average trip counts because it is permitted to have freeway signage identifying/advertising its location and use. No other car wash in Santa Ana is known to have such signage. RKE found that the Express Car Wash Trip Generation shown on page 3-82 and page 3-90 (Table 5-1) of the revised traffic study for the Car Wash Project should include a Saturday analysis because the proposed car wash will generate approximately 50% more trips during a Saturday than on a weekday. Likewise, for the Existing Plus Project and Future conditions analysis, a Saturday analysis needs to be evaluated, and tables 8-1 and 8-2 on pages 3-105 and 3-107, respectively, should include a Saturday analysis. Accordingly, RKE found the revised traffic study incomplete because it needs to include a Saturday traffic analysis for each of the different timeframes that are evaluated. Furthermore, the traffic study should utilize typical trip generation for an express car wash during those timeframes to fully evaluate whether the Car Wash Project will have a significant impact on traffic. Second, RKE found that a traffic safety analysis of the intersection of North Tustin Avenue at 4th Street is crucial and must be performed. (See Exhibit D, p. 5.) This particular intersection "has a significant amount of peak hour and daily traffic, and any increase in traffic generated by the proposed project could potentially increase the collision rate at this intersection." (Id.) RKE reviewed the collisions at the intersection and found "the collision rate is significantly higher than would be expected at this type of intersection." Specifically, "[t]he ten year average collision rate at this intersection is 0.37 collissions per million entering vehicles ... [and] the most recent collision rate during the past three years (2016-2018) the collision rate has increased to 0.43 collisions per million entering vehicles." (Id.) Significantly, RKE found that "any increase in traffic generated by the proposed [Russell Fischer Car Wash] [P]ooject could potentially increase the collission rate at this intersection." (Id. and Appendix B, S WITRS data for Intersection of N. Tustin Ave. and 4a' Street.) Third, the site plan for the Russell Fischer Car Wash Project that is shown on page 3-68 of the revised Traffic Study (Figure 2-2) includes a full driveway access on N. Tustin Avenue. This driveway is located approximately 240-feet from the intersection of Tustin Avenue at 4th Street. RKE found this distance to be too close for allowing the subject driveway to provide fall service access with all turning movements, since it would interfere with the northbound left turn pocket on Tustin Avenue. Accordingly, site plan modifications for the Russell Fischer Car Wash Project are necessary to include a fully operative, full service access driveway. Moreover, the revised traffic study provides no explanation on what the Car Wash Project "re-route" is for, as shown on page 3-73 and 3-74 (Figures 3- 2 and 3-3). RKE inquires what aspect of the Car Wash Project caused the re-route of traffic? Since the traffic entering and exiting the Project site is at an intersection that is already extremely congested and accident prone, this clarification is important to evaluate the impacts on traffic. On pages 3-86 and 3-87 of the revised traffic study (Figures 5-3 and 5-4), the Russel Fischer Car Wash Project volumes do not appear to match the Project net trip generation in Table 5-1, and the Trip Distributions on pages 3-84 and 3-85 (Figures 5-1 and 5-2). RKE found that it is unclear how the project only volumes were calculated, and inquired whether the traffic study included the full project trip 14 75A-24
