Will a farmer need to provide a "no-rise" certification when building a dairy barn in the floodway?

A "no-rise" certification is essential when construction activities are proposed within a floodway because it ensures that the new development will not increase flood levels in the surrounding area. This requirement is part of managing floodplain development to prevent adverse impacts on flood storage capacity and flow dynamics.

When a farmer intends to build a dairy barn in the floodway, the local floodplain management regulations typically require a no-rise certification to demonstrate that the project will not obstruct the normal flow of floodwaters or elevate flood levels. This is crucial for maintaining safety and reducing flood risks for the farmer and neighboring properties. The certification must be obtained before any construction permit is granted, reinforcing the importance of compliance with floodplain management objectives.

In this case, the other options suggest that no certification is required under various circumstances, but all of those scenarios do not align with the overarching floodplain management requirements aimed at preventing negative impacts from new constructions within flood-prone areas.
