DEVELOPMENT IDENTIFICATION Gibson Traffic Consultants (GTC) has been retained to analyze the traffic impacts of the proposed expansion of Scott's Bar & Grill quality restaurant. GTC is a professional traffic engineering consulting firm registered and licensed in the State of Washington. This study has been organized in the manner of the SEPA Traffic Impact Requirements for the City of Edmonds for developments generating less than 25 PM peak -hour trips. GTC is located at: 2802 Wetmore Avenue, Suite 220 Everett, WA 98201 Phone: 425-339-8266 Fax: 425-258-2922 Email: info@gibsontraffic.com Matthew Palmer, responsible for this report and traffic analysis, is a licensed professional engineer (Civil) in the State of Washington and member of the Washington State section of ITE. The proposed Scott's Bar & Grill expansion will consist of adding additional outside seating area to the existing restaurant located on the north side of 244th Street SW (Lake Ballinger Way). The address is: 8115 Lake Ballinger Way Edmonds, WA 98026 Scott's Bar & Grill is requesting permits for an additional outside seating area consisting of a 1,025 square feet. The proposed expansion is anticipated to be operational in 2011. The property currently is served by the signalized intersection of Aurora Village Shop Center Street at Lake Ballinger Way. No change in access is proposed. Gibson Traffic Consultants December 2010 GTC 410-137 1 Scott's Bar & Grill Trip Generation &Mitigation Memorandum 2. TRIP GENERATION Quality Restaurant (Land Use: 931) was utilized for the trip generation of the expansion as the land use description best matches Scott's Bar & Grill: full-service eating establishments with typical turnover rates of at least one hour or longer, usually requires reservations, and generally not part of a chain. Whereas the High -Turnover (Sit -Down) Restaurant (Land Use: 932) typically has turnover rates of approximately one hour or less, frequently belongs to a restaurant chain, and typically does not take reservations. Trip generation rates were obtained from Trip Generation, O' Edition (2008) by the Institute of Transportation Engineers (ITE). The average trip generation rates for ITE Land Use Code 931, Quality Restaurant have been used for the trip generation calculations. The ITE Trip Generation Handbook, 2"d Edition (2004) documents the pass -by reduction for a quality restaurant at 44 percent. This pass -by reduction has been applied to the daily, AM peak -hour and PM peak -hour trip generation calculations. The trip generation land use descriptions, rate sheets, and pass -by sheets have been included in the attachments. The outdoor seating expansion of Scott's Bar & Grill is anticipated to generate 52 net new ADT, with 1 net new AM peak -hour trips (0 inbound/1 outbound) and 5 net new PM peak -hour trips (3 inbound/2 outbound). The trip generation is summarized in Table 1. Table 1.

'TRAFFIC IMPACT FEES Traffic impact rnitigation payments to the City of Edmonds are based on Edinonds Road Impact dee Rate Stucty'-fable 4, Impact Fee Rates. The table does not have a rate for quality restaurant; therefore, GTC has performed an independent fee calculation in accordance with ECDC 1 &81130, The traffic impact -fee is based on the net new PM peak -hour trips anticipated to be generated by the development, a mitigation fee of $1,04-9.41 per PM peak -hour trip and an estimated trip length factor. In calculating the independent fee calculation the trip length from the City of Edmonds Tr af ,fie Iny)act Analysis Requireinents, 2009-In7pact Fee Rate Table for 14nd use Restaurant: sit-down was utilized for the quality restaurant.

Scott's Bar & Grill. outside seating area expansion is anticipated to generate 5 PM peak -hour trips per Table 1, which results in 3,65 PM peak -hour trips when multiplied by the trip length adjustment factor. Based on a mitigation fee of $1,049.41 per PM peak -hour trip and an estimated trip length factor the traffic mitigation fees for the expansion are $3,830.35.

Quality restaurants generally do not serve breakfast; some do not serve lunch; all serve dinner. This type of restaurant usually requires reservations and is generally not part of a chain. Patrons commonly wait to be seated, are served by a waiter/waitress, order from menus and pay for meals after they eat. While some of the study sites have lounge or bar facilities (serving alcoholic beverages), they are ancillary to the restaurant. High -turnover (sit-down) restaurant (Land Use 932) is a related use. Additional Data Truck trips accounted for approximately 1 to 4 percent of the weekday traffic. The average for the sites surveyed was approximately 1.6 percent. Vehicle occupancy ranged from 1.59 to 1.98 persons per automobile on an average weekday. The average for the sites surveyed was approximately 1.78. The outdoor seating area is not included in the overall gross floor area. Therefore, the number of seats may be a more reliable independent variable on which to establish trip generation rates for facilities having significant outdoor seating. The sites were surveyed between the 1970s and the 1990s throughout the United States.

This type of restaurant is usually moderately priced and frequently belongs to a restaurant chain. Generally, these restaurants serve lunch and dinner; they may also be open for breakfast and are sometimes open 24 hours per day. These restaurants typically do not take -reservations. Patrons commonly wait to be seated, are served by a waiter/waitress, order from menus and pay for their meal after they eat. Some facilities contained within this land use may also contain a bar area for serving food and alcoholic drinks. Quality restaurant (Land Use 931), fast-food restaurant without drive-through window (Land Use 933), fast-food restaurant with drive-through window (Land Use 934) and fast-food restaurant with drive-through window and no indoor seating (Land Use 935) are related uses. Additional Data Users should exercise caution when applying statistics during the a.m. peak periods, as the sites contained in the database for this land use may or may not be open for breakfast_ In cases where it was confirmed that the sites were not open for breakfast, data for the a.m. peak hour of the adjacent street traffic were removed from the database. Vehicle occupancy ranged from 1.39 to 1.69 persons per automobile on an average weekday The average for the sites surveyed was approximately 1.52. Five sites submitted for inclusion in this land use indicated the presence of an on-site pick-up window. From the limited data sample, it does not appear that the presence of a pick-up window had a significant impact on trip generation. The outdoor seating area Is not included in the overall gross floor area. Therefore, the number of seats may be a more reliable independent variable on which to establish trip generation rates for facilities having significant outdoor seating. The sites were surveyed between the 1960s and the 2000s throughout the United States.
