CONSOLIDATED SEWER MAINTENANCE DISTRICTCONDITION ASSESSMENT PROGRAM REPORTUNINCORPORATED COUNTY
This memo is to inform you that the Los Angeles County Public Works ConsolidatedSewer Maintenance District (District) has completed a Sewer Condition AssessmentProgram of a portion of the unincorporated County's sewer system maintained by theDistrict's East Yard.
The enclosed Condition Assessment Report provides details regarding the maintenanceand structural condition of your City's sewer mainlines. This information should beincluded in the District's Sewer System Management Plan as a reference in Chapter 8,System Evaluation and Capacity Assurance Plan. The segments with criticalmaintenance issues have been cleaned and, where appropriate, incorporated into ourenhanced maintenance cleaning schedule for continued monitoring. In addition, thesegments with severe structural defects have either been repaired or will be scheduledfor repair or replacement as part of the ongoing Accumulative Capital Outlay Project.

INTRODUCTION
As part of the Sewer Condition Assessment Program, the Los Angeles County PublicWorks Consolidated Sewer Maintenance District (District) has completed the conditionassessment of 496,819 feet or 14.0 percent of the unincorporated County’s sewer systemmaintained by the District’s East Yard.
The enclosed Condition Assessment Report outlines the structural and maintenanceratings of your system based on the PACP's (Version 6.0.1) rating methodology.Included in the report are the following:
Project Overview Map (Enclosure 1)
Quick Maintenance Rating Map, High Water Levels List and Map (Enclosure 2)
Quick Structural Rating Report Priority List and Quick Structural Rating PriorityMap (Enclosure 3)
The District has now completed the condition assessment of 1,335,879 feet of theunincorporated County’s sewer system maintained by the District’s East Yard. PreviousCondition Assessment Reports dated April 6, 2009, October 8, 2009, June 20, 2013, May28, 2009, January 5, 2011, May 20, 2011, November 18, 2016, and November 28, 2016have been provided to you. A copy of the reports can also be found in the District’swebsite at http://dpw.lacounty.gov/smd/cctv/city/.
The Sewer Condition Assessment Program utilizes the PACP Quick Rating methodologyto rank the structural and maintenance condition of your system based on industrystandards.

PROJECT AREA AND DESCRIPTION
Project No. Y0TV10111A included sewer lines located in the unincorporated Los AngelesCounty and the cities of La Habra Heights, Irwindale, Glendora, Diamond Bar, andCommerce. Enclosed for your reference is an overview map of the project area within theunincorporated County (Enclosure 1).
DEFECT GRADE DESCRIPTION
The Quick Rating indicates the number of occurrences for the highest severity grade foreach pipe segment for either maintenance or structural defects. A grade of 1 indicatesthat a pipe segment is in excellent condition with minor defects while a grade of5 indicates that a pipe segment may require immediate attention. A legend of the fivepossible defect grades is as follows:
Grade Defect Grade Description
1: MINOR
2: MINOR TO MODERATE
3: MODERATE
4: SIGNIFICANT
5: MOST SIGNIFICANT
MAINTENANCE REPORT
Our inspection revealed that approximately 83.7 percent of the system televised inunincorporated County as part of Project No. Y0TV1011A was free of significantblockages or restrictions that would impede sewer flows. However, the remaining 16.3percent of the pipe segments within the unincorporated County had a PACP maintenancegrade of 3, 4, or 5 as indicated in the Quick Maintenance Rating Table shown below.These segments have been incorporated into our routine cleaning schedule withcorrective action taken.
A color-coded map showing the quick maintenance rating for each pipe segment isprovided in Enclosure 2.

TOTAL 498,902 100.0 2215
High Water Levels
Our inspection revealed that approximately 99.6 percent of the system televised hasadequate capacity. Approximately 0.4 percent of the segments inspected exhibited visualsigns associated with high water levels. The capacity of the sewer pipe can bedetermined by analyzing several PACP codes, including Water Level, Water Mark, andmiscellaneous remarks, which indicate the camera was underwater or there were sags inthe line. A sewer pipe is considered at capacity when 50 percent of the diameter of thesewer pipe is full of water. However, there are conditions in which the Water Level orWater Mark has reached 50 percent or greater due to heavy flows in adjoining pipes, atemporary stoppage caused by debris in the sewer lines, or a sag in the line.Therefore, additional review of these pipe segments was conducted to determine if anycapacity issues exist.
All sewer pipes where the Water Level, Water Mark, and miscellaneous remarks ofcamera underwater or sags in the line are at or above 50 percent capacity have beenlisted and analyzed on the High Water Level Table in Enclosure 2. The nature of thesehigh water level conditions is also summarized on this table.
A map showing the sewer lines with high water levels is provided in Enclosure 2.
Infiltration
Our inspection revealed that infiltration was not detected in any pipe segment in theCounty’s sewers.
STRUCTURAL REPORT
Our inspection revealed that approximately 97.5 percent of the inspected pipe segmentswithin the unincorporated County were free of severe structural defects. However, theremaining 2.5 percent of the inspected pipe segments had a PACP structural grade of 4or 5 as indicated in the Quick Structural Rating Table shown below. These segmentshave been placed on a priority list based on the severity and the need for action. Foritems 1 through 58 in the Quick Structural Rating Report Priority List (Enclosure 3), which

warrant a corrective action, the proposed corrective action will be programmed in the next24 months as part of the ongoing Accumulative Capital Outlay Program.
A color-coded map showing the Quick Structural Rating for each pipe segment is locatedin Enclosure 3.
