The straightened brook flows through densely populated area and partly along cultivated area. The brook is situated in the city of Helsinki. Longinoja brook is an important breeding area for the sea trout of the Vantaanjoki River. The aims of restorations was to create and increase the breeding possibilities for migrating fish and also to improve the area’s landscape. Restoration was part of the project where modern environmental hydraulic engineering methods were studied in the areas with fine-grained soils. The planning aimed to enhance natural conditions and at the same time maintain sufficient drainage level. The restoration project has been a good example of a succeeded co-operation between different organizations and stakeholders. The project was managed by the Finnish Environmental authorities (Finnish Environment Institute and The Centre for Economic Development, Transport and the Environment) and the city of Helsinki. The restoration work was mostly accomplished by volunteers in co-operation with the authorities.
