What principle states that those benefiting from projects should pay for it?

The principle that those benefiting from projects should pay for them aligns most closely with the concept of intergenerational equity. This principle emphasizes fairness across generations, ensuring that the costs of services and developments are borne by those who will benefit from them, rather than imposing these costs on future generations. In practice, this means that funding for projects should be sourced from current beneficiaries, thereby promoting sustainable financial practices over time.

In contrast, other options deal with different aspects of funding and financing. For example, "pay as you go" refers to a funding approach that emphasizes using existing revenues rather than going into debt, while "impact fees" specifically relate to charges imposed on developers to cover the cost of public infrastructure necessitated by their development. The "Brownfield Economic Development Initiative" focuses on redeveloping contaminated properties and may include various funding strategies but does not directly address the principle of beneficiaries paying for the projects.

The concept of intergenerational equity is critical in public finance as it supports the idea that those enjoying the benefits should also shoulder the expenses, fostering a fair and balanced approach to budgeting and resource allocation.
