Future Conditions With Development (2017):
In order to determine future traffic volumes on the roadways in the vicinity of the site under the 2017 build condition, the site-generated traffic volumes were added to the 2017 future background traffic volumes.
The proposed development will generate a total of 188, 333 and 287 net new trips in the morning, afternoon and Saturday peak hours, respectively.
The parking garage will be accessed by one full-access driveway along S. Elm Street.
All intersections continue to operate at acceptable LOS under a future scenario with the proposed development.
Transportation Management Plan: A TMP will be required for the project based on the County’s requirements. The framework for a TMP is included in this report.

INTRODUCTION AND SUMMARY Purpose of Report and Study Objectives This report presents the findings of a traffic impact study conducted for the proposed development of Metropolitan Park th
4/5 located at 1200 S Eads Street in the southwest corner of 12 Street S and S Eads Street in Arlington, VA. The study area th
is bounded by S Eads Street to the east, the future S Elm Street to the west, future 12 Street S to the north and the future th
13 Street S to the south. The proposed plan is a mixed use development consisting of 699 residential units and a grocery store with approximately 40,000 square feet of space. The proposed project build-out year is 2017. The primary objective of this study is to identify the impacts to the transportation network due to the proposed development. The study area encompasses eight intersections near the site. Elements of this report include the existing transportation network, the transportation elements of the proposed development, and the possible impacts to the transportation network. The following tasks were completed as part of this study.
A scoping meeting was conducted on May 15, 2012, and a scope dated May 17, 2012 was agreed upon by Gorove/Slade and representatives from the Arlington County.
This scope included discussions about the
parameters of the study and relevant background information. A copy of the scoping document confirming the parameters and assumptions used is included in the Technical Appendix.
Field reconnaissance in the vicinity of the site was performed to collect information related to the existing traffic controls, roadway geometry, and traffic flow characteristics.
Traffic counts at unsignalized and signalized intersections were conducted on Wednesday, March 21, 2012, Wednesday, May 16, 2012 and Saturday, May 19, 2012, during the morning, afternoon and Saturday peak hours.
Future traffic conditions were projected based on inherent traffic growth of one percent (1%) compounded annually to account for regional growth along the roadway network. As outlined in the scoping document, one background development was considered for this study.
Proposed site traffic volumes were generated based on the methodology outlined in the Institute of Transportation Engineers’ (ITE) Trip Generation, 8th Edition.
Intersection capacity analyses were performed using the software package Synchro, Version 7.0 based on the Highway Capacity Manual (HCM) methodology. Traffic analyses were performed for the existing conditions (2012) and future conditions with and without development (2017).
A Transportation Management Plan framework was developed as a TMP will be necessary according to County requirements.
Sources of data for this study include Arlington County, the Virginia Department of Transportation (VDOT), the Institute of Transportation Engineers (ITE) Trip Generation, 8th Edition, Vornado/Charles E. Smith, VIKA, Inc. and the office files and field reconnaissance efforts of Gorove/Slade Associates, Inc.

General Land Use Plan Recommendations for the Subject Property According to Arlington County’s General Land Use Plan (GLUP), this site is currently listed as a mix of high-medium residential land use and medium office-apartment-hotel uses. The GLUP map for the site is shown in Figure 3. Due to the sites proximity to two Metro stations (Pentagon City Station and Crystal City Station), Arlington County classifies the site area as a Metro Station Area (MSA). “Boundaries for these “Metro Station Areas” (MSAs) have been drawn based on this quarter mile radius (a suitable walking distance to and from the Metro and residential, retail or office buildings) and a combination of major transportation routes, Census geography and neighborhood boundaries. The seven MSAs have been carefully planned for mixed used development (generally retail, office, educational or institutional, and residential) to create vibrant nodes of activity within the County. Each station area has been planned for a unique mix of development to highlight various goals of the County. Crystal City and Rosslyn are predominantly high density office, hotel, and residential station areas while Clarendon has been identified as an “urban village,” and is an emerging retail center for the County. Virginia Square includes a diverse mix of educational (it is home to a campus of George Mason University), office and residential uses. Ballston and Pentagon City are the major retail centers for the County surrounded by office, hotel, and residential uses. Court House is the home of the County government and courts as well as several high rise office and residential buildings.” - Arlington County website July 13, 2012

Existing Capacity Analysis Capacity analyses were performed at the intersections within the study area during the weekday morning, afternoon and Saturday peak hours under the existing conditions. Synchro, Version 7.0 was used to analyze the study intersections based on the Highway Capacity Manual (HCM) methodology and include level of service, delay, and queue length comparisons for the turning movements analyzed. For all intersections, the field peak hour factor by approach was used. The results of the intersection capacity analyses are presented in Table 1, and are expressed in level of service (LOS) and delay (seconds per vehicle) per lane group. The 95% and 50% queue results for each intersection are also presented in Table 1, and are expressed in feet. The results of the intersection capacity analyses are illustrated Figure 11.
The detailed analysis worksheets and a
description of the different LOS and delay are included in the Technical Appendix. Table 1: Existing (2012) Capacity Analysis Results

Notes:
N/A – Not Applicable # – 95th percentile volume exceeds capacity, queue may be longer. Queue shown is the maximum after two cycles. ~ - indicates that the approach is above capacity and the queue length could be much longer. The queue length is theoretically infinite and blocking problems may occur. m – Volume for 95th percentile queue is metered by upstream signal * – Delay/queue is too long to calculate.
For the purpose of this analysis, it is desirable to achieve a level of service (LOS) of “D” or better for each approach to an intersection. The results in the table above show that all intersections have movements that operate at acceptable LOS under existing conditions.

FUTURE CONDITIONS WITHOUT DEVELOPMENT (2017) Future without Development Traffic Volumes The proposed mixed use development is anticipated to be completed in 2017. The future traffic volumes were projected by increasing the existing traffic volumes to the build-out year using an inherent growth rate based on historical traffic growth provided by VDOT as well as previous studies in the area. According to historical data provided by VDOT, there has been little or no growth along streets within the study areas in recent years. However, to be conservative and consistent with other studies performed in the area, a 1.0% growth per year over a five year period (5.1%) was applied to the existing volumes to account for regional increase in background traffic. In addition to the regional inherent growth, one approved background development in the vicinity of the site was taken into consideration. As discussed at the scoping meeting, Metropolitan Park III was the only background development that th
th
was included in the analysis. Metropolitan Park III is bounded by future 12 Street S, future 13 Street S, S. Fern Street and future Elm Street. Table 2 summarizes the trips generated by the approved background development.
Planned Background Improvements As previously noted, 12th Street will be extended between S. Fern Street and S. Eads Street. It will be one-way in the th
eastbound direction. S. Elm Street to the west of the proposed site will also be extended to 13 Street. The location and the trips generated by the approved background development and improvements are illustrated in Figure 12 and Figure 13. Table 2: Background Approved Trip Generation Land Use

Future without Development Capacity Analysis Capacity analyses were performed at the intersections contained within the study area during the weekday morning, afternoon and Saturday peak hours under the future without development conditions. Synchro, Version 7.0 was used to analyze the study intersections based on the Highway Capacity Manual (HCM) methodology and include level of service, delay, and queue length comparisons for the turning movements analyzed. A peak hour factor of 0.92 was used in the analysis of the future traffic conditions instead of the existing peak hour factors, since the current traffic patterns were anticipated to change as part of the future development within the study area. th
th
It should be noted that signal operation at the intersections of 12 Street S. and S. Eads Street, and 12 Street S. and S. Fern Street was modified from the Synchro files provided by the County to account for the new leg at each of these th
intersections. Permitted left turns were assumed for eastbound and westbound left turns at 12 Street S. and S. Eads Street th
and southbound left turns at 12 Street S. and S. Fern Street. The results of the intersection capacity analyses are presented in Table 3, and are expressed in level of service (LOS) and delay (seconds per vehicle) per lane group. The 95% and 50% queue results for each intersection are also presented in Table 3, and are expressed in feet. The detailed analysis worksheets and a description of the different LOS and delay are contained in the Technical Appendix. The results of the intersection capacity analyses are shown on Figure 15. The detailed analysis worksheets and a description of the different LOS and delay are contained in the Technical Appendix. Table 3: Future without Development (2017) Capacity Analysis Results

Traffic Impact Study and Transportation Management Plan – Metropolitan Park 4/5
FUTURE CONDITIONS WITH DEVELOPMENT (2017) th
The subject site is located in the Pentagon City area of Arlington, Virginia, at the southwest corner of 12 Street S. and S. th
Eads Street. The study area is bounded by S, Eads Street to the east, the future S. Elm Street to the west, future 12 Street th
S. to the north and the future 13 Street S. to the south. Regional access to the site is provided via I-395 and VA-110 from the north and east, Route 1 (Jefferson Davis Highway) and I-395 to the south and VA-27 and VA-244 to the west. Immediate th
th
th
access to the site will be provided via S. Eads Street, S. Fern Street, 12 Street S., 13 Street S., 15 Street S. and direct access to the parking garage is provided via S. Elm Street. Figure 16 shows the proposed lane configuration and traffic controls for future build-out.
Site Access Access to the parking garage for residential and grocery is provided via a driveway located along S. Elm Street. There are th
three curb cuts located on 13 Street S. and S. Elm Street for loading access and one curb cut on S. Elm Street for the parking garage. The proposed site plan for the redevelopment is shown in Figure 17.
Site Generated Volumes The Institute of Transportation Engineers (ITE) Trip Generation, 8
th
Edition, was used to determine the future trips
generated by the proposed development. A pass-by reduction of 25% was assumed for retail use to account for drivers already on the road that come to the retail stores and then continue in the direction they were originally heading.
Residential Trip Reduction: The site is located on a Metrobus/ART bus corridor on S Eads Street, and there are two Metro stations within a half mile of the site. It is expected that a portion of the residents will arrive by Metrorail, bus, cab or on foot/by bicycle, rather than by personal vehicle. Based on data from Table S-2 of the 2005 WMATA Ridership Survey, residential sites within ¼ mile of a Metro Station have a non-auto mode share of 59%. Table S-3 of the WMATA Survey shows that residential sites within the Beltway have a non-auto mode share of 61%. Therefore, as shown in Table 4, a 60% reduction rate will be applied to the peak hours to reflect the non-auto transit, biking, and walking modes.
Retail Trip Reduction: As noted above, the site is located near many transit options and near many different uses, including residential, office and other retail. Therefore, it is expected that many employees/customers will arrive via modes other than single occupant vehicles. Based on data provided in the 2005 WMATA survey for other retail sites in Crystal City and Ballston, an average non-auto mode share of approximately 69% was observed. In order to provide a conservative analysis, a 50% reduction rate will be applied to the peak hours to reflect the non-auto transit, biking, and walking modes. Table 4 illustrates these reductions.

The above table shows that the proposed development will generate approximately 188 new trips in the weekday morning peak hour, approximately 333 new trips in the weekday afternoon peak hour and approximately 287 new trips in the Saturday peak hour.
Site Trip Distribution The distribution of site trips was based primarily on existing volumes, anticipated traffic patterns and other recent studies conducted in the area. The peak hour trips were calculated and assigned to the roadway network based on the traffic distribution, which is shown graphically in Figure 18. The site generated trips and pass-by trips are shown in Figure 19 and Figure 20.

Traffic Impact Study and Transportation Management Plan – Metropolitan Park 4/5
Future with Development Traffic Volumes In order to determine the traffic volumes on the roadways in the vicinity of the development under the 2017 build condition, the site generated traffic volumes were added to the 2017 future background traffic volumes. The traffic volumes for the total future scenario are shown on Figure 21.
Future with Development Capacity Analysis Capacity analyses were performed at the intersections contained within the study area during the weekday morning, afternoon and Saturday peak hours, under the future with development conditions. Synchro, Version 7.0 was used to analyze the study intersections based on the Highway Capacity Manual (HCM) methodology and include level of service, delay, and queue length comparisons for the turning movements analyzed. As previously mentioned, a peak hour factor of 0.92 was used in the analysis of the future traffic conditions. th
th
It should be noted that signal operation at the intersections of 12 Street S. and S. Eads Street, and 12 Street S. and S. Fern Street was modified from the Synchro files provided by the County to account for the new leg at each of these th
intersections. Permitted left turns were assumed for eastbound and westbound left turns at 12 Street S. and S. Eads Street th
and southbound left turns at 12 Street S. and S. Fern Street. The results of the intersection capacity analyses are presented in Table 6 and are expressed in level of service (LOS) and delay (seconds per vehicle) per lane group. The 95% and 50% queue results for each intersection are also presented in Table 6, and are expressed in feet.

TRANSPORTATION MANAGEMENT PLAN A Transportation Management Plan (TMP) has many components that are tailored to accommodate a given facility with the goal being the reduction of automobile trips by encouraging alternative forms of transportation. A few of the typical TMP components include the establishment of a TMP coordinator, the distribution of transit literature, the establishment of ride-sharing programs, the sale of on-site discounted fare media, and the designation of carpool and/or vanpool spaces. Management measures taken by Metropolitan Park 4/5 can be monitored and adjusted as needed to continually create opportunities to reduce the amount of traffic generated by the site. The Transportation Management Plan shall include a schedule and details of implementation and continued operation of the elements in the plan. The location of the site near the Pentagon City Metro Station allows for a TMP that can include, but not be limited to, the following: Participation and Funding a.
The Applicant will maintain an active membership in Arlington Transportation Partners (ATP), or successor entity at no cost to the developer, on behalf of the property management company.
b.
The Applicant will designate a member(s) of the building management team as Property Transportation Coordinator who will be the primary point of contact and will be responsible for coordinating and completing TDM obligations on behalf of the Applicant. The applicant will provide the name of the Property Transportation Coordinator to the Commuter Assistance Program.
c.
Provide contributions as negotiated with Arlington County staff during the 4.1 Site Plan process.
Facilities and Improvements a.
Provide in the new building one information display with transportation related information for residents, employees and visitors, the content/design/location of which shall be mutually agreeable to ACCS and Applicant.
b.
Maintain one on-site business center in the building (including access to a copier, fax, pc, and internet services), which shall be made available to support building residents.
c.
Comply with requirements of the Site Plan conditions to provide bicycle parking/storage facilities and construction worker parking.
Parking Management Plan a.
Prepare a Parking Management Plan to show how adjacent curb space to the site will be designated for parking and a potential on-street loading zones.
Promotions, Services, Policies a.
Provide Smart Trip cards to residents and/or employees as negotiated with Arlington County staff during the 4.1 Site Plan process.
b.
Provide website hotlinks to CommuterPage.com manager’s websites regarding this development.

Traffic Impact Study and Transportation Management Plan – Metropolitan Park 4/5
CONCLUSIONS The transportation network surrounding the subject site provides excellent regional and local access, and numerous pedestrian and transit options. The site is located in the Pentagon City area of Arlington, Virginia, at the southwest corner th
of 12 Street S. and S. Eads Street. The study area is bounded by S. Eads Street to the east, the future S. Elm Street to the th
th
west, future 12 Street S. to the north and the future 13 Street S. to the south. Regional access to the site is provided via I395 and VA-110 from the north and east, Route 1 (Jefferson Davis Highway) and I-395 to the south and VA-27 and VA-244 th
th
to the west. Immediate access to the site will be provided via S. Eads Street, S. Fern Street, 12 Street S., 13 Street S., 15
th
Street S. and direct access to the parking garage is provided via S. Elm Street. The analysis presented in this report supports the following major conclusions:
Existing Conditions (2012):
The Pentagon City Metro Station is located at the southeast corner of South Hayes Street and 12
th
Street
intersection, less than a quarter (1/4) mile walking distance from the site. The Pentagon City Metro serves both the Blue and Yellow lines.
The subject site is located near several Metrobus and ART bus lines that have stops in the vicinity of the site.
At least nine (9) Metrobus lines; 10A, 16G, 16H, 16W, 9A, 9E, 13B, 13F, and 13G travel through the study area with bus stops located within one block of the site.
Under existing conditions, all intersections operate at acceptable LOS.
Future Conditions Without Development (2017):
With an inherent growth rate of 1% at the study intersections and assumed background development and improvements, all intersections have movements that continue to operate at acceptable LOS under future without development conditions.
Future Conditions With Development (2017):
In order to determine future traffic volumes on the roadways in the vicinity of the subject site under the 2017 build condition, the site-generated traffic volumes were added to the 2017 future background traffic volumes.
The proposed development will generate a total of 188, 333 and 287 net new trips in the morning, afternoon and Saturday peak hours, respectively.
Parking to the site will be accessed by one driveway along Elm Street.
All intersections within the study area operate at acceptable LOS with the proposed Metropolitan Park 4/5 development.
Transportation Management Plan
A TMP will be required for the project based on the County’s requirements. The framework for a TMP is included in this report.

INTRODUCTION AND SUMMARY Purpose of Report and Study Objectives This report presents the findings of a traffic impact study conducted for the proposed development of Metropolitan Park th
4/5 located at 1200 S Eads Street in the southwest corner of 12 Street S and S Eads Street in Arlington, VA. The study area th
is bounded by S Eads Street to the east, the future S Elm Street to the west, future 12 Street S to the north and the future th
13 Street S to the south. The proposed plan is a mixed use development consisting of 699 residential units and a grocery store with approximately 40,000 square feet of space. The proposed project build-out year is 2017. The primary objective of this study is to identify the impacts to the transportation network due to the proposed development. The study area encompasses eight intersections near the site. Elements of this report include the existing transportation network, the transportation elements of the proposed development, and the possible impacts to the transportation network. The following tasks were completed as part of this study.
A scoping meeting was conducted on May 15, 2012, and a scope dated May 17, 2012 was agreed upon by Gorove/Slade and representatives from the Arlington County.
This scope included discussions about the
parameters of the study and relevant background information. A copy of the scoping document confirming the parameters and assumptions used is included in the Technical Appendix.
Field reconnaissance in the vicinity of the site was performed to collect information related to the existing traffic controls, roadway geometry, and traffic flow characteristics.
Traffic counts at unsignalized and signalized intersections were conducted on Wednesday, March 21, 2012, Wednesday, May 16, 2012 and Saturday, May 19, 2012, during the morning, afternoon and Saturday peak hours.
Future traffic conditions were projected based on inherent traffic growth of one percent (1%) compounded annually to account for regional growth along the roadway network. As outlined in the scoping document, one background development was considered for this study.
Proposed site traffic volumes were generated based on the methodology outlined in the Institute of Transportation Engineers’ (ITE) Trip Generation, 8th Edition.
Intersection capacity analyses were performed using the software package Synchro, Version 7.0 based on the Highway Capacity Manual (HCM) methodology. Traffic analyses were performed for the existing conditions (2012) and future conditions with and without development (2017).
A Transportation Management Plan framework was developed as a TMP will be necessary according to County requirements.
Sources of data for this study include Arlington County, the Virginia Department of Transportation (VDOT), the Institute of Transportation Engineers (ITE) Trip Generation, 8th Edition, Vornado/Charles E. Smith, VIKA, Inc. and the office files and field reconnaissance efforts of Gorove/Slade Associates, Inc.

General Land Use Plan Recommendations for the Subject Property According to Arlington County’s General Land Use Plan (GLUP), this site is currently listed as a mix of high-medium residential land use and medium office-apartment-hotel uses. The GLUP map for the site is shown in Figure 3. Due to the sites proximity to two Metro stations (Pentagon City Station and Crystal City Station), Arlington County classifies the site area as a Metro Station Area (MSA). “Boundaries for these “Metro Station Areas” (MSAs) have been drawn based on this quarter mile radius (a suitable walking distance to and from the Metro and residential, retail or office buildings) and a combination of major transportation routes, Census geography and neighborhood boundaries. The seven MSAs have been carefully planned for mixed used development (generally retail, office, educational or institutional, and residential) to create vibrant nodes of activity within the County. Each station area has been planned for a unique mix of development to highlight various goals of the County. Crystal City and Rosslyn are predominantly high density office, hotel, and residential station areas while Clarendon has been identified as an “urban village,” and is an emerging retail center for the County. Virginia Square includes a diverse mix of educational (it is home to a campus of George Mason University), office and residential uses. Ballston and Pentagon City are the major retail centers for the County surrounded by office, hotel, and residential uses. Court House is the home of the County government and courts as well as several high rise office and residential buildings.” - Arlington County website July 13, 2012

Existing Capacity Analysis Capacity analyses were performed at the intersections within the study area during the weekday morning, afternoon and Saturday peak hours under the existing conditions. Synchro, Version 7.0 was used to analyze the study intersections based on the Highway Capacity Manual (HCM) methodology and include level of service, delay, and queue length comparisons for the turning movements analyzed. For all intersections, the field peak hour factor by approach was used. The results of the intersection capacity analyses are presented in Table 1, and are expressed in level of service (LOS) and delay (seconds per vehicle) per lane group. The 95% and 50% queue results for each intersection are also presented in Table 1, and are expressed in feet. The results of the intersection capacity analyses are illustrated Figure 11.
The detailed analysis worksheets and a
description of the different LOS and delay are included in the Technical Appendix. Table 1: Existing (2012) Capacity Analysis Results

Notes:
N/A – Not Applicable # – 95th percentile volume exceeds capacity, queue may be longer. Queue shown is the maximum after two cycles. ~ - indicates that the approach is above capacity and the queue length could be much longer. The queue length is theoretically infinite and blocking problems may occur. m – Volume for 95th percentile queue is metered by upstream signal * – Delay/queue is too long to calculate.
For the purpose of this analysis, it is desirable to achieve a level of service (LOS) of “D” or better for each approach to an intersection. The results in the table above show that all intersections have movements that operate at acceptable LOS under existing conditions.

FUTURE CONDITIONS WITHOUT DEVELOPMENT (2017) Future without Development Traffic Volumes The proposed mixed use development is anticipated to be completed in 2017. The future traffic volumes were projected by increasing the existing traffic volumes to the build-out year using an inherent growth rate based on historical traffic growth provided by VDOT as well as previous studies in the area. According to historical data provided by VDOT, there has been little or no growth along streets within the study areas in recent years. However, to be conservative and consistent with other studies performed in the area, a 1.0% growth per year over a five year period (5.1%) was applied to the existing volumes to account for regional increase in background traffic. In addition to the regional inherent growth, one approved background development in the vicinity of the site was taken into consideration. As discussed at the scoping meeting, Metropolitan Park III was the only background development that th
th
was included in the analysis. Metropolitan Park III is bounded by future 12 Street S, future 13 Street S, S. Fern Street and future Elm Street. Table 2 summarizes the trips generated by the approved background development.
Planned Background Improvements As previously noted, 12th Street will be extended between S. Fern Street and S. Eads Street. It will be one-way in the th
eastbound direction. S. Elm Street to the west of the proposed site will also be extended to 13 Street. The location and the trips generated by the approved background development and improvements are illustrated in Figure 12 and Figure 13. Table 2: Background Approved Trip Generation Land Use

Future without Development Capacity Analysis Capacity analyses were performed at the intersections contained within the study area during the weekday morning, afternoon and Saturday peak hours under the future without development conditions. Synchro, Version 7.0 was used to analyze the study intersections based on the Highway Capacity Manual (HCM) methodology and include level of service, delay, and queue length comparisons for the turning movements analyzed. A peak hour factor of 0.92 was used in the analysis of the future traffic conditions instead of the existing peak hour factors, since the current traffic patterns were anticipated to change as part of the future development within the study area. th
th
It should be noted that signal operation at the intersections of 12 Street S. and S. Eads Street, and 12 Street S. and S. Fern Street was modified from the Synchro files provided by the County to account for the new leg at each of these th
intersections. Permitted left turns were assumed for eastbound and westbound left turns at 12 Street S. and S. Eads Street th
and southbound left turns at 12 Street S. and S. Fern Street. The results of the intersection capacity analyses are presented in Table 3, and are expressed in level of service (LOS) and delay (seconds per vehicle) per lane group. The 95% and 50% queue results for each intersection are also presented in Table 3, and are expressed in feet. The detailed analysis worksheets and a description of the different LOS and delay are contained in the Technical Appendix. The results of the intersection capacity analyses are shown on Figure 15. The detailed analysis worksheets and a description of the different LOS and delay are contained in the Technical Appendix. Table 3: Future without Development (2017) Capacity Analysis Results

Traffic Impact Study and Transportation Management Plan – Metropolitan Park 4/5
FUTURE CONDITIONS WITH DEVELOPMENT (2017) th
The subject site is located in the Pentagon City area of Arlington, Virginia, at the southwest corner of 12 Street S. and S. th
Eads Street. The study area is bounded by S, Eads Street to the east, the future S. Elm Street to the west, future 12 Street th
S. to the north and the future 13 Street S. to the south. Regional access to the site is provided via I-395 and VA-110 from the north and east, Route 1 (Jefferson Davis Highway) and I-395 to the south and VA-27 and VA-244 to the west. Immediate th
th
th
access to the site will be provided via S. Eads Street, S. Fern Street, 12 Street S., 13 Street S., 15 Street S. and direct access to the parking garage is provided via S. Elm Street. Figure 16 shows the proposed lane configuration and traffic controls for future build-out.
Site Access Access to the parking garage for residential and grocery is provided via a driveway located along S. Elm Street. There are th
three curb cuts located on 13 Street S. and S. Elm Street for loading access and one curb cut on S. Elm Street for the parking garage. The proposed site plan for the redevelopment is shown in Figure 17.
Site Generated Volumes The Institute of Transportation Engineers (ITE) Trip Generation, 8
th
Edition, was used to determine the future trips
generated by the proposed development. A pass-by reduction of 25% was assumed for retail use to account for drivers already on the road that come to the retail stores and then continue in the direction they were originally heading.
Residential Trip Reduction: The site is located on a Metrobus/ART bus corridor on S Eads Street, and there are two Metro stations within a half mile of the site. It is expected that a portion of the residents will arrive by Metrorail, bus, cab or on foot/by bicycle, rather than by personal vehicle. Based on data from Table S-2 of the 2005 WMATA Ridership Survey, residential sites within ¼ mile of a Metro Station have a non-auto mode share of 59%. Table S-3 of the WMATA Survey shows that residential sites within the Beltway have a non-auto mode share of 61%. Therefore, as shown in Table 4, a 60% reduction rate will be applied to the peak hours to reflect the non-auto transit, biking, and walking modes.
Retail Trip Reduction: As noted above, the site is located near many transit options and near many different uses, including residential, office and other retail. Therefore, it is expected that many employees/customers will arrive via modes other than single occupant vehicles. Based on data provided in the 2005 WMATA survey for other retail sites in Crystal City and Ballston, an average non-auto mode share of approximately 69% was observed. In order to provide a conservative analysis, a 50% reduction rate will be applied to the peak hours to reflect the non-auto transit, biking, and walking modes. Table 4 illustrates these reductions.

The above table shows that the proposed development will generate approximately 188 new trips in the weekday morning peak hour, approximately 333 new trips in the weekday afternoon peak hour and approximately 287 new trips in the Saturday peak hour.
Site Trip Distribution The distribution of site trips was based primarily on existing volumes, anticipated traffic patterns and other recent studies conducted in the area. The peak hour trips were calculated and assigned to the roadway network based on the traffic distribution, which is shown graphically in Figure 18. The site generated trips and pass-by trips are shown in Figure 19 and Figure 20.

Traffic Impact Study and Transportation Management Plan – Metropolitan Park 4/5
Future with Development Traffic Volumes In order to determine the traffic volumes on the roadways in the vicinity of the development under the 2017 build condition, the site generated traffic volumes were added to the 2017 future background traffic volumes. The traffic volumes for the total future scenario are shown on Figure 21.
Future with Development Capacity Analysis Capacity analyses were performed at the intersections contained within the study area during the weekday morning, afternoon and Saturday peak hours, under the future with development conditions. Synchro, Version 7.0 was used to analyze the study intersections based on the Highway Capacity Manual (HCM) methodology and include level of service, delay, and queue length comparisons for the turning movements analyzed. As previously mentioned, a peak hour factor of 0.92 was used in the analysis of the future traffic conditions. th
th
It should be noted that signal operation at the intersections of 12 Street S. and S. Eads Street, and 12 Street S. and S. Fern Street was modified from the Synchro files provided by the County to account for the new leg at each of these th
intersections. Permitted left turns were assumed for eastbound and westbound left turns at 12 Street S. and S. Eads Street th
and southbound left turns at 12 Street S. and S. Fern Street. The results of the intersection capacity analyses are presented in Table 6 and are expressed in level of service (LOS) and delay (seconds per vehicle) per lane group. The 95% and 50% queue results for each intersection are also presented in Table 6, and are expressed in feet.

Gorove/Slade Associates
TRANSPORTATION MANAGEMENT PLAN A Transportation Management Plan (TMP) has many components that are tailored to accommodate a given facility with the goal being the reduction of automobile trips by encouraging alternative forms of transportation. A few of the typical TMP components include the establishment of a TMP coordinator, the distribution of transit literature, the establishment of ride-sharing programs, the sale of on-site discounted fare media, and the designation of carpool and/or vanpool spaces. Management measures taken by Metropolitan Park 4/5 can be monitored and adjusted as needed to continually create opportunities to reduce the amount of traffic generated by the site. The Transportation Management Plan shall include a schedule and details of implementation and continued operation of the elements in the plan. The location of the site near the Pentagon City Metro Station allows for a TMP that can include, but not be limited to, the following: Participation and Funding a.
The Applicant will maintain an active membership in Arlington Transportation Partners (ATP), or successor entity at no cost to the developer, on behalf of the property management company.
b.
The Applicant will designate a member(s) of the building management team as Property Transportation Coordinator who will be the primary point of contact and will be responsible for coordinating and completing TDM obligations on behalf of the Applicant. The applicant will provide the name of the Property Transportation Coordinator to the Commuter Assistance Program.
c.
Provide contributions as negotiated with Arlington County staff during the 4.1 Site Plan process.
Facilities and Improvements a.
Provide in the new building one information display with transportation related information for residents, employees and visitors, the content/design/location of which shall be mutually agreeable to ACCS and Applicant.
b.
Maintain one on-site business center in the building (including access to a copier, fax, pc, and internet services), which shall be made available to support building residents.
c.
Comply with requirements of the Site Plan conditions to provide bicycle parking/storage facilities and construction worker parking.
Parking Management Plan a.
Prepare a Parking Management Plan to show how adjacent curb space to the site will be designated for parking and a potential on-street loading zones.
Promotions, Services, Policies a.
Provide Smart Trip cards to residents and/or employees as negotiated with Arlington County staff during the 4.1 Site Plan process.
b.
Provide website hotlinks to CommuterPage.com manager’s websites regarding this development.

Traffic Impact Study and Transportation Management Plan – Metropolitan Park 4/5
CONCLUSIONS The transportation network surrounding the subject site provides excellent regional and local access, and numerous pedestrian and transit options. The site is located in the Pentagon City area of Arlington, Virginia, at the southwest corner th
of 12 Street S. and S. Eads Street. The study area is bounded by S. Eads Street to the east, the future S. Elm Street to the th
th
west, future 12 Street S. to the north and the future 13 Street S. to the south. Regional access to the site is provided via I395 and VA-110 from the north and east, Route 1 (Jefferson Davis Highway) and I-395 to the south and VA-27 and VA-244 th
th
to the west. Immediate access to the site will be provided via S. Eads Street, S. Fern Street, 12 Street S., 13 Street S., 15
th
Street S. and direct access to the parking garage is provided via S. Elm Street. The analysis presented in this report supports the following major conclusions:
Existing Conditions (2012):
The Pentagon City Metro Station is located at the southeast corner of South Hayes Street and 12
th
Street
intersection, less than a quarter (1/4) mile walking distance from the site. The Pentagon City Metro serves both the Blue and Yellow lines.
The subject site is located near several Metrobus and ART bus lines that have stops in the vicinity of the site.
At least nine (9) Metrobus lines; 10A, 16G, 16H, 16W, 9A, 9E, 13B, 13F, and 13G travel through the study area with bus stops located within one block of the site.
Under existing conditions, all intersections operate at acceptable LOS.
Future Conditions Without Development (2017):
With an inherent growth rate of 1% at the study intersections and assumed background development and improvements, all intersections have movements that continue to operate at acceptable LOS under future without development conditions.
Future Conditions With Development (2017):
In order to determine future traffic volumes on the roadways in the vicinity of the subject site under the 2017 build condition, the site-generated traffic volumes were added to the 2017 future background traffic volumes.
The proposed development will generate a total of 188, 333 and 287 net new trips in the morning, afternoon and Saturday peak hours, respectively.
Parking to the site will be accessed by one driveway along Elm Street.
All intersections within the study area operate at acceptable LOS with the proposed Metropolitan Park 4/5 development.
Transportation Management Plan
A TMP will be required for the project based on the County’s requirements. The framework for a TMP is included in this report.
