Description of Study Area

The study area, having an area of 48.8 acres, is primarily an undeveloped parcel of land that has coarse loamy soil and depressions located in vegetative areas. All the streets in general follow the natural slope, and the adjacent areas to Queen and Lopez Streets are located at lower elevations comparatively. However, the residential lots are graded toward the street at a slope of 2% so they can drain easily. The study site drains through a subsurface pipe network at the confluence of Queen Street and Edwards Street to the north of the site. This confluence node denoted as O1, is the pour point or outfall of the study catchment area. Figure 2.1 shows a schematic of the drainage area and conveyance network with their contributory subcatchments. The network object summary has been listed in Table 2.2.
