Existing Transportation System

< Please Open Page for Additional Text Transportation System Existing Transportation System This section describes vehicular transportation associated with Children s. Pedestrian and other nonmotorized transportation is described in a separate section of this submittal. Children s is a regional leader among effective Commute Trip Reduction (CTR) and Transportation Management Plan (TMP) programs. The 2006 TMP Report demonstrated that fewer than 38 percent of affected day-shift staff drive alone to work. Children s offers a variety of transportation tools to serve diverse transportation needs. These tools include a fully subsidized FlexPass program, on-site Zipcars, carpool and vanpool formation, priority HOV parking, Guaranteed Ride Home, bicycle parking and shower/locker facilities, parking charges and commute bonus incentives for alternative commuters. Children s has used remote parking sites to reduce vehicle congestion on campus and the surrounding streets. Both pedestrians and vehicles share the use of Penny Drive. Children s manages this by enforcing speed limits, directing traffic and providing valet parking. Hospital Campus Access Sand Point Way NE is the primary arterial serving Children s. The hospital campus entry is at the signalized intersection of Sand Point Way NE and Penny Drive. Most vehicle trips related to hospital operations use this access point to Penny Drive. The second access point to the campus is a driveway from NE 45th Street near the southeast corner of the campus. This is a secured access point that is not available to the public. Service vehicles can enter the Whale Garage via a secured gate. In addition, an apron at this location allows Metro buses to lay over on Children s property. This entrance also provides access to a fire lane on the south side of the Melinda French Gates Ambulatory Care Building. Traffic Penny Drive distributes vehicles to all parking areas, entry points and loading docks. The roadway has two through-lanes with a two-way center turn lane and 10-mph speed limit. At-grade crosswalks are located along Penny Drive, connecting the parking and campus facilities areas to the north with the primary hospital areas to the south. Parking Children s currently provides 1,462 parking on campus. The existing Giraffe Garage provides parking for patients, visitors, staff and physicians. The garage has four levels, which are not currently interconnected with ramps between floors; direct access to each level is via separate garage entrances off Penny Drive. The Giraffe Garage is located on Penny Drive across from the hospital. ADA-accessible parking is located at the Janet Sinegal Patient Care Building entry plaza. The existing three-level Whale Garage serves the main entrance of the Melinda French Gates Ambulatory Care Building and provides direct access to ADA-accessible parking. Automobile access to the Whale Garage is primarily from Penny Drive, although a secured service access is located off NE 45th Street. One hundred and two surface parking provide parking for the Emergency Department, patient/family motor homes and other visitors. The number of surface parking has been reduced due to interim modular office units and landscape maintenance operations. Shuttles Shuttles provide access to Children s off-campus parking as well as off-campus work locations, and operate from 5:30 a.m. to 9 p.m., Monday through Friday. During peak commuting hours, two shuttles serve each lot; during offpeak commuting hours, a single shuttle serves each lot. On campus, the Children s shuttle drops off shuttle riders at the Giraffe Entrance. Frequent weekday shuttle service is provided to off-campus parking locations. Shuttles also serve interfacility transportation needs between Children s main campus and other Children s facilities in Seattle. The service reduces traffic and parking congestion. Two shuttles run between the hospital campus and Children s Met Park West site in downtown Seattle. A third shuttle runs every hour to Children s research facility in downtown Seattle. The Seattle Cancer Care Alliance (SCCA) shuttle runs every 40 minutes to the University of Washington, where it connects to service to the SCCA in South Lake Union. Guest services transportation is provided to patients and families via a separate fleet of ADA-equipped vehicles. Transit The hospital campus is served by Metro Transit routes #25 and #75. By funding a partnership with Metro, Children s succeeded in having both routes enhanced in fall 2007 in an effort to reduce single-occupant vehicle use to the hospital. This $250,000-per-year investment provided service at least every 30 minutes on route #75 throughout the entire service time span, enhancing service greatly during shift-change times. The #75 serves the main entrance of the campus on Sand Point Way NE. Sheltered bus stops are located in both the northbound and southbound directions, and an ADA-accessible ramp system provides access from Sand Point Way NE to the Giraffe Entrance. The #25 serves the secondary access point of the campus, along NE 45th Street. A single, sheltered bus stop on Children s property serves both incoming and outgoing trips. A covered, ADA-accessible walkway through the Whale Garage provides access to the Whale Entrance. Deliveries and Service Traffic Most deliveries are handled at two separate loading docks, one for general receiving and one specifically for food deliveries. Neither loading dock is configured to allow larger trucks to turn around. Therefore, most delivery and service vehicles must back in from Penny Drive. Off-Campus Vehicular Access Access for vehicles to the hospital campus is via the signalized intersection of Sand Point Way NE and Penny Drive. It is served by left-turn lanes without dedicated signal phases for left turns from any approach. The next nearest signalized intersection is located to the south, at Sand Point Way NE and NE 45th Street. Other important intersections providing neighborhood accessibility to Sand Point Way NE are not signalized, including 40th Avenue NE and NE 50th Street. Hartmann The Hartmann building is located on Sand Point Way NE, south of the main Penny Drive campus access, near 40th Avenue NE. Traffic flows one way from an entrance at the north end of the property (opposite 40th Avenue NE) to an exit at the south end of the property. Neither access point is signalized. A two-way center turn lane facilitates traffic to and from Sand Point Way NE. Eighty parking are provided for patients, staff and physicians in a surface lot. While the Hartmann building is bound on the north by the Burke-Gilman Trail, there is currently no direct access from the trail to the Hartmann property. Metro Transit route #75 serves the Hartmann building via Sand Point Way NE. An unsheltered southbound bus stop is located directly in front of the building. In the northbound direction, an unsheltered bus stop is located across Sand Point Way NE. See Figure 31, Existing Transportation and Parking. 76

Comprehensive Safety and Mobility Plan Children s has long recognized the complex transportation issues facing the region, and northeast Seattle in particular. In response, the hospital has established an award-winning transportation management program that has substantially reduced the number of employees driving alone to work. Among daytime employees affected by Washington s Commute Trip Reduction (CTR) law, the percentage traveling to campus via singleoccupant vehicle (SOV) fell from 73 percent in 1995 to a remarkable 38 percent in 2007. This accomplishment is significant both for a hospital and for an employer located in a neighborhood with limited public transit service. Children s is committed to surpassing its past successes in reducing vehicle traffic and to improving the health and safety of the hospital community and local residents. To this end, Children s has developed a Comprehensive Safety and Mobility Plan (CSMP) that would mitigate vehicle traffic related to MIMP expansion by shifting even more employees and visitors from SOV to bicycling, walking, shuttle, and transit. The CSMP would allow Children s to: Match the 2020 Seattle comprehensive plan mode-share goal for the University District of 30 percent SOV rate 1. Reduce the need to build parking on campus or in nearby facilities within the area that would be affected by MIMP-related vehicle trips. Support Children s continued leadership in delivering innovative transportation solutions in the context of climate change. The CSMP would take a three-pronged approach: 1) enhancing the Transportation Management Plan (TMP), including on-site programs, parking management policies, and shuttle service; 2) investing in projects to improve bicycle and pedestrian access and safety to Children s campus and in the surrounding neighborhood; and 3) identifying and investing in on- and off-site capital improvements that enhance person travel capacity and improve overall mobility in the area. At the April 2008 CAC meeting, Children s elaborated on the CSMP by committing to: 1. Reach University District mode-split goal for 2020 of 70 percent non-single-occupancy vehicles. This will be achieved by providing shuttle buses to regional transit hubs, innovative bike programs and parking management. 2. Invest up to $2,000,000 for bicycle and pedestrian safety improvements on key connections and facilities. 3. Lead a partnership to improve mobility and safety in its vicinity. This will include contribution of up to $500,000 seed money for study. Based on the study, Children s will fund its share of selected corridor and intersection projects, amount to be determined. A subsequent CAC transportation workshop on May 6, 2008, led to additional comments and suggestions which are under consideration and will be included in the Final Master Plan. Transportation Management Program Children s will continue to build upon its award-winning CTR and TMP programs. Children s will work with local and regional partners, such as Community Transit, Metro, Sound Transit and Seattle Department of Transportation, to collaborate in minimizing single-occupancy vehicle commute trips in the area and to maintain and enhance its role as a leader in institutional transportation demand management in the Pacific Northwest. Day shift employees affected by the Washington State Commute Trip Reduction (CTR) law as reported in the CTR survey 78

TMP Enhancements Proposed TMP enhancements include: Shuttle connections to transit. New shuttle service will extend the reach and convenience of the public transit system by connecting employees between major transit hubs and Children s facilities. Transportation demand management enhancements. Expanded services and incentives include offering benefits to more staff and increasing financial awards for non-sov commutes. Parking Management. New policies will increase parking fees for SOV, assign staff to offcampus lots based on proximity to home addresses, and implement enhanced technology to improve parking management. TMP program elements are standard for all Draft Master Plan alternatives. Off-Site Enhancements In response to impacts identified in the Preliminary Draft EIS, Children s is committed to collaborating with the City of Seattle and area partners in order to identify potential off-site capital projects designed to improve person-movement capacity, person travel time, and safety. In conjunction with MIMP approval, Children s would fund a Sub-area Safety and Mobility Study to be led by the City. Study partners, including Children s, would commit to funding a share of selected projects. These projects would be evaluated based on whether they could be expected to improve the capacity for the transportation system to move people quickly and safely through the area, primarily by enabling those travel modes promoted by the TMP. Children s would commit to funding a portion of the projects identified by the Safety and Mobility Study. In partnership with Sub-area Safety and Mobility Study partners, Children s would also commit to funding a share of additional projects aimed at improving HOV and transit travel on the target corridors. Partners in the Study would identify capital projects that: Are tailored to achieving greater person travel capacity and improved person travel times, rather than improving general capacity or travel times for single-occupant vehicles Mitigate the impact of the MIMP on regional and local traffic Support City of Seattle and sub-area transportation goals, including the Mayor s initiative to make Seattle the most walkable and bikeable city in the country Are deemed feasible, including full funding for such project Offer a cost-effective solution Garner community acceptance Provide benefit to the widest range of people within the community, including Children s employees, patients, and visitors Potential capital investments might: Fill gaps in the nonmotorized transportation network by completing bike infrastructure and sidewalks, creating connections to the Burke-Gilman Trail, and enhancing intersection safety Enhance the ability of HOV, transit and shuttle vehicles to move through nearby corridors via signal treatments, dedicated lanes and intersection design Through the CSMP, Children s seeks to continue its leadership role in finding regional transportation solutions. The CSMP comprises a multimodal access and mobility strategy designed to make nonmotorized transportation (i.e., biking and walking) and transit the primary and most attractive ways for employees and staff to get to campus. This CSMP approach would be the same for any design alternative. In addition, Children s would invest up to $2.0 million to projects that support bicycle and pedestrian safety and access to the hospital and the surrounding communities. DRAFT MASTER PLAN for Children s Hospital and Regional Medical Center 79

< Please Open Page for Additional Text On-Site Capital Improvements Nonmotorized Access and Connections Making nonmotorized transportation safe, attractive and time competitive with SOV travel is a guiding principle of the transportation elements for the MIMP alternatives. Nonmotorized solutions include clear, safe pedestrian circulation routes from nearby neighborhoods, transit and shuttle stops, end-of-trip amenities such as bicycle racks and showers for cyclists and walkers, and safe and intuitive connections between buildings and parking garages. Pedestrians and Bicyclists, Alternatives 3/6 Pedestrians and bicyclists would enter campus primarily via Penny Drive. Access points would also be provided on NE 50th Street and NE 45th Street. Users of the Burke-Gilman Trail would access campus using adjacent surface streets (NE 50th Street) to Penny Drive. Pedestrians and Bicyclists, Alternative 7 Pedestrians and bicyclists would primarily enter campus via the 40th Avenue NE entrance with NE 45th Street as an alternative. This alternative would allow for the development of a direct connection to the Burke-Gilman Trail through the northern portion of the Hartmann property. Trail users would have direct, level-grade access to safe crossing of Sand Point Way NE at 40th Avenue NE using the new signalized intersection that will be installed by the Seattle Department of Transportation in the fall of 2008, access to the hospital s front door entrance, and trip-end amenities on campus. Public Transit and Shuttle Buses, Alternatives 3/6 Up to four to six bays will be provided at the Giraffe entrance to accommodate parking and in-service layover of shuttle vehicles. Shuttles will enter and exit campus via Penny Drive. Adequate space will be programmed for on- or off-site fleet storage and maintenance facilities. Public transit vehicles will make far side stops at both Penny Drive and 40th Avenue NE. Public Transit and Shuttle Buses, Alternative 7 Four to six bays, two to three per side of Sand Point Way NE, will be provided on street as part of the Sand Point Crossing Hub transit and shuttle station. These facilities will be designed to provide a consolidated waiting area for both shuttle and public transit vehicles, enhance passenger safety by consolidating crossings of Sand Point in a single location, facilitate efficient access to campus facilities by providing front-door siting of transit and shuttle facilities and integrating nonmotorized and shuttle support facilities in a single location. Shuttles will layover on campus at the Giraffe entrance and will enter and exit campus via Penny Drive. Adequate space will be programmed for on- or off-site fleet storage and maintenance facilities. Public transit vehicles will make far side stops at 40th Avenue NE, northbound buses east of 40th Avenue NE and southbound buses west of 40th Avenue NE. It is recommended that transit stops at Penny Drive be eliminated to consolidate Children s passenger activity at 40th Avenue NE. Coordination with Metro will occur in design of transit stops. See Figures 32 and 33, Major On- and Off-Site Mobility. Draft Master Plan Alternatives: Transportation and Parking The Draft Master Plan alternatives share many transportation and parking improvements. The traffic generated by 600 pediatric beds at Children s would require 3,600 parking in all but Alternative 1 - No Build. With the enhanced transportation management plan described in Appendix B2, Children s is able to reduce the parking demand by 500 for a total parking requirement of 3,100. Parking for the build alternatives for the hospital campus would be limited to 2,570-2,845 parking ; 255-530 would be located at Hartmann. Hospital Campus All of the Draft Master Plan alternatives, with the exception of Alternative 1 - No Build, would include additional hospital campus-entry access points. These are needed to distribute peak period traffic movements from campus onto streets fronting the hospital campus. This affords improved efficiency and utilization of existing and proposed signals along Sand Point Way NE. Children s, the Seattle Department of Transportation, and the Washington State Department of Transportation are considering additional signals along Sand Point Way NE at 40th Avenue NE and NE 50th Street. Of these, the construction of the 40th Avenue NE signal is planned within the next year. Additional improvements to the existing signal at Penny Drive or adding a new signal at NE 50th Street would be warranted through Children s Major Institution Master Plan. All of the proposed alternatives would require additional access to Sand Point Way NE via NE 50th Street, 40th Avenue NE, and potentially from redevelopment of Laurelon Terrace. These improved intersections along Sand Point Way NE would allow pathways on neighborhood streets to new campus-entry access points proposed in Alternatives 3 and 6 at NE 45th Street and NE 50th Street. In Alternative 7, the NE 45th Street and NE 50th Street campus-entry access points would be eliminated and vehicle pathways would be consolidated on 40th Avenue NE, in proximity to Sand Point Way NE. New signals or improvements to existing intersections would be intended to distribute peak demands from Children s while also enhancing accessibility to Sand Point Way NE from neighborhood streets at NE 50th Street, 40th Avenue NE, and Penny Drive for autos, bicycles and pedestrians. Access The current entrance at Sand Point Way NE and Penny Drive would continue to serve as the main entrance for patients, visitors, physicians, deliveries and service vehicles for Alternatives 3 and 6. In both these alternatives, a new entrance to the campus is envisioned for NE 50th Street. This new access point and the existing access point on NE 45th Street could be used as secondary entrances, especially during peak hours. In Alternative 7 - Expanded Boundary (Early Laurelon Development), two new access points would be added to the existing Penny Drive access on Sand Point Way NE. One entry would be added on Sand Point Way NE between 40th Avenue NE and Penny Drive, approximately at the existing and vacated 41st Avenue NE intersection. Another entry would be added to 40th Avenue NE between Sand Point Way NE and NE 45th Street. The addition of these entries would eliminate the secondary site access points proposed in Alternatives 3 and 6 at NE 45th Street and NE 50th Street, reducing vehicle access through neighborhood streets. All alternatives retain the restricted emergency and service access on NE 45th Street. Alternative 7 would have a limited emergency access on NE 50th Street. Traffic Alternatives 3 and 6 would have two new on-campus driveways to connect the garages along Penny Drive and the surrounding street system via the existing and proposed access points. These new driveways would be on the east side of the proposed North Garage and on the east side of the Whale Garage. Signage and wayfinding would be used to direct traffic during peak and off-peak periods to manage traffic flow on campus and the surrounding street system. In Alternative 7 - Expanded Boundary (Early Laurelon Development), two new access points would be added: a site-access point on 40th Avenue NE and the new Sand Point Way NE 80

Secure bike parking, showers, and lockers for 600 cyclists. Dedicated space for shared bikes program. Clear, direct, and safe connections into and throughout campus for people on foot (including those who arrive by bicycle, shuttle/transit, or private vehicle). Space to serve cyclists, pedestrians, and shuttle and transit riders is consolidated at the 40th Avenue NE entrance. This front door facility welcomes nonmotorized access in a high-quality and attractive location. As Children s facilities expand, the hospital expects to carry more employees and customers to campus on its shuttle vehicles. People arriving on public transit vehicles will disembark on adjacent street curbs and will need safe and efficient access to campus buildings.

< Please Open Page for Additional Text entry between 40 th Avenue NE and Penny Drive, which would include a connection to Penny Drive. This access configuration eliminates the need for the secondary site entrances on NE 45th Street and NE 50th Street as proposed in Alternatives 3 and 6. Pedestrian crossings of Penny Drive would be consolidated to three ADA-accessible crossings between the parking garages and plaza entrances for inpatient, emergency and outpatient services in Alternatives 3 and 6. In Alternative 7, two ADA-accessible crossings are planned between the redevelopment of both sides of Penny Drive. Parking For Alternatives 3 and 6, a new North Garage with between 1,332 and 2,237 parking would be built on the northeast corner of the property. The parking levels in the proposed garage would align with floors of the current Giraffe Garage, which would be connected by an internal ramp and circulation system. Ultimately, the existing Giraffe Garage with its 728 stalls would be included in the new North Garage or redeveloped with buildings and parking. In all build alternatives, the total amount of parking on the hospital campus and Hartmann would be 3,100. Approximately 500 parking could be located on off-site parking lots. Off-campus parking could be used as a means of minimizing neighborhood parking impacts, if necessary. Shuttles, Deliveries and Service The existing Giraffe Entrance would be converted to a loading dock and off-campus shuttle arrival area in Alternatives 3 and 6. In Alternative 7, the existing service and loading areas would be expanded. Also, shuttle arrivals would be increased at an improved Giraffe Entrance plaza. All alternatives would use the existing access driveway from Penny Drive. Transit Public transit will continue to service the hospital campus from Sand Point Way NE and NE 45 th Street. Hartmann It is proposed that the south vehicle access drive be improved and maintained as an unsignalized access point. The north drive would be closed. The south drive would access future underground parking. Four Transportation and Parking Alternatives The Draft Master Plan proposes four alternatives for traffic impact analysis. Each of the alternatives would configure on-site and off-site traffic improvements in concert with Children s Transportation Management Plan (TMP), the Children s shuttle system, provision of parking at the hospital and enhanced traffic dispersal in the regional transportation system. Alternative 1 - No Build Parking Alternative 1 - No Build would require no changes to existing parking counts. Hospital Campus Alternative 1 - No Build would require no modification to internal roadways, building entries and parking. Off-Campus No off-campus public right-of-way improvements would be required. Off-campus parking areas would increase as parking on the campus is demolished for needed site improvements. Hartmann The Hartmann site would not be redeveloped as a part of Alternative 1 - No Build. See Figure 34, Alternative 1 - No Build: Transportation and Parking. Off-Campus Traffic A number of local traffic improvements have been identified, which would facilitate campus access and, in many cases, contribute to improved neighborhood accessibility to Sand Point Way NE. These improvements include, but may not be limited to: Sand Point Way NE/Penny Drive. Realign the Penny Drive intersection with Sand Point Way NE to the north and add left-turn traffic signal phasing to enhance the safety of turns to and from the hospital campus. Sand Point Way NE/NE 50th Street. Signalize the intersection to enhance vehicular and pedestrian accessibility to Sand Point Way NE and the Burke-Gilman Trail while ensuring that the additional proposed garage entrance to NE 50th Street is served by adequate capacity for entering Sand Point Way NE. The specific configuration of these improvements will be subject to further study and ultimately review and approval of the Seattle Department of Transportation (SDOT) and Washington State Department of Transportation (WSDOT). In addition, it is recognized that the required traffic studies to be completed as part of the Master Plan EIS may reveal additional transportation improvements that would reduce or eliminate the effect of added traffic, either from development at Children s or other local traffic growth. SDOT is planning to construct a signalized intersection at Sand Point Way NE and 40 th Avenue NE. 82

Alternative 3 - Proposed Hospital Campus Alternative 3 - Proposed would expand on the improvements planned in Alternative 1 - No Build. Penny Drive would be extended to make a connection at NE 50th Street and NE 45th Street. This would allow traffic on campus at peak periods to be directed to Sand Point Way NE via arterial streets on NE 45th Street and a short residential street on NE 50th Street. A new 1,962-space North Garage would be built on the northeast corner of the property. The parking levels in the proposed garage would align with floors of the current Giraffe Garage, which would be connected by an internal ramp and circulation system. Ultimately, the existing Giraffe Garage with its 728 stalls would be included in the new North Garage. The total amount of parking on the hospital campus would be approximately 3,100. Off-Campus Right-of-Way Improvements Sand Point Way NE/Penny Drive.

Alternative 6 - Modified North Campus Expansion Hospital Campus Alternative 6 - Modified North Campus Expansion would expand on the improvements planned in Alternative 1 - No Build. Penny Drive would be extended to make a connection at NE 50th Street and NE 45th Street. This would allow traffic on campus at peak periods to be directed to Sand Point Way NE via arterial streets on NE 45th Street and a short residential street on NE 50th Street. A new 2,237-space parking garage would be built on the northeast corner of the property, which would increase the overall on-campus parking supply to approximately 3,100 including Hartmann. The parking levels in the proposed garage would align with floors of the current Giraffe Garage, which would be connected by an internal ramp and circulation system. Ultimately, the existing Giraffe Garage would be redeveloped as hospital buildings with below-grade parking. Off-Campus Right-of-Way Improvements Sand Point Way NE/Penny Drive. Realign the Penny Drive intersection with Sand Point Way NE to the north and add left-turn traffic signal phasing to enhance the safety of turns to and from the hospital campus.

Alternative 7 - Expanded Boundary (Early Laurelon Development) Hospital Campus Similar to Alternative 3, Penny Drive is improved. Along its length, the loading dock access is expanded for consolidated service truck movements. In addition, two new ADA crossings would be provided. One would be located at the intersection of Penny Drive and Helen Lane (access drive leading to the Giraffe inpatient entry), and the other crossing would be located between the North Garage and the Pavilion. A new 1,332-space North Garage would be built on the northeast corner of the property. The parking levels in the proposed garage would align with floors of the current Giraffe Garage, which would be connected by an internal ramp and circulation system. Ultimately, the existing Giraffe Garage would be redeveloped for parking and an ancillary hospital use. The overall on-campus parking supply, including Laurelon Terrace and Hartmann, would be approximately 3,100. The potential of a connection between Penny Drive and 40th Avenue NE will be studied for traffic benefits and impact on hospital functions.
