Balancing Growth and Conservation: The potential of Density Transfer Modelling in Bowen Island's Urban Planning

Ran,Guangxiu

The rapid population growth in British Columbia has led to the necessity of innovative housing solutions. Local municipalities in BC, such as Bowen Island, are exploring the implementation of Density Transfer Modelling (DTM) as a planning tool to address these challenges. The study examines Density Transfer Modelling by Geographic Information System (GIS) application on Bowen Island, managed under the Islands Trust Act, to balance development with ecological preservation. This involves identifying "donor" sites (areas of high ecological value with existing development) to transfer development rights from, and "receiver" sites (areas suitable for increased urban density) using the Normalized Difference Built-up Index and residential density classifications. Two main Comprehensive Development Areas (CDAs) on Bowen Island, Arbutus Ridge and Snug Cove are highlighted. The DTM calculates that this area supports the development of up to 30 additional detached homes in Arbutus Ridge Development Area. The Snug Cove Comprehensive Development Area (Snug Cove CDA) has been identified as a key area for increased residential development with a focus on increasing affordability and creating a pedestrian-friendly environment. According to DTM calculations Snug Cove Residential Area supports the development of 2186 dwelling units. The goal of the Snug Cove Development Area is to build a variety of housing types, including duplexes, triplexes, and multi-unit buildings, clustered near essential services and transportation hub(ferry). Both CDAs exemplify how density transfer modellings can be effectively utilized within designated development areas to support sustainable urban planning goals.
