Oceti Sakowin Community Development Vision Plan – Substance Architecture

Oceti Sakowin Community Development Vision Plan

Based in Rapid City, SD, NDN Collective is an Indigenous-led organization committed to building stronger communities and expanding opportunities for Native people in the region and beyond. Through investment, lending, education, and leadership initiatives, the organization supports practical solutions that create jobs, strengthen families, and encourage long-term economic growth.

The Oceti Sakowin Community Development Vision Plan lays the foundation for a vibrant hub in Rapid City where Indigenous families can live, work, and thrive. Designed in partnership with Substance Architecture and a diverse team of experts, the plan will guide the growth of a 66-acre site featuring a new K–12 school, affordable housing, locally focused commercial development, and gathering spaces that foster community pride and resilience.

Central to the plan is the Oceti Sakowin Community Academy (OSCA), Rapid City’s first Indigenous-led school. Built on traditional values and a strong sense of cultural identity, OSCA will provide families with a high-quality education rooted in responsibility, discipline, and land-based learning. The school campus, requiring approximately 40 acres, will serve as both an educational institution and a cornerstone for the next generation of leaders.

Designing Opportunities for All

Many amenities of the campus will also be available for community use, including the Powwow grounds, gymnasiums, indoor gathering spaces, cross-country track, walking trails, and night sky observation space. The buildings will be designed to utilize solar power, earth tubes, and geothermal heat pumps for their energy systems. Rainwater will be captured and reused on-site. Through sensitive site design and construction techniques, the beauty and function of the existing wetland systems and rolling prairie landscape will be preserved and enhanced. By creating a healthy ecosystem, including soil health and native plants, students will have the opportunity to observe the beauty and lessons of natural systems.
