PORT OF SEATTLE MEMORANDUM COMMISSION AGENDA Item No. 6d Date of Meeting January 12, 2010 DATE: December 28, 2009 TO: Tay Yoshitani, Chief Executive Officer FROM: Michael Ehl, Director, Airport Operations Wayne Grotheer, Director, Aviation Capital Improvement Program SUBJECT: Request to advertise for construction bids for the 2010 Airfield Improvement Projects Contract 2 at Seattle-Tacoma International Airport (STIA) CIP 100172. REQUEST: Request authority for the Chief Executive Officer to advertise and award a construction contract for the 2010 Airfield Improvement Projects Contract 2, consisting of Third Runway Environmental Mitigation including Miller Creek Relocation Revisions and Restoration, 160th Street Bridge/Culvert Removal; and Third Runway Permanent Stormwater Detention Facility at (STIA). AMOUNT OF REQUEST: $0 SOURCE OF FUNDS: Passenger Facility Charges (PFCs) and existing bond proceeds. SYNOPSIS: This authorization will allow construction bids to be obtained for the scope of work under the overall Third Runway Project. Although the runway is operational, certain projects nearby the runway must be accomplished as required by permits and before the overall project can be completed and closed out. No additional budget is being requested. Sufficient budget for this work within the runway project has already been authorized by the Commission. This project will not increase the Airport's forecasted cost per enplanement. The value of the project is estimated to be $6,625,000. PROJECT DESCRIPTION/SCOPE OF WORK Project Statement: Remove the 160th Street Box Culvert as compensation for the inability of the Miller Creek Relocation Channel to meet a minimum velocity requirement, add gravel to the relocated channel to improve stream flow characteristics and water quality, and complete the conversion of construction stormwater ponds to permanent stormwater detention facilities as required by the permit conditions associated with the Third Runway. COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer December 28, 2009 Page 2 of 5 Project Objectives: Meet the permit conditions required and complete compensatory mitigation associated with the Miller Creek Relocation for the Third Runway. Scope of Work: This authorization is for the advertisement and award of the following scopes of work that are generally indicated on the map labeled Attachment A: Removal of the concrete box culvert and the 160th Street bridge Restoration of the Miller Creek channel in the culvert/bridge removal area Enhancement of the relocated section of Miller Creek with additional gravel and woody vegetation Removal of riprap from the Miller Creek channel Relocation of the existing 160th Street Air Operations Area (AOA) gate to 157th Street and provide for emergency vehicle access into the AOA. Conversion and Modifications of the Construction Stormwater Ponds and stormwater basins SDS6/7 Restoration of sidewalk adjacent to Pond M along 154th Street STRATEGIC OBJECTIVES This request supports the Port's Strategic Objective to Exhibit Environmental Stewardship by meeting required environmental mitigation obligations. ALTERNATIVES CONSIDERED/RECOMMENDED ACTION A. Do not proceed to perform the work. This would violate conditions of the permits that allowed the Third Runway to be constructed. Not performing the work would invite fines, degrade relations with Federal and State agencies and diminish the environmental stewardship activities that the local communities and Port desire. This is not the recommended alternative. B. Proceed to perform the work required by Federal permit conditions. This is the recommended alternative. COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer December 28, 2009 Page 3 of 5 FINANCIAL IMPLICATIONS Budget/Authorization Summary Original Budget $587,362,000 Budget additions $541,594,000 Total Budget 1,128,956,000 Returned Savings -$115,000,000 Revised Budget $1,013,956,000 Previous authorizations $1,128,956,000 Current request for authorization $0 Total authorizations, including this request $1,128,956,000 Remaining budget to be authorized $0 Project Cost Breakdown Construction costs $5,000,000 Sales tax $475,000 Outside professional services $150,000 Aviation Project Management and other soft costs $1,000,000 Total $6,625,000 SOURCE OF FUNDS This project is included in the 2009-14 capital budget and plan of finance within the Third Runway program (CIP C100172). The funding source will be a combination of Passenger Facility Charges (PFCs) and existing bond proceeds. These estimated costs will not cause the total projected costs to exceed the revised budget, and will not affect cost per enplanement (CPE) as these projects were already included in the CPE forecast. ECONOMIC IMPACTS The Third Runway project will have generated an estimated 900 jobs over the life of the construction. The Runway indirectly supports the passenger and cargo airline industry and related businesses in the region. An estimated 30 different jobs of varying crafts with an approximate average duration of 3 months will be employed on-site to complete the construction contract. COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer December 28, 2009 Page 4 of 5 ENVIRONMENTAL SUSTAINABILITY/COMMUNITY BENEFITS As a condition of the permits issued for the Runway project, rigorous environmental standards for the quality of the fill material, construction stormwater treatment and air quality were established. In addition the overall permit includes the restoration of 119 acres of land in the Miller Creek and Des Moines Creek basins to pre-developed conditions and construction of 68 acres of wetland habitat in Auburn. This action allows for the completion of the construction of the mitigation required under the permit. The mitigation sites require 15 years of maintenance and monitoring. Should issues arise adaptive management techniques or solutions will be used to correct future performance issues. TRIPLE BOTTOM LINE SUMMARY This action advances the runway project, which was developed in an environmentally responsible way and overall is a vital regional transportation facility that supports economic growth in many ways.
