This study illustrates how the hedonic pricing method can measure the value of environmental assets in an urban setting. A HPM valuation, utilising relatively easily accessible secondary data, and a semi-logarithmic regression form, is used. The value achieved was substantially greater than either expenditures to date or the actuarial valuation of Lake Illawarra. The study demonstrates the applicability of the technique and recommends its further development and use for this type of public decision-making. A range of other data was also generated that adds to the usefulness of this approach for general planning purposes.
