INTRODUCTION This document provides information that demonstrates and justifies the traffic conditions that exempts the Clarksburg Premium Outlets at Cabin Branch from preparation of a Local Area Transportation Review (LATR) and Transportation Policy Area Review (TPAR). The Clarksburg Premium Outlets are part of, and integral to, the commercial development of the approved Cabin Branch Community. Cabin Branch is a comprehensively planned, mixed-use, transit-oriented, and pedestrian-friendly community on approximately 535-acres. The community is located west of the I- 270/Maryland 121 (Clarksburg Road) interchange in the Clarksburg policy area of Montgomery County, Maryland, as shown on Figure 1. The overall project includes 1,886 households and 2,420,000 square feet of commercial space. The Premium Outlets portion of the project changed 364,000 square feet of Medical and Research & Development uses to retail. With these changes, 484,000 total square feet of retail space would be provided with 450,000 square feet allocated to the Outlet Center and the remaining 34,000 square feet, allocated to neighborhood retail space. The retail space accounts for twenty percent (20%) of the total commercial space approved with the project. Table 1 illustrates the changes noted in comparison to the Phase II LATR completed November 2004.

TRIP GENERATION ANALYSIS The number of trips that will be generated by the approved Cabin Branch project were estimated based on standard MNCPPC and Institute of Transportation (ITE) trip generation rates. The development program included 1,886 total households, 500 elderly housing units, and 2,420,000 square feet of commercial space. The approved development program would generate approximately 3,671 total AM peak hour trips and 3,943 total PM peak hour trips, as shown on Table 2. To demonstrate that traffic conditions with the proposed Clarksburg Premium Outlets at Cabin Branch are within those trips generated previously, the proposed development program trips were estimated. The number of trips that will be generated by the proposed project were estimated using the same methodology as approved, except 364,000 square feet of commercial space (Medical and Research & Development uses) would be allocated to Outlet Center space for a total of 484,000 square feet of retail space. The Clarksburg Premium Outlets at Cabin Branch development program would generate 3,277 total AM peak hour trips and 3,465 total PM peak hour trips, as shown on Table 5. In comparison to the approved development program, the proposed development program would generate 394 fewer (-11%) AM peak hour trips and 499 fewer (-13%) PM peak hour trips as shown on the bottom of Table 3. Based on this trip generation analysis completed, the proposed project would fall within the trip allocation previously analyzed in the November 2004 LATR for Cabin Branch. This analysis confirms the Traffic Exemption requirement of less than 30 new weekday peak hour trips for LATR and less than three (3) trips for TPAR as noted in the January 2013 LATR and TPAR Guidelines. In addition, since the trip generation analysis indicates the proposed project trips are fewer than the trips used to analyze local intersections, the development program change would also not change the expected operation and improvements conditioned with the Cabin Branch approval. 4

CONCLUSIONS The conclusions of this traffic exemption statement are as follows: 1. The overall development density of the Cabin Branch Community would remain as approved with 1,886 households and 2,420,000 square feet of commercial space. The Premium Outlets portion of the project changes 364,000 square feet of Medical and Research & Development uses to retail allowing 450,000 square feet for the Outlet Center. 2. The Clarksburg Premium Outlets at Cabin Branch is estimated to generate 3,277 total AM peak hour trips and 3,465 total PM peak hour trips at project build-out. In comparison to the approved development program, the planned development program would generate 394 fewer (-11%) AM peak hour trips and 499 fewer (-13%) PM peak hour trips. 3. The Clarksburg Premium Outlets at Cabin Branch trips would fall within the trip allocation previously analyzed and indicates the project trips will be adequately accommodated by the improvements planned with the approved project. 7
