The balance between urban development and forest and green spaces conservation is of paramount importance. Such balance can be present and argued to private developers based on a costs and benefits analysis of preserving forest areas and green spaces in urban spaces. This raises the question of what is the economic value for such amenities. To explore the value of urban amenities, the project proposes an approach based on individual spatial data, i.e. residential transactions. Buildings and transactions are located with a high degree of accuracy, which will be useful in identifying similar/comparable properties and areas for statistical analysis. In particular, this approach will make it possible to identify transactions carried out around "treatment" zones (i.e. close to protected woodland areas) and "control" zones (i.e. at a greater distance from woodland areas) depending on the characteristics of the built environment, but also of individual properties. The methodological approach is to divide the transactions into two distinct groups: i) a first group located in close proximity to the protected woodlands (direct access from the backyard or front yard); and ii) a second group located in close proximity to the protected woodlands but without direct access (one to two blocks away). Cross-comparison of price differences will establish a value effect that varies with the degree of exposure.
