Improvements to Dublin's Holder-Wright Park are underway, and the facility is expected to be open to the public this fall.

The city has budgeted $1.125 million for the 21.4-acre park, said Matt Earman, Dublin's director of recreation services.

Improvements include a parking lot, restroom and plaza area, a bridge over Wright's Run (Billingsley) Creek and a path to the existing Holder-Wright farm- house.

The park lies between Bright Road and Emerald Parkway a little east of Riverside Drive.

Earman said the improvements will allow the city to hold tours and educational programs in the new park.

Thomas & Marker Construction Co. began working on the park in February. The bridge over the creek, which is about 100 feet in length, is being completed this week, Earman said.

A park-opening event likely will be scheduled in September.

According to the park master plan, the farmhouse dates to the early 1800s. The city-owned 21-acre site is part of a study site consisting of 47.1 acres where prehistoric earthworks and burial mounds dating to 200 B.C. through A.D. 400 have been identified.

Of that site, 26.5 acres are privately owned. Because of the land being used for agricultural purposes, several of the mounds are difficult to see.

Among other improvements listed in the master plan are an outdoor classroom and demonstration garden, eastern and western trail systems, a demonstration mound, perimeter multi-use trails and the restoration of Ferris Cemetery.

The city doesn't have any plans to purchase the private property, Earman said.

And improvements to Ferris Cemetery as well as the addition of western trail systems would hinge on such a purchase, he said.

Throughout the project, Dublin has worked with Ohio State University's archaeology department to ensure any excavations made won't disturb the site's historical components, Earman said.

"It's such a unique preservation of history of this area," he said.

"It's got so much to offer to the public in the way of just knowledge of what happened on our lands before our time."

Jules Angel, from the Ohio State department of anthropology, said she's worked on the site periodically since 2004. She worked with Dublin on the site in 2013, 2014 and this year to make sure planned park infrastructure wouldn't interfere with any archaeological preservation efforts.

The Wright family built their farmhouse on the land before the 1900s and had no idea their property had prehistoric mounds on it, said Dublin Historical Society president Tom Holton.

Excavation of the mounds began in the late 1880s, Holton said.

Anthropoligists have found artificacts and burials.

Holton said he believes the site could be the northern-most mound in the Ohio Hopewell mound complex, which also includes locations in Newark and Circleville.

"This is true, rare history, literally in your backyard," he said.
