Dear Ms. Vu:

CONSOLIDATED SEWER MAINTENANCE DISTRICTCONDITION ASSESSMENT PROGRAM REPORTPROJECT No. YOTV0910C

This letter is to inform you that as part of the Sewer Condition Assessment Program, theCounty of Los Angeles Department of Pubic Works Consolidated Sewer MaintenanceDistrict has completed the closed-circuit television inspection of '111,378 feet or53.4 percent of the City of Bell Gardens' sewer system.

The enclosed report outlines the structural and maintenance ratings of your systembased on the Pipeline Assessment and Certification Program's (PACP Version 6.0.1)rating methodology. Included in the report are the following:

• Condition Assessment Report

• Project Overview Map (Enclosure 1)

• Quick Maintenance Rating Report Priority List and Quick Maintenance RatingMap (Enclosure 2)

• High Water Levels List and Map (Enclosure 2)

• Quick Structural Rating Report Priority List and Quick Structural Rating Map(Enclosure 3)

• Infrastructure Inspection Reports for Grades 4 and 5 (Enclosure 4)

Ms. Chau VuApril 25, 2012Page 2

The Condition Assessment Report provides details regarding the maintenance andstructural condition of your City's sewer mainlines. This information should beincluded in your agency's Sewer System Management Plan as a reference inChapter 8.0 System Evaluation and Capacity Assurance Plan. The segments withcritical maintenance issues have been cleaned and, where appropriate, incorporatedinto our enhanced maintenance schedule for continued monitoring. In addition, thesegments with severe structural defects have either been repaired or will be scheduledfor 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, Sewer Maintenance Division, at (626) 300-3367,Monday through Friday, 8 a.m. to 4 p.m., or [email protected].

CONSOLIDATED SEWER MAINTENANCE DISTRICT PROJECT NAME: Y0TV0910C PROJECT MGR: Hanna Kebede PROJECT DATE: 01/27/2011 CONTACT NO: (626) 300-4686 SUP. DISTRICT(s): 1 MAP PAGE(S): 1864, 1917 & 1918 Report By: Hanna Kebede Report Date: 04/17/2012 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 111,378 feet or 53.4 percent of the City of Bell Gardens’ sewer system. The Sewer Condition Assessment Program utilizes the Pipeline Assessment and Certification Program (PACP Version 6.0.1) Quick Rating methodology to rank the structural and maintenance condition of your system based on industry standards. PROJECT AREA AND DESCRIPTION Project Y0TV0910C included sewer lines located in the Unincorporated County of Los Angeles area and in the Cities of Bell Gardens, Industry, Diamond Bar, La Canada Flintridge, and Walnut. 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 Defect Grade Description 1: MINOR

2: MINOR TO MODERATE

3: MODERATE

4: SIGNIFICANT

5: MOST SIGNIFICANT

MAINTENANCE REPORT Our inspection revealed that approximately 86.3 percent of the system televised was free of blockages or restrictions that would impede sewer flows. However, the remaining 13.7 percent of the inspected pipe segments within the City of Bell Gardens area had a PACP maintenance grade 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 with corrective action taken as noted on the Quick Maintenance Rating Report Priority List (Enclosure 2). In addition, a color-coded map showing the quick maintenance rating for each pipe segment is provided in Enclosure 2.

TOTAL 111,378 100.0 459 Lateral Notices Also included on the Quick Maintenance Rating Report Priority List are deficiencies discovered inside lateral connections to the mainline. The District does not maintain lateral lines; it is the responsibility of the property owner to maintain their respective lateral lines to facilitate the flow of wastewater from their property to the mainline. A letter will be sent to the lateral owner notifying them of the maintenance issues discovered in their lateral. A sample lateral notice letter is provided in Enclosure 2 for your reference. High Water Levels Our inspection revealed that approximately 99.97 percent of the system televised has adequate capacity. However, the remaining 0.03 percent of the inspected segments included deficiencies associated with high water levels. Capacity of the sewer pipe can be determined by analyzing several PACP codes, including Water Level, Water Mark, and miscellaneous remarks, which have indicated camera underwater or sags in the line. A sewer pipe can be considered at capacity when 50% of the diameter of sewer pipe is full of water. However, there are particular conditions in which the water level or water mark has reached 50% or greater due to heavy flows in adjoining pipes, a

temporary stoppage due to debris in the sewer lines, or a sag in the line. Therefore, additional review of all pipe segments with such high water level concerns was conducted to determine capacity issues, if any. All sewer pipes where Water Level, Water Mark, and miscellaneous remarks of camera underwater or sags in the line are at or above 50% capacity, have been outlined and analyzed on the High Water Level table in Enclosure 2. The nature of these high 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 your City’s system. STRUCTURAL REPORT Our inspection revealed that approximately 94.8 percent of the inspected pipe segments within the City of Bell Gardens were free of severe structural defects. However, the remaining 5.2 percent of the inspected pipe segments had a PACP structural grade of 4 and 5 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. For Items 1 through 21 in the Quick Structural Rating Report Priority List (Enclosure 3) which require a corrective action, the proposed repair or replacement will be scheduled in the next 24 months as part of the ongoing Accumulative Capital Outlay Project. A color-coded map showing the Quick Structural Rating for each pipe segment is located in Enclosure 3. Copies of the actual inspection report for these 21 segments are included in Enclosure 4.

Prior to your plumbing contractor servicing your lateral, please notify the District’s sewer maintenance yard in your area at XXXX to arrange for authorization to access the downstream manhole. During your lateral service, your plumbing contractor must protect the District’s sewer mainlines from dislodged roots and other debris by utilizing catcher baskets at the manhole downstream from your lateral connection. After your lateral has been serviced, please notify the District office, XXXX, Sewer Maintenance Division, at XXXX. For your reference, we have enclosed photos of your lateral connection showing the presence of the root blockage. Also enclosed are some literature on ways of minimizing sewer overflows and damage to your home. Thank you for helping the Department of Public Works keep the public’s sewers clean and in good working order. Very truly yours, GAIL FARBER Director of Public Works KEITH E. LEHTO Assistant Deputy Director Sewer Maintenance Division XX: Enc.

XXXX Roots at Lateral Connection

Minimizing Sewer Overflows and Damage to Your Home The sewer system within the County of Los Angeles Consolidated Sewer Maintenance District (District) is comprised of a series of underground pipes. Many are publicly owned; however, the sewer laterals are entirely owned by the private property owner they serve. The laterals extend from the building to the mainline within the street (or within an easement at the rear of your home). The laterals are typically four inches in diameter while the District’s mainline is typically at least eight inches in diameter. The private property owner is responsible for the entire length of the lateral, which includes the portion that may be located within the public right of way (under the asphalt and street landscaping).

Sewer backups can cause tremendous damage to the interior of a home. In order to minimize these, the District provides continual maintenance services for the public sewer mainlines. Unfortunately, sewer laterals are often not maintained by private property owners until a disaster strikes. “Out of sight, out of mind” is a typical approach to sewer lateral maintenance and operation by many. It is our hope that we can provide you various means of addressing these issues and thus minimize your risk of an overflow entering your home. The three methods we suggest are:

1. Maintain your lateral through proper cleaning, repair, and replacement 2. Do not place improper items into the sewer or make improper connections to the

sewer a. Keep rainwater out of the sewer lines as it overwhelms the capacity of the

sewer lines and may cause sewer spills. b. Do not pour fats, oils, and grease in your drains as these products harden

and stick to the inside of the sewer pipes, which build up and may eventually cause a blockage in the sewer pipe.

3. Install a backflow preventer and cleanout in your sewer lateral.
