As part of the Powering Up West: Roanoke to Robison Park (Greater Fort Wayne Reliability) project, American Electric Power (AEP) expanded the existing Sorenson substation. The proposed expansion called for placement of fill in existing wetlands. Therefore, mitigation design and construction was required in order to obtain appropriate regulatory permitting. Williams Creek Management provided regulatory consultation, mitigation design, and construction services to AEP. The mitigation area included approximately 2 acres of forested wetland and 6 acres of existing wetland enhancement. The forested wetland included installation of trees and shrubs to establish a forested habitat. The wetland enhancement included installation of additional native shrub and herbaceous species to the existing site, and invasive species treatment.

AEP also constructed two new 765kV transmission lines between the Sorenson substation and an existing 765 kV line located 7 miles to the south. Right-of-way needed to be cleared, triggering regulatory permitting, mitigation design, and construction. Williams Creek led regulatory coordination for a proposed mitigation design covering 9.5 acres of forested and scrub-shrub wetland. Williams Creek identified the mitigation site and provided mitigation design and construction services.

Another part of the project included a rebuild of the existing 138kV that connects the Sorenson and Robison Park substations as a 138/345kV transmission line. Williams Creek led regulatory coordination for a proposed mitigation design covering 7 acres of forested wetland. Williams Creek identified the mitigation site and provided mitigation design through grading operations, seeding, and planting before providing construction of the mitigation site.
