Parcels, NAIP aerials, and the newest LiDAR that covers your whole site, from the WA DNR portal or USGS 3DEP, plus the constraints a site plan starts with: DNR water-typed streams, NWI wetlands, FEMA flood zones, USDA NRCS soils with hydric ratings, and slope. Clipped to your boundary, projected to WA State Plane, with DXF and DWG included.
Contour Clips was built for small and mid-sized survey, engineering, and environmental consulting firms that don't have a dedicated GIS team.
At a large firm, a GIS department pulls the base data for a new project. At a smaller one, it's our experience that it lands on whoever can spare an afternoon: usually a project engineer, a survey tech, or a staff scientist, and sometimes the principal. The work isn't hard, exactly. It's slow, it's easy to get subtly wrong, and it takes that person away from the survey, the design, or the report.
That's the part we do. We pull the same public data, clip it to your boundary, check it, and deliver it ready for CAD. Your team gets the afternoon back.
Keeping that data current is a job of its own. New LiDAR gets flown, NAIP imagery is updated every two to four years, and parcel and flood maps get revised. We keep up with the sources so your team doesn't have to: each order is built from them when you place it, new LiDAR and imagery years appear on the order page as agencies publish them, and the summary sheet dates every layer.
Contour Clips started inside a Washington environmental consulting practice, pulling this same data for engineering and survey clients.

Bare-earth LiDAR from WA DNR or USGS 3DEP, the newest collection covering your whole site, and contours at any interval from 1 ft.
USDA NAIP aerial imagery (60 cm since 2019), projected to your CRS. Pick older years for change detection.
Existing-ground surface ready to import into Civil 3D.
USFWS National Wetlands Inventory polygons, clipped.
FEMA flood hazard zones (NFHL) clipped to your site, with base flood elevations where mapped. The summary sheet says which FEMA copy you got.
NRCS soils with hydric percentage for early screening.
WA DNR water-typed streams and watercourses.
A slope raster from the LiDAR DEM, in percent or degrees, and a shaded-relief hillshade.
DXF and DWG copies of every vector layer, next to the shapefiles. Included with every order.
Every job runs through an automated QA check before you ever see it.
This is a real package for a 17.6-acre site in Snohomish County, built by the same engine that fills orders. Open it in your own software:
Order parcels, aerial imagery, or a LiDAR DEM on their own ($45 each), or take all three as the Site Basemap bundle ($100, save $35). Add contours to the DEM at any interval from 1 ft ($30 for one interval, +$5 for each extra interval). DXF and DWG are included, sites up to 200 acres carry no area fee, and WA sales tax is added at checkout. Typical site packages run $100–$250.
Get a price →No – and we won't pretend otherwise. A clip is public source data, clipped to your boundary and reprojected: built for basemaps, design backdrops, feasibility, and constraints screening. It isn't a field survey or a stamped boundary determination.
Whatever you specify: EPSG:2926 (North) and 2927 (South), in any NAD83 realization, or UTM. The order page suggests the zone for your site's county. Elevations are NAVD88 in US survey feet, and both datums are printed on the summary sheet.
Yes – DXF and DWG copies of every vector layer come with every order, plus an optional LandXML existing-ground surface, named the way you'd draw them by hand.
Public county, state, and federal services: WA DNR and USGS LiDAR, USFWS, FEMA, NRCS, and NAIP - only sources licensed for redistribution in your deliverables.
The order is held and a person reviews it within one business day. A package missing a paid-for layer never ships – if we can't build it, you're refunded.
