Dominica’s coastal areas have experienced severe flooding during recent heavy rainfall and tropical storms events due to the rapid movement of water from the upland areas to its coastal plains and lack of adequate floodwater storage areas. Fundamentally, as part of an integrated stormwater management approach, the related main engineering issues and interrelated challenge include rapid surface water flow associated with severe rock and mud debris that have produced significant damages to local roads, facilities, and endangered offshore protected fauna and flora. Cost-effective and affordable engineering solutions were implemented in Dominica and other Caribbean countries to mitigate negative environmental impacts of low-volume road (LVR) investments, improve operation and maintenance activities, and minimize coastal flooding. Solutions included improving stormwater flow conveyance systems and incorporating flow retention and debris–rock trap facilities. Near-shore water quality preservation activities included controlling surface water flow through specific retention measures and source treatment in terms of modification and improvements of land use practices.
