There are many factors BPA evaluates as we consider alternatives for new transmission system facilities, including the new transmission line and substations proposed for the I-5 Corridor Reinforcement Project. Foremost is whether the project can meet the electrical need BPA has identified. Then, BPA evaluates whether each alternative can achieve other project purposes: using ratepayer funds responsibly and efficiently; minimizing impacts to the natural and human environment; maintaining system reliability and performance; and meeting BPA’s statutory and contractual obligations.

Recently, we completed a preliminary count of houses near our four route alternatives and shared that with you. We now have additional preliminary data to share with you. Some examples: preliminary cost estimates for each of the four route alternatives; acres of timber land cleared; number of schools near proposed routes; miles of access road easements acquired; and acres of wetlands filled.

The information in the data table is not listed in order of importance. The accompanying data source and assumption sheet describes how we determined the numbers in the data table. The table does not contain all the information, including public comment, which we will use to evaluate the alternatives for this project.

We may update this information as we learn more from you and as we continue our environmental review.
