This report gives a summary description of the ISLANDR Roadmap and its components. The ISLANDR Roadmap is a decision-making tool designed to support users engaged in contaminated site management and land redevelopment. Recognising the complexity of the remediation process, the roadmap does not prescribe a rigid set of steps but instead offers structured guidance to navigate key decisions. While it cannot map every possible choice in advance, it provides a clear direction to help users make informed and effective decisions. Adaptable to different contexts, the roadmap can be tailored to deliver user-specific insights, ensuring relevance and practical value for diverse remediation projects. The Roadmap consists of three journeys: single sites, portfolio of sites and diffuse soil contamination, and those journeys are described in separate reports.
