PORTSMOUTH, Ohio — The city’s Design and Review Board will consider three exterior renovation applications when it meets Friday, including repair work at the Scioto County Heritage Museum’s Marsh House and a new addition to a downtown accounting office.

The board is scheduled to meet at 11 a.m. Oct. 23 in the Engineer’s Office on the second floor of the Portsmouth City Building, 728 2nd St., according to a meeting agenda the board posted to Facebook. Members will also vote to approve minutes from their Sept. 18 meeting before taking up new business.

The five-member Design and Review Board is appointed by Portsmouth City Council to oversee construction, exterior alterations and demolitions within the city’s historic districts. Property owners doing exterior work in those districts must obtain a Certificate of Appropriateness from the board before the city will issue a building permit.

The board’s highest-profile item is an application from the Scioto County Heritage Museum for repairs to the Marsh House at 701 Market St. The project calls for a new soffit and gutters to direct water away from a second-story window, along with brick and mortar repairs to the building’s upper right-hand corner and leveling of a window lintel. A new lintel will also be installed above the front door. According to the application, the work is intended to shore up the building’s front facade and prepare it for further renovation, including the possibility of repainting the entire structure. The Scioto County Heritage Museum is a nonprofit dedicated to collecting and preserving artifacts related to the county’s history.

Homeowners John and Andrea McClellan are seeking approval for a one-story, 18-by-24-foot addition at the rear of their house at 325 Front St. The addition would match the home’s existing 6-in-12 roof pitch and continue its ridge line, with white double-hung windows. The application also covers a full roof tear-off for the house, porch and addition using black architectural shingles, Dutch lap vinyl siding in pewter with gray cedar-shake vinyl on the front gable, black aluminum fascia, gutters and downspouts, and black aluminum railings on the porch and steps.

Tri-State CPA, the accounting firm run by Matt Setters, has applied to add roughly 2,000 square feet to its office at 709 6th St. The addition is designed to match the surrounding streetscape with a brick facade, and the application includes a new front canopy and sign.

The board’s agenda lists no old business before adjournment.
