zoning for the barangay.

Preparing the Barangay Map

With the use of data gathered during the Barangay Survey it is also possible to prepare a barangay map that shows the location of facilities available in the barangay such as the Barangay Hall, Police Station, Health Center, Schools, Religious facilities and sports facilities.

The barangay map is a useful information material in the barangay, and serves as an important tool in the political process when discussing development and visualizing the need for new locations for ongoing and proposed activities at the barangay level.

The barangay map for Linao is printed in an A2 format, and laminated so it can be used in discussions where the local officials can also draw on the map with whiteboard markers and reuse the map for different projects.
