The City's water distribution master plan includes this proposed 12 -inch water line to
convey additional water to the northwest portion of the City where peak demand puts a
strain on the existing delivery capabilities. Construction of this 12 -inch line supplements
the recently completed Lake Pointe Subdivision 12 -inch waterline improvements also on
the City's master plan. Council authorized City cost participation in the 12 -inch water line
through Lake Pointe Subdivision in December, 2012.
This proposed 12 -inch waterline connects to the 12 -inch line improvements within Lake
Pointe and completes the 12 -inch line identified in the Masterplan extending from Shady
Brook Drive through Lake Pointe Subdivision to Dove Loop.
