Group 3: Future Plans and Community Response - To fundamentally resolve the waterlogging issue, it is necessary to reconfigure the drainage pipes within each ground-floor unit, which requires consent from the residents [3]. - The local street office reported that 19 out of 20 ground-floor residents have agreed to the necessary construction, and efforts will continue to communicate with residents to expedite the work, aiming for completion before the upcoming flood season [3].
