Section 366.505  D4 Factor (Basement Backups)

 

D4 is a factor that represents the frequency of basement flooding.  D4 is calculated as follows:  (frequency of basement flooding) x (average number of basements affected) = D4.

 

a)         The frequency of basement flooding element will be calculated as follows:

 

0 times per year

=

1.00

1-5 times per year

=

1.01

6-10 times per year

=

1.02

11-15 times per year

=

1.03

16-20 times per year

=

1.04

> 20 times per year

=

1.05

 

b)         The number of basements affected will be calculated as follows using the average number of basements affected by storm events during the previous year:

 

0 basements

=

1.0

1-10 basements

=

1.1

11-25 basements

=

1.2

26-50 basements

=

1.3

51-100 basements

=

1.4

> 100 basements

=

1.5
