How far back from the pond must Amelia build her garage?

The requirement for how far Amelia must build her garage from the pond is determined by environmental regulations aimed at protecting water bodies. In many jurisdictions, including Maine, building setbacks are established to minimize impacts on water quality and habitat by preventing runoff pollutants and preserving natural vegetation.

In this case, the correct distance she must maintain is 250 feet from the high water line. This distance is intended to create a buffer zone that helps protect the aquatic ecosystem and reduces the risk of erosion, sedimentation, and other impacts that could degrade the pond's health.

Building a garage too close to the water body could disrupt important habitats and increase the risk of contaminants entering the water. Therefore, maintaining a significant distance from the high water line is essential for environmental conservation and compliance with local land use regulations.

The other options suggest either a closer distance or refer to the low water line, which might not offer the same level of environmental protection and is not commonly the standard setback requirement. The focus on the high water line specifically aligns with established protective measures.
