Low impact development and decisions: a framework for comparison of spatial configurations low impact development in the design of a district

This study analyzes the quantifiable impacts of low impact development features, sometimes referred to as green infrastructure, across three alternative proposals for the development of a city district along the edge of a lake and a creek. Low impact development is defined as a stormwater management approach designed to capture water before it goes into stormwater drains or directly into bodies of water in order to allow the water to infiltrate groundwater sources or evapotranspirtate back into the atmosphere. The study applies Carl Steinitz’s Framework for GeoDesign to the three alternative proposals and the existing conditions as a means of comparison in order to understand an informed decision based approach to design.
