PREFACE

This report is an update to the previous March 23, 2012 and February 6, 2012 versions of the Transportation Impact Study (TIS) prepared for the development of the former Hine Jr. High School in Southeast, Washington, DC. The TIS was updated to incorporate comments received from the Advisory Neighborhood Commission (ANC) Transportation Subcommittee Working Group and comments obtained from District Department of Transportation (DDOT) on the previous November 23, 2011 Phase 1: Initial Evaluation (TIS scoping document). The following additional updates are included in this report:

• Updated Traffic Analysis to reflect latest development program including below grade retail

• Background Conditions Assumptions - A detailed description of key assumptions for Background Conditions including the regional growth rate and impacts, if any, associated with the planned office additions at 325 7'" Street, S.E and 327 7'" Street, S.E.

• Site Traffic- Inclusion of daily Hine site traffic projections (in addition to peak hour traffic provided in previous iteration of the report) and a figure to illustrate new site-related trips at each intersection.

• Bicycle counts - Inclusion of bicycle count data conducted during peak bicycle activity between April and October.

• Expanded Safety Analysis - Inclusion of crash data indicating the number of accidents per location and specific measures to address the concern for pedestrian/vehicular conflicts at the parking garage and the loading dock driveway.

• Heavy Vehicle counts- Summary of 7'" Street truck count results.

• Expanded Study Area- Inclusion of qualitative traffic analysis of the 9'" and C Street intersection.

• Additional Alley Observations - Summary of additional alley observations conducted on a Monday (understood to be a higher day of loading and trash activity).

• Parking Spillover- Summary of potential impacts to on-street parking.

Retail Land Use Options and Report Assumptions

The Hine Jr. High School site will include a mix of residential, office and retail components. The site plan allows for the flexibility to provide below-grade retail uses such as a grocery store, pharmacy or a health club, depending on leasing opportunities. For the purposes of this report, the retail option that would generate the highest level of traffic was analyzed, representing the worst case scenario. The grocery store option was projected to have the highest level of traffic compared to a health club or a pharmacy.

INTRODUCTION

Purpose of Study

The following report is a Transportation Impact Study (TIS) prepared for the development of the former Hine Jr. High School (herein Hine School site) in Southeast, Washington, D.C. Figure 1 illustrates the site location.

The Stanton-EastBanc team is planning a mixed-use development at the Hine School site. The Property is bounded by , S.E. and a small portion of D Street, S.E. to the south, an east-west public alley located at the southern end of Square 900 to the north, 7th Street, S.E. to the west and 8th Street, S.E. to the east.

The applicant proposes to develop the property with two buildings (a north and a south building) that will contain a mix of uses including the following:

• 158 residential units • 162,373 square feet (SF) of office space • 61,667 square feet of ground floor and below-grade retail space • 19,879 SF Grocery Store'. Pharmacy or Health Club (including 5,144 SF at grade and 14,735 SF below grade) • 41,788 SF Specialty Retail (34,390 SF at grade retail and 7,398 SF below grade north building)

The development will provide approximately 320 below grade parking spaces. The project will also include a number of transportation improvements such as re-introducing the currently closed section of C Street (between 7th Street and 8th Street), improved pedestrian environment with streetscape and public plaza area and bicycle parking as highlighted in the Transportation Improvement section of this report. The project is planned to be complete by fourth quarter of 2015.

The purpose of this traffic study is to evaluate the transportation and traffic impacts associated with the development of the High School site.

1 The site plan allows for the flexibility to provide below-grade retail uses such as a grocery store, pharmacy or a health club, depending on leasing opportunities. For the purposes of this report, the retail option that would generate the highest level of traffic was analyzed, representing the worst case scenario.

Pedestrian Conditions

Sidewalks and crosswalks provide access to the Hine School site. A summary of observations are as follows:

• Sidewalks are provided along all roadways within the study area. Approximate sidewalk widths along some of the roadways is as follows:

o 7th Street: 9-feet wide including 5 foot tree box8 o 8th Street: 11-feet wide including 5 foot tree box o D Street: 8-feet wide including 3 foot tree box o Pennsylvania Avenue: 18-feet wide including 5 foot tree box

• Marked crosswalks are provided at all the study area intersections. Some locations provide high visibility crosswalks such as the 8th Street, SE/ C Street, SE intersection and along Independence Avenue, SEat 7th Street, SE.

• Pedestrian generators within close proximity to the Hine School site include the Eastern Market Metrorail Station, Eastern Market, DC's Flea Market (operated within Hine School property on weekends), 7th Street shops and Barracks Row commercial area on 8th Street.

• The large median along Pennsylvania Avenue, SE serves as refuge between the pedestrian and motorist. It is however noted, pedestrians were observed crossing Pennsylvania Avenue (mid-block between 7th Street and 8th Street) instead of within the designated crosswalk. The mid-block crossing is the most direct route for some pedestrians.

• Pedestrian counts were conducted at all 14 study area intersections during the weekday AM and PM peak hours. Weekend pedestrian counts were also conducted at the designated weekend intersections. A summary of peak hour pedestrian counts surrounding the Hine School site is as follows:

o Weekday • 7th Street (at Pennsylvania Avenue) -476 AM and 391 PM • 8th Street (at Pennsylvania Avenue)- 485 AM and 439 PM • Pennsylvania Avenue ( at 8th Street) - 368 AM and 255 PM • C Street ( at 7th Street) - 116 AM and 205 PM

o Weekend • 7th Street (at Pennsylvania Avenue) - 3556 • 8th Street (at Pennsylvania Avenue) - 848 • Pennsylvania Avenue ( at 8th Street) - 1248 • C Street ( at 8th Street) - 593

• There are ADA curb ramps and landings at all study area intersections.

Bicycle Facilities Inventory

The following designated bicycle facilities are located within close proximity to the Hine School site:

• Bike Lanes on 4th,6th, 11th, 14th and 15th Streets, SE, North Carolina Avenue, SE, East Capitol Street, SE and Massachusetts Avenue, SE • Signed Bike Route on 11th Street, SE (South of Pennsylvania Avenue) • Anacostia Riverwalk trail

Figure 5 illustrates the above listed bicycle facilities.

A summary of peak hour bicycle counts along intersections surrounding the Hine School site are as follows:

o Weekday • ?th Street (at Pennsylvania Avenue) -17 AM and 10 PM • 8th Street (at Pennsylvania Avenue)- 22 AM and 20 PM • Pennsylvania Avenue (at 8th Street)- 33 AM and 29 PM • C Street ( at 8th Street)- 13 AM and 10 PM

o Weekend • ?th Street (at Pennsylvania Avenue) - 27 • 8th Street (at Pennsylvania Avenue) - 48 • Pennsylvania Avenue ( at 8th Street) - 62 • C Street ( at 8th Street) - 12

On roadways without designated bicycle facilities, bicyclists are expected to either utilize the sidewalk or the vehicular travel lanes, as typically observed throughout areas within the city, to directly access the project.

There are five single u-shaped bicycle racks located at the north end of the Eastern Market near the corner of North Carolina Avenue and 7th Street, SE. Capital Bikeshare has two existing Eastern Market bike stations, one along Pennsylvania Avenue, SE near the entrance to the Eastern Market Metrorail Station and one along North Carolina Avenue, SE at 7th Street, SE. Each station stores fifteen bikes. Capital Bikeshare locations are shown in Figure 5.

The 2008 District of Columbia Bicycle Map rates traffic conditions for bicycling near the Hine School site as poor on Pennsylvania Avenue, SE. Traffic conditions for bicycling on 8th Street, SE and on Independence Avenue, SE are rated as fair.

Hine Existing Parking

There are two surface parking lots within the Hine School property boundaries. The first lot provides approximately 30 permit parking spaces which are currently used on Weekdays by the Community Action Group (GAG) and the Mayor's Department of Environment. Since both the GAG and the Mayor's Department of Environment will no longer use the Hine School site existing Weekday parking demand (associated with GAG and the Mayor's Department of Environment) will be relocated to an alternate site. The second and larger surface lot of the two holds approximately 64 parking spaces. During the Weekday this parking lot provides temporary overflow parking for the local community and Eastern Market, and on Weekends houses the Flea Market. Existing Weekday observations of this surface parking lot indicated 31 of the 64 parking spaces (or 48 percent) were occupied at 2:30PM. At 6:30PM, there were 12 vehicles parking in the parking lot. Weekday community use of the parking lot will also be displaced.

On-Street Parking

Parking surveys were conducted to determine on-street inventory, occupancy, parking restrictions and parking control within the Hine parking study area. Roadways where curbside parking could potentially be impacted by the site design or by site trips were included in the parking survey area (shown in Figure 6). Additionally, per community requests, the parking survey area was extended north 9 to A Street, SE to understand weekend parking demand on neighborhood streets associated with the Eastern Market and the Flea Market.

Weekday parking occupancy surveys were conducted in late January 2011 on a weekday (Tuesday through Thursday) during the afternoon peak (2:30PM to 3:30 PM) and during the evening peak (6:30 PM to 7:30 PM). Weekend parking surveys were conducted on a Saturday from 12 PM to 2 PM. A summary of parking supply and control is provided in Table 2. Table 3 summarizes occupancy and observed demand for each survey period.

On-street parking near the Hine School site services retail and commercial uses and neighboring residents and visitors. Adjacent to the property, there are 15 metered parking spaces along the eastside of 7'" Street, SE, 15 metered parking spaces along the west-side of 8th Street, SE and 2 un-metered parking spaces along D Street, SE (southern border of site between 8th Street, SE and Pennsylvania Avenue, SE). Curb parking is prohibited along Pennsylvania Avenue, SE along the frontage of the property.

ALLEY NETWORK AND OBSERVATIONS

Access and circulation

The existing east-west public alley (the northernmost border of the site) is I!No-way and is used by 8th Street residents, cut-through traffic, delivery vehicles (associated with the commercial/retail uses on 7'" Street, SE), trash trucks and pedestrians. Vehicular and truck traffic enter the alley from 7'" Street and 8th Street. Delivery vehicles park in the east-west alley, on both the north and south sides, to unload goods. Truck drivers often park in the alley and cart deliveries to commercial/retail businesses along 7'" Street, SE. On Weekends, the 71" Street access is closed. Truck traffic was observed using the 8th Street driveway for ingress and exiting the alley by reversing out onto 81" Street. The east-west alley is approximately 20 feet wide.

A separate north-south alley (which connects to the east-west alley) provides rear access to residential properties (fronting 8'" Street, SE) and commercial/retail businesses along 7'" Street. This north-south section is quite narrow, approximately 10 feet wide, and supports one lane access (primarily used for automobiles only).

See Figure 7 for an illustration of the alley nei!Nork and existing access points.

As shown in Figure 8, there was a maximum of four trucks in the alley at any one time. The median duration of stay in the alley was 13 minutes. The average length of stay was 16.4 minutes. The peak activity period was between 7:45AM and 8:15AM.

The figure also identifies (see circled areas in figure 8) two time periods where three or more trucks were using the alley at any one time. Between 7:53AM and 7:54AM there were four vehicles (one medium truck, two trash trucks and a street sweeper) parked in the alley. In the 9:00 AM hour, there were two large trucks (55 foot) and one small truck parked in the alley from 9:06AM to 9:07AM. The longest duration that any two trucks were parked in the alley was approximately 20 minutes between 7:40 AM and 8:00 AM and then between 8:45AM and 9:05AM.

Additional alley observations were conducted on Monday April 23, 2012 from 7:00AM to 10:00 AM. The additional counts were conducted per community comments suggesting more loading and trash collection occur on Monday. A total of two trash trucks were observed using the east-west alley to pick-up trash during the three hour observation period. No delivery vehicles were observed during the observation period. This activity was significantly less than what was observed during the Tuesday observations.

Data Collection and Field Observations

Weekday

Weekday data (traffic, pedestrian and bicycle) collection 18 and field observations were conducted for the study area intersections from 7:00AM to 9:00AM and from 4:00PM to 6:00 PM on the following dates:

• December 2, 2010 • December 7, 2010 • December 9, 2010 • March 9, 2011 • March 15, 2011 • April17, 2012

Truck counts were conducted along 7'" Street and along 81" Street to determine the percentage of heavy vehicle traffic during the peak hours. Those counts indicated the following:

• 2 % of northbound and southbound traffic along 7'" Street traffic were heavy vehicles

• 8 % of northbound 8'" Street traffic were heavy vehicles and 10 percent of southbound 81" Street traffic were heavy vehicles.

The heavy vehicles percentages along 8'" Street were higher than the 2% default19 and were taken into account in the intersection and corridor analyses.

Based on data collected during the observations time periods, the system peak hours were determined to be 7:45AM to 8:45AM and 5:00PM to 6:00PM. Existing Weekday peak hour traffic is shown in Figure 10.

During the September 20, 2011 Preliminary Zoning Review Meeting (PZRM), DDOT requested the Weekday evening count period be extended by one hour from 4:00 PM to 7:00 PM (instead of 4:00 PM to 6:00 PM). An additional intersection count was conducted at the 8'" Street, SE and Pennsylvania Avenue, SE intersection to determine if the peak extended after 6:00 PM. The additional traffic count confirmed the peak hour was from 5:00 PM to 6:00 PM.

" Bicycle counts were conducted during the time of traffic counts at each intersection however additional bicycle counts were conducted in April2012 to replace December 2010 bicycle count data as outlined in the Bicycle section of the report 19 Typically used in analysis procedures.

Existing Intersection Analysis

To assess existing traffic conditions , it is necessary to collect traffic data at the intersections during peak periods of traffic flow and operations (i.e. morning and evening rush hour periods). The data collected is in the form of turning movement counts for through , left and right movement at the in tersection. This existing data , along with other operational parameters such as the number of lanes, heavy vehicle percentages, and information on traffic signal timing , is entered into traffic analysis software and evaluated to provide a l evel of Service (LOS) at each intersection.

Level of Service (LOS) is a measure of the average control (i.e. stop sign or traffic signal) delay experienced by all motorists arriving to an intersection. There are six representative levels of service defined for intersections and they are designated using letters A through F, with LOS A representing the best operating conditions and LOS F representing the worst. LOS "E" is typically accepted by DDOT as the minimum delay threshold limit for intersections.

Level of Service is defined separately for signalized intersections and unsignalized intersections. For signalized intersections , delay is evaluated for the overall intersection; wh ile at unsignalized intersection delay is ana lyzed for each movement separately (i.e. northbound, southbound , eastbound or westbound traffic). The thresholds for the intersection levels of service are shown in Table 5.

TABLE 5: Intersection Level of Service T hreshold for Delay

SYNCHRO 7 software was used to calculate LOS Capacity analysis for the morning and evening peak hours of a typical weekday .

Tables 6 and 7 provide weekday and weekend LOS results for the study area intersections under existing conditions.

As shown in Table 6, all of the study area intersections currently operate at acceptable LOS except for the unsignalized intersection of 8th Street, SE and D Street, SE (north of Pennsylvan ia Avenue) . During the AM peak hour, the intersection operates at a LOS F with an average delay to motorists of 65.4 seconds per vehicle. The intersection delay is experienced only by motorists on D Street, SE . Motorists on 8th Street, SE do not have to stop and therefore do not experience delay at the intersection.

Weekend capacity analys is (shown in Table 7) indicates all study area intersections operate within the acceptable threshold . Field observations showed congestion along southbound 8th Street was prevalent for short periods during the peak hour with traffic queuing back from Pennsylvania Avenue , SE to C Street, SE .

Existing Corridor Analysis

For the corridor analysis, factors or roadway characteristics such as traffic data and signal timing data (similar to the intersection analysis factors) are entered into the software . However, the corridor analysis also includes observed speeds and the time it takes to travel from the starting point of the corridor to the ending point of the corridor. A LOS for corridor analysis is based on travel time and average speed (instead of average delay which is the measure for intersection analysis). The corridor analys is was conducted along 8th Street from North Carolina Avenue to Pennsylvan ia Avenue and along Pennsylvania Avenue from 6th Street to gth Street. 81h Street was selected since a higher volume of heavy veh icles (8%), buses and fire tru cks also frequent the roadway.

Urban street segment LOS methodology was used to analyze Pennsylvania Avenue and 8th Street for the Weekday AM and PM peak hour. Urban street segment LOS is based on the average through-vehicle travel speed . The average speed is calculated from the travel time on the street segment and the control delay of the through movements at any signalized intersection. The control delay at the signalized intersections includes the delays of deceleration, stops , and re-acceleration.

The urban street LOS is calcu lated in four steps :

1) Determine the street class by field measurement or assessing the streets design category (Class I to IV). ZONING COMMISSION District of Columbia

33 Case No. 11-24 115D2 Hine Jr. High School Site Development Traffic Impact Study Washington, D.C. April 30, 2012

2) Determine the time requ ired to drive the street segment. This was performed in the field using the floating car methodology in which a car is driven along the segment severa l times and the mean travel time is computed .

3) Calculate the delays imposed on through traffic by any traffic signa ls in the street segment.

4) Calculate average travel speed .

The range of free flow travel speed and corresponding Urban Street Class categories is shown in Table 8.

TABLE 8: Urban Street Class Categories

The speed limit is 30 miles per hour (mph) on Pennsy lvania Avenue and 25 mph on 81h Street. The urban street class for 81h Street and Pennsylvania Avenue is Class IV. The LOS for each Urban Street Class category is shown in Table 9.
