The Pine Island Development Assemblage offers a rare opportunity to control over 122 contiguous acres in Plainfield Township, Kent County, one of the fastest-growing suburban corridors in the Grand Rapids MSA. The property includes two complementary tracts: Lake Side (44.86± acres) – improved institutional campus with 70,000± SF of existing structures, extensive frontage on Little Pine Island Lake, and access to public utilities along Pine Island Drive. South Side (77.4± acres) – primarily vacant residential land characterized by mature forest, rolling topography, and approximately 22 acres of protected wetlands ideal for conservation or clustered site planning. Zoned PUD, R-1B, R-1C, and Rural Estate Residential, the assemblage accommodates residential, institutional, hospitality, and mixed-use redevelopment. The site benefits from excellent access via Pine Island Drive, M-44 (East Beltline), and US-131—just 10 minutes north of downtown Grand Rapids and minutes from the Alpine Avenue retail corridor. Regional demographics support upper-middle-income residential absorption: 3-mile median household income of $92,000+, population growth exceeding 1% annually, and limited supply of large entitled tracts in northern Kent County. The property can be sold in whole or divided into the Lake Side and South Side components.
