A more thorough explanation:

A frontage assessment is a type of municipal tax that is charged to a property owner for local improvements that abut a street or highway, such as sidewalks, pavements, or sewage lines. This means that if a property owner's land is adjacent to a public improvement, they may be required to pay a frontage assessment to help cover the cost of that improvement.

For example, if a city decides to install new sidewalks along a street, the property owners whose land abuts that street may be required to pay a frontage assessment to help cover the cost of the sidewalk installation. This is because those property owners will benefit from the new sidewalks, as they will make the area more accessible and attractive to potential buyers or renters.

Another example of a frontage assessment might be if a city decides to install a new sewer line along a street. The property owners whose land abuts that street may be required to pay a frontage assessment to help cover the cost of the sewer line installation. This is because those property owners will benefit from the new sewer line, as it will make it easier and more convenient for them to connect their properties to the city's sewer system.
