"We're going to take all those concepts and then try to funnel them into one design," Davis said. "The concepts do not stand alone. They are not fixed."

One of the park's most notable features, the berm, was created by dredging along the river and originally considered an eyesore. McGhee said it is one of the highest points along the river and offers a picturesque view.

"Rather than just a lump of grass, we want to make it a feature," she said.

Within a month or so following Wednesday's meeting and public input, the concepts will be taken to a stakeholder group consisting of the city, conservancy and DNR and one model will be chosen, McGhee said. Then, a final master plan will be completed in June.

"It is possible that we will be positioned to allocate design, and possibly development funding, in the 2020 budget, which begins Oct. 1, 2019, for the next phase of Milliken SP & Harbor's construction," McGhee said.

She said work would take place in phases to be determined by stakeholder discussions and level of funding. A final cost or completion date of the project is not known, as those factors are dependent on budget and final blueprints, but McGhee said it would be in the millions. Funding would come in the form of revenue from the state's recreational passports, waterways fund and other grants.

Once finished, officials hope it serves as a unique piece of a bigger plan beginning to progress.

"The conservancy continues to work with key stakeholders, including the City of Detroit and private property owners, towards a strategic plan for revitalizing the west riverfront," according to the conservancy's website.
