Landscape assessment is a sub-category of environmental impact assessment (EIA) concerned with quality assessment of the landscape. Landscape quality is assessed either as part of a strategic planning process or in connection with a specific development which will affect the landscape. These methods are sub-divided into area-based assessments or proposal-driven assessments, respectively. The term 'landscape assessment' can be used to mean either visual assessment or character assessment. Since landscape assessments are intended to help with the conservation and enhancement of environmental goods, it is usually necessary to have a fully geographical landscape assessment as a stage in the process of EIA and landscape planning. During the initial phases of a project, such as site selection and design concept, the landscape architect begins to identify areas of opportunity or setbacks that may provide constraints. The architect prepares alternative options in order to compare their assessments and identifies the proposals which allow for the least adverse effects on the landscape or views. A landscape professional works with a design team to review potential effects as the team develops a sustainable proposal. Upon developing a design proposal, the landscape professional will identify and describe the landscape and visual effects that may occur and suggest mitigation measures to be taken in order to reduce negative effects and maximize benefits, if any.
