Speed in Numbers
We are speed compounded by certainty. You tell us what you need, and we deliver.

Scope of Service
- Identifying and mapping all environmentally sensitive areas within project boundaries
- Calculating slope extents and setbacks based on municipal definitions
- Preparing ECA-specific topographic maps and delineation drawings
- Coordinating with geotechnical engineers and other consultants for verification and approval
- Producing jurisdiction-ready CAD and PDF deliverables for submission
ECA projects typically involve review by multiple agencies and consultants. Terrane’s coordinated approach ensures data consistency and defensibility through every review and correction cycle.
Our experience spans thousands of ECA-designated sites across the Pacific Northwest. We know each city’s mapping standards, approval cycles, and review processes—allowing us to deliver compliant ECA surveys faster and with fewer corrections.
This is how we deliver faster and with more certainty than anyone else.
When we say that “we run the chain,” what we mean is that every deliverable, every site visit, every stamped survey is part of a closed-loop system that compounds speed and precision, from start to finish.
We call it our superpower, and it’s what makes same-day proposals, 5-day guaranteed delivery, and multi-phase project execution possible.
An integrated network of people, technology, and quality control that keeps 2,000+ jobs running without a slip.
Faster proposals mean earlier alignment.
Locked timelines mean more certainty.
Precision surveys mean fewer revisions.
A single partner means no handoffs, no confusion, no backlogs.
Why It Matters
In land development, delays don’t just cost time. They cost margin, momentum, and trust.
Time Is The Measure
Survey Center
ALTA Survey
A detailed land title survey meeting ALTA/NSPS standards, providing boundary, easement, and improvement data for property transactions and financing.
Boundary + Topographic Survey
Combines property boundary mapping with topographic data to support site design, grading, and permitting.
Short Plat
Subdivides land into a limited number of lots—typically four or fewer—consistent with local short subdivision ordinances.
Construction As-Built Survey
Records the constructed locations and elevations of utilities, structures, and improvements to verify conformance with approved plans.
Telecom Boundary Survey
Maps parcel boundaries, easements, and topography for wireless site development and lease documentation.
"What Survey Do I Need?” A Straight Answer for Builders and Developers
You're trying to keep the job moving, and now you're staring down topo, ALTA, and boundary survey requirements, and no one's giving you a straight answer. This guide breaks down the types of surveys, what they're for, and when they're required, so you can get the right scope the first time and move the process forward.
How Long Does a Land Survey Really Take? (And Why Ours Are Faster)
Survey timelines are often vague and frustrating. We break down real turnaround times based on job type, permitting region, and complexity so you can set expectations, coordinate your subs, and avoid scheduling slowdowns. Includes same-day, 3-day, and 5-day survey insights, plus what delays to watch for.
Permitting Delays: How Bad Survey Data Blows Up Your Schedule
A missing benchmark. A botched boundary. And suddenly a simple site plan turns into a six-week delay. In this case study, we walk through a real permitting stall caused by inaccurate survey work, and how our team fixed it fast. It’s a cautionary tale, and a reminder that timelines live and die on the data you start with.
