Multi-Unit Residential Development

Multi-unit residential work succeeds when decisions are made early, plans are grounded in site realities, and the development goals are aligned with the developer's vision and regulatory framework. SESI brings geotechnical, environmental, site civil, GIS, and Natural Resources under one roof to do exactly that. We begin with targeted due diligence and subsurface exploration tailored to the property's specific conditions—historic fill, variable groundwater, utilities, transit lines, and adjacent structures. We then evaluate soil conditions, model settlement, and compare foundation and ground-improvement options, providing clear cost and schedule expectations. Our environmental team structures due diligence and practical remedies that meet regulatory endpoints without unnecessary scope, so financing and land use approvals stay on track. 

The site civil team shapes efficient site layouts for density, access, grading, drainage, and stormwater quality/quantity, using watershed and groundwater modeling where needed. Our GIS/Natural Resources specialists map wetlands, floodplains, and other constraints, translating them into phasing plans that streamline entitlements and construction sequencing. We assemble complete, code-aligned submittals—SWPPP/E&S, subdivision or lot line actions, access improvements, dewatering plans—and coordinate with local boards and state/federal agencies (NJDEP, USACE, EPA). 

Why hire SESI? We turn complex constraints into decision-ready options, communicate effectively, and stay responsive from entitlements, through bidding, and construction. The result is practical engineering that keeps multi-unit projects moving from concept through completion.
