Single-Family

OnSite engineers provide comprehensive civil engineering services for single-family residential projects, specializing in infill development and residential subdivisions. Our team partners with homeowners, developers, architects, and builders to deliver practical, cost-effective designs that meet regulatory requirements while supporting sustainable, high-quality communities.

From concept through permitting and construction support, we bring technical expertise, local knowledge, and responsive service to every project.

Stormwater management regulations continue to evolve, with increasing emphasis on runoff rate reduction, water quality treatment, and stormwater detention. Navigating these changing requirements can be complex, particularly as standards vary by jurisdiction and project type.

OnSite engineers excel at interpreting current regulations and applying them efficiently, developing compliant, cost-effective stormwater solutions that meet agency expectations while minimizing construction and long-term maintenance costs. This expertise is integrated into every aspect of our residential stormwater design services.

Stormwater design is a core component of our residential engineering practice. We prepare hydrology studies and stormwater management plans that meet local and state requirements while reducing downstream impacts.
