Topex Inc. delivers survey-grade LiDAR data, boundary surveys, civil engineering, and water rights services on the Oregon Coast. Every project is handled directly by Chris Janigo, PE, PLS — so your data is professionally certified, not just collected.
From Lincoln County boundary surveys and engineered drainage plans to water rights and expert witness testimony, Topex covers the full scope of civil and survey work your project needs.
Survey-grade LiDAR mapping with PLS-certified deliverables. Point clouds, DTM/DEM, topographic surveys, infrastructure corridor mapping, construction site monitoring, forestry and vegetation analysis, and earthwork volumes. Sub-foot accuracy, georeferenced to NAVD88/NAD83 — ready for engineering design and regulatory submittals.
Engineered site plans, drainage design, hydraulic modeling, water system analysis, and city engineering support for residential, commercial, and municipal projects throughout Lincoln County.
Boundary surveys, Records of Survey, property line adjustments, construction stakeout, and monumentation. Familiar with Lincoln County land records, the County Surveyor office, and coastal parcel history.
Certified Water Rights Examinations, transfers, due diligence reports, and consulting for coastal and rural Oregon properties. One of a limited number of CWREs practicing in Oregon.
Technical reports, deposition testimony, and litigation support for engineering and surveying disputes. Clear, defensible analysis from a licensed PE and PLS.
CESCL-level design, SWPPP review, and stormwater compliance for grading and construction projects. Critical for coastal Oregon's sensitive drainage environments.
Topex is based in Siletz and has been working in Lincoln County for over a decade. That means familiarity with local parcel history, the quirks of coastal property boundaries, agency contacts, and what it actually takes to get a project permitted and built on the Oregon Coast.
When you hire a local firm, you skip the learning curve. Chris already knows the land records, the common easement issues, the drainage challenges of coastal terrain, and the agencies your project will need to work with.
Also licensed in Washington and Idaho for projects that cross state lines. Based in Siletz means you get a fast response and no travel markup for most Lincoln County locations.
Most clients on the Oregon Coast have to wait weeks for a Portland or Salem firm to schedule a site visit. Topex is already here.
Chris is your point of contact, the person in the field, and the one stamping the plans. No project managers in the middle, no junior surveyors running your boundary.
Active PE, PLS, and CWRE credentials in one person. Very few practitioners hold all three. That combination covers the full range of land and infrastructure projects without referrals.
Lincoln County terrain, tidal boundaries, coastal hazard setbacks, and rural parcel history require local knowledge. That experience is already built into every Topex project.
Call or email and you hear back the same day. No waiting for a receptionist to route your message. Direct access to the expert on your project.
From residential boundary surveys in Siletz to city engineering contracts in Toledo and hydraulic modeling for water districts, Topex has delivered across the full range of coastal Oregon project types. Active licenses in Oregon, Washington, and Idaho mean projects that cross county or state lines don’t require a second firm.

Most drone firms hand you a point cloud and call it done. Topex delivers PLS-certified geospatial data that's legally defensible and ready for engineering, permitting, and construction.
Your LiDAR data is collected, processed, and certified by a licensed Professional Land Surveyor. Most drone firms can't say that. Topex deliverables carry the stamp of a licensed PLS — just like a boundary survey or Record of Survey.
Not just pretty point clouds. Sub-foot accuracy, GCP-controlled flights, and deliverables georeferenced to NAVD88/NAD83. Suitable for engineering design, floodplain analysis, and regulatory submittals — where accuracy actually matters.
We know the terrain, the permitting agencies, and the coastal conditions. Based in Siletz, OR — no mobilization lag, no out-of-area markups. Local expertise backed by professional credentials that out-of-state firms simply don't carry.
