General planning
A master plan is a general plan that guides the planning of a municipality's urban structure and land use. It outlines the use of areas in the municipality. The overall expected validity period of a master plan is approximately 15–20 years. However, several changes to the plan's sub-areas, i.e. partial master plans, can be made within this period. In areas for which local plans are intended to be drawn up, a legally binding master plan guides local planning. In areas that are not subject to local planning, the master plan directly guides construction and land use.
The current master plan for the city of Hamina can be found in its entirety on the joint map service of the neighboring municipalities in South Kymenlaakso. (You can view more map layers in the Materials menu on the left side of the map service)
