Environmental Due Diligence
The EDR® Radius Map Report with GeoCheck® helps environmental professionals evaluate available environmental records for a target property and surrounding area as part of Phase I ESA, transaction screen, desktop review, and related environmental due diligence workflows. Long recognized as a core records-review resource, Radius Map brings together federal, state, tribal, local, and proprietary environmental data in a mapped, searchable format that supports ASTM E1527-21 and EPA All Appropriate Inquiries workflows. With current source documentation, ASTM-aligned search distances, GeoCheck physical setting context, and LightBox Live access, users can move from large volumes of records to a clearer understanding of environmental conditions around the property.
Review available environmental records for the target property and surrounding area, including federal, state, tribal, local, and proprietary sources that support environmental due diligence workflows.
Organize records around ASTM E1527-21 records-review concepts, including approximate minimum search distances, source documentation, and data currency tracking, with options to adjust search requirements by scope where applicable.
Use environmental records maintained through ongoing source relationships and regular data updates, with source and currency information included to support documentation and transparency.
Improve review confidence with LightBox AI-powered geocoding, which uses a foundation of more than 267 million validated address points to help place environmental records closer to real-world property locations and reduce review friction.
Review Radius Map results alongside property, parcel, map, and environmental context in LightBox Live, helping users move more efficiently from records review to site insight.
Every EDR® Radius Map Report with GeoCheck® includes environmental record research, mapped and unmapped record context, physical setting information, and access options designed to support Phase I ESA and environmental due diligence workflows.
Searches available federal, state, tribal, local, and proprietary environmental record sources for the target property and surrounding area.
Includes EDR High-Risk Historical Records that help identify past uses such as gas stations, dry cleaners, and manufactured gas plants that may not appear in current government record searches.
Includes Government Records Searched / Data Currency Tracking so users can see which sources were searched and the available currency information for those sources.
Results are organized around the target property, surrounding sites, and available search distances relevant to the project scope.
Standard records review is organized around ASTM E1527-21 approximate minimum search distance concepts, with customizable distances available where project requirements call for a different scope.
Mapped records include available map ID, distance, direction, relative elevation, and database context. Orphan / unmapped summaries identify records that cannot be reliably plotted due to incomplete or insufficient address information.
GeoCheck adds topographic, hydrologic, hydrogeologic, wetland, flood, soil, and geologic information to help users evaluate site conditions and potential contaminant migration considerations.
Review Radius Map results within an interactive project workspace with map layers, content layers, parcel context, data tables, and report access.
For project documentation and inclusion in due diligence deliverables.
Structured data file for sorting, filtering, and inclusion in custom review tables, where available.
Use map and content layers to review environmental records alongside property, tax parcel, soil, historical, and other environmental context.
Use multiple data tables, frozen database headers, and the ability to hide “not reported” fields to make large record sets easier to review.
Radius Map data is compatible with LightBox Live tools such as Area of Interest, VEC App, Groundwater Flow, FieldCheck, and Geometry Filter tools to quickly focus on the records most relevant to your review.
