LAKEWOOD, Ohio -- Both finalists for redesigning the six-acre Lakewood Hospital site envision public spaces, flanked by office, retail and upscale residential space -- possibly 12 or 18 stories tall.

Columbus-based Casto, working with North Pointe Realty Inc., is pitching a 12-story building on the western edge of the property, which would include office and residential floors, with a retail ground floor.

Westlake-based Carnegie Management and Development, which hired former Lakewood Mayor and Cuyahoga County Executive Ed FitzGerald as a consultant, includes two plans, one for a 18-story high-rise building, another for a 6-story building.

Both would revamp the former site of Lakewood Hospital, after years of discord over City Council's decision to close the hospital and open a Cleveland Clinic family health center and 24-hour emergency department in its place.

Check out the details of the plans, which, according to included timelines, would be complete by 2020.

Casto: See the $70 million Casto plan here.

Casto's plan features a 12-story midrise building. The plan also includes a 7,200-square-foot multi-purpose green space, dubbed "The Green," which could hold 900 to 1,200 people for events. "The Grove," an elevated space at the south end of the green, will be shaded and feature a fountain.

Casto is having "productive discussions" with tenants. The online proposal also lists a letter of interest from Mitchell's Ice Cream, though it does not seem to be included in the document.

"Everything is designed to integrate into the existing fabric of the community, adding vibrancy, economic development opportunities, entertainment, and a place for all Lakewood residents," the plan says.

The Carnegie plan keeps the arched Lakewood Hospital entryway as an entrance to a 35,000-square-foot plaza, which would feature a fountain but not green space. The plan also includes a banquet hall and meeting rooms open to the public.

The Carnegie plan, called One Lakewood Center, would include parking hidden for the street -- 940 spots for the high-rise plan, with 150 spaces reserved for the public. For residents, it would include a fitness center, dog walking trail, swimming pool, roof top amenities and exterior recreational areas.

Carnegie lists tenants they're "in talks" with, including a university, grocer, an ice cream shop, several local specialized restaurateurs, a coffee shop, a fitness center, a dry cleaner, a pet shop, an insurance company and a bank institution, but no names are listed.

"For decades, City planners in Lakewood recognized that the lack of a central civic space was a glaring omission in the original plan for the City," the plan states. "This Project finally adds that missing piece to the fabric of Lakewood by creating a sophisticated Plaza that will provide the "town center" experience specifically designed to facilitate culture and community life.

The plans are the most detailed the city has released thus far. A joint public meeting with the Architectural Board of Review and Planning Commission in the auditorium of City Hall at 6:30 p.m. July 25. A proposed plan is expected to come in the fall.
