The roads in the areas surrounding the low-lying areas surrounding Jimbaran, south of Bali's main airport, are increasingly susceptible to flooding, even in periods of only medium rainfall.
According to BeritaBali.com, the tendency towards flooding in Jimbaran is due to the uncontrolled development along the Jalan By Pass leading to Nusa Dua, built with little regard for existing zoning rules and the impact of their projects on the environment. The problem of over-construction, without adequate allocation of open-space for water absorption, is compounded by the prevalence of lime stone in Jimbaran's soil composition. Limestone laden soils tend to hold rain water, rather than provide an effective medium for absorption.
Overwhelmed when frequent flooding occurs, police officials working in the area can do little more than direct passing vehicles to form a single file and keep to the high side of the road as they navigate bumper-high flood waters.
The increasing severity of flooding along the Jimbaran By Pass is complicating traffic flows, isolating the many thousands of tourists and tourism workers who must pass this road every day.
The secretary of Commission B of the Badung Regional House of Representatives, Wayan Sudiana, confirms the frequent flooding occurring regularly in his home district of Jimbaran. In Sudiana's view, much of the flooding can be sourced to drains and ditches that do not operate in an optimal manner. The use of drains for garbage disposal and silt deposits which have reduced the depth of drainage ditches all contribute to flooding.
The main culprit, however, for Jimbaran's flooding is seen as tourism-related construction. Warned Sudiana: "Permits must be properly controlled; permits must not be issued solely for issuing sake. And the appropriate government agencies must be prepared to take action (against violators)."
