Conditions for Koprivnica to start its SUMP process were mixed.On the one hand, national guidance and knowledge on SUMP processes were scarce. In fact, when it eventually adopted its SUMP in 2015, Koprivnica was the very first Croatian city to do so, which highlights the City Administration’s pioneering approach. To make the SUMP work, a change in planning culture and capacity creation was required. Work on the SUMP was largely based on the European Commission’s guidelines.On the other hand, Koprivnica could base its process on previous efforts to foster sustainable urban mobility, such as the working group on sustainable urban mobility from the European Mobility Week.The SUMP working group, which was developed from the working group for the European Mobility Award, included City Administration and political representatives alongside stakeholders from schools, kindergartens, public and private enterprises, environmental and mobility non-governmental organisations (NGOs), and media. The SUMP was adopted on 17 July 2015 by the City Council including a clear allocation of responsibilities, funds and resources. One specific task of the SUMP was to cater for training and capacity building of the staff involved to prepare for the actual implementation. A SUMP competence centre called the Southeast Europe Competence Centre on Sustainable Urban Mobility Planning’ was created to – among other things – foster good monitoring and evaluation of the SUMP implementation.
