Planning management by the landslide in Stenungsund : Analysis of the planning process for the area affected by a landslide in Stenungsund in 2023. (English)
Abstract [sv]

Detta kandidatexamensarbete undersöker detaljplaneprocessen för detindustriområde som planerats och anlagts på fastigheten Munkeröd 1:12 m.fl. i Stenungsunds kommun, där ett jordskred skedde i september 2023. Undersökningen gjordes genom en dokument- och litteraturstudie samt en intervjustudie. Resultatet tyder på att kommunen gjort flera tveksamma riskbedömningar avseende den geotekniska säkerheten. Bland annat togs viktig information gällande den bedömda stabiliteten för planområdet bort och en felaktig bergskarta låg till grund för områdets lastbegränsningar. Dessa bedömningar ochbeslut tros ligga till grund för att skredet skedde.

Analysen av detaljplaneprocessen visar på behovet av att under den långa processen behålla kontinuitet och noggrannhet. Vidare belyser arbetet nödvändigheten av ett nära samarbete med utomstående experter, särskilt inom geoteknik, samt myndigheter för att möjliggöra för adekvata riskbedömningar. Dessutom krävs e nöppen dialog med berörda parter och en systematisk grundlig hantering av riskerna genom hela planprocessen.

Sammanfattningsvis visar arbetet värdet av att integrera riskhantering på ett effektivt sätt i detaljplaneringen för att skapa robusta och hållbara samhällen. Genom att dra lärdomar från tidigare erfarenheter, som skredet i Stenungsund, kan vi förbättra planeringsprocessen och på så sätt minska risken för framtida katastrofer.

Abstract [en]

This bachelor's degree project examines the planning process for the industrial area planned and constructed on the property Munkeröd 1:12 in Stenungsund Municipality, where a landslide occurred in September 2023. The investigation was conducted through a documentand literature study, as well as through an interview study. The results indicate that the municipality made several questionable risk assessments regarding geotechnical safety. Forexample, crucial information regarding the assessed stability of the planning area was removed, and an incorrect bedrock map was used as the basis for the load limitations in the area. These assessments and decisions are believed to have contributed to the landslide.

The analysis of the planning process highlights the need to maintain continuity and thoroughness throughout the long process. Furthermore, the degree project underscores the necessity of close collaboration with external experts, especially in geotechnics, as well as government agencies to enable adequate risk assessments. Additionally, an open dialogue with interested parties and a systematic, thorough handling of risks throughout the entire planningprocess are required.

In summary, the degree project demonstrates the value of effectively integrating riskmanagement into the planning process to create robust and sustainable communities. By learning from past experiences, such as the landslide in Stenungsund, we can improve the planning process and thereby reduce the risk of future natural disasters.
