The water system improvements project design services contract, approved by City Council
on April 16, 2013 addressed needs at five locations across the City that consisted of line
replacements /upsizing and new lines to improve system circulation and reduce water
quality issues.
The specific locations targeted in this project were:
• Dooley Street; Silverlake Elementary to Dunn Street
• Dove Loop; Dooley Street to Boyd Drive
• Boyd Drive; Dove Loop to Turner Road
• College Street Crossing of Morehead Branch; Scribner Street to Ball Street
• Winding Creek Addition network Connection to Woodlake Apartments Network
We have identified three additional water line replacement segments that are either
substandard or are experiencing repeated line failures that would make sense to add to
this project due to their proximity to Dooley Street and to Boyd Drive.
Specifically,
• a 2" water line in Redbud Lane in the vicinity of the Dooley Street intersection is
substandard to serve the residential areas as well as the Vineyards Campgrounds

• an existing dead -end 6" line in Cable Creek Court just east of the Dooley Street
waterline segment of the project can be connected with this project to improve water
quality in the cul -de -sac, and
• an additional segment of 8" waterline in Boyd Drive extending south from Turner
Road to Northwest Highway has experienced a number of leaks in the past six
months and needs to be replaced for improved reliability
These three additional segments can be added to the current design contract and
incorporated into the final construction contract.
Construction cost estimate for the three segments are:
6" Line Redbud Lane $ 52,000
6" Line Cable Creek Ct Dead End Line $ 25,000
8" Line Boyd Drive South of Turner Road $ 104,000
Total $ 181,000
Staff recommends approval.
