From the dataset abstract

The city plan is a general plan of the organisation of land use and traffic. Helsinki’s new city plan (2016) covers the entire city, with the exception of Östersundom. The city plan is drawn up in Helsinki approximately every ten years.

The city plan facilitates Helsinki’s growth into a dense city where the several centres are linked together by rail transport. For example, Malmi, Itäkeskus, Herttoniemi and Kannelmäki can grow into new urban centres that provide versatile housing, services and employment options.

The new city plan will create prerequisites for expanding the inner city, for example along the roads Vihdintie and Tuusulanväylä, which will be changed into city boulevards. In this city plan, Helsinki is still a green city, and its urban forests and cultural environments are its strengths. Helsinki Administrative Court and the Supreme Administrative Court of Finland repealed certain parts of the city plan. The repealed notations apply to elements such as the city boulevards of Länsiväylä, Turunväylä, Hämeenlinnanväylä and Lahdenväylä as well as certain areas around Viikintie and in Tuomarinkylä, Pornaistenniemi, Vartiosaari, Ramsinniemi and Ilmala. The 2002 master plan will remain in effect in these areas. The areas are indicated in the master plan map.

The 2016 city plan became legally valid on 5 December 2018. There is also an underground master plan in force in Helsinki (approved in 2011) and a number of component master plans.

The purpose of the city plan is to provide general guidance on the community structure and land use of a municipality or part of it and to coordinate operations. The city plan sets out the principles of the desired development and indicates the necessary areas for detailed city planning and other planning as well as for construction and other land use. The municipality is responsible for the preparation of the city plan. The plan is approved by the municipal or city council.

History

The first land use plan for Helsinki was drawn up by town planner Bertel Jung in 1911. Helsinki's next plan on the master-plan level was the Pro Helsingfors plan from 1918, prepared jointly by Eliel Saarinen and Bertel Jung. In 1932, a “detailed master plan” was approved, which was a master-plan level plan.

The current kind of master planning started with the 1960 master plan, which was the first master plan to cover the whole city after the wars. Its preparation started in 1953. The next master plan proposal was published in April 1970, and it was supplemented by a component master plan for the city centre adopted in 1976. After the lively master planning period of the 1970s, there was a pause in Helsinki’s master planning.

The 1992 master plan has had far-reaching effects on the city structure in Helsinki. At that time, the construction of a new harbour in Vuosaari was proposed. In 1992, a land-use development image was also drawn up for the first time. For example, the 2002 master plan included areas to be released from harbours: Kruunuvuorenranta, Kalasatama and Jätkäsaari. Indeed, it offered a significant potential for urban development. The preparation of the new city plan began in 2012.
