For the purposes of this analysis, East Street and South Street refer to the portions of South East Street and East South Street, respectively, in the immediate vicinity of the proposed project. In accordance with the scope of work, LSA has prepared this analysis consistent with the requirements of the City and with applicable provisions of the California Environmental Quality Act (CEQA). The purpose of this traffic impact analysis is to provide a focused analysis of the proposed project within the Colony District. Figure 1 shows the location of the project site. The traffic analysis for the proposed project examines six scenarios: 1. Existing conditions 2. Existing plus project conditions 3. Future (219) baseline conditions 4. Future (219) plus project conditions 5. General Plan buildout baseline conditions 6. General Plan buildout plus project conditions PROJECT DESCRIPTION The existing ac site is currently occupied by two businesses located at 711 East Street and 633 East Street. The two sites are accessed by separate unsignalized full-access driveways onto East Street. One business performs screen printing and the other is an automobile storage lot that auctions vehicles to dealerships. Auctions occur Mondays at 6: p.m. and Fridays at 12: p.m. The proposed project will demolish the existing uses and construct 42 townhome dwelling units. The two existing driveways will be consolidated into one unsignalized full-access driveway on East Street. This driveway is further analyzed in the Access Analysis section of this report. A site plan of the proposed project is illustrated on Figure 2. METHODOLOGY The study area analyzed in this report includes the following intersections: 1. East Street/Santa Ana Street 2. East Street/South Street Additionally, this report analyzes the effects to roadway average daily traffic (ADT) on East Street between Santa Ana Street and South Street. Figure 1 illustrates the locations of the intersections included in the study area. P:\OLC164\TIA 3.docx «4/5/17» 1

Traffix (Version 8.) and Synchro 9.1 are the software applications utilized to determine the levels of service (LOS) for signalized and unsignalized intersections, respectively. These programs calculate LOS based on traffic volume and intersection geometry inputs. The ICU methodology compares the amount of traffic an intersection is able to process (capacity) to the level of traffic during peak hours (volume). The resulting volume-to-capacity (v/c) ratio is expressed in terms of LOS. The HCM 21 methodology calculates the delay experienced by all movements through an intersection. At a two-way, stop-controlled intersection (i.e., unsignalized intersections where the main street is uncontrolled and the minor street has to stop before finding a gap to enter the main street), delay is reported for the most delayed approach. LOS criteria for intersections are presented below. LOS Descriptions. LOS is a qualitative assessment of the quantitative effects of such factors as traffic volume, roadway geometrics, speed, delay, and maneuverability on roadway and intersection operations. LOS is assigned along the following letter gradient where LOS A represents free-flow activity, and LOS F represents overcapacity operation: LOS A: No approach phase is fully utilized by traffic, and no vehicle waits longer than one red indication. Typically, the approach appears quite open, turns are made easily, and nearly all drivers find freedom of operation. LOS B: This service level represents stable operation, where an occasional approach phase is fully utilized, and a substantial number are nearing full use. Many drivers begin to feel restricted within platoons of vehicles. LOS C: This level still represents stable operating conditions. Occasionally, drivers may have to wait through more than one red signal indication, and backups may develop behind turning vehicles. Most drivers feel somewhat restricted, but not objectionably so. LOS D: This level encompasses a zone of increasing restriction approaching instability at the intersection. Delays to approaching vehicles may be substantial during short peaks within the peak period; however, enough cycles with lower demand occur to permit periodic clearance of developing queues, thus preventing excessive backups. LOS E: Capacity occurs at the upper end of this service level. It represents the most vehicles that any particular intersection approach can accommodate. Full utilization of every signal cycle is attained no matter how great the demand. LOS F: This level describes forced-flow operations at low speeds, where volumes exceed capacity. These conditions usually result from queues of vehicles backing up from a restriction downstream. Speeds are reduced substantially, and stoppages may occur for short or long periods of time due to the congestion. In the extreme case, speed can drop to zero. P:\OLC164\TIA 3.docx «4/5/17» 4

HCM = Highway Capacity Manual ICU = intersection capacity utilization The City s guidelines specify the use of a saturation flow rate of 1,7 vehicles per lane per hour and a clearance interval factor of 5 percent. These have been applied in the analysis of all signalized study area intersections. Roadway Segment Level of Service Methodology Using the same v/c methodology discussed above, daily roadway link v/c ratios were determined using roadway volume data and the theoretical daily capacities determined by the Circulation Element of the Orange County General Plan. Existing and future roadway volumes are based on volume data collected via pneumatic tube along East Street on Tuesday, December 2, 216. The theoretical daily capacity of a roadway is dependent on roadway classification, as shown in the table below. Type of Arterial Daily Capacity Eight Lanes Divided 75, Six Lanes Divided 56,3 Four Lanes Divided 37,5 Four Lanes (Undivided) 25, Two Lanes (Undivided) 12,5 Source: Orange County General Plan, Circulation Element, Table IV-2B. For roadway segments, the City General Plan establishes a target of LOS C. If a segment is found to operate at LOS D, E, or F under daily conditions, its operation is also analyzed under peak-hour conditions. If the roadway segment also operates at LOS D, E, or F under peak-hour conditions and project traffic increases the daily v/c ratio by.1 or greater, then the project is determined to have a significant impact. The relationship between LOS and the v/c ratio for roadways is shown in the following table. P:\OLC164\TIA 3.docx «4/5/17» 5

The Final V/C Ratio includes the future v/c ratio at an intersection, considering traffic from existing conditions, ambient growth, approved/related projects, and the proposed project but without any proposed mitigation. Mitigation is required for any intersection where project traffic is considered to have a significant impact.

V/C = volume-to-capacity EXISTING CONDITION Existing Circulation System Key roadways in the vicinity of the proposed project are as follows: East Street: East Street is a north-south roadway located east of and adjacent to the project site and is classified as a Secondary Arterial by the City s General Plan Circulation Element. East Street is a four-lane roadway divided by a two-way left-turn (TWLT) lane that acts as a median. East Street provides direct access to the project site and therefore facilitates all of the trips generated by the project. The posted speed limit on East Street is 35 miles per hour (mph). There are sidewalks provided on both sides of the street. There are no bike lanes, and on-street parking is not permitted. South Street: South Street is an east-west roadway located south of the project site and is classified as a Collector Street by the City s General Plan Circulation Element. It is a two-lane, undivided roadway. The posted speed limit on South Street is 35 mph. There are sidewalks on both sides of the street, and on-street parking is permitted. Bike lanes are not provided. Santa Ana Street: Santa Ana Street is an east-west roadway located north of the project site and is classified as a Collector Street by the City s General Plan Circulation Element. It is a two-lane undivided roadway. The posted speed limit on Santa Ana Street is 35 mph. There are sidewalks on both sides of the street, and on-street parking is permitted. Bike lanes are not provided. P:\OLC164\TIA 3.docx «4/5/17» 6

LSA confirmed schools were in session with typical hours prior to scheduling data collection. Peak-hour intersection turn volumes were surveyed on a typical weekday (Tuesday, December 2, 216) at the two study area intersections. These volumes were taken in 15-minute increments and then totaled as hourly volumes, which is the standard procedure for volume data collection. Figure 3 presents the existing a.m. and p.m. peak-hour turn movement volumes for the study area intersections as determined by this method. The traffic volume data sheets are provided in Appendix A. Table A summarizes the results of the existing a.m. and p.m. peak-hour LOS analysis for the two study area intersections. All ICU analysis worksheets are provided in Appendix B. As Table A indicates, all study area intersections operate at an acceptable LOS (i.e., LOS D or better) in the a.m. and p.m. peak hours.

With a roadway capacity of 37,5 ADT, this roadway segment operates with a v/c ratio of.36. The study area roadway segment operates at a satisfactory LOS A in the existing condition. FUTURE (219) BASELINE CONDITION The proposed project is anticipated to be completed by 219. LSA did not identify any approved or pending projects in the vicinity of the proposed project that would have the potential to add measurable traffic to the study intersections. In order to account for ambient traffic growth in future year baseline traffic volumes, existing roadway and intersection volumes were escalated 1 percent per year, for a total of 2 percent over the next 2 years. Future (219) Baseline Intersection Level of Service Analysis Intersection geometrics at the study area intersections are not anticipated to change by the project opening year. The future a.m. and p.m. peak-hour traffic volumes are shown on Figure 4.

As this table indicates, all study area intersections operate at an acceptable LOS in the a.m. and p.m. peak hours in the future (219) baseline condition. Future (219) Baseline Roadway Segment Level of Service Analysis Existing roadway traffic volume was also escalated by 2 percent to account for regional traffic growth. The projected future daily volume along East Street between Santa Ana Street and South Street is 13,823 ADT. With a capacity of 37,5 ADT, this roadway segment operates with a v/c ratio of.37. The study area roadway segment operates at a satisfactory LOS A in the future (219) baseline condition. GENERAL PLAN BUILDOUT BASELINE CONDITION The City analyzed the conversion of this property to residential with the certified Housing Opportunities Rezoning Project (Supplemental Environmental Impact Report [SEIR] 346). At that time, a density of 18 dwelling units per acre (32 dwelling units) was analyzed. The City of Anaheim Housing Opportunities Rezoning Project SEIR 346 Technical Traffic Study (Iteris, July 213) included the intersection of East Street/South Street in the analysis. This data forms the baseline for analysis of the proposed project, which increases the number of dwelling units to 42. General Plan Buildout Baseline Intersection Level of Service Analysis Intersection geometrics at the study area intersections are anticipated to change slightly in the General Plan buildout. The southbound and northbound approaches at East Street/South Street currently have one right-turn, one through, and one left-turn movement for each approach. According to the General Plan, the right-turn only lane will become a shared through-right lane on both approaches. The General Plan buildout a.m. and p.m. peak-hour traffic volumes from the Housing Opportunities Rezoning Project SEIR 346 Technical Traffic Study are shown on Figure 5. Table C summarizes the results of the future a.m. and p.m. peak-hour LOS analysis for all study area intersections. As Table C indicates, all study area intersections operate at an acceptable LOS in the a.m. and p.m. peak hours in the General Plan buildout baseline condition. General Plan Buildout Baseline Roadway Segment Level of Service Analysis The City of Anaheim Housing Opportunities Rezoning Project SEIR 346 Technical Traffic Study (Iteris, July 213) did not analyze daily traffic conditions along East Street or South Street.

The General Plan buildout intersection turn movement volumes disclosed in SEIR 346 indicate a p.m. peak-hour volume of 2,3 vehicles along East Street. By applying an industry standard factor (i.e., 1 percent of daily traffic occurs during the p.m. peak hour), the General Plan buildout daily volume along East Street between Santa Ana Street and South Street is estimated at 2,3 ADT. With a capacity of 37,5 ADT, this roadway segment operates with a v/c ratio of.54. The study area roadway segment operates at a satisfactory LOS A in the General Plan buildout baseline condition. PROJECT IMPACTS Trip Generation As stated previously, the project site is currently occupied by two businesses: one performs screen printing, and the other is an automobile storage lot that auctions vehicles to dealerships. Auctions occur Mondays at 6: p.m. and Fridays at 12: p.m. Neither business is easily placed into an Institute of Transportation Engineers (ITE) Trip Generation category. In order to calculate existing trip generation, LSA contracted with an independent data collection company to obtain driveway volumes in the p.m. peak hour on Monday, December 19, 216 (auction day) and in a.m. and p.m. peak hours the following Tuesday, December 2, 216 (typical weekday) for 711 East Street (Driveway 1) and 633 East Street (Driveway 2). Given the potential for parking intrusion into the nearby residential neighborhood, pedestrian traffic into 633 East Street was also noted. For the purposes of determining the trip generation for the existing sites, the typical weekday volumes were used. However, it should be noted that the survey during the auction period on Monday showed a slightly higher volume of vehicles along with pedestrian volumes from vehicles parked in a nearby residential neighborhood. According to the driveway vehicular volumes, the combined volume of the two driveways (i.e., existing trip generation) was 16 a.m. peak-hour trips (11 inbound and 5 outbound), and 33 p.m. peakhour trips (9 inbound and 24 outbound) on a typical weekday. The trip generation potential of the proposed project was calculated using a trip generation rate for townhomes found in the ITE Trip Generation, Ninth Edition (212). The trip generation comparison for the proposed project is summarized in Table D. As Table D indicates, the proposed project is anticipated to generate 244 daily trips, 19 a.m. peak-hour trips (3 inbound and 16 outbound), and 22 P:\OLC164\TIA 3.docx «4/5/17» 12

ADT = average daily traffic DU = dwelling units p.m. peak-hour trips (15 inbound and 7 outbound). With the project, there are 3 additional a.m. peakhour trips and 11 fewer p.m. peak-hour trips than the existing condition. Trip Distribution and Assignment The potential routes from the project (north to Lincoln Avenue, east to State College Boulevard, south to Ball Road, and west to Harbor Boulevard) appear to have relatively equal utility. Therefore, LSA distributed project trips equally in all directions with east-west movements assigned to South Street. Figure 6 illustrates the net project trip distribution and the a.m. and p.m. peak-hour trip assignment volumes. EXISTING PLUS PROJECT CONDITION The net project trips were added to the existing traffic volumes at the study area intersections and roadway segments. Figure 7 shows the resulting existing plus project a.m. and p.m. peak-hour traffic volumes. Existing Plus Project Intersection Level of Service Analysis Table E summarizes the results of the existing plus project a.m. and p.m. peak-hour LOS analysis for all study area intersections. As Table E indicates, all study area intersections are anticipated to operate at an acceptable LOS (i.e., LOS D or better) in the a.m. and p.m. peak hours with implementation of the proposed project. Based on the City s criteria for determining significant traffic impacts (as described in the Methodology section of this report), the proposed project is not expected to result in a significant impact at any of the study area intersections.

The study area roadway segment will continue to operate at a satisfactory LOS A in the future (219) plus project condition. According to this analysis, the study area roadway segments operate at a satisfactory LOS with the addition of the project. GENERAL PLAN BUILDOUT PLUS PROJECT CONDITION As mentioned above, the General Plan buildout baseline scenario is based on the data from the City s SEIR 346, where the conversion of the property to residential land use has already been analyzed. The 32 dwelling units previously analyzed are less than the currently proposed 42 dwelling units. In order to add the project to the General Plan buildout scenario, the trip generation for the additional 1 units has been calculated using rates from ITE Trip Generation and is included in Table G.

Figure 9 illustrates the net project trip distribution and the a.m. and p.m. peak-hour trip assignment volumes. The resulting project trip assignments were overlaid onto the General Plan baseline to determine the General Plan plus project traffic volume and LOS at the study intersections.

With a capacity of 37,5 ADT, this roadway segment operates with a v/c ratio of.54. The study area roadway segment will continue to operate at a satisfactory LOS A in the General Plan buildout plus project condition. Based on the City s criteria for determining significant traffic impacts (as described in the Methodology section of this report), the proposed project is not expected to result in a significant impact at any of the study area intersections or roadway segments. ACCESS ANALYSIS As discussed in the project description, the project will consolidate the two existing driveways on East Street into one unsignalized full-access driveway. In order to assess the operation of the driveway, LSA used northbound and southbound roadway volumes collected by pneumatic tube and anticipated project turn volumes to calculate peak-hour LOS at the proposed project driveway. On Tuesday, December 2, 216, the a.m. peak hour occurred at 7:15 a.m., and the p.m. peak hour occurred at 4:15 p.m. Because the proposed project driveway will be unsignalized, LSA calculated delay and LOS using HCM 21 methodology. Analysis of the unsignalized driveway has been conducted for the proposed driveway using northbound and southbound roadway volumes collected by pneumatic tube along East Street and anticipated project turn volumes. All HCM worksheets have been attached in Appendix C. According to this analysis, the project driveway is expected to operate at a satisfactory LOS with 12.1 seconds of delay (LOS B) in the a.m. peak hour and 1.6 seconds of delay (LOS B) in the p.m. peak hour. CONCLUSION Based on the results of this traffic impact analysis, the proposed 42 townhome dwelling units can be implemented without significantly impacting the circulation system. All study area intersections are anticipated to operate at a satisfactory LOS in both a.m. and p.m. peak hours with the addition of project traffic. LSA also examined the project access driveway and determined that the project can be expected to function adequately without interference to the arterial street system.
