Marble Cliff Project

Rendering of Fifth Avenue Substation Upgrades

Since our community open house in March, we’ve finalized plans to upgrade and expand our Fifth Avenue substation in the Village of Marble Cliff. With phase one now complete, this multi-phase project continues in order to meet the growing capacity needs of the area.

In early June, we’ll begin phase two of our work as outlined below, pending any weather-related delays.

Please visit this page for regular project updates and for answers to frequently asked questions.

Week of May 30

  • A temporary fence will be installed around the construction site to ensure safety and will remain throughout the duration of the project.
  • Heavy machinery and equipment will be delivered in preparation for demolition of the vacant building on-site.

Week of June 6 - Mid July

  • The vacant building on-site is set to be demolished early in the week of June 6 using an excavator, pending any weather-related delays. The demolition process will take approximately two days to complete.
  • We’ll send out an automated phone call approximately 24-48 hours before demolition begins. Please make sure your phone number is up-to-date at AEPOhio.com/Account.
  • Continued clean-up of the construction site will last four to six weeks, including the removal of asphalt.

Once phase two is completed, we’ll begin the next phase which includes grading the site to prepare for the installation of new station equipment.

Temporary disruptions of Fifth Avenue at the site will be required to complete necessary work during the construction process. We’ll coordinate with local traffic control to minimize the impact, while working to ensure the safety of the community and our crews.

We’re committed to keeping you informed as we move through each phase of this improvement project and will share more information about what you can expect each step of the way.

Frequently Asked Questions

Project

We’ll be upgrading and expanding our Fifth Avenue substation in Marble Cliff. This also includes connecting our distribution and transmission lines to the expanded station.

This is a multi-phased project that also includes moving Marble Cliff electric service to be powered by the expanded substation to improve reliability during a later phase. We’ll keep you informed as we move through each phase of this project and will share more information about what you can expect as plans are finalized.

The Fifth Avenue Substation is nearly 70 years old. This station project upgrade and expansion is critical to meet the growing capacity needs of the area. Additionally, the project will provide improved reliability in both the residential and commercial areas of Marble Cliff.

Once demolition begins, it will take approximately two days to complete. Work will be completed during the hours of 7 a.m. - 6 p.m. Monday through Saturday to minimize disruption for our customers.

An excavator will be used to complete demolition.

Clean-up and removal of debris will take approximately four to six weeks to complete, wrapping up in mid-July. We’ll also have dust mitigation in place to minimize spread beyond the construction site.

All eligible material will be recycled.

Location

The project will take place in Marble Cliff near the intersection of Riverside Drive and Fifth Avenue in central Franklin County.

This site represents the most suitable location that represents a balance between impacts on the natural and human environments, while meeting the purpose and need of the project. Also, the proximity of the location to the current station will mean minimal relocation of transmission and distribution facilities, as well as minimizing disruption to existing customer electric service.

AEP hired an independent consultant who evaluated nine different through field reconnaissance, research on each site’s setting and vicinity land use and the feasibility of transmission and distribution line connectivity. Of these nine sites, three were advanced for further consideration to determine which would be most viable and appropriate to serve the purpose and need of the project.

The expanded substation will ultimately serve areas including Marble Cliff, Grandview Heights, Upper Arlington and surrounding areas.

Community

AEP Ohio has finalized plans for the Fifth Avenue Substation that incorporates feedback from the community to significantly improve the existing aesthetic views at the intersection for the community. You can view the updated renderings.

We will make every effort to minimize disruptions; however, temporary disruptions of Fifth Avenue at the site will be required during the construction process. We’ll coordinate with local traffic control to minimize the impact, while working to ensure safety for the community and our crews.

We’ve worked to eliminate the need for any power outages as part of this phase of our work.
