Integrated Storm Water Management


Climate change has led to more frequent and intense storm and rainfall events along with increased flooding, storm water runoff, and soil erosion. These are forcing planners and storm water specialists to develop strategies dealing with greater volume and velocity of storm water. At the same time, urban areas are densifying and land is more covered with sealed surfaces.

As the Baltic Sea region is estimated to face more frequent and heavier rainfalls, the current planning and management practices have proven to be weak in meeting these challenges. Thus, the project idea is to create higher quality, cleaner and safer urban environment and increase urban sustainability.



To reach its goals, the project develops guidelines and tools for Integrated Storm Water Management and introduces the practices into urban planning process. This is done, for example, through the science-practice collaboration, aiming to find and elaborate common management methods. The project establishes local support groups within all partner cities enabling municipalities to develop their solutions in close collaboration with local stakeholders and various community interest groups.

  • Within the project a student competition is organised to find and develop new, innovative, applicable to BSR conditions storm water management solutions for 7 partner cities, which later will function as basis for investment plans to be realized after the project life-time
  • Partner cities create/update their urban and storm water planning processes and storm water programs/plans which will set targets and actions for SW management for the upcoming years
  • Project consortium develops Guidelines for Integrated Storm Water Management, which illustrate an ideal ISWM system taking urban planning processes permanently to the new level
  • Project consortium also develops the evaluation criteria for a peer review to be further disseminated and used in practice in cities within the BSR and the EU
  • During the project’s time-life more cities are trained to use the Integrated Storm Water Management system and the Green Area Factor tool


Consequently, local management practices are improved aby the Integrated Storm Water Management approach which will link all the urban planning processes and stakeholders. In practice, the project partner cities adopt new programmes and approximately 35 other cities are trained to use developed methods in the region. In addition, the outcomes of the student competition will lead to construction or investment plans. Thus, urban planning is taken to a higher level by developing, localizing and piloting new tools in the Central Baltic region.

Improving urban planning by developing integrated and multifunctional storm water management in the Central Baltic cities.
