Final answer:
The possibility of building a nonresidential building on fill in a floodway is complex, involving strict regulations, safety concerns, environmental impacts, and community guidelines. All aspects require thorough assessment before construction to determine the feasibility and to mitigate any potential negative consequences.
Step-by-step explanation:
Building on Floodway Fill
The construction of a new nonresidential building on fill in a floodway is highly regulated. Floodways are areas reserved to channel flood waters and are essential for managing flood risk. Before any development is done in a floodway, an analysis must be conducted to ensure it will not increase flood heights. The base flood elevation (BFE) and existing floodplain management ordinances have to be reviewed. Moreover, extra considerations might be needed to protect the building from flood damage and to ensure the safety of future occupants.
Assessment of flood risks is a critical component when considering building on a floodway. As flood stage is reached, it overflows and affects surrounding developments. Considering the possibility of another flood with a similar discharge to previous events (like the one from 9/23/2009) is essential for future planning. While floodplains offer attractive development locations, the potential for flooding necessitates extra caution.
Developments within flood-prone areas have the potential to affect groundwater levels, private wells, and the overall ecosystem. For instance, a housing development drawing water from multiple groundwater wells could lower the water table, affecting nearby private wells and altering the natural flow of the river, which is critical for maintaining local ecosystems.
Overall, the challenges posed by building on floodway fill should be carefully evaluated with respect to environmental impacts, safety regulations, and community planning guidelines.
