Site + Civil Engineering

Make the site work before the details start fighting each other.

Site planning and civil engineering for grading, access, parking, utilities, ADA, drainage, septic coordination, and development infrastructure.

Site development

Geometry, grades, drainage, access, utilities. All connected.

DRJ develops and reviews site solutions with the understanding that every decision moves something else. A curb grade affects drainage. A parking layout affects access. A retaining wall affects grading. A utility conflict can change all of it.

Where DRJ adds value

Small changes matter when the site is tight.

01

Constrained Sites

Work through buffers, slopes, existing grades, setbacks, parking, structures, utilities, and limited disturbance areas.

02

Existing Development

Retrofits, additions, circulation changes, drainage corrections, utility modifications, and redevelopment conditions.

03

Review + Permitting

Plan revisions, agency comments, board review support, coordination, and documentation needed to move approvals forward.

Integrated thinking

Site engineering works better when structural and drainage issues are not treated as somebody else’s problem.

That overlap is one of DRJ’s strengths. Retaining walls, drainage, grading, utilities, and structural elements can be coordinated as one system instead of disconnected disciplines.

One site. One set of constraints.

The solution should reflect how the entire site behaves, not just how one sheet looks.

Have a site that needs to be untangled?
