The guests on this episode of In-Development are familiar faces! Mariah Samji and Sean Sedgwick join forces to talk about the past, present, and future of IDEA. As Mariah moves on from her role as Executive Director of IDEA, she discusses the legacy and impact the organization has had on the City as well as herself personally. Sean shares what drew him to IDEA and what he hopes the organization can do moving forward. Together, they stew on the challenges, opportunities and future outlook of infill development in Edmonton.

Mariah Samji served as the Executive Director of the Infill Development in Edmonton Association (IDEA) from 2017 to 2024. Driven by a passion for creating inclusive spaces for everyone, she pursued a career in city planning. During her time at IDEA, Mariah worked with the infill community to establish the Builders Education Program, launched IDEA’s annual Infill Symposium, organized numerous events to connect and educate people to make infill easier, started a podcast on redevelopment, contributed to reducing unnecessary infrastructure costs, and collaborated with local experts to implement policy changes that positioned Edmonton as a leader in infill development across Canada.

Sean Sedgwick is the new Executive Director of the Infill Development in Edmonton Association. Sean’s fascination with urban infrastructure and development led him to turn his passion for urbanism from a hobby to a career with the Masters in Urban and Regional Planning program at the University of Alberta. Sean's experience includes a number of years spent working in technology service and support helping to educate and mentor clients and coworkers. He also has a diverse academic background bridging the studies of space and human behaviour, and a personal passion for music and graphic design. He is thrilled to bring these passions to IDEA and put them to use in service of building a better Edmonton.
