Final answer:
New sidewalks on a single street are typically paid for by local government budgets, special improvement districts, or direct assessments to benefiting property owners.
Step-by-step explanation:
New sidewalks installed on only one particular street will likely be funded by local government budgets, special improvement districts, or through a direct assessment to the property owners who benefit from the sidewalk. Funding for such neighborhood improvements often comes from the city's capital improvement program.
Which allocates money for infrastructure projects. Additionally, if there is a substantial benefit to the residents or businesses on that street, they might bear some of the costs through a special assessment that would be added to their property tax bills.
In some cases, grants or state funding could also be available, particularly if the sidewalk serves a broader public purpose, such as providing safer routes to schools or improving pedestrian access for underserved communities.
