6.2.2 Flow Data

No flow data was collected because no streams or creeks were directly affected by the rainfall
event.

6.3 EXTENT OF FLOODING

The flood information collected was obtained principally from Mr. Rippy.

6.3.1 Affected Streams and Local Drainage Areas

There were no streams that were affected by the August 14th event. Mr. Rippy indicated that the
majority of the rain fell due east of West Elk Creek and was collected in the city's storm sewer
system before being discharged into West Elk Creek and eventually into the Colorado River.

Mr. Rippy stated that the majority of the runoff comes from the high point north of town and
travels south down local streets to Main Street, where the storm sewers backed up and flooded
residential properties. General flow paths are illustrated in Figure 6.1-2.

6.3.2 Inundation Limits

The entire city of New Castle was at least partially inundated.

property .

6.4.2 Private Property Damages

The heavy rain triggered a mudslide that flooded several homes and businesses in New Castle.
Total damages were estimated to be approximately $32,000.

6.4.3 Emergency Response, Cleanup, and Repair

Clearing debris from local roads and storm sewers was the majority of work required as a result
of the storm and the flooding. The storm closed u.s. Highway 6 through town as well as several
other local streets. Up to two feet of mud and rocks were left behind after the flooding, and it
took several days to clear the debris. Cleanup efforts amounted to approximately $85,000.
