The Turk Island Landfill Sports Complex Conversion project was divided into two phases: site preparation of the proposed landfill, and evaluating the sports complex and open space development on the capped landfill site. This site presents both regional and environmental aspects unique to its proximity due to its shoreline adjacency. The site, composed of over sixty acres, is surrounded by an increasingly more urbanized area with development occurring up to and adjacent it.

The closed landfill represented a unique opportunity to address local and regional needs for recreation. Located on the shoreline of the San Francisco Bay, it contains a control drainage system to the north and a wetlands area adjacent the residential area. An existing small park was located on normal land. The sports complex was proposed on Areas A and B of two landfill parcels which required consolidation and regrading of landfill portions. Callander Associates was selected by the landfill developer for landfill and recreational planning expertise, and collaborated with the team comprised of civil, geotechnical and environmental consultants.
