In 2100 Lillestrom will feature renatured and mixed-use areas. Its construction will be split into two independent phases. The first one will begin with the creation of a buffer area, by intervening on blue and green infrastructure, together with a in-fill process acting on Nesa’s built environment, with the purpose of preserving industrial enterprises, nesting services and public spaces.
Nesa will become a self-sufficient neighborhood, lively over the whole day, inter-generational, multi-purpose and resilient to future challenges. During the second phase, the project area will be the target of different actions: on-site purification of contaminated soils, fusion and reuse of the pre-existing architecture and the construction from scratch of different typologies.
The design of blue infrastructure belongs to a resilient approach to extreme events: riverbanks, flood plains and discharge-drainage canalization are examples of measures to drain water towards specific zones.When operating along a river such elements have large volumes.Conversely, they will be tiny and will diffuse over the whole project site.The design will be aligned to the local topography, in order to reduce costs and smoothen their operation.
The design of green infrastructure, implementing the blue one, consolidates and expands the indigenous flora and connects the new urban district to the surrounding natural reservoirs.This will generate micro-economies tied to the timber industry and to rural tourism. Together, blue and green infrastructure, acting as mitigation measures, can stock CO2 emissions, purify contaminated soils and increase biodiversity.They generate a troisième paysage with a strong identity, which, despite not being immediately accessible, is nevertheless necessary for the recovery of soils, fostering the kick-off of profitable scientific research activities.These strategies are merged with those targeted at discouraging car use in favor of soft mobility, introducing intermodal solutions and a different road design: traffic calming area, cycling streets, woonerf within the new urban context.
The new environmental and mobility infrastructure play a strategic role already in the first phase, binding currently fragmented areas.The new urbanization generated by phase 1 actions will be set on this initial framework. The segmentation of the project on differing timeframes is a cost-efficient way to target the critical aspects identified in the area.
