Receive a presentation on infrastructure condition. 2. Discuss various options related to the creation of a long-term public infrastructure management and financing plan and direct staff to distribute a request for proposals from qualified firms to prepare an infrastructure management plan. BACKGROUND Your Public Works and Finance and Information Technology departments have prepared a workshop presentation for the City Council and community on the subject of infrastructure management and financing. Public Works will present a summary infrastructure report card, which grades several categories of public improvements, and Finance will present information how funding and financing considerations are integrated into an infrastructure management plan. 1-1 RPV INFRASTRUCTURE WORKSHOP PAGE 2 OF 3 DISCUSSION Public infrastructure involves planned maintenance and repairs, occasional alteration or expansion, and in some situations rehabilitation or replacement of public improvements in order to meetthe goals, needs, and expectations of the community. When a community addresses aging and deteriorating infrastructure in a practical and timely manner, it can result in significant cost savings for future residents and community members. It is recommended that a public process involving an infrastructure report card and an infrastructure management plan that includes funding and financing considerations be implemented to provide the City Council with policy choices and leadership options. What is an Infrastructure Report Card? An infrastructure report card is an assessment of the current condition of the existing public improvements of a community. It is a snapshot in a moment of time: it does not evaluate community needs and priorities nor is it an in-depth assessment. It is a data- driven, objective review of our public improvements that grades the existing state of the infrastructure in a city on an established scale from Exceptional ("A") to Failing ("F"). The grades are selected based on criterion developed by the American Society of Civil Engineers (ASCE) guidelines that have been consistently used for almost two decades. The report card presented today is a summary of the grading ascertained for all known RPV public improvements. It was prepared by SA Associates, a consulting engineering firm, located in Arcadia. The President of the firm has been involved with the ASCE Infrastructure Report Cards developed for Los Angeles County and California. The report card being presented today is tailored on similar report cards prepared for the counties of Los Angeles, Orange, and San Diego. The backup documentation of the condition of each item will be available on the city's website in early March. SA Associates indicates that RPV is the only local municipality that the firm has prepared a report card and perhaps one of the first non-urban California cities to do so. The public improvements graded include our public buildings and park sites, trails, storm water and sanitary sewer systems (including the Abalone Cove Assessment District), right-of-way and traffic control devices, and the Palos Verdes Drive South landslide. Infrastructure Management Plan The report card is the stepping stone for the preparation of an integrated infrastructure management plan (or IMP), which is used by cities and counties to chronicle the in-depth condition of its public infrastructure and chart an operations and financial course for the actions and funding required to maintain and preserve community public property. Such a plan addresses community needs and sustains vital services over the long term by keeping the aging and deteriorating infrastructure in good condition, thereby reducing cost and effort over the long term. The integration of the General Plan, community needs, policy, economics, and risk makes the IMP more comprehensive than a typical 5-year capital improvement program. The IMP provides an opportunity to determine the impact of different funding 1-2 RPV INFRASTRUCTURE WORKSHOP PAGE 30F 3 strategies/scenarios and prioritization on project delivery over the course of multiple planning decades. One of the outcomes from the preparation of the IMP is a reality-based capital improvement program. The IMP would include detailed assessments of the long-term condition of public improvements and a comprehensive study of the community's current and future needs (including public safety and regulatory mandates) and an identification of the maintenance level required for each public asset based on community expectations. The IMP also calculates the resources and funding shortfalls and recommendations of city council policies to assist with program implementation, goal-setting, and prioritization. Community Involvement Process It is recommended that following the presentation of the infrastructure report card the City Council direct staff to distribute a request for proposals from qualified firms to prepare an infrastructure management plan that includes a series of study sessions and community workshops to drill-down into the condition of one infrastructure category. FISCAL IMPACT There is no immediate fiscal impact from this workshop. The cost to prepare the IMP framework and perform the first in-depth assessment of one report card category is estimated to be between $35,000 and $75,000. CONCLUSION The infrastructure systems of Rancho Palos Verdes should be built, maintained, and upgraded on a continuous basis for the community to thrive. These investments result in long term savings and positive growth, benefiting our present community for generations to come. Attachment: RPV Infrastructure Report Card 1-3 1-4 1-5 1-6 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD FOREWORD It is with great pleasure that we present this 2013 Infrastructure Report Card to the City of Rancho Palos Verdes. Infrastructure is designed and maintained by engineers and can be defined as: The basic physical and organizational structures and facilities (e.g., buildings, roads, and utilities) needed for the operation of a society or enterprise. This report card is an assessment of the existing condition of infrastructure in the City. It is a snapshot in a moment of time: it does not evaluate community needs and priorities nor is it an in-depth assessment. It is a data-driven, objective, professional review that grades the existing state of the infrastructure on an established scale from Exceptional (A) to Failing (F), based on the American Society of Civil Engineers (ASCE) guidelines and standard criterion. / ; The assessed infrastructure components in this report are: the City's Public Buildings, Park Sites, Trails, Storm Water System, Sanitary Sewer System, Abalone Cove Assessment District S,eWer System, Right of Way and Traffic Devices, and Palos Verdes Drive South Landslide. / / This report card suggests improvements to raise the existing infrastructure condition one grade up and to raise its grade to Exceptional ("A"). To calculate the cost estimat~~ associated with these two upgrades, an / Infrastructure Management Program (IMP) is recommende<;I. While this report card assesses the current condition of the infrastructure, and provide recommendations to improve it, an IMP will provide a comprehensive cost estimate of the current and future needs on a long term basis, will identify the maintenance level required for each infrastructu~e· component, will identify the resources, the funding shortfalls, and will identify prioritization of proje~ts and expenditures. / This report card reflects a collaborative effort by SA Associates and City staff, including members of Public Works, Traffic/Right-of-Way, Water Qusilrty, Parks and Building Facilities, and Community Development. / In spite of the current state of the, economy, it is the responsibility of engineers and our fellow citizens to know the state of our infrastru.dure and to work towards improving it. As engineers, it is important that we inform our public on the in,:ip~rtance of infrastructure maintenance, and encourage our colleagues in the public sector to continu,71o seek infrastructure funding. We should not underestimate the importance of infrastructure in our lives. It is essential to our way of life, our economy, and our health and wellbeing. Warmest Regards, Shahnawaz Ahmad, P.E.

' 1-8 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD SECTION 1: INTRODUCTION 1.1 PURPOSE The City retained SA Associates to evaluate the condition of the City's existing infrastructure and to prepare an assessment of the existing condition of infrastructure in the City. This Report Card reflects the findings of that analysis. The grades associated with each infrastructure component help the City prioritize its infrastructural needs, help organize its decision making process, and also build a base for the preparation of the City's Infrastructure Management Program. City staff provided support and feedback to SA Associates during the preparation of this report. 1.2 CITY BACKGROUND The City of Rancho Palos Verdes is located in the southwestern most portion of Los Angeles County. It is bounded on the northwest by the City of Palos Verdes Estates, on the east by the 12ity of Los Angles (San Pedro), on the north by the Cities of Rolling Hills and Rolling Hills Estates, and on t~e"south and southwest by the Pacific Ocean. / / At the close of the 19th Century, the Palos Verdes Peninsula was inhabited solely by a few cattle ranchers and sheepherders. The land was mostly covered with nothing more than native vegetation. Then, for a brief period in the early 1900s, the Peninsula enjoyed prosperity not qnly as a cattle ranch, but also as a rich farming area. Japanese immigrant families farmed the most southern slopes, growing fields of beans, peas and tomatoes, while the manager of the cattle ranch grew ~aHey for hay and grain on the dryer northern slopes. In 1913, Frank A. Vanderlip, president of the National Bank of New York, purchased the 16,000-acre Palos Verdes Peninsula with a vision to develop the "m6st fashionable and exclusive residential colony" in , the nation. Unfortunately, his dream was put on ho)d after the Stock Market Crash, the Great Depression, and the onset of World War II. None of these SE?tbacks, however, reduced the beauty of the Palos Verdes Peninsula, or its potential desirability as a resi~ential area. , The city boundaries contain approximately 13.6 square miles of area and 7.5 miles of coastline. The reported / population in 2000 was 41,145 and t,his is estimated to have increased to 42,800 in 2009.The population is not expected to increase dramatJcally as only a small number of vacant areas remain for development. Future developments and/or re(:levelopments that do occur will likely have limited impact on the overall population. The City is curr,ently revising its General Plan and there is a strong community feeling that the semi-rural nature of the community should be preserved. Today, as a result of the foresight of its founders and residents, the City,of Rancho Palos Verdes continues to offer magnificent views, open spaces, clean air, and remains an extremely desirable place to live. 1-9 Figure 1.1: City shoreline CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD , 2013 The climate of the City is Mediterranean with average annual rainfall of 13.17 inches. The majority of this rainfall occurs during January, February, and March. The steep terrain of the Cjl:f allows most of the rainfall to drain quickly with little observed surface flooding. The average temperature varies from 67!! F in the / winter to 80!! F in the summer. / / / / / / / / / , / / / / 1-10 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD 1.3 CITY INFRASTRUCTURE The City owns and/or maintains an extensive infrastructure system consisting of sewers, storm drains, roads, parks, trails, and buildings.

Identify Categories 2. Conduct Visits & Gather Information 3. Identify Grading Criteria 4. Review Available Documents 5. Assign Preliminary Grade for Review by Review Committee 6. Assign Final Grade 2013 The Infrastructure Report Card Working Group (Working Group); comprised of engineers specialized in the assessed infrastructure categories, worked closely with the City staff to identify the categories to be considered in the report card. Site visits, for all categories, were conducted and photos were taken for documentation. Information about each category was gathered, reviewed and categorized. The information included: master plans, master plan updates, studies, third party consultant reports, City staff reports, City staff presentations, survey plans, rehabilitation plans, City website, City budgets, City capital improvement plan, etc. The documents reviewed for each category are listed at the end of each category section under the heading "Sources". After many hours of review and analysis, the Working Group assigned a preliminary grade to each category. For the buildings and the parks, individual grades were assigned for each building/park and an overall grade was calculated based on the individual grades. The assigned grades were based on the reviewed City documents, the reports/studies prepared by third party consultants, and the findings of the site visits. The grades and the support material were reviewed by the "Review Committee" responsible for the quality assurance/quality control of the Report Card. The review committee included professional engineers specialized in the field of infrastructure. The Review Committee comments were discussed/implemented and the final grades were assigned. The assessment/grading was conducted for the existing facilities in the City and was based on the facilities current condition. Future plans were not taken into consideration in the grading process. However, they were considered in defining the future recommendations. 2.2 DEFINITION OF THE GRADES The infrastructure report card utilizes grading criterion that the general public can relate to, similar to the grading used in education. This is the grading criterion used by The American Society of Civil Engineers (ASCE) in infrastructure grading. 1-12 2013 Grade A B c D F CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD / / / Percentage 90-100% 80-89% 70-79% 41-69% 40%orlower / / , / / / Definition Exceptional Good Average Poor Failing / / / / / / / / / 1-13 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD SECTION 3: REPORT CARD SUMMARY 2013 The following are summaries of the different infrastructure components and their associated grades: Public Buildings: D The City of Rancho Palos Verdes owns a total of 17 public facilities, located within park sites, with a total square footage of 68,819. Most of the public buildings are 25 years old or older and were purchased from school districts or transferred to the City from the federal government. The criteria of evaluation of the public buildings was based on (1) the structural/seismic condition of the building, (2) the condition of exterior and interior finishes, (3) the functionality/operability of the building's systems including electrical, plumbing, heating ventilation and air conditioning (HVAC), and firefighting, (4) safety issues, and (5) sustainability and energy saving. The Overall Grade for the public buildings is D. This shows a great need for retrofitting/renovation of the public buildings. ,,- ; Park Sites: B / The city has 16 parks, 3 recreational active, 12 recreational passive, and l:lnstitutional educational, with a total acreage of about 186 acres. In addition to housing the City's community centers, the active parks provide sports and recreational facilities; tot lots, playgrounds, tennis courts, baseball diamonds, grassy fields, and picnic areas. Some parks also serve as trailheads for the/trails system serving the cities of Rancho Palos Verdes, Rolling Hills, Rolling Hills Estates, and Palos Verdes Estates. Parks are maintained by outside vendors retained by the City under the supervision of the Public Works Department. Other park activities and rentals are managed by the Recreation and Parks Department. The City parks were assessed based on (1) the condition of the available infrastructure, (l) the condition of the existing facilities (tot lots, playgrounds, benches, picnic tables, drinking foul)tcllns, and sports facilities), and (3) the assigned parking. The assessment showed more than 70% of the,,Parks in excellent condition. The Overall Grade for the park sites is B. It is important to mention that the current condition of the City parks is the result of the recent improvement/renovation projects. Maintaining this grade requires the continuity of these projects. / Trails: A / The City's trails network syster;, includes: (1) 101 Preserve trails about 29 miles in length, within the / approximately 1,400 acre .Palos Verdes Nature Preserve (Preserve). The Palos Verdes Peninsula Land Conservancy (PVPLC) is /re'sponsible for the maintenance and repair of existing unimproved trails in the Preserve while the City is responsible for the construction of new trails and maintenance of improved trails. Preserve trails are generally maintained by volunteer crews. (2) 16 currently operating Non-Preserve Trails, about 3 miles, within the City's open spaces, managed and maintained by the City. The trails are designated for specific users. They are either pedestrian, cyclists, equestrians, a combination of any two, or multipurpose trails designated for the three types of users. The assessment of the trails was based on (1) the available access points and trail markers/signage, (2) available parking, (3) connectivity, and (4) maintenance. The assessment showed the trails in a very good condition. The Overall Grade for the trails is A. Storm Water System: C The City's storm water system consists of buried pipes, open channels, catch basins, inlets, and outlets strategically placed within the City to drain water from properties and roads. For the City's storm water system, the capacity, condition, operation and maintenance, and environmental sustainability of the system were evaluated for grading purposes. Age is a significant factor in the evaluation of grading since a newer SA Is 1-14 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD system reflects both a capacity to accept the drainage flows and the condition to carry it properly. Since most of the City's drainage facilities were constructed by the Los Angeles County Department of Public Works prior to incorporation of the City, the City's drainage capacity is lacking in certain areas. However, due to the City's investments, the storm water system provides functionality. With the completion of the Mccarroll Canyon system and the San Ramon project currently under construction, the City is making strides to begin managing its many uncontrolled canyons. Thus, overall grade was determined to be C. This shows a need for improving the City's storm water system. Citywide Sanitary Sewer System: D The City's overall sewer system consists of sewer mainlines, laterals, manholes, lift stations, and grinder pumps. The City's sewer mainlines consist mostly of gravity pipelines constructed with vitrified clay pipe (VCP), with some force mains (pressure pipe) that transmit sewage from low elevation points. For the City's sanitary sewer system, the capacity, condition, operation and maintenance, and environmental sustainability of the system were evaluated for grading purposes. For sewer systems, age is a more significant factor in the evaluation of grading than with storm drain systems since the age of sewers typically~eflects the capacity to properly transmit flows. A damaged sewer system cannot transmit flows properly, and wastewater must be transmitted and disposed of properly. Also, an older sewer system is likely io' reflect inferior construction standards as well as deteriorated pipelines. Despite the age of the City's S!=i!Wer system, the system provides acceptable functionality. Thus, overall grade was determined to be D. This shows a fairly strong need for improving the City's sewer system. Abalone Cove Assessment District Sewer System: D / The City's Abalone Cove Assessment Sewer System is considered part of the sewer system in the 2009 Master Plan but for billing and maintenance purposes it is cori.sidered a separate sewer system. The Abalone Cove Assessment Sewer District System consists of sewer mainlines, laterals, manholes, grinder pumps, and 4 lift stations. For the system, the capacity, concjjtion, operation and maintenance, and environmental sustainability were evaluated for grading P\Jri>oses. Since the system was constructed in 2001 to help minimize water infiltration into the landslide area and to replace septic systems, the capacity and condition of the system were more heavily weighE:!d. The system is constructed using polyvinyl chloride (PVC) and Polyethylene (PE) pipe, due to the as:tlve landslide, however, vitrified clay pipe (VCP) is used in some areas. Despite the threat of landslide, th,e'system currently has good capacity and condition. However, the system is highly vulnerable to land movement and mechanical wear, and requires a high degree of maintenance, and provides slightly less than d.esfred functionality. Thus, the overall grade was determined to be D. This shows a strong need for impro~in'g the District sewer system. Right of Way and Traffic Devices: A The City's right of way network consists of local streets and arterials, including pavement, medians, curb, gutter, sidewalk, street lights/signals, and right of way landscaping (i.e. median trees). In terms of length, the majority of City roadways consist of local streets (i.e. residential), as local streets comprise nearly 75% of the total length of roadways in the City. Arterials comprise 25% of the total length of roadways in the City. For the City's right of way system, the capacity, condition, operation and maintenance, and environmental sustainability of the system were evaluated for grading purposes. For right of way/street systems, the condition is perhaps the primary aspect of concern to residents and City officials, as deteriorated pavement poses a threat to the safety of not only motorists, but bicyclists and pedestrians in particular. Due to the City's strong CIP program and excellent operation and maintenance procedures, the City's streets are in great condition and provide exceptional functionality. Thus, the overall grade was determined to be A. This shows that the City's right of way system is in good condition. 1-15 Palos Verdes Drive South Landslide: D CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD 2013 An important portion of the City lies within a natural landslide area that is composed of several component landslides. It is mainly located at Palos Verdes Drive South, an important arterial that connects the east part of the city. The landslide affects not only surface streets and buildings, but also other infrastructure as well, including much needed utilities. The City has established mitigation infrastructure and improvements as part of efforts to slow the rate of the landslides and to minimize the likelihood of catastrophic landslide movements. This mitigation infrastructure consists of, grading, and dewatering wells in addition to drainage and sewer systems. The mitigation infrastructure was evaluated based on the capacity of the infrastructure to prevent or slow subsurface land movement, the condition of the infrastructure as it relates to operation and maintenance, and the environmental impacts as it relates to maintaining dwellings, landscapes, and utilities, and protecting the public from harm. For the City's landslide mitigation infrastructure, only the, grading, and dewatering wells were evaluated since drainage and sewer infrastructure were evaluated in previous sections. Although the individual mitigation infrastructure is proving to slow landslide movements, it does not fully meet the needs of the City and provides inadequate functionality . Thus, the overall grade was determined to be D. This shows a very strong need for improving the Cit/s landslide mitigation infrastructure.

The City's infrastructure benefits all of the City's citizens as well as its visitors . The City's infrastructure is vital to not only the City's economy but also to the Palos Verdes Peninsula as a whole. In addition to its economic importance, the quality of the City's infrastructure also has significant recreational and social benefits, which include community centers, trails, and parks. / / Figure 3.1: Seascape Trail at Vicente Bluff Reserve / As with any home, each infrastructure system needs to be m;iintained and upgraded on a continuous basis . Infrastructure system failures can cause disruptions to our daily lives, trigger slow-downs in economic activity, or even be the cause of injury and death. For,6ample, a roadway failure could cause widespread traffic jams, disrupt access to buildings and hospitals~ and could also result in fatal injury . Proper care of our / cities, including maintaining our roads, upgradiµg storm water and sewer systems, and having regularly evaluated and maintained systems, goes a longway. These investments will benefit our present community for generations to come . ;' / This assessment oft he current condition of the City's infrastructure is an indicator on how the City is currently / doing and how it should act in theAuture. / This report card is a tool t_p ~elf-appraisal that will empower the tracking of the current trends and the forecasting of the City's future .

These costs can better be considered as investments. Investment decisions are based on a priority needs basis, through reports by City staff. These decisions are mostly recommended by City staff and reviewed and approved by the City Council. The following are average annual investments made to each infrastructure category over the past three years: •!• Public Buildings Average 2010-2013 Expenditures: $475,000/year •!• Park Sites Average 2010-2013 Expenditures: $1.4 million/year •!• Trails Average 2010-2013 Expenditures: $70,000/year •!• Storm Water System Average 2010-2013 Expenditures: $2.5 million/year •!• Sanitary Sewer System Average 2010-2013 Expenditures: $90,000/year •!• Abalone Cove Assessment District Sewer System Average 2010-2013 Expenditures: $77,000/year •!• Right of Way and Traffic Devices / Average 2010-2013 Expenditures: $4 million /year " •!• Pa l os Verdes Drive South Landslide (and dewateri ng we lls} Ave rage 2010-2013 Expenditures: $700,000/,ve'ar / / These numbers can fluctuate over a given time ye'riod from under $100,000 to over $5 million based on the needs of the City's infrastructure.

The upgrade also includes the necessary ADA Compliance improvements for items identified as the "Potential Safety Hazard" and "Severe" barriers (the most severe) in the City's ADAA~sessment Compliance Report. / / To upgrade the public biylcJings to A, the City needs to perform complete retrofitting ofthe City Hall Buildings and Ladera Linda Community Center Buildings and new solar power system for PVIC and Fred Hesse Buildings. The upgrade shall also include all ADA compliance retrofitting for all buildings. The cost estimate of the investment needs will be determined in the Infrastructure Management Program . Although the complete retrofitting for City Hall Buildings!2l and Ladera Linda Community Buildings!3l will result in modernized energy efficient buildings with an expected useful life of at least 20 years, the inherent constraints of the structure's layout will remain and the area (square footage) will remain the same. Another alternative is the complete replacement of these buildings. This will result in brand new, state-of-the-art green and sustainable civic and community centers, which reflect the city's spirit of environment and habitat preservation, and accommodate the city's future space needs. The replacement cost for the City Hall buildings, and for Ladera Linda community buildings can be estimated in the Infrastructure Management Program. Funding for the City-owned infrastructure, including streets, parks, sewers, and buildings comes from various 1s j SA 1-21 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD 2013 sources; including transfers from the General Fund and restricted funds, and grants from other governmental agencies. The annual budget for buildings maintenance is in the range of $SOO,OOO. FY13-14 budget is around $600,000. Recommendations 1. Develop a comprehensive long term maintenance plan that ensures the continuous maintenance and renovation of the buildings to extend their useful life, enhance their functionality, improve their efficiency, and minimize their impact on the environment 2. Secure funding sources for maintenance, renovation or replacement of existing buildings and construction of new buildings. / 3.

In addition to housing the City's community centers, the parks provide sports and recreational facilities; tot lots, playgrounds, tennis courts, baseball diamonds, grassy fields, and picnic areas. The parks also serve as trailheads for the trails system serving the cities of Rancho Palos Verdes, Rolling Hills, Rolling Hills Estates, and Palos Verdes Estates. The City is the home of stunning scenic ocean views, whale watching, hiking, biking, equestrian activities, hands-on environmental exploration, and picnicking. The City's residents are exceptionally aware of the importance and effect of the open spaces on the quality of l ife and have given the City's reserves, parks, and 1-24 2013 CITY OF RANCHOS PALOS VERDES t...~ INFRASTRUCTURE REPORT CARD trails a priority along the years. This is translated in Rancho Palos Verdes Coast Vision Plan that (1) established the development and maintenance of community parks and recreational areas as a top priority and (2) outlined new carefully planned projects to enhance the enjoyment of the beautiful coastline and the natural landscape of the peninsula. The current city document representing the parks system is the Parks Master Plan that was last revised in 1989. With the vision plan and the associated park developments in place, the update of the 1989 City's Parks Master Plan becomes essential. An updated Parks Master Plan will consolidate existing information, accumulate and incorporate related planning efforts, and map data to determine both the existing and desired level of service related to both passive and active recreation in the City. As part of the implementation of the Coast Vision Plan, the City has two new major park developments on its unfunded CIP plan: The Lower Point Vicente Park Improvement Project (13-acre of the lower portion of PVIC) and the Gateway Park Development (a 23-acre site within the City's Landslide Moratorium area). Other major projects are the improvement of Grandview Park and Lower Hesse Park. r / ~ Parks are maintained by outside vendors retained by the City under the sup~rvision of the Public Works Department. Other park activities and rentals are managed by the Recreation and Parks Department. // Figure 6.1: Robert E Ryan Community Park // Assessment of Parks / / The City parks were afsessed based on: 1.

' 1-27 SECTION 8: TRAILS A CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD 2013 The City of Rancho Palos Verdes began planning for a non-motor vehicle transportation circulation system for pedestrians, equestrians, and bicyclists, as early as the adoption ofthe City's General Plan in 1975. In the early years after the City's formation, it was recognized that trails are an integral part of the City's circulation system and play an important role in contributing to the successful interaction of residential, institutional, commercial, and recreational zoning, while encouraging recreational and fitness opportunities. The City's trails network system includes : • 101 Preserve trails about 29 miles in length. The Preserve trails are within the Palos Verdes Nature Preserve. The Palos Verdes Peninsula Land Conservancy (PVPLC) is responsible for maintenance and repair of existing unimproved trails in the Preserve while the City is responsible for the construction of new trails and maintenance of improved trails. Preserve trails are generally maintained by volunteer crews. • 16 currently operating Non-Preserve Trails, about 3 miles, witbin designated trail easements / throughout the City, managed and maintained by the City. , The trails are designated for specific users. They are either pedesJrian, cyclists, equestrians, a combination of any two, or multipurpose trails designated for the three types 6f users. / The City's current Trails Network Plan is identified by the 1993 Conceptual Trails Plan (CTP), and the 1996 / Conceptual Bikeways Plan (CBP). Additionally, the 2012 city council adopted the Preserve Trails Plan (PTP) that identifies the trails for the Palos Verdes Natu~ai Preserve, and the 2008 Coast Vision Plan, which is "a modern vision to unify the City's coast through,Clesign," providing a framework of connectivity of public amenities within and adjacent to the City's coa'stal zone, and identifying the route of the City's segment of the California Coastal Trail. The current traiiS network plan divides the City into 5 sections or sub regions, as depicted on the project area map showJI 1n Figure 7.1 below: / The City anticipates the updating"1nd consolidation of all of its existing trails plans and documents into a single, comprehensive Trails Master Plan (TMP) expected to be completed in 2014. At this time, the City / expects the TMP to be orgar::iized in a similar geographical categorization. The TMP will also include the City's segment of the Califorl}i{ Coastal Trail (9.5 miles) that extends the entire length of the City's coastline between the boundary lines of the City of Palos Verdes Estates and the City of Los Angeles. 1-28 2013 • l ( -~Ao;iaff r:::::l a., "'""'"rv CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD Clpln ~t<I Plen,.,.• Pu>pirbO •Pa•h -GollCCo.111161 ... •'iii""lllliiC====5·~ .. Figure 7.1: Rancho Palos Verdes Trails Master Plan Project Area Assessment of Trails ' The trails network in the City is mainly comprised of natural trails, and the implementation of any new trails will strictly preserve the existing ecosystem. As such, physical condition is not an evaluation factor. The assessment of the trails was based on: 1. The available access points and trail markers/signage 2. Available parking, 3. Connectivity 4. Maintenance All trails within the City are accessible and are provided with adequate trail markers identifying the trail name, direction arrow, and designated trail uses. Trails also have signage indicating the direction of approved trails which help users recognize app'roved and unapproved trails. New signs have recently been installed at preserve trail heads explaini,ng the preserve rules . All trails have designat,~d public parking areas either at trail heads, at public parks , or street parking . Although currently sufficient, the noticed recent increase in the number of trail users is signaling the need for more public parking spaces. Recent efforts to link the Preserve and Non-Preserve trails has been tremendous and has improved the connectivity of the City's trail system. Connectivity with the trails in neighboring cities in the peninsula is being studied/implemented too. Trails are well maintained . Vegetation clearance and weed abatement are performed regularly to ensure easy and safe access and use. 23 1 SA 1-29 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD Figure 7.2: North Spur Trallhead at Alta Vicente Reserve / ; Final Grade / The Overall Grade for the trails is A Investment Needs / 2013 Trails maintenance provides for erosion control, vegetation clearance and weed abatement. Preserve trails are generally maihtained by volunteer crews managed p{PVPLC. Non-Preserve Trails are maintained by the City. Expenditure for the maintenance of Non-Preser;ve trails is not available as a separate item. It is included in the overall expenditure for parks, trails, and O{}en spaces which is about $1.3SM (FY13/14 Budget) mostly from General Funds.

The CIP plan includes the construction of the Crystal (Preserve) Trail (.12 mile) in the Forrestal Reserve. It also includes the following projects for the Non-Preserve Trails: (1) the Preliminary Planning, Design, and construction for the Bronco, Martingale, and Grayslake Trails, (2) the design and construction of the Salvation Army Trail Improvement Project, (3) The Sunnyside Segment Trail connection, and (4) the construction of trailheads at key entrances to the existing City trail system along with overlooks and vista points within the Vision Plan project area. These project will contribute to the completion of the City's Trails Network Plan and will improve the connectivity of the trails, the non-preserve trails, in particular. Allocation of investments will be required to maintain the current "A" grade of the trails. It was noticed that the currently available plans do not provide enough information oa;rthe non-existing trails in the Trails Network Plan. These non-existing trails, when constructed, will impr9v~ the connectivity of the trail system . These trails will be identified in the comprehensive Trails Master .Plan. Thus a comprehensive Trails Master Plan will be required to calculate the required investmel)t' needs for the Infrastructure / Management Program (IMP). Recommendations / 1.

Perform a Park1i1g Assessment Study for the trails system and provide solutions for the anticipated fufure increase in the need for public parking, particularly adjacent to the Preserve. This may include designating new parking areas or diverting trail users to less -used access points. 3. Perform a Visitor Survey/Study to find out the number of current trail users, the type of use (hike, bike, equestrian), and the expected increase in the number of visitors. Such a study will guide in planning future projects, their order of priority, and the need for new regulations to prevent any unintended consequences that may arise from the increase in the number of users. 4.

As a result, the City is more vulnerable to flooding from nearby canyons that carry runoff during rainstorms. To protect property and loss of life, the City's storm drain system has been carefully designed to capture the maximum amount of storm water through numerous inlets, including the newly constructed Mccarrell Canyon Storm Drain inlet shown below in Figure 8.1: / / Figure 8.1: Mccarrell Canyon Storm Drain Inlet North ot V D South / Due to the City's hilly terrain, the City's drainage system utilizes the natural landscape of the City to the extent possible, as underground drains discharge water into adjacent canyons and creeks, or carry it to man-made discharge structures. The City's storm water"~ltimately discharges into the ocean, in one of eight natural or man-made discharge points (see Figure 3.2). As a result of utilizing the City's natural landscape, however, / City staff is faced with challenges of /having to maintain the City's aesthetic quality while preventing debris accumulation from clogging drainJnlets. / Assessment of Storm water:' system / / / As mentioned previously, the City has a diverse, hilly terrain. The terrain varies from elevations at sea level to over 1,400 feet above sea level. Due to this diverse topography, the City's storm drain system is divided up into six separate drainage sub-basins, based on the natural characteristics of the terrain and the natural direction of runoff flows for the areas. The drainage sub-basins include the following: Drainage Area Los Angeles Drainage Area Ocean South Drainage Area Ocean West Drainage Area Palos Verdes Estates West Drainage Area Palos Verdes Estates North Drainage Area Rolling Hills Estates Drainage Area Total 27 I SA Area (ac) 2820 3330 710 1100 450 500 8910 1-33 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD 2013 Of the sub-basins, the Ocean South Drainage Sub -basin is the largest, consisting of over 3,300 acres and nearly the majority of the City's coastline. The City's landslide area is also located within the Ocean South Drainage Sub-basin. Palos Verdes Drive South (PVDS) is the major arterial street that transverses the Ocean South Drainage Sub-basin. The Ocean South Drainage Sub-basin is also the only area of that contains undeveloped land (that is not marked as reserve land), including the Portuguese Bend area north of PVDS. Every other drainage sub-basin is nearly fully developed with a significant drainage infrastructure network. With regard to man-made infrastructure, the City's storm drain system consists of inlets, pipes, manholes, and discharge structures. Storm drain pipes consist of reinforced concrete pipe (RCP), and corrugated metal pipe (CMP). Overall, the condition and capacity of the City's storm drain infrastructure is consistent throughout each drainage sub-basin. According to the City's records, there are over 4.6 miles of storm drain lines, 82 culverts, along with a multitude of inlets, catch basins, and manholes. A significant portion of the City's storm drain infrastructure lies within the Ocean South Drainage Area, including a number of culverts that cross PVDS. Since a number of these culverts are also located within the City's landslide area, the culverts are vulnerable to damage from severe landslides that result from heavy storms . Tile damage can also be compounded when the culverts become clogged with natural debris from the surrounding landscape which gets washed down during rainstorm periods . This could result in flooding which increases the potential for significant landslide activity to occur. To prevent flooding, the City's goal is to ensure that the storm drain pipe network drains stormwater away from developed areas and into one of eight outlets, as shown in Figure 8.2 below: , Figure 8.2: Outlet Structure to Ocean in Ocean West Drainage Area As part of the City's goal to prevent flooding, the City is continually in the process of maintaining its existing infrastructure and improving it by adding additional infrastructure. Maintenance typically includes repairing and/or replacing damaged pipe, removing debris, and modifying existing. New improvements vary from small residential storm drains to large, multi-million dollar projects such as the under-construction San-Ramon Canyon Project just north of PVDS. After reviewing several documents related to its storm water infrastructure, and visiting several locations, including those in Figure 8.1 and Figure 8.2, the City 's storm water system was evaluated on following three criteria: 1. The capacity of storm water infrastructure as it relates to flood prevention 2. The structural condition of storm water infrastructure as it relates to operation and maintenance 1-34 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD 3. The environmental sustainability of storm water infrastructure as it relates to preserving the natural landscape and wildlife when operating, maintaining, and improving stormwater infrastructure. Final Grade After looking at the three grading criteria categories, it was determined that the City had good capacity to transmit storm water flows, average structural condition with appropriate operation and maintenance, and exceptional environmental sustainability. The weight of these three criteria was then weighed as to the overall level of importance of the system. Overall, the City's storm water system earned a grade of C. Recommendations Based on the assessment and grade of the City's storm water infrastructure, we recommend the following actions: • • • • • • Maintain a strong CIP program / A strong CIP program adds new infrastructure and also replaces existitlg failing infrastructure. Renew Rates / The City currently charges a fee to help fund its storm water ,system. This fee will expire at the end of fiscal year 15-16. As a result of aging infrastructure and,rising construction costs, the City and i.ts citizens will benefit from a more substantial storm wat~ budget resulting from renewal of the rates. Utilize Natural Drainage Patterns , Thus far, the City has done a terrific job of utilizing natural drainage canyons and channels as opposed to pipes and concrete channels. The City wou~d/benefit by continued use of natural landscapes to keep the costs associated with constructing J1ew facilities low, when possible. / Install debris reduction methods / Debris reduction methods may includef the use of grouted rip-rap, where possible, in the place of loose rock and gravel. / Maintain proper maintenancefcreaning Strong maintenance ensure~ properly working storm drains and the protection of property. Inspect 100% of known Storm Drain System / Sources / / / This report summary for the City's storm water system has been has been determined as a result of the following sources of data: • 2004 Master Plan Update • CIP Priority Lists • GIS Maps • Current GIS Spreadsheet Data • Meetings with City Staff • Field Analysis 29 I SA 1-35 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD SECTION 10: CITYWIDE SANITARY SEWER SYSTEM 0 2013 The City's landscape consists of developed land to the extent practical, and the majority of the development in the City consists of single family residential homes . This results in the need for an extensive sewer system that has the capacity to properly transmit wastewater flows. Due to the City's hilly terrain, this results in the need for a carefully designed sewer system that utilizes the natural landscape of the City to the extent practical, in order to avoid additional infrastructure which can add to operation and maintenance costs and lower the reliability of the system during power outages or equipment malfunctions.

With regard to its sanitary sewer infrastructure, there are over 150 miles of sewer pipelines, 17 litystations, 44 grinder pumps, and 3,707 manholes. Sewer pipes consist primarily of vitrified clay pipe (VCP~ with some plastic pipe, along with a few other materials. Due to the age of the City's sewer system, thetfllajority of its pipe (VCP) was installed without gaskets, as the prevailing theory was that additional grounawater that flowed into the pipes was good for cleaning and flushing of the pipes. 1-36 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD Figure 9.2: Calle Entradero Sewer Station / As part of the City's goal to maintain a properly working sewer system and ,t6 protect the public, the City is continually in the process of maintaining its existing infrastructure and improving it by adding additional infrastructure. The LA County Department of Public Woks provides me}intenance for the City's sewer system . Maintenance typically includes repairing damaged pipe, repairing lift stations, removing debris from pipes, and repairing manholes. New improvements vary from pipeline/eplacement to lift station replacement. After reviewing several documents related to its sewer infrastructure, the City's sewer system was evaluated on following three criteria: , / 1. The capacity of sewer infrastructure as it relates to transmission of wastewater flows (both gravity pipes and pressurized force mains). " 2. The structural condition of sewer intrastructure as it relates to operation and maintenance. 3. The environmental sustainability'of sewer infrastructure as it relates to ensuring sanitary conditions and an aesthetic City landsccipe. Final Grade / After looking at the three grading criteria categories, it was determined that the City had good capacity to transmit wastewater flo,w~ (both gravity and pressurized force mains), below average structural condition with appropriate operation and maintenance, and a good safety/sanitary protection. The weight of these three criteria was then weighed as to the overall level of importance of the system. Overall, the City's wastewater system earned a grade of a D. Recommendations Based on the assessment and grade of the City 's sewer infrastructure, we recommend the following actions : • Maintain a strong CIP program A strong CIP program adds new infrastructure and also replaces existing failing infrastructure. • Establish a sewer user fee rate The County currently charges a fee to help fund maintenance of the sanitary sewer system.

The District development is located in the heart of the landslide area and experiences a slow but continuous land movement. As a result, the District requires a special kind of sewer system that can maximize reliability while minimizing maintenance due to ground movement. The District also requires a system that fits its hilly terrain. Figure 10.1 below shows the Abalone Cove landscape: Figure 10 .1: Abalone Cove/Portuguese Bend Reserv~, ' Assessment of Abalone Cove Sewer System / / / / / / As mentioned previously, the District, as well as the City overall, has a diverse, hilly terrain. The terrain varies , from elevations at sea level to over 1,,400 feet above sea level. As a result, the District has to utilize a combination of gravity pipes, grinder' pumps, low-pressure sewer mains, lift stations, and high pressurized force mains. According to the 20.p~{ Master Plan, the District's system was installed in 2001 to replace septic systems in landslide areas. There are 130 manholes, 1 diversion structure, approximately 19,000 linear feet of gravity pipeline, 19,615 Jinear feet of low pressure pipe, and 2,505 linear feet of force main. Overall, there are 44 grinder pumps in the District, with 41 of them serving single family homes and 3 duplex grinder pumps serving two or more residences. There are 4 lift stations serving the District, one of which is the Abalone Cove Shoreline Park Lift Station shown in Figure 10.2 below: 33 1 SA 1-39 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD Figure 10.2: Abalone Cove Shoreline Park Sewer Lift Station ; 2013 Since the District is prone to landslide, the City is continually in the process of maintaining its existing infrastructure and improving it by adding additional infrastructure. Mainten'ance typically includes repairing damaged pipe, repairing lift stations, grinder pumps, removing debris from pipes, and repairing manholes. New improvements vary from pipeline replacement to lift statio,n ~eplacement. With the Abalone Cove Assessment District, this is all the more important, due to the presence of multiple grinder pumps and low pressure mains that use galvanized transmission lines, as welJ ls' the potential for landslide.

Recommendations Based on the assessment and grade of the City's sewer infrastructure, we recommend the following actions: • Maintain a strong CIP program A strong CIP program adds new infrastructure and also replaces existing failing infrastructure. • Increase Rates The City currently charges a fee from District properties to help fund the District's sanitary sewer SA 1-40 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD system. Even though the City subsidizes part of the maintenance cost, the budget is not sufficient for required maintenance and capital improvements. As a result of high maintenance and replacement costs due to landslide activity, the District and its citizens will benefit from a more substantial sanitary sewer budget resulting from an increased rate. • Maintain proper maintenance Strong maintenance ensures properly working lift stations, sewer mains, and the protection of property and the public.

Due to the demographics of the City, local streets comprise the majority of the City's roadways at approximately 75% of the overall length or 106 miles. All of the City's roadways consist of asphalt-concrete (AC), with over 23 million square feet of AC pavement. In addition to the road network, the City also maintains traffic signals, safety lights, and flashers . The City's right of way network serves both motorists as well as bicyclists and pedestrians with nearly all major arterials consisting of a sidewalk and bike lanes. Figure 11.1 below provides a sample of the condition of the City's streets. / / Figure 11.1: Crest Rd west of Crenshaw Blvd lopi<ing southwest I In 2009, the City hired a consultant to prepare a Pavement Management System (PMS) report that provided a summary, inventory, and breakdown of the condition of the City's streets. The 2009 PMS was prepared as a means to guide planning efforts to maintain the City's large capital investment in streets. The main function of the PMS lies in the implementation of capital improvements such that every dollar spent is maximized towards extending the lifespap -o'f the street network. The 2013 PMS update is currently being prepared and is expected to be completed by March 2014. / / Assessment of City Right of Way and Traffic Devices Due to the City's hilly terrain, major arterials are not arranged in a typical North/South grid-like manner, but rather change direction as they traverse the City's landscape. Figure 11.2 below illustrates this. SA 1-42 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD Figure 11.2: Hawthorne Blvd looking northwest Oftentimes, the City's major arterials do not provide direct access to destinations. Th~re are also no freeways or highways located in the City. However, travel access restrictions are offset by,, the natural beauty of the City and the man-made landscape improvements along the City's streets, and .the City is well known for its accommodating environment to all commuters, including cyclists, equestri~( and pedestrians. Nearly all of the City's major arterials provide bike lanes for cyclists. The City's bi~e lanes are categorized into four different classes of bike lanes, as classified by the City's Conceptual Bi~eways Plan (Plan), adopted in January of 1990 and revised in October of 1996. The Plan classifies bikeways as either Class I, Class I/Off-Road, Class II, or Class Ill. The Plan's purpose is to identify the bikeway'J' bpportunities with the community and to implement new bikeways into development projects and into the City's public trails network. One major factor that makes the City's streets so appe9lrhg to both motorists and cyclists is the condition of the pavement, not only on major arterials but throµghout the City's streets as whole. The 2009 Pavement / Management System (PMS) revealed that the Cit~'s streets received an overall score of 84.5 on the Pavement Condition Index (PCI) and 95.3 on the Structurjl't Index (SI), while arterials received a score of 76.8 on the PCI index and 90.8 on the SI index. The PCI ancfSI indexes focus on different aspects of pavement conditions. Residential streets received a score of 87.6 on the PCI Index and a score of 97.1 on the SI index. The 2013 / PMS update revealed that the City's s~reets received an overall score of 82 on the PCI index. PCls greater than 86 are considered to be "very goo~,u/and Sis greater than 90 are considered to be "good".

A recent Traffic Study Report conducted in 2011-2012 revealed that the current traffic conditions in certain intersections of Palos Verdes Drive South and Hawthorne Boulevard resulted in a LOS ranging from A to F, with F being a low level of service with traffic delays. The Traffic Study Report was prepared mainly to identify traffic impacts associated with a development project in the Abalone Cove are known as the Annenberg Project . Despite the low LOS associated with certain intersections, the City does look for new ways to improve traffic conditions , and overall traffic conditions are good throughout the City . With regard to pedestrian traffic, the City does have an annual sidewalk maintenance program, with an annual budget of $140,000 . The City routinely looks for ways to improve sidewalk conditions throughout the City, and sidewalk conditions were noted to be in great condition throughout the City . After reviewing several documents related to the City's right of way and traffic devices, the City's right of way and traffic devices were evaluated on following three criteria: / 1. The capacity of infrastructure as it relates to accommodating vehicula~, bicycle, equestrian, and pedestrian traffic flows 2. The structural condition of infrastructure as it relates to drive-ability, fide -ability, walk-ability, safety, / and also as it relates to operation and maintenance costs and efforts. 3. The environmental condition of infrastructure as it relates to promoting recreation, an aesthetic environment, and preserving nature. / Final Grade / After looking at the three grading criteria categories, it was determined that the City had good capacity to accommodate traffic flows, good structural cqnditions of pavement and sidewalk, and excellent environmental conditions. The weight of these three criteria was then weighed as to the overall level of importance of the system .

Overall, these landslides move southerly towards the ocean into the Abalone Cove, Sacred Cove, and Portuguese Bend shorelines. Approximately 1,000 acres, or 12% ofthe City's 13.6 square mile limits, are affected by landslide. The landslide affects not only surface streets and buildings, but also other infrastructure as well, including below grade utilities. Figure 12.1 below shows part of the City's landscape that is located within the landslide region: / / , Figure 12.1: Palos Verdes Drive South along Landslij:le Area , / Assessment of the Landslide and Landslide"lnfrastructure , There are over a dozen landslides that ma'ke up what is known as the City's landslide area along Palos Verdes / Drive South. The three main landslides in the City are the Abalone Cove, Portuguese Bend, and Klondike / Canyon Landslides. The landslides ;:ire caused primarily by groundwater which decreases the strength of clays and adds additional weight to ~ubsurface soils. Rainfall is the primary contributor to groundwater. The City has three main drainage ba;;in's within the landslide regions that collect rainwater and allow it to percolate to the soils below. The7e/ drainage basins include the Altamira Canyon Drainage Basin, the Portuguese Canyon/Paintbrush C~Ayon Drainage Basin, and the Klondike Canyon Drainage Basin. It is estimated that 50- 75% of storm water infiltrates the canyons to become groundwater, primarily through fractures and expansive soils. Although the City has established drainage facilities within these canyons, the landslide movement causes damage to drainage facilities which enables more storm water to enter the surface below. Figure 12.1 shows a damaged half corrugated pipe system along Palos Verdes Drive South resulting from continuous landslide movement: 1-46 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD Figure 12.2: Landslide Damage to Palos Verdes Drive South ,/ To combat infiltrating storm water and landslide movements, the City has established mitigation infrastructure and improvements as part of efforts to slow the rate of tlfe' landslides and to minimize the likelihood of catastrophic landslide movements. This mitigation infrastructure consists of, grading, and dewatering wells in addition to drainage and sewer systems. For th[s ;ection of the report, only the, grading, and dewatering wells were evaluated. The grading performed by/the City in 1986 and recently in 2010 has resulted in significant benefits for the City. Also, the City's de~tering wells (in addition to other wells not ·' owned by the City) help extract groundwater which enables subsurface ground movement. Overall, it appears that the mitigation efforts and infrastructure are''effective in slowing subsurface land movement and ' preventing storm water from collecting/ponding. / After reviewing several documents related tqAhe City's landslide mitigation infrastructure, the following three categories were evaluated: / 1. The capacity of the infrastruc~u(e to prevent or slow subsurface land movement 2. The condition of the infrastJucture as it relates to operation and maintenance. 3. The environmental imp_atts as it relates to maintaining dwellings, landscapes, and utilities, and protecting the public ffom harm. / Final Grade / After looking at the three grading criteria categories, it was determined that although the condition and environmental impacts of the infrastructure (i.e. grading/drainage ) was measurable , and although the dewatering wells extract a large amount of groundwater, the infrastructure is inadequate during years of high rainfall, leaving the City's streets and building vulnerable to landslide damage. Overall, the City's landslide mitigation infrastructure earned a grade of A. Recommendations Based on the assessment and grade of the City's sewer infrastructure, we recommend the following actions: • • Maintain a strong CIP program A strong CIP program adds new infrastructure and also replaces existing failing infrastructure. Continue to seek and obtain Funding Sources .. 1-47 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD 2013 The City's existing funding sources, although adequate for routine maintenance, may need to be supplemented to implement larger improvement projects, especially after a landslide emergency. • Maintain a strong maintenance program Strong maintenance ensures properly working mechanical infrastructure, and also corrects eroded grading improvements. • Continue to Work Together with other agencies A portion of dewatering wells located in the City are not owned by the City. Thus, the City would benefit from a continued and strong alliance with all owners of landslide mitigation infrastructure. • Groundwater sources in neighboring cities should be investigated and minimize, if possible Sources This report summary and the grade assigned for the City's landslide mitigation infrastructure system has been has been determined as a result of the following sources of data: ,.- / • 2012 Abalone Cove , Portuguese Bend, and Klondike Canyon Landftli'des: Landslide Workshop Presentation • Discussions with City Staff / / / / / / / / / / SA / ; " / 1-48 2013 CITY OF RANCHOS PALOS VERDES INFRASTRUCTURE REPORT CARD SECTION 14: ACKNOWLEDGEMENTS City of Rancho Palos Verdes: • Siamak Motahari Public Buildings, Parks, Trails • Bindu Vaish Public Buildings, Parks, Trails • Ron Dragoo Storm Water, Sewer, Abalone Cove Sewer, Palos Verdes Drive South Landslide • Andy Winje Storm Water, Sewer, Abalone Cove Sewer, Palos Verdes Drive South Landsl~9e • Nicole Jules Right of Way • Ara Mihranian Trails SA Associates: • Shahnawaz Ahmad President, Project Manager • Ruba Qaqish Public Buildings, Parks, and Trails / • Phillip West / / / / ; / I' / / Storm Water, Sewer, Abakine Cove Sewer, and Palos Verdes Drive South Landslide / / / / 43 I SA 1-49 CIJ w 0 O! w > CIJ 9 ~ u.O o::C .... o oZ: w<( ~~ 1 I 1-50
