DISCUSSION

l - Ig -a
V�,
At the Council meeting of November 2, 1999,' the City Council approved an amendment to
Policy 2.1 of the Pavement Management Plan to reflect a 50 -year design life for all new collector
and arterial streets, and affirmed the existing 50 -year design standard for new local streets, and
the existing 20 -year design standard for all reconstructed and resurfaced local, collector and
arterial streets.
As indicated in the presentation to Council on November 2, 1999, the increase is design life is
accomplished through the modification of a street's Traffic Index (a design parameter used in
pavement design). Policy 2.2 of the Pavement Management Plan sets these Traffic Indexes based
on the design life expectancies stated in Policy 2.1.
The 1998 Pavement Management Plan, which contains pavement standards, was adopted by
resolution in April 1998. As a follow -up to the Council action on November 2, 1999, the staff is
requesting that Council adopt a new resolution amending the resolution adopted in 1998 with the
new standards now to be followed.
CONCURRENCES
The City Utilities department is in favor of the new pavement standards.
FISCAL IlKPACT
The fiscal impact of the City's adoption of the new pavement standards was the primary f5cus of
the presentation made to Council on November 2, 1999. Briefly stated; -the increase in design
life for the Collector and Arterial streets will result in an initial construction cost increase of
approximately 15 %, and a lifetime (50 year period) average annual cost decrease of
approximately 30% (including initial cost and periodic maintenance). Details on these costs can
be found in the Council Agenda Report prepared for the November 2, 1999 Council meeting.
