MEMORANDUM
To:Alex Morganroth, AICP, Senior Planner, City of Renton

Subject: Chipotle – Renton Washington (KH 090191000)
Trip Generation and Transportation Impact Fees
Kimley-Horn and Associates, Inc. (Kimley-Horn) has been retained to provide a trip generation
memorandum for a proposed Chipotle Development (Development) in the City of Renton (City). This
memo summarizes the trip generation and transportation impact fees for the change of use for the
existing building. The Development is located along the west side of Benson Road S, north of SE 180 th
Street, on parcel 3223059065. The site is currently listed as occupied with a drive-in bank per the King
County Parcel Viewer webpage but appears to currently have a mix of commercial uses based on
online mapping information. A site vicinity map is shown in Figure 1.

1. TRIP GENERATION
The Development is proposed to consist of a 3,182 square foot (SF) fast casual restaurant. The trip
generation calculations have been performed using data published by the Institute of Transportation
Engineers (ITE)Trip Generation Manual, 11st Edition (2021) as outlined in the City of Renton
Transportation Impact Analysis (TIA) Guidelines.The average trip generation rates for ITE Land Use
Code (LUC) 930, Fast Casual Restaurant, have been used for the trip generation for the proposed
Development. ITE does not identify a pass-by rate for a Fast Casual Restaurant; therefore, no pass-by
rate was applied to be conservative. However, it would be anticipated that a pass-by rate similar to high
turnover sit down restaurant could be applied. The trip generation for the Fast Casual Restaurant is
summarized in Table 1.
The existing 3,182 SF building on-site is a Drive-in Bank and credit for the existing use is based on
average trip generation rates for ITE LUC 912, Drive-In Bank. It is important to note that ITE LUC 912
has an AM peak-hour pass-by rate of 29% and a PM peak-hour pass-by rate of 35% based on GFA.
To remain conservative in the total anticipated volumes, the higher pass-by rate of 35% has been
applied to the ADT generation. The trip generation calculations for the Drive-in Bank are summarized
in Table 2.

The Development is anticipated to generate approximately 102 new ADTs with 17 fewer AM peak-hour
trips and 3 fewer PM peak-hour trips after pass-by reductions and credit for the existing on-site use has
been applied. The trip generation shows the Development will not generate more than 20 peak-hour
vehicle trips to the adjacent roadway system; therefore, no trip distribution is required. The City would
therefore not require a full traffic impact analysis (TIA). The trip generation calculations are provided in
Appendix A.

2. TRANSPORTATION IMPACT FEES
The City imposes transportation impact fees on new developments based on the rates of the City of
Renton Fee Schedule 2023-2024 revised April 2024.The schedule provides a fee per square foot of
$68.10 for the Fast Casual Restaurant. According to RMC 4-1-190G, when an impact fee applies to a
change in land use, the applicable impact fee for the land use category will receive credit for the
previously paid land use category. The fee per square foot for the drive-in bank is $120.84 that will be
credited towards the Developments transportation impact fee. Based on the square footage of the
building not increasing with the Development and a transportation impact fee credit for the bank of
$52.74 per square foot; a transportation impact fee would therefore not be required for the
Development. The City of Renton Fee Schedule 2023-2024 revised April 2024 is provided in Appendix
B.
