Module 6

Slide 1 Presentation of the SCEA Analysis & Conclusions

Overview of Environmental Documentation

Slide 2 Overview

SCEA Organization

• Scoping
• Analysis
• Conclusions
• Mitigation

Slide 3 Introduction

Scoping

• Describe the rationale for selecting the resources considered in the SCEA .
  • Provide background information pertinent to the resource (general description of resources within the SCEA study area and their significance and uses)
  • Use maps and overlays to present this information clearly in the environmental documentation.
• Describe the factors and rationale that serving as the basis for establishing the geographical boundary.
• Describe the factors and rationale leading to the selection of the SCEA timeframe.

Slide 4 Introduction (continued)

Analysis

• Describe the data sources used in developing the past, present, and future land use scenarios (Cite data sources).
• Include meeting summaries with local/county planning agencies, MPOs etc..
• Describe the SCEA analysis methodologies (e.g. trends, overlays, matrices and interviews and combinations of these methods).
• Describe effects for each resource considered in the SCEA .

Slide 5 Introduction (continued)

Conclusions

• Describe how the SCEA conclusions were reached.
• Cite applicable regulatory programs and their relationship to the SCEA conclusions.

Mitigation

• Document any proposed mitigation efforts applicable to a resource, such as access controls and agreements with resource agencies.

Additional Support Information

• Include additional support information (Could be included in the appendix) such as:
  • The SCEA resource and methodology matrix
  • Narrative regarding data availability

Slide 6 SCEA Presentation

SCEA DO
Include the results of the SCEA in a separate section of the Environmental Consequences chapter of the environmental document.

Slide 7 SCEA Presentation (continued)

Remember the following when presenting your SCEA :

• Document resource impacts for each build alternative .
• If secondary effects are relevant to the project, then separate secondary and cumulative effects discussions should also appear for each resource within the Effects subsection of the SCEA narrative.
• Exclude data not used in explaining the secondary and/or cumulative effects to a resource.

Slide 8 SCEA Presentation (continued)

SCEA DO
In many cases, your effects analysis may be the same for multiple alternatives because they may be similar in alignment and SHAre the same typical section and access controls. In these cases it is only necessary to present your effects analyses once.

For example consider the following outline:

• A. SCEA of Cultural Resources
  • 1. Historic Properties
    • a. Background
    • b. Trends
    • 1. Alternatives 2, 2A and 2B
      • a. Cumulative Effects Analysis Alternatives 2, 2A and 2B would result in the potential cumulative impacts to 2 NRHP eligible properties.

Slide 9 SCEA Presentation (continued)

SCEA DO

• A. SCEA of Cultural Resources
  • 1. Historic Properties
    • a. Background
    • b. Trends
    • 1. Alternative 2
      • a. Cumulative Effects Analysis Alternative 2 would result in the potential cumulative impacts to 2 NRHP eligible properties.
    • 2. Alternative 2A
      • a. Cumulative Effects Analysis Alternative 2 would result in the potential cumulative impacts to 2 NRHP eligible properties.
    • 3. Alternative 2B
      • a. Cumulative Effects Analysis Alternative 2 would result in the potential cumulative impacts to 2 NRHP eligible properties.

Slide 10 SCEA Presentation (continued)

SCEA DO
Use maps, tables and graphics judiciously in the SCEA writeup to help facilitate agency review.

Slide 11 SCEA Presentation (continued)

At a minimum mapping should be provided for:

• SCEA Geographical Boundary (including support maps such as area of traffic influence, watershed/subwatershed boundaries and census tracts).
• Land use for past, present and future time frames.
• Location of existing resources within the SCEA geographical boundary.
