Millburn Elementary School

Millburn Elementary School, which also acts as the District 24 administrative facility, was in need of a major expansion to accommodate anticipated growth. As such, the District looked to more than double the size of the building and more than triple its parking capacity, including bus parking for the District-at-large. Such an expansion would impact a large portion of the existing property. In order to provide landscaped athletic and play space, the District worked with an adjacent property owner to rent and improve farm fields with turf fields. The building and parking expansion also precluded an expansion of the school’s septic system, and necessitated a new public sanitary sewer extension connecting to the county system.

Eriksson Engineering Associates, Ltd. (EEA) was retained to provide civil engineering and transportation engineering consulting services for the project. Since the existing school predated the County Watershed Management Ordinance, there was no stormwater management incorporated into the existing site. The new building expansion would also block a major drainage path for offsite flow which was ultimately tributary to an adjacent multi-acre high quality wetland. EEA worked closely with the local regulatory agencies to create a multi-stage substantially natural stormwater management system that met with the current regulations, prevented any flooding of the building or parking while still maintaining the substantial upland wetland flows. Additionally, the building, which had been connected to a septic system required a 1400 LF public sanitary sewer extension designed by EEA.
