The project at Lots 21 and 22 is planned to supply 426 parking spaces in between the surface parking and the parking structure. This building would be connected to the existing lonis campus through a new pedestrian bridge across Whiptail Loop. This pedestrian bridge will be constructed as part of the project. Currently, the lonis Pharmaceuticals campus supports a total of 240,038 SF of gross floor area (GFA) that consists of 170,838 SF of Headquarters/ Scientific Research and Development use and 69,200 SF of Conference Center use. The lonis Pharmaceuticals campus supports amenity spaces (i.e. fitness center, basketball/badminton court, and a one-half basketball court), which serve the on-site population and do not generate the need for additional parking. The lonis Pharmaceuticals site is planning to conduct the renovation of a 10,893 SF portion of the Conference Center's building area, of which 8,847 SF will be converted from existing conferencing space into new private offices and open office space and the remaining 2,446 SF will be converted to additional storage space.

One of the planned driveways {western driveway) will be constructed as the north leg of the intersection of Gazelle Court at Whiptail Loop E. / Whiptail Loop W. serving primarily as access to surface-level parking west of the new building and access towards the parking structure. The other driveway (eastern driveway) will be located approximately 250 feet east of the intersection serving primarily as the access towards the pick-up/drop-off zone south of the new building, surface-level parking east of the new building, and access towards the parking structure. 2.1 Conformance with the Carlsbad Oaks North Specific Plan Environmental Impact Report The Carlsbad Oaks North Specific Plan (Carlsbad Oaks N.) Environmental Impact Report (EIR) evaluated the potential environmental effects of an industrial park on approximately 414 acres ("Overall Project") using the California Environmental Quality Act (CEQA) criteria of vehicular delay and Level of Service (LOS) as evaluated at the time of the Carlsbad Oaks N. EIR. Conformance to the Carlsbad Oaks N. EIR consists of the proposed project (lot 3 within the Carlsbad Oaks North Specific Plan) traffic not exceeding what was analyzed in the Carlsbad Oaks N. EIR, and therefore not resulting in additional transportation impacts under CEQA. The Carlsbad Oaks N. EIR evaluated an overall project with 22,650 Average Daily Trips {ADT), 2,375 AM peak hour trips (2,100 inbound and 275 outbound), and 2,670 PM peak hour trips (590 inbound and 2,080 outbound) based on SAN DAG trip rates.

The threshold of significance for the implementation of TOM and TSM strategies per City guidelines is established at 110 average daily trips (ADT) or 11 peak-hour trips to LOS-exempt roadways. To demonstrate the project's compliance with the City's Mobility Element Policy 3-P.11, a trip distribution representing the distribution of project traffic is included in Figure 4-1. The project is calculated to generate 1,319 ADTs, 211 AM peak hour trips (190 In/ 21 Out), and 185 PM peak hour trips (18 In / 166 Out). Considering the thresholds of significance described above and the project's trip generation, any LOS-exempt roadway segment where at least 8.3% of project ADT (110 ADT out of 1,319 project ADTs) or 5.8% of peak hour trips (11 peak hour trips out of 190 peak hour trips for the AM peak inbound direction) would trigger the requirements established within the City's Mobility Element Policy 3-P.ll. , -."-,.

This level of analysis is characterized by the requirement to evaluate several modes of transportation, including automobile, pedestrian, bicycle, and transit facilities. The level of analysis required for roadways by mode is based on a street type standard referred to as typology (as identified in the City's General Plan Mobility Element Table 3-1), which identifies the uniqueness of a roadway based on surrounding land uses and defines which modes of travel should be accommodated on a roadway. This approach is aimed towards those roadways that connect to the project site and to the citywide transportation system and the location of the project such that roadways are analyzed using a multi-modal level of service (MM LOS) approach. An MMLOS analysis provides a qualitative "grade" assigned to travel modes, ranging from the level of service (LOS) A to LOS F, with LOS A reflecting a high service standard and LOS F reflecting a poor service standard. The City's General Plan established a standard of LOS Dor better only for the travel mode(s) subject to the MM LOS standard for the designated roadway typology. The City has developed a detailed MM LOS Tool to aid in MMLOS analysis methodology. The three (3) roadways connecting to the project site are listed below: • Gazelle Ct. (Whiptail loop E. / Whiptail Loop W. -southern terminus) • Whiptail Loop W. (Faraday Ave. -Gazelle Ct./ Whiptail Loop E.) • Whiptail loop E.

The primary purpose is to connect people to businesses within the City's industrial parks, B. Designed to safely move all modes of travel while efficiently moving vehicles and buses from arterial streets and employment/transit connector streets to businesses, C. Traffic calming devices are generally discouraged given the propensity for larger trucks and heavy vehicles in this area, D. On-street parking may be provided as long as it does not interfere with the turning radii of heavy vehicles. Industrial-type roadways are identified within the City's General Plan Mobility Element Table 3-1 to be required to be analyzed from an automobile and transit standpoint. Figure 4-4 shows the identified study roadway segments including the street typology and a summary of their attributes, consistent with the City's General Plan Mobility Element. The following is a brief description of the required transit MM LOS methodology for this project and the criteria outlined in the City's MM LOS Tool: • Transit MMLOS for transit priority streets, the MMLOS criteria evaluates the transit vehicle right-of-way (e.g., dedicated or shared, signal priority), hours and frequency of service (e.g., weekday/weekend hours, peak period highway); performance (e.g., on-time or late); amenities and safety (e.g., lighting, covered stop, bench, on-board bike/surfboard storage); and connectivity (e.g., to other transit routes, employment areas, schools, visitor attractions, and other major destinations).

The queuing at the study intersection in the AM and PM peak hours was analyzed using a software package extension of Synchro 10 called Sim Traffic, which is an application of the Highway Capacity Manual methodology. Additionally, a simplification of the project access driveways was implemented by analyzing the two (2) planned driveways as one (1) single driveway. This single driveway was modeled as the future north leg of the intersection of Gazelle Court at Whiptail Loop E. / Whiptail Loop W. Traffic count data for the intersection of Gazelle Court at Whiptail Loop E. / Whiptail Loop W. was obtained from counts collected on Wednesday, November 2nd, 2022. The traffic count data was collected during a mid-week day and while schools were in session. Refer to Appendix C for the peak hour traffic count data.

According to the CAMUTCD (2014, rev 6), the following guidance governs the installation of stop signs: "Engineering judgment should be used to establish intersection control. The following factors should be considered: A. Vehicular, bicycle, and pedestrian traffic volumes on all approaches; B. Number and angle of approaches; C. Approach speeds; D. Sight distance available on each approach; and E. Reported crash experience. YIELD or STOP signs should be used at an intersection if one or more of the following conditions exist: A. An intersection of a less important road with a main road where application of the normal right-of-way rule would not be expected to provide reasonable compliance with the law; B. A street entering a designated through highway or street; and/or C. An unsignalized intersection in a signalized area."

This guidance is provided to enhance safety and reduce the risk of rear-end accident potential when a multi-way stop sign application is not warranted. Below is an evaluation of criteria A through D listed in this section of the CAMUTCD. Criteria: A. An interim measure is not justified as a traffic control signal is not planned -NOT MET B. A review of accident data from 2016 through 2021 (SWITRS data) shows there have not been five or more reported crashes in a 12-month period that are susceptible to correction by a multi-way stop application -NOT MET C. In evaluating Whiptail Loop at Gazelle Court, SAN DAG data and traffic counts obtained for the project (refer to Figure 5-1) were consulted to evaluate the likelihood of exceeding the volume criteria for an eight-hour period. Peak hour intersection data contained in Appendix C of the LMA shows that on the major street, less than 100 vehicles in both AM and PM peak hours on the major street (Whiptail Loop). This provides evidence that the vehicular volume (even at buildout) would exceed 300 vehicles per hour for any 8 hours on an average day. On the minor street, the highest peak hour showed 52 vehicles entering the intersection. This Is far short of the 200 units per hour for the same 8 hours. There were zero bicycles and pedestrians, which indicates the volumes are low and would not add significantly to the volume (i.e. "units") as mentioned in the CAMUTCD criteria. This indicates that the criteria is NOT MET. D. No single criteria is met. However, criteria B shows zero accident history susceptible to correction by a stop sign and therefore, Criteria D cannot be met at the 80% level-NOT MET. In addition, the optional criteria listed was explored to support any recommendations. This criterion is discussed below.

As a "t'' intersection, the turning volumes (shown in Figure 5·1) from the side street would not be compared to through movements. The left turns from the major street are not a significant proportion of the through movements during the peak hour with a maximum volume of 3 left turns during the AM peak hour. As a result of the relatively low volumes and the overall traffic pattern, there is no anticipated need to control the major street traffic to avoid conflicts. This criterion is NOT MET. B. As noted above, there are no high pedestrian generators in the vicinity leading to this criterion being NOT MET. C. There are no noted sight distance obstructions. Therefore, this criterion is NOT MET. D. The intersection would not qualify as an intersection of two residential neighborhood collector streets of similar design and operating characteristics. This criterion is NOT MET. As a result of the evaluation discussed above, an all-way stop control is not warranted at this location. ..

To establish a baseline for Horizon Year 2050 volumes, the SANDAG Traffic Information Forecast Center Series 14 volumes were first observed and compared between Year 2016, Year 2025, and Year 2050 for all of the roadway segments conforming the intersection legs of S. Melrose Avenue at Faraday Avenue. This procedure was conducted as a means to establish a growth rate between the TFIC models, which would be applied to the peak hour turning movements at the intersection based on the directionality of the movements and the intersection legs (roadway segments) corresponding to the direction of such movements. The roadway segments leading to the intersection of S. Melrose Avenue at Faraday Avenue were observed to result in a decrease in volume when directly compared between Year 2025 and Year 2050 TFIC models. Therefore, as a conservative approach, and to establish a Horizon Year baseline, a total growth rate of 10% was applied to Existing baseline peak hour volumes at the intersection. Figure 7-5 shows the Horizon Year 2050 AM and PM peak hour volumes of S. Melrose Drive at Faraday Avenue. Table 7-7 shows the Horizon Year 2050 intersection AM / PM Peak Hour LOS. As shown in the table, the study intersection is anticipated to operate at an acceptable LOS Dor better in both AM and PM peak-hour settings. . . URBAN SYSTEMS ASSOCIATES, INC. ·>~·})..

October 18, 2022 In order to determine consistency with the Carlsbad Oaks North Specific Plan, research was conducted to determine current status and anticipated buildout of each lot. This includes land use and intensity information taken from the previously mentioned "Carlsbad Oaks Business Park Transportation Impact Consistency Memo" (Attachment A). Based on this information, an updated trip generation tracking table was prepared and is provided below. According to this table, with development on Lots 21/22 as described above, the Carlsbad Oaks North Specific Plan area would remain 11,204 ADT under the original entitlement from the EIR. In addition, the Specific Plan area would remain 74 l trips under in the AM peak hour and 982 trips under in the PM peak hour. As the proposed development on Lots 21/22 would be less than what was planned in the original EIR and the zoning is consistent with the Specific Plan, the proposed project would be determined to be consistent with the Specific Plan. Trip Distribution A trip distribution figure has been prepared in response to the City of Carlsbad's requirement to evaluate the Jonis Pharmaceuticals Lot 21 and 22 project's consistency with the City's Mobility Element Policy 3-P. l l, which describes the "requirement to new development that adds vehicle traffic to street facilities that arc exempt from the vehicle level of service (LOS) standard ( consistent with 3-P .9) to implement Transportation Demand Management (TDM) strategies that reduce the reliance on sing;e-occupant automobile and assist in achieving the City's livable streets vision and Transportation System Management (TSM) strategies that improve traffic signal coordinaton and improve transit service." The threshold of significance for the implementation of TDM and TSM strategies per City guidelines is established at 110 average daily trips (ADT) or 11 peak hour trips to LOS exempt roadways. To demonstrate the project's compliance with the City's Mobility Element Policy 3-P.l l, a trip distribution representing the distribution of project traffic is included in Attachment B. The project is calculated to generate 1,319 ADTs, 211 AM peak hour trips (190 In/ 21 Out), and 185 PM peak hour trips (18 In/ 166 Out). Considering the thresholds of significance describe above and the project's trip generation, any LOS exempt roadway segment where at least 8.3% of project ADT (110 ADT out of 1,319 project ADTs) or 5.8% of peak 2 8451 Mirulani Drive, Suite A • San Diego, CA 92126 • (858) 560-4911 Jon Ohlson DGA ·© Urban Systems Associates, Inc. October 18, 2022 hour trips ( 11 peak hour trips out of 190 peak hour trips for the AM peak inbound direction) would trigger the requirements established within the City's Mobility Element Policy 3-P. l l. The project's trip distribution has been prepared applying engineering judgement to distribute project traffic in the surrounding roadway network. The project's distribution has been influenced by the presence of several major roadways in the vicinity of the project site, as well as the access to freeways (Interstate 5 and State Route 78), and residential areas. As shown in the project trip distribution figure, it is estimated that the project would add traffic exceeding the threshold of 110 ADT or 11 peak hour trips at the following locations: • S. Melrose Drive (between Lionshead Ave. -Palomar Airport Rd.) • El Camino Real (between Cannon Rd. -College Blvd.) As a result of the project's trip distribution and its effect related to the City's Mobility Element Policy 3-P.l l, the project will incorporate a TDM Plan and a fair-share payment towards the City of Carlsbad's a TSM program. 3 8451 Mira/ani Drive, Suite A • San Diego.

RE: Carlsbad Oaks Business Park Transportation Impact Consistency Memo MEMO The purpose of this memo is to compare the proposed project (Lot 3) trip generation and traffic against what was evaluated in the Carlsbad Oaks North Specific Plan Environmental Impact Report ("Carlsbad Oaks N. EIR") dated August 2002. The Carlsbad Oaks N. EIR evaluated potential environmental effects of an industrial park on approximately 414 acres ("Overall Project") using the California Environmental Quality Act (CEQA) criteria of vehicular delay and Level of Service (LOS) as evaluated at the time of the Carlsbad Oaks N. EIR. The CEQA analysis uses trip generation rates that provide a physical number of project vehicles based on land uses types and building size or usable acreage. Trip generation rates provide the ability to calculate a project's Average Daily Trips (ADT), AM Peak Hour trips, and PM Peak Hour trips. Trip rates are provided by the San Diego Association of Governments (SAN DAG). Roadway LOS is affected by the addition of traffic, which will typically increase vehicular delay and decrease LOS. If the proposed project (Lot 3) traffic does not exceed what was analyzed in the Carlsbad Oaks N. EIR, then the proposed project would not result in additional transportation impacts underCEQA. The Carlsbad Oaks N. EIR evaluated an overall project with 22,650 Average Daily Trips (ADT), 2,375 AM peak hour trips (2,100 inbound and 275 outbound), and 2,670 PM peak hour trips (590 inbound and 2,080 outbound) based on SANDAG trip rates. Excerpts from the EIR and an overall map are included in Attachment A. The proposed project (Lot 3) is located within the Carlsbad Oaks North Business Park and is calculated to generate 479 ADT, 78 AM peak hour trips (69 inbound and 9 outbound), and 79 PM peak hour trips (16 inbound and 63 outbound) based on SANDAG trip rates. Carlsbad Oaks North Business Park has 22 lots for development and several open space lots. Sixteen (16) of the lots have completed structures or uses. Table 1 shows a comparison of the Carlsbad Oaks N. EIR against the occupied lots and against the proposed project (Lot 3). Both comparisons (highlighted in grey) show how the Carlsbad Oaks N. EIR evaluated more traffic than the current uses including Lot 3. Therefore, the proposed project (Lot 3) traffic was included in the Carlsbad Oaks N. EIR and does not exceed the evaluated ADT, nor the AM and PM net totals. The AM Page 1 of 16 • LOS Engineering, Inc. Traffic and Transponation 11622 El Camino Real, Suite 100, San Diego, CA 92130 Phone 619-890-1253, E-mail: Justin@LOSengineering.com MEMO outbound does have a 6 peak hour trip outbound increase that is offset by a -1,036 inbound trip reduction resulting a net -1,030 AM peak hour trip reduction over the Carlsbad Oaks N. EIR. The completed portion of the Carlsbad Oak Business Park and Lot 3 is calculated to have a reduction in traffic as compared to the Carlsbad Oaks N. EIR by 55% less ADT, 40% less AM trips, and 44% less PM trips. The trip generation of existing development in the Carlsbad Oaks North Specific Plan plus the proposed project (Lot 3) are less than what was evaluated in the EIR; therefore, the proposed project (Lot 3) does not result in additional transportation impacts under CEQA. A majority of the Carlsbad Oaks North Business Park is served by Whiptail Loop Road, which does not provide a route for cut-through traffic. Therefore, a cordon count can provide an assessment of how much traffic the occupied lots are generating vs. the SAN DAG book rate as used in the Carlsbad Oaks N. EIR. Traffic data was collected on Thursday, June 2, 2022 on Whiptail Loop East and Whiptail Loop West (Attachment B). As shown in Table 2, the actual traffic counts were less than the forecasted traffic based on SANDAG trip rates for the lots with access from Whiptail Loop. This indicates that the Carlsbad Oaks N. EIR provided a conservative evaluation.
