LID in a Canadian Residential Brownfield Re-Development

摘要

The release rates from the Currie Barracks Phase 1 re-development (brownfield site into a medium density residential site) in Calgary, Alberta are required to match pre-development flows. In order achieve these release rates AMEC developed a Low Impact Design (LID) approach to stormwater management. Some of the key issues that AMEC resolved throughout this process were the impacts of the unique climate dominated by freeze-thaw events during winter months and the impacts of freezing on infiltration facilities.
