INTRODUCTION This report presents the results of a Local Area Transportation Review (LATR) and Transportation Policy Area Review (TPAR) for Comstock Newell, LC (the “Applicant”) planned development, 8001 Newell Street, within the Silver Spring Central Business District (CBD) Policy Area. 8001 Newell Street (the “Property”) is located southeast of Newell Street and northeast of Eastern Avenue within the Silver Spring CBD Policy Area of Montgomery County, Maryland, as shown on Figure 1-1. The site presently is developed with self-storage units with a total of approximately 40,000 S.F. of warehouse space. Comstock Newell, LC proposes to redevelop the site with a mix of retail and residential uses (the “Project”). For purposes of this LATR and TPAR study, the following development program was assumed. It is understood that the size of the uses may vary. To provide flexibility, the development program analyzed was assumed to generate a maximum number of site vehicle trips and therefore provides a conservative analysis. Land Use Size High Rise: 187 D.U. Retail: 3,100 S.F. This LATR and TPAR study was conducted in accordance with the Maryland-National Capital Park and Planning Commission’s (M-NCPPC) LATR and TPAR Guidelines. The scope of this LATR and TPAR study was established in consultation with M-NCPPC staff. A copy of the M- NCPPC letter describing the study’s scope is included as Appendix A. Tasks undertaken in this study included the following: 1. Review Comstock Newell, LC’s proposed development plans, previous traffic studies conducted in the area, and other background data. 2. A field reconnaissance of existing roadway and intersection geometrics, traffic controls, traffic signal phasings/timings, and speed limits. 3. Conduct existing vehicular and pedestrian counts at six (6) off-site intersections. 4. Analysis of existing critical lane volumes (CLVs) at each of the six (6) off-site intersections. 5. Future traffic volumes without the Project were forecasted based on existing traffic counts and traffic generated by six (6) other pipeline developments within the study area. 1 8001 Newell Street Local Area Transportation Review and Transportation Policy Area Review Montgomery County, Maryland 6. Future CLVs without the Project were calculated at each of the six (6) off-site intersections. The existing traffic controls and existing intersection geometrics, including recommended improvements, were part of these future CLV calculations. 7. The number of weekday AM and PM peak hour trips that will be generated by the Project were estimated based on LATR and TPAR Guidelines rates. 8. The directional distributions of the site generated trips were determined based on M- NCPPC procedures. 9. Total future traffic forecasts were calculated based on background (pipeline) traffic forecasts plus all site-generated trips assigned to the area roadway network. 10. Total future CLVs with the Project were calculated at each of the six (6) off-site intersections. 11. A pedestrian and bicyclist statement was prepared in accordance with the LATR and TPAR Guidelines. 12. Transportation Policy
