The AGGIE-HOMES National Association of Home Builders (NAHB) student competition team submitted a 50-page Rio Chapman Oaks residential sub-division development proposal as part of the 2023 NAHB competition held in Las Vegas, Nevada. The case study involved developing a residential subdivision on a 200-acre property located in La Plata, MD. While there are nine sections of the proposal, the purpose of this poster presentation is to describe the site development plan. Utilizing NAHB topographical maps and the La Plata zoning ordinance, a new site development plan was developed using the AutoCAD software. The site design was also informed by the proposed market analysis and product design. The proposed site design incorporated 100 ft buffers and three culvert crossings to minimize flood risk and ensure resident safety. In compliance with setbacks and market strategy for townhomes and single-family units, three lot sizes were proposed for a total of 844 lots. To incorporate Maryland values and for the relaxation of residents, amenities included four bird watching stations, two pocket parks, and two gazebos with 5% open space. The proposed site development plan meets all critical requirements for La Plata residential subdivision development. AGGIE HOMES presented this proposal to five national NAHB expert judges and placed 18th nationwide.
