When disruptive developments such as sewage plants and phone towers are constructed in a neighbourhood, one result can be a fall in property prices. In the West, there are planning committees and environmental groups that push for mitigation on developments but most Asian countries do not have these. Instead, residents will petition local governments about the dis- ruption of the fung shui and demand that the project be stopped or modified or that compensation is offered by the developer. While construction will undeniably affect an area's energy, it is important that fung shui opinions are sought from several reputable masters. A reliable way of assessing a practitioner's quality is through his or her track record with clients. Publicity or an output of books are not necessarily trustworthy indicators. Neither is membership of any statutory fung shui board or association. Indeed, reputation is an intangible quality that is difficult to quantify. Some projects may have been cancelled as a direct result of fung shui concerns, such as underground tunnels boring through mountains. But how does one justify and quantify financial compensation in fung shui terms? We will consider this next week.
