Projections indicate that student enrollment at Greencastle Elementary School will exceed capacity by the end of the six-year planning period. As part of the FY2023-2028 CIP, an additional $2.5 million from the county executive's Prevailing Wage and Built to Learn Act PDFs was included in this project to maximize state aid. An FY 2023 appropriation was approved for planning funds. An FY 2024 appropriation was approved for construction funds and an amendment to the FY 2023-2028 CIP was approved for additional funds due to the impact on the construction industry as a result of the Covid-19 pandemic. This addition project is scheduled to be completed August 2025.

MCPS asserts that this project conforms to the requirement of relevant local plans, as required by the Maryland Economic Growth, Resource Protection and Planning Act.
