What This Source Covers
Polygon layer marking mapped landslide-prone areas with acreage, square-mile, and code fields.
This is a static hazard-area overlay used to show where terrain risk exists even when no incident point is present.
Why Someone Would Open This Page
This source appears on 114 of the 219 mapped place pages in the Allegheny County section, including 29 borough and township pages and 85 Pittsburgh neighborhood pages. That gives a quick sense of how broadly the layer is used across the county.
The example below is here to make the source concrete. Instead of talking about the layer in the abstract, the page shows what it actually looks like on the map.
Example Map
This page uses 011 – Landslide Prone in Hazelwood as the example area. Dense sources use a full selected place; lighter sources use the full sample area.
