(I) Soil Group maps are available at the :officesof the Department of Public Works.
(2)Where actual conditions deviate significantly from the tabufated impervious-
ness values of 80% or 90010, the values given for coefficient C, may be revised
by multiplying 80% or 90% by the ratio of actual imperviousness to the
tabulat~d imperviousness. However, in no case shall the final coefficient
be ,less than 0.50. For example: Consider commercial property on D soi I.-group.
Actual imperviousness
= 50%
Tabulated imperviousness = 80<'10
Revised C = 50 x 0.85 = 0.53
