TO : THE HONORABLE CITY COUNCIL .C<<,
FROM : DIRK LOVETT, ASSISTANT CITY ENGINEER f
PREPARED BY TONY COOPER, PROJECT MANAGER
DATE : NOVEMBER 13, 1996 (CITY COUNCIL MEETING OF
NOVEMBER 20 , 1996 )
SUBJECT : SLURRY SEAL REPAIRS
BACKGROUND
At the City Council Meeting of November 6 , 1996 staff was asked to
reevaluate the condition of 3 streets. Buttercreek Rd. ,
Alderbrook Street and Monroe Avenue.
DISCUSSION
On November 11th these streets were again evaluated by the
Engineering Department . Each of these streets underwent repair
work subsequent to the initial slurry application. Buttercreek
and Alderbrook sustained damage due to vehicles which ignored
posted signs and bypassed barricades . Monroe was reslurried in
specific areas due to extreme surface texture irregularities .
On these and all other streets that were repaired, subsequent to
the initial application, the contractor undertook reasonable
measures to repair the tire marks and texture irregularities per
the specifications .
The purpose of the slurry seal is to protect the underlying
surface from damage due to the atmospheric elements thus extending
the life of the pavement . According to the standard
specifications, the contractor is required to repair or reseal all
areas of the street which have not been sealed properly or
completely. It should be noted that although repair patches are
immediately noticeable due to the darker color they will quickly
fade to resemble the rest of the streets .
Where the rough texture was reslurried, rideability has been
noticeably improved, where tire marks adversely impacted the
integrity of the slurry the contractor applied a second coat of
slurry to protect the asphalt . Color and texture irregularities
will become less apparent over time.

CONCLUSION
The slurry seal application and repair work complies with the
intent of the specifications .

Staff recommends that the City Council take the action as outlined
in the November, 6, 1996 agenda report (attached) .

Agenda Report
City of Moorpark
To: The Honorable City Council
From: Kenneth C. Gilbert, Director of Public Works
Dirk Lovett, Assistant City Engineer
Prepared By: Anthony Cooper, Civil Engineer
Date: October 28, 1996 (Council Meeting November 6, 1996)
Subject: Notice of Completion for 1996 Slurry Seal Project
BACKGROUND
On November 15, 1995, the City Council awarded a contract to Valley Slurry Seal for slurry
sealing various streets throughout the City. Slurry sealing protects the existing pavement
from the effects of the sun and elements, thus extending the life of the pavement.
DISCUSSION
A. Slurry Application
The City Council awarded a contract for this work in November 1995. The slurry
application began on April 1, 1996. Final repairs were completed on October 9, 1996.
B. Additional Work
In May of 1996, the City Council approved an increase to the cost of the project. to
cover an anticipated increase in the amount of materials required to apply slurry seal to
all of the streets specified. The initial bid documents quoted estimated quantities for
certain bid items which were too low. This error was caused by the use of aerial photos
in lieu of actual field measurements to estimate those quantities. Again, the scope of
work did not change, just the estimated quantities of material required to perform that
work. That City Council action included the approval of an increase to the budget
amount for this project from $400,000 to $500,000.
C. Change Orders
Two Change Orders were issued. The first change order [$3,110.001 added a number
of industrial streets to the list of streets specified. The second change order [Credit
amount of ($784.00)] was a credit amount for City costs for premium overtime pay for
inspection.

D. Slurry Rep: Work
After application of the slurry some of the streets were observed to have some rippling
and rough texture. City Engineering sent the contractor a letter on May 22, 1996
regarding this and providing a final punch list for repairs. The contractor returned in
October and applied a thin course of slurry to those areas of the streets deemed
unacceptable. Patching due to tire damage was also done as part of the repair. The
repair work has provided a smoother driving surface to these localized areas.
E. Final Inspection and Acceptance
The City Engineer has completed a final inspection of the project and has found the
work to be acceptable. At this time it would be appropriate for the City Council to
accept the project as completed, direct the City Clerk to file a Notice of Completion and
authorize release of the retention.
