This could explain for the lack of buildings in the South region of Gombak because of the steepness of the slopes evident by the closeness of the contour lines, which could result in higher developmental costs for the construction of any buildings in that area. However, with the low-elevated land areas of Gombak already having features like waterbodies and housing areas which we would want to avoid, we might have to consider the selection of the suitable site being in the South area of Gombak.

OVERVIEW PROXIMITY CRITERION SCORES AHP SUITABILITY
Gombak Study Area with Proximity Map of:
- Roads (Top Left)
- Buildings (Top Right)
- Natural Features (Bottom Left)
- Slope (Bottom Right)

Apart from the Slope Layer (Bottom Right), the proximity views for roads, buildings and natural features were digitized showing the proximity range from 0 metres to 200 metres. This provides us uniformity across these views as well as clearer insights of how these features might affect the site selection for the CDQC in Gombak.


ROADS
From the Proximity Map for Roads View (Top Left), the proximity of the roads seem to span across majority of the Gombak area, indicating that most of the areas in Gombak are accessible within 200 metres of its service roads and tracks. However, there are areas digitized in black, indicating that these roads are not accessible within 200 metres of these roads, in which these areas are less likely to be considered for the suitable site for the building of the CDQC in terms of Accessibility.


BUILDINGS
From the Proximity Map for Buildings View (Top Right), the proximity of the buildings seem to span across the North and Central region of the Gombak area, indicating that most of the population in Gombak are situated in these regions. Therefore, we would consider the areas digitized in black for this map view, where these areas are at least 200 metres away from such buildings, thus these areas being more likely considered for the suitable suite for building the CQDC in terms of Health Risk.
