Stockholm Extended Metro: Nacka/Södermalm/Söderort21st December 2021 by Alexander Soldatikhin

A major success has been that the project has involved the local community and stakeholders throughout the planning process.

Consultation has been conducted in several stages and shaped in order to reach those most affected and concerned. Consultations have been held in several places along the location of the Stockholm Metro extension and have also been conducted digitally through emails and newsletters, as well as exhibited documents at Region Stockholm and the municipality’s premises. Consultation documents have been published on the website and a link has been published in an advertisement and in mail letters.

Comments are communicated in writing and all opinions are evaluated by the project team to determine whether it entails revisions of the design work or regarding working methodology/implementation. Views are summarised and responded to in a consultation report which is published on the web so that the public can take part in the responses.

The process for choosing the location of the project has been extensive and has included many different factors and conditions. The new stations for the Stockholm Metro extension have been placed to be accessible to future passengers, while we strive to have as little impact as possible on the environment and human health during the construction period. This has been achieved through the JP process, which provides an opportunity to weigh different alternatives against each other and land on a solution that provides benefits for the residents.

It is challenging to build in a city with significant cultural heritage and history, such as Stockholm. The project has integrated previous investigations with extensive further investigations and inventories regarding the historical environment, to determine how it is affected and how this can be minimised. Checks are carried out continuously throughout the process.

As far as possible, the project has avoided affecting the valuable natural environment. To this end, the team have carried out investigations and produced inventories to map protected animal and natural environments. Further, specific requirements have been set where there is a need for special handling.

The legal process for the environmental permit has meant that the project has strict requirements to comply with regarding groundwater impact. Homes and business located within the project’s immediate environment are inventoried based on their sensitivity to groundwater lowering, and groundwater levels are continuously monitored in accordance with a comprehensive control program and maintained if necessary via infiltration.

The Stockholm Metro extension is a sustainable transport project that expands the public transport opportunities within the region. The project increases the resilience of the region’s transport system by relieving the existing system and offering new itineraries.
