Implementation plan

Adaptative and incremental approach

For the Grilstad community the implementation plan is oriented towards an incremental approach with the objective to create an adaptable community capable of functioning even in the extreme event of a rise in sea level, the plan is built around a short-, mid-, and long-term strategies, taking advantage of the financial resources available to create a guideline for similar type of developments.

Short Term

Starting after the implementation of the “immediate plan”, this strategy is based on building the community as an entity capable of organizing itself in case of a hazardous event, this is especially important in Grilstad since is a young community not older than 4 or 5 years, information will be provided to the residents about the possible situations that a rise in sea levels could cause in the area, pointing out gathering safe zones and conducting rescue drills to reduce possible injuries or obstructions that could affect the effectivity of the first responders.

Floating walkways

Studying the example from Venice where elevated walkways are used to provide mobility for pedestrians when in high waters, in Grilstad a variation of this approach is proposed as floating walkways, used to establish new connections to the mainland allowing people and first responders to access the area in case the normal routes of access are compromised, or new ones are required to improve mobilization and rescue efforts. For this strategy, a previous study of the area helps us to identify the best placement for the floating walkways ensuring easy access to them.

Mid Term

Adaptable Landscape

Similar to the water squares in Rotterdam, this approach proposes the creation of a public space network capable of holding water, to implement this strategy the current public spaces on site (gardens and children’s parks), are replaced with pools that will keep their functionality as public space while adding the capacity of holding water, preventing walkways to be affected by the flood.

The aim of this approach is to generate adaptability, allowing the community to function “normally” even after experiencing this type of event.

In addition to this, removable flood barriers could be installed in front of underground garages to prevent damage.

Community activities like gardening help create a network among residents while also allowing them to communicate

Long term

This phase constitutes a vision for the future of the Grilstad area, expanding on the context of the man-made island, an extension of this project that aims to add artificial land surrounding the island,

Storm surge protection through a network of green open spaces for public use, uses nature based solutions creating a new coastline of parks and public space capable of reducing the effects of storms surges and mitigating the effects of flooding while improving the urban environment.

Community activity open green areas for food gardens, play parks that become pools of water during flooding

The vision for Grilstad and future projects with a similar concept is one where artificial land is created not only to serve as opportunities for new urban development but also as protective barriers

Water squares: these are a network of open public space that become water pools during flood times. This mimics the natural topography of the Trondheimsfjorden that can prevent the consequences of flooding to affect them and already established urban entities while preserving a high level of functionality in the worst-case scenario.
