AbstractParks and open spaces enhance the quality of life in urban areas. Over the last 15 years, the city of Boston has sponsored the most expensive urban infrastructure project in history. This project relocates an elevated highway underground and creates urban parks, increasing the city's green space. The study estimates the economic benefits of proximity to parks in Boston, Massachusetts, based on hedonic pricing methods. Using Boston's land use and assessed property price data, it is determined that proximity to urban open space has positive impacts on property values, while proximity to highways has negative impacts on property prices. Based on this observation, it is expected that the spatial alteration will cause a significant increase in nearby property prices.
