30 Crossing Environmental Assessment

This Environmental Assessment (EA) for 30 Crossing is being prepared to:

• Evaluate the environmental effects of improving I-30 and I-40.
• Inform and receive feedback from the public and decision makers about the purpose and need for the project, the alternatives that are being considered, and the anticipated environmental effects of the improvements.
• Determine whether effects are significant and require an Environmental Impact Statement or if the project effects can be sufficiently documented through an EA and Finding of No Significant Impacts (FONSI).

Appendix A – Indirect Effects Technical Report
This report presents an analysis of the potential impacts of the project Action Alternatives outside of the proposed project right of way. These potential impacts evaluated include ecological encroachment effects, socio-economic encroachment effects, and induced growth effects.

Appendix B: IJR Traffic Results and Safety Analysis
This document presents the analysis of the operational conditions of the interchanges within the 30 Crossing study area. Based on the analysis of the traffic operations and traffic safety, modifications to existing interchanges are evaluated, and the justification for new interchanges is presented. Conceptual signing plans and a funding plan are presented.

Appendix C: Alternatives Technical Report
This report presents a summary of the evaluation of alternatives that was conducted during the PEL Study, and provides details of the evaluation of alternatives that was conducted during the NEPA study, including the four Action Alternatives that are discussed in the Environmental Assessment.

Appendix D: PEL Public Involvement Summary
This document provides an overview of all public involvement activities that took place while the PEL study was ongoing. This summary includes all public comments on record made during this time.

Appendix E: EA Public Involvement Summary
This document provides an overview of public involvement activities that took place while the NEPA Environmental Assessment study was ongoing. This summary includes public comments on record made during this time.

Appendix F: Community Impacts Technical Report
This report analyzes the potential effects of the Action Alternatives on the communities of North Little Rock and Little Rock. The community impacts analysis performed for the proposed project consisted of analyses of potential impacts to regional and community growth; public facilities and services; access and travel patterns; potential right-of-way (ROW) acquisitions, easements, displacements and relocations; community cohesion; Environmental Justice (EJ) populations; gender, age, and disability populations; and Limited English Proficiency (LEP) populations.

Appendix G-1: Cultural Resources Report
This report summarizes the Phase 1 archaeological investigations.

Appendix G-2: Addendum to Cultural Resources Report
This addendum addresses the archaeological survey in the supplemental project area, extending from the I-40 onramp to John F. Kennedy Boulevard, westward to the I-40 overpass at Pike Avenue.

Appendix G-3: Built Environment Resources Effects Analysis Technical Report
This report provides documentation of the identified historic properties located within the study area, and evaluation of potential effects on these resources.

Appendix H: Section 4(f) Evaluations
This appendix contains the evaluation and documentation of effects on Section 4(f) properties within the study area. It includes a Programmatic Section 4(f) finding on the North Locust Street overpass, and Section 4(f) deminimis findings on North Shore Riverwalk Park, William J. Clinton Presidential Center and Park, and Julius Breckling Riverfront Park.

• North Shore Riverwalk Park
• William J. Clinton Presidential Center and Park, and Julius Breckling Riverfront Park
• Locust Street Overpass

Appendix I: Traffic Noise Technical Report
This report evaluates the potential noise impacts of the Action Alternatives. The analysis presents the existing and future acoustical environment at various receptors located along I-30 and I-40 and recommends measures to mitigate noise effects.

Appendix J: Utility Technical Memorandum
This memorandum describes and assesses the potential impacts to existing utilities and potential need for relocation of utilities within the project study area.

Appendix K: Visual Impacts Technical Report
This report describes and assesses any visual impacts that would be associated with the Action Alternatives, providing information on potential beneficial, neutral and adverse impacts associated with the proposed project.

Appendix L: Hazardous Materials Report
This report summarizes the work performed as part of an initial site assessment and lists potential and historic recognized contamination conditions within the study area.

Appendix M: Streams and Wetlands Report
This report documents the existing wetlands and streams within the 30 Crossing project study area.

Appendix N: Water Quality Technical Memorandum
This document provides governing regulations for water quality, provides background information on the quality of the water bodies in the project area, assesses potential impacts to water bodies from the Action alternatives, and presents potential mitigation options.

Appendix O: Floodplain Technical Memorandum
This report records and evaluates the floodplains in the area. It presents the regulations governing development in floodplains, describes the floodplains found in the 30 Crossing study area, and evaluates potential impacts to the floodplains for each Action Alternative along with proposed options for mitigation.

Appendix P: USFWS Concurrence Letter 4-14-16
This document is a letter from the United States Fish and Wildlife Service (USFWS) documenting 30 Crossing study concurrence with the policies and standards of USFWS.

Appendix Q: MSAT Technical Report
This technical report presents background information on regulations governing mobile source air toxins (MSATs), discusses the scope and methodology of the analysis of the potential effect of the Action Alternatives on MSATs in the project area, and presents the results of the MSAT quantitative analysis for the Action Alternatives.

Appendix R: Cumulative Effects Technical Report
This report assesses the direct and indirect impacts of the proposed Action Alternatives within the larger context of past, present, and future activities that are independent of the proposed project, but which are likely to affect the same resources. Cumulative impacts to community resources, water resources, and historic resources are evaluated.
