Clarion/Samuels has studied development impacts on residential and commercial property value. Aside from typical development proposals (residential subdivision, commercial and industrial development) Clarion/Samuels has done studies of the impact of cellular phone towers, contaminated property, wind farms, wastewater treatment facilities, natural gas pipeline compressor and dehydration stations, and other externalities on residential and commercial property value.
While each study is unique, a typical pattern of analysis includes:
A review of potential impact generation, noise, light, vibration, view, automobile, truck and train traffic, etc.;
An analysis of the the environment within which the potential source of the impact is to be located. The relationship between the source and the properties that may be impacted is critical;
A review of national impact literature;
Case studies that replicate both or either of the potential source of the impact and the potentially impacted properties put the types and extent of the potential impact into context; and
Where possible, hedonic and other methods are utilized to confirm, deny or enhance the application of the literature review and case studies.
