Stephens (page C-1) BACKGROUND AND DISCUSSION: The City Council approved the update to the Portuguese Bend Feasibility Study at its August 7, 2018, meeting. The City Council Subcommittee for the Landslide Feasibility Study Update reviewed and edited the Request for Proposals (RFP) document for Engineering Analysis, Evaluation, and Design for improvements in the Portuguese Bend 1 Landslide to include Drainage and Dewatering (hydro-augers). The RFP document (Attachment B) was released October 11, 2018. Several consultants were directly contacted by Staff and the RFP was published on the City's website in an extended effort to solicit qualified consultants to submit proposals for the proposed project. The RFP document asked consultants to provide proposals to the City for their services including: • Perform a hydrology study of the watershed including specific hydrologic and engineering analysis of the watershed to identify as to where, what quantity, how, and to what extent the stormwater runs off and/or infiltrates into the landslide and becomes part of the groundwater in the Portuguese Bend Landslide Complex; • Perform engineering analysis, evaluation, and designs for the lower portion of the Portuguese Bend Landslide that would convey the drainage runoff to the ocean directly; • Design groundwater extraction horizontal drains (hydro-augers) for the lower area of the landslide, including a cost benefit analysis for the hydro-augers and any alternatives; and, • Analyze and design repair plans if sealing fractures in the landslide area between Palos Verdes Drive South and Burma Road is determined to be needed. Two proposals were received by the November 12, 2018, submittal deadline. Both proposals were reviewed and Daniel B. Stephens (Attachment C) was determined to be the most qualified for the project and required process, including public input and reviews. Following this determination, Staff entered into negotiations for the fee and to further refine and narrow the final scope of work for the project. If this Professional Services Agreement (Attachment A) is approved, the work will only include: (1) the design of the drainage system at the bottom portion of the landslide located to the south of Burma Road; (2) the design of any necessary fracture infill in this area; (3) the design of the underground hydro-augers at the bottom of the slide; and, (4) the hydrology/hydraulic analysis in the canyons. Any design work to potentially line any or all of the canyons north of Burma Road is not included in this proposal. Environmental review work associated with any part of the designs that will be developed will be undertaken following City Council approval of the designs. As the Consultant develops engineering designs, they will meet with Staff and applicable State/Federal agencies as well as the Palos Verdes Peninsula Land Conservancy (PVPLC) and the City Council Subcommittee to review those designs. A community outreach meeting will follow to solicit comments on the initial conceptual design of mitigation efforts, and a 30-day public comment period will be provided to review proposed design concepts and siting of proposed designed improvements. Modifications to the design and locations, if needed, will be completed prior to proceeding with the ensuing design of the Portuguese Bend Landslide Mitigation Project. A final public outreach meeting will be conducted and the review and plan update process repeated prior to bringing the final design plans to the City Council for review and approval. 2 Based on their clear understanding of project constraints, local geology, movement and general characteristics of the landslide, along with the results of the negotiations associated with project scope and cost, Staff is recommending approval of the Professional Services Agreement with Daniel B. Stephens & Associates, Inc. to perform design services for this project. ALTERNATIVES: In addition to the Staff recommendations, the following alternative action is available for the City Council's consideration: 1. Discuss and provide recommendations on other options that may be appropriate. 3 CONTRACT SERVICES AGREEMENT By and Between CITY OF RANCHO PALOS VERDES and DANIEL B.

A severability of interests provision must apply for all additional insureds ensuring that Consultant's insurance shall apply separately to each insured against whom claim is made or suit is brought, except with respect to the insurer's limits of liability. The policy(ies) shall not contain any cross-liability exclusions. (m) Pass through clause. Consultant agrees to ensure that its subConsultants, subcontractors, and any other party involved with the project who is brought onto or involved in the project by Consultant, provide the same minimum insurance coverage and endorsements required of Consultant. Consultant agrees to monitor and review all such coverage and assumes all responsibility for ensuring that such coverage is provided in conformity with the requirements of this section. Consultant agrees that upon request, all agreements with Consultants, subcontractors, and others engaged in the project will be submitted to City for review. (n) Agency's right to revise specifications. The City reserves the right at any time during the term of the contract to change the amounts and types of insurance required by giving the Consultant ninety (90) days advance written notice of such change.

City retains the right, but has no obligation, to represent Consultant or be present at any deposition, hearing or similar proceeding. Consultant agrees to cooperate fully with City and to provide City with the opportunity to review any response to discovery requests provided by Consultant. However, this right to review any such response does not imply or mean the right by City to control, direct, or rewrite said response. ARTICLE 7. ENFORCEMENT OF AGREEMENT AND TERMINATION 7.1 California Law. This Agreement shall be interpreted, construed and governed both as to validity and to performance of the parties in accordance with the laws of the State of California. Legal actions concerning any dispute, claim or matter arising out of or in relation to this Agreement shall be instituted in the Superior Court of the County of Los Angeles, State of California, or any other appropriate court in such county, and Consultant covenants and agrees to submit to the personal jurisdiction of such court in the event of such action. In the event of litigation in a U.S. District Court, venue shall lie exclusively in the Central District of California, in the County of Los Angeles, State of California. 7.2 Disputes; Default. In the event that Consultant is in default under the terms of this Agreement, the City shall not have any obligation or duty to continue compensating Consultant for any work performed after the date of default. Instead, the City may give notice to Consultant of the default and the reasons for the default. The notice shall include the timeframe in which Consultant may cure the default. This timeframe is presumptively thirty (30) days, but may be extended, though not reduced, if circumstances warrant. During the period of time that Consultant is in default, the City shall hold all invoices and shall, when the default is cured, proceed with payment on the invoices. In the alternative, the City may, in its sole discretion, elect to pay some or all of the outstanding invoices during the period of default. If Consultant does not cure the default, the City may take necessary steps to terminate this Agreement under this Article. Any failure on the part of the City to give notice of the Consultant's default shall not be deemed to result in a waiver of the City's legal rights or any rights arising out of any provision of this Agreement. 01203.0006/524815.6 15 A-16 7.3 Retention of Funds. Consultant hereby authorizes City to deduct from any amount payable to Consultant (whether or not arising out of this Agreement) (i) any amounts the payment of which may be in dispute hereunder or which are necessary to compensate City for any losses, costs, liabilities, or damages suffered by City, and (ii) all amounts for which City may be liable to third parties, by reason of Consultant's acts or omissions in performing or failing to perform Consultant's obligation under this Agreement. In the event that any claim is made by a third party, the amount or validity of which is disputed by Consultant, or any indebtedness shall exist which shall appear to be the basis for a claim of lien, City may withhold from any payment due, without liability for interest because of such withholding, an amount sufficient to cover such claim. The failure of City to exercise such right to deduct or to withhold shall not, however, affect the obligations of the Consultant to insure, indemnify, and protect City as elsewhere provided herein. 7.4 Waiver. Waiver by any party to this Agreement of any term, condition, or covenant of this Agreement shall not constitute a waiver of any other term, condition, or covenant. Waiver by any party of any breach of the provisions of this Agreement shall not constitute a waiver of any other provision or a waiver of any subsequent breach or violation of any provision of this Agreement. Acceptance by City of any work or services by Consultant shall not constitute a waiver of any of the provisions of this Agreement. No delay or omission in the exercise of any right or remedy by a non-defaulting party on any default shall impair such right or remedy or be construed as a waiver. Any waiver by either party of any default must be in writing and shall not be a waiver of any other default concerning the same or any other provision of this Agreement. 7.5 Rights and Remedies are Cumulative. Except with respect to rights and remedies expressly declared to be exclusive in this Agreement, the rights and remedies of the parties are cumulative and the exercise by either party of one or more of such rights or remedies shall not preclude the exercise by it, at the same or different times, of any other rights or remedies for the same default or any other default by the other party. 7.6 Legal Action. In addition to any other rights or remedies, either party may take legal action, in law or in equity, to cure, correct or remedy any default, to recover damages for any default, to compel specific performance of this Agreement, to obtain declaratory or injunctive relief, or to obtain any other remedy consistent with the purposes of this Agreement. Notwithstanding any contrary provision herein, Consultant shall file a statutory claim pursuant to Government Code Sections 905 et seq. and 910 et seq., in order to pursue a legal action under this Agreement. 7.7 Liquidated Damages. Since the determination of actual damages for any delay in performance of this Agreement would be extremely difficult or impractical to determine in the event of a breach of 01203.0006/524815.6 16 A-17 this Agreement, the Contractor and its sureties shall be liable for and shall pay to the City the sum of zero ($0.00) as liquidated damages for each working day of delay in the performance of any service required hereunder. The City may withhold from any monies payable on account of services performed by the Contractor any accrued liquidated damages. 7.8 Termination Prior to Expiration of Term. This Section shall govern any termination of this Contract except as specifically provided in the following Section for termination for cause. The City reserves the right to terminate this Contract at any time, with or without cause, upon thirty (30) days' written notice to Consultant, except that where termination is due to the fault of the Consultant, the period of notice may be such shorter time as may be determined by the Contract Officer. In addition, the Consultant reserves the right to terminate this Contract at any time, with or without cause, upon sixty (60) days' written notice to City, except that where termination is due to the fault of the City, the period of notice may be such shorter time as the Consultant may determine. Upon receipt of any notice of termination, Consultant shall immediately cease all services hereunder except such as may be specifically approved by the Contract Officer. Except where the Consultant has initiated termination, the Consultant shall be entitled to compensation for all services rendered prior to the effective date of the notice of termination and for any services authorized by the Contract Officer thereafter in accordance with the Schedule of Compensation or such as may be approved by the Contract Officer, except as provided in Section 7.3. In the event the Consultant has initiated termination, the Consultant shall be entitled to compensation only for the reasonable value of the work product actually produced hereunder. In the event of termination without cause pursuant to this Section, the terminating party need not provide the non-terminating party with the opportunity to cure pursuant to Section 7.2. 7.9 Termination for Default of Consultant. If termination is due to the failure of the Consultant to fulfill its obligations under this Agreement, City may, after compliance with the provisions of Section 7.2, take over the work and prosecute the same to completion by contract or otherwise, and the Consultant shall be liable to the extent that the total cost for completion of the services required hereunder exceeds the compensation herein stipulated (provided that the City shall use reasonable efforts to mitigate such damages), and City may withhold any payments to the Consultant for the purpose of set-off or partial payment of the amounts owed the City as previously stated. 7.10 Attorneys' Fees. If either party to this Agreement is required to initiate or defend or made a party to any action or proceeding in any way connected with this Agreement, the prevailing party in such action or proceeding, in addition to any other relief which may be granted, whether legal or equitable, shall be entitled to reasonable attorney's fees. Attorney's fees shall include attorney's fees on any appeal, and in addition a party entitled to attorney's fees shall be entitled to all other reasonable costs for investigating such action, taking depositions and discovery and all other necessary costs the court allows which are incurred in such litigation. All such fees shall be deemed to have accrued on commencement of such action and shall be enforceable whether or not such action is prosecuted to judgment. 01203.0006/524815.6 17 A-18 ARTICLE 8. CITY OFFICERS AND EMPLOYEES: NON-DISCRIMINATION 8.1 Non-liability of City Officers and Employees. No officer or employee of the City shall be personally liable to the Consultant, or any successor in interest, in the event of any default or breach by the City or for any amount which may become due to the Consultant or to its successor, or for breach of any obligation of the terms of this Agreement. 8.2 Conflict of Interest. Consultant covenants that neither it, nor any officer or principal of its firm, has or shall acquire any interest, directly or indirectly, which would conflict in any manner with the interests of City or which would in any way hinder Consultant's performance of services under this Agreement. Consultant further covenants that in the performance of this Agreement, no person having any such interest shall be employed by it as an officer, employee, agent or subcontractor without the express written consent of the Contract Officer.

Consultant will perform the following Services: Consultant will complete a hydrology study of the watershed, including a specific hydrologic information and engineering analysis of the Canyons to identify where, what quantity, how, and to what extent the stormwater infiltrates into the groundwater in the Portuguese Bend Landslide Complex. Based on a the hydrology study and resultant water balance analysis, Consultant will develop the engineering analysis required to evaluate, and provide a design for, the lower portion of the Portuguese Bend Landslide in order to convey the drainage runoff to the ocean directly, and Consultant will provide the design and placement location to bring about the quantity of groundwater extraction through horizontal drains (hydro- augers) for the lower area of the landslide to achieve the design goals. Summary of the Tasks: • Review existing records and field inventory with design team. • Perform Hydrology analysis and the water balance for the entire watershed. • Determine areas that require fracture in-filling located south of Burma Road. • Design of the Hydro-Augers, determine their placement, drainage design and perform a cost-benefit analysis specific to proposed improvements. • Provide utility identification and coordination for proposed construction activities. • Develop construction plan sheets based on engineering design. • Develop the Engineer's Estimate and estimated project cost and construction schedule. • Develop the Technical Specifications and applicable Special Provisions. • Develop the Bid document package. • Attend monthly meetings with regulatory agency interaction and answer questions or requests for information(RFI) through the project bidding process). • Develop all final project deliverables and as-built drawings. • Perform all project Surveying. • Provide updates for the City's website specific to design services and public outreach meetings. • Attend meetings including project kickoff meeting, three City Council Meetings, two public outreach meetings. Services by Task A. TASK A: Project kick-off meeting 1. Key members of Consultant's project team will meet with City staff to outline the drainage and dewatering design project in detail before major tasks commence. Consultant will present its proposed WBS and project schedule along with a summary of the major tasks and its approach to each task and subtask. The lines of communication between team members, the 01203.0006/524815.6 A-4 A-25 City and community, and other stakeholders will also be discussed. Data needs from the City and major deliverables will be outlined in order to achieve a common understanding regarding the overall project as well as proposed methodologies, engineering technologies, and dewatering/ drainage and landslide mitigation goals. B. TASK B: Review Existing Records/Field Inventory 1. Consultant has already comprehensively reviewed the key reports in the City's document library during document compilation and review during the Portuguese Bend Feasibility Study Update ("FS Update", found here: http://www.rpvca.gov/documentcenter/view/12275) preparation. The key documents and data will be further incorporated into new work as needed in Consultant's planning and design tasks to be completed for the proposed scope of work. Consultant will work with City staff to further identify any additional documents to add to the library as needed. C. TASK C: Develop Project Hydrology Analysis Consultant will collect critical field data in order to perform an accurate and meaningful Water Balance to support project design. Therefore, the Hydrologic Analysis will include field data collection (Task C 1) to prepare an optimized Water Balance to summarize available data and estimate the sources of groundwater in the Red Zone area (Task C2). The Hydrologic Analysis will focus on the Portuguese Canyon/Paint Brush Canyon Drainage Basin or subwatershed ("Hydrologic Analysis Area") as shown on the figure below.

Synoptic streamflow discharge survey. Following a wet-weather event, Consultant will collect streamflow discharge data at several locations along the Canyons. This data will be used to identify sections of the Canyons where streamflow may recharge to groundwater and to estimate groundwater recharge. If flow in the measured reach of the stream has decreased from upstream to downstream, the decrease may be attributed to streamflow recharging groundwater. This type of survey is commonly referred to as a "seepage run." Field methods will be consistent with U.S. Geological Survey (USGS) techniques and will utilize staff gauges and volumetric gauges (Rosenberry and LaBaugh, 2008). The timing of the utility of this task is contingent on a suitable wet-weather event occurring during the project period. 3. Surface water conveyance survey. Stormwater flowing through the Canyons is currently routed to the Pacific Ocean through an existing storm drain network constructed in the Red Zone area (figure shown on next page). The surface conveyances will be visually surveyed to evaluate their current location, condition, and current ability to transmit estimated peak streamflow. 4. Groundwater well inspection survey. Information provided by the City indicates that up to 20 dewatering wells have been constructed and installed within the Hydrologic Analysis Area during previous mitigation efforts. Except for four recent wells installed in 2016, no information could be located that documents the well construction details, purpose of each well (monitoring or dewatering), date of installation, well temporal monitoring data, or the current status of the well, and the FS Update recognized this limitation as a data gap that should be aggressively addressed moving forward. Consultant will perform a well inspection survey of wells in the Hydrologic Analysis Area, including, as appropriate, down-hole video surveys and measurement of depth-to-groundwater, wellhead elevation, well depth and diameter, and well screened interval. Consultant will also perform limited aquifer testing of existing wells (e.g., slug tests) as a basis for estimating hydraulic aquifer properties. 01203.0006/524815.6 A-7 A-28 5. Irrigation Practices Survey. Within the Hydrologic Analysis Area, landscape irrigation occurs within the Rolling Hills neighborhood and adjacent City neighborhoods as well as within the Palos Verdes Nature Preserve. Consultant will perform a visual field survey of landscape irrigation practices, including irrigated areas, landscape vegetation (e.g., turf versus ornamentals), irrigation system, and the presence or absence of overspray runoff to impervious surfaces that results in irrigation water flow to the stormwater system. The irrigation practices survey will serve as a basis for irrigation rate estimation for the water balance, described below. Site access for Rolling Hills will be obtained by City. E. TASK C2. Water Balance/Groundwater source assessment 1. Data collected under Task Cl, described above, will be used in conjunction with data collected from previous studies to develop an optimized Water Balance of the Hydrologic Analysis Area. Within the Hydrologic Analysis Area, a supplemental water balance will also be conducted for the area of greatest land movement within the Portuguese Landslide Complex ("Red Zone ") (figure below, see next page)to identify significant sources of groundwater recharge and support design of the dewatering system. 01203.0006/524815.6 A-8 A-29 - • rY` 1 C• ♦ p4 / Hydrologic s • 9 a• • .-I. , - Analysis Areal te ter. •,■ } . o_ 1 4 iii \it ..i._ii. . ilk •Al ` a • • • • • -F_ }co •r�o{+ t m on 1 y +.{ i Q - 4 i �-. 9 b r FYa y• r • • M t `"—"`�✓ J t l' ° • , A ram. / :100.0, ilb Ii, IC ° f" it a 1' � .ra« a 4 j ' , ti4 • • ► » . • Explanation j . ,_„,:r., f Rancho Palc V es 2'2°1': `tat: PorrugLesc CaTeovca,t 3r.sh Carryall Drainage Baser • Storm drain structure 0 GrindierPurrp Major canyon Aillik Storm drain hydro catchment ■ Limit Sbtian Situ bounden.. flow * Pump..Plant M Portuaue a Landslide Storm drain hydro low ✓ Sewer n,anholie 0 1,000 2.000 Feet Storm drain pipe III Sewer pipe Major i_lidis 01203.0006/524815.6 A-9 A-30 2. The Water Balance will consist of the following components: a. Aquifer characterization and groundwater flow assessment. Groundwater flow direction and volumetric flux will be estimated based on the areal extent, thickness, and other physical characteristics of the shallow aquifer underlying the Red Zone area and canyons. To support this analysis, a groundwater elevation map will be developed for the Hydrologic Analysis Area, and cross-sections presented in the FS Update Appendix C will be updated to project groundwater elevation throughout the upper Canyon areas. b. Groundwater data will be obtained from data collected under Task Cl, from previous studies as summarized in the FS Update, and if available from the California Statewide Groundwater Elevation Monitoring (CASGEM) Program and State Water Resources Control Board GeoTracker website. c. Groundwater elevation maps will be used to generate contours of groundwater elevation and resulting estimated horizontal flow paths. Groundwater underflow into the Red Zone and groundwater outflow to the Pacific Ocean will be estimated. d. Watershed modeling/groundwater recharge from precipitation and irrigation. Groundwater recharge by precipitation occurs aerially throughout the Hydrologic Analysis Area, and is also focused within sections of the streams during wet-weather flow. Consultant will employ the Distributed Parameter Watershed Model (DPWM) developed by Consultant for this purpose. Parameterization of the DPWM will be completed with publically available data and data collected in Task Cl. The widely-used Parameter-elevation Regressions on Independent Slopes Model (PRISM) will be used to generate precipitation rates that account for orographic effects on a daily time step. Additional climactic data (e.g., wind speed, temperature) will be accessed from local meteorological stations. Vegetation data will be obtained from the USGS Gap Analysis Program (GAP), and soils data will be obtained from the USDA Soil Survey Geographic (SSURGO) and State Soil Geographic (STATSGO) databases. e. Irrigation rates will be estimated based on water-delivery records (if available), the irrigation practices survey conducted under Task Cl, and literature references for irrigation rates in Southern California (e.g., Costello and Jones, 2014). Irrigated areas will be estimated based on the irrigation practices survey and review of aerial photography. 01203.0006/524815.6 A-10 A-31 f. DPWM results will be documented in a series of maps and diagrams that document model input data (e.g., topography, soils, vegetation) and model simulated runoff volumes and deep percolation to groundwater. 3. Septic system recharge. For domestic water users that use individual septic systems, some of the household-consumed water is eventually recharged to groundwater. The presence of septic systems within the Hydrologic Analysis Area will be determined by comparison of the location of residences and sewer infrastructure (e.g., FS Update Figure 7) in consultation with appropriate City staff; it is assumed that septic systems are present where residences are present and sewer pipes are absent. The recharge rate for individual septic systems will be assumed to be 147.5 gallons per day (gpd) assuming 50 gpd per person based on a study of septic system recharge within southern California (Hantzche and Finnemore, 1992), and an average population of 2.95 persons per household in California (U.S. Census Bureau, 2018). Alternatively, water delivery records may be used if available to estimate domestic water usage per household. 4. Change in groundwater storage. As reported in the FS Update, groundwater levels have historically increased in this area due to increase in the rate of groundwater recharge caused by the disruption of drainage patterns and the opening of fissures and cracks following the onset of land movement. Newly collected groundwater level data under Task Cl, above, will be compared to historical groundwater-level data reported in the FS Update to estimate the change in groundwater storage over time. 5. •Identification of Key Sources of Groundwater. Significant sources of groundwater recharge to the Red Zone will be determined from the results of the Water Balance. Groundwater recharge from all sources (e.g., irrigation, septic systems, precipitation) will be summarized in table and graphical form. The results of the Water Balance will be used to provide input on mitigation measures to reduce groundwater recharge. In addition, DPWM will be used to support engineering design of the system dewatering components. F. TASK D. Fracture Sealing(In-filling) As noted in historical reports for the Portuguese Bend area, stormwater has for years flowed out of lower Portuguese, Ishibashi, and Paintbrush Canyons and recharged directly into subsurface groundwater in the landslide head scarp area south of lower Burma Road. Groundwater recharge in the head scarp area promotes slope instability in the Portuguese Bend "Red Zone" area of greatest displacement. Sealing this surface fracture area is key to preventing future stormwater flow into the head scarp and additional lubrication of the slide plane failure surface. 01203.0006/524815.6 A-11 A-32 1. This task consists of the following subtasks: a. Field Survey b. Evaluate Sealing Options 2. Consultant has already conducted a preliminary field survey of the fracture areas while visiting the property on several dates in 2018. In addition, Consultant obtained a high-resolution topographic map from the City that shows landslide area topography with 1-foot elevation contours. The topographic map shows several fractures in the landslide head scarp area. Consultant imported the map into our GIS. Consultant will utilize the GIS system to systematically identify key existing fractures before a supplemental field survey is planned and completed. The GIS work and sitewalk will be completed to inventory the fractures that need to be targeted for sealing. A list of fractures will be prepared that itemizes each fracture area and approximates the length, depth, and width of the fracture that needs to be sealed. A map will be produced showing each fracture and the existing habitat at each location. Total fracture volume can then be estimated in order to develop an overall approach to the task and specify the appropriate equipment and fracture sealant. Several options will be evaluated for fracture sealing that include a variety of equipment, materials, and methods. Various sealing media will be considered such as fill soil, bentonite clay, or soil-cements. Sealant delivery options are anticipated to include simple mixing and pumping as well as mobile long-reach grout rigs. Each option will be presented as a line item in a detailed table that presents a technology summary, advantages, disadvantages, effectiveness, estimated longevity, costs, and other factors, such as potential habitat impacts. The table of options will be presented to the city and community for discussion and evaluation that will ultimately lead to selecting the best option. G. TASK E: City Council Meetings Consultant's anticipated agenda for each meeting: 1. Meeting 1: A preliminary draft schematic design for drainage and dewatering will be presented to the City Council for review and approval prior to proceeding beyond 30% design. 2. Meeting 2: A draft revised pre-construction design incorporating City Council and City staff direction will be presented to the City Council for further review and approval. 01203.0006/524815.6 A-12 A-33 3. Meeting 3: A final 100% construction-ready design will be presented to the City Council. Consultant will prepare PowerPoint files for each meeting for overhead presentation to the City Council and public meeting attendees. Each PowerPoint presentation will summarize the completed work to date and illustrate the proposed engineering options for review, discussion, and approval. Consultant will prepare and distribute meeting minutes highlighting action items. H. TASK F. Public Outreach Meetings Consultant has planned and budgeted for two community outreach meetings, if desired by the City. The meetings are anticipated to be completed at important design milestones. Consultant will receive public comments, including after the 30-day comment period, and prepare a response-to-comments (RTC) document to form the basis for continued discussion and interaction with the community as final designs are selected and approved. The City Council will review and approve the RTC document. Two meetings are anticipated for this Project: 1. Meeting 1: Present and discuss draft proposed plans and receive and discuss community feedback. 2. Meeting 2: Present and discuss final construction-ready design and receive and discuss community feedback. Consultant will prepare electronic presentations using Powerpoint for each meeting for overhead presentation. Each presentation will summarize the completed work to- date and illustrate the proposed draft and final engineering options for review, discussion, and approval. Consultant will prepare and distribute meeting minutes highlighting action items. TASK G: Hydro Augers 1. Design of Hydro-Auger System — Conceptual. In addition to reduction of infiltration, this task includes the following goals: a. Reduce artesian pressures below the basal failure surface b. Reduce steady-state seepage (groundwater flow). Both goals will be achieved by designing and installing a system of hydro-augers. The first set of hydro-augers will be advanced below the postulated basal failure surface to relieve the artesian pressure within the bottom portion of the slide. These hydro-augers will not be significantly affected (i.e., sheared-off, as would likely happen for conventional vertical pumping wells drilled through the base of the landslide) by the current relatively large movement of the sliding mass (presently, on the order of 8 ft/yr). Following the initial mitigation stage to achieve artesian pressure relief and 01203.0006/524815.6 A-13 A-34 reduced infiltration, additional hydro-augers will be installed (with penetration into the sliding mass) to lower the groundwater elevation, reduce steady-state seepage forces, and improve the redundancy and overall longer-term performance of the dewatering system. To enhance drainage/relief of artesian water pressure, a "casing perforating device" may be used. This device is a perforating gun to provide effective flow communication between a cased wellbore and formation water. 2. Design of Hydro-Auger System- Technical Consultant's preliminary design of the proposed hydro-auger system will be based upon the existing information in the FS Update. However, Consultant may propose supplemental subsurface investigation, if Consultant finds that such information would fill needed data gaps and benefit the project, (i.e., would reduce the number and length of hydro- augers). This approach is further described in the "Value Engineering/Monitoring Success" section of this task. The proposed hydro-auger system will be designed based upon the results of engineering evaluations, including 3-D seepage and slope stability analyses. These engineering evaluations will build upon the previous work by the Consultant that was conducted as a component of the FS Update, as follows: a. Expand the 3-D slope stability model (depicted in figure above) with SVSLOPE (https://soilvision. com/product/syslope) of the site to include additional areas affected by landsliding that require mitigation or otherwise influence landsliding, as necessary. The original 3-D slope stability was built as a component of the FS Update b. Refine and update the groundwater elevation surface based upon the results of the Water Balance Study described above c. Apply steady-state seepage and artesian pressure modeling options to more accurately represent the observed phenomena using the program SVFLUX which directly interacts with SVSLOPE (https://soilvision.com/products/ svoffice-ge/svflux-ge). For the FS Update, the 3-D slope stability model included only the manually- entered, best estimate of the piezometric surface, and it only indirectly considered artesian pressure d. Calibrate the model with updated piezometric surface using output from the Hydrology Analysis as available, steady-state seepage, and artesian pressure to match the observed conditions (i.e., Factor of Safety (FS) ? 1.0 (sliding); up to 8 feet per year of measured 01203.0006/524815.6 A-14 A-35 gross displacement) and validate the results using a 2D analysis of a critical cross section) e. Evaluate the effect of "low infiltration" (e.g., using the results of the Water Balance, calculate how long will it take to increase FS to 1.25 and 1.5 and hence mitigate displacements f. Evaluate the following parameters of the hydro-auger system: (i) location of hydro-augers; (ii) number of hydro-augers; (iii) spatial orientation of hydro-augers; (iv) length of hydro-augers; and (v) diameter of hydro-augers. This evaluation will be an iterative process that also includes cost and time considerations. As discussed in the RFP, concurrence by the City will be sought for each "critical" step of this process Upon completion of Step 6, Consultant will develop an implementation schedule (i.e., Gant Chart), design drawings, and technical specifications, and will develop a bid package. Relevant calculations will be submitted electronically (e.g., PDF) with the drawing and specification package, as requested by the City. The constructability and standard detail requirements will be developed in consultation with our proposed drilling subcontractor, Directed Technologies Drilling(DTD). Consultant will also evaluate vertical groundwater extraction wells in this task. Vertical extraction wells are a traditional and effective groundwater extraction technology where installed in appropriate subsurface conditions. However, vertical wells in the Portuguese Bend landslide complex haven proven to be problematic given continual slope failure and land displacement. As a result, as discussed in the FS Update, vertical wells are anticipated to be more cost-effective if installed later in the mitigation program once some slope stability has been achieved with other means, such as hydro-augers. A vertical wells plan, if appropriate, will include design,placement, and cost estimates. 3. Value Engineering/Monitoring the Success Consultant's preliminary design of the proposed hydro-auger system will be based upon existing information provided by the City. It will be developed at a level suitable for development of a bid package. Implementation of the hydro-auger installation will be designed to occur in phases, as discussed in the FS Update. This will allow for review of additional information gathered during each phase of installation, and potential adjustment of the design (if it benefits the project). For example, during the first phase of the implementation, hydro-auger boreholes will be logged, sampled, and tested, and flow out of the holes will be recorded. This is valuable information that will be processed, evaluated, and input 01203.0006/524815.6 A-15 A-36 into our 3-D model of the site. The model will be re-run, and the number and length of hydro-augers might be adjusted accordingly. Additional information that will benefit the project includes: • Current (at the onset of the project/3-D modeling) information on groundwater elevation, flow direction, and artesian pressure along the basal failure surface • Information on the basal shear surface (more accurate elevation contours within the area affected by landsliding) • Information on landslide movement(monument survey) As discussed in the FS Update, information on file, for all three items listed above, is (or will be) dated, and may not be accurate at the level that would most benefit the project. Therefore, during the implementation phase of this project, Consultant may propose to advance and instrument up to three boreholes. The boreholes will be advanced within the bottom third of the landslide mass and will extend beyond the postulated basal failure surface. They will be instrumented with: (a) vibrating wire piezometer; and (b) Time Domain Reflectometers (tilt meters). Representative soil samples for laboratory testing (saturated hydraulic conductivity below and above failure plane)will be recovered as well. 4. Cost-Benefit Analysis Consultant will complete a cost-benefit analysis regarding hydro- auger design, installation, and maintenance compared to the ongoing maintenance cost associated with maintaining Palos Verdes Drive South. The cost/benefit analysis will compare the routine costs and benefits of periodic roadway assessment and repair with the key issues related to the advantages and potential disadvantages of hydro-augers including long-term and short-term costs, slope stability, and short-term and long-term benefits. The analysis will consist of a series of order-of-magnitude costing tables and a summary table summarizing and scoring the pros and cons of each option. Given the compromised nature of the current roadway, the analysis would not be complete without considering complete roadway collapse and repair due to an episodic slope failure event. Consultant's cost-benefit analysis will also consider this scenario. J. TASK H: Utility Coordination Consultant will contact and coordinate with the appropriate public utilities to ensure that utility lines and infrastructure are fully identified and 01203.0006/524815.6 A-16 A-37 protected during upcoming design planning for construction work. Consultant has already identified several utility line locations during property area site walks and using the City GIS layers. Sewer lines, storm lines, and potable water lines in the landslide complex are already input to the GIS system that Consultant prepared for the FS Update and are ready for use during design document preparation. K. TASK I: Prepare construction plans Based on the results of our engineering evaluations, Consultant will prepare a set of full-size construction plans (scaled 22 inches x 34 inches) for the proposed remedial measures. Key features to be included in the construction plan correspond to the expanded sheet titles, as outlined below: 1. Title sheet, showing site vicinity map 2. Construction notes sheet 3. Existing conditions, including site topography, existing utilities, and pertinent site features, such as channel alignments, and fractures 4. Drainage plan showing limits of lined channel installation and fracture infilling (i.e., fracture locations and planned equipment layout) 5. Groundwater extraction plan, showing tentative hydro-auger installation plan and section views as well as locations of vertical extraction wells, if any, included in the design; hydro-auger installation plan will show entry and exit pit locations, diameter, alignment, and confirmatory geotechnical borings for the proposed drains; Drains to be installed first (the first phase) will be clearly labelled 6. Monitoring plan showing locations of instrumentation for evaluating effectiveness of the remedial measures; instrumentation will include existing and proposed survey control points, TDRs, and vibrating wire piezometers 7. Erosion control plan, showing locations and types of temporary (i.e., in- place during construction and, potentially, removed at the end of construction) and permanent (i.e., to remain post-construction) erosion control BMPs 8. Grading plan for provision of laydown areas, equipment access, and working platforms for installation of remedial measures 9. Detail sheets for surface water and erosion control, including fracture infi lling, geosynthetics design for channel lining, and temporary and permanent erosion control BMPs 01203.0006/524815.6 A-17 A-38 10. Detail sheets for the first phase of hydro-auger installation and development 11. Detail sheets for the first phase instrumentation design and installation 12. Construction plans will be submitted to the City in electronic (AutoCAD) format for review and comment at the 30%, 60%, and 90% design completion stages. At the 30% design stage, Consultant will also perform internal peer review of the designs for constructability of the proposed features. Consultant will incorporate City comments and deliver an electronic copy of the bid-ready plan set at the 100% design stage. L. TASK K. Prepare Engineer's Estimate Consultant will develop an engineer's estimate for the proposed remedial work during preparation of the 60% design construction plans, including construction quantities and construction quality assurance program costs. This will be an order- of-magnitude cost estimate for planning purposes and will be developed based on a combination of Consultant in-house cost data for recent similar construction projects, publicly available data (e.g., Caltrans, FHWA), and discussions with the Consultant team subcontractors. M. TASK L. Prepare technical specifications and applicable special provisions 1. At the 30% completion stage, Consultant will outline Technical Specifications and will complete their development at 90% design stage. Work will also include construction quality control guidance for the proposed remedial work. Key features to be addressed in our specifications package include: a. Geosynthetics material and installation guidance for channel lining b. Material type and delivery method for fracture infill c. Pipe material and installation method for horizontal drainage d. Drilling fluid management for directional drilling e. Instrumentation installation and monitoring procedures f. Earthworks for incidental grading g. Applicable APWA Green Book guidance h. Erosion control measures, including typical BMPs, guidance based on NPDES permit requirements, and guidance based on provisions of the Clean Water Act 01203.0006/524815.6 A-18 A-39 i. Recommended inspection and maintenance regimen for hydro- augers, channel lining, and fracture infill 2. Per City requirements, technical specifications will be submitted in hard copy and electronic formats. At the 90% completion stage, Technical Specifications will be provided in electronic format (Microsoft Word). Revised specifications will be submitted in hard copy and electronic formats at the 100% design stage. N. TASK M. Prepare Bid Document Package Upon the City's acceptance of the 100% design stage plans and specifications, Consultant will provide support to the City for development of a bid package. The City will provide an example Bid Document Package and will provide front-end Technical Specifications (including the format for the Notice to Bidders, Table of Contents, General Provisions, Special Provisions, and format for Bid and Contract sections). Consultant will develop Special Provisions by combining project- specific special provisions with the City's Special Provisions. Project Plan Sheets will be referenced in the Bid Documents as an attachment. The assembled Bid Document Package will be provided to the City in electronic format (i.e., PDF, Microsoft Word, and AutoCAD, as appropriate). O. TASK N: Attend meetings and answer RFIs For this task, Consultant will be available to attend monthly meetings with the City and the Ad-hoc Committee during design plan preparation to provide project activity updates and to receive and discuss City input, review, and comment. Consultant will also attend meetings at the City offices during the pre-bid and pre- construction phases of the project to coordinate with the City staff and prospective bidders regarding bid questions, clarifications, and requirements. Consultant will respond to Requests for Information (RFIs) during the bidding and construction phases of the project as needed. A total of four (4) meetings at the City are estimated for this task. P. TASK 0: Final Deliverables &As-Builts Consultant's deliverable for the pre-bid phase will include bid-ready plans, specifications, and a bid package provided to the City in hard copy and electronic formats, as applicable. At the end of the construction, (i.e., in the implementation phase, not as a part of this design-phase scope of work), Consultant will commission an "As-Built" survey of the constructed improvements and submit full-size (i.e., 22 inches x 34 inches) drawings electronically in AutoCAD and PDF formats. Q. TASK P: Estimated Construction Project Schedule 01203.0006/524815.6 A-19 A-40 Consultant will prepare an itemized overall project construction schedule as part of the overall deliverables. The schedule will be built in MS Project and converted to a suitable format for the City if needed such as pdf. The draft schedule will be reviewed by City staff and comment will be incorporated into the draft before a final schedule is prepared. R. TASK Q: Project Surveying DBS&A has teamed with McGee Surveying Consulting for this task. After incorporating earlier surveys that started in 1994, McGee Surveying has completed the City's annual GPS surveys of the landslide complex monuments since 2007 to document land movement on an annual basis in the Portuguese Bend area. The annual McGee Surveying reports form the basis for quantification of overall land displacement and definition of the "Red Zone" area of greatest land movement in the landslide complex. Consultant and McGee Surveying will ensure that any future work is conducted consistent with the methodology of the past work, consistent with the California Professional Land Surveyor's Act, while protecting and maintaining the established survey monuments in the area. All reports as appropriate will be submitted to Los Angeles County to be recorded. Relevant surveying details will be incorporated into draft and final drainage and dewatering design plans as needed. II. As part of the Services, Consultant will prepare and deliver the following tangible work products to the City: A. Design plans, 30%, 90% and Final plans for construction including but not limited to city boiler plate, general provisions, special provisions, technical provisions, bid table and bid package B. Project construction schedule C. Project cost estimate D. Responses to RFIs E. Post construction As-built drawings III. In addition to the requirements of Section 6.2, during performance of the Services, Consultant will keep the City appraised of the status of performance by delivering the following status reports: A. Consultant will work with City staff throughout the project to prepare and submit documents, images, and maps, meeting notes, progress reporting, communications, event timelines, etc., suitable for upload to the City website for public review. Website updates can be generated at any time upon City request. However, Consultant will prepare the website updates on at least a monthly basis for the duration of the project including submittals after public meetings and outreach events. 01203.0006/524815.6 A-20 A-41 B.

INTRODUCTION The City of Rancho Palos Verdes is a scenic, upscale, residential coastal community, with a population of approximately 42,000, located on the Palos Verdes Peninsula of southwestern Los Angeles County. The City of Rancho Palos Verdes is a contract city, meaning that some services are provided by contract with agencies (both public and private) and some services are delivered by the City's own employees. City Government: Rancho Palos Verdes is a General Law City and has operated under the Council-Manager form of government since its incorporation in 1973. Policy-making and legislative authority are vested in the governing City Council, which consists of five Council Members, including the Mayor and Mayor Pro-Tern. The City is fiscally sound and functions on an annual budget cycle. II. PROJECT OBJECTIVE The Portuguese Bend Landslide began moving in 1956, several studies have been performed including the most recent Update to the Portuguese Bend Landslide Feasibility Study. Details and history of the project should be viewed at http://www.rpvca.pov/documentcenter/view/12275. The City is seeking proposals that incorporate both Phase 1 and Phase 2 into one consolidated proposal. The successful firm will provide Engineering Analysis and Design Services for the City's Portuguese Bend Landslide Mitigation Project, Phase I. The City is particularly looking for proposals with innovative and cost saving project approaches, and that clearly delineate the tasks in Phase 1 and Phase 2. 5 RFP for Portuguese Bend Landslide Drainage and Dewatering Project B-5 III BACKGROUND: UPDATE TO THE PORTUGUESE BEND LANDSLIDE FEASIBILITY STUDY The City of Rancho Palos Verdes Department of Public Works provides infrastructure management to all aspects of public facilities which are funded by the General Fund, Capital Improvement Fund etc. The Portuguese Bend Landslide is located within a larger landslide complex between the Abalone Cove and Klondike Landslides. The Updated Feasibility Study (FS) incorporated environmental, engineering, and hydro geologic work completed to address regional slope failure on the greater Palos Verdes Peninsula. The FS was an update of the efforts completed primarily in 1997 and 2000 that characterized the hydro geologic and geotechnical conditions driving landslide activity and proposed a variety of various approaches and technologies to abate slope failure in the Portuguese Bend Landslide Complex. The City hired Daniel B. Stephens & Associated, Inc. (DBS) to include public outreach and generate the FS. Following extensive public outreach, the City Council accepted the FS which is available and should be viewed at http://www.rpvca.gov/documentcenter/view/12275. The FS included preferred technology options that are to be further evaluated and if appropriate, designed through this project: • Directional Subsurface Drains • Flexible Liner System and Components • Groundwater Extraction Wells • Drainage system under Palos Verdes Drive South to the ocean The FS was vetted through a public process as the draft FS was being developed. The draft FS was presented to the City Council. Public comments received following that meeting were reviewed, answered and incorporated into the final FS. Environmental considerations specific to engineering solutions were made known during the City Council meetings and are to be given full consideration during any proposed solutions designed during this process. Specifically any lining within the canyons that is determined to be required are to be limited to the lower reaches of the canyons and placement of lining materials shall be reviewed with Staff, the council and the public to fully disclose where and how material would be installed. IV.

EXECUTIVE SUMMARY C-3 Q November 9, 2018 i cs Mr. Elias Sassoon Director of Public Works City of Rancho Palos Verdes 30940 Hawthorne Boulevard Rancho Palos Verdes, California 90275 Re: Executive Summary for Engineering Analysis, Evaluation,and Design for Portuguese Bend Landslide Drainage and Dewatering(Hydro-auger) Proposal Dear Mr.Sassoon: Daniel B. Stephens &Associates,Inc. (DBS&A),a wholly owned subsidiary of Geo-Logic Associates, Inc. (GLA),is ready to continue providing technical support to the City of Rancho Palos Verdes (City) in their efforts to stabilize the Portuguese Bend landslide complex. Approach to Statement of Work Building on the results of our recently completed mitigation Feasibility Study Update (FS Update), our team's geotechnical,engineering geology,hydrogeology,and civil design experts will move the program forward quickly and efficiently using innovative,yet proven mitigation solutions.Our team is already well up-to-speed,having recently reviewed and studied the relevant site and site history data and completed the FS Update—we can immediately begin working on the remedy.We have also developed an effective working relationship with City staff and the engaged community stakeholders. Our previous stakeholder engagements were well received,our proposed mitigation measures have been thoroughly discussed with all of the stakeholders,and we have been acknowledged for our collaborative nature and ability to balance sensitive ecological and engineering construction issues. The main cause of landsliding at this site is a combination of hydrogeological and geotechnical factors,including the presence of low-strength materials along existing slide planes (i.e.,basal failure plane(s)) and the presence and flow of groundwater. The hydrogeologic (i.e.,groundwater) conditions within the Portuguese Bend landslide are complex. They include not only steady-state seepage within the sliding mass,but also artesian pressure. There is significant recharge that maintains the steady-state conditions,and,likely,also maintains the artesian pressure along the basal failure surface. Based upon our understanding of site geological and hydrogeological conditions,and project constraints,our geotechnical engineering and engineering geology experts developed a three- dimensional (3D) numerical model of the Portuguese Bend landslide complex. This recently completed effort will uniquely enable us to move forward and further improve the model to evaluate drainage,dewatering,and pressure relief options using state-of-the art analytical methodology. The work will be performed in a sequential,phased approach as outlined in the FS Update. We will use the updated,improved,calibrated,and validated model to evaluate various hydro-auger dewatering options,including location,orientation,length, diameter,and rate of dewatering.The updated model will guide us in identifying monitoring approaches to track the Daniel B. Stephens & Associates, Inc. 3150 Bristol Street, Suite 210 0748-4708 Costa Mesa, California 92626 Mr. Elias Sassoon November 9, 2018 Page 2 progress of landslide mitigation and,upon the City's approval,facilitate detailed design and construction planning. The hydro-auger design would not be complete without hydrological evaluations. Therefore,our hydrology and hydrogeology experts will complete a Hydrology Analysis and optimized Water Balance to gather the input needed for drainage and dewatering design as well as future FS tasks, such as quantifying leach field recharge to groundwater. As specified in the RFP,a detailed hydro- auger cost/benefit analysis will also be integrated into our design planning and stakeholder review process. We understand the upper reaches of Portuguese, Ishibashi,and Paintbrush canyons include established,sensitive habitat.The Hydrology Analysis will,in part,help assess the degree to which these critical areas contribute to groundwater recharge in the"Red Zone"area of greatest identified land displacement. Even if the upper canyons are shown to significantly contribute to groundwater recharge in the Red Zone area of greatest identified land displacement(as outlined in the FS Update), our geotechnical model will allow us to evaluate engineering options to minimize subsurface dewatering and reduce or eliminate upper canyon work.We will also optimize fracture sealing(in-filling) in the slide head scarp area to reduce surface water recharge to groundwater while preserving habitat areas. We will balance our proposed work with local utilities and the requirements of the California Environmental Quality Act(CEQA) by seeking to minimize or eliminate potential impacts related to construction,operation,and maintenance of the final design.Our proposed work will adhere to Clean Water Act and National Pollution Discharge Elimination System (NPDES) permitting requirements,and will meet American Public Works Association (APWA) "green book" of plan and specification standards. We routinely produce construction plans,technical specifications, engineer's estimates,and bid packages for a variety of engineering projects.The City will benefit from our extensive experience in developing bid package drawings and deliverables from initial concept to contractor and City bid question-and-answer assistance. We will take a lead role,with City coordination,in conducting contractor pre-bid and pre-construction meetings,and addressing Requests For Information (RFI) during bid package review. DBS&A maintains a thorough and active project management and quality control/quality assurance (QA/QC) program for every project and deliverable,which is led by our Senior Principals. Critical pre-deliverable internal review is an essential component of our work product delivery process. Not only are overall project concepts carefully reviewed to stay on scope,on budget,and on schedule,but the fine details of our work are reviewed to ensure work is of high quality, defensible, and accurate. We will stay in close contact with the City and community stakeholders during preliminary, draft, and final design and deliverable preparation through City Council meetings,public outreach meetings,monthly project meetings,and monthly City website updates.

WORK PLAN C-35 Engineering Analysis,Evaluation,and Design for Portuguese Bend Landslide Drainage and Dewatering(Hydro-augers) C. WORK PLAN The remedies outlined in the FS Update included hydro-auger installation, canyon liners,fracture sealing,and stormwater control in the lower na f Portuguese Bend landslide complex north of Palos Verdes Drive South.The DBS&A team understands that the City and community stakeholders want a\� to implement the remedies outlined in the FS Update in a"phased"manner. , , The objective of a"phased"approach is to validate that the installation methodologies,construction materials,critical design parameters,and impact on critical habitat are appropriate before proceeding to later stages of full-scale construction and cost expenditure.Therefore, our scope of work �- includes development of design plans, specifications,and a bid package as the first phase of each remedy element.This section presents our approach to creating final designs and implementing the remedies identified in the FS Update. Our work plan to execute the proposed scope of work is provided in detail in the following sections. We propose to implement a work-breakdown structure (WBS) process that allows for early City review and appropriate stakeholder input regarding task sequencing, level-of-effort, and deliverables.A preliminary WBS will be prepared listing the major and minor project tasks in chronological order with a simplifying description of the major task elements.This WBS list will serve as the basis for initial discussion and planning in the project kick- off meeting. (For example,the components of the hydrology study will be outlined in the draft WBS to gain consensus before moving forward.) Once final, it will provide the overall structure for project elements and project schedule through project completion.The WBS will also serve as the basis for tracking work task completion,financial accounting, invoicing, and budget expenditure.We have prepared a preliminary project schedule using Microsoft Project software on the following page. The schedule shows the major task elements in sequence with start dates, durations, and end dates.This schedule will be updated as the project tasks are sequentially completed.We understand the City has estimated project completion by September 2019 with construction starting in Spring 2020 and we have developed our schedule to meet this goal. a a Daniel B.

QUALITY CONTROL C-57 Engineering Analysis,Evaluation,and Design for Portuguese Bend Landslide Drainage and Dewatering(Hydro-augers) D. QUALITY CONTROL DBS&A follows an established protocol as written in our corporate Quality Assurance Program Manual (QA Manual) on all our projects.This mature Quality Management Plan corporate QA program,developed from our history of more than 30 years in the environmental and engineering business, includes thorough preparation and planning,establishment of sound procedures, strict adherence to protocol,checks for precision and accuracy,and internal review of documents. In some instances, outside review of documents is used to ensure quality. DBS&A also employs a full-time editing and production group responsible for conducting final editorial reviews and production of all documents to ensure d fl6e,e,�.s«„e„�� e...�;A�e.� quality,accuracy,format,and completeness of reports prepared by DBS&A. Specific procedures for conducting all aspects of the work are included in our corporate Operations Manual.This Manual provides procedures to guide staff in all aspects of the work. It addresses such topics as field procedures, data analysis, health and safety,cost estimating, project management, and reporting. Project-related work at DBS&A is controlled by daily hands- on management of personnel by direct supervisors and assigned project managers.As Project Manager,John J. Dodge, P.G.,and as QA Officers, Stephen J.Cullen, P.G., Ph.D., and Michael Yacyshyn, P.E.,are responsible for ensuring that work is performed in accordance with standard operation procedures outlined in the Operations Manual. In support of our Operations Manual, random project audits are made periodically by DBS&A managers.Additional measures to ensure quality include hiring technically qualified personnel who have high academic achievement records coupled with relevant experience and consistent training of new employees in standard procedures, both administrative and technical, upon employment at DBS&A.We also work with our subcontractors to obtain data in digital format thereby eliminating possible data entry errors. COST CONTROL DBS&A believes that cost control is directly linked to the work plan agreed upon with the client. During all phases of the project,we will monitor our progress with the assistance of our robust accounting system, Deltek Vision, as well as other in-house project management tools.These interactive software tools have proven effective for managing the budgets on numerous simultaneous project tasks.Our success in controlling quality and costs through use of these techniques is demonstrated by the satisfaction of our clients. 53 Daniel B.

Based on the project team's field https://www.researchgate.net geologic mapping, a potential landslide was identified in the ascending slope /profile/Alan Witthoeft south of the proposed basin. Mr. Witthoeft performed back-analysis of the potential landslide to estimate shear strength of the basal shear surface and performed static and pseudostatic slope stability analyses to evaluate the translational and rotational stability of the slope. The results of the hillside stability evaluations indicated that calculated factors of safety for the proposed condition are relatively low and could be approaching unity. The results further indicated that the construction of the proposed storm water A-24 C_88 Alan F. Witthoeft, PE, GE Gev-Logic Paget ASSOCIATES basin does not adversely affect the stability of the approximately 125-ft high ascending slope. A qualitative evaluation of the impact of an approximately 300-ft high slope was performed as well.

Daniel B.Stephens&Associates,Inc. A-34 C-98 Hannah Erbele °� �P as Page 2 Asset Management Plan for Water Supply Wells, California Water Service Company, California Cal Water operates over 800 water supply wells throughout California, and the California Public Utilities Commission requires Cal Water to submit a General Rate Case application every three years to demonstrate that their water rates accurately reflect the cost of providing service. The Asset Management Plan identifies and characterizes aging infrastructure in Cal Water's districts, such that deteriorating wells can be identified and prioritized for replacement (new well installation) or rehabilitation (well liner installation). Consistent with industry standards (such as American Water Works Association standards), Ms. Erbele provided an assessment of the condition, criticality, and long-term reliability of wells within the Cal Water Districts. Litigation Support for Contaminated Groundwater Site, Carson, California Ms. Erbele developed an electronic master site plan for the Site area in the industry-standard GIS. The GIS site plan was a compilation of relevant data extracted from the library of approximately 841 pdf files into a single- location for critical review and evaluation. In addition, environmental data such as groundwater elevation contours, groundwater flow direction data, and environmental sampling data for soil vapor, soil, and groundwater was added over the infrastructure imagery to develop concise maps and presentation slides for the Site area and adjacent properties. Groundwater flow and groundwater contaminant maps for all included properties combined were developed to provide a regional understanding of contaminant sources, fate, and transport. Development of a master site plan for the Site area and adjacent properties allowed for a unified understanding of environmental conditions regarding the sources,fate, and transport, of identified soil, soil vapor, and groundwater contaminants in the Site area. Puente Valley Operable Unit, San Gabriel Valley, California Puente Valley Operable Unit is one of four Superfund sites located in the 170-square-mile San Gabriel Valley.

Over-irrigation activities from residential areas were suspected of contributing to groundwater mounding in the shallow aquifer and subsequent selenium flux from the underlying Monterey formation. DBS&A constructed a detailed water balance with a focus on the upper Watershed in the vicinity of the reservoir and adjacent neighborhoods to characterize the potential impact of suspected over-irrigation and reservoir design discharge on shallow groundwater mounding and selenium flux in the Watershed. DBS&A installed a set of seven piezometers to supplement the existing piezometer network near the reservoir.Stable isotopes of oxygen and hydrogen (delo/delD) were utilized to evaluate groundwater recharge from various sources. DBS&A also installed a surface water staff gauge to compare surface water elevation to groundwater elevation in nearby streams. DBS&A collected continuous flow rate data from storm water lines in the area to assess surface water discharge related to irrigation rate and frequency. DBS&A also conducted soil,groundwater,and surface water sampling and analysis to evaluate selenium impacts. A greater understanding of the sources,occurrence,and mechanisms of selenium flux enabled the City to ultimately design remedial measures for selenium impacts in the Watershed. Daniel B.

Due existing buildings to to access to an existing shoring system at the contaminated groundwater. site,the majority of the barrier installed required high-pressure jet-grouted columns to form the barrier. The grout barrier layout consisted of 600 linear feet of jet-grouted elements that overlapped with the ends of a 185-foot-long slurry wall.The barrier was 22 feet high,with 4 feet above and 18 feet below the static water table.Overlapping elements were installed in an alternating pattern with additional grouting near existing shoring piles. Due to site limitations,the only feasible method to access targeted groundwater was to install horizontal wells underneath existing structures. DBS&A designed and oversaw the completion of three horizontal wells with approximately 180 feet of screen and a total length between 280 and 320 feet. Drilling initiated through the side of a 20-foot-deep excavation, proceeded horizontally underneath existing buildings,and daylighted in an adjacent parking area. DBS&A made connections to tie the horizontal wells in to both the north and south sides of the project area,which allowed extraction from both ends of the site.This project was the first application of horizontal vapor extraction wells by the NMED.

DBS&A is working closely two existing storm water with the installation contractor to develop a design that achieves both long-term retention ponds performance and addresses constructability constraints. • Culvert design to route Designing the conveyance line also faced challenges due to extremely steep water from upstream slopes; unstable and fractured rocks in the drainage limiting anchorage points; of the new berm and rocks with sharp edges that may gauge the pipeline during thermal expansion and under the existing contraction if not properly managed;and limits on anchorage locations due to soil Los Alamos Canyon contamination. DBS&A's design team worked with engineers from pipe suppliers Roadway into the to pipe support manufacturers to produce a design that will work within these existing Los Alamos constraints. Canyon channel The design of the diversion pipeline considers impacts to historic and cultural resources and sensitive species.Where the pipeline crosses an historic trail,a footbridge will allow continued trail access. Located in core habitat for the Mexican Spotted Owl, noise and equipment restrictions are in place during the pipeline construction window. Planning for the design phase takes these constraints into account to ensure to comply with natural and cultural restrictions on-site. Daniel B. Stephens &Associates, Inc.

DBS&A completed permit- level calculations and drawings to update the landfill's closure plan,subsequently submitted to NMED. DBS&A is completing construction level plans and specifications to implement the recommended improvements.These documents cover re-grading existing stormwater ponds, installation of new culverts,and installation of improved emergency spillways on stormwater ponds.
