J.F. Sato and Associates (JFSA) and a team of consultants joined Forest City Development in an endeavor to redevelop the existing Stapleton Airport site into a mixed-use community with many opportunities for sustainable design. The community will comprise a network of urban villages, employment centers, and significant open space. As one of the main engineering consultants, JFSA worked on a number of projects within Forest City, and was involved in every aspect of the project from start-up through construction to the opening. JFSA's responsibilities on each project have varied slightly, but generally involved civil design for utility infrastructure, utility services, and private and public roadways, bridge design and coordination with public agencies.

As part of the utility design, JFSA prepared drainage analysis, sanitary sewer studies, and water studies to ensure that utilities will support the commercial and residential developments. Drainage analyses and drainage studies used to design the stormwater facilities were produced for multiple projects. As part of the drainage design, JFSA investigated the need for stormwater detention and water quality ponds, and designed facilities as required.

JFSA prepared multiple sanitary sewer studies used to size main lines and service lines for commercial and residential developments. Project sites were divided into basins and average daily flows were calculated based on proposed land use and density as provided by the client. JFSA used flow factors set by the City and County of Denver to determine average flows and infiltration/inflow, and to adequately design sanitary sewer to convey flows generated by the proposed development.

JFSA worked closely with the Denver Water Department (DWD) to provide water demand studies for both commercial and residential developments. Modeling software KY Pipe and EPA Net were used to model pressures, flow rates, and pipe sizes for proposed water systems and the existing system. JFSA also worked with the DWD and Denver Fire to ensure adequate fire hydrant coverage for the proposed project, and that fire flows meet DWD minimum flow requirements.

JFSA worked closely with the City and County of Denver Transportation Department to develop multiple roadway designs within the Stapleton Development. Services included designs for local, collector, and arterial roadways.

In addition to the design services mentioned above, JFSA also provided surveying and stormwater management services within the development.
