Following a detailed analysis of economic, social and environmental factors, we’ve worked with the client to produce a flood study to understand and quantify flood risk for Campbeltown and protect its community from the increasing threat of flooding.
A review of historic information indicated Campbeltown was at risk of flooding from multiple sources. To tackle this, we used our ICM skills to build a 1D-2D linked integrated catchment model of watercourses, drainage network, direct rainfall and tidal interaction, which enabled us to design a holistic flood scheme and appraise options to manage both fluvial and pluvial flood risks simultaneously.
The project included the development and appraisal of options and selection of a preferred option for promotion, design and construction. A robust optioneering exercise was undertaken and over 30 potential options were developed, with feasibility assessments used to shortlist options. Stakeholder engagement was a significant part of this process, with SEPA, Scottish Water and Scottish National Heritage consulted at multiple stages. We also delivered extensive public consultation and early landowner engagement. A full options appraisal, including economic, social and environmental assessments, was carried out which informed the selection of a preferred solution comprising of upstream storage, culvert upgrade, SuDS retrofit and Property level Flood Protection (PFP).
