IN REPLY PLEASEREFER TO FILE: SM'1
This letter is to inform you that Los Angeles County Public Works Consolidated SewerMaintenance District has completed a condition assessment of the City of Walnut's sewersystem.
The enclosed Condition-Assessment Report provides a summary of the maintenance andstructural condition of your sewer mainlines. Please note that a previous report coveringthe balance of your system was transmitted on June 24, 2013. The information containedin both reports should be included in your agency's Sewer System Management Plan asa reference in Chapter 8, System Evaluation and Capacity Assurance Plan.
The segments with critical maintenance issues have been cleaned and, whereappropriate, incorporated into our enhanced maintenance schedule for continuedcleaning and monitoring.

Report By: Eric Liu Report Date: 06/24/2019
INTRODUCTION
As part of the Sewer Condition-Assessment Program, Los Angeles County Public WorksConsolidated Sewer Maintenance District (District) has completed the closed-circuittelevision inspection of 475,490 feet or 100 percent of the City of Walnut’s (City) sewersystem.
The closed-circuit television inspection of the City was completed in twophases (Project Nos. Y0TV0910C and Y0TV1314B2). A copy of theCondition-Assessment Report for Project No. Y0TV0809C can be found in the District'swebsite at http://dpw.lacounty.gov/smd/cctv/city/. Enclosed for your reference is theCondition-Assessment Report for Project No. Y0TV1314B2.
SUMMARY MAINTENANCE REPORT
Our inspection revealed that approximately 83.4 percent of the system televised was freeof significant blockages or restrictions that would impede sewer flows. The remaining16.6 percent of the inspected pipe segments had a Pipeline Assessment and CertificationProgram (PACP) maintenance grade of 3, 4, or 5 as indicated in the Quick MaintenanceRating Table shown below. We have taken corrective actions to address themaintenance issues as noted in the enclosed reports.

INTRODUCTION
The District conducted a condition-assessment of 292,525 feet or 61.5 percent of theCity's entire sewer system as part of Project No. Y0TV1314B2.
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, and InfiltrationList and Map (Enclosure 2)
Quick Structural Rating Report Priority List and Quick Structural Rating PriorityMap (Enclosure 3)
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. Y0TV1314B2 included sewer lines located in the unincorporated County ofLos Angeles and the Cities of Commerce, Glendora, Industry, La Canada-Flintridge, andWalnut. Enclosed for your reference is an overview map of the project area within yourCity (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 82.3 percent of the system televised in yourCity as part of Project No. Y0TV1314B2 was free of significant blockages or restrictionsthat would impede sewer flows. The remaining 17.7 percent of the pipe segments had aPACP maintenance grade of 3, 4, or 5 as indicated in the Quick Maintenance RatingTable shown below. These segments have been incorporated into our periodic cleaningschedule for enhanced maintenance.
A color-coded map showing the quick maintenance rating for each pipe segment isprovided in Enclosure 2.

High-Water Levels
Our inspection revealed that approximately 98.8 percent of the system televised hasadequate capacity. Approximately 1.2 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. When the items have beenidentified to have high-water levels due to sewer line capacity, a Yes is indicated in thecapacity column. These areas should be reviewed by the City for existing and futurecapacity needs.
A map showing the sewer lines with high-water levels is provided in Enclosure 2.
Infiltration
Our inspection revealed that approximately 0.2 percent of the system in your City as partof Project No. Y0TV1314B2 has infiltration within the pipe segments. Infiltration is theingress of groundwater into the sewers through a defect of porous area of the pipe wall.All sewer pipes where infiltration was found are listed on the Infiltration Table inEnclosure 2. This table also provides the proposed corrective action for these impactedsewer segments. If a corrective action is proposed, the work will be programmed in thenext 24 months as part of our ongoing Accumulative Capital Outlay Program.
A map showing the sewer lines with infiltration is provided in Enclosure 2.

STRUCTURAL REPORT
Our inspection revealed that approximately 95.9 percent of the inspected pipe segmentswithin the City were free of severe structural defects. The remaining 4.1 percent of theinspected pipe segments had a PACP structural grade of 4 or 5 as indicated in theQuick Structural Rating Table shown below. These segments have been placed on apriority list based on the severity and the need for action. For items 1 through 57 in theQuick Structural Rating Report Priority List (Enclosure 3), which warrant a correctiveaction, the proposed corrective action will be programmed in the next 24 months as partof the ongoing Accumulative Capital Outlay Program.
A color-coded map showing the Quick Structural Rating for each pipe segment is locatedin Enclosure 3.
