CONSOLIDATED SEWER MAINTENANCE DISTRICT PROJECT NAME: Y0TV0809D PROJECT MGR: Eric Liu PROJECT DATE: 01/26/2009 CONTACT NO: (626) 300-3369 SUP. DISTRICT(s): 2 MAP PAGE(S): 1705, 1706,1760 & 1761 Report By: Hanna Kebede Report Date: 03/09/2011 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 199,734 feet or 22.2 percent of the City of Carson’ 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 Y0TV0809D included sewer lines located in the Cities of Carson, Palmdale, Palos Verdes Estates and Rolling Hills Estates and unincorporated County of Los Angeles area. 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
Has failed or will likely fail within the next 5 years
MAINTENANCE REPORT Our inspection revealed that approximately 71.5 percent of the system televised was free of blockages or restrictions that would impede sewer flows. However, the remaining 28.5 percent of the inspected pipe segments within the City of Carson 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). 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.
TOTAL 199,734 100.0 876 High Water Levels Our inspection revealed that approximately 97.3 percent of the system televised has adequate capacity. However, the remaining 2.7 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 of 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. Infiltration Our inspection revealed that approximately 0.5 percent of the system included in this project has infiltration within the pipe segment. Infiltration is the ingress of groundwater into the sewers through a defect or porous area of the pipe wall. All sewer pipes where infiltration has been found are listed on the Infiltration table (Enclosure 2). This table also provides the proposed corrective action for these impacted sewer segments. If a corrective method is proposed, the remediation will be scheduled in the next 24 months as part of the ongoing Accumulative Capital Outlay Project. A map showing the sewer lines with high water levels and infiltration is provided in Enclosure 2. STRUCTURAL REPORT Our inspection revealed that approximately 97.1 percent of the inspected pipe segments within the City of Carson were free of severe structural defects. However, the remaining 2.9 percent of the inspected pipe segments had a PACP structural grade of 4 or 5 as indicated in the Quick Structural Rating Table shown below. The segment has been place on a priority list based on the severity and the need for action. For Items 1 through 24 in the Quick Structural Rating Report Priority List (Enclosure 3) which require a corrective action, the proposed corrective method 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 24 segments are included in Enclosure 4.
FUTURE PROJECTS The Sewer Condition Assessment Program will be performing future closed-circuit television (CCTV) inspection of the remaining sewer lines within the City of Carson according to the following schedule.

IN REPLY PLEASE
REFER TO FILE: SM-1
Current Property Owner 3476 Marengo Ave Altadena, CA 91001 Dear Property Owner: SEWER LATERAL ROOT INTRUSION 3476 MARENGO AVE, 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 3476 Marengo Ave, 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
Current Property Owner August 19, 2010 Page 2 your sewer lateral within 90 days to remove roots and any other obstructions that may cause a sewage backup. Failure to do so may result in future overflows and subject you to civil prosecution, reimbursement costs, and fines up to $1,000. Reference 20.24.160 Violation - Penalty; 20.24.170 Continued violations; 20.32.690 Reimbursement for repairs and maintenance following violations. 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 JOHN T. WALKER Assistant Deputy Director Sewer Maintenance Division PK:

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.
