The communities of Marchand and Entrepot border one another and are located in Castries to the south-east of the city. The Marchand-Entrepot River is a tributary of the Castries River which traverses these communities on its way to the sea through the city of Castries. The Marchand-Entrepot riverbank stabilisation works aim to address soil erosion which has created bank slope instability along the banks of this tributary, increasing the risk of land slippage along a densely developed area with existing structures lining the riverbank.
