PORT OF SEATTLE MEMORANDUM COMMISSION AGENDA Item No. 5h ACTION ITEM Date of Meeting December 11, 2012 DATE: December 3, 2012 TO: Tay Yoshitani, Chief Executive Officer FROM: Mike Ehl, Director, Airport Operations George England, Program Leader, Aviation Project Management SUBJECT: Long-Term Cell Phone Lot Design, C800324 Amount of This Request: $408,000 Source of Funds: Airport Development Fund Est. Total Project Cost: $1,768,000 Est. Jobs Created: N/A Est. State and Local Taxes: $96,000 ACTION REQUESTED: Request Commission authorization for the Chief Executive Officer to proceed with design of the Long-Term Cell Phone Lot project in the amount of $408,000. The total project cost is $1,768,000. SYNOPSIS: The Airport's existing cell phone waiting lot will be displaced by construction of new hardstand facilities at its existing location. T herefore, a new cell phone lot is proposed at a location on the south side of S. 170th St. and east of the Airport expressway (Attachment A). A cell phone lot is needed to provide a service to airline travelers by creating a safe and convenient parking area for vehicles waiting to pick-up passengers rather than using curbside parking or parking on roadway shoulders. The proposed location for the new cell phone lot requires a traffic roundabout to be constructed as part of the project to facilitate ingress and egress from the new lot and to mitigate traffic impacts along S. 170th St., the majority of which is right-of-way of the City of SeaTac. This project was included in the 2013 2017 capital budget and plan of finance. The total project budget is estimated at $1,768,000. This request is for $408,000 for design and associated project management and other soft costs. Design will be performed by Port Engineering staff and supplemented by a traffic engineering consultant to provide any necessary traffic flow analysis. Staff will return to Commission at a later date for construction authorization. COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer December 3, 2012 Page 2 of 7 BACKGROUND: There is a shortage of hardstand space for parking aircraft that remain overnight at the Airport. To increase remain-overnight (RON) space, the vacant United States Postal Service Air Mail Center (AMC) and associated parking lot is being demolished and reconstructed for hardstands. Currently the Airport's cell phone waiting lot uses a portion of the parking lot in front of and adjacent to the AMC and must be replaced. Aviation Operations has determined that a new 150-space replacement cell phone waiting lot should be created at the site of the former Radisson Hotel, located immediately south of S. 170th St. (see Attachment A for the locations of the existing and proposed cell phone lots). The proposed project would demolish the existing asphalt pavement; re-grade, re-pave, and stripe the lot; install new lighting; and revise the stormwater system. Access revisions to S. 170th St. would also be required. A roundabout at the terminus of the ramp from the southbound North Airport Expressway (NAE) to S. 170th St. would be constructed to manage traffic along S. 170th St. Over the past decade, two significant developments led airports to develop cell phone waiting lots: the 9/11 events and the ubiquity of cellular phones. Following 9/11, a shift in air traveler behavior occurred throughout the United States. Primarily due to new checkpoint restrictions, passengers and their parties were no longer inclined to meet in the terminal and utilize short-term parking. With the aid of cellular phones, families can contact their arriving parties as they debark the aircraft and time their trip accordingly. The result is an increased demand for curbside parking and curbside congestion, or at the very least, a location to wait for their arriving party. Without a cell phone lot, meeters and greeters either utilize curbside parking spaces or innovate on the fly, often parking on the shoulders of the North Airport Expressway (NAE) or local streets. The Port acknowledged that freeway off-ramps, shoulders, and medians are not safe or legal areas to park vehicles and decided that a cell phone waiting lot is necssary. According to an Airports Council International 2011 report titled "Airport Parking Strategies in a Constrained Environment," 58 out of the top 75 U.S. airports have cell phone waiting lots. Aviation Operations conducted a sensitivity test of cell phone lot demand to determine the optimal number of stalls for the proposed new facility. The analysis included a 90% occupancy factor for planning purposes and incorporated data from an October 2011 survey of existing cell phone lot activity. The October 2011 survey determined the average lot demand was 143 vehicles per hour with an average dwell time of 18.2 minutes per vehicle. Applying a 37% adjustment factor to the October volumes to approximate summer loads increases the average lot demand to 195 vehicles per hour and the peak demand to 392 stalls per hour. Based on available data, the proposed new facility provides 150 stalls to accommodate a peak demand of 450 stalls per hour, providing the lot with the ability to accommodate a 13% growth in traffic before modification. COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer December 3, 2012 Page 3 of 7 The physical layout and location of the existing lot presents problems to the traveling public. Wayfinding to the lot from the southbound NAE is confusing to some customers. The lot traffic pattern has been modified for one-way flow to minimize conflicts, but signage and enforcement continue to be a challenge. Since the lot was not intended to be a long-term facility and was designed around existing facilities, an awkwardly shaped, inefficient parking area was created. The new lot provides the Port an opportunity to design a purpose-built facility that is scalable for future functionality, efficient, and convenient for customers. The project will be funded via the Airport Development Fund. However, staff is currently in discussions with the City of SeaTac regarding the potential use of parking tax funds for the project's main access revision (the proposed roundabout in the S. 170th Street right-of-way). Per an interlocal agreement (ILA) between the Port and the City signed in February of 2006, 36.9% of parking tax funds collected by the City over the 10-year term of the agreement are committed to a negotiated list of Port priority transportation improvement projects. The ILA provides a mechanism for amending the list of projects eligable for parking tax funds. The proposed improvements to provide safe and efficient access to the cell phone lot and to mitigate impacts to traffic on S. 170th Street are currently not included in the ILA. Staff will also pursue a sales tax exemption for certain work on the traffic roundabout under rules and procedures established by the State. PROJECT JUSTIFICATION: The proposed project is justified based on the following reasons: A cell phone waiting lot is an expected Airport-provided service to travelers; Without a cell phone waiting lot, some pick-up vehicles will wait for extended periods at the terminal curbside or along roadway shoulders resulting in congestion and safety problems; The existing cell phone waiting lot will be eliminated by construction of new facilities; A cost effective site is available on the south side of S. 170th St. for a new cell phone lot; The traffic control roundabout will mitigate increased traffic along S. 170th St. caused by the new cell phone lot. PROJECT SCOPE OF WORK AND SCHEDULE: Scope of Work: The new lot would be located at the site of the former Radisson Hotel parking lot. T he entrance for the new lot would be located on the south side of S. 170th St., and vehicle ingress/egress would be facilitated by a roundabout. T he lot will have the capacity for 150 vehicles. Project work will include: Demolition of existing asphalt pavement Site grading, paving, and striping Installation of lot lighting Installation of stormwater system for the lot COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer December 3, 2012 Page 4 of 7 Construction of a roundabout to manage traffic along S. 170th St. Wireless antennas to support access to Port of Seattle wi-fi services Schedule: Design phase: December 2012 June 2013 Construction phase: July 2013 March 2014 FINANCIAL IMPLICATIONS: Budget/Authorization Summary: Capital Expense Total Project Original Budget $1,452,000 $0 $1,452,000 Budget increase $316,000 $0 $316,000 Revised budget $1,768,000 $0 $1,768,000 Previous Authorizations $0 $0 $0 Current request for authorization $408,000 $0 $408,000 Total Authorizations, including this request $408,000 $0 $408,000 Remaining budget to be authorized $1,360,000 $0 $1,360,000 Total Estimated Project Cost $1,768,000 $0 $1,768,000 Project Cost Breakdown: This Request Total Project Construction $0 $1,148,000 Construction Management $0 $116,000 Design $217,000 $217,000 Project Management $126,000 $126,000 Other Soft Costs $65,000 $65,000 State & Local Taxes (estimated) $0 $96,000 Total $408,000 $1,768,000 Budget Status and Source of Funds: This project, CIP #C800324, was included in the 2013-2017 capital budget and plan of finance as a business plan prospective project with a budget of $1,452,000.

COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer December 3, 2012 Page 5 of 7 Financial Analysis and Summary: CIP Category Renewal / Enhancement Project Type Infrastructure Upgrades Risk adjusted discount rate N/A Key risk factors Delays during the design, permitting, and construction phase could cause the project completion date to extend beyond the closing date of the existing cell phone lot, thus there could be a period when no cell phone lot facility is available to customers. Project cost for analysis $1,768,000 Business Unit (BU) Roadway (costs split between aeronautical and nonaeronautical business units) Effect on business performance No revenue is generated by the existing cell phone lot and no revenue will be generated by the proposed lot. Approximately half of the costs of roadway projects are charged to the airline rate base. IRR/NPV N/A CPE Impact Less than $0.01 in year 2014 Lifecycle Cost and Savings: The project's lifecycle cost includes the initial capital cost plus future on-going operation and maintenance costs estimated to be $24,000 per year (in year 2012 dollars). STRATEGIC OBJECTIVES: This project aligns with the Port's Century Agenda to meet the region's air transportation needs at Sea-Tac Airport for the next 25 years. ENVIRONMENTAL SUSTAINABILITY: This project will provide the opportunity to apply sustainability principles, including: Low impact development stormwater management (infiltration bioswales and rain gardens) Posting of "No Idling" signs for air quality Asphalt recycling Energy efficient site lighting BUSINESS PLAN OBJECTIVES: Approval for project design, and future approval for construction, will contribute to achievement of the Airport's business plan strategy to become one of the top 10 customer service airports by 2015. COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer December 3, 2012 Page 6 of 7 TRIPLE BOTTOM LINE SUMMARY: The project supports economic development by investing in a new long-term cell phone parking lot to serve the public's transportation needs at the Airport. Environmental sustainability principles will be employed where practicable and consistent with Port policy. Also, procedures set forth in the Port's new Small Contractors and Suppliers Program will be used when applicable in the project contracting process in coordination with the Office of Social Responsibility. ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: Alternative 1 Do nothing: Under this alternative the existing cell phone lot will be lost due to installation of hard-stand as part of the RON work at the Airport. A replacement cell phone lot would not be constructed. Pick-up vehicles for travelers would not have a convenient short-term waiting location and increased congestion at the terminal curbside and illegal parking along roadway shoulders is expected. This alternative is not recommended. Alternative 2 Cell phone lot at a different location: Staff investigated other potential sites for a new cell phone lot, including the quick-turnaround area at the Rental Car Facility and along the old northbound North Airport Expressway on-ramp. These locations are less desirable than the proposed location due to more difficult access, higher infrastructure needs, higher costs, and possible conflicts with future Airport facility plans. This alternative is not recommended. Alternative 3 Cell phone lot as proposed: Under this alternative a new cell phone waiting lot would be constructed on the south side of S. 170th St. and a traffic control roundabout would be constructed to facilitate ingress/egress at the lot. This is a cost-effective plan to replace the existing cell phone lot and maintain customer service. This is the recommended alternative.
