Abstract
Erosion of the cliffs at the Point Grey Peninsula threatens important infrastructure and buildings at UBC. In order to tackle this problem, UBC launched a comprehensive project called Living Breakwaters. This project is part of Living Breakwaters and aims to act as a transversal element among different expertise, integrating these specializations into a holistic framework. It analyses the problem from a technical, environmental, economic, legislative and social perspective. Four concepts are proposed to tackle the erosion and their key feasibility issues are identified. Accordingly, the main goal of this report is to present a clear and holistic framework of the erosion problem at the Point Grey cliffs, both gathering and integrating existing information and contributing with innovative ideas that might open new approaches for dealing with erosion. In conclusion, the Point Grey cliff erosion is a problem that has to be tackled to prevent severe damage to the adjacent lands. It is advised to combine both marine and subaerial measures. An integrated approach combining technical, environmental, legislative and social expertise is recommended in order to achieve a truly sustainable design.
