In geometry a golden spiral is a logarithmic spiral whose growth factor is related to the golden ratio. A golden spiral gets wider by a factor of φ for every quarter turn that it makes.
The golden ratio is found all throughout nature, in plants, animals and even in the human body. One of the most common examples of the golden spiral in nature is the shell of the Nautilus. Artists and architects have used it to proportion their works, in architecture the the golden rectangle, where in the ratio of the longer side to the shorter is based off of the golden ratio has been used for centuries. Notable examples include Michealangelo’s works, classical Greek temples and the Great Mosque of Kairouan. Le Corbusier utilized its proportions for his modulor system.
The Golden Spiral City plan utilizes, cycle paths and pedestrian greenways, canals, a light rail transit network, a street network and a major urban boulevard for access to the central core. As one approaches the city centre the block sizes get smaller and densities increase. The cycle paths and pedestrian greenways are shown in green, the Light Rail Transit network in red. The blue indicates the canal network, the light black the street network and the dark black shows the graceful curve of the boulevard into the central area.
The cycle paths and pedestrian greenways allow residents to use active transportation to move through the city. Providing an extensive network of seperated bicycle paths and pedestrian walkways. These routes also create a series of linear parks that thread through the city leading to larger green spaces at the intersection of the pedestrian routes.
In order to keep these paths active and safe they are designed with lane-way style housing and studio spaces. This achieves two goals, by keeping eyes on the street the pedestrian network doesn’t become a dangerous place after dark by insuring that there will be traffic from residents. These types of housing and studio spaces are also intended to keep the selection of rental spaces diverse and accessible.
