Noise Abatement Inventory Request

This information collection request is required by 23 CFR 772.13(f), which requires State Departments of Transportation (DOTs) to maintain an inventory of constructed noise abatement measures and for Federal Highway Administration (FHWA) to collect it via Office of Management and Budget collection requirements. This information is collected electronically every three years via a spreadsheet for the noise abatement inventory. The information to be collected includes location, design characteristics, costs, project specifics and what land uses the abatement measure is protecting from noise. The information is used to create a national inventory that allows FHWA to see trends over time, share the information with the public, use it for research projects, and help State DOTs determine their feasible and reasonable factor in deployment of noise abatement.
