project despriction – “Mainzelbahn“
Important factors of cost increase
• Until cost calculation− Price trend− Adaption of plans
(citizen participation process, …)− New insights (cable network)
• During building− Cables, pibes and cable-pibes− consistency of the soil despite expert‘s reports− Stringent official conditions, approval costs− External influences

citizen participation – initial situation
representative telephone survey (2010) for tram-expansion
majority of citizens support the “Mainzelbahn“ project different acceptance in discricts
positive negative undecided
20.05.2019 13
citizen participation – initial situation
critical votes at the beginning
“NIMBY-symptom“
• too expensive, wasting public money
• no necessity, uneconomical, harmful to the environment and
cityscape
• it is better to invest in a zero-emission bus service
• health hazard because of airborne noise and surface shaking
• depreciation for neerby properties
→additional specific challenges
20.05.2019 14
citizen participation – concept
methods of partizipation and communication during the planning phase
• voluntary public participation and information events
• participation and information during the construction liceningprocedure
• offer for talk with politicians, public-administration, business representatives, interest groups, …
• public relation activities
activities in public relation
• “Mainzelbahn“ branding for a positive project image
• developing a internet presence
• print media
20.05.2019 15
citizen participation – concept
schedule of citizen participation during the planning phase
conception consolidation elaboration
application of the construction licening procedure
Public inspection of the planning area
Citizen information
20.05.2019 16
citizen participation – workshops
task / challange
• objectification of discussion
• early realization and reduction of conflict situations
• transparency of planning and decision proceses
• confirming acceptance for the project and the project executing company(MVG)
• learn about determing factors in different districts and environments and making the planning better by knowing them
• knowledge about arguments for the construction liceningprocedure
20.05.2019 17
citizen participation – workshops
dialog between planners, MVG representatives and citizens
requirement / prerequisite
• external moderator
• seperate workshop in every district
• all workshop members discuss in an open and unbiasedway
• no replacement of workshop members → continuity
• no debates on principles
• “what is the best design of the line, when the city council votes for the project“
• citizen participation is not a referendum
20.05.2019 18
citizen participation – conclusion
• more proximity to citizens
• more quality and sustainability in planning
• synergy between the different methods of communication and participation
• the willingness of the MVG for modification of the planning
• great majority for realising the project in the city council
• only 50 objections during the construction liceningprocedure
• no dispossession although 300 realties were needed
risks
• different political majorities during the project / planningphase
• citizen paticipation leads to a debate of principles
• politicians do not accept the undependence of the citizen participation process
• the project executing company is not willing to compromise on alternatives
