PROJECT SUMMARY INTRODUCTION

This Traffic Technical Report has been prepared for the U.S. General Services Administration (GSA) to assess and report potential transportation impacts resulting from the proposed consolidation of the U.S. Department of Health and Human Services (HHS) at 5600 Fishers Lane. This site has been previously studied for the consolidation of 2,900 HHS employees in 2010. The planned consolidation has been expanded and now includes a projected total of 4,500 future employees.

The 5600 Fisher’s Lane site is located east by Twinbrook Parkway and bordered by Fishers Lane to the north, and Parklawn Drive to the south. The building is currently partially occupied by HHS and HHS is proposing to consolidate the operations located at several other leased buildings in suburban Maryland into one central location at 5600 Fishers Lane. The employees not currently located at 5600 Fishers Lane are being relocated from four other offices: 540 Gaither Road, 1 Choke Cherry Road, 12300 Twinbrook Parkway, and 801 Thompson Avenue in Rockville, MD. The building is currently undergoing an interior renovation, but total square footage will not be modified. The existing 2,800 HHS employees are projected to increase to 4,500 total employees by the end of 2015.

EXISTING CONDITIONS

Currently, the 2,800 HHS employees are located at 5600 Fishers Lane in Rockville, Maryland. This location is extensively developed with multi-story commercial, retail, and office buildings and parking structures. New construction is underway to the north across Fishers Lane. Four intersections in the vicinity of 5600 Fishers Lane were included in the analysis. Overall, under existing conditions all of the intersections operate at an acceptable level of service (LOS).

FUTURE CONDITIONS ANALYSIS WITH 2,900 EMPLOYEES (NO-ACTION ALTERNATIVE)

The Future Conditions Analysis with 2,900 Employees (No-Action Alternative) examines the future anticipated volumes without taking into consideration traffic that would be generated by the collocating an additional 1,600 employees to the site. This analysis includes the existing traffic volumes, and approved un-built developments in the study area. The No-Action Alternative analysis also takes into account any funded infrastructure improvements in the study areas.

Under the No-Action Alternative, two of the intersections are anticipated to operate at an unacceptable LOS. The intersection of Twinbrook Parkway at Veirs Mill Road (MD 586) is anticipated to operate at an unacceptable LOS in the morning and evening peak hours. The intersection of Twinbrook Parkway at Rockville Pike (MD 355) is anticipated to operate at an unacceptable LOS in the evening peak hour.

FUTURE CONDITIONS ANALYSIS WITH 4,500 EMPLOYEES (ACTION ALTERNATIVE)

The Future Conditions Analysis with 4,500 Employees (Action Alternative) examines future anticipated volumes taking into consideration traffic under the No-Action Alternative as well as

HHS Lease Consolidation Traffic Technical Report Project Summary traffic that would be generated by collocating 4,500 HHS employees at the 5600 Fishers Lane site. Under the Action Alternative Analysis, the number of employees to be collocated would constitute an increase of approximately 1,600 employees from the No-Action Alternative.

Under the Action Alternative, three of the intersections are anticipated to operate at an unacceptable LOS for one or both peak hours. The intersection of Twinbrook Parkway at Veirs Mill Road (MD 586) is anticipated to operate at an unacceptable LOS in the morning and evening peak hours. The intersection of Twinbrook Parkway at Parklawn Drive is anticipated to operate at an unacceptable LOS in the evening peak hour. The intersection of Twinbrook Parkway at Rockville Pike (MD 355) is anticipated to operate at an unacceptable LOS in the evening peak hour.

HHS EMPLOYEE COMMUTER SURVEY

An online survey of existing HHS employees was conducted to determine the commuting patterns of the employees and how they might change after the consolidation. The survey examined the modes by which employees travel to work, working hours, telecommuting, origin/destination, possible improvements to transit options, and reasons for mode choice.

CONCLUSIONS AND MITIGATION

The results of the study show that the collocation of 4,500 HHS employees to the 5600 Fishers Lane site will have an adverse impact on traffic conditions in the area. Discussions with Montgomery County Planning Staff indicated that the interior renovation of 5600 Fishers Lane does not require a traffic mitigation agreement. However, in order to help mitigate the adverse impact of the added trips on local roadways, HHS should hire a Transportation Management Coordinator and develop a Transportation Management Plan (TMP). The TMP would identify strategies for reducing the number of single occupancy vehicles which will access the site and encouraging alternate modes of traveling, thereby improving traffic conditions in the area.

HHS Lease Consolidation Traffic Technical Report Introduction

CHAPTER 1: INTRODUCTION

This Traffic Technical Report has been prepared for the U.S. General Services Administration (GSA) to assess and report potential transportation impacts resulting from the proposed consolidation of the U.S. Department of Health and Human Services (HHS) at 5600 Fishers Lane. This site has been previously studied for the consolidation of 2,900 HHS employees in 2010. The planned consolidation has been expanded and now includes a projected total of 4,500 future employees by the end of 2015.

The subject site is located east of Twinbrook Parkway and bordered on the north by Fishers Lane and on the south by Parklawn Blvd, as shown on the map below. The building is currently partially occupied by HHS. HHS is proposing to consolidate several other leased buildings into one central location at 5600 Fishers Lane. The employees not currently located at 5600 Fishers Lane are being relocated from four other offices: 540 Gaither Road, 1 Choke Cherry Road, 12300 Twinbrook Parkway, and 801 Thompson Avenue in Rockville, MD. The building is currently undergoing a complete interior renovation, but total square footage will not be modified.

HHS Lease Consolidation Traffic Technical Report Introduction

This study analyzes three scenarios which are as follows: • Existing Conditions (2,800) • Future Conditions with 2,900 HHS Employees (No-Action Alternative) • Future Conditions with 4,500 HHS Employees (Action Alternative)

Discussions with staff from the Montgomery County Planning Department indicated that two tiers of signalized intersections should be analyzed for this study based on the number of additional site generated peak hour trips. Therefore, the following intersections have been analyzed in this study:

1. Twinbrook Parkway at Veirs Mill Road (2nd Tier) 2. Twinbrook Parkway at Fishers Lane (1st Tier) 3. Twinbrook Parkway at Parklawn Drive (1st Tier) 4. Twinbrook Parkway at MD 355 (Rockville Pike)/Rollins Avenue (2nd Tier)

CHAPTER 2: EXISTING CONDITIONS

This section describes the existing transportation facilities in the vicinity of 5600 Fishers Lane, including the traffic conditions and the availability of public transportation facilities.

EXISTING PUBLIC TRANSPORTATION FACILITIES

There are existing public transportation facilities which service 5600 Fishers Lane. These facilities include Metrorail, commuter rail, and bus routes. Below are descriptions of the Metrorail and Marc Rail (commuter rail) systems. Bus routes are described under each of the proposed site conditions.

METRORAIL SYSTEM The Washington Metropolitan Area Transit Authority (WMATA) Metrorail system connects downtown Washington, D.C. to the adjoining areas in Maryland and Virginia (see Figure 2). There are five lines on the Metrorail system which are all connected at some point within Washington, D.C. The Metrorail system opens at 5:00 a.m. on weekdays and at 7:00 a.m. on weekends and closes at 12:00 a.m. Sunday-Thursday and at 3:00 a.m. Friday and Saturday. Trains arrive approximately every six minutes during the peak hours and every twelve minutes during the non-peak hours.

The Metrorail Red Line operates between Shady Grove and Glenmont in Montgomery County. This line has 27 stations and has transfer points with the Orange and Blue Lines at Metro Center and the Yellow and Green Lines at Gallery Place and Fort Totten.

The Metrorail Blue Line operates between Franconia-Springfield in Fairfax County, Virginia and Largo Town Center in Prince George’s County. This line has 27 stations and has transfer points with the Red Line at Metro Center and the Yellow and Green Lines at L’Enfant Plaza. The line runs along the same path as the Yellow Line between King Street and Pentagon and runs along the same path as the Orange Line between Rosslyn and Stadium-Armory.

The Metrorail Orange Line operates between Vienna/Fairfax-GMU in Fairfax County and New Carrollton in Prince George’s County. This line has 26 stations and has transfer points with the Red Line at Metro Center and the Yellow and Green Lines at L’Enfant Plaza. The line runs along the same path as the Blue Line between Rosslyn and Stadium-Armory.

The Metrorail Green Line operates between Branch Avenue and Greenbelt in Prince George’s County. This line has 21 stations and has transfer points with the Red Line at Gallery Place and Fort Totten and with the Orange and Blue Lines at L’Enfant Plaza. The line runs along the same path as the Yellow Line from L’Enfant Plaza to Fort Totten.

The Metrorail Yellow Line operates between Huntington in Fairfax County and Fort Totten in Washington, D.C. This line has 17 stations and has transfer points with the Red Line at Gallery Place and the Orange and Blue Lines at L’Enfant Plaza. The line runs along the same path as the Blue Line between King Street and Pentagon and runs along the same path as the Green Line from L’Enfant Plaza to Fort Totten.

The Metrorail Silver Line is currently under construction and will extend off of the Orange Line tracks near the East Falls Church Station travel to Virginia Route 772 in Loudon County. It is being

Page 3

HHS Lease Consolidation Traffic Technical Report Existing Conditions built in two phases with the first phase consisting of 5 stations and ending on the eastern edge of Reston at Wiehle Avenue. Phase I is anticipated to open in 2014. The second phase will consist of 6 stations including Dulles Airport and is anticipated to open in 2018. The Silver Line will share tracks with the existing Orange and Blue Lines as it travels across the region and will terminate at Largo Town Center.

A new Purple Line is being proposed. The Preferred Alternate would run across Montgomery and Prince George’s County, connecting from Bethesda to New Carrollton. The project is currently in the preliminary engineering phase and is anticipated to complete final design in five (5) years and begin construction once funding is in place.

The Twinbrook Metrorail Station, which is along the Red Line, is approximately 2,300 feet from the entrance to the 5600 Fishers Lane site. The average number of weekday passenger boardings for the Twinbrook Station is approximately 4,569 in 2013.

MARYLAND AREA REGIONAL COMMUTER (MARC) RAIL SYSTEM The Maryland Area Regional Commuter (MARC) Rail System is a commuter rail system that connects Washington, D.C. to the surrounding counties in Maryland and West Virginia (see Figure 3). There are three lines operated by MARC and all of the lines connect at Union Station (which also connects to the Metrorail system).

The MARC Brunswick Line operates between Brunswick, Maryland and Union Station in Washington, D.C. This line also includes extensions to Frederick, Maryland and Martinsburg, West Virginia. This line connects with the Metrorail system at Rockville, Silver Spring, and Union Station along the Red Line. The Brunswick Line operates in the eastbound direction in the morning peak hour beginning at 4:50 a.m. and in the westbound direction in the evening peak hour beginning at 1:30 p.m.

The MARC Camden Line operates between Camden Yards in Downtown Baltimore, Maryland and Union Station in Washington, D.C. This line connects with the Metrorail system at Union Station on the Red Line and Greenbelt and College Park on the Green Line. The Camden Line operates northbound beginning at 6:32 a.m. in the morning peak hour and at 4:13 p.m. in the evening peak hour. It operates southbound beginning at 5:00 a.m. in the morning peak hour and at 3:30 p.m. in the evening peak hour.

The MARC Penn Line operates primarily between Baltimore’s Penn Station and Union Station in Washington, D.C. with four additional stops up to Perryville in Harford, Maryland operating on limited service. It connects to the Metrorail system at New Carrollton along the Orange Line and Union Station along the Red Line. Service along the Penn Line begins southbound at 4:30 a.m. in the morning peak hour. In the northbound direction, service begins at 5:50 a.m. in the morning peak hour.

MARC Rail Brunswick has a station at Rockville which is one station north of the Twinbrook Station along the Red Line.

METROBUS AND MONTGOMERY COUNTY RIDE-ON BUS SYSTEM Several bus routes operated by Metrobus and Montgomery County Ride-On service 5600 Fishers Lane (see Figure 4). The Montgomery County Ride-On route 93 bus is a shuttle, which operates between the Twinbrook Metrorail Station and 5600 Fishers Lane every 30 minutes. Additional bus routes provide service to/from Prince George’s Plaza Metrorail Station, Silver Spring Metrorail Station, Hillandale Shopping Center, Montgomery Mall Transit Center, Glenmont Shopping Center, Rockville Metrorail Station, Rockville Regional Transit Center, Medical Center Metrorail Station, and Shady Grove Metrorail Station. There are bus stops located on both Parklawn Drive and Fishers Lane adjacent to 5600 Fishers Lane.

PEDESTRIAN AND BICYCLE FACILITIES There are sidewalk and pedestrian crossings along the walking route from the Twinbrook Metrorail Station to 5600 Fishers Lane. Also, there are sidewalks along Twinbrook Parkway, Fishers Lane, and Parklawn Drive, which connect to the surrounding residential and commercial areas. The sidewalks vary in width throughout the study area but provide good connectivity. There are marked crosswalks at each of the signalized intersections with pedestrian signals and push buttons. However, only the intersection of Twinbrook Parkway at Rockville Pike (MD 355) has countdown pedestrian signal heads. Additionally, there are some pedestrian ramps that would need to be rebuilt to meet current Americans with Disabilities Act (ADA) guidelines. A signalized pedestrian crossing across Parklawn Drive connects the surface parking lot with 5600 Fishers Lane between Wilkens Avenue and Twinbrook Parkway. There are no dedicated bicycle facilities which connect to the site. Field observations noted bicycles use the sidewalks to travel throughout the study area.

TRAFFIC OPERATIONS ANALYSIS

Montgomery County requires Critical Lane Analysis be performed at critical intersections to determine the Level of Service (LOS) at each location before and after a proposed action. The thresholds in Montgomery County are based on the Policy Area guidelines where the intersection is located. The thresholds for 5600 Fishers Lane site, based on the County requirements, are shown in Table 1 below:

Table 1: Montgomery County Local Area Transportation Review (LATR) Intersection Critical Lane Volume (CLV) Thresholds and Policy Areas

Site Threshold CLV Policy Area

Twinbrook Pkwy at Veirs Mill Road 1,550 North Bethesda

Twinbrook Pkwy at Fishers Lane 1,800 Twinbrook

Twinbrook Pkwy at Parklawn Drive 1,800 Twinbrook

Twinbrook Pkwy at Rockville Pike 1,500 Rockville City

Using the existing traffic volumes collected during October 2013 and the existing lane geometries, an intersection capacity analysis was performed for both the morning (8:00 a.m. to 9:00 a.m.) and evening peak hours (5:15 p.m. to 6:15 p.m.). Analysis was then performed using the Critical Lane Analysis Technique as directed by the Montgomery County guidelines.

The Critical Lane Analysis outputs a LOS, as described in the Highway Capacity Manual (HCM) as a “qualitative measure describing operational conditions Critical Lane Volume (CLV): within a traffic stream, and their perception by The sum of traffic volumes motorist and/or passengers.” In Montgomery County that cross at a single point in the CLV is considered “Acceptable” or “Unacceptable” an intersection. The resulting based on the CLV threshold for the appropriate Policy product is used to determine Area where the intersection is located (see Table 1 for the level of service of an site specific thresholds). It should be noted that while intersection in a Local Area Montgomery County accepts a CLV of 1,800 for the intersections of Twinbrook Parkway at Fishers Lane Transportation Review and Twinbrook Parkway at Parklawn Drive, standard (LATR). industry practices utilize a CLV of 1,600 as acceptable. Therefore, the intersections can be over capacity while still meeting Montgomery County threshold requirements.

Page 8

HHS Lease Consolidation Traffic Technical Report Existing Conditions

The Critical Lane Analysis technique determines the overall operational LOS for an entire signalized intersection. The analysis examines the combination of vehicular streams with conflicting movements during a peak period. The maximum number of conflicts is termed the CLV.

Proposed developments in Montgomery County have to comply with traffic analysis and mitigation measures as stipulated in Local Area Transportation Review and Transportation Policy Area Review Guidelines (LATR & TPAR) (M-NCPPC, 2013) (see Table 1).

The area surrounding the 5600 Fisher’s Lane site is extensively developed with multi-story commercial, retail, and office buildings and parking structures. New construction is underway to the north across Fishers Lane. The Parklawn Cemetery is located to the northeast and wooded areas associated with Rock Creek Regional Park and Rock Creek extend from the north/northeast to the southeast.

The 5600 Fishers Lane site is located between Fishers Lane and Parklawn Drive, just east of Twinbrook Parkway. The main roadways in the vicinity of the site are:

• Veirs Mill Road (MD 586). This is a four-lane divided roadway with a posted speed limit of 40 mph. It runs in an east-west direction. MD 586 carries approximately 46,050 VPD east of Twinbrook Parkway. Its intersections with Twinbrook Parkway and Atlantic Avenue are signalized. • Rockville Pike (MD 355). This is a six-lane divided roadway which runs in a north- south direction and has a posted speed limit of 40 mph. MD 355 carries approximately 52,000 VPD north of Twinbrook Parkway. Its intersections with Randolph Road, Hubbard Drive, Bou Avenue, Twinbrook Parkway, and Halpine Road are signalized. • Twinbrook Parkway. This is a four-lane roadway which widens to a six-lane roadway between Ardennes Avenue and Parklawn Drive with a posted speed limit of 30 mph. Twinbrook Parkway runs in a north-south direction with signalized intersections at Veirs Mill Road, Ardennes Avenue, Fishers Lane, Parklawn Drive, Chapman Avenue, and Rockville Pike. Twinbrook Parkway carries approximately 15,800 VPD east of MD 355. • Parklawn Drive. This is a four-lane roadway with a posted speed limit of 30 mph. Parklawn Drive generally runs in an east-west direction in the vicinity of Twinbrook Parkway. Its intersections with Twinbrook Parkway, Wilkens Avenue, Braxfield Court, and Randolph Road are signalized as well as a signalized pedestrian crossing near 5600 Fishers Lane.

Turning movement counts were collected at the following intersections: 1. Twinbrook Parkway/Veirs Mill Road (MD 586); 2. Twinbrook Parkway/Fishers Lane; 3. Twinbrook Parkway/Parklawn Drive; and 4. Twinbrook Parkway/Rollins Avenue/Rockville Pike (MD 355).

The intersections being studied are based on meeting with M-NCPPC staff, who recommended a two tier approach. The intersections of Twinbrook Parkway at Fishers Lane and Twinbrook Parkway at Parklawn Drive are the First Tier intersections. The intersections of Twinbrook Parkway at Veirs Mill Road and Twinbrook Parkway at Rockville Pike are the Second Tier intersections.

HHS Lease Consolidation Traffic Technical Report Existing Conditions

The existing morning and evening peak hour traffic volumes at these intersections are presented in Figure 5. The raw traffic count data is located in Appendix A of this report. According to information from HHS there are currently 2,800 employees located at the 5600 Fishers Lane site. Thus, the existing traffic count data at that site includes these HHS employees.

Table 2 below presents the CLV Analysis results at each of the study intersections for the morning and evening peak hours. The calculation worksheets are attached in Appendix B. As can be seen in Table 2, all of the study intersections operate at acceptable CLV (CLV<1,500/1,550/1,800) as of October 2013.

Table 2: Existing LOS at Intersections Serving 5600 Fishers Lane, October 2013

In addition, the maximum number of queue lengths during the morning and evening hours was studied. Table 3 this info, as well as, the 95th percentile queues calculated based on the simulation software Synchro. Field observations indicated the southbound left turns at Parklawn Drive exceeded the available storage area in both the morning and evening peak hours. In the morning peak hour, both the southbound movement and the westbound left movement did not clear each cycle at Veirs Mill Road. In the evening peak hour, the northbound movement had excessive queuing at Veirs Mill Road, Fishers Lane and Parklawn Drive in addition to the eastbound movement at Veirs Mill Road.

CHAPTER 3: ROADWAY IMPACTS

The evaluation of the transportation impacts of the proposed collocation of HHS employees at 5600 Fishers Lane was based on the guidelines set forth by Montgomery County. In particular these impacts were evaluated per the Local Area Transportation Review and Transportation Policy Area Review Guidelines (M-NCPPC, 2013) set forth by the Montgomery County Planning Department.

FUTURE CONDITIONS ANALYSIS WITH 2,900 EMPLOYEES (NO-ACTION ALTERNATIVE)

The No-Action Conditions Analysis examines the future anticipated volumes without taking into consideration traffic that would be generated by collocating an additional 1,600 HHS employees. This analysis includes existing traffic volumes, approved but un-built development in the study area, and traffic volumes associated with 2,900 employees as analyzed in the previous traffic study done in conjunction with the 2010 Environmental Assessment. The No-Action Alternative analysis also takes into account any funded infrastructure improvements in the study areas.

FUTURE ROADWAY MODIFICATIONS Montrose Parkway East is part of the Montgomery County Capital Improvement Program. The project consists of a new four-lane divided parkway as recommended in the North Bethesda/Garrett Park and Aspen Hill Master Plans. The roadway will be a closed section with 11-foot wide lanes, a 10- foot wide bike path on the north side, and 5-foot wide sidewalk on the south side. The roadway limits are between the eastern limit of the MD 355/Montrose interchange and the intersection of Veirs Mill Road and Parkland Drive. The project includes a grade-separated interchange at Parklawn Drive and a tie-in to Veirs Mill Road. Construction is expected to start in FY 2018 and will be completed in FY 2021. This project will relieve traffic congestion on roadways in the area through increased network capacity. However, for the purposes of this study, the traffic volumes at the study intersections will not be affected as the construction will not be completed prior to the consolidation of the HHS employees.

BACKGROUND DEVELOPMENTS A list of approved planned developments was obtained from Montgomery County and City of Rockville resources. The developments are graphically presented in Figure 6. Under this No-Action Alternative analysis, it is assumed that these developments will be built out by 2014. Table 4 presents the planned developments and the associated trip generation. The number of vehicle trips generated by these developments was estimated using rates presented in Appendix 1 of the Local Area Transportation Review and Transportation Policy Area Review Guidelines (LATR & TPAR) (M- NCPPC, 2013) for the Montgomery County developments. Trip rates for any developments not covered by these guidelines were estimated using rates documented in Trip Generation, 8th Edition, Institute of Transportation Engineers (ITE, 2008).

In order to determine the impact of these developments on the surrounding roadway network, these trips were distributed to the study area intersections according to the trip distribution percentages presented in Table 4-5 of the LATR & TPAR for Super District 4 in Montgomery County.

HHS Lease Consolidation Traffic Technical Report Roadway Impacts

SHORT-TERM IMPACT TO THE PARKING GARAGE ACCESS Beginning in March of 2014, access to the parking garage at 5600 Fishers Lane will be temporarily moved to Parklawn Drive during the renovations to the building. Vehicles will not be able to access the parking garage via Fishers Lane during this time. This access will be in place for approximately 12 to 18 months. Approximately 650 vehicles are expected to access parking via two adjacent driveways along Parklawn Drive between Twinbrook Parkway and Wilkens Avenue.

Potential short-term impacts from the relocated garage access include increased queuing along Parklawn Drive in both the eastbound and westbound directions at the garage entrance as well as westbound at Twinbrook Parkway. Additional queues may form within the garage as vehicles exit onto Parklawn Drive.

Discussion with Montgomery County Traffic staff have indicated that access at these driveways will need to be limited to right and left turn ingress and right turn-only egress from the garage. Plans for addressing the proposed traffic pattern at these driveways will need to be approved by the county. Additionally, the driveways will need to be monitored for impacts to Parklawn Drive.

The owner would be required to implement any necessary roadway improvements and other potential transportation mitigation measures as a result of the renovations to the 5600 Fishers Lane site as required by Montgomery County.

Figure 6: 5600 Fishers Lane Approved Developments

As previously stated, 2,800 HHS employees are currently located at the 5600 Fishers Lane site. As part of the No-Action Alternative this number is to be increased to 2,900 employees. The number of trips that would be generated under the No-Action Alternative was based on this number. The site trip generation is shown in Table 5.

Figure 7 represents the trip distribution and assignment for the background developments and the site trips generated by collocating 2,900 employees at the 5600 Fishers Lane site. Appendix C contains the trip assignment figures for each of the individual background developments.

No-Action Alternative Traffic Operations Analysis The No-Action Alternative traffic volumes for 5600 Fishers Lane were obtained by combining the existing traffic volumes with the planned development volumes and the site trips for the increase to 2,900 employees at 5600 Fishers Lane. These volumes are presented in Figure 8 and the LOS results are presented in Table 6 below. The CLV calculations sheets are attached in Appendix D.

The intersection of Twinbrook Parkway/Rockville Pike (MD 355 is expected to operate at an unacceptable LOS) during the evening peak hours. The intersection of Twinbrook Parkway/Veirs Mill Road (MD 586) is expected to operate at an unacceptable LOS during both the morning and evening peak hours.

Table 7 presents the projected 95th percentile queues calculated based on the simulation software Synchro for the No-Action Alternative. In addition to the queuing issues seen in the existing condition, it is expected that there will be additional queuing issues for the southbound left and westbound movements at Fishers Lane, the northbound and eastbound through movements and southbound left movements at Parklawn Drive, and the southbound left and westbound through movements at Rockville Pike (MD 355).

FUTURE CONDITIONS ANALYSIS WITH 4,500 EMPLOYEES (ACTION ALTERNATIVE)

The Action Conditions Analysis examines future anticipated volumes, taking into consideration traffic under the No-Action Alternative as well as traffic that would be generated by the proposed collocation of 4,500 HHS employees.

At the 5600 Fishers Lane site, this would constitute an increase of approximately 1,600 employees from the No-Action Alternative. The 5600 Fishers Lane site provides for 1,553 parking spaces between the parking garage and the “South Lot”. It is not anticipated that there will be an increase in parking spaces available; therefore, only one space for every three employees will be provided.

SITE TRIP GENERATION The number of trips that would be generated by collocation of HHS employees at the 5600 Fishers Lane site was based on adding an additional 1,600 employees to the site. The site trip generation is shown in Table 8. The site trip generation for the Action Alternative does not take into account any trip reductions for transit, teleworking, or carpooling in the trip generation. This was done to look at what the impact to the roadway network would be in the worst case scenario and to determine what percentage of trips would need to be mitigated through transit usage, carpooling, teleworking, etc. in order to bring the impact of the consolidation below significant levels. Even though two of the sites that are being consolidated to 5600 Fishers Lane fall within the study area, there trips were included in the trip generation as it is assumed that the existing office locations will be re-occupied.

SITE TRIP DISTRIBUTION Vehicular trip distributions were based upon Table 4-5 of the LATR & TPAR guidelines provided by M-NCPPC for Super District 4, Rockville/North Bethesda as well as proposed site access points and current roadway network.

The trip distribution percentages are presented below:

• 35% to/from the north via Twinbrook Parkway; • 15% to/from east via Parklawn Drive; and • 50% to/from south via Twinbrook Pkwy.

Page 22

HHS Lease Consolidation Traffic Technical Report Roadway Impacts

SITE TRIP ASSIGNMENT The trip generation estimated for the collocation of HHS employees at the 5600 Fishers Lane site was distributed along the study area roadways/intersections based on the trip distribution estimates presented above. The site trip assignment is presented in Figure 10. The site trips were assigned to the network based on parking access from Fishers Lane, Parklawn Drive, and Wilkens Avenue. The proposed parking configuration assumes approximately 1250 parking spaces will be accessible via both Fishers Lane and Parklawn Drive and 300 spaces will be accessed via Wilkens Avenue (see Figure 9). Figure 9 also show the location of the temporary garage access which will be used during the construction process.

ACTION ALTERNATIVE TRAFFIC OPERATIONS ANALYSIS Impacts from the collocation of HHS employees at the 5600 Fishers Lane site were determined by adding the site traffic volumes (Figure 10) to the No-Action Alternative traffic volumes (Figure 8). Intersection capacity analyses were performed at the study intersections and the results are presented in Figure 11 and Table 9.

As can be seen in Table 9, three of the intersections are expected to operate at an unacceptable level under the Action Alternative during one or both peak hours. The Twinbrook Parkway/MD 586 and Twinbrook Parkway/MD 355 intersections are expected to see an increase in the level of unacceptability. Whereas, the intersection of Twinbrook Parkway at Parklawn Drive is expected to operate at an unacceptable LOS in the evening peak hour when it was previously acceptable.

Table 10 presents the projected 95th percentile queues calculated based on the simulation software Synchro for the Action Alternative. Most of the queuing issues expected in the No-Action Alternative would continue to be equal to or worse in the Action Alternative. In the morning peak hour, the southbound left at Fishers Lane is expected to see significant growth in the queue length. In the evening peak hour, the westbound movements are expected to see significant growth in the queue lengths.

HHS Lease Consolidation Traffic Technical Report HHS Employee Commuter Survey

CHAPTER 4: HHS EMPLOYEE COMMUTER SURVEY

An employee survey was conducted via the internet in November 2013 to determine the commuting patterns of the employees and how they might change with the consolidation. The survey was conducted for both the employees already located at 5600 Fishers Lane and those slated to be relocated. The survey was active from November 5, 2013 through November 25, 2013. A copy of the survey is located in Appendix E. The survey investigated the modes by which employees travel to work, working hours, telecommuting, origin/destination, possible improvements to transit options, and reasons for mode choice.

Of the approximately 4,392 employees asked to respond to the survey, approximately 30 percent, or 1,300 employees completed the survey.

SURVEY RESULTS Information was gathered from HHS on the approximate existing mix of employees by office and is shown in Table 11. Based on the survey, Table 11 shows the number of survey respondents by office location. The survey response rates for the offices that will be relocated to 5600 Fishers Lane were much higher than the response rate for the employees currently located at 5600 Fishers Lane. Figure 12 demonstrates where the HHS employees who responded to the survey currently live.

According to the survey, approximately 3 percent of employees indicated that they would relocate their residence if relocated to 5600 Fishers Lane. Most of the respondents who provided the location they would relocate to indicated either North Bethesda or Rockville.

The current mode choice for HHS employees is presented in Figure 13.

Figure 13: Current Mode Choice for HHS Employees

According to the survey approximately 3.5 percent of employees either carpool or vanpool. Table 12 provides a breakdown of the number of days per week the employee is either the driver or a passenger. Carpool and Vanpool users have an average of 2.3 people in their vehicle and an average of 1.8 of the people being HHS employees, including themselves.

Approximately 14 percent of HHS employees travel to work via transit. A majority of the respondents travel along Metrorail’s Red Line with the Shady Grove Station being the most popular boarding station at approximately 20 percent of transit users, followed by Rockville (5 percent). Dupont Circle, Friendship Heights, and Grosvenor on the Red Line are all used by about 3 percent of respondents. Branch Avenue, on the Green Line, is the most heavily used station that is not on the Red Line at a little more than 2 percent of transit users. Martinsburg, WV is the most used MARC station. Figure 14 represents what transit line HHS employees are using based on their boarding station.

Figure 16 shows how long the typical commute is from home to the office for HHS employees.

Figure 16: Typical Length of Commute from Home to the Office

According to the survey results, HHS employees spend approximately $60 on their weekly commute. Approximately 15 percent of respondents indicated they receive a transit subsidy and the average subsidy amount received is $210. Data received directly from HHS resources indicated 10 percent of HHS employees receive Go!Card® subsidies and they receive $193 on average. This indicates that a higher percentage of transit users responded to the survey than non-transit users. Approximately 3.5 percent of respondents are registered with a guaranteed ride home service such as Commuter Connections.

A majority of HHS employees arrive at work between 7:00 am and 9:00 am, with the peak being at 8:00 am. Most employees leave work between 4:00 pm and 6:00 pm with the peak being at 5:00 pm. Figure 17 shows the breakdown of the typical work week schedule.

There is an existing shuttle which is part of the Montgomery Ride-On bus system. It runs on a loop between the Twinbrook Metro Station and 5600 Fishers Lane. Surveyed employees were asked what improvements were needed to the shuttle. Figure 20 displays what improvements the survey respondents thought are needed to the shuttle service. In addition to the improvements listed in Figure 20, several respondents were not aware of a shuttle, indicating a need for increased publicity of the shuttle service. Others would like the shuttle to have a more dependable schedule which corresponds with “on time” work arrivals (:00, :30), text alerts for issues with the shuttle, and a lift for handicap access.

HHS Lease Consolidation Traffic Technical Report Conclusions and Mitigation

CHAPTER 5: CONCLUSIONS AND TRANSPORTATION DEMAND MANAGEMENT MEASURES CONCLUSIONS

HHS is proposing to increase its employee population from approximately 2,900 employees to 4,500 employees by the end of 2015 at 5600 Fishers Lane. This is an increase of 1,600 employees. The collocation of additional employees at the 5600 Fishers Lane site is expected to add approximately 554 trips during the morning peak hour and 592 trips in the evening peak hour.

Traffic conditions at the 5600 Fishers Lane site were analyzed under three different conditions: Existing Conditions, Future Conditions Analysis with 2,900 Employees (No-Action Alternative), and Future Conditions Analysis with 4,500 Employees (Action Alternative). In addition to the vehicular impacts, the availability of transit, pedestrian, and bicycle facilities were studied.

As a result of collocating 4,500 employees at the 5600 Fishers Lane site, traffic is expected to have a moderate impact by changing the CLV from an acceptable level to an unacceptable level at one intersection: Twinbrook Parkway at Parklawn Drive. In addition, traffic is expected to have a moderate impact by further increasing the unacceptable CLV at two intersections which are expected to continue to operate with an unacceptable CLV: Twinbrook Parkway at Veirs Mill Road and Twinbrook Parkway at Rockville Pike.

In order to reduce the impacts at the intersection of Twinbrook Parkway at Parklawn Drive, the number of critical peak hour trips at the intersection would need to be reduced by ten trips in the evening. As shown in Table 14, to achieve this CLV reduction, the number of new employee trips would need to be reduced by 10 percent.

In addition, although the building renovation of the 5600 Fishers Lane site did not require a traffic mitigation agreement or roadway improvements, there are 1,553 parking spaces for 4,500 employees at the 5600 Fishers Lane site and as a result; many HHS employees need to find alternative modes of transportation other than driving alone.

Therefore, in order to mitigate the increased traffic and to mitigate the need for additional parking, HHS would need to hire a full-time Transportation Coordinator to implement a Transportation Management Plan (TMP) that identifies TDM strategies for reducing the number of single occupancy vehicles and encouraging alternate modes of traveling to the 5600 Fishers Lane site. If TDM strategies are implemented to reduce the number of new employee trips by 10 percent, the intersection of Twinbrook Parkway at Parklawn Drive is expected to operate at an acceptable level. The TMP would need to be complete and implemented by the time all 4,500 employees are expected at the 5600 Fishers Lane site, which is expected to be by the end of 2015.

The following TDM strategies should be outlined in the TMP:

TRANSPORATION MANAGEMENT PLAN ASSOCIATION AND TRANSPORTATION COORDINATOR From the employee survey, it appears that employees are unaware of some of the transportation services available. The landlords, tenants, and employees within the immediate vicinity of 5600 Fishers Lane should form a Transportation Management Plan (TMP) Association managed by a Transportation Coordinator. The TMP Association and Transportation Coordinator would work to develop a TMP, identifying Travel Demand Management strategies, implementation procedures and monitoring procedures. The Transportation Coordinator would work with the local transportation authorities to provide necessary services and disseminate information to the HHS employees on transportation options. Information on transit options should be added to the Transportation Services webpage or another centralized location to increase employee awareness of the commuting options. This would include links to bus routes servicing 5600 Fishers Lane, Guaranteed Ride Home Services, and carpool/vanpool options (such as Commuter Connections Ridesharing), etc. In addition, an annual commuter survey should be completed to monitor the commuting habits of HHS employees.

RIDEON BUSES Expansion of the schedule for the current RideOn bus which operates between the Twinbrook Metrorail station and 5600 Fishers Lane (Route 93) should be explored. The current schedule operates between 6:06 a.m. and 9:06 a.m. as well as between 3:37 p.m. and 6:37 p.m. every 30

minutes. Many employees indicated that they would like to see the buses run more often as well as during more hours of the day. In addition, employees indicated they would like the arrival/departure times to better coincide with normal work start and stop times (8:00 a.m., 8:15 a.m., 5:00 p.m., 5:15 p.m., etc.) It is recommended that the HHS Transportation Coordinator work with the North Bethesda Transportation Center and Montgomery County Transit to increase the frequency of the bus route as well as explore expanding the hours of operation.

COMMUTER BUSES Forty two percent of survey respondents indicated that if an express bus was provided for a fee from a Park n’ ride near their home to 5600 Fishers Lane, they would take it. HHS employees are concentrated along the I-270 corridor and many of the survey respondents along this corridor said they would be willing to try a commuter bus. It is recommended that a commuter bus which originates in Frederick, MD and also stops at the Urbana Park and Ride and the Gaithersburg Park and Ride be provided. This commuter bus would terminate at 5600 Fishers Lane. Employees would be more willing to try this option if it terminates at 5600 Fishers Lane, eliminating the need to transfer to Metrorail or MARC as must be done with the existing commuter bus routes. The Transportation Coordinator would work with the Maryland Transit Authority to determine if a route could be established as part of their commuter bus system. Employees would be charged a fee for use of the commuter bus.

PEDESTRIANS AND BICYCLES In order to improve the pedestrian path between the Twinbrook Metrorail Station and 5600 Fishers Lane it is recommended that the pedestrian signals at the intersections of Twinbrook Parkway at Fishers Lane and Parklawn Drive be upgraded to countdown signal heads. Additionally, all pedestrian ramps that are not ADA compliant should be upgraded. The Transportation Coordinator would work with the County to implement these upgrades.

Installation of a Bikeshare Station should be considered at the Twinbrook Metro Station as well as at 5600 Fishers Lane as part of the regional Capital Bikeshare network.

INCENTIVES The addition of a zip-car or other car sharing service at 5600 Fishers Lane may help further incentivize the use of public transit by giving employees the flexibility of having a car when needed during the day. Thirty four percent of survey respondents indicated that needing a car during the day for either work or personal use was a barrier to transit use. This is a potential pool of 1500 employees that could be induced to switch modes from drive alone to transit.

Some options to try and entice more employees to take transit are: adding parking benefits to the Go!Card® program, allowing employees to get both the Bike2Work and Go!Card® subsidy, supplementing the Commuter Connections Guaranteed Ride Home service with additional trips or trips for expanded reasons. In addition, if employees were charged for parking it may incentivize them to take transit. The Maryland Mortgage Program “House Keys for Employees” sponsored by the Maryland Department of Housing and Community Development is another program which may entice employees to purchase a home closer to 5600 Fishers Lane or a form of public transportation.

These incentives should be implemented in order to reduce the number of peak hour vehicle trips to limit the impacts to intersections within the study area as well as reduce the total number of vehicle

trips due to limited parking availability. The Transportation Coordinator would work with the appropriate entities to implement the suitable incentives.
