SUBMITTED BY: Kenneth M. Griffin, P.E.
TITLE: Director of Engineering/Public Works
STAFF COMMENTS:
This water line was identified in the Water Distribution System Master Plan as an undersized water line.
Currently, there is a 16" water line north of Bethel Road up to S.H. 121 and there is a 12" water line south of
Airline Drive to Lakeshore Drive. This water line currently exists as an 8" water line. Upgrading this water
line to a 16" water line will complete all deficiencies along Belt Line Road/Denton Tap Road from Lakeshore
to S.H. 121.
Staff recommends approval of the contract with Birkhoff, Hendricks & Conway in an amount not to exceed
$57,240. Staff will be available to answer any questions at the Council meeting.
