A trio of major real-estate development projects – two in Hyattsville and one in Greenbelt – are making their way through Prince George’s County’s development review process. For starters, developers have submitted detailed site plans for approval by Prince George’s County planning authorities for a 350-unit multifamily building near the Greenbelt Metro and the intersection of Cherrywood Lane and Edmonston Road. Route 1 Reporter first wrote about this project back in July, when the developers were seeking approval of their preliminary plan of subdivision, a procedural step where property lines are redrawn or consolidated to accommodate new development. The preliminary plan was approved by planning officials last week. For developer NRP Group LLC, a new face in the D.C. development scene, the project is only its second in region. NRP Group LLC is a large Cleveland-based developer, property management and real estate investment company with a large portfolio.
