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
29 Technical Standards and Guidelines for Planning and Design (DPWH, 2002) was used in rational method. 2.5 THEORETICAL FRAME WORK 2.6 SUMMARY OF RELATED LITERATURE AND STUDIES Flooding is a devastating phenomenon which can cause damage to property. The related literature and studies show that flood should not be taken for granted and should be resolved before becoming severe. Through developing new drainage system there is a possibility that flooding in Desta Homes Subdivision can be prevented.
30 CHAPTER III RESEARCH METHODOLOGY 3.1 INTRODUCTION This chapter briefly discussed the methods of research used, research locale of the study, the, sources of data, instruments for gathering data and procedure for gathering data.
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. Formerly, Desta Homes Subdivision has a total land area of 105,945 sq. meters. But now, the lot was divided into two, namely Villa Desta Subdivision and the Desta Homes Subdivision. The total land area of Desta Homes Subdivision is 67,120.9861 sq. meters.

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
