Flood zones are designated by the 100-year and 500-year flood boundaries. The prior indicates a greater risk for flooding. Sites located within a zone compared to sites located on a zone boundary vary for risk. Review the accompanying map and the content provided at the Legend link in the introduction to identify which sites are located in which zones and how that relates to flood risk. Learn more about each neighborhood by clicking on its name on the city map located at the Map link. What does each zone designation mean for each neighborhood?

 The correct answer is:

1: All of Downtown is within Zone C and is relatively safe from flooding.

2: The HazardCity railroad on the south side of the river lies in Zone B and is only in danger of floods larger than the 100-year flood event.

Explanation:

Floods are caused by excess water, invading areas that are normally dry.

This phenomenon plays an important role in the regulation of water systems, for this reason, when these systems are modified or areas susceptible to flooding are affected, affectations can be generated.

The settlement of homes in areas of Ronda and, of environmental management and preservation of water bodies, increases the vulnerability to flood events, since such homes can be affected by the increase in the level of water bodies , in the same way they can affect the margins of the rivers and creeks by the realization of uncontrolled excavations for the foundation of the houses and by the constant traffic of all types of vehicles.
