Metonic, an Omaha-based real estate developer, held a groundbreaking last week for The Collection at Gretna Landing, a build-to-rent development with 110 freestanding homes at 19817 Ridgemont Street. The project is located within the Gretna Landing development northwest of 192nd & Highway 370. The development will include a mix of two- and three-bedroom cottages, alongside three- and four-bedroom houses with attached garages.
