Item 6D - Trip Generation Letter 12-1-19h MEMORANDUM WALKER C O N S U L T A N T S RPAI CENTRAL/MAIN RETAIL BUILDING -TRIP GENERATION ANALYSIS 27-1106.01 DATE: December 1, 2019 TO: Mr. Scott R. Miller COMPANY: Retail Properties of America, Inc. ADDRESS: 2021 Spring Road, Suite 300 CITY/STATE: Oak Brook, IL COPY TO: Mallory Baker FROM: Jeff Weckstein and James Warner, PE PROJECT NAME: Southlake Town Square RPAI Central Avenue and Main Street Retail Building—Trip Generation PROJECT NUMBER: 27-1106.01 Walker Consultants (Walker) is pleased to submit this trip generation analysis for the proposed retail building at Central Avenue and Main Street within Southlake Town. The proposed project consists of a 4,000 square foot retail outparcel building. The proposed project would displace 21 off-street parking spaces. Figure 1 shows the location of the proposed retail building Figure 1 Retail Building Site Image Source: Google Earth Pro, 2019 WALKER CONSULTANTS MEMORANDUM RPAI CENTRAL/MAIN RETAIL BUILDING -TRIP GENERATION ANALYSIS 27-1106.01 TRIP GENERATION ANALYSIS METHODOLOGY To determine the project's anticipated trip generation, Institute of Transportation Engineers (ITE) 10th Edition trip generation rates for the shopping center land use were utilized. The analysis calculates the AM peak hour trips, PM peak hour trips and average daily trips (ADT) forecast to be generated by the proposed retail outparcel building, which are the typical time periods analyzed in a traffic study. Additionally, since retail uses peak on Saturdays, the project's anticipated trip generation during the Saturday peak hour of the retail generator and Saturday daily trips have also been calculated. Table 1 summarizes the ITE trip generation rates for the proposed land use as well as the traffic generation of the proposed project based on these rates. Table 1: Trip Generation of Proposed RPAI Central Avenue and Main Street Retail Building Note: TSF = Thousand Square Feet As shown in Table 1, the proposed RPAI Central Avenue and Main Street Retail Building is projected to generate 4 weekday AM peak hour trips, 15 weekday PM peak hour trips and 151 weekday daily trips at the project driveways. The proposed project is projected to generate 18 Saturday peak hour trips and 184 Saturday daily trips at the project driveways. The analysis shown in Table 1 assumes no reduction in trip generation associated with internal trip capture even though the proposed retail building is part of a much larger super regional shopping center and office development. As shown in Figure 1, the block the proposed project site is on is served by four driveways, one on Grand Avenue, two on Main Street and one on Central Avenue serving the top level of the two-level parking deck on the block. These 4 driveways provide access to a 291 parking spaces for existing conditions (average of 73 per driveway) and will provide access to 270 parking spaces (68 per driveway) after construction of the proposed project, which will displace 21 parking spaces. Additionally, the block is served by 39 on -street parking spaces on Grand Avenue and Main Street. Overall, Southlake Town Square has 869,239 square feet of gross leasable area. The addition of 4,000 square feet of retail space represent a 0.46% increase in leasable space at the Town Square. 12
