INTRODUCTION

As part of our Sewer Condition Assessment Program, the County of Los AngelesDepartment of Public Works Consolidated Sewer Maintenance District (District) hascompleted the closed-circuit television (CCTV) inspection of 218,664 feet or23 percent of the City of Carson’s (City) sewer system as part of this conditionassessment report.

To date, the District has completed the CCTV inspection of 420,370 feet or 44.1 percentof the City’s sewer system. In addition to this report, one previous conditionassessment report dated April 12, 2011, was transmitted to your City.A copy of this report can also be found on the District’s website athttp://dpw.lacounty.gov/smd/cctv/city/. The remaining 55.9 percent of the City’s sewersystem is scheduled for CCTV inspection in Fiscal Year 2014-15.

The Sewer Condition Assessment Program utilizes the Pipeline Assessment andCertification Program (PACP Version 6.0.1) Quick Rating methodology to rank thestructural and maintenance condition of your system based on industry standards.

PROJECT AREA AND DESCRIPTION

Project No. Y0TV0910D included sewer lines located in the unincorporated County ofLos Angeles and in the Cities of Carson and Santa Clarita. Enclosed for your referenceis 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 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 detailed breakdownof 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 90.4 percent of the system televised wasfree of blockages or restrictions that would impede sewer flows. However, theremaining 9.6 percent of the inspected pipe segments had a PACP maintenance gradeof 3, 4, or 5 as indicated in the Quick Maintenance Rating Table shown below.These segments have been incorporated into our enhanced maintenance schedule withcorrective 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 pipesegment is provided in Enclosure 2.

Lateral Notices

Also included on the Quick Maintenance Rating Report Priority List are deficienciesdiscovered inside lateral connections to the mainline. The District does not maintainlateral lines. It is the responsibility of the property owner to maintain their respectivelateral lines to facilitate the flow of wastewater from their property to the mainline.As a result of this condition assessment, 37 notices will be sent to property owners inyour City notifying them of the maintenance issues discovered in their lateral. A samplelateral notice letter is provided in Enclosure 2 for your reference.

High Water Levels

Our inspection revealed that approximately 97.3 percent of the system televised hasadequate capacity. Approximately 2.7 percent of the segments inspected exhibiteddeficiencies associated with high water levels. Capacity of the sewer pipe can bedetermined by analyzing several PACP codes, including Water Level, Water Mark, andmiscellaneous remarks, which indicated the camera was underwater or there were sagsin the line. A sewer pipe is typically considered at capacity when the sewer pipe isflowing half full. However, there are conditions in which the water level or water markhas reached 50 percent of capacity or greater due to heavy flows in adjoining pipes, atemporary stoppage due to debris in the sewer lines, or a sag in the line. Therefore,additional review of the pipe segments exhibiting high water level concerns wasconducted to determine if any capacity issues exist. The sewer segments associatedwith high water levels appear to be the result of sags in the line, which do not impact itscapacity. The pipe segments with sags have been cleaned to remove any debris in theline.

All sewer pipes where Water Level, Water Mark, and miscellaneous remarks of cameraunderwater or sags in the line are at or above 50 percent capacity, have been listed andanalyzed on the High Water Level Table in Enclosure 2. The nature of these high waterlevel conditions is also summarized on this table.

Infiltration

Our inspection revealed that approximately 0.2 percent of the system included in thisproject has infiltration within the pipe segment. Infiltration is the ingress of groundwaterinto the sewers through a defect or porous area of the pipe wall. All sewer pipes whereinfiltration was found are listed on the Infiltration Table (Enclosure 2). This table alsoprovides the proposed corrective action for these impacted sewer segments.If a corrective method is proposed, the remediation will be scheduled in the next24 months as part of our ongoing Accumulative Capital Outlay Program.

A map showing the sewer lines with high water levels and infiltration is provided inEnclosure 2.

of 4

STRUCTURAL REPORT

Our inspection revealed that approximately 94.9 percent of the inspected pipe segmentswithin the City were free of severe structural defects. The remaining 5.1 percent of theinspected pipe segments had a PACP structural grade of 4 and 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 47 in theQuick Structural Rating Report Priority List (Enclosure 3), which require a correctiveaction, the proposed repair or replacement will be scheduled in the next 24 months aspart of our ongoing Accumulative Capital Outlay Program.

A color-coded map showing the Quick Structural Rating for each pipe segment islocated in Enclosure 3. Copies of the actual inspection report for these 47 segmentsare included in Enclosure 4. A map showing the sewer lines that need lining and pointrepair is also provided in Enclosure 3.

Dear Property Owner:

SEWER LATERAL ROOT INTRUSION

As the agency responsible for the maintenance of the sanitary sewer system in yourarea, the County of Los Angeles Consolidated Sewer Maintenance District (District) isproviding you with this courtesy notice informing you that the sewer lateral serving theproperty located at XXXX, requires maintenance per County Code 20.24.080Maintenance of Sewer Laterals.

“All house laterals, industrial connection sewers, septic tank outlet connectionsto STEP system, and appurtenances thereto existing as of January 23, 1953, orthereafter constructed, shall be maintained by the owner of the property served ina safe and sanitary condition, and all devices or safeguards which are required bythis Division 2 for the operation thereof shall be maintained in good workingorder.”

Using closed-circuit television (CCTV) camera technology, the District recently televisedthe sanitary sewer mainline and discovered the presence of roots in your sewer lateralconnection. The intrusion of the roots from your lateral may block the flow of sewage inthe mainline sewer causing a sanitary sewer overflow upstream of your property.

Since the CCTV inspection, the sewer mainline has been cleaned and blockages fromroot growth have been removed; however, the root blockage in your sewer lateral is stillpresent. As the property owner, you are responsible for the entire length of the sewerlateral, which includes the portion that extends beyond the property line into the publicright of way. We request that you contact a qualified plumbing contractor to serviceyour sewer lateral within 90 days to remove roots and any other obstructions that maycause a sewage backup.

SAMPLE

Prior to your plumbing contractor servicing your lateral, please notify the District’s sewermaintenance yard in your area at (XXX) XXX-XXXX to arrange for authorization toaccess the downstream manhole.

During your lateral service, your plumbing contractor must protect the District’s sewermainlines from dislodged roots and other debris by utilizing catcher baskets at themanhole downstream from your lateral connection.

After your lateral has been serviced, please notify 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 thepresence of the root blockage. Also enclosed are some literature on ways of minimizingsewer overflows and damage to your home.

Thank you for helping the Department of Public Works keep the public’s sewers cleanand in good working order.

Very truly yours,

Minimizing Sewer Overflows and Damage to Your Home

The sewer system within the County of Los Angeles Consolidated Sewer MaintenanceDistrict (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 easementat the rear of your home). The laterals are typically four inches in diameter while theDistrict’s mainline is typically at least eight inches in diameter. The private property owneris responsible for the entire length of the lateral, which includes the portion that may belocated 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 tominimize these, the District provides continual maintenance services for the public sewermainlines.

Unfortunately, sewer laterals are often not maintained by private property owners until adisaster strikes. “Out of sight, out of mind” is a typical approach to sewer lateralmaintenance and operation by many. It is our hope that we can provide you various meansof 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 replacement2. Do not place improper items into the sewer or make improper connections to the

sewera. 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 eventuallycause a blockage in the sewer pipe.

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