City of Monessen Blight Inventory

Project Background
As part of the Monessen comprehensive planning process, a citywide inventory of blighted properties was conducted in the spring of 2019. This project was conducted in partnership with the City of Monessen, Mackin Engineering, MGR Consulting, and was executed by the Westmoreland County Department of Planning and Development. The purpose of the effort is to support a data-driven, progressive-discipline approach to addressing blight.
The inventory provides a detailed look at property conditions throughout the city, parcel-by-parcel. Properties considered to be blighted are dilapidated, abandoned, and sometimes vacant, and ultimately pose a threat to the health, safety, and welfare of the community.
Blight Inventory

During the course of the project, planners physically inventoried all 5,032 parcels in Monessen. Each property was evaluated based off of the exterior appearance of the property utilizing a three-grade parcel grading system . Parcel grades are visually shown on maps using a three-color system (red=poor, blue=fair, light blue=good). Parcel grades and any additional descriptive notes can be found by clicking on a parcel and viewing the pop-up window.

Tax Delinquent Properties
This map displays varying degrees of tax delinquency as of June 2021. Parcels with a lesser degree of delinquency are displayed in lighter shades of red while parcels with a greater degree of delinquency are displayed in darker shades of red. Parcels considered to be in “poor” condition, are outlined in black.
Types of Tax Delinquency Shown:
- Unsold parcels are those that have gone through tax sale without a buyer purchasing them.
- Judicial Sale parcels are those that are being prepared for judicial tax sale which clears the title of some, but not all, defects.
- Repository parcels are those that are essentially orphaned; meaning no one has purchased at any previous step in the process. They represent the most serious form of tax delinquency.
