would be necessary to get clearance to view the claim files. A contrary

opinion expressed by James (1965) was that the statistical reliability of

I

the urban depth-damage function does not warrant dividing urban develop-

The actual cash value for single family residential structures averaged

I

$27,700 for a one-story structure with basement; $27,500 for one-story, no

basement; $33,400 for a two or more story with basement; and $34,600 for a

I

two or more story, no basement.

The actual cash value for two to four family residential structures

I

ranged from $36,000 for a one-story structure with basement to $58,900 for

I

a two or more story structure, with no basement. The actual cash value

for all other residential structures averaged $74,100 for a one-story

structure with basement; $40,700 for a one-story, no basement; $145,100

for a two or more story with basement; and $157,500 for a two or more story

no basement.
