"F" Street Widening, Fourth Avenue to
Church Avenue
SUBMITTED BY Director of Public Works/City Engineer /,~% r
ITEM EXPLANATION (4/5TH'S VOTE REQUIRED YES NO x
The City's typical design standard for a street structural pavement
section is to place aggregate base material under the pavement, but
not under the curb and gutter. In instances where unsuitable and expan-
sive soil conditions are encountered in the field, Engineering staff has
incorporated special designs to cope with potential problems.
During the excavation to subgrade for the improvement of "F" Street,
it has been discovered that the existing soil conditions are excessively
moist and that the native soil is expansive. This is an unsuitable
street construction condition. As a result, Engineering staff is
recommending that aggregate base material be placed beneath the curb and
gutter. The purpose of placing the base material under the curb and
gutter is to eliminate the possibility of extensive cracking and
displacement of the new curb caused by the expansiveness of the native
soil.
The additional base material needed

in the contract cost of $2,275.00.
