approximately 45 percent of the City of Bradbury's sewer system.
The enclosed report outlines the structural and maintenance ratings of your system
based on the Pipeline Assessment and Certification Program's rating methodology.
Included in the report are the following:

The Condition Assessment Report will provide you with details regarding the
maintenance and structural condition of your City's sewer mainlines. This information
can be included in your agency's Sewer System Management Plan as a reference in
Chapter 8.0, System Evaluation and Capacity Assurance Plan. The segments with
critical maintenance issues have been cleaned and, in some instances, have been
incorporated into our routine cleaning schedule for continued monitoring. In addition,
the segments with severe structural defects have either been repaired or will be
scheduled for repair as part of the ongoing Accumulative Capital Outlay Project.
If you have any questions regarding this report or the Condition Assessment Program,
please contact Mr. Robert Swartz at (626) 300-3367, Monday through Friday, 8 am. to

INTRODUCTION
As part of the Sewer Condition Assessment Program, the County of Los Angeles
Department of Public Works Consolidated Sewer Maintenance District has completed
the closed-circuit television (CCTV) inspection of 4,843 feet or 45 percent of the City of
Bradbury's sewer system.
The Sewer Condition Assessment Program utilizes the Pipeline Assessment and
Certification Program (PACP) Quick Rating methodology to rank the structural and
maintenance condition of your system based on industry standards.
PROJECT AREA AND DESCRIPTION
Project YOTV0506D included sewer lines located in both the Unincorporated County of
in the Cities of Glendora,
Los Angeles area and
Bradbury,
Duarte,
La Canada Flintridge, and San Dimas. Enclosed for your reference is an overview map
of the project area within your City (Enclosure 1).
DEFECT GRADE DESCRIPTION
The Quick Rating indicates the number of occurrences for the highest severity grade for
each pipe segment for either maintenance or structural defects. A grade of 1 indicates
that a pipe segment is in excellent condition with minor defects, while a grade of 5
indicates that a pipe segment may require immediate attention. A detailed breakdown
of the five possible defect grades is as follows:
Grade
Description
Estimate time to Failure
1:
EXCELLENT: Minor Defects.
Unlikely in the foreseeable future
2:
GOOD: Defects that have not begun to deteriorate.
20 years or more
3.
FAIR:
Moderate defects that will continue to
deteriorate.
10 to 20 years
4:
POOR: Severe defects that will become grade 5
defects within the foreseeable future.
5 to 10 years
5:
IMMEDIATE ATTENTION:
i mmediate attention.
Has failed or will likely fail within the
next 5 years

MAINTENANCE REPORT
Our inspection revealed that approximately 83.6 percent of the system televised was
free of blockages or restrictions that would impede sewer flows. However, the
remaining 16.4 percent of the inspected pipe segments within the City of Bradbury area
had a PACP maintenance grade of 4 as indicated in the Quick Maintenance Rating
Table shown below. These segments have been incorporated into our routine cleaning
schedule with corrective action taken as noted on the Quick Maintenance Rating Report
Priority List (Enclosure 2). Also included is a color-coded map showing the quick
maintenance rating for each pipe segment.

STRUCTURAL REPORT
Our inspection revealed that approximately 92.8 percent of the inspected pipe segments
within the City of Bradbury were free of severe structural defects. However, the
remaining 7.2 percent of the inspected pipe segments had a PACP structural grade of 4
as indicated in the Quick Structural Rating Table shown below. These segments have
been placed on a priority list based on the severity and the need for action. Item 1 in
the Quick Structural Rating Report Priority List (Enclosure 3) includes defects that do
not impact the structural integrity of the pipe. At this time, no action is recommended. A
color-coded map showing the Quick Structural Rating for each pipe segment is located
in Enclosure 3. A copy of the actual inspection reports for this segment is included in
Enclosure 4.
