Alternative Methods And Forums To Optimize Public Participation In The Planning Process, Joseph James David

Master's Theses

“Public participation” takes on various forms in the realm of local government planning. Many planners stand behind the ideal of involving community, but participation in practice often fails to achieve this objective. The primary vehicle for local government participation is the public hearing, which is a formalized process that often elicits one-way communication from planner to public. The nature of a hearing is to inform the public about development applications or policy changes, expose governing body decisions to the public, and elicit reactions from interested members of the public. Significant effort is taken daily by local planning departments to promote …
