BACKGROUND
The Public Works Services Department (“PWSD”) is responsible for the maintenance and
repair of approximately 147 miles of roadway within the City. The 2017 Pavement
Management Program Update assessed the condition of all City streets and assigned a
numerical index between 0 and 100 which is used to indicate the general condition of a
pavement. The Annual Slurry Seal Maintenance Program assists in extending the life
expectancy of streets and improves the overall appearance and safety of City streets.
This program provides surface maintenance of all City streets and divides the City up into
eight zones, with one zone being addressed each year as part of an eight-year cycle.
Updates to the plan are conducted regularly to ensure that the program is effective and
to identify street segments with unusual wear and tear.

DISCUSSION
On January 21, 2020, the City Council approved a contract with Doug Martin Contracting
Co., Inc. for the Fiscal Year 2019-20 Annual Slurry Seal Project. The work performed
encompassed approximately 12.3 miles of residential and arterial streets and included
crack sealing, the application of an emulsified asphalt and sand coating commonly
referred to as slurry, and re-striping of street centerlines, stop bars, and pavement
markers. This process protects the asphalt pavement surface from weather, restores skid
resistance, and provides an aesthetic uplift to the street and neighborhood.
During the course of work, staff evaluated the quality of the slurry sealing and made
adjustments with the contractor to ensure the best possible outcome. There was an
addition in the amount of Type II slurry seal application due to some streets needing a
thicker application of slurry. Below is a description of the contract change order.
CCO# Description Amount
1. Additional (37 TONS) of Type II Slurry $7,425.90
Total: $7,425.90
The terms and conditions of this contract have been complied with and the work has been
performed to the satisfaction of the Project Manager. Doug Martin Contracting Co., Inc.
completed the work as defined in the project plans and specifications in an efficient and
timely manner.
FISCAL IMPACT
Funds in the amount of $600,000 have been budgeted in the Fiscal Year 2019-20 Capital
Improvement Program for the Annual Slurry Seal Program. The total cost for this Project
is $494,327.90. This amount reflects the original contract amount of $486,902 plus
quantity changes totaling $7,425.90, or 1.5% more than the original contract amount. A
10% construction contingency was approved for the Project at the January 21, 2020,
Council Meeting. The remaining funds from the Slurry Seal project will be used for
sidewalk, curb, and gutter repair in this same area.
