Street Quality Evaluation 

How does Lansing evaluate its streets?

The City of Lansing uses a 1 to 10 scale for visually rating the surface condition of a pavement, with 1 being a pavement in a failed condition and 10 being a pavement in excellent condition. Guidelines for rating the pavement surface have been developed by the Michigan Transportation Asset Management Council.

Why Does the City Use this Scale?

Most pavements will deteriorate through various phases. The rate at which pavement deteriorates from excellent condition (10) to very poor condition (1) depends largely on its environment, traffic leading conditions, original construction quality and interim maintenance procedures. The City of Lansing has recognized the benefits of performing regular pavement grading to know the existing conditions and to find the best places to fix the streets. The grading scale is one aspect of a larger  program not only for pavements but for all infrastructure in the City.

Also called the PASER rating scale, it can generally be translated into maintenance categories as follows:

Shown in the table to the right is the complete street rating of all of Lansing's streets. As you can see, more than 62 percent of the street network has a poor or worse grade.
