The Impact of Recurrent Flooding on Residential Property Values and Purchaser Risk Awareness: A Case Study of Shah Alam, Selangor, Malaysia

Abstract

This study investigates the impact of flooding on property values and the level of flood-risk awareness among prospective homebuyers in Shah Alam, Selangor. As a rapidly developing urban centre, Shah Alam faces frequent seasonal flooding, which poses a significant challenge to the local real estate market by influencing both asset valuation and residential preferences. Despite ongoing mitigation efforts, the complex relationship between flood incidents, property depreciation, and buyer behaviour remains under-explored. The primary objectives of this research are to analyse the effects of flooding on housing values and to evaluate the awareness of homebuyers regarding flood-prone areas. Adopting a mixed-methods approach, the study utilizes a survey of 70 homebuyers in Shah Alam alongside house buyer preferences and awareness. Findings reveal a high level of risk consciousness: 71.4% of respondents consulted flood-risk maps prior to purchase, and 70% were aware of the flood history of their target areas. Furthermore, 48.6% indicated they would seek expert consultation before committing to a property in a high-risk zone. These results suggest that homebuyers are increasingly proactive in mitigating environmental risks, a trend that carries significant implications for future housing market dynamics and urban policy development.
