For exploring and discovering the main knowledge, experience and practices, four main issues were analyzed: what were the goals of the involved participants regarding the community involvement in the spatial and community planning; what methods were used to extend the involvement of community members; what problems and obstacles did the project participants face, and what were the main lessons learned. This study provides reflections (analysis, comparison and evaluation) on community involvement in participatory process in coastal areas of the Baltic Sea Region by investigating the methods, which were used in community involvement in project participating countries; and its influence in improving local governance of the local territory development.
