Water facility shortage Figure 5.24 shows that the site lacks proper water facilities—only a few pumping stations downstream. The pumping station intent to drain water from the community to the stream, but it does not work during flooding because the stream stage always is higher than the community, caused by the water drained upstream. Moreover, there is too much outside run-off flow directly from upstream that is always beyond the facilities’ limit. Figure 5.24 Waterways - Water Facility - Easily Flooding Area
Risks of Soil Liquefaction Figure 5.25 shows high risks of soil liquefaction in the site, especially around the central communities and the potential developing areas. It caused by soil quality, sandy soil. Soil liquefaction is one of the significant issues that the risks increase after the flood, or we set some functions to work as the detention basin.
