The data presented in this application is intended for use in preliminary, early stage planning processes only. It is not intended to satisfy requirements under Section 106 of the National Historic Preservation Act or other laws and regulations. For project specific analyses, please consult with the appropriate State Historic Preservation Office regarding existing data and additional survey requirements.

Siting-level analyses, while they may employ some of the same data sets as planning-level analyses, will also use other project-specific data sets. Because of the scale at which the regional Transmission Expansion Planning process operates, it is not possible or appropriate to consider all project-level data that could be critical during transmission line siting. WECC recommends any potential transmission corridors generated through this mapping application be thoroughly reviewed against siting-level data and any applicable laws and regulations.

Drawing a few sample lines is recommended to get acquainted with the Corridor Mapping tools.
Click on the map to begin. Each subsequent click will place a new vertex. To complete the line,
simply click on the final point after it is placed. Avoid rapid double-clicking, as this may cause

[Cancel] will remove the line you are currently drawing.
Editing allows you to add and move vertices.
[Save] will commit any changes permanently
[Cancel] will remove vertices added in the editing process, but will not revert the movement of original verteces moved in the editing process
