RECOMMENDATION:
Staff recommends the City Council receive the presentation of the update to the
Pavement Management Program.
BACKGROUND:
In order to be eligible to receive Federal and County highway funds, a municipality is
required to routinely inspect and rate each street segment utilizing a pavement
management program. The City uses the Army Corp of Engineers software,
MicroPaver, to manage the street network. This software is the most widely used in
the country. The City has utilized specialized consultants over the years to review
the defects on each street segment based on Army Corp of Engineers’ standards
and enter the data into the MicroPaver pavement management program. The
program then assigns a pavement condition index (PCI) on a scale of 1 to 100 (with
100 being the best rating).
The program also provides recommendations on the maintenance application of
each street segment. Typically, streets rated 80 to 100 are considered to be in
excellent condition and maintenance is not required. Streets rated 60 to 80 are
recommended to receive a thin layer of slurry seal in order to prolong the pavement
life before a costlier asphalt overlay is required. Streets rated below 60 are
recommended to receive an asphalt overlay. Streets rated below 20 may have to be
completely reconstructed due to large areas of asphalt failure.
On October 13, 2014, the City Council approved a professional services agreement
with Bucknam Infrastructure Group, Inc., to update the Pavement Management
System, for a not-to-exceed cost of $77,030.

Agenda Item Report
DISCUSSION:
Bucknam has successfully completed the update to the Pavement Management
Program without any change orders. There are approximately 121 miles of streets
in the City including alleys. The streets were surveyed by automated digital roadway
imaging with a mobile van unit. While the pavement inspection occurred, the mobile
van also did a GPS survey of the following City assets: street lights, curb markings,
parking meters, and pavement markings. The data has now been linked with the
City's enterprise GIS system to provide mapping in support of managing these City
infrastructures. Such data would make possible creating maps for visualization and
analysis, while also expanding information available for other departments. For
example, deliverables for pavement and curb markings may aid in more mapping
details that could be useful for the Police Department’s traffic and parking
enforcement efforts. Also the information can be provided to the City’s design
consultants as well and save costs on field surveys.
Summary highlights of the Pavement Management Program:
? The overall condition (asphalt and concrete) of the City’s pavement network is
“Fair” with a weighted average PCI of 69.8 without alleys and 67.4 with alleys.
? The weighted average PCI for the Arterial/Collector street network (asphalt
and concrete) is 67.7.
? The weighted average PCI for the Local/Residential street network (asphalt
and concrete) is 71.7.
? About 85% of the entire City streets network is constructed with asphalt.
? The Arterial/Collector asphalt network PCI is 68.4 and is considered to be in
“Fair” condition.
? The Local/Residential asphalt network PCI is 75.2 and is considered to be in
“Good” condition.
PCI RANGE CONDITION
86-100 Very Good
75-85 Good
60-74 Fair (Culver City Network 2015 = 69.8)
41-59 Poor
0-40 Very Poor

Agenda Item Report
The Local/Residential street network represents 53% of the entire roadway system.
In 2008 and 2011, the weighted average PCI of the Local/Residential street network
was 53.2 and 65.4, respectively. Utilizing funds appropriated by the City Council,
Staff has been aggressively resurfacing the asphalt Local/Residential Street network
since 2006. As a result the PCI ratings have significantly improved from a “Poor”
condition to “Good” condition.
The Arterial/Collector street network represents 41% of the entire roadway system.
These streets are typically funded for repaving with annual allotted Federal
Highways funds. Congress has not yet passed a comprehensive reauthorization of
the Transportation Highway Bill. As currently written, the extensions to the current
Highway Bill provide Culver City about $117,000 a year. Repaving one mile of a
four lane arterial street is about $1 million. The City will have to rely on local
General and State Gas Tax funds for repaving arterial streets.
About 15% of the street system consists of concrete paving. Washington Boulevard,
west of Sepulveda Boulevard to the westerly City limits, was constructed in the
1940s and 1950s. Concrete has a much longer service life than asphalt.
Reconstructing these streets entirely is cost prohibitive. Currently, small sections of
the concrete streets are being reconstructed based on available budget. At some
point in the future, new additional funding will have to be budgeted for West
Washington Boulevard and residential concrete streets. Staff is investigating new
technologies such as edge grinding and overlay with asphalt. The City of Santa
Monica recently performed this new technology, and staff will monitor its outcome.
The PCI for the arterial/collector concrete network is 62.3 (Fair). The PCI for the
Local/Residential concrete network is 26.7 (Very Poor) condition.
The PCI for the paved Alley Network is 14.7 and is considered to be in “Very Poor”
condition. The alleys are only maintained by filling potholes. Staff also grades the
unpaved alleys once a year to provide for proper drainage. There is a capital
improvement project for the fine grading of several unpaved alleys. The Alley
Network will require new additional funding in the future as it will come to a point that
the alleys will need to be completely reconstructed.
The report recommends that in order to maintain the current PCI levels of the entire
City road network, approximately $5 million is required for the next 5 years. In order
to increase the PCI to 72, the report recommends an additional $3 million (for a total
of $8 million) for the next 5 years.
After 9 years of resurfacing residential streets, staff will be shifting the rehabilitation
of the City streets to arterial streets for the next several years.
The Final Report of the 2015 Update to the Pavement Management Program is
available at the Public Works Department.
