USE OF AIR PHOTOS IN CAPE PERFORMANCE

A, Introduction: This guide is for use by CAPE reviewers. It
shows how to use air photos along with the community's flood
insurance maps and study as a means of familiarization with the
area of interest, problem identification and documentation of the
CAPE proceedings.

B. Preparing for the CAPE Visit: Have available the flood
insurance study and have open the community's flodd insurance
maps. Refer to them frequently while reviewing the air photos.
Start, using only one photo. Scan it primarily with the naked
eye, but use a low-power magnifier occasionally, if needed. View
the photo systematically, moving from general to more specific
features. Take several mintues to become familiar with the area
using the following technique:

l. Scan the area as a whole, noting:

a. variations in topography (flat, hilly, mountainous,
etc. )
b. gross land use patterns
c. major drainages
d. size of the community
e. boundaries of the community

2. Continue scanning, but narrow your field of view to those
areas you will be visiting, noting:

a. community land use pattern
b. amount and location of developable land (in and out
of floodplain)
c. ongoing large-scale development
d. indications of future development (clearing and
grading, road extensions, etc,)
e. location of central business district relative to
floodplain/floodway
f. location of major drainages and tributaries
g, extent of floodplain and floodway areas
h. potential changes in floodplain or floodway
bounderies
i. existence and location of additional potential
hazards (erosion and sedimentation, dams, alluvial
fans, wastewater facilities, etc.)

3. Continue scanning, but narrow your field of view to the
community's flood hazard areas, noting:

a. loss exposure--

(i) extent of occupancy (floodplain and
floodway l
