CONDITION ASSESSMENT REPORT COUNTY OF LOS ANGELES DEPARTMENT OF PUBLIC WORKS

CONSOLIDATED SEWER MAINTENANCE DISTRICT PROJECT NAME: Y0TV1011B PROJECT MGR: Hanna Kebede PROJECT DATE: 08/08/2011 CONTACT NO: (626) 300-4686 SUP. DISTRICT(s): 5 MAP PAGE(S): 2017 & 2018 Report By: Hanna Kebede Report Date: 09/26/2011 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 15,194 feet or 3.8 percent of the City of Temple City’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 Y0TV1011B included sewer lines located in the Unincorporated County of Los Angeles area and in the Cities of Pico Rivera, Santa Fe Springs and Lakewood. 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: Defects requiring immediate attention.

Has failed or will likely fail within the next 5 years

MAINTENANCE REPORT Our inspection revealed that approximately 91.1 percent of the system televised was free of blockages or restrictions that would impede sewer flows. However, the remaining 8.9 percent of the inspected pipe segments within the City of Temple City area had a PACP maintenance grade of 3 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 on this 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. In addition, a color-coded map showing the quick maintenance rating for each pipe segment is provided in Enclosure 2.

REFER TO FILE: SM-1

Glenn Jeanes 1570 Morada Place Altadena, CA 91001 Dear Mr. Jeanes: SEWER LATERAL ROOT INTRUSION 1570 MORADA PLACE, ALTADENA, CALIFORNIA 91001 As the agency responsible for the maintenance of the sanitary sewer system in your area, the County of Los Angeles Consolidated Sewer Maintenance District (District) is providing you with this letter informing you that the sewer lateral serving the property located at 1570 Morada Place, Altadena, California 91001, requires maintenance and is in violation of County Code 20.24.080 Maintenance of Sewer Laterals, which states: “All house laterals, industrial connection sewers, septic tank outlet connections to STEP system, and appurtenances thereto existing as of January 23, 1953, or thereafter constructed, shall be maintained by the owner of the property served in a safe and sanitary condition, and all devices or safeguards which are required by this Division 2 for the operation thereof shall be maintained in good working order.” Using closed-circuit television (CCTV) camera technology, the District recently televised the sanitary sewer mainline and discovered the presence of roots in your sewer lateral connection. The intrusion of the roots from your lateral may block the flow of sewage in the mainline sewer causing a sanitary sewer overflow upstream of your property. Since the CCTV inspection, the sewer mainline has been cleaned and blockages from root growth have been removed; however, the root blockage in your sewer lateral is still present. As the property owner, you are responsible for the entire length of the sewer lateral, which includes the portion that extends beyond the property line into the public right of way. We request that you contact a qualified plumbing contractor to service

Glenn Jeanes May 26, 2011 Page 2 your sewer lateral within 90 days to remove roots and any other obstructions that may cause a sewage backup. Prior to your plumbing contractor servicing your lateral, please notify the District’s sewer maintenance yard in your area at (626) 446-5227 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, Mr. Fernando Villaluna, Sewer Maintenance Division, at (626) 300-3380 or [email protected]. 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 LEHTO Assistant Deputy Director Sewer Maintenance Division EL:

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 that 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.
