Civil Engineering & Site Plan Services in DC, Maryland & Virginia
Most people know BOZ Engineering Group for structural — but here's what they find out once they start working with us: we do civil engineering in-house too. Site plans, grading and drainage, stormwater management, erosion and sediment control, utility plans, and DC Water design plans — all produced by the same team that handles your structural and geotechnical scope. That means your site plan, your foundation elevations, your soil data, and your stormwater calculations are coordinated from day one — not passed between three firms who never talk to each other. BOZ provides PE-stamped civil engineering for residential and commercial projects across Washington DC, Maryland, and Virginia, with jurisdiction-specific formatting for DC, Fairfax County, Arlington County, Montgomery County, and Prince George's County. One firm, one contract, and every civil discipline your project needs to break ground.
Site Plan Design
Complete civil site plans showing building footprint, setbacks, parking layouts, access points, utility connections, and grading — formatted for the specific jurisdiction where you are submitting. Every site plan is coordinated with your structural and architectural documents so the entire submission package is consistent from page one.
Grading & Drainage Plans
Finished grade elevations, slope design, surface drainage patterns, and stormwater conveyance routing — engineered to move water away from your structure and off your site without causing erosion, ponding, or drainage problems on neighboring properties. We design grading that works with the site, not against it.
Stormwater Management
Stormwater management design including detention, retention, bioretention, infiltration, and water quality treatment systems — sized and engineered to meet the specific stormwater regulations of your jurisdiction in DC, Maryland, Virginia, or Florida. We handle the calculations, the design, and the submittal documentation.
Erosion & Sediment Control
E&S control plans required before any land disturbance permit is issued — silt fence layouts, construction entrance details, sediment traps, stabilization sequencing, and pollution prevention measures designed to keep your site compliant from first grading cut through final stabilization. → Learn More: Erosion & Sediment Control
Utility Plans
Water supply, sanitary sewer, storm drain, and utility connection design from the building to the public right-of-way — including pipe sizing, invert elevations, manhole locations, and connection details. Coordinated with your site plan and grading so utility routes do not conflict with foundations, retaining walls, or other site infrastructure.
Why In-House Civil Engineering Changes the Outcome of Your Project
The number-one reason civil site plans get rejected, delayed, or reworked is coordination failure. The civil engineer designs grading based on assumptions. The structural engineer sets foundation elevations based on different assumptions. The geotechnical report says something neither of them accounted for. The stormwater calculations don't match the grading plan. The utility trenches conflict with the footings. These aren't hypothetical problems — they're the problems we see every week on projects where civil was outsourced to a firm that never spoke to the structural or geotech team.
BOZ Engineering Group eliminates this by producing civil, structural, and geotechnical engineering under one roof. When we design your site plan, we already know your foundation elevations. When we design your grading, we already have your soil data. When we route utilities, we already know where your footings are. This coordination isn't a courtesy review between firms — it's one integrated engineering process where conflicts are resolved on paper, not in the field.
The result is a civil package that passes plan review faster, requires fewer revision cycles, and doesn't generate change orders during construction. For residential site plans, we deliver in 2 to 4 weeks. Commercial projects take 4 to 8 weeks. Large development projects run 6 to 12 weeks. And because most of our clients are already using BOZ for structural, adding civil to the same contract means one point of contact, one timeline, and zero coordination gaps between disciplines.

Civil Engineering Works Best When It Is Coordinated with Structural & Geotechnical & Permitting
Most of our clients bundle structural with MEP and permitting — and the ones who add civil to that same contract get the smoothest projects. Your site plan grading matches your foundation elevations. Your utility trenches don't conflict with your footings. Your stormwater calculations use real soil data from your geotech report. BOZ handles structural, civil, geotechnical, and permitting under one roof — so the disciplines that need to talk to each other actually do.
