| ARCH D (24"×36") sheet | ✓ | ✓ |
Professional 24"×36" architectural sheet with double-line border, title block, vicinity map, north arrow, scale bar, and setback schedule — the same format surveyors and engineers use.
Contour lines generated from USGS National Elevation Dataset with labeled major/minor intervals. See the actual slope, drainage direction, and elevation range of your property.
Every site plan includes a DXF file with proper layering — BOUNDARY, CONTOUR, BUILDING, SETBACK, SEPTIC, WELL, DRIVEWAY. Opens directly in AutoCAD, Civil 3D, or any CAD software.
As you place buildings, wells, and septic systems, setback distances are calculated in real-time. Front, side, and rear setbacks plus the required 100-foot well-to-septic separation.
Place your house, garage, well, septic tank, soil treatment area, ATU, driveway, and parking — all with interactive drag-and-drop on a real parcel map with aerial imagery.
Well permits from Colorado Division of Water Resources, soil data from USDA SSURGO, FEMA flood zones, and wildfire risk — all integrated for Colorado properties.
Most Colorado counties require a site plan as part of the building permit application. Whether you're building in El Paso County, Teller County, Douglas County, Park County, or anywhere else in Colorado, Build Cost Check generates the preliminary site plan you need to get started. Our ARCH D format matches what county building departments expect to see.
Traditional site plan drafting services charge $99–$329 and take 24+ hours because a human drafter traces satellite imagery by hand. Build Cost Check uses real GIS parcel data, USGS elevation models, and USDA soil surveys to generate a more detailed plan, instantly.
Your site plan includes property boundary with dimensions, topographic contour lines from real elevation data, proposed building footprint with measured setbacks, well location with 100-foot septic separation circle, septic tank and soil treatment area with proper sizing, driveway alignment with length and surface type, and a complete title block with project information, setback schedule, site statistics, and general notes.
Before you close on vacant land, know what you're getting into. Our Property Feasibility Report ($49) tells you the well depths in your area, whether the soil supports a septic system, if the property is in a flood zone, the wildfire risk level, terrain slope and drainage, and estimated development costs. Our Soils & Septic Report ($9.99) gives you a deep dive into the USDA soil profiles with foundation recommendations and septic sizing.
