S-09: Auburn Station Access Improvements

Transcription

1 Project Number S-09 Subarea South King Primary Mode Commuter Rail Facility Type Infrastructure Improvements Length Version Number ST Board Workshop Date Last Modified PROJECT AREA AND REPRESENTATIVE ALIGNMENT SHORT PROJECT DESCRIPTION This project would provide additional parking capacity in a new structure at the Auburn Sounder Station. Alternative access improvements to Auburn Station may include, but are not limited to, pedestrian and bicycle improvements, transit speed and reliability improvements on routes connecting to the station, expanded or new kiss-and-ride areas, and expanded parking capacity. This project is part of the ST2 program; however, due to reduced agency revenues experienced during the recent recession, implementation is deferred. Note: The elements included in this representative project will be refined during future phases of project development and are subject to change. REGIONAL LIGHT RAIL SPINE Does this project help complete the light rail spine? CAPITAL COST Cost in Millions of 2014 $ RIDERSHIP 2040 daily boardings KEY ATTRIBUTES No $41 $44 PROJECT ELEMENTS Multi-level parking structure with 600 new parking stalls to be built on the site of the existing surface park-and-ride lot located west of the Sounder Station. The scope of the transit parking components included in this project could be revised to include a range of strategies for providing rider access to the transit facility. Along with, or instead of parking for private vehicles or van pools, a mix of other investments could be accomplished through the budget for this project. These other strategies include the following: o Pedestrian improvements within one-quarter mile of the Auburn Station o Additional bus/transfer facilities at Auburn Station o Bicycle improvements within one-half mile o Transit speed and reliability improvements on routes connecting to the facility o Expanded or new kiss-and-ride areas at Auburn Station o Off-site parking along an existing bus route that frequently connects (20-minute or shorter headway) to Auburn Station during peak periods Closure and demolition of the existing surface park-and-ride lot located west of the existing station platform Signage, lighting, CCTV cameras, and customer emergency stations Page 1 of 6

2 KEY ATTRIBUTES PROJECT ELEMENTS One additional ticket vending machine to accommodate additional users Temporary parking spaces for displaced parking 1 percent for art per Sound Transit policy Sustainability measures (see separate document titled Common Project Elements ) NOT INCLUDED Shuttle bus or other connections between the station and temporary/interim parking stalls See separate document titled Common Project Elements ISSUES & RISKS New agreements, or amendments to existing agreements, with the City of Auburn, BNSF, and King County Metro may be required Agreement with BNSF needed to permit construction Zoning waiver from the City of Auburn will be needed Poor soil conditions and hazardous materials remediation may be required Design and scale of the project could be influenced by expansion of parking at other South Sounder stations Page 2 of 6

3 Sound Transit has developed a conceptual scope of work for this candidate project for the purpose of generating a representative range of costs, both capital and operating; and benefits, including ridership forecasts, TOD potential, multi-modal access and others. This information is being developed to assist the Sound Transit Board as it develops an ST3 system plan, including phasing of investments and financial plan, for voter consideration. Final decisions on project elements (e.g., alignment, profile, number of stations, station locations, and number of parking stalls) will be determined after completion of system planning, project level environmental review, and preliminary engineering during which additional opportunities for public participation will be provided. Therefore, this scope definition should not be construed as a commitment that all representative features will be included in the final developed project. Long Description: Provide additional parking capacity in a new multi-level parking structure at the Auburn Sounder Station with 600 parking stalls to help meet longterm demand. This project will result in a net increase of approximately 500 parking stalls. Alternative access improvements to Auburn Station, may include, but are not limited to, pedestrian and bicycle improvements, transit speed and reliability improvements on routes connecting to the station, expanded or new kiss-and-ride areas, and expanded parking capacity. Assumptions: Temporary parking spaces will be within one-half mile of the proposed structure, likely through lease arrangements Existing Sounder platforms will remain open during the construction period and will be protected during construction The pedestrian bridge connecting the existing parking structure with the station platform will be protected during construction The existing surface park-and-ride lot located west of the existing station platform will be closed and demolished to allow for construction of the new garage Construction phasing to maintain operation of the station, including alternate routing of Metro and ST buses Special traffic control to address a confined site and working near an active railroad Zoning Waiver from the City of Auburn will be needed Environmental: Sound Transit will complete project-level state and federal environmental reviews as necessary; provide mitigation for significant impacts; obtain and meet the conditions of all required permits and approvals; and strive to exceed compliance and continually improve its environmental performance. Utilities: Utility relocation as needed to complete the project, including fiber optics, sewer, water, overhead electric/communications, etc. Right-of-Way and Property Acquisition: Costs associated with obtaining waiver(s) of Auburn zoning requirements related to height of the structure and street-level retail Lease of nearby property during construction for interim parking replacement and possible construction staging and/or storage of materials and equipment Potential Permits/Approvals Needed: Building, electrical, mechanical, utility, land use, and construction-related, BNSF Construction-related permits (clearing and grading, stormwater management, street use, haul routes, use of city right-of-way) Land use approvals (Conditional use, design review, site plans, Comprehensive Plan or development code consistency, Special Use Permits) All required local, state and federal environmental permits NEPA/SEPA and related regulations Project Dependencies: Amendments may be required to the existing three-party station agreement with the City of Auburn, ST, and King County Metro; BNSF to facilitate construction Approval of Zoning Waiver from the City of Auburn Access and demand studies would be required prior to changing this project s scope; determination of what level and mixture of investments would be most effective and affordable within the project's budget would be conducted through a planning effort that includes a more detailed examination of demand and use, as well as coordination with affected jurisdictions and partner agencies, the community surrounding the station/center, and the users of the transit services available at the location; Sound Transit Board action is required to change a project s scope in this manner Page 3 of 6
