DEL NORTE (CONTINUED)

Hydrology - The hydrology was developed by CDM using a log
Pearson Type III distribution for the gage at Del Norte.

Hydraulics - 1.0 mile of the Rio Grande River was studied in
detail for the 10, 50, 100 and 500 year floods. A 1.0
foot floodway was also calculated.

Profiles - 0.6 miles of the Rio Grande River was drafted.

Floodplain Maps - 0.6 miles of the Rio Grande River was drafted
showing the 1.0 foot floodway and the 100 and 500 year
flood boundaries in the corporate limits (see USGS maps):

MONTE VISTA:

Mapping - 7.3 miles of the Rio Grande River is mapped showing all
of Monte Vista. The map is a topographic map with 2'
contours (see attached USGS maps).

Field Recon.- The field reconnaisance was performed by CDM for
the floodplain and bridges along the Rio Grande River.

Hydrology - The hydrology was developed by CDM using a log
Pearson Type III distribution for the gage at Del Norte
and transferring this data to Monte Vista using methods
from TMl.

Hydraulics - 7.3 miles along the Rio Grande River was studied in
detail for the 10, 50, 100 and 500 year floods. No floodway
was computed.

Profiles - 4.9 miles of the Rio Grande River at Monte Vista was drafted.

Floodplain Maps - 1.7 miles of the 100 and 500 year flood boundaries
were drafted inside the corporate limits (see USGS maps).
