KAYE STREET DRAINAGE IMPROVEMENT
OPTION III
(Cont. )
o The best ultimate solution to resolve drainage
concerns on both sides of Kaye Street.
o If extended drain lines and area drains to the back
yard are considered privately owned, there will be no
need for drainage easements.
o Kaye Street will be a standard residential street
compared to it's existing condition as a substandard
street.
o Less coordination with affected home owners as
compared to other options.
o Construction and engineering time is 6-8 months, once
this project is approved by the City Council.
o The consideration of creation of Drainage and/or
Public IlDprovement District can be time conswning,
delaying completion project by 6-8 lBOnths, in
addition to construction time.
o Creation of such district needs to be carefully
looked at.
o Since there is no outlet from Kaye Street in the
easterly direction, staff has concerns regarding
traffic engineering and public safety, etc.
o This option is more time conswning than any other
option.
o The drainage outfall needs to be carefully studied to
m.ake sure there is no and I or lBinimal impact on any
existing drainage systems.
GENERAL RO'l'ES:
Option III is actually rebuilding Kaye Street.
Such improvement would benefit all affected property owners.
