The developer of the Grandview Crossing mixed-use development has been given the green light to begin planning for the construction of the first elements of the project's Grandview Heights portion.

The planning commission gave its approval Sept. 18 to the proposed site plan, excluding the senior-living building, hotel building and one retail, commercial and residential building east of the hotel.

Wagenbrenner Development is planning the 55-acre project along Dublin Road, with about 15.9 acres in Grandview and the remaining parcels in Columbus.

The Grandview portion is expected to include up to 50,000 square feet of office space, up to 250 senior-living apartment units, up to 50,000 square feet of retail space and the hotel, with up to 200 rooms.

The site-plan details approved by the commission include three 1-story buildings: a 8,888-square-foot building fronting Grandview Avenue and 7,257- and 10,964-square-foot buildings along Dublin Road.

The buildings would include a mix of general retail, restaurant and office uses.

The tenants for the buildings have not been announced.

A pocket park is planned for the Grandview portion of the development, said Todd Foley of Pod Design, a consulting firm working with Wagenbrenner on the project.

The Columbus section of the project is expected to include a small dog park with a synthetic surface, as well as an area that could be used to hold concerts or "as an exceptional place to sit and watch the fireworks on the Fourth of July," project architect Carter Bean said.

The commission also gave architectural approval of the three commercial buildings and a conditional use for a drive-thru window on the east side of the larger building along Dublin Road.

Planning commission member Sarah Kelly said she was pleased with the plans for a bike path along the perimeter of the project area but expressed concern about the narrowness of some areas where cyclists would cross the path of pedestrians.

Cyclists and pedestrians would share a path about 8 feet wide at its narrowest points, Foley said.

The design includes such elements as curves and public art that is intended to help draw cyclists' attention and encourage them to slow down, he said.

"An 8-foot width of a wavy pathway seems narrow for pedestrians and cyclists to share," Kelly said.

If possible, the developer should consider widening the pathway to make it easier for people using their feet and their bikes to coexist along the pathway, she said.

The commission also approved the developer's plans for ground signs but did not act on Wagenbrenner's request that signs for the three buildings be approved.

Details about the size of the wall signs for the buildings won't be known until the tenants who would occupy the buildings are known, building and zoning director Charles Boshane said.
