Some of our related Projects are described below. City of La Quinta – Washington Street at Highway 111 Triple Left-Turn Lanes Mr. Carlos Ortiz and Mr. John Dorado, under their previous firm, prepared a Traffic Engineering Report for the City of La Quinta to analyze the Washington Street at Highway 111 intersection level-of-service (LOS) under existing and future conditions in order to determine preliminary geometric design and improvement alternatives that will mitigate operational deficiencies. The analysis primarily focused on adding 3rd northbound and southbound left-turn lanes, adding 2nd eastbound right-turn lane, adding an exclusive westbound right-turn lane. As part of the analysis, the traffic signal operations was evaluated to determine the overall intersection deficiencies and included the following: right turn overlap phasing, and southbound defacto right-turn lane. Further analsysis was conducted to minimize right-of way take, and included the following: lead-lag traffic signal operations for northbound/southbound left-turn movements, reduction of lane widths for westbound through traffic to minimize impacts/relocation to the existing high pressure gas vaults, and merging analysis along the west leg of the intersection. Intersection Geometric Drawings, utility research and right-of-way mapping was provided. In addition, two alternatives preliminary geometric intersection plans were provided and probable construction cost for the selected alternative was provided. After the approval of the preferred alternative, Final PS&E and cosntruction support was provided to the City of La Quinta. PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 3 City of Coachella - Five Traffic Signal Improvements This project consisted of the preparation of conceptual and final plans, specifications, and estimates (PS&E) for roadway improvements, signing/striping, traffic signal, and signal communications improvements at five (5) unsignalized intersections. The City of Coachella conducted traffic signal warrants at these locations and based on the evaluation, these intersections warranted the installation of traffic signals. After the project was awarded, the City expanded our scope of services to include roadway improvements, signal timing plans, additional bike lanes, and wireless communications. Ultimately, these signals will be interconnected via the City’s proposed fiber optic communication system and to the new Traffic Management Center (TMC). Critical project elements include close coordination with the utility companies especially the Imperial Irrigation District (IID) for overhead line/power pole relocations and service (power) for the signals, and the Coachella Valley Water District (CVWD) for relocation/removals of their existing facilities. City of Mission Viejo – Intersection Improvements This project consisted of the preparation of plans, specifications, and estimates (PS&E) for signing/striping, traffic signal modifications, raised median/roadway improvements, ADA pedestrian ramps, landscaping improvements, and street lighting improvements at two signalized intersections, Alicia Parkway/Marguerite Parkway, and Santa Margarita Parkway /Marguerite Parkway. The objective of the project was to increase capacity and improve traffic flow at each intersection by providing dual left- turn lanes and increasing the width of existing Class II bicycle lanes; hence providing de-facto right turn lanes. The primary project elements and street improvements include median modifications, new pavement sections at full- depth AC (12” minimum), pavement overlays when transitioning from new to existing pavement, slurry seal within the limits of new striping and pavement markings, maintain existing drainage patterns, maintain existing roadway cross slopes, removal existing and construction of a new catch basin within the Alicia Parkway median, maintain the existing landscaping “theme”, retrofit existing or provide new water savings type irrigation nozzles, replacement and/or relocate median trees and plants, upgrade traffic signal pole(s) as necessary in order to provide the proper signal head placement for the new dual left turn lanes and re-aligned through traffic lanes, provide potholing at proposed signal pole location(s), provide new countdown pedestrian heads, provide layout of new roadway striping and pavement markings that are consistent with the proposed roadway improvements, construct ADA compliant pedestrian ramps, and new advance and presence loops for vehicle and bicycle lanes. City of Palm Springs - HSIP Cycle 8 Project The project consists of providing traffic engineering, civil engineering, and environmental services to secure environmental documentation approvals; Caltrans encroachment permits; and preparation of plans, specifications and estimates (PS&E) for 14 signalized locations including construction support for the City’s Traffic Signal Improvements (HSIP Cycle 8) project. The purpose of this project is to improve safety and visibility of the traffic signals by upgrading traffic signal equipment and signing/striping to the latest standards, protected left turn phasing, ADA compliant access ramps, and install advanced dilemma zone detection for high speed approaches at the 14 intersections. The proposed project improvements include, but not limited to: removing existing five-section protected/permissive signal heads, mast arms, and signal poles; installing signal heads on new mast arm and traffic signal pole; implementing advanced dilemma zone protection; installing ADA compliant pedestrian access ramps; providing new striping and signing; and establishing connections of the traffic signals to the Traffic Management Center (TMC) at City Hall. This project also requires the preparation of environmental documentation to meet the National Environment Policy Act (NEPA) and California Environmental Quality Act (CEQA) requirements and clearances. In addition, this project includes a left -turn phasing and level of service (LOS) analysis to determine the left-turn phasing, as well as signal timing upgrades that are associated with the implementation for advanced dilemma zone detection system.

RELEVANT EXPERIENCE x CVAG - Coachella Valley Association of Governments Regional Signal Interconnect Project x Indio - On-Call Environmental Services x Indio – Road Diet x Palm Springs - 14 HSIP Intersection Improvements SECTION 2: PROJECT UNDERSTANDING 2.1 Project Understanding The City of La Quinta is requesting proposals from selected firms to provide design and construction support services for the preparation of plans, specifications and estimates (PS&E) for the Washington Street at Fred Waring Drive, Triple Left-Turn Lanes Project. The purpose of the proposed project is to achieve a Level-OF-Service (LOS) E or better during the peak hours and peak season. The proposed improvements will alleviate traffic congestion at the intersection and improve traffic flow by constructing the following improvements: 9 Adding a third left-turn lane for northbound, southbound, eastbound, and westbound directions 9 Maintain existing lane configurations with reduced lane widths 9 Modify existing raised medians and driveways 9 Minimize right-of-way take 9 Minimize utility relocation 9 Modify traffic signal 9 Maintain access for pedestrian, bicyclists, and transit The proposed addition of a third left-turn lane in each direction will require the following improvements: Northwest Quadrant - Widening of the north leg of Washington Street will include curb, gutter, and sidewalk in front of the Washington Plaza businesses. Included in this widening will be the reconstruction of the driveway into the business park, as well as the reconstruction of an under-sidewalk drain. Almost 800’ of curb, gutter and sidewalk will be reconstructed on the north side of Fred Waring Drive. This includes an under sidewalk drain, a driveway, and relocation of a catch basin. While designing the reconstruction of the two driveways mentioned above, attention will be paid to providing an ADA path of travel across/around both driveways. The Palm Desert City monument sign in the NW corner of the intersection will be surveyed in detail to assure we are able to protect the monument in place. When performing research of the improvements at this location, we identified an abnormally high Q10/Q100 per the Tract 19478 improvements and we want to confirm there aren’t any historic ponding/drainage issues in the NW quadrant of the intersection. Southwest Quadrant - Widening the west leg of Fred Waring Drive will require reconstruction of approximately 350’ of curb, gutter, and sidewalk, including relocation Years of Experience: 5 Education: BS, Bioenvironmental Sciences PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 8 of an existing catch basin. Preliminary plans indicate a widening of 3’ to the south. We will identify any potential impacts to the existing drywell and existing retention basin south of Fred Waring Drive and we will identify options to minimize or eliminate any impacts to the drywell or the capacity of the retention basin. Southeast Quadrant - Widening of Washington Street south of Fred Waring Drive will be accomplished by restriping the traffic lanes between the existing curb locations. The only impacts to the southeast quadrant occur on Fred Waring Drive. The preliminary plans indicate sidewalk will be located adjacent to the existing perimeter wall on the south side of Fred Waring Drive. We will have our survey team locate the wall footing at a few locations to assure it is below the elevation of the sidewalk and insure there aren’t any conflicts between the sidewalk and perimeter wall footing. If the footing is a potential conflict, a retaining curb or small stem wall will be designed to protect the structural integrity of the perimeter wall. Northeast Quadrant - Improvements in the northeast quadrant will be fairly straightforward. It includes curb and gutter reconstruction on Fred Waring Drive and Washington Street, as well as the reconstruction of the sidewalk and bus bay on Washington Street. The City has a 20’ sidewalk/landscape easement as dedicated per Parcel Map No. 31876 that we will constrain construction limits too as part of our design efforts to minimize right of way/temporary construction rights. We have also identified the following “other” potential improvements that the RFP did not emphasize, which should be considered as part of the project improvements: 9 Align all traffic signal heads with oncoming traffic based on triple left-turn lanes and through lanes (as applicable) 9 Modify landscaping and irrigation per proposed improvements 9 Maintain new fiber optic communication system and ITS elements that will be installed by CVAG’s Traffic Signal Synchronization Program. 9 Provide new signal timing plans due to the additional left-turn lanes 9 Relocate Sunline bust stop shelter (or upgrade facility) In order to achieve the project goals, the selected firm must have a complete understanding of the project elements involved, an understanding of the planning the Cities of La Quinta, Indian Wells, and Palm Desert have conducted; an understanding of local, state and federal requirements; and most importantly a methodical and innovative preliminary engineering and planning process to complete the final design and preparation of bid documents. We assure that ADVANTEC is the best qualified firm to successfully deliver the Design Services for the Washington Street at Fred Waring Drive, Triple Left-Turn Lanes Project. 2.2 Key Project Elements and Strategies Based on our project understanding, we have identified some key project elements and proposed strategies leading to the successful completion of the project. It is essential to understand the following key project elements and strategies to facilitate the planning and design process. These key project elements may have an impact to the project if not properly addressed in the planning and design process. The strategies that we propose will reduce potential project impacts, including project delays; it will help expedite and facilitate the planning, design and completion of the improvements; and provide cost savings solutions to the City of La Quinta. Field Review Goal: To ensure consistency of the data collected during our field review and inventory, and evaluation of existing conditions. Strategy: The ADVANTEC Team uses senior level staff to conduct the field re views. ADVANTEC uses standard field review forms and worksheets to ensure consistency of the field review. The ADVANTEC Team will perform an in-depth field review of the roadway, drainage, and landscaping improvements, traffic signal and communications, and signing/striping. Each item inventoried will include an identification number, description, and an assessment of the condition while in the field. ADVANTEC will use our standard field review forms in order to document this information in clear concise manner that will ensure consistency of the field review and inventory. ADVANTEC’s task leaders and team members that are assigned to conduct the field review and assessment are senior civil PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 9 and traffic engineers. This benefits the City by providing results are accurate and precise, which allows decision making about our next steps (e.g. recommended improvements) to be made concisely and made with confidence. Line of Sight Analysis Goal: Provide the proper line of sight clearance based on the drivers’ point of view due to the roadway improvements and various horizontal and vertical roadway curvature. Strategy: Use the Highway Design Manual sight distance guidelines to determine the line of sight clearance, which takes into consideration the roadway classification, design or posted speed limit, stopping sight distance (in feet), and the horizontal and vertical roadway curvature. ADVANTEC will prepare a sight distance analysis from the driver’s perspective at the project intersection. This will be prepared during the preliminary engineering process to determine if there are any line of sight issues that should be addressed due to existing conditions or due to the proposed project improvements and to provide correctable solutions. Intersection Level-Of-Service (LOS) and Queuing Analysis Goal: Provide the intersection LOS based on current and forecast traffic volumes to determine the existing and future traffic demands. Provide left-turn lane queuing analysis to provide proper lane capacity at all left-turn lanes. Strategy: Use similar analysis that was conducted for the Washington Street and Highway 111 Triple Left-Turn Lane Project. This analysis was conducted by our Project Manager Carlos Ortiz. ADVANTEC will prepare intersection LOS using current 2019 traffic counts that have been collected as part of CVAG’s Traffic Signal Synchronization Program during peak season. In addition, ADVANTEC will forecast the traffic volumes to anticipated opening year volumes (2020) and determine the LOS with the proposed improvements. In addition, a queuing analysis will be provided to determine adequate left-turn pocket storage lengths for forecast year 2020 with recommended intersection improvements scenario. Similar intersection analysis was provided the ADVANTEC Team (Carlos Ortiz and John Dorado) during the planning phase of the Washington Street at Highway 111 Left-Turn Lane Project. Vehicle and Truck Turning Analysis Goal: Ensures that vehicle and trucks have the proper turning clearance within the proposed triple left-turn lanes, minimize encroachment into the adjacent lane, and eliminate conflicts of opposing left turns. Strategy: Use the Highway Design Manual truck turning templates or software (AutoTURN), and guidelines at the intersection to ensure adequate clearance is provided including opposing left-turn conflicts, and proper set back of striped median noses. This is a simple exercise that should not be overlooked because it can be critical to the design and operations of the signalized intersection. For example: If the intersection is not wide enough, there may be conflicts between opposing left-turns. In this case, we would recommend the signal operations to be lead-lag to avoid simultaneous left turns. ADVANTEC considers this as best practice and will provide truck turning analysis at the intersection to ensure potential truck turning conflicts are avoided as well as taking into consideration of the roadway, traffic signal and signing/striping design and operations. Roadway Cross Slopes Goal: Address “adverse” roadway cross-slope and excess roadway paving against curb and gutter, and inlets. Strategy: Evaluate pavement sections to ensure most cost-effective roadway paving improvement approach; grind and overlay and/or remove and reconstruct. PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 10 ADVANTEC’s public works engineers will evaluate the roadway cross slopes and recommend improvements that minimizes impacts to the existing cross slopes and drainage. The existing super-elevated roadway segment on the south leg of Washington Street shall be maintained. Our goal is to minimize the variation in the cross slope in order to maintain the drainage and impacts due to the new improvements. The same process will be taken into consideration for all inlets within the project limits. The ADVANTEC Team will conduct a thorough pavement analysis to ensure the most effective pavement improvement strategy is selected which addresses the existing roadway efficiencies and provides for an adequate roadway pavement life spam. ADA Compliant Pedestrian Ramps Goal: Assess deficiencies and provide recommendations and/or prepare design improvements to comply with ADA requirements for the proper clearance width and ADA compliant pedestrian ramps. Strategy: ADVANTEC will perform a thorough review of the project locations in order to identify non-ADA compliant pedestrian ramps and clearances. This includes documentation of other constraints and locations may require special design considerations. It’s important to address the need for ADA compliance. ADVANTEC’s public works and traffic engineers will evaluate ADA compliance at the project locations by examining the sidewalk pathways and pedestrian ramps. We are assuming that our project limits for ADA compliant improvements extend between curb return areas. Based on our thorough field investigation, ADVANTEC will discuss with City staff the recommended improvements that will necessary to meet ADA standards. The ADA standard minimum clearance width is 4 feet along walkways without obstructions, and ADA compliant ramps must have truncated domes with the proper cross slopes. This will also include an evaluation pedestrian push button types and locations for ADA compliance. Utilities Goal: Notify and coordinate with all utility companies along the project limits. Strategy: Coordinate with utility companies during the preliminary engineering and design phase in order to stay clear and/or identify potential utility impacts and provide alternative solutions. This project will require close coordination with utility companies to avoid any conflicts during the construction and minimize utility relocations. Coordination with the utility companies will be required to determine the location of the existing utility lines along the project limits and intersection, in order to provide proper vertical and horizontal clearance at locations where new improvements, including new traffic signal poles. Field verification of other physical constraints must be addressed during the preliminary engineering and design phase in order to avoid change orders during construction. Landscape Improvements Goal: Maintain landscaping “theme” and minimize visual impacts to existing decorative monuments. Strategy: It is anticipated that impacts to existing landscaping and hardscape will be minimized. The ADVANTEC Team will provide a through review and identify existing landscaping areas and property monuments. It is anticipated that landscape theme will be maintained. Relocation of traffic signal cabinet and installation of new signal poles will take into consideration the existing properties’ monuments to minimize visual impacts. PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 11 New Traffic Signal Pole, Signal Heads, and Signal Equipment Upgrades Goal: To verify that new traffic signal poles are required based on the roadway improvements, the additional lanes, and new lane alignments. This includes providing the proper signal head alignment for oncoming vehicles including other potential signal equipment upgrades. Strategy: ADVANTEC will conduct a thorough investigation and layout of the existing traffic signal poles, mast arms and signal heads to determine if they can accommodate the new roadway improvements and oncoming traffic lanes. This will be based on Caltrans and CAMUTCD requirements. This strategy also includes developing an inventory list and criteria justify other recommended improvements. ADVANTEC will provide assessments of the existing traffic signal equipment using criteria we develop with the City’s approval in order to clearly indicate the reasons why certain traffic signal equipment are replaced, while others are not. Our layout of existing conditions will clearly identify if new traffic signal poles are needed due to the addition of a 3rd left-turn lane on each approach. An inventory matrix will be provided, and it will include our assessment of existing conditions and recommended upgrades. This will be used help determine our preliminary engineering construction costs to ensure that are within the budget allocated for construction. New Traffic Signal Pole and Potholing Locations Goal: Determine if there are utility conflicts prior to ordering and/or installing a new traffic signal; and as a result, to determine the proper traffic signal pole location. Strategy: Determine new traffic signal pole locations per on CAMUTCD standard pole pl acement and to provide clearance from existing underground utilities, and avoid any conflicts during construction of the project. In order to determine the new traffic signal pole locations, there are several factors that need to be taken into consideration such as: conducting the proper research and layout all existing underground utilities, the clearance between pedestrian ramps and the proposed pole location (typically 1’), and the CAMUTCD standard pole placement – typically 5’ from back of crosswalk or limit line, and 3’ offset from curb face – if the pole cannot be placed within the CAMUTCD parameters, then an additional pedestrian push button pole will be recommended. If new traffic signal poles are required, then our initial recommendation is to remove the existing traffic signal poles and foundations, and install the new traffic signal poles at the same location. This would minimize any utility conflicts because it is assumed that there would not be any utility conflicts since we are using the same pole location. Although during construction, it would require a temporary traffic signal pole and overhead wiring to maintain the signal and facilitate the work. If we cannot use the same pole location as existing, then we would make sure the new pole location is clear of all below ground and above ground utilities, and determine if potholing will be required. We are including Potholing Services as Optional Services in Section 3. Signing and Striping Assessment Goal: Incorporation of clear and concise signage, striping and markings consistent with the project objectives. Strategy: Evaluate existing conditions and need for enhancements to improve circulation, visibility and minimize delays. Prepare comprehensive plans consistent with the proposed improvements and that meet the latest CAMUTCD requirements. The proposed improvements will include re-striping and modifying existing crosswalks, advance signage and pavement markings, and re-striping of traffic lanes along the project limits including bicycle lanes and right-turn and left-turn lanes. All existing regulatory, warning and guide signs will be evaluated to determine if they meet the latest California MUTCD (CAMUTCD) requirements, including reflectivity requirements. If required, additional signage will be recommended. Based on our project understanding and key project elements and strategies, ADVANTEC has a thorough understanding and a proven process to successfully deliver the project improvements that provides the City of La Quinta with the tools to meet their project goals. Figure 2.1 illustrates the proposed project improvements per the RFP, and other potential improvement opportunities that ADVANTEC has identified along the project limits and the Washington PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 12 Street/Fred Waring Drive intersection. We are recommending increasing the lanes adjacent to opposite left-turn lanes and adjacent to raised medians to 12-ft. Also, lane widths reduction at the intersection to minimize right-of-way take. Other design opportunities are highlighted on the exhibit. 2.3 Project Approach Based on our understanding of the key project elements, ADVANTEC’s project approach and methodology will ensure successful delivery of the professional civil, and traffic engineering planning, design, and construction support services for the proposed improvements. PRELIMINARY ENGINEERING Initial Project Team Meeting - ADVANTEC will meet with the City to obtain additional information and discuss critical items that may affect the preparation of the street improvements, drainage, landscape improvements, traffic signal improvements, signing/striping improvements, and stage construction/traffic handling. In addition, plans and technical preparation standards will be discussed with City staff. Coordination and review process with the cities of La Quinta, Indian Wells, and Palm Desert will be discussed. Finally, the project schedule will be discussed in detailed, including construction moratoriums and construction activities during the high season. Data Collection - ADVANTEC will request all existing reference documentation from the City of La Quinta, Indian Wells, Palm Desert, and other agencies, including improvement plans (street, storm drain system, landscape, water, sewer, traffic signals, signal communication, signing/striping, etc.), aerial photographs, right-of-way information and other applicable data. Initial Utility Coordination - During this phase, ADVANTEC will start establishing utility company contacts and request record drawings to show on our improvement plans, and identify if our proposed project improvements impact their facilities. If any utility relocations are required, ADVANTEC will provide reference plans and data to the agencies so they can plan any relocations of their utilities. A notice and final plans will be transmitted to the affected utility companies requesting them to contact the City to coordinate any adjustments and relocations. The information will be maintained in a matrix and will be updated periodically and provided to the City of La Quinta. Field Review - Experienced senior civil and traffic engineers will perform an in-depth field analysis to verify record information along the project limits. A photo log of each of the project intersections and corridors will be maintained. ADVANTEC will provide the field notes on a Project Notebook to the City for their use during the review process. The Project Notebook will have field note check lists, photographs, marked as-built plans, and field notes including possible issues and/or constraints. Project Survey and Mapping - Our subconsultant, Mark Thomas, will complete the survey services within fifteen working days upon our authorization to proceed. They will perform a field topographic survey of the proposed project sites to document existing site topography and planimetrics. Additional details are provided in the Scope of Work section. Prelminary Improvement Plans and Budgetary Cost Estimates - ADVANTEC will prepare the preliminary improvement plans that will include base mapping from the as-built information, topographic survey and information we obtained from our detailed field review. It will include intersection LOS, vehicle and truck turning analysis, recommended improvements, high level design, pertinent details, potential conflicts and concerns, and alternatives and associated budgetary cost estimates. ADVANTEC will set up a meeting with City staff to review our recommended improvements and budgetary cost estimates. We will identify any critical issues and/or constraints that may impact our design. Our goal is to obtain buy-off on the recommended improvements by City of La Quinta, Indian Wells, and Palm Desert staff and move toward the final engineering design phase. This will be considered our preliminary design phase at 35% submittal. It is anticipated that all project improvements will be determined in order to move forward to the final engineering and design stages. 2.4 Project Management Approach The ADVANTEC Team's management approach has been proven on past similar Civil / Public Works / Traffic Engineering Projects to be effective in meeting or exceeding client goals for completing assigned projects on or ahead of schedule and within or below budget. Comprehensive work planning and developing a proactive project team relationship will be critical to the successful management and delivery of this project. 2.5 Quality Assurance (QA) / Quality Control (QC) Plan The ADVANTEC Team’s QA / QC Program is a continuous process used not just at project milestones, but also on a daily basis as work flows from desk to desk, discipline to discipline and consultant to client. Our manager and task leaders will oversee their staff on a daily basis. We will identify key contacts for ease of inquiries regarding project status. Mr. Carlos Ortiz will work with Mr. Keith Rand with the management and implementation of our QA/QC plan. They have served in this role for similar projects and are an expert in specification requirements such as those needed for federally funded projects. PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 13 Figure 2.1 – Washington Street at Fred Waring Drive Proposed Project Improvements PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 14 SECTION 3: SCOPE OF WORK PROGRAM 3.1 Scope of Work This section provides ADVANTEC’s detailed approach and scope of work program to complete the City of La Quinta’s Washington Street at Fred Waring Drive Triple Left-Turn Lanes Project. We have developed our scope of work by task, subtask and deliverables based on the professional services indicated in the RFP, the project elements, and our project understanding and approach. We will coordinate with City staff at the onset of the project to discuss project goals, objectives, constraints, requirements and schedule with a clear path to success. Task 1 Project Management - ADVANTEC will provide Project Management activities through all the aspects of the project including project administration, monthly progress reports, invoices, and thorough quality control. ADVANTEC will prepare a detailed work plan, project schedule and prepare progress reports. The monthly progress reports will include accomplished tasks for the month, anticipated progress for the next month, pending issues and schedule completion target dates. ADVANTEC will schedule and conduct a kick -off meeting with the City to discuss the overall project, planning and design objectives, constraints, requirements, schedule, develop action items, and understanding next steps. During the kick-off meeting, ADVANTEC will coordinate with City staff to determine if we need to assemble a Project Development Team (PDT) and following up with PDT meetings. ADVANTEC will schedule and conduct meetings for project status and to review comments for milestone submittals to ensure all City staff members and participants aware of the project status, critical milestones and decision points including review of project schedules, planning activities, concepts, design, and specifications. ADVANTEC will prepare and distribute meeting agendas, meeting minutes, and an action item matrix to the project team for each meeting that is held. For this task, we propose to conduct the kick-off meeting and up to six meetings at City Hall. Deliverables: Project management and coordination, kick-off meeting attendance, six (6) meetings at City Hall including monthly progress reports, project schedule updates, meeting agendas, meeting minutes, and action item matrices. Task 2 CEQA Documents - The ADVANTEC Team will conduct environmental documentation in support of the Project. Based on preliminary review of the vicinity map provided in the RFP, a brief site visit to log existing conditions of the project site, and experience with other roadway improvement projects, our Team believes that the Project is Categorically Exempt from the provisions of the California Environmental Quality Act (CEQA), under a Class 1 exemption for existing facilities. The addition of left-turn lanes is not a capacity-increasing improvement, so the Project would not result in any substantial environmental impacts associated with greater through traffic. Additionally, the Project is proposed within the public right- of-way (ROW) of at the intersection of Washington Street and Fred Waring Drive. Developed (disturbed) land surrounds the intersection except for a vacant parcel to the northeast. Project improvements would result in minimal land disturbance (area and depth) and evidence of disturbance within the public ROW on the vacant lot vastly reduces the potential for environmental impacts from development of the Project. A review of aerial maps dating back to 1996 indicate that the soils on the perimeter of the vacant parcel were previously disturbed and soil stabilizer applied. Additionally, in the absence of sidewalks, a visible path has been etched into the ground where people utilize the vacant property to access the intersection and the bus stop on Washington Street. A CNDDB search yielded negative results, but due to the high volume of rain experienced this winter, various vegetation is present on the vacant site adjacent to the Project intersection. Although our Team biologists do not expect to encounter any sensitive species on the site, we recommend a biological field survey be conducted prior to preparation of the Notice of Exemption (NOE) to ensure Project development would not significantly affect any special-status species, because a CE only applies if the project would not result in any significant impacts. Task 2.1 Project Initiation / Coordination – Our subconsultant’s Project Manager will attend a kick-off meeting with the project team and City Staff to discuss the scope of work and schedule for CEQA Compliance for the Project. At this meeting, Our Team will take a close look at the location and nature of specific proposed activities associated with the Project. The City will provide us with all project data prior to preparation of the Notice of Exemption. Deliverables: Project Initiation / Coordination Task 2.2 Prepare CEQA Notice of Exemption – Our subconsultant will prepare a Notice of Exemption (NOE) for the Project, which will include the following: (1) a cover letter to the County Clerk, (2) the NOE including findings for a CEQA Categorical Exemption (CE), and a map of the project site and surrounding area. Dudek will file the NOE with the County Clerk for a review period of 35 days. Our subconsultant will also provide a copy of the NOE to the State Clearinghouse. We anticipate that the City will provide one set of consolidated comments on the cover letter, findings and NOE prior to submittal to the County Clerk and the State Clearinghouse. Deliverables: One (1) electronic copy of Screen-check and Final NOE to City Staff PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 15 Task 3 Utility Coordination - Utility notification and coordination will be required to ensure quality design and help eliminate utility conflicts during construction. Utility notifications will be provided to the various utility owners within the sphere of each project intersection; the notifications will be prepared using the City’s letterhead. ADVANTEC will request locations for existing and proposed underground and overhead utilities, including high risk utilities. The utility information provided by the agencies will be delineated on the plans based on their record drawings and our field review. The location of our proposed improvements will take into consideration of the existing utilities. In the event of any utility conflicts, ADVANTEC will coordinate the relocation of all utilities affected by the project. Our goal is relocating their facilities prior to the start of construction of the project improvements. ADVANTEC will compile all utility coordination and information in a matrix format to include dates of notification, persons/utility notified and responses from the utility company. Letters will be sent to the utility companies requesting their review and verification of their facilities during the preliminary and final plan submittals in order to obtain their concurrence with the information shown on the plans. Copies of this information will be updated periodically and provided to the City of La Quinta at the scheduled project meetings and/or as the information has been received. ADVANTEC will conduct utility coordination throughout the design phase of the project. Please note: ADVANTEC’s fees do not include fees or costs associated with the processing and collection of as-built plans or documentation from the utility companies. Typically, fees are waived when submitting utility requests using the City’s letterhead. Deliverables: Utility notification and coordination, utility letters, utility plans and utility coordination matrix. Task 4 Base Maps Task 4.1 Research of Record Documentation and Field Review - ADVANTEC will coordinate with City of La Quinta, Indian Wells, and Palm Desert staff, collect and review available data for use and reference associated with the project improvements. ADVANTEC will conduct a thorough field review of existing conditions along the project limits for the proposed street and drainage improvements, any landscape improvements, traffic signal improvements, signing/striping improvements and ADA compliance. All topographic, control, and right-of-way survey efforts will be led by Mark Thomas’ in- house land surveyors. Our understanding of the limits of topographic survey are generally identified below: x Fred Waring Drive – Approximately 1000’ west and east of the Washington Street intersection. x Washington Street – From the northerly Southwest Community Church driveway entrance just south of Fred Waring Drive to the Las Brisas South intersection. x Supplemental topography along the landscaping/retention basin facility adjacent to the public sidewalk on both the northwest and southwest quadrants of the Fred Waring Drive/Washington Street intersection. The following research efforts will be performed by our Team prior to commencement of any field surveying activities: x Secure a minimum of three (3) California Spatial Reference Network (CSRN) published primary control data sheets within the greater project area to tie results to the North American Datum of 1983 (NAD83), California State Plane Coordinate System Zone 6. x Secure vertical benchmark data sheets located within the general project area from the County of Riverside and the Cities of La Quinta, Palm Desert, and Indian Wells to tie results to the North American Vertical Datum of 1988 (NAVD88). x Perform as necessary research with the local Cities to obtain centerline monument ties. x Secure available parcel/tract/records of survey/corner records/record mapping from Riverside County to identify all local control/cadaster. x Secure as-built information and pertinent records from both Riverside County and the City of Indian Wells for the existing 24” storm drain facility. Additionally, secure roadway as-built facilities from Riverside County and the Cities of La Quinta, Palm Desert, and Indian Wells. Deliverables: Data collection inventory matrix, field review notes, and photos Task 4.2 Control Survey - Upon completion of all research efforts, our Team will deploy field crews to perform a Control Survey using both conventional and GPS based survey methods. Field surveying efforts will include location of CSRN primary control stations, local centerline monuments/property corners necessary to retrace/re-establish rights of way and street centerlines, and vertical benchmarks. Our Team will compile all data and generate a Project Control Base Survey Map illustrating found data, field notes, and vertical/horizontal datums to be utilized for the project. This map will be utilized for the basis of all survey control efforts as part of this project and will support future construction staking efforts. Deliverables: Project Control Survey Base Map in PDF and AutoCAD formats Task 4.3 Design Topography - Due to the level of detail and accuracy needed for design level topography, our Team will perform ground survey using conventional methods to locate all hardscape, drainage features, utility facilities, break lines, driveways, and other pertinent improvements. Supplemental ground survey efforts will include cross sections at 50-foot intervals and at midpoints of driveway approaches along Washington Street and Fred Waring Drive within the limits identified previously. Additionally, it is understood the retention basin, parking lot adjacent to the two driveway entrances northwest PProfessional Engineering Services for Washington Street at Fred Waring Drive Triple Left Turn Lanes – Project 2017-01 Page | 16 of the intersection, and sloped areas within the vacant lands northeast of the intersection will require supplemental spot elevations. It is assumed the property owners/City will provide sufficient access to support these efforts. Lastly, our Team will hand dig two areas adjacent to the perimeter wall between the Palm Royale Country Club/Fred Waring Drive to provide spot elevations of the top of footing to review for potential daylighting in the proposed condition. The design survey data will be downloaded, processed and tied to the horizontal and vertical control established for the project. Our Team will generate a Topographic Survey Base Map at 1” = 40’ scale. Mapped features will generally include edge of pavement/curb and gutter/sidewalk, driveways, landscape features such as monument signs/irrigation control valves/significant vegetation, manholes, drop inlets, walls, signs, utility/light/signal poles, above ground utility service facilities, storm drain facilities, and other visible improvements at the surface elevation. Break lines will be collected along all mapped improvements listed above to create continuous contours with a 1.0’ interval and a Digital Terrain Model (DTM). Deliverables: Topographic Survey Base Map in PDF and AutoCAD formats plotted at a 1”=40’ scale Digital Terrain Model (DTM) in electronic format Task 4.4 Existing Right-of-Way - In addition to research efforts identified in Section 4.1 above, our Team will secure preliminary title reports for the privately-owned landscaped home owner’s association parcels northwest of the intersection (APNs 637-340-035, 068 & 069) and the Southwest Community Church parcel (APN: 633-350-015). Our Team will analyze the title reports, record mapping, and found project control to establish existing street centerlines, rights of way, and property lines of record using industry accepted boundary retracement practices. All resolved linework will be illustrated in an Existing Right of Way Base Map (Land Net) depicting found local monuments/cadaster, pertinent notes on means/methods of retracement efforts, assessor’s parcel numbers, ownership of record, and measured bearings/distances. The Existing Right- of-Way Base Map (Land Net) will serve as the basis in identification of property interests (R/W, Temporary Construction Permits/Rights of Entry, etc.) necessary to construct the project. Based upon preliminary research, it appears much of this area was surveyed recently with sufficient record documents illustrating material location and disposition of key centerline/right of way monuments within our project limits and our assumption is a Record of Survey filed with the County of Riverside per the requirements of Section 8762 of the California Land Surveyor’s Act (Business and Professions Code §§ 8700 – 8805) is not required. Should field conditions dictate otherwise, Mark Thomas will notify the City with a recommended action plan/additional cost. Deliverables: Up to two (2) Preliminary Title Reports; Existing Right of Way Base Map (Land Net) in PDF/AutoCAD formats Task 5 Plans, Specifications, and Estimate - Based on our assessment of the proposed improvements and associated details, we have determined this project will require approximately 24 plan sheets for the Washington Street/Fred Waring Drive intersection improvements. The following table provides a breakdown of the number of sheets, the types of plans, plan scale, and number of sheets per project intersection. All plans will be signed and sealed by a California registered Civil Engineer.

The majority of the project site and buffer is developed; however, a portion overlaps native habitat in particular at the northeast corner of Washington Street and Fred Waring Drive. The project is within the Coachella Valley Multiple Species Habitat Conservation Plan and is outside of MSHCP conservation areas. The project is also a covered activity under the MSHCP; therefore, impacts to species covered by the MSHCP would be covered through consistency with the MSHCP and payment of applicable fees. Our subconsultant will conduct an assessment of biological resources that may occur within or adjacent to (within 500 feet) the proposed project. We will conduct a literature review to identify the potential for special- status species that are known to occur or may potentially occur near the site. Following the literature review, we will conduct a general survey of the project site and a 500-foot buffer where accessible (study area), to identify existing biological resources and potential biological constraints. Deliverables: Biological Survey (OPTIONAL) Task 5.9 Utility Potholing (OPTIONAL) – The ADVANTEC Team, through our sub-consultant, AZTEC Engineering will perform the utility potholing (if necessary) to determine if there are any utility conflicts at locations where new traffic signal pole foundations are proposed to be installed (4 locations). The final locations will be determined after the layout of our base mapping, utilities, and proposed traffic signal pole locations. If there are any apparent utility conflicts or locations that are subject to question, these will be the priority locations for potholing. Once the locations are determined, they will be submitted to the City for their review and approval.
