Knik Arm Crossing Final EIS Summary Exhibit S-24. Mitigation Measures and Commitments for the Recommended Alternative (continued) EIS section Environmental Conseq uences section title Mitigation Measures and Commitments 4.2.2.6 Pedestrian and bicyclists KABATA will continue to coordinate with the ADOT&PF Central Region, the Mat Su, Anchorage, and AMATS for future pedestrian and bicycle facility improvements and connections. 4.2.3 Impacts on Community Facilities, Public Services, and Fiscal Conditions None 4.2.4 Impacts on Population and Social Groups Adversely affected and appropriately qualified property owners will be assured of fair compensation, as provided by the Federal Uniform Relocation Assistance and Real Property Acquisition Act of 1970, as amended, and the Alaska Relocation Assistance and Real Property Acquisition Practices, Alaska Statutes (AS) 34.60.010 et seq. 4.2.5 Subsistence Impacts See Section 4.8.8.2.2 Essential Fish Habitat (and Anadromous Fish) Marine Fish 4.2.6 4.2.6.1 4.2.6.2 4.2.6.3 4.2.6.4 4.2.6.5 4.2.6.6 Impacts on Utilities 4.2.7 Relocation Impacts 4.3 Joint Development Impacts Joint Development Impacts 4.4 Economic Impacts Relocation of utilities will be conducted in cooperation with Anchorage, the Mat-Su Borough, AWWU, ENSTAR, CEA, MEA, ML&P, major communications service providers, POA, and Elmendorf. Owners of property proposed for acquisition will be eligible for payments provided under the Federal Uniform Relocation Assistance and Real Property Acquisition Act of 1970, as amended, and the Alaska Relocation Assistance and Real Property Acquisition Practices, Alaska Statutes (AS) 34.60.010 et seq. Individuals, families, and businesses displaced by the KAC Project will be eligible for relocation advisory services and payments. Under this law, property owners will be paid the fair market value of real property acquired for rights-of-way (ROW) or easements. Property affected by the KAC Project will be appraised by an independent appraiser to determine fair market value. Owners will be offered compensation accordingly. 4.4.1 Employment None 4.4.2 Economic Sectors None 4.5 Impacts on Physical Environment 4.5.1 Air Quality Impacts 4.5.2 Impacts on Noise Levels 4.5.3 Geology/Soils/Seismic Impacts 4.5.4 Impacts Relating to Hazardous Materials and Contaminated Sites None Construction boundaries will be clearly marked to limit disturbance areas. To control fugitive dust emissions, the construction contractor shall implement BMPs such as watering disturbed soils and reseeding and revegetating as soon as possible after completion of the particular slope or segment. The construction contractor shall adhere to local noise ordinances. If required, a permit will be obtained if Anchorage construction operations occur between the hours of 10 P.M. and 6 A.M. The Mat-Su Borough does not restrict hours of operation for construction projects. Seismic risk will be minimized by adherence to Alaska-specific and national design codes. Detailed geotechnical investigations will continue during the design stage. Avoidance of contaminated sites on Elmendorf is incorporated into the KAC Project design by moving the roadway out onto the beach. Unexploded ordnances (UXO) will present a risk to construction crews. To mitigate this risk and to ensure worker safety, KABATA will retain UXO clearance personnel to clear the construction corridor of UXO prior to intrusive work in the area. A Preliminary Site Investigation (PSI) in the form of a UXO clearance assessment, management plan, and coordination with USACE prior to ROW acquisition or construction will occur. KABATA will complete a UXO construction contingency management plan. The plan will describe procedures for dealing with any UXO encountered during construction activities. Known contaminated sites will be further evaluated during the design phase of the project as Phase II site assessments. Hazardous materials used during project construction will be stored and handled according to state and federal regulations. The contractor will follow Sections 641 (Hazardous Material Control Plan [HMCP] Requirements) and (Spill Prevention, Control and Countermeasure [SPCC] Plan Requirements) in Standard Specifications for Highway Construction (ADOT&PF 2004b). These formal submittals (when approved by the State Engineer) 1) specify the contractor’s detailed responsibilities for preventing pollution stemming from the use, containment, cleanup, and disposal of hazardous material, including petroleum products generated by construction activities and equipment; and 2) detail the contractor’s planned use of oil spill prevention and control measures.

Knik Arm Crossing Final EIS Summary Exhibit S-24. Mitigation Measures and Commitments for the Recommended Alternative (continued) EIS section Environmental Conseq uences section title Mitigation Measures and Commitments 4.5.5 Impacts on Energy Resources None 4.5.6 Ground Water See Section 4.8.1 Water Bodies (lakes, streams, ponds) and Water Quality below. 4.6 Impacts on the Cultural Environment 4.6.1 4.6.2 Impacts on Archaeology and Historic Preservation Impacts on Recreational Resources, Parks, and Wildlife Refuges 4.7 Impacts on Section 4(f) Resources 4.7 Impacts on Section 4(f) Resources A draft Memorandum of Agreement (MOA) to mitigate adverse effects on historic properties, pursuant to Section 106 of the National Historic Preservation Act, has been developed with the State Historic Preservation Office (SHPO) and the Advisory Council on Historic Preservation (ACHP). The draft MOA will be disseminated to all consulting parties with this Final EIS (see Appendix J). Comments received from consulting parties during this review will be considered as the Section 106 process is concluded. FHWA and KABATA are committed to working with the Knik Tribal Council and Native Village of Eklutna to acquire land for a replacement fish camp site in an effort to recognize the importance of Tak’at. Once access has been granted, a qualified archaeologist meeting Secretary of Interior Standards subject to II.B, shall conduct a cultural resource survey of lands within Elmendorf AFB identified as falling under the area of potential effects (APE) for the project. These surveys will be conducted in consultation with the Native Village of Eklutna and the Knik Tribal Council to ensure thorough identification and documentation of any additional potential historic properties within the APE on Elmendorf AFB lands. FHWA has provided alternative measures to the Municipality of Anchorage to mitigate impacts to Sunset and Harvard Parks [refer to 4.7 for details]. A draft Memorandum of Agreement (MOA) to mitigate adverse effects on historic properties, pursuant to Section 106 of the National Historic Preservation Act, has been developed with the State Historic Preservation Office (SHPO) and the Advisory Council on Historic Preservation (ACHP). The draft MOA will be disseminated to all consulting parties with this Final EIS (see Appendix J). Comments received from consulting parties during this review will be considered as the Section 106 process is concluded. FHWA has selected the Erickson Alternative as its Recommended Alternative in part because it has the least-net-harm to park and recreation resources. FHWA has provided to the Municipality of Anchorage all possible planning to minimize harm to the Section 4(f) properties including: • Refinements to the remaining Sunset Park lands after right-of-way is acquired; the disturbed land would be recontoured for park uses. • Cunningham Park Expansion. In addition, subject to consultation with the Municipality during the project’s final design, KABATA will work with the Municipality to investigate the potential of vacating the far northern end of the Cunningham Street right-of-way and adding the vacated land to Cunningham Park, which is currently too small to be of practical use. The vacated portion of Cunningham Street would be a segment approximately 80 feet long between East Cook Avenue and West Bluff Drive. This would add 0.13 acre to the existing Cunningham Park (0.05 acre), for a total of 0.18 acre. Although this is technically smaller than the 1-acre minimum guideline for “mini parks” in Anchorage, it would be large enough for development of a minor park (e.g., overlook bench and small play area) and is much larger than the existing Cunningham Park. • Tunnel “lid” park amenities • Greenbelt trail construction • Payment for the loss of Sunset Park to the Municipality of Anchorage Impacts to three properties determined to be contributing elements of the Government Hill Urban Renewal Historic District would will be mitigated per the requirements of a Memorandum of Agreement between FHWA, SHPO, the Advisory Council on Historic Preservation (ACHP), and KABATA created under procedures of Section 106 of the National Historic Preservation Act (see draft MOA in Appendix E). A draft agreement has been circulated and is the subject of continuing consultation. It is the final Memorandum of Agreement that will govern mitigation efforts. Key elements of the draft MOA, subject to review by Consulting Parties and final agreement by the Signatories, include the following: • Architectural Documentation: KABATA will complete architectural documentation of the affected historic buildings and prepare site plans following Historic American Buildings Survey/Historic American Engineering Record (HABS/HAER) standards. • Historic Preservation Fund. Prior to moving into the final design activities, KABATA will provide funds as seed money to establish an Historic Preservation Fund to be administered by SHPO. This funding would be made available through the Certified Local Government (CLG) Program for the Municipality of Anchorage for historic preservation activities that promote public awareness of Alaska heritage and of the neighborhood characteristics and values that were identified through the Historic Preservation Plan previously initiated and funded by this project in 2006. • Historic Properties Relocation. Prior to those construction actions that could disturb the Government Hill Urban Renewal Historic District, KABATA will investigate the structural integrity and the availability of suitable land to make recommendations on the feasibility of moving any adversely affected historic properties. • Character Defining Features: SHPO has identified the existing system of straight roads and sidewalks as important character defining features (CDFs) of the Government Hill Urban Renewal Historic District and has requested that the project incorporate compatible road and sidewalk design features to minimize the adverse effect on the neighborhood. KABATA will provide “Plans-in-Hand” review design plans incorporating these features to the extent practicable to SHPO for review and comment and will respond to comments received during the review period. • Other: KABATA will construct a cut-and-cover tunnel under Government Hill, and has paid $71,000 through SHPO to the Municipality, and $71,000 through SHPO to the Mat-Su Borough for historic preservation fund planning and development.
