The Arrondissement Government of Côte-des-Neiges—Notre-Dame-de-Grâce invited Concordia University and Université de Montreal to collaborate in the redesign of two sites in two parks in this district – Kent Park and Notre-Dame-de-Grâce (NDG Park). Under the coordination of Silvano De la Llata and with students as facilitators, the methods of planning-in-situ and open planning were tested for the first time in this two parks. After a thorough analysis, intense collaboration with the borough government and two community charrettes we learned that interactivity, versatility and social permeability were the most important values to enhance this parks as well as that stakeholders largely liked their parks as they were. Therefore it was proposed that the sites were enhanced and turned into community platforms that citizens could appropriate and adapt according to their needs. The ideas produced in these exercises were later partially adopted and adapted by design firms and the city. These two sites have been built and soon will be inaugurated.
