Topex Inc. is based in Siletz, Oregon and serves Lincoln County communities with civil engineering, land surveying, water rights, and expert witness services. You work directly with Chris Janigo, PE, PLS, CWRE on every project.
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.
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.
FAA-certified aerial mapping, survey-grade topographic data, and orthophotos for coastal terrain, rural parcels, and hard-to-access Lincoln County properties.
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 Newport 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.
