Practical Guide to Implementing Green-Gray Infrastructure

Practical Guide to Implementing Green-Gray Infrastructure describes tools, experiences, and techniques to implementing green-gray infrastructure to increase the resilience of vulnerable communities. The guide provides information about many aspects of green-gray infrastructure, including identifying, funding, financing, planning, designing, constructing, and monitoring green-gray infrastructure projects. These tools and case studies have been collected based on experiences of members from the Global Green-Gray Community of Practice. The Practical Guide is intended to be used as a resource for selecting, funding, designing, and constructing green-gray infrastructure projects, as well as a tool for education and outreach.

Increasing Infrastructure Resilience with Nature-based Solutions (NbS): A 12-Step Technical Guidance Document for Project Developers is specifically for public and private project developers in Latin American and the Caribbean, but other audiences may also find it useful. This guidance helps developers consider how to incorporate nature-based solutions into their project planning from its earliest stages, also emphasizing opportunities for stakeholder engagement and adaptive planning and management throughout. It addresses not only engineering aspects of nature-based-solutions initiatives (i.e., technical assessments, design, implementation, and operations and maintenance [O&M]) but also steps related to governance, economic assessment, financial structuring, and permitting.

Guidance for Considering the Use of Living Shorelines describes the role of the National Oceanic and Atmospheric Administration (NOAA) in implementing living shorelines and the science, tools, and training the agency uses to guide these projects. The conceptual framework included in this guidance aims to help NOAA and its implementation partners determine if a living shoreline is an appropriate solution and plan shoreline stabilization projects. The guidance describes NOAA’s living shorelines guiding principles and “highlights NOAA’s role in providing science, tools, and training to help inform the selection of appropriate techniques. It also discusses the agency’s role in reviewing living shoreline projects” (4) and offers a conceptual framework of 12 questions to help plan a shoreline stabilization effort.
