danger of injury or drowning. High velocity flows through
Breckenridge could erode stream banks, thereby threatening the
foundations of buildings and bridge abutments, and creating
hazards to curious spectators. Cold nights during the early
part of the runoff season cause streets, subject to shallow
flooding, to become glazed ice. Sewage, garbage and other
organic materials carried or deposited by floodwater create
hazards to health. Serious problems could result in providing
emergency medical, fire and law enforcement services to areas
isolated by floods.

FLOODED AREAS AND FLOOD DAV~GES

The areas along the Blue River through the town of Brecken-
ridge that would be inundated by the Intermediate Regional and
the Standard Project Floods are shown on Plates 3 through qt.
Plate 2 is an index map showing the relative location of the
plates within the town of Breckenridge.

Flooding along the Blue River generally parallels the river
in a wide band occupying low lying areas and adjacent flat
lands. The Intermediate Regional Flood for the most part is_con-
fined to the present Blue River channel." ~ocalized flo,~~~,~'[l: ''71.0''
will occur, however, at four crossings. The crossing at the
Broken Lance Road (upstream) will barely pass the Intermediate
Regional Flood, however, the Broken Lance Road (downstream)
crossing will not pass the flood and localized flooding occurs.
Flood waters return to the Blue River channel after the Broken
Lance (downstream) crossing, stay in the channel and are passed
through each succeeding cr~ssing until the Watson Street
crossing is reached. At this point, the capacity of the single
culvert is not enough to pass the entire flood. Localized
flooding again occurs with flood waters spreading to Colorado
State Highway No.9. At this crossing, several residences and
commercial buildings are inundated by the flood waters. The
flows return to the Blue River channel immediately downstream
of the crossing and the flood stays in the channel for the rest
of the reach through the town. Localized flooding will occur
