How do I get a soil report in Gunnison County?

Enter your Gunnison County address in the free soil report tool above. It reads the USDA soil survey for your exact parcel — soil series, texture, drainage, slope, and mapped bedrock — and runs the Colorado Reg 43 septic sizing math, instantly and free. It covers every parcel in the county, including land near Gunnison, Crested Butte, Almont.

Who issues septic permits in Gunnison County?

Gunnison County Public Health administers OWTS (septic) permits under Colorado Regulation 43. They require site-specific soil information — usually two logged profile pits — before permitting. The free soil report is the desktop first step; Tri-Lakes Contracting handles the pits, design coordination, and permitting when you are ready.

Is this the same as the soil profile test Gunnison County requires?

No — the free report is a desktop read of the USDA soil survey, ideal before you buy land or start planning. The county permit ultimately requires on-site soil profile pits logged by a qualified professional, which typically run $3,000–$5,000. Tri-Lakes performs both steps and credits the $2,000 feasibility report toward your build.

What does the free Gunnison County soil report include?

Your USDA-mapped soil series and texture, drainage class, restrictive layers and water table, the Reg 43 soil type and long-term acceptance rate (LTAR), septic tank size and soil treatment area for your planned bedroom count, nearby permitted wells, and a foundation recommendation — with a downloadable PDF.

How much does a septic system cost in Colorado in 2026?

For a standard home on a favorable site, budget roughly $18,000–$32,000. For tight soils, steep lots, or advanced/engineered systems common in the mountains, expect $35,000–$65,000. The soil is the biggest variable, which is why a real number comes after the soil test, not over the phone.

Why do mountain septic systems cost more?

Rocky and decomposed-granite soils, shallow bedrock, steep access, and a high frost line all push a mountain lot away from a gravity system toward a pressure-dosed, advanced-treatment, or engineered mound system — and make the excavation harder. That's the difference between a $20,000 system and a $60,000 one.

What's the cheapest septic system I can install?

A conventional gravity system on well-draining soil is the least expensive. But you can't choose it — your soil does. Testing tells you whether your lot qualifies; forcing a cheap system onto the wrong soil is how drainfields fail early.

Does the $2,000 feasibility report count toward the cost?

Yes. The Site Feasibility Report is $2,000 and is credited toward your project if you move forward. It's the first step, not an extra cost — you're pre-paying for work that counts.

How much is a soil / perc test in Colorado?

Soil profile testing runs roughly $3,000–$5,000 — it takes an excavator on site to open two profile pits, read by a licensed evaluator. We quote it after the feasibility visit. In Colorado a soil profile evaluation, not just a percolation rate, is what an engineer designs from.

What your free soil report shows

Your soil, named

The USDA soil series mapped on your parcel — Fourmile, Bresser, Peyton, and hundreds more — with texture (sandy loam, clay loam, decomposed granite) and structure. This is the same starting point a licensed soil evaluator uses.

Drainage & water

Drainage class and wetland indicators. Poorly drained or hydric soil is the single loudest warning a building lot can give — it usually means an engineered or advanced-treatment septic system.

Bedrock & slope

Mapped bedrock depth and slope. Shallow rock within 4 feet pushes a septic design onto an engineered mound; steep grades call for pressure-dosed distribution and heavier excavation.

The Reg 43 septic read

Your soil translated to a Colorado Reg 43 soil type (Type 0 sand → Type 5 clay), the long-term acceptance rate (LTAR), the septic system your land likely needs, sized fields, tank size, and a real installed price range.

Soil report vs. soil testing vs. perc test

These terms get used interchangeably, but in Colorado they are three different things — and knowing which one you need saves real money:

	What it is	Cost	When you need it
Soil report (desktop)	USDA soil survey for your parcel, read for septic under Reg 43. Instant, online.	Free	Before you buy land, early budgeting, deciding if a lot is worth pursuing.
Soil profile testing (on-site)	Two profile pits dug with an excavator, logged by a qualified evaluator. This is what counties accept.	$3,000–$5,000	Required for your OWTS (septic) permit and engineered design.
Perc test (legacy)	The old percolation-rate hole test. Colorado's Reg 43 replaced it with profile pits in most counties.	—	Mostly historical — if a county still asks, we handle it with the profile work.

Start with the free report. If the desktop read looks good, the on-site pits almost always confirm it — and if the USDA maps a problem (clay, shallow rock, high water), you'll know before you spend thousands or close on the land. When you're ready for the county-required testing, we dig and log the profile pits ourselves.

Septic soils: the six types Reg 43 cares about

Types 0–1 — sand & sandy loam

Fast, forgiving soils. Conventional gravity trench systems at the smallest field sizes — the cheapest septic outcome in Colorado. Common in decomposed-granite mountain lots.

Types 2–3 — loams & clay loams

Slower acceptance rates mean bigger drainfields. Still conventional territory, but sizing — and cost — grows with every step down the table.

Types 4–5 — clays

Tight soils that barely accept effluent. Expect advanced treatment (ATU or sand filter) and often an engineered design. This is the answer you want to know before buying.

The wildcards

Shallow bedrock, high groundwater, and steep slopes override everything — they push any soil type toward mounds, pumps, and engineering. Your report flags all three.

Who this is for

Buying rural land? Run the report before you make an offer — a $40,000 septic surprise is the most common budget-killer on mountain lots. Planning a build? The report tells you which septic system to budget and what the county process will look like. Already own the land? Pair the free report with our $2,000 site feasibility report (credited toward your project) for a licensed on-the-ground read of soil, access, well, and septic together.

Colorado soil report — common questions

How do I get a free soil report for my property in Colorado?

Enter your address in the free SepticIQ soil report tool. It pulls the USDA soil survey for your exact parcel — soil series, texture, drainage class, slope, and mapped bedrock — and reads it the way Colorado Regulation 43 does, including the septic system your land likely needs. About ten seconds, no cost.

Is a soil report the same as a perc test?

No. A soil report is a desktop read of the USDA soil survey — free and instant. Colorado counties no longer rely on old-style perc tests; for a septic permit they require on-site soil profile pits logged by a qualified evaluator. The free report tells you what to expect; the pits confirm it.

What does soil testing for septic cost in Colorado?

On-site soil profile testing (two excavator-dug pits, logged for the county) typically runs $3,000–$5,000 on the Front Range. The desktop soil report is free, and our $2,000 site feasibility report — credited toward your project — includes a licensed soil read on the ground.

Do I need a soils report for a septic permit?

Yes. Under Reg 43, Colorado county health departments require soil information — usually logged profile pits — before issuing an OWTS permit. The soil sets your LTAR, which sets the size and type of system you're allowed to build.
