Valuing amenity: public perceptions of sustainable drainage systems ponds

Understanding the potential concerns and needs of residents is key to achieving good acceptability of sustainable drainage systems (SuDS). This paper highlights, through the application of a structured questionnaire, the potential value to residents of living in close proximity to a SuDS pond. The results show that although the pond's characteristics are not the main factor influencing the choice to move into an area, its effect is markedly positive. Contingent valuation of the benefits is used to show that the additional value brought by SuDS amenity, when monetised, can offset a pond's initial construction costs and ongoing maintenance, hence ensuring the return on investment for developers. By building on existing research, this paper highlights major changes in the perception and valuation of pond structures.
