Land-use planning

Planners need geological information to solve problems within municipal planning processes based on specified planning level and regulations, which ultimately has its legitimacy in the Planning and Building Act (PBA). This constitutes an significant context for how geological information and expertise can help in the planning of land use in a municipality.

This approach has had an impact on how the structure and functionality of the Map Browser "Geology in my Municipality" is designed.

It is the Planning and Building Act that defines municipal planning and therefore also forms what is needed by geological information. In the first phase, the plan strategy adds constraints, where the purpose is to focus on planning functions the municipality should start up or continue, facilitating a constructive development. The municipal planning strategy is not a type of plan, but a tool for the municipality to determine the further planning work. Work shall include the municipality 's strategic choices related to the development of society. Already through the choices made in the municipal planning strategy, the planner starts to refine the planning needs related to geological information.
Planning programs should be created by plan startup for all regional plans and municipal plans (including the social elements) as well as for zoning plans with "significant effect on the environment and society". This affects the purpose of planning, alternatives to be studied and the need for decision-relevant topics such as geology (resources , risk , etc.).
Municipal plan and zoning are then executed. The Municipal Master Plan shall consist of one social element, including a Programme of action and Land-use part. The action component shall be updated annually. The Planning and Building Act operates with zones requiring special consideration for land-use purposes, describing restrictions that affect the use of land. It is therefore important to show what geological elements may be included in this type of discussion. These can be linked to regulations and guidelines to plan documents.
Both municipal and zoning may require risk and vulnerability assessment (ROS) and environmental impact assessment (EIA). Work with municipal plans and zoning generates a variety of geological information needs. ROS for example, requires knowledge of risk factors. Delineation of hazard zones require similar types of information. For location of housing estates (land category buildings and construction by the Building Code), may for example involve risk factors associated with the geology must be demarcated. For other situations and needs, municipal planning might derive other types investigation needs. For example, in EIA context it might be important to ensure that natural resources are not added ribbon through housing, or values ​​related to soils, minerals or groundwater is known in relation to the preparation of business plans. This means that the geological themes not necessarily reflect land-use classes in the Planning and Building Act directly, but is derived from the information requirements in the planning process performed.
