Credits and data sources

Yard Waste Dropoff is built only from sources we're allowed to use. We do not use Google Maps, Google Places, Yelp, Facebook, ChipDrop or any source whose terms forbid it.

Facility data

Government sources

Most listings summarize facts (address, hours, fees, rules) published by state, county and city agencies. Each listing links to its source page and shows when we last checked it. The official page — or the site itself — is always the final word.

OpenStreetMap

Some listings and all base map data come from OpenStreetMap, © OpenStreetMap contributors, available under the Open Database License (ODbL) 1.0. Share-alike applies to the OSM-derived portion of our database. OSM-derived listings are labelled “Source: OpenStreetMap” and link to the original OSM object.

GeoNames

Approximate map pins (ZIP, city or county center), county names and ZIP/city search use GeoNames postal-code data, licensed CC BY 4.0, via the zipcodes-us npm package.

Map

Maps use MapLibre GL JS (BSD-3-Clause) with free vector tiles from OpenFreeMap, using the OpenMapTiles schema and OpenStreetMap data. No API keys or paid map services.

Images

This site currently uses no photographs. Any future image will be a public-domain US government work or a Creative Commons–licensed image, credited here and next to the image.
