During a well-attended Stadslab Maashaven meeting, the participation process around Park Maashaven was started. The designers of SWA / Balsley and Arup have presented three different models. Much valuable information has been collected from residents, entrepreneurs, initiators and institutions. The Stadslab meeting is the start of a series of meetings in the coming weeks. All input is collected in a response document and included in the final design of Park Maashaven, one of the BigFive projects for more green in Rotterdam.
