Impact Check is THE ONLY NATIONAL database of public improvement projects and THE ONLY NATIONAL database of Locational Obsolescence (off-site conditions that may affect a property's value or desirability) that show impacts and potential impacts to a property, including potential future direct and indirect impacts from public improvement projects such as future new road construction, road widenings/extensions, and existing off-site property conditions such as nearby wastewater treatment plants, gas pipelines, sex offenders, and more.
Just like no one buys a used car without a history report, no one should buy real estate without a Property Impact Report.
Infrastructure & Energy
Crude oil, natural gas, hazardous liquid, and gathering pipelines; high-voltage electric transmission lines; and power plant locations (nuclear, fossil fuel, and renewable) are among the most consequential off-site conditions for nearby properties.
- Crude Oil Pipelines
- Natural Gas Transmission Pipelines
- Hazardous Liquid Pipelines
- Gas Gathering Pipelines
- Electric Transmission Lines (High Voltage)
- Nuclear Power Plants
- Other Power Plants
Transportation
Planned and active roadway projects, railroad lines, and airports are tracked nationally. New road construction, road widenings, and extensions can result in direct property takings (eminent domain) or indirect value impacts from traffic, noise, and access changes.
- Planned Road Construction
- Road Widenings & Extensions
- Railroads & Rail Crossings
- Airports (commercial and general aviation)
Environment & Public Safety
Environmental hazard sites, landfills, and wastewater treatment facilities are permanent off-site conditions affecting desirability and marketability. Sex offender proximity data is also included at the property level.
- Wastewater Treatment Plants
- Landfills & Transfer Stations
- EPA Superfund Sites
- Sex Offenders (registered, within radius)
