PREFERRED ALTERNATIVE MAPBOOK

This appendix provides a detailed mapbook of the Preferred Alternative for the 123-mile Project 

corridor, including permanent and temporary limits of disturbance (LOD) from which the 

environmental impacts were evaluated, as described in Chapter 4 of the Final Environmental 

Impact Statement (EIS). The LOD is defined as the boundary within which all construction, 

materials storage, grading, landscaping, and related activities will occur. The permanent LOD 

include all areas where Project infrastructure will physically replace existing conditions and will 

not be restored after completion of construction. Temporary LOD are areas required for 

construction of the Preferred Alternative, such as for construction access or staging and storage 

of equipment, that will temporarily modify the existing conditions, but will be restored after 

completion of construction. In general for the Preferred Alternative, permanent LOD are 0 to 40 

feet outside of the existing CSXT railroad right-of-way, with a maximum offset of 650 feet for 

station improvements. Temporary LOD are generally 10 to 15 feet outside of the permanent LOD, 

with a maximum offset of 50 feet. 

This appendix presents the same elements as the mapbooks from Appendices C through H of the 

Draft EIS for the 23 Build Alternatives, but reflects the LOD of the Preferred Alternative, including 

any changes to the proposed design components between the Draft and Final EIS. The LOD 

changes are the result of design refinements that were made subsequent to publication of the 

Draft EIS in response to public and agency comments on the Draft EIS or from refined data (i.e., 

new data and/or changes to the data that were previously available). 

The Preferred Alternative is based on conceptual engineering, which is approximately a 10 

percent level of design and is appropriate for decisions to be made during the National 

Environmental Policy Act (NEPA) process. The conceptual engineering will be further refined 

during future design phases of the Project (refer to Chapter 7 of the Final EIS for details). 

The mapbook is created at a scale of 1 inch equal to 200 feet when printed at tabloid size (11 by 

17). The basemap aerial imagery for the Project corridor is from the “Most Recent Imagery” 

service provided by the Virginia Geographic Information Network (VGIN) Virginia Base 

Mapping Program (VBMP), dating between 2015 and 2017. 

The following components are included within this mapbook appendix: 

 Permanent Limits of Disturbance (LOD) 

 Temporary (Construction) Limits of Disturbance (LOD) 

 Jurisdictional Boundaries 

 Parcel Boundaries, from County/City Parcel Data
