  • Clarifying the discussion of impacts to Section 4(f) resources and reconsidering determinations on three of those resources.
  • Revising, updating, and clarifying the Indirect and Cumulative Effects (ICE) analysis.
  • Seeking additional public involvement by offering a hybrid style public hearing which offers the opportunity for individual written testimony, individual oral testimony to a court reporter, and/or formal public testimony.

The ROD and FEIS below were completed in 2010, prior to the LS SDEIS.

Notes - In the documents below:

  • Maroon text - Signifies updates addressing changed conditions or analysis, clarifications, or additional information.
