with the idea of constructing linear sections of infrastructure - roads, railways, gas, water, etc.- along an optimal line and then attaching the other components of the city along the length of this line. As compared to the concentric diagrams of Ebenezer Howard and other in the same period, Soria's linear city creates the infrastructure for a controlled process of expansion that joins one growing city to the next in a rational way, instead of letting them both sprawl. The linear city was meant to ‘ruralize the city and urbanize the countryside’, and to be universally applicable as a ring around existing cities, as a strip connecting two cities, or as an entirely new linear town across an unurbanized region. The idea was later taken up by Nikolay Alexandrovich Milyutin in the planning circles of the 1920s Soviet Union. The Ciudad Lineal was a practical application of the concept. Regional planning movement Patrick Geddes (1864-1932) was the founder of regional planning. His main influences were the geographers Élisée Reclus and Paul Vidal de La Blache, as well as the sociologist Pierre Guillaume Frédéric le Play. From these he received the idea of the natural region. According to Geddes, planning must start by surveying such a region by crafting a "Valley Section" which shows the general slope from mountains to the sea that can be identified across scale and place in the world, with the natural environment and the cultural environments produced by it included. This was encapsulated in the motto "Survey before Plan". He saw cities as being changed by technology into more regional settlements, for which he coined the term conurbation. Similar to the garden city movement, he also believed in adding green areas to these urban regions. The Regional Planning Association of America advanced his ideas, coming up with the 'regional city' which would have a variety of urban communities across a green landscape of farms, parks and wilderness with the help of telecommunication and the automobile. This had major influence on the County of London Plan, 1944. City Beautiful movement The City Beautiful movement was inspired by 19th century European capital cities such as Georges-Eugène Haussmann's Paris or the Vienna Ring Road. An influential figure was Daniel Burnham (1846-1912), who was the chief of construction of the World's Columbian Exposition in 1893. Urban problems such as the 1886 Haymarket affair in Chicago had created a perceived need
