2 The City s municipal facility source inventory showing key fields is included as Appendix A. No changes to the designated municipal minimum BMPs detailed in the City s Local Implementation Plan were made during the reporting period. No new flood management projects were completed during the reporting period. The City does not maintain flood management devices beyond the storm drain system. The flood control channel in Laguna Canyon Creek is maintained by the Orange County Flood Control District. All flood control projects undertaken in the City must obtain approval through the Community Development, Public Works and Water Quality Departments as would any project in an identified ESA. Municipal BMPs Urban water diversion units are key BMPs in the City. Diversion units connect the storm drain system to the sewer system so that dry weather nuisance flows may be diverted away from the receiving waters to the sanitary sewer system. Diversions are used in conjunction with Continuous Deflection Separation () units which collect trash, cigarette butts, organics, sludge and floatables for removal during maintenance operations.

3 Currently, the City maintains 21 diversion structures which cover the highest priority watersheds. Diversions provide a final safety net to protect receiving waters from pollution from storm drains. Illicit discharges, accidental spills, groundwater inflow and nuisance water flows are all sent to the sewer system for treatment.

4 Map 3-1 Diversion Unit Coverage Areas Diversion maintenance includes monthly cleanings and inspections as well as seasonal activation and deactivation. Diversions Citywide were deactivated on October 11, 2011 and activated on April 26, 2012 for a total of 165 days online during the reporting period. An estimated 135,000 gallons of nuisance flows were cleaned and diverted each day for an estimated total of 22 million gallons for the reporting period. All diversion inspection and cleaning activities are tracked in the City s Lucity Computerized Maintenance Management System database. Sewer System Maintenance City sewer crews operate on a rotational schedule to clean all City-owned sewer lines at least once per year. Select sewer lines are scheduled for biannual and quarterly cleanings in areas identified as susceptible to blockage. Cleaning lines regularly prevents sewer spills and aids sewer crews in identifying problems such as offsets and collapses. More than 80% of City owned sewer lines and manholes have been lined within the last ten years. Sewer maintenance prevents infiltration of sewage and sewer spills. The City s Sewer System Management Plan (SSMP) is available online at The City also employs the following controls to prevent infiltration of seepage from municipal sanitary sewers to municipal separate storm sewer systems: Laguna Beach Stormwater Program 3-3 December 18, 2012

5 Design and Performance Provisions for the installation of new sanitary sewer systems, pump stations and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems; procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects to meet the requirements of the APWA "Green Book" and building codes. Staff incident response training in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained prior to starting work; Operation and Maintenance Program with updated mapping of sanitary sewer system; scheduled part replacement; rehabilitation plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. Routine inspections and video filming to check the sewer lines condition to avoid the potential of clogs, backups, or breaks that could result in a seepage or discharge to the MS4. Sanitary Sewer Management Plan Program Audits Communication Program with the public and South Coast Water District on the development, implementation, and performance of its SSMP. Fats, Oils and Grease Program Sanitary sewer overflows are a serious problem in sewer systems throughout Orange County and, in coastal cities, have resulted in many beach closures. The Grand Jury recently issued a report noting grease as one of the most prevalent causes of sewer overflows. An analysis of overflows in the City of Laguna Beach sewer system, between 1997 and 2000, revealed that roots and grease are the two primary causes of spills. The private sewer lateral program is underway to address the roots in the sewer system, which historically has been responsible for approximately 60% of overflows. Grease, another potential cause of spills, historically has been responsible for an estimated 25% of sewer overflows. Grease in the sewer system is generated in large quantities by food preparation facilities, such as restaurants and grocery store delis that sell food for immediate consumption. Grease from food preparation and cooking coagulates in the sewer pipes when it cools down and can restrict the flow of wastewater. Restricted flow causes solid material in the pipe to accumulate, resulting in blockages and wastewater spills. The City Council, in enacting the grease ordinance (Title 17, Chapter of Municipal Code), intends to provide for the maximum beneficial public use of the city s sewer system, to prevent blockages of that system and the accidental discharge of wastewater into the storm drain system or the Pacific Ocean, to ensure the cost of maintaining the city s sewer system is equitably distributed among users, to clarify grease disposal requirements for existing food service establishments, and to promote public health and safety. It is the purpose and intent of the grease control program, or FOG program, to establish regulations for the disposal of grease and other insoluble waste discharges from food service establishments within the city. The grease ordinance requires employees of all food service Laguna Beach Stormwater Program 3-4 December 18, 2012

6 establishments to be trained twice each calendar year in best management practices. Properly sized subterranean grease interceptors are required for ALL RESTAURANTS during change of ownership, remodel or new establishment. On June 12, 2001, the City Council awarded a contract to Environmental Compliance Inspection Services (ECIS) to inspect and monitor food preparation establishments in the City s service area. As the City's designated FOG inspector, this contractor is authorized to inspect establishments and enforce the Grease Ordinance using all legal means. Private Sewer Lateral Program The City reviews videotape of the sewer to determine the condition of the pipes. During the review process, City staff notes serious problems with the private laterals leading to homes. Problems can cause sewage to back up into homes or could break off and enter the City s sewer system and cause a sewer spill. The City recommends that homeowners contact a plumbing company to have private sewer laterals video inspected to determine whether the lateral needs to be cleaned, repaired or replaced. Once the necessary corrective measures are completed, the City recommends property owners provide written documentation of the repair to be recorded in the property file. It is the owner s responsibility to maintain the private sewer lateral from the home or business to the connection with the City s sewer system. Property owners may be fined if a sewer spill occurs due to the lack of maintenance. The City s private sewer lateral program ordinance is available at Capital Projects During the reporting Period, the City completed the fourth phase of the Heisler Park ASBS Protection and Preservation Project. This phase was the construction of a new sewer lift station at the North end of Main Beach. This new lift station is equipped with redundant pumps, automated controls, electronic monitoring and alarms. The new pump station will significantly reduce the threat of sewage spills to Main Beach which is located next to the Heisler Park Area of Special Biological Significance. In addition to the Main Beach lift stations, two new urban water diversion units were installed in the City. These units will capture nuisance dry weather flows from 153 acres and divert the runoff to the sanitary sewer system. These diversion units are expected to reduce the amount of sediment, indicator bacteria, pesticides and other runoff related pollutants from reaching local beaches and ocean waters. The City of Laguna Beach has provided over $2,500,000 in matching funds combined with over $1,000,000 in grant funding to construct the projects.

7 Street Sweeping The City s street sweeping maps are included in Appendix C. Streets are swept daily on a rotating schedule. In addition to the rotating schedule, targeted areas such as downtown are swept daily. An estimated 13,000 miles were swept with an estimated 230 tons of debris disposed of by Waste Management. All street sweeping tracking data is being integrated into the water quality database during the reporting period. Catch Basin Maintenance Each year, pre-rainy season, all 921 City-owned catch basins are cleaned by streets crews and waste is disposed of by Waste Management. Household Hazardous Waste City residents can have their household hazardous waste picked up right at the doorstep on demand, year-round. Residents are allowed one free pickup per calendar year. Residents call HHW-PKUP ( ) and ask for the next available pick-up date in Laguna Beach or visit to scheduled pickup. The City's contractor, Curbside Inc., will send residents a kit and instructions prior to the scheduled collection date.
