drainage systems will be supported by the government. 2.4 ASSUMPTIONS Since this project study utilizes the topographic data and actual investigation of the service area, it is assumed that the said data is competent and therefore reliable. The study also utilizes the computer-aided drafting software (AutoCad) in obtaining the total area and area in its sub catchment or region. Also, engineer’s level instruments that is available in the university was utilized in determining the elevation of the service area. The lowest elevation points are assumed flood prone. The rainfall intensity of computed extreme values measured at Makinabang, Baliuag, Bulacan based on 18 years of records by PAGASA is assumed accurate and adapted in this study. A 10-year return period is adapted, and the runoff coefficients from

31 3.2 RESEARCH DESIGN The researchers employed a descriptive method of research. It is a method that goes beyond gathering and tabulation of data. Detailed and factual information was collected. Descriptive method describes the characteristics of a phenomena such as current condition, situation, and practices. It was the most appropriate method in determining the general overview of the Desta Homes Subdivision present situation. Research Locale The study was conducted in Desta Homes Subdivision. It is located in Barangay Atlag in the City of Malolos, Bulacan. It is one of the first subdivisions that was built in Malolos during 1960s.

33 The following was used to gather information and data for the study Interviews The interviews from the residents and community leaders are the primary data that was used. An informal interview was conducted in different parts of the subdivision. In achieving random samples, the researchers used personal judgment in selection of households that are spatially distributed. The researchers utilized the chances and captured distinct and diverse responses. Conducting an interview allowed the researchers to ask residents for maximum level of flood
