Allegheny County## Overview This is an archive of the [Allegheny County Landslide Portal](https://landslide-portal-alcogis.opendata.arcgis.com/), a web site developed by the Allegheny County Landslide Task Force. --- ## Collection The archive process we used: The Landslide Portal was stored mostly as PDF files, using [single-file HTML](https://www.getsinglefile.com/) archives on pages with many outgoing links, and supplemented by individual links to external resources listed on Landslide Portal pages captured as PDF files. The order of the resources below assumes that the user starts at the home page, and works through the navigation tab left-to-right, browsing each page from top-to-bottom. --- ## Recommended Uses **Disclaimer from the footer of the site:** "For informational purposes and government use only.
