A standard project flood is a flood that would result from a storm that is considered reasonably characteristic of the region in which the drainage area is located, giving consideration to the runoff characteristics of the drainage area and excluding rare combinations of meteorologic and hydrologic conditions. Such a flood provides a reasonable upper limit to be considered in designing flood control improvements and floodplain limits.
“Freeway.”
A freeway is any dedicated or deeded public right-of-way to which the owners of abutting lands have no right or easement of access to or from their abutting lands. In addition, freeways shall include those rights-of-way designated by official action as freeways by the California State Highway Commission or the City Council.
