FEMA's geoplatform, including its geospatial resource center, facilitates information sharing between the federal government, NGOs, and the public. It includes geospatial data on hurricanes, floods, wildfires, and several other hazards that can be used for visualizing, siting, and exploring potential NBS implementation sites. 

FACT (Financing Alternatives Comparison Tool) is an easy-to-use financial analysis tool that
compares the costs associated with various financing options for water infrastructure and
water quality projects. There are two versions of the tool - FACT standard, which provides comprehensive analyses, and FACT Lite, which offers simplified analyses for high-level cost comparisons.

This best practices guide illustrates a variety of incentives states use to encourage consideration and implementation of green infrastructure (as well as other NBS adoption strateges) and foster sustainability within their programs.

The USGS Flood Inundation Mapping (FIM) Program helps communities protect lives and property by providing tools and information to help them understand their local flood risks and make cost-effective mitigation decisions. Its main purposes are to 1) Partner with local communities to assist with the development and validation of flood inundation map libraries and 2) Provide online access to flood inundation maps along with real-time streamflow data, flood forecasts, and potential loss estimates.

This checklist includes overall strategies to improve flood resilience as well as specific strategies to conserve land and discourage development in river corridors; to protect people, businesses, and facilities in vulnerable settlements; to direct development to safer areas; and to implement and coordinate stormwater management practices throughout the whole watershed.

Resource library that provides managers with best practices for managing forests within urban areas as opposed to street trees or landscaped parks.

This report identifies various funding sources that can be used to support stormwater management programs or finance individual projects. This includes financing options for individual projects and larger-scale programs, examples of existing muncipal programs and a resource list to further explain opportunities.

This database is a compilation of literature resources documenting the effectiveness and economics of nature-based solutions and green infrastructure for coastal resilience.

*Includes: Stormwater Management Model (SWMM), National Stormwater Counter (SMC), Green Infrastructure Wizard (GiWizard), Watershed Management Optimization Tool (WMOST), Visualizing Ecosystems for Land Management Asessment (VELMA) Model, Green Infrastructure Flexible Model (GIFMod), Community-enabled Lifecycle Analysis of Stormwater Infastructure Costs (CLASIC) Tool, and the Integrated Decision Support Tool (i-DST)

This guide is an abridged version of a longer guide available by request through NOAA's Office of Coastal Management. It summarizes the most common green infrastructure practices and how they may reduce flood risk, provides planning/implementation considerations, and a helpful chart to estimate an interventions water storage potential and associated costs.

This toolkit provides basic information about green roofs, their benefits, installation considerations, and maintenance needs.

This webpage provides information on how to implement green roofs on historic buildings, specifically within the NPS.

EPA's Healthy Watersheds Program vision is to protect and maintain the aquatic ecological integrity of watersheds and supporting habitat networks to ensure that future generations may enjoy these resources and the social and economic benefits that they provide.The site includes several resource to design outreach plans, locate existing watershed restoration projects, and guidance on developing a watershed health index to evaluate your own watershed. 

This report reviews a vision for designing a road network that incorporate WRCS for human and wildlife benefits. It includes a description of common challenges faced when installing these structures.

FEMA's Community Rating System can be used to offer communities credits to reduce policyholders' flood insurance premiums when appropriate flood risk reduction measures are taken. One way to earn credits is through floodplain (open space) conservation. This guide explains how to earn credits in areas already under protection agreements and ways to earn additional credits.

This guide provides step-by-step instructions to assist communities in implementing nature-based solutions and is especially useful for Community Planning and Development Fund recipients.

This toolkit is a guide that helps recipients of HUD Community Planning and Development (CPD) funds identify opportunities to use their CPD dollars to mitigate the impacts of natural related hazards. The toolkit is divided into 6 separate sections, each related to a specific natural hazard. Each section provides an overview of the natural hazard as well as suggestions for different mitigation techniques that are eligible under different CPD programs. Additionally, the toolkit has a financing section with other funding opportunities for resilience projects.

Software that provides tree benefit estimation science through various tools and support.

This short document links to a series of resources and tools that can be used to incorporate watershed planning and green infrastructure priorities into State Hazard Mitigation Plans.

Explains how built wetlands function, project design, construction, operations, and monitoring.
