Putting greens in Boise are published as a custom build rather than a lawn: a tour-grade nylon surface with a published stimp meter rating of 9-11, multiple cups with adjustable pin positions, a longer fringe around the green for chipping, a real sand bunker for practice, and breaks built into the surface as undulation. The published market bands for turf work in this market are 8 to 15 per square foot installed, and 5 to 15 per square foot for a complete professional installation including removal, excavation, a crushed-rock base, turf and infill, with the source publishing line items - 1 to 3 per square foot for removal and hauling, 1 to 3 for excavation and a compacted base, 2 to 4 for basic turf material, 4 to 8 for premium high-face-weight material - rather than a separate green rate. The published base is open-graded #57 or CA7 angular stone compacted in 2-inch lifts to 95% Standard Proctor at a 1% to 2% slope, and a finished surface is published at 15-20 years. Boise Artificial Turf Pros is a free matching service, not a provider: we route your request to licensed local installers, we do not employ contractors, and we do not sell putting green services.

What a putting green installation actually involves
A green is a precision build, and the published specification names its components rather than describing a look. The published surface is tour-grade nylon with a stimp meter rating of 9-11, which is the number that decides how the ball rolls; on top of that, the published features are multiple cups with adjustable pin positions, a fringe of longer turf around the green for chipping, a real sand bunker for practice, and undulation with breaks built into the surface.
| Element | Published description | What it decides |
|---|---|---|
| Surface | Tour-grade nylon, published stimp meter rating 9-11 | Roll speed, and how true a putt holds its line |
| Cups | Multiple cups with adjustable pin positions | Whether the pin can be moved to practise different putts |
| Fringe | Longer turf around the green | Chipping practice off the collar |
| Bunker | A real sand trap | Bunker practice without leaving the yard |
| Undulation | Breaks built into the surface | Slope and break, which are built into the base, not the carpet |
The published consequence of that list is that the shaped part of the job is the base. Undulation and break are built, not laid, so the green is a grading exercise with a surface on it - and the same published base rules that make a lawn last are what hold a green's shape.
The published cost bands and what a green adds
The source material publishes market-wide turf bands rather than a putting-green rate, so a green quote has to be read as the same components with more shape in them. The published bands are:
| Scope | Published band |
|---|---|
| Complete professional installation, per square foot | 5 to 15 |
| Installed artificial turf in this market, per square foot | 8 to 15 |
| Removing an existing lawn and hauling debris, per square foot | 1 to 3 |
| Excavation plus a compacted crushed-rock base, per square foot | 1 to 3 |
| Basic turf material, per square foot | 2 to 4 |
| Premium high-face-weight turf material, per square foot | 4 to 8 |
| Typical 500-square-foot area, whole job | 4,000 - 7,500 |
| Whole-project band published for the market | 15,000 and 35,000 |
Three published points apply to a green. The two published shapes disagree - the per-square-foot rate and the 15,000 to 35,000 whole-project band are not the same job - so ask which applies to your scope rather than blending them. A green uses premium surface material, which puts it at the 4 to 8 end of the material line rather than the 2 to 4 basic end. And the extras that make it a green - cup sleeves, a fringe cut from longer turf, a real sand trap and shaped base work - are published as features of the build rather than as separate published rates, which is exactly the part to have itemised in writing before comparing two quotes.
Why a green is a base project in the Treasure Valley
Undulation is published as breaks built into the surface, and that only happens if the base is graded and compacted to hold it. The published base specification is the same as any turf job in this market, with the tolerance mattering more because a green is a precision surface:
| Specification | Published figure |
|---|---|
| Compaction | 95% Standard Proctor density minimum, in damp 2-inch lifts with a plate compactor; never accept a base below 85% |
| Aggregate | #57 crushed stone, 3/4-inch down to 1/4-inch clean washed angular, or CA7 clear gravel, with 3/8-inch clean chip stone (ASTM #8 or High-Performance Bedding) as the bedding layer |
| Grading | Minimum 1% to 2% slope draining away from buildings, with the break built into the surface deliberately |
| Finished base | Exactly 1.5 inches below the top of the border or edging |
| Tonnage | 1 ton per 100 sq ft at a 3-inch depth; 1.33 tons per 100 sq ft at 4 inches; plus an extra 10% for the 8 to 10% of settling |
The published climate and soil notes matter here too. Boise is a cold-winter, hot-dry-summer valley market, and the case for artificial turf here inverts the desert-water argument used in the Southwest. The NOAA/NCEI 1991-2020 monthly normals for Boise Air Terminal (USW00024131, the station USDA uses for this valley) put January normal average at 32.2 F with a normal daily minimum of 25.5 F and a normal daily maximum of 38.8 F, July normal average at 77.3 F with a normal daily maximum of 92.7 F, annual precipitation at 11.51 inches, and the annual snowfall normal at 17.6 inches (https://www.ncei.noaa.gov/data/normals-monthly/1991-2020/access/USW00024131.csv, HTTP 200). The 2023 USDA Plant Hardiness Zone Map places Boise in zone 7a, i.e. an average annual extreme minimum of 0 to 5 F (map at https://planthardiness.ars.usda.gov/, HTTP 200; ZIP 83702 lookup returns 7a, https://phzmapi.org/83702.json, HTTP 200). Computed from the NOAA ACIS daily record for the same station over 1991-2025 (https://data.rcc-acis.org/StnData, HTTP 200), the median last spring freeze at or below 32 F falls on about May 1, the median first fall freeze on about October 18 - a frost-free window of roughly 170 days - and the station averages about 108 days a year with a minimum at or below 32 F. City of Boise design criteria state Boise's frost depth is 24 inches minimum below grade (https://www.cityofboise.org/departments/planning-and-development-services/building/homeowners-guide/, HTTP 200). Two consequences drive the whole market: for roughly a third of the year the lawn is dormant, muddy and physically unwalkable (a dog-run and back-door problem long before it is a water problem), and the ground itself moves through the freeze-thaw cycle on a scale of a hundred-plus freezing nights. Summer is the opposite - hot, dry and windy enough that keeping a real lawn green is a six-month irrigation project: Veolia's regional president puts service-area demand at 'above 90 million gallons a day' in summer against '25 million gallons during winter' (https://www.cityofboise.org/news/public-works/2026/july/city-of-boise-adopts-drought-ordinance, HTTP 200).
The Treasure Valley floor is not the caliche of the Southwest but it hardpans just as decisively, and at worse depths. USDA-NRCS Soil Data Access samples across the seven towns return loess-and-volcanic-ash-derived Argidurids and Calciargids with silica-lime duripans, plus thick calcic horizons. Purdam, the mapping at the Meridian town centre, is a fine-silty, mixed, superactive, mesic Haploxeralfic Argidurids whose typical pedon carries a strongly cemented duripan from 24 to 38 inches, with depth to duripan ranging 20 to 40 inches and depth to calcium carbonate 12 to 28 inches (https://soilseries.sc.egov.usda.gov/OSD_Docs/P/PURDAM.html, HTTP 200); Purdam's type location is Canyon County about 4 miles southwest of Caldwell. Elijah, mapped across south Boise, is a fine-silty Xeric Argidurids with a continuous, very strongly cemented platy duripan in the typical pedon and a range of 20 to 40 inches to the pan (https://soilseries.sc.egov.usda.gov/OSD_Docs/E/ELIJAH.html, HTTP 200). Colthorp, the mapping at Kuna, is a loamy, shallow Xeric Argidurids with an indurated duripan at 10 to 20 inches and fractured basalt bedrock at 20 to 40 inches - in the typical pedon, duripan 19 to 28 inches and lithic contact at 28 inches (https://soilseries.sc.egov.usda.gov/OSD_Docs/C/COLTHORP.html, HTTP 200); its type location is in Ada County. Against those are the wet, lime-rich soils of Canyon County: Bram, mapped at Caldwell and typed in Canyon County about 2 miles southeast of Caldwell, is a coarse-silty Xeric Haplocalcids that is somewhat poorly drained with a fluctuating water table at 3 to 6 feet for a few months or longer, a calcic horizon from 17 to 32 inches, and subhorizons that are slightly to strongly saline or saline-alkali (https://soilseries.sc.egov.usda.gov/OSD_Docs/B/BRAM.html, HTTP 200). Paulmyers, mapped in north Meridian, is a fine-loamy Aquic Calciargids with a fluctuating water table at 30 to 40 inches from June to August that the series description explicitly says is induced from irrigation (https://soilseries.sc.egov.usda.gov/OSD_Docs/P/PAULMYERS.html, HTTP 200). The Foothills and the southeast benches are the third zone: the Aldape-Dangulch-Castlerock complex on 8 to 35 percent slopes is fine, smectitic and shrink-swell (Aridic Palexerolls, Calcic Argixerolls, Torrertic Argixerolls), and further up-slope the Hullsgulch-Quailridge-Cranegulch complex is fine-loamy to fine, mesic Aridic Argixerolls on 5 to 65 percent slopes (https://soilseries.sc.egov.usda.gov/OSD_Docs/H/HULLSGULCH.html and https://soilseries.sc.egov.usda.gov/OSD_Docs/Q/QUAILRIDGE.html, both HTTP 200). For an artificial turf build that means three things: base excavation and edge restraint can hit a cemented or indurated duripan at 10 to 40 inches, so final depth is whatever the pan allows, not whatever the spec says; in Canyon County the same excavation meets a seasonally high water table and saline-lime subsoil, where drainage, base course selection and what happens to the grade line under freeze-thaw matter more than the topsoil; and on the foothill smectitic clays the native soil shrinks and swells with moisture, so subgrade preparation and edge detail are the failure points. Urban land is the mapped unit over much of built-up Boise and west Boise, so verify the actual lot with USDA-NRCS Web Soil Survey before finalising base depth (https://websoilsurvey.nrcs.usda.gov/app/).
A surface held down tight is the published requirement in these conditions, because a base that moves takes the break with it and a green that has lost its shape cannot be re-tuned without rebuilding the base.
Local note for Kuna
Kuna has the hardest ground in this set: USDA-NRCS Soil Data Access sampling returns Colthorp silt loam, 0 to 2 percent slopes, and Colthorp is a loamy, mixed, superactive, mesic, shallow Xeric Argidurids - a well drained soil whose typical pedon has a Bt horizon at 4 to 8 inches, a calcic horizon from 13 inches, a continuous indurated duripan at 19 to 28 inches, and fractured and jointed basalt bedrock at 28 inches; the series range in depth to duripan is 10 to 20 inches and depth to bedrock 20 to 40 inches (https://soilseries.sc.egov.usda.gov/OSD_Docs/C/COLTHORP.html, HTTP 200). The series was established in Ada County, Idaho, in 1977 and its type location is about 5.5 miles south of the Boise Municipal Airport (same source). This is the strongest single subgrade fact for the market: a base excavation in Kuna can meet an indurated duripan within 10 to 20 inches of the surface and bedrock within 20 to 40 inches, so a standard base-depth specification is not physically achievable on every lot and the pan is a legitimate reason to adjust depth, use a different edge-restraint method, or bring in equipment a shovel crew does not carry.

Checking a quote in Kuna
- How deep will you excavate, and is that depth stated in the contract with the aggregate type?
- Which base material is specified - open-graded washed angular stone, or a dense-graded road base - and where does it come from?
- What compaction target do you build to, and how do you verify it before the turf goes down?
- Where will the drainage slope run on my lot, and how does water and dog urine leave the surface?
- Is the removal of the old lawn, the sprinkler capping and the debris disposal inside the quote or billed separately?
- What infill are you using, how many pounds per square foot, and is the seam and workmanship warranty separate from the turf manufacturer's warranty?
Frequently asked questions
How much does a putting green cost in Boise?
The source material publishes market-wide turf bands rather than a putting-green rate: 8 to 15 per square foot installed, or 5 to 15 per square foot for a complete professional installation including removal, excavation, base, turf and infill. Read as line items, removal and hauling is 1 to 3 per square foot, excavation and a compacted base another 1 to 3, basic turf material 2 to 4, and premium high-face-weight material 4 to 8 - a green sits at the premium end. The published whole-project band for the market is 15,000 and 35,000, which disagrees with the per-square-foot shape, so ask which applies to your scope.
How fast is a backyard putting green?
The published specification is a tour-grade nylon surface with a stimp meter rating of 9-11. Speed is published as a property of the fiber, the infill and the base together, so a target that is not specified up front is not something that can be tuned afterward. Ask for the stimp target in writing, ask how it is checked on the finished surface, and ask how the infill is maintained, because infill is what supports the fiber and the roll.
What does a putting green include?
The published features are a tour-grade nylon surface at a stimp rating of 9-11, multiple cups with adjustable pin positions, a fringe of longer turf around the green for chipping, a real sand bunker for practice, and undulation with breaks built into the surface. The shaped parts - the break, the bunker and the base that holds them - are built before the surface goes down, which is why the drainage and compaction specification is what the finish actually depends on.
