The site is currently entitled to a maximum of 6,000 sf of medical office. The project, through a new Specific Plan, will plan for 100% medical office use. The project also includes construction of a parking structure. The Project site located at 6183-6185 Paseo Del Norte, south and west of Paseo Del Norte an'd Camino Del Parque in the city of Carlsbad. The Project will be served by an existing full-access unsignalized driveway to Paseo Del Norte. The Project study area includes eight (8) intersections and five (5) street segments. The transportation analyses for the Project were conducted in accordance with the City of Carlsbad Transportation Impact Analysis Guidelines. The following scenarios are evaluated in this report: • Existing • Existing + Project • Existing+ Cumulative • Existing + Cumulative + Project The gross Project trip generation was calculated using SANDAG's Not So Brief Guide of Vehicular Traffic Generation Rates for the San Diego Region (April 2002). Net trip generation was calculated by deducting trips associated with the existing on-site standard commercial office uses. The net Project trips are calculated to be 2,219 daily trips with 15 net AM peak hour trips (-8 inbound / 23 outbound) and 215 PM peak hour trips (84 inbound I 131 outbound). This report evaluated the effect of the Project on the Existing and Existing + Cumulative baselines using the two distinct analyses needed to meet requirements for both the City of Carlsbad Growth Management and the California Environmental Quality Act (CEQA). A multi-modal level of service (MMLOS) was also conducted for Paseo Del Norte and Camino Del Parque based on City guidelines. Based on City of Carlsbad criteria, one (l)no significant Project impact§ -i:s-are calculated due to the Praject adding traffic to a street segment that is exempt from LOS standards. However, the Project adds in excess of 110 ADT and 11 peak hour trips to segments of Palomar Airport Road that are exempt from LOS standards. Per City guidelinesConseguently. the Project will be required to prepare a Transportation Demand Management (TDM) plan and implement Transportation System Management (TSM) strategies as mitigation. No significant Project impacts were determined via regional SANTEC/ITE significance criteria LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 3-19-3089 Carlsbad Corporate Plaza Parking Structure '1:13089'Rcport\3089 Report doc, -.. -.. .. ... .. .. - -.. - .. - • - -• .. -.. • .. • - TABLE OF CONTENTS SECTION PAGE 1.0 Introduction ................................................................................................................................ 1 1.1 Project Description .............................................................................................................. 1 1.2 Project Impact Analyses ..................................................................................................... 1 2.0 Analysis Approach & Methodology .........................................................................................

The two existing buildings total 79,969 in gross floor area and the site is currently entitled to a maximum of 6,000 sf of medical office. The Project, through a Specific Plan, will plan for 100% medical office use. The Project site is located south and west of Paseo Del Norte and Camino Del Parque at 6183-6185 Paseo Del Norte. Paseo Del Norte is a generally north-south connector street. The major east-west arterial roadways to the north and south of the Project site are Palomar Airport Road and Poinsettia Lane, both providing regional access to Interstate 5. Figure 1-1 shows the vicinity map. Figure 1-2 shows a more detailed Project area map. Figure 1-3 shows the Project site plan. 1.2 Project Impact Analyses Two distinct analyses are needed to meet requirements for City of Carlsbad Growth Management and the California Environmental Quality Act (CEQA). Both analyses are included in this traffic impact analysis. The Growth Management Plan analysis is based on the City of Carlsbad Transportation(fie Impact Analysis Guidelines, which outlines evaluation of facilities based on their typologies, and it defines analysis methodologies, thresholds of significance, and other necessary considerations. Roadway segment analysis, signalized intersection analysis (queuing at tum lanes), and multimodal level of service (LOS) are included in this portion of the report. The CEOA Analysis is based on the Carlsbad historic use of thresholds of significance in the SANTECIITE Guidelines for Traffic Impact Studies in the San Diego Region, March 2000. Facilities are evaluated based on Table l of the SANTECIITE Guidelines. For roadway segments analysis capacity is evaluated using the City of Carlsbad Roadway Capacity Tables (same analysis as is required for Gro1Nth Management). Intersection LOS is evaluated based on the most recent version of the Highway Capacity Manual (HCM) methodology. No multi-modal analysis is required for this portion of the report.

Each of these approaches evaluates components of the street system, but using different methodologies. The following is a discussion of these methodologies. 2.1 Auto Analysis per City TIA Guidelines (Growth Management Plan) The following summarizes the evaluation methodologies to be used per the City of Carlsbad Transportation Impact Analysis Guidelines, consistent with the City's adopted Growth Management Plan. 2.1.1 Study Area Per the City of Carlsbad TIA Guidelines, the study area shall include the following: Intersections • All signalized intersections within 0.25 miles of a project access point serving vehicles will be included in the study area. Additional intersections within 0.25 to 0.5 miles from the project access points may also be added to the study area the discretion of the City Engineer / City Traffic Engineer. ■ Unsignalized intersections located along corridors subject to Auto MMLOS within the project study area may require a traffic signal warrant analysis. A warrant analysis is required if: o The unsignalized intersection provides direct access to the project site, or o The unsignalized intersection provides direct access to a cumulative project considered in the Transportation Impact Analysis o The unsignalized intersection has been identified by the City as a potential signalized intersection . A warrant analysis is not required for right turn in/right turn out only intersections or driveways that are physically restricted by a raised center median. Street Segments • Non-freeway roadway segments that are subject to Auto MMLOS Criteria and expected to experience an increase in project traffic equal to 50 or more peak hour trips in either direction of travel. Freeway Mainline Segments • Freeway mainline segments where the project adds 50 or more peak hour trips in either direction of travel. Freeway Ramps ■ Freeway entrance and exit ramps where the proposed project will add 20 or more peak- hour trips and/or cause any traffic queues to exceed ramp storage capacities . LINSCOTT, LAW & GREENSPAN, engineers 5 LLG Ref. 3-19-3089 Carlsbad Corporate Plaza Parking Structure N :\3089\Report\3089 Report.docx Based on these guidelines, the following auto faci lities are included in the study area for Growth Management Plan analysis: Intersections • Palomar Airport Road I Paseo Del Norte (signalized) • Paseo Del Norte I Main Project Driveway (unsignali zed) 2.1.2 Signalized Intersection Methodology The City of Carlsbad's published TIA Guidelines state that all signalized intersections within the study area are subject to the signalized intersection analysis. The analysis will address the adequacy of the signalized intersection geometry to serve the existing, forecast and project traffic through the intersection. As stated previously, all signalized intersection within 0.25 miles of the project auto access driveway or intersection shall be evaluated if the project adds trips to the left tum or right turning movements at the intersection. The signalized study area will be based on trip generation and trip assignment for the project. Analyses will be based on the following criteria: • Left turn queue assessment: Compare the left tum volume with the length of the left tum pocket(s ). A general rule of thumb of one foot per left turning vehicle per lane may be used for this analysis. • Left turn volume: If the left tum volume exceeds 250 vehicles per hour, a second left tum lane is recommended. • Right turn volume: If the right tum volume exceeds 150 vehicles per hour, a dedicated right tum lane is recommended. 2.1.3 Roadway Segment Level of Service Methodology The City of Carlsbad's published TIA Guidelines state that roadways within the Project study area subj ect to Auto MMLOS standards shall be evaluated using the most current version of the Highway Capacity Manual, as outlined in the City's General Plan Mobility Element (2015). Roadway Capacity Tables derived from the Highway Capacity Manual were developed specifically for each roadway subject to MMLOS in the City of Carlsbad. The specific capacity calculated for each roadway takes into account key geometric and operational factors including number of lanes, type of facility, intersection cycle length, distance between intersections, and other factors related to lane capacity and signal operations. The capacity fo r each roadway segment was calculated using the ARTPLAN software, which was developed using the capacity calculations outlined in the HCM. The ARTPLAN software package is used nationally as a planning tool, but alternative methods can be used to calculate roadway segment capacity. The City of Carlsbad Segment LOS Capacity Threshold table provides the directional capacity for each roadway segment subject to vehicular level of serviceMMLOS analysis in the General Plan Mobility Element. To evaluate the operating conditions along a study corridor, peak hour volumes are compared to the Roadway Capacity Tables to determine the segment operating conditions. The LOS for each segment is reported for all study scenarios in the TIA.

Based on the Project's trip generation and distribution (Section 4.0), the following locations are included in the Project study area for CEQA Analysis: Intersections • Palomar Airport Road / I-5 Southbound Ramps (signalized) • Palomar Airport Road / I-5 Northbound Ramps (signalized) • Palomar Airport Road / Paseo Del Norte (signalized) • Paseo Del Norte / Project Driveway (unsignalized) • Paseo Del Norte / Camino De Las Ondas (signalized) • Poinsettia Lane / I-5 Southbound Ramps (signalized) • Poinsettia Lane / I-5 Northbound Ramps (signalized) • Poinsettia Lane / Paseo Del Norte (signalized) Street Segments Palomar Airport Road • I-5 to Paseo Del Norte Paseo Del Norte • Palomar Airport Road to Project Driveway • Project Driveway to Camino De Las Ondas • Camino De Las Ondas to Poinsettia Lane Poinsettia Lane • I-5 to Paseo Del Norte Ramp Meters ■ Palomar Airport Road to I-5 Northbound • Poinsettia Lane to I-5 Southbound LINSCOTT, LAW & GREENSPAN, engineers 7 LLG Ref. 3-19-3089 Carlsbad Corporate Plaza Parking Structure N )089\Repon\3089 Repon.docx - 41 .. -.. - -... - - -• -- --... • 2.2.2 Signalized Intersection Methodology Signalized intersections were analyzed under AM and PM peak hour conditions. Average vehicle delay was determined utilizing the methodology found in Chapter 19 of the Highway Capacity Manual 6th Edition (HCM 6), with the assistance of the Synchro 10 computer software. The delay values (represented in seconds) are presented for the pre-and-post Project conditions. A more detailed explanation of the methodology is attached in Appendix B. 2.2.3 Unsignalized Intersection Methodology Unsignalized intersections were analyzed under AM and PM peak hour conditions. Average vehicle delay was determined based upon the procedures found in Chapter 20 and Chapter 21 of the HCM 6 with the assistance of the Synchro 10 computer software. A more detailed explanation of the methodology is also attached in Appendix B. 2.2.4 Roadway Segment Methodology The City of Carlsbad has historically evaluated street segment LOS by evaluating the volume-to- capacity ratio for peak hour traffic . The City has updated the capacity table utilized for the "Volume/Capacity", or "V/C" method with development of the recent City of Carlsbad Segment LOS Capacity Threshold table also utilized in the Growth Management Plan roadway LOS methodology described above in Section 2.1.3. 2.2.5 Metered Freeway Ramps The measure of effectiveness (MOE) for the metered freeway ramp analysis is delay in minutes. Ramp meter flows characteristically vary throughout the peak hour based on the performance of the freeway mainline. As the mainline becomes more congested, the ramp meter rates decline, allowing fewer vehicles onto the freeway in the same time period. The metered on-ramps in the study area were analyzed using the Fixed Rate method. With the Fixed Rate method, using the most restrictive flow rate during the peak hour, the total discharge and delay (in minutes) are calculated and the corresponding queue lengths are calculated. The meter rates are dynamic, and fluctuate between the most conservative (restrictive) and most aggressive (permissive) intervals assigned to a metered ramp. The regional standard of practice is to use the longest, restrictive rates to ensure a conservative analysis. The metering information was obtained from Caltrans for the on-ramp and is included in Appendix A. 2.3 Multimodal Level of Service Analysis The City of Carlsbad requires multimodal level of service (MMLOS) evaluation for pedestrian, bicycle and transit/rideshare users of the public roadway system. The City organizes the street network by a system of "typologies", as defined by the City of Carlsbad Mobility Element. Depending on the typology, different streets may require different MMLOS evaluations.

Bicycle Accommodations --Available Mobility Services Source: City of Carlsbad Each roadway's typography is evaluated for the particular set of roadway users based on sub-criteria, which is assigned "typology points". The following represents examples of sub-criteria within the "Transit and Ridesharing" general criteria group with corresponding points assigned: • Access -"ADA compliant sidewalk or path to transit stops in both directions" (15 points assigned) • Connectivity-"Multiple transit routes on segment" (10 points assigned) • Transit Priority-"Dedicated right of way" (5 points assigned) • Service -"Commute shuttle service provided during the morning and afternoon commute periods" (10 points assigned) • Amenities -"Covered bus stops" (5 points assigned) • Bicycle Accommodations -"Bike parking available at the bus stop" (5 points assigned) • Available Mobility Services -"On demand rideshare services available" (10 points assigned) The MMLOS analysis evaluates each of the sub-criteria, totals the points for the subject street typology, and compares the points to the City's MMLOS Point System and LOS Rating, shown in Table 2-2. This table assigns a qualitative LOS to several ranges of points, similar to the application of LOS to ranges in delay for CEQA-analysis intersection operations.

It should be noted that scores in excess of 100 points can be achieved. 2.3.1 Multi-Modal Facilities to be Included in Study Area In general, multi-modal facilities must be included in the study area based on the following criteria: Pedestrian: • All pedestrian facilities that are directly connected to project access points will be included in the study area. • All pedestrian facilities adjacent to the project development site that provide direct pedestrian access to the project site will be included in the study area. • The analysis of each pedestrian facility will extend in each direction to the nearest intersection or connection point to a multiuse trail or path. The study area will extend from the project site until a Mobility Element Road or Class I trail is reached in each direction. • Pedestrian facilities shall include all existing and proposed sidewalks, crosswalks, signalized pedestrian phases, and ADA-compliant facilities. • Pedestrian analysis need only be conducted for the side of the street where the project is located, unless the project is located on both sides of the street, in which case both sides of the street should be studied. • Pedestrian analysis shall be conducted for all roadway segments included in the study area that are subject to the Pedestrian MMLOS standards. Bicycle: • All facilities that bicyclists can legally use shall be included in the study area from each project access point extending in each direction of travel to the nearest intersection, dedicated bicycle facility, or connection point to a multiuse trail or path. Inventory and evaluation shall include all off-street and on-street bicycle paths, lanes, and routes. • Bicycle analysis shall be conducted for both directions of travel ( e.g. both sides of the street) of each facility included in the study area. • Bicycle analysis shall be conducted for roadway segments subject to the Bicycle MMLOS standards. LINSCOTT, LAW & GREENSPAN, engineers 10 LLG Ref. 3-19-3089 Carlsbad Corporate Plaza Parking Structure N:\J089\RcponlJ0R9 Rcpon.doc, Transit: • All existing transit lines and transit stops within ½ mile walking distance of the project site shall be included in the study area. • If the roadways within the study area are not subject to Transit MM.LOS standards no further transit analysis is required. • For Aft-all transit lines located within ,4 mile walking distance of the praject sitethe study area, the nearest stop for each line in each direction of travel will be analyzed according to Transit MM.LOS. • All pedestrian routes linking the project site to a transit line within the ¼ mile walking distance boundary. • If no transit lines are provided, but the roadways within the study area are identified as subject to Transit MM.LOS, the project shall complete the worksheet for "No Transit Located within ½ Mile Walk from Subject Site or Roadway Segment". • Transportation Demand Management Measures shall be identified for the project, which may include on-demand transit, flex, or other measures. 2.3.2 Project Multi-Modal Study Area Based on the study area criteria shown m Section 2. 3. 1, the MM.LOS study area includes the fo llowing: Pedestrian Paseo Del Norte (Neighborhood Connector) • Paseo Del Norte to Project Site (southbound only) • Project Site to Caminita Madrigal (southbound only) Camino Del Parque (Local/Neighborhood Street) • Paseo Del Norte to Caminita Del Reposa (southbound only) Bicycle Paseo Del Norte (Neighborhood Connector) • Paseo Del Norte to Project Site (both directions) • Project Site to Caminita Madrigal (both directions) Camino Del Parque (Local/Neighborhood Street) • Paseo Del Norte to Caminita Del Reposa (both directions) There are no transit lines or stops within ½ mile walking distance of the Project site.

Maintain LOS D or better for all modes that are subject to this multi-modal level of service (MMLOS) standard, as identified in Table 3-1 of the General Plan Mobility Element, excluding LOS exempt intersections and streets approved by the City Council. Thus, the Growth Management Plan's standard for all non-exempt street system facilities is LOS D. To comply with the Growth Management Program, all roadway facilities identified as not meeting the performance standard (LOS D) in the existing conditions scenario must be fully mitigated regardless of the project impact to that facility, or the TIA must request an exemption from the LOS D standard according to the Mobility Element Implementing Policy 3-P.9. The project causes a significant impact to the transportation facility in the study area if one or more of the following criteria is met: • The roadway facility is projected to exceed the LOS D standard and the project's traffic meets or exceeds the thresholds of significance listed in Table 2-3; or • A ramp meter delay exceeds 15 minutes and the project's traffic meets or exceeds the thresholds of significance listed in Table 2-3; or • The addition of project results in a change in LOS from acceptable (LOS D or better) to deficient (LOS E or F) on a roadway segment, freeway segment or ramp; or • The project results in a change in conditions on a roadway segment, freeway segment or ramp that exceeds the allowable thresholds ( outlined in Table 2-3) for locations operating at a deficient LOS without the project (baseline conditions).

Cumulative impacts may be mitigated through fair share contribution. Projects identified for fair share contribution should be included in the City's Capital Improvement Program (CIP) or Transportation Impact Fee (TIF) program. Any roadway section that is identified as having a significant impact must either: • Mitigate the traffic impact to pre-project conditions, or • Request LOS exemption from City Council for the LOS standard and identify feasible TSM & TDM mitigation measures. Because of the qualitative nature of the MMLOS methodology, a project impact is significant if an existing pedestrian, bicycle or transit facility is determined to not meet the LOS D standard regardless of the forecasted number of project trips expected to use the facility. An impact occurs and is deemed significant if: • An existing facility in the project study area does not meet the pedestrian, bicycle or transit LOS standard, or • The project causes a standard facility to become substandard (e.g., removal of an existing bike lane or bus stop, or blocking pedestrian access), or • A gap is identified in or directly adjacent to the study area related to pedestrian, bicycle or transit service to the project site.

The defined thresholds shown in Table 2-4 below for freeway segments, roadway segments, intersections, and ramp meter facilities are based on published San Diego Traffic Engineers' Council (SANTEC) guidelines. If the project exceeds the thresholds in Table 2-4, then the project may be considered to have a significant project impact. A feasible mitigation measure will need to be identified to return the impact within the thresholds (pre-project + allowable increase) or the impact will be considered significant and unmitigated. TABLE 2-4 TRAFFIC IMPACT SIGNIFICANT THRESHOLDS Allowable Increase Due to Project Impactsb Level of Service with Freeways Roadway Segments Intersections Ramp Metering Project" Speed Speed Delay Delay V/C (mph) V/C (mph) (sec.) (min.) D,E&F ( or ramp meter delays O.ol 1 0.02 1 2 2c above 15 minutes) Footnotes: a. All level of service measurements are based upon HCM procedures for peak-hour conditions. However, V/C ratios for Roadway Segments may be estimated on an ADT/24-hour traffic volume basis (using Table 2 or a similar LOS chart for each jurisdiction). The acceptable LOS for freeways, roadways, and intersections is generally "D" ("C" for undeveloped or not densely developed locations per jurisdiction definitions). For metered freeway ramps, LOS does not apply. However, ramp meter delays above 15 minutes are considered excessive. b. If a proposed project's traffic causes the values shown in the table to be exceeded, the impacts are deemed to be significant. These impact changes may be measured from appropriate computer programs or expanded manual spreadsheets. The project applicant shall then identify feasible mitigations (within the Traffic Impact Study [TIS] report) that will maintain the traffic facility at an acceptable LOS. If the LOS with the proposed project becomes unacceptable (see note a above), or if the project adds a significant amount of peak hour trips to cause any traffic queues to exceed on-or off-ramp storage capacities, the project applicant shall be responsible for mitigating significant impact changes. c. The impact is only considered significant if the total delay exceeds 15 minutes. General Notes: 1. V /C = Volume to Capacity Ratio 2. Speed = Arterial speed measured in miles per hour 3. Delay = Average stopped delay per vehicle measured in seconds for intersections, or minutes for ramp meters. 4.

The gross square footage is used in the trip generation calculations. The site is currently entitled to and operates 6,000 gross sf of medical office use, with the remainder occupied by standard commercial office. The Project thus proposes the repurposing of 73,969 sf within the two existing buildings from standard commercial office use to medical office use. Trip generation estimates for the Project were based on the SANDAG's Brief Guide of Vehicular Traffic Generation Rates for the San Diego Region (April 2002). Table 4-1 tabulates the Project traffic generation.The gross project site (before accounting for existing land use) is calculated to generate 3,998 ADT with 240 total AM peak hour trips and 440 total PM peak hour trips. After accounting for the existing medical office on-site and the existing commercial office to be removed, the net Project is calculated to generate 2,219 ADT, with 15 AM (-8 inbound / 23 outbound) peak hour and 215 PM (84 inbound / 131 outbound) peak hour trips. The Project reduces the number of inbound trips in the AM peak hour compared to existing conditions.

In coordination with the City, the following SHt--eleven (ell) cumulative projects that may be built and occupied by Project opening day were identified for inclusion in Near- Term conditions. Table 5-1 lists and describes each cumulative project and Figure 5-1 depicts the cumulative project locations. Figure 5-2 shows the total cumulative projects AM/PM peak hour traffic volumes. Figure 5-3 shows the AM/PM peak hour traffic volumes for the "Existing + Cumulative" scenario. Figure 5-4 shows the peak hour traffic volumes for the "Existing + Cumulative + Project" scenario. 5.2 Network Conditions There are several planned improvements that will be constructed at the intersection of Palomar Airport Road and Paseo Del Norte. These include addition of an eastbound right-tum bay, modification of the eastbound left-tum lanes to provide additional storage, conversion of one of two existing southbound through lanes to a right-tum lane, and right-tum overlap phasing. Figure 5-5 depicts Near-Term street network conditions. The Poinsettia 61 project will also complete a missing portion of Poinsettia Lane between Cassia Road and El Camino Real. Based on the traffic impact analysis completed for this project (October 2016), completing this gap in the street network would redistribute traffic in the vicinity. The effects of this redistribution are expected to be largely localized, affecting Cassia Road, El Camino Real immediately north and south of Poinsettia Lane, and Poinsettia Lane east of Ambrosia Lane. The effects are not expected to extend to the Project study area intersections on Poinsettia Lane, approximately two miles west of the Poinsettia 61 project. There are no k.n0\¥1'1 pending improvements to the study area street network or to nearby facilities that would notably affect conditions in the srudy area. No impro>,•ements or ehanges to the study area street faeilities are assumed for ~~ear Term (Existing =I-Cumulative) eonditions.

The Project will not add 50 or more peak hour trips to any street subject to vehicular level of service. Significance of impacts is based on the City's TIA Guidelines, as discussed in Section 2.4.1. 6.2 Analysis of Existing Conditions Table 6-1 shows the queue lengths under Existing conditions at study area signalized intersections, for the applicable left-and-right turning movements to which the Project would contribute traffic. As shown in Table 6-1, existing queues are accommodated in the existing turn pockets. Double left tum lanes are currently provided for each of the signalized left-tum movements the Project contributes traffic to at Palomar Airport Road / Paseo Del Norte. Dedicated turn pockets are currently not provided for the right-tum movements the Project will add traffic to. The sigF1ali2ed right turn movements the Prajeet eontributes traffie to at Palomar Airport Road / Paseo Del Norte are both equal to or greater than 150 trips in eaeh peak hour under Existing eonditions and therefure dedieated right turn lanes may be eonsidered per City TIA Guidelines (see Seelim~ 2.1.2). 6.3 Analysis of Existing + Project Conditions Table 6-1 shows the queue lengths under Existing + Project conditions at study area intersections, for the applicable left-and-right turning movements with the Project's traffic contribution As shown in Table 6-1, existing + project queues are accommodated in the existing tum pockets. The volume of left-tum traffic at the signalized left-tum movements the Project contributes traffic to at Palomar Airport Road I Paseo Del Norte exceeds 250 trips with the addition of Project traffic. However, double left tum lanes are currently provided for each of these movements and the calculated queues can be accommodated in the provided turn pockets. The Project contributes traffic to two right-tum movements with volumes exceeding 150 peak hour trips that do not currently have a dedicated right-tum lane. There is a capital improvement project to add a right-tum bay to eastbound Palomar Airport Road at Paseo Del Norte. The tum lane will be 250 feet long. Construction of this improvement is expected in March 2020, prior to the Project's opening day, and is assumed complete in near-term conditions (see Section 5.2). The addition of a northbound right-tum lane on Paseo Del Norte at Palomar Airport Road is not feasible due to constrained right-of-way.The signali2ed right turn movements the Prajeet eontributes traffie to at Palomar l\irport Road / Paseo Del Norte are both equal to or greater than 150 trips in LINSCOTT, LAW & GREENSPAN, engineers 34 LLG Ref. 3-19-3089 Carlsbad Corporate Plaza Parking Structure I\ 1089 Repon.JOSQ Rcpon.don each peak hour under Existing conditions and therefore dedicated right tum lanes may be considered per City TIA Guidelines (see Scetio,"z 2.1.2).

The MMLOS study area was selected based on the City's scoping requirements and the street typology of the roadway, which indicates which modes are subject to LOS standards on that facility type. Table 6-3 summarizes the MMLOS analysis results for the pedestrian and bicycle facilities on Paseo Del Norte and Camino Del Parque. As shown in Table 6-3 these facilities achieve acceptable LOS G D or better. Appendix E contains the detailed MMLOS worksheets.

The threshold for requiring TDM/TSM measures is 110 ADT or 11 peak hour trips added to an exempt street segment. The Project will add in excess of 110 ADT / 11 peak hour trips to Palomar Airport Road, which is exempt from LOS standards between I-5 and College Boulevard, and is thus required to implement TDM/TSM measures. Additionally, the City of Carlsbad passed a TDM ordinance to establish policies and guidelines for transportation demand management in the city. The ordinance supports the Climate Action Plan and seeks to reduce the number of Carlsbad employees driving alone to and from work and increase alternative commuting options like transit, biking, carpool, and vanpool to meet 2035 greenhouse gas reduction targets. The TDM ordinance requires new nonresidential development where the employees generate a minimum of 110 average daily trips to develop a Transportation Demand Management Plan. The Project will also generate at least 110 employee ADT. 6.7.1 Transportation Demand Management (TDM) To meet the TDM requirements of the TDM Ordinance and Mobility Element policy, the Project shall prepare a Tier 3 TDM Plan to the satisfaction of the City Engineer. Typical TDM plans consist of programs and policies to reduce the demand for the single occupant automobile. Common techniques include carpool programs, car-sharing and bike-sharing programs, flexible work hours, telecommute provisions, shuttle services to nearby transit stations, employee transit subsidies (e.g. employers will subsidize bus or rail tickets), installation of bicycle facilities (lockers, racks, lanes, showers at employment areas, etc.), or other measures that would reduce the demand to drive, particularly during the peak commute hours. The Carlsbad TDM Handbook provides a point value for these strategies corresponding to their effectiveness in shifting travel away from single-occupant vehicles. A Tier 3 TDM plan, required for the Project and prepared under separate cover, includes the following elements: existing conditions and context, three (3) required TDM strategies, a selection of infrastructure improvements and programmatic strategies, and adherence to monitoring and reporting requirements. The Project will provide the following measures to meet the Tier 3 TDM requirements: Infrastructure ■ Public bike parking ■ Bicycle repair station ■ Micromobility parking ■ Preferential parking for car/vanpools ■ Parking spaces for carshare vehicles ■ Passenger loading zone.

No communication upgrades or electrical work outside of the existing cabinet will be within the scope of this work. 6.8 TIA Guidelines -Findings and Conclusions Based on the City's TIA Guidelines and thresholds of significance, presented in Section 2.4.1, the following findings and conclusions are noted. The Project adds in excess of 11 peak hour trips to Palomar Airport Road, which has been classified as exempt from Auto LOS standards due to failing street segment Levels of Service. As such, the Project mitigation in the form of is required to implement Transportation Demand Management (TDM) and Transportation Systems Management (TSM) measures are required regardless of the Project's impact to the facility, based on Section 8.1 of the City of Carlsbad Transportation Impact Analysis Guidelines and Mobility Element policy 3-P .11 . The Carlsbad TDM Ordinance also compels preparation of a TDM plan for the Project based on the number of employee trips it is expected to generate. To satisfy these requirements, the Project will prepare a Tier 3 TDM _plan, under separate cover, and contribute toward the installation of a new traffic signal controller at the intersection of Palomar Airport Road and Paseo Del Norte. All turning movements evaluated at Palomar Airport Road / Paseo Del Norte and the Project's driveway to Paseo Del Norte indicate that existing and future queueing with the addition of Project traffic can be accommodated in existing tum pockets. Double left tum lanes are currently provided on all approaches to the Palomar Airport Road / Paseo Del Norte intersection. Per City TIA Guidelines, dedicated right tum lanes may be considered for the two right-tum movements the Project will add traffic to at the Palomar Airport Road / Paseo Del Norte intersection, the eastbound right and the northbound right, as the Existing baseline traffic volumes exceed 150 trips in both the AM and PM peak hours. A pending capital improvement project will construct an eastbound right-tum lane on Palomar Airport Road, among other improvements, and is assumed built in this analysis beginning in near-term cumulative conditions. Due to right-of-way constraints, a northbound right-tum on Paseo Del Norte is not feasible.However, based on a focused evaluation of the Palomar Airport Road / Paseo Del Norte intersection, dedicated right tum lanes a-re ultimately not recommended, for the follo,wing reasons: LINSCOTT, I.AW & GREENSPAN, engineers 40 LLG Ref. 3-19-3089 Carlsbad Corporate Plaza Parking Structure N:130891Rcpon\308Q Rcpon.doc, Baseline Yolumes exceed the 150 peak hour 'rehicle threshold by a ~odest ~ount that may be ·.vithin the typical range of fluctuation observed in traffic counts at any g1¥en location.

LINSCOTT, LAW & GREENSPAN, engineers 54 LLG Ref. 3-I 9-3089 Carlsbad Corporate Plaza Parking Structure N: 1089 Repon\308Q Ropon.doc, 8.0 CONCLUSIONS The following is a brief summary of the analysis results per City TIA Guidelines (Growth Management Plan) and SANTEC/ITE Guidelines (CEQA). 8.1 TIA Guidelines -Findings and Conclusions Based on the City's TIA Guidelines and thresholds of significance, presented in Section 2.4.1, the following findings and conclusions are noted. The Project adds in excess of 11 peak hour trips to Palomar Airport Road, which has been classified as exempt from Auto LOS standards due to failing street segment Levels of Service. As such, the Project mitigation in the form of is required to implement Transportation Demand Management (TDM) and Transportation Systems Management (TSM) measures are required regardless of the Project's impact to the facility, based on Section 8.1 of the City of Carlsbad Transportation Impact Analysis Guidelines and Mobility Element policy 3-P.1 l. The Carlsbad TDM Ordinance also compels preparation of a TOM plan for the Project based on the number of employee trips it is expected to generate. To satisfy these req uirements. the Project will prepare a Tier 3 TDM plan, under separate cover. and contribute toward the installation of a new traffic signal controller at the intersection of Palomar Airport Road and Paseo Del Norte. All turning movements evaluated at Palomar Airport Road I Paseo Del Norte and the Project's driveway to Paseo Del Norte indicate that existing and future queueing with the addition of Project traffic can be accommodated in existing tum pockets. Double left tum lanes are currently provided on all approaches to the Palomar Airport Road / Paseo Del Norte intersection. Per City TIA Guidelines, dedicated right tum lanes may be considered for the two right-tum movements the Project will add traffic to at the Palomar Airport Road I Paseo Del Norte intersection, the eastbound right and the northbound right, as the Existing baseline traffic volumes exceed 150 trips in both the AM and PM peak hours. A pending capital improvement project will construct an eastbound right-tum lane on Palomar Airport Road, among other improvements, and is assumed built in this analysis beginning in near-term cumulative conditi ons. Due to right-of-way constraints. a northbound right-tum lane on Paseo Del Norte is not feasible.Howe¥er, based on a focused e¥aluation of the Palomar Airport Road / Paseo Del Norte intersection, dedicated right turn lanes are ultimately not recommended, for the fo llowing reasons: • Baseline •,rolumes e~rneed the 150 peak hour Yehicle threshold by a modest amount that may be within the typical range of fluctuation observed in traffic counts at any giYen location. • The intersection is calculated to operate at acceptable LOS Dor better during peak hours (see SeelioH 7, SANTEC/ITE analysis) and no significant Project impacts or mitigation are identified on that basis. • Palomar Airport Road between I 5 and College Boule:vard has been classified as eKempt from Yehicle LOS standards. This determination means that the City >.viii not implement 'rehicular impro:vements beyond what is identified as appropriate at build out of the General Plan because acquiring the rights of 'Nay is not feasible and/or the proposed improYements would result in unacceptable impacts to other community :values or General Plan policies. The Project will contribute to TDM/fSM measures to improYe mobil ity in the corridor.
