An Indianapolis developer is lining up a roughly $47 million apartment project beside Mason’s long-shuttered Beach Waterpark, aiming to turn a sleepy stretch of highway-facing land near Kings Island into a dense pocket of new housing. The plan would convert underused acreage along Beach Boulevard into multifamily units and push new infrastructure into a corridor that has seen only occasional growth for years.
Project details
Indianapolis-based Milhaus is leading the effort and expects to invest about $47 million in the apartments, according to the Cincinnati Business Courier. The outlet reports the team is eyeing a summer 2026 groundbreaking and is planning roadway improvements intended to better connect Beach Boulevard with nearby streets.
Site and history
The site sits immediately west of the former Beach Waterpark at 2590 Waterpark Drive, a 35-acre attraction that has been dormant in recent years. The park’s address and facility information remain listed on its website, and historical references indicate the attraction has not operated in recent seasons. Both the official The Beach Waterpark page and archival summaries point to the property’s long vacancy.
About the developer
Milhaus is a multifamily developer and manager based in Indianapolis with projects spread across the Midwest, according to its website. The company promotes communities that combine market-rate apartments with amenities and neighborhood connections, and its portfolio highlights several regional developments. Milhaus has been stepping up its presence in nearby markets in recent years.
What neighbors and planners may expect
Regional project trackers and property listings indicate the Beach Boulevard corridor has become a target for new housing. One development roundup lists a Milhaus project in the Mason area at roughly 223 units, and public parcel records show active ownership on Beach Boulevard. Reports from MMG Real Estate Advisors and entries on Crexi reflect the scale of what is being discussed for the area. Recent zoning changes in the district, recorded in Mason’s code library, suggest city planners have been laying groundwork for denser development along this stretch of Mason.
