West Quesnel Land Stability Project

The Uplands area of West Quesnel is experiencing impacts from ongoing ground movement. This movement has been occurring over a long period of time and is very slow, about 14 mm in 2016. The effects on buildings and civic infrastructure vary with location but can be significant.

Overview

The City of Quesnel is committed to develop and implement measures to reduce the movement to manageable levels and has given its highest priority to the West Quesnel Land Stability Program.

From 2006, the Province of BC, Federal Government and the City of Quesnel committed significant financial contribution to the West Quesnel Land Stability Program.

The area of West Quesnel impacted by the ground movement includes an attractive, established residential community. About 940 parcels of land, 750 homes one elementary school and several businesses are included in the study area.

The total value of the land, improvements, services and infrastructure in the West Quesnel study area exceeds $100 million. West Quesnel is important to the economic and social viability of the City of Quesnel and is home to almost 25% of the City’s population.
