Special assessments encompass costs for which of the following improvements?

Special assessments are a means by which local governments can levy additional charges on property owners to cover the costs of specific improvements that benefit their property. These assessments are typically used for infrastructure projects that enhance the value or utility of the properties within a designated area.

Sidewalks and pavements are common examples of improvements that can be funded through special assessments. They directly benefit the residents and businesses in the area by providing essential infrastructure for pedestrian access and transportation. The installation or repair of sidewalks improves safety and accessibility, making the surrounding properties more attractive and valuable.

Street lights and traffic signals, public parks and recreational areas, and storm drains and sewers can also be funded through various financing mechanisms, but the specific designation of special assessments generally applies more explicitly to projects like sidewalks and pavements due to their direct correlation with enhancing property access and value for local residents. Therefore, choosing sidewalks and pavements as the correct option aligns with the typical usage of special assessments for infrastructure directly benefiting those properties.
