COAST HIGHWAY TRIP GENERATION ASSESSMENT Dear Mr. Hamid Kianipur: The firm of Urban Crossroads, Inc. is pleased to submit this Trip Generation Assessment for the gasoline/service station located at 2201 E. Coast Highway in the City of Newport Beach (see Exhibit 1). PROJECT DESCRIPTION It is our understanding that existing vehicle repair facilities on‐site will be modified to accommodate 2,215 square feet (sf) of convenience market, while the existing eight vehicle fueling positions (vfp) will remain. Access to the project site is provided via two existing right‐in and right‐out (RIRO) driveways at East Coast Highway and one existing RIRO driveway at Avocado Avenue. These three existing access points to the project are not anticipated to change with the proposed Project modifications. ALTERNATIVE TRIP GENERATION DESCRIPTORS Trip generation represents the amount of traffic which is both attracted to and produced by a development. Determining trip generation for a specific project is based upon estimates of the amount of traffic that is expected to be both attracted to and produced by the specific on‐site land uses. For this assessment, trip generation rates are based upon data collected by the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition, 2017. The Project will retain the existing vehicle fueling positions, and the existing service building will be modified to provide a convenience market/storage/office building. The following ITE Land Use (LU) Codes and land use descriptions associated with gas station uses have been considered to identify the appropriate ITE description for the existing facility and the modified project: 1. ITE Land Use Code: 944 ‐ Gasoline/Service Station This land use includes gasoline/service stations where the primary business is the fueling of motor vehicles. The sites included generally have a small building (less than 2,000 gross sf) that houses a cashier and limited space for motor vehicle maintenance supplies and general convenience products, as well as ancillary facilities for servicing and repairing motor vehicles. 2 2201 E. Coast Highway Trip Generation Assessment EXHIBIT 1: PROJECT SITE (EXISTING) 12730 -01 -study area.dwg Mr. Hamid Kianipur UNOCAL‐CDM July 12, 2019 12730‐02 ‐ TG Evaluation Ltr.docx 2. ITE Land Use Code: 945 ‐ Gasoline/Service Station with Convenience Market This land use includes gasoline/service stations with convenience markets where the primary business is still the fueling of motor vehicles. Some commonly sold convenience items are newspapers, coffee or other beverages, and snack items that are usually consumed in the car. The gross floor area of the convenience market is between 2,000 and 3,000 gross sf for sites included in this land use category. 3. ITE Land Use Code : 960 ‐ Super Convenience Market/Gas Station This land use includes gasoline/service stations with convenience markets where there is significant business related to the sale of convenience items and the fueling of motor vehicles. The gross floor area of the convenience market is at least 3,000 gross sf for sites included in this land use category. For the existing facility, ITE LU Code 944 (Gasoline/Service Station) is the appropriate land use since the existing building is 1,700 sf and ITE LU Code 944 are based on a building facility less than 2,000 sf. Similar to ITE LU Code 944, the existing building offers a limited space for motor vehicle maintenance/general convenience products and provides an ancillary facility for servicing and repairing motor vehicles. For the modified Project, ITE LU Code 945 (Gasoline/Service Station with Convenience Market) is the appropriate land use since the total square footage for the proposed building expansion is 2,150 sf and ITE LU Code 945 are based on convenience markets between 2,000 sf and 3,000 sf. ITE LU Code 960 (Super Convenience Market/Gas Station) are based on a higher square footage (at least 3,000 sf convenience market). Therefore, ITE LU Code 945 is utilized to estimate the new traffic generated by the proposed building expansion Project. NEW TRAFFIC IN COMPARISON TO PASS‐BY ACTIVITY Pass‐by trips are defined as intermediate stops on the way from an origin to a primary trip destination without a route diversion. Pass‐by trips are attracted from traffic passing the site on an adjacent street or roadway that offers direct access to the generator. These types of trips are typically associated with retail uses such as fast‐food restaurants, gas station, and banks with drive‐through windows just to name a few. As the existing and modified Project includes a gas station, pass‐by percentages have been obtained from the ITE Trip Generation Handbook, 3rd Edition, September 2017 for the applicable land uses. The ITE pass by percentages for each land use are provided below:  ITE LU Code 944 (Gasoline/Service Station): AM = 58% & PM = 42%  ITE LU Code 945 (Gasoline/Service Station with Convenience Market): AM = 62% & PM = 56% For the purpose of this trip generation assessment, the lowest pass‐by percentage of 42% is utilized for both land uses to provide a conservatively high primary trip estimate. Primary trips are associated with the specific purpose of visiting the Project site. The trip typically goes from an origin to a destination and then returns to the origin. 3 Mr. Hamid Kianipur UNOCAL‐CDM July 12, 2019 12730‐02 ‐ TG Evaluation Ltr.docx PROPOSED PROJECT TRIP GENERATION CHARACTERISTICS As mentioned previously, the trips generated by the Project’s change in land use have been estimated based on trip generation rates from the Institute of Transportation Engineers (ITE) publication Trip Generation (10th Edition, 2017). The trip generation rates used to estimate the existing and modified Project traffic are shown in Table 1.

Since the modified project is anticipated to add less than 300 new trips associated with the project building expansion (without or with pass‐by adjustment), a TPO analysis for the Project is not required. CONCLUSIONS Based on this assessment, the 2201 E. Coast Highway modified Project does not generate significant changes in the amount of trips generated for daily and peak hour conditions, in comparison to existing land use.

The sites included generally have a small building (less than 2,000 gross square feet) that houses a cashier and limited space for motor vehicle maintenance supplies and general convenience products. A gasoline/service station may also have ancillary facilities for servicing and repairing motor vehicles and may have a car wash. Convenience market with gasoline pumps (Land Use 853), gasoline/service station with convenience market (Land Use 945), and truck stop (Land Use 950) are related uses. Additional Data The independent variable-vehicle fueling positions-is defined as the maximum number of vehicles that can be fueled simultaneously. Gasoline/service stations in this land use include "pay-at-the-pump" and traditional fueling stations. Time-of-day distribution data for this land use for a weekday, Saturday, and Sunday are presented in Appendix A. For the 16 general urban/suburban sites with data, the overall highest vehicle volumes during the AM and PM on a weekday were counted between 11 :45 a.m. and 12:45 p.m. and 5:45 and 6:45 p.m., respectively. For the one center city core site with data, the overall highest vehicle volumes during the AM and PM on a weekday were counted between 10:30 a.m. and 11 :30 p.m. and 5:00 and 6:00 p.m., respectively. The sites were surveyed in the 1980s, the 1990s, the 2000s, and the 201 Os in Alberta (CAN), California, Florida, Kentucky, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, Ontario (CAN), Oregon, South Dakota, Texas, and Washington . Specialized Land Use Data A2006 study provided data on four private fuel facilities in Florida (source 721). These facilities provide self-fuel service, but are not open for use by the general public. To use the services offered at the facility, a pre-established membership account is required. The trip generation characteristics of this site differed from sites included in this land use; therefore, trip generation information for this site is presented here and was excluded from the data plots. The sites had an average of nine vehicle fueling positions. An average of 12 vehicle trips were counted during the weekday, AM peak hour of adjacent traffic and seven were counted during the weekday, PM peak hour of adjacent street traffic.

These service stations may also have ancillary facilities for servicing and repairing motor vehicles and may have a car wash. Some commonly sold convenience items are newspapers, coffee or other beverages, and snack items that are usually consumed in the car. The sites included in this land use category have the following two specific characteristics: • The gross floor area of the convenience market is between 2,000 and 3,000 gross square feet • The number of vehicle fueling positions is at least 10 Convenience market (Land Use 851 ), convenience market with gasoline pumps (Land Use 853), gasoline/service station (Land Use 944), truck stop (Land Use 950), and super convenience markeU gas station (Land Use 960) are related uses. Additional Data The independent variable, vehicle fueling positions, is defined as the maximum number of vehicles that can be fueled simultaneously. Gasoline/service stations in this land use include "pay-at-the-pump" and traditional fueling stations. Time-of-day distribution data for this land use are presented in Appendix A. For the five general urban/suburban sites with data, the overall highest vehicle volumes during the AM and PM on a weekday were counted between 7:30 and 8:30 a.m. and 3:45 and 4:45 p.m., respectively. A multi-variable regression analysis based on both the convenience market gross floor area (GFA) and the number of vehicle fueling positions (VFP) produced a series of fitted curve equations. The equations are in the form of: Vehicle Trips= [(VFP Factor) x (Number of VFP)] + ((GFA Factor) x (GFA)] + (Constant) The values for the VFP factor, GFA factor, and constant are presented in the following table for each time period for which a fitted curve equation could produce an R2 value of at least 0.50.
