In September 2006 , the Government of Croatia formed a construction workgroup . It was decided that the project , estimated at the time at HRK 173 million ( US $ 30 million ) , would be partially financed by the Government of Croatia and the City of Zagreb , and that both Jewish organizations should be represented in the workgroup . However , the involvement of Bet Israel was deemed unacceptable by the Jewish Community of Zagreb , which is the sole owner of the Praška Street property , and which also see itself as the sole legal representative of the Zagreb Jewish community . As a consequence , the community and its president , Ognjen Kraus , refused further participation in the project under the set conditions .
