Funding was provided with the regional planning contract of 1984. The project, re-estimated to cost 520 million francs (about 79.3 million euro or 103.5 million US dollars), received 50% of its funding from the state, 42.8% from the region and 7.2% from the "département", the latter covering the extra cost of building a tramway over other transportation options. The public consultation took place in July 1984 and in August the result was response was published as being favourable. The RATP became in charge of operating the new line and it was declared to be a public utility on 19 December 1984. Construction was estimated to be completed in 1988. Ultimately responsibility for the project was adopted by the STIF with some minor modifications in October 1985, resulting in a final price tag of 535 million francs before tax (about 81.56 million euro or 106.48 million US dollars). With these final modifications, the line was aimed towards the commune of L'Île-Saint-Denis. The line would have to cross the commune but opposition at the time from the Hauts-de-Seine General Council caused the line to end at Saint-Denis railway station.
