The 2020-2030 Conservation, Design and Development Management Plan for Parc Jean-Drapeau is a 680-page reference work resulting from a vast multidisciplinary effort, combining a citizen-based approach with the creation of a design vision. Its scope is consistent with the enormous potential of this large urban park, and reflects the commitment of the Société du parc Jean-Drapeau to make a sustained effort to showcase the park’s natural, cultural and built heritage. By innovating to stand out, implementing an organizational shift, listening to residents and offering distinctive experiences to local and visiting users, the plan targets the challenges of the coming years in order to position the park as the jewel of Montreal’s parks. The plan proposes new promenade experiences, direct dialogue with the waterways, a variety of landscapes, universally accessible spaces, improved mobility, resilient amenities, rehabilitated heritage elements and distinctive visual signatures. The plan is an indispensable tool for making the vision a reality, by serving simultaneously as a repository of data related to the park, a guide to planning and design actions, and an implementation document.
