TECHNICAL MEMORANDUM To: From: John M. Welsh Chris Furlong AHC, Inc. Andrew T. Smith, P.E. Edward Y. Papazian, P.E. Kimley-Horn and Associates, Inc. Date: July 6, 2017 Subject: 200 9 th reet South Redevelopment Existing Transportation Conditions Introduction This memorandum summarizes the existing transportation conditions for the 200 9 th reet South Redevelopment project located in Arlington County, Virginia. The project site is located north of and is bordered by 9 th reet S. on the north, a public alley on the south, S. Adams reet on the west, and S. Wayne reet on the east. The site location is shown on Figure 1. The site currently contains a 7-story, 6,5 square-foot office building with a two-level, aboveground parking garage. The existing building will remain but will be adaptively reused and converted into up to 80 affordable apartment units. Portions of the parking garage will be removed and replaced with up to 10 market-rate townhomes. An amendment to the General Land Use Plan (GLUP) for the adaptive reuse of the property is required as a part of the site redevelopment. The property is currently designated as the Service Commercial land use. The project proposes to amend the current GLUP to modify portions of the site that will be converted to townhomes to the Residential Low-Medium land use, which allows for 16-6 units per acre. This memorandum summarizes the existing transportation information that is required as a part of the GLUP amendment. A full traffic impact study that evaluates the impact of the proposed residential redevelopment has not yet been prepared, but will be submitted as required as a part of the.1 Site Plan application. Area Transportation System The following sections describe the existing and future street network, area transit service, and pedestrian and bicycle facilities in the site vicinity. kimley-horn.com 1100 Commerce Park Drive, Suite 00, Reston, VA 20191 70 67 100

PEDESTRIAN AND BICYCLE FACILITIES The project site is located within an extensive pedestrian and bicycle network. The pedestrian and bicycle facilities are described in the following sections, and shown on Figure. Pedestrian Facilities All streets in the site vicinity contain sidewalks on both sides of the street. Signalized intersections contain crosswalks across each intersection leg. Bicycle Facilities S. Wayne reet and 9 th reet S. are designated on-street bicycle routes by Arlington County. The intersections of 9 th reet S. with S. Adams reet and with S. Wayne reet contain shared lane markings ( sharrows ). These bicycle routes connect with designated bike lanes on Walter Reed Drive to the west and 6 th reet to the north. Future Bicycle Facilities The Bike Boulevards project is a bicycle and pedestrian improvement project that will improve the bicycle routes along 9 th reet S. and 12 th reet S. between S. George Mason Drive and S. Wayne reet. Scheduled to begin construction in summer 2017, the project includes updates to facilities along 9 th reet S. in the vicinity of the site. This project consists of improvements to both the 9 th reet and S. Adams reet intersection and the 9 th reet S. and S. Wayne reet intersection including curb extensions, driveway aprons, and ADA compliant curb ramps.

Walter Reed Drive. kimley-horn.com 1100 Commerce Park Drive, Suite 00, Reston, VA 20191 70 67 100
Page Capital Bikeshare There are three Capital Bikeshare stations located within 1,000 feet of the site. The stations are located at the intersections of and Courthouse Road, and S. Edgewood reet, and S. Walter Reed Drive and 8 th reet S. Existing Traffic Volumes Existing peak period vehicular, pedestrian, and bicycle counts were conducted at the following study area intersections on Tuesday, June 6, 2017 between 6:0 AM and 9:0 AM and between :00 PM and 7:00 PM: and S. Adams reet and S. Wayne reet 9 th reet S. and S. Adams reet 9 th reet S. and S. Wayne reet These counts were used to establish current peak hour traffic volumes. A common peak hour for all the study intersections was established by identifying the peak 60 minutes of traffic for all intersections combined during the AM and PM peak periods. Based on these traffic counts, the overall traffic peak hours were identified as 8:00-9:00 AM during the AM peak period and 5:00-6:00 PM during the PM peak period. The existing peak hour traffic volumes at the study intersections are shown on Figure 5. Existing peak hour pedestrian and bicycle counts for the same common peak hours are shown on Figures 6 and 7, respectively. The appendix of this memorandum contains the traffic count summaries. Proposed Development and Site Access The proposed 200 9 th reet South development consists of the adaptive reuse of an existing office building and above-grade parking garage. The existing building contains 6,5 gross square feet of office area that will be converted into 80 multifamily affordable apartments. The portions of the parking deck located adjacent to S. Adams reet and S. Wayne reet will be demolished and replaced with up to 10 market-rate townhomes. Access to the second level of the parking deck that remains on the proposed site will still be provided via an existing ramp on 9 th reet S. Access to the lower level of parking will be provided at an existing entrance on 9 th reet S. and a proposed entrance on the alley located south of the site that connects S. Wayne reet and S. Adams reet. The existing exit on S. Adams reet will be removed. The existing and proposed site access is shown on Figure 8. Site Trip Generation Site generated traffic volumes were calculated for the proposed 200 9 th reet South Redevelopment based on the peak-hour vehicle-trip generation rates for mid-rise apartments (Land Use Code 22) and residential condominium/townhouse (Land Use Code 20) contained in the ITE Trip Generation Manual, 9th Edition. Existing office peak-hour trips were calculated based on the vehicle-trip generation rates for general office building (Land Use Code 710), also contained in the kimley-horn.com 1100 Commerce Park Drive, Suite 00, Reston, VA 20191 70 67 100
Page 5 ITE Trip Generation Manual. The trip figures do not consider adjustments resulting from the proximity of transit in the study area.

Summary The proposed 200 9 th reet South Redevelopment project will provide affordable apartments and market-rate townhomes as a part of an adaptive reuse of an existing office building. The site is well served by public transit along the corridor. The site is also located along designated bicycle routes, and the surrounding streets contain adequate pedestrian facilities. Once redeveloped, the site will generate far fewer trips in the AM and PM peak hours than the existing use kimley-horn.com 1100 Commerce Park Drive, Suite 00, Reston, VA 20191 70 67 100
