HyreYard tools

Yard tools, with the reasoning on the page

Twelve working tools for outdoor work most people buy two or three times in a lifetime. Each shows its arithmetic, names its sources, and answers on screen — none asks for an email first. HyreYard does not landscape, lay pavers, cut trees, build walls or fences, sell aggregate or take a referral fee, which is why these can tell you to buy less.

50% of landscape irrigation water described as wasted US Environmental Protection Agency, WaterSense attributes it to "overwatering caused by inefficiencies in irrigation methods and systems" — methods and systems chosen once, at install, by somebody who never sees the bill. Nationally, residential outdoor water use accounts for nearly 8 billion gallons of water each day, mainly for landscape irrigation.

Start with what you are actually doing. Not spent anything yet? The drainage diagnostic and patio size planner cost nothing to act on and routinely change what gets built. Know what you are building? The mulch, gravel and paver calculators turn dimensions into quantities with the arithmetic visible. Holding a bid? The landscaping, fence, retaining wall, tree removal and turf rebate tools take rates off that bid — we ship none of our own. The thing all of them have in common: outdoor work fails below the surface, at the base, the post hole, the grade and the soil, and none of that is what bids compete on.

Everything that goes wrong in a yard goes wrong below the surface

Patios fail at the base. Fences fail at the post hole. Walls fail at the drainage behind them. Plants fail at the soil. In every case the component that decided the outcome is invisible the day the job finishes — which is exactly why bids compete on the part you can see.

Take that seriously for a moment, because it explains almost every complaint people have about outdoor work. Two patios built to completely different base specifications look identical on handover day, and stay identical for about two winters. Two fences with posts at very different depths stand up equally well until the ground freezes a few times. The feedback loop that would let a market reward good work is delayed by years, and by then the crew has moved on and the homeowner has half-forgotten who did it.

Which is why the tools on this page are shaped the way they are. The quantity calculators show the arithmetic rather than hiding it, because the arithmetic is trivial and the assumptions are not. The cost tools ship no rates at all and start every field at zero, because we hold no dataset of yard prices and a default figure is an anchor with nothing behind it. And the diagnostic pages produce questions rather than answers, because a website that diagnoses your drainage from a dropdown is guessing about a lot it has never seen.

What we are. HyreYard does not landscape yards, lay pavers, cut trees, build walls or fences, install irrigation or sell aggregate. We rank nobody, refer nobody, and take no fee from anyone who does any of those things. That is not modesty — it is the reason these pages can end with "buy less of this", "do nothing for a year", or "the honest answer is a smaller patio", which are conclusions the rest of this industry is structurally unable to reach.

Where to start, depending on what you are doing. If you have not spent anything yet, start with the two pages below that cost nothing to act on — the drainage diagnostic and the patio size planner. If you know what you are building, the quantity calculators turn dimensions into cubic yards and pieces. If you are holding a bid, the cost tools take the rate off that bid and show you what the total is made of.

And five things you can look up free, today. Your parcel’s soil on Web Soil Survey. Your hardiness zone on the map USDA Agricultural Research Service revised in 15 November 2023. Your local frost depth from the building department. Your zoning height limit and setbacks. And your own water tariff, off your own bill. Every one of those changes how you should read a quote, and not one of them costs anything or requires a professional.

Before you spend anything

Two pages that cost nothing to act on and routinely change what gets built. Both produce questions rather than verdicts, because the answers depend on ground we cannot see.

How much to buy

Geometry, shown on the page. These are the tools where the arithmetic is simple and the assumptions inside it are where people go wrong — so the assumptions are printed rather than buried.

Rates you type, never rates we ship

Every field on every one of these starts at zero. We publish no yard prices and hold no dataset of them, so none of these can tell you whether your number is high — only what the total is made of and what is missing from it.

The tools, and what each one will not do

The last column is the honest half. Every tool here has a boundary, and knowing it is what keeps the output useful.

ToolWhat it doesWhat it will not do
Mulch calculatorTurns area and depth into cubic yards, with waste shown separately.Let you specify a depth the published guidance calls harmful without saying so. Penn State Extension puts the limit at 2 to 4 inches, less for fine material.
Gravel calculatorThe same geometry, with a compaction allowance you can see and change.Pretend the compaction factor is a measurement. It is editorial, and there is no published national figure for crushed stone.
Paver calculatorSurface area with waste, plus base volume at a depth you choose.Specify your base. Depth follows load, soil and climate, and the published minimums assume well-drained ground.
Patio size plannerTurns a number of seats into a planning area using an allowance we label editorial.Lay out a shape. The same area as a strip and as a square are two different patios, and area does not contain proportion.
Retaining wall calculatorFace area against a rate from a bid.Tell you whether your wall needs engineering. Height, surcharge and soil decide that, and the exemption is measured from the bottom of the footing.
Fence cost calculatorLength times a rate, with gates and removal itemised.Tell you how tall you may build or where your boundary is. Those are zoning and survey questions and a permit exemption answers neither.
Tree removal costDiameter against a quoted rate, plus access and disposal.Assess a tree or a hazard. Tree work is governed by consensus standards — ANSI A300 — the industry consensus standards for tree care operations and ANSI Z133 — the safety requirements for arboricultural operations, applying to employers and employees engaged in tree work — and no website substitutes for an arborist on site.
Drainage diagnosticStructures what you have observed into questions worth asking.Diagnose your lot or specify a drain. Where water goes is a grading question first, and the destination has to be real.
Landscaping cost estimatorAdds four lumps you type plus a contingency you hold.Model the running cost, which is the larger number. Doing that honestly needs your tariff, climate, planting and soil.
Turf rebateYour utility’s published rate times your area, capped by the programme.Tell you what your programme pays. Programmes open, close, change rate and change rules, and a stale national table would be actively misleading.

Our own description of each tool’s boundary. None of these pages holds a price dataset, and none of them ranks, refers or recommends a contractor.

The published figures that decide whether hardscape survives

Four numbers from one document, and they explain most of the difference between two bids that look the same.

Load drives depth. The same surface material sits on half again as much base under a car as under a chair.Interlocking Concrete Pavement Institute, ICPI Tech Spec 2 — Construction of Interlocking Concrete Pavements. Retrieved 2026-09-05.

Base thickness by load

ICPI Tech Spec 2 — Construction of Interlocking Concrete Pavements, © 1995 ICPI, revised February 2020, publishes minimums of 4 inches for a pedestrian patio and 6 inches for a residential driveway, both on well-drained soils, with 8 to 10 inches for residential streets.

And the adjustment. "In colder climates, continually wet or weak soils will require that bases be at least 2 to 4 in. (50 to 100 mm) thicker." So an extra 2 to 4 inches where the ground is wet or weak and the climate is cold.

Read what drives it: the load and the ground, never the paver. Which is why "we could drive on it" is a specification change and not a favour, and why a national base depth quoted without soil and climate attached is not usable information.

Compaction, in lifts

The subgrade target is 98 per cent of standard Proctor density, ASTM D698. That is a density measured against a laboratory reference, not a number of passes with a plate.

And it is achieved in lifts of 4 to 6 inches, compacted with 7,000 lbf (31 kN) reversible plate compactors. A base tipped in one deep layer and rolled on top is dense where you can see and loose where it matters.

Vehicular areas use a different reference again — modified Proctor density, ASTM D1557 or AASHTO T180 — which is another reason a driveway is not a patio with extra stone.

Bedding, and the sentence worth memorising

"Bedding sand should be spread and screeded to an uncompacted nominal 1 in. (25 mm) thickness." A nominal 1 inch, uncompacted, of ASTM C33 or CSA A23.1 FA1 concrete sand.

And then: "If there is an uneven base, the bedding sand should not be used to compensate for it. Over time, unevenness in the bedding sand will reflect through to the surface."

That is the single most useful line in the document for somebody watching a job. If the base is uneven and somebody is making it up with sand, the unevenness has not been fixed. It has been buried, and it comes back through the surface as the thick spots consolidate more than the thin ones.

Materials explicitly excluded: "Masonry sand for mortar should never be used for bedding, nor should limestone screenings or stone dust." All three are common substitutions and all three are cheaper.

The edge, and the slope

"A minimum of 1 in. (25 mm) vertical restraining surface should be in contact with the side of the paver to adequately restrain it." Interlocking pavement works because units share load with their neighbours. That only holds while the perimeter cannot move, which is why failure propagates inward from a lost edge.

"Slopes should be a minimum of 1.5%." Roughly two inches of fall across twelve feet, which is HyreYard arithmetic on the published percentage and is a great deal more than most people picture.

Half the water put on landscapes is described as wasted

Landscape water waste is the largest recurring number attached to a yard, and the published attribution is not to careless homeowners. It is to the system that was installed.

Share of landscape irrigation water described as wastedAttributed in the source to methods and systems rather than to behaviour, which puts the cause at design and install time.
A national statement about landscape irrigation generally. It is not a measurement of any particular garden, and certainly not of yours.US Environmental Protection Agency, WaterSense. Retrieved 2026-09-05.

US Environmental Protection Agency, WaterSense states that residential outdoor water use accounts for "nearly 8 billion gallons of water each day, mainly for landscape irrigation" nationally — about 8 billion gallons a day.

And: "as much as 50 percent of this water is wasted due to overwatering caused by inefficiencies in irrigation methods and systems"

The attribution matters more than the percentage. The waste is put down to overwatering caused by inefficiencies in irrigation methods and systems. Methods and systems are chosen once, at install, by a designer and an installer, and then are expensive to change. That places the decision at exactly the moment when nobody is thinking about a bill that arrives every month for fifteen years.

For scale. The average American household uses more water outdoors than it uses for showering and washing clothes combined.

What the agency says a labelled controller saves. About 15,000 gallons a year for an average home, with national adoption estimated to save around 390 billion gallons and $4.5 billion annually. Those are published national figures for an average household, not a prediction about yours — and whether an upgrade pays back for you depends on your own tariff, which is on your own bill and takes a minute to find.

Which is why the turf rebate page exists in the form it does. Replacing irrigated lawn is the largest single lever available on outdoor water, and many utilities pay toward it. What we will not do is publish a table of who pays what: programmes open, close, exhaust their budgets and change their rules, and a stale national table would send people to programmes that no longer exist. Your utility’s own current page is the only reliable source, and the tool takes the rate you find there.

Two free national lookups that change what you should buy

Both take about five minutes, both are published by federal agencies, and between them they inform the hardscape line, the planting line and the drainage line at once.

Station count behind the two hardiness map editions0Weather stations, 1991 to 2020 edition13,412Weather stations, previous edition7,983USDA Agricultural Research Service. The change in station count is part of the agency’s ownreason for cautioning against reading the zone shifts as a climate indicator.
Published station counts for the two editions. The method changed at the same time as the data, which is precisely the publisher’s point.USDA Agricultural Research Service. Retrieved 2026-09-05.

The soil. Web Soil Survey, USDA Natural Resources Conservation Service. A parcel-level lookup of the mapped soil, its drainage class, its hydrologic soil group and its shrink-swell potential. It is free, it takes about five minutes, and it is the cheapest useful thing a homeowner can do before buying hardscape. It is a survey map, not a site investigation of your lot.

What the runoff classes mean. "A" is low runoff: Deep sands and gravelly sands. Water goes down. "B" is moderately low: Moderately well to well drained, moderate texture. "C" is moderately high: A layer that impedes downward movement, or finer texture. "D" is high runoff: Clays with high shrink-swell, a high water table, a claypan, or shallow soil over near-impervious material.

Why that reaches the hardscape budget. US Environmental Protection Agency describes the mechanism: "much of the land surface is covered by buildings, pavement and compacted landscapes. These surfaces do not allow rain and snow melt to soak into the ground which greatly increases the volume and velocity of stormwater runoff" The EPA page states the mechanism and does not publish a runoff percentage. We do not publish one either. Every patio, path and drive is new impervious area, and on a high-runoff soil the water it sheds has nowhere to infiltrate. Meanwhile the published base guidance calls for a thicker base on wet or weak soils in cold climates — more excavation, more aggregate, more spoil to remove. One free lookup, three budget lines.

The zone. USDA Agricultural Research Service released a revised Plant Hardiness Zone Map on 15 November 2023, built from 13,412 weather stations over 1991 to 2020, against 7,983 previously. "About half of the country shifted to the next warmer half zone, and the other half of the country remained in the same half zone."

With the publisher’s own caveat, which is usually stripped off when this is quoted. "The developers cautioned against treating the changes as a reliable indicator of global climate change, because they also reflect more sophisticated mapping methods, many more weather stations, and the inherently variable nature of extreme minimum temperatures."

And what the map does not do. The map plots the average annual extreme minimum winter temperature — a single cold night in an average year. It says nothing about summer heat, humidity, rainfall, soil, or how long your winter lasts. A plant can be hardy to your zone and still die in your garden because of August heat or a soil that stays wet. Hardiness is a necessary condition, not a sufficient one, and treating it as sufficient turns a planting budget into a replacement budget.

Most yard work needs no permit, and that answers less than people think

Three exemptions get quoted constantly. The sentence printed immediately after them almost never does.

Fences: "Fences, other than swimming pool barriers, not over 7 feet (2134 mm) high."

Retaining walls: "Retaining walls that are not over 4 feet (1219 mm) in height measured from the bottom of the footing to the top of the wall, unless supporting a surcharge or impounding Class I, II or IIIA liquids." Notice that the retaining wall figure is measured from the BOTTOM OF THE FOOTING, not from the ground you are standing on. A wall that shows three and a half feet of face can easily be over four feet by the code’s own measurement, and the person who built it to the visible height has measured the wrong thing.

Flatwork: "Sidewalks and driveways not more than 30 inches (762 mm) above adjacent grade, and not over any basement or story below and are not part of an accessible route."

And then the closing sentence. "Exemptions from permit requirements of this code shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this code or any other laws or ordinances of this jurisdiction."

This is the sentence people skip and it is the whole point. Not needing a permit is not permission to build it wrong, and it is not permission at all under zoning, a deed restriction, a homeowners association covenant, or an easement. Those are separate instruments with separate consequences, and none of them is waived by a building-permit exemption.

How we read this, honestly. That list was read on 5 September 2026 as reproduced in a state-adopted building code — Texas Windstorm Insurance Association Building Code, 2024, section 105.2 — through a code-hosting service. We did not open ICC’s own library. The shape of the model list is stable; the numbers in your jurisdiction are the ones that bind you, and adopting jurisdictions amend precisely these thresholds.

The same is true of anything set in the ground. The frost line itself is not in the model code. It is set locally in Table R301.2 by the adopting jurisdiction, and it is the number your building department publishes for your county. It ranges from nothing in the warm south to several feet in the north, and it is the single figure that decides how deep a post or a footing has to go. We publish the model minimum and the frost provision as we retrieved them and we do not publish a frost depth for anywhere, because that number belongs to your building department and is a free phone call away.

The questions that separate two outdoor bids

The questions below apply across almost every job on this site. All of them concern things that are invisible once the work is finished.

  • What is the base or footing specification, in inches?

    Depth, and what it assumes about the soil. For hardscape the published minimum is 4 inches for a pedestrian patio on well-drained ground, with more for cold, wet or weak conditions. For anything set in the ground, the answer should reference your local frost depth.

  • How will it be compacted, and in what layers?

    A density target rather than a number of passes, and lifts of 4 to 6 inches. This single question reliably separates a crew that knows the published guidance from one that does not.

  • Where does the water go, before and after?

    Walk it with them, ideally in the rain. New hard surface sheds water that used to soak in, and the receiving ground is a real place with a real owner. Slope alone is half a drainage design.

  • What is itemised separately, and what is folded into a rate?

    Access, spoil disposal, edge restraint, gates, removal of what is there now. These are the items that get absorbed into a per-unit rate and then reappear as variations.

  • Who calls for the underground utility locate?

    Somebody must, before anything is dug. It is free to arrange, it is a safety question before a cost one, and it should be named in the document.

  • Do the five free lookups before you read a single bid

    Soil, hardiness zone, frost depth, zoning limits, water tariff. None costs anything, all take minutes, and together they change how you read every number you are about to be given.

The words that recur across these tools

Subgrade
The existing soil everything stands on after excavation. Its compaction is specified — 98 per cent of standard Proctor density, ASTM D698 — because everything above inherits how it behaves.
Base
The compacted aggregate layer that carries the load. Its depth follows the load, the soil and the climate, never the material on top of it.
Bedding
A nominal 1 inch of specified concrete sand. A setting layer, not a levelling layer — the published guidance is explicit that unevenness in it reflects through to the surface.
Edge restraint
The perimeter element that keeps interlock working. Needs at least 1 inch of vertical surface bearing on the paver.
Lift
One layer of base placed and compacted before the next goes on, published at 4 to 6 inches. The concept exists because compaction energy does not reach far down.
Frost line
The frost line itself is not in the model code. It is set locally in Table R301.2 by the adopting jurisdiction, and it is the number your building department publishes for your county. It ranges from nothing in the warm south to several feet in the north, and it is the single figure that decides how deep a post or a footing has to go.
Hydrologic soil group
Four classes describing how readily water enters soil, A through D, published free per parcel on Web Soil Survey.
Impervious surface
Ground that sheds rain rather than absorbing it. Patios, paths and drives all add some, and many jurisdictions cap the total on a lot.
Compaction allowance
Compaction is a real volume change and ICPI requires the base to reach 98% of standard Proctor density. The ratio between the loose volume you buy and the compacted volume you end up with depends on gradation, moisture and the compactor, and there is no published national figure for "crushed stone". Twenty percent is our planning allowance, not a measurement of your quarry.
Permit exemption
A provision saying a building permit is not required for defined work. It removes one administrative requirement from one code and grants nothing under zoning, covenants or easements — the model list says so in its own closing sentence.
DBH
Diameter at breast height, the standard way a tree is measured for pricing and for arboricultural work. Circumference and diameter are frequently confused, and the error is a factor of about three.
Spoil
Excavated material that has to leave the site. It is a haulage and disposal cost that scales with excavation depth, which is why a thicker base costs more than the extra aggregate alone.

What none of these tools can do

Stated once, here, so every page does not have to repeat it — though each of them does anyway, in its own terms.

None of them holds a price dataset. Not for mulch, gravel, pavers, walls, fences, trees, irrigation or labour, in your area or anywhere. Every cost field starts at zero and stays there until you type a number off a bid. That is a deliberate constraint and it means these tools cannot tell you whether a quote is fair.

None of them can see your ground. Soil, grade, access, what is buried, how water currently moves. Those decide most outcomes and they are knowable only by standing there — though the free soil lookup above will tell you which questions to ask.

None of them is a specification. The published figures we quote are minimums for stated conditions from named documents. An engineer or an experienced installer looking at your actual site may reasonably require more, and where a structure, a wall or a slope is involved, that is engineering rather than a calculator.

The code material is model-code material. That state adoption carries an exception for freestanding accessory structures at or below 721 square feet, and a further exception for decks not supported by a dwelling. Both the threshold and the wording are that state’s own — other adoptions we saw referenced in the same search used different areas and different construction types. Treat the existence of an exception as normal and its numbers as strictly local. Adoption and amendment are local.

And some sources we could not read, which we say rather than paraphrase. tcia.org returned 403 to automated retrieval on 5 September 2026. The titles, scope and secretariat are recorded as consistently published by TCIA; no clause text is quoted here, because we did not read the standards themselves.

ICPI has since merged into the Concrete Masonry & Hardscapes Association and icpi.org redirects to masonryandhardscapes.org, so the member mirror is the copy we were able to retrieve on 5 September 2026.

We rank, refer and recommend nobody. No contractor is listed, rated or endorsed anywhere on this site, and we take no fee from anyone who does that. Licence and insurance are free to verify with your state and with the carrier, and in many states irrigation and tree work are separately licensed.

The conclusions these tools are allowed to reach

Almost every source of outdoor project guidance earns when more gets built. This one does not, which is the only reason this section can exist.

Buy less mulch. Past a published depth it starves roots of oxygen — "air may not penetrate the mulch layer and the underlying soil becomes depleted of oxygen" — and the correct instruction is often to rake and redistribute what is already in the bed rather than to add a fresh layer every spring.

Build a smaller patio. Cost scales in the base as well as the surface, every extra square foot is extra runoff on a lot that is not getting bigger, and oversized patios read as empty rather than generous. Mark it out with a hose, put the real furniture on it, and live with it for a week before anybody quotes.

Fence the need rather than the boundary. Privacy on a patio, containing a dog, screening one window — each is usually satisfied by a fraction of the perimeter. It is frequently the largest available saving on a fence job and it is almost never proposed.

Fix the grade before you buy a product. Drainage is a grading problem before it is a pipe problem, and retrofitting drainage under finished hardscape means lifting the hardscape. Order matters more here than anywhere else in the yard.

And do nothing for a year, deliberately. Watch where water goes in the worst storm, where the sun actually falls in August, and which corner of the garden you never walk to. That information is not available in a February design meeting and it is free by the following February. It routinely changes the plan, and always in the direction of spending less.

Questions this calculator answers

How much mulch do I need, and can I put too much down?
Area times depth divided by 27 gives cubic yards, and the mulch calculator shows that arithmetic. Yes, you can put too much down, and this is the one landscape material where more is worse. Penn State Extension: "Apply a 2- to 4-inch layer of organic mulch and no more; use less if the soil is poorly drained." And for fine material: "If using finely textured or double-shredded mulch, use 1 to 2 inches since these materials allow less oxygen through to the root zone." The mechanism is oxygen — "air may not penetrate the mulch layer and the underlying soil becomes depleted of oxygen" Keep it back from the trunk: 3–5 inches for a young tree, 8–10 for a mature one.
How deep does a patio base need to be?
The published minimums in ICPI Tech Spec 2 — Construction of Interlocking Concrete Pavements (© 1995 ICPI, revised February 2020) are 4 inches for a pedestrian patio and 6 inches for a residential driveway, both on well-drained soils. Then the adjustment: "In colder climates, continually wet or weak soils will require that bases be at least 2 to 4 in. (50 to 100 mm) thicker." Depth follows the load, the soil and the climate — never the paver on top. Read as the PDF republished by an ICPI member distributor. ICPI has since merged into the Concrete Masonry & Hardscapes Association and icpi.org redirects to masonryandhardscapes.org, so the member mirror is the copy we were able to retrieve on 5 September 2026.
Does a patio have to slope?
Yes, deliberately. ICPI Tech Spec 2 — Construction of Interlocking Concrete Pavements: "Slopes should be a minimum of 1.5%." That is roughly two inches of fall across twelve feet, which is HyreYard arithmetic on the published percentage. "Nice and flat" is, taken literally, an instruction to build a shallow basin — and standing water works into joints, moves jointing sand and goes through freeze-thaw cycles right at the surface.
How deep should fence posts go?
Deeper than the local frost line, and that number is not in any national document including this one. The frost line itself is not in the model code. It is set locally in Table R301.2 by the adopting jurisdiction, and it is the number your building department publishes for your county. It ranges from nothing in the warm south to several feet in the north, and it is the single figure that decides how deep a post or a footing has to go. The model provision, IRC R403.1.4.1, frost protection as reproduced in the Indiana Administrative Code, 675 IAC 14-4.4-43, requires that supports be protected from frost by one or more of: Extended below the frost line specified in Table R301.2(1); Constructed in accordance with Section R403.3; Constructed in accordance with ASCE 32; Erected on solid rock. And: "Footings shall not bear on frozen soil unless the frozen condition is permanent."
Do I need a permit for a fence, a wall or a patio?
Often not, and that answers less than people think. The model administrative list exempts "Fences, other than swimming pool barriers, not over 7 feet (2134 mm) high." and "Retaining walls that are not over 4 feet (1219 mm) in height measured from the bottom of the footing to the top of the wall, unless supporting a surcharge or impounding Class I, II or IIIA liquids." and "Sidewalks and driveways not more than 30 inches (762 mm) above adjacent grade, and not over any basement or story below and are not part of an accessible route." Then it says: "Exemptions from permit requirements of this code shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this code or any other laws or ordinances of this jurisdiction." This is the sentence people skip and it is the whole point. Not needing a permit is not permission to build it wrong, and it is not permission at all under zoning, a deed restriction, a homeowners association covenant, or an easement. Those are separate instruments with separate consequences, and none of them is waived by a building-permit exemption. Note also that the wall figure is measured from the bottom of the footing, not from the ground you are standing on.
What is the single most useful free thing I can do before buying hardscape?
Look your parcel up on Web Soil Survey, published by USDA Natural Resources Conservation Service. A parcel-level lookup of the mapped soil, its drainage class, its hydrologic soil group and its shrink-swell potential. It is free, it takes about five minutes, and it is the cheapest useful thing a homeowner can do before buying hardscape. It is a survey map, not a site investigation of your lot. It informs the hardscape line (thicker base on wet or weak soils in cold climates), the drainage line (how much runs off) and the planting line (whether roots will sit wet) at the same time.
My hardiness zone changed — is that real?
The map was revised. USDA Agricultural Research Service released a new Plant Hardiness Zone Map on 15 November 2023, built from 13,412 weather stations over 1991 to 2020, against 7,983 previously. "About half of the country shifted to the next warmer half zone, and the other half of the country remained in the same half zone." The publisher attached a caveat that is usually stripped off when this is quoted: "The developers cautioned against treating the changes as a reliable indicator of global climate change, because they also reflect more sophisticated mapping methods, many more weather stations, and the inherently variable nature of extreme minimum temperatures." And remember what the map is: The map plots the average annual extreme minimum winter temperature — a single cold night in an average year. It says nothing about summer heat, humidity, rainfall, soil, or how long your winter lasts.
Why do your cost tools not have any prices in them?
Because we hold no dataset of yard prices, for your area or any other, and a default figure would be an anchor with nothing behind it. Every cost field starts at zero and stays there until you type a number off a bid. It means the tools cannot tell you whether a quote is fair — and it means nothing on this site is a quote.
What is the compaction factor in the gravel calculator?
Compaction is a real volume change and ICPI requires the base to reach 98% of standard Proctor density. The ratio between the loose volume you buy and the compacted volume you end up with depends on gradation, moisture and the compactor, and there is no published national figure for "crushed stone". Twenty percent is our planning allowance, not a measurement of your quarry. It is labelled as editorial on every page that uses it, and you can change it.
Can you tell me whether my tree is dangerous?
No, and neither can any website. Tree work is governed by consensus standards — ANSI A300 — the industry consensus standards for tree care operations and ANSI Z133 — the safety requirements for arboricultural operations, applying to employers and employees engaged in tree work, with Tree Care Industry Association as secretariat — and assessing a specific tree needs a qualified arborist who has looked at it. tcia.org returned 403 to automated retrieval on 5 September 2026. The titles, scope and secretariat are recorded as consistently published by TCIA; no clause text is quoted here, because we did not read the standards themselves. Anything near a power line is a utility matter, not a homeowner one.
Does HyreYard do the work, or recommend someone?
No to both. We do not landscape, pave, cut trees, build walls or fences, install irrigation or sell materials, we rank and refer nobody, and we take no referral fee. That is exactly why these tools can conclude that you should buy less mulch, build a smaller patio, fence only part of the boundary, or do nothing for a year and watch where the water goes.

  • ICPI Tech Spec 2 — Construction of Interlocking Concrete Pavements (Interlocking Concrete Pavement Institute, retrieved 2026-09-05. © 1995 ICPI, revised February 2020. Source of the base thicknesses, the compaction targets and lift depths, the bedding thickness and material specification, the edge restraint requirement and the minimum slope. Read as the PDF republished by an ICPI member distributor. ICPI has since merged into the Concrete Masonry & Hardscapes Association and icpi.org redirects to masonryandhardscapes.org, so the member mirror is the copy we were able to retrieve on 5 September 2026.)
  • WaterSense: outdoor water use and labelled irrigation controllers (US Environmental Protection Agency, WaterSense, retrieved 2026-09-05. Source of the national landscape irrigation volume, the share described as wasted and its attribution to methods and systems, and the published savings figures for labelled controllers.)
  • Updated Plant Hardiness Zone Map (USDA Agricultural Research Service, retrieved 2026-09-05. Released 15 November 2023. Source of the station counts, the period, the half-zone shift, the publisher’s own caution against reading it as a climate indicator, and what the map measures.)
  • Mulching Landscape Trees (Penn State Extension, retrieved 2026-09-05. Source of the 2 to 4 inch depth limit, the 1 to 2 inch limit for fine material, the oxygen depletion mechanism, the trunk flare clearances and the list of benefits.)
  • Web Soil Survey (USDA Natural Resources Conservation Service, retrieved 2026-09-05. Parcel-level mapped soil, drainage class, hydrologic soil group and shrink-swell potential. Free. A survey map, not a site investigation of your lot.)
  • Nonpoint Source: Urban Areas (US Environmental Protection Agency, retrieved 2026-09-05. Quoted for the mechanism by which impervious surfaces increase the volume and velocity of runoff. The page publishes no runoff percentage and neither do we.)
  • Work exempt from permit (fences, retaining walls, flatwork) (Model administrative provisions, read as reproduced in a state-adopted building code (Texas Windstorm Insurance Association Building Code, 2024, section 105.2), retrieved 2026-09-05. We did not open ICC’s own library. This is a state adoption reproducing the model list, read through a code-hosting service. Adoption and amendment are local, and adopting jurisdictions amend precisely these thresholds.)
  • Section R403.1.4.1, frost protection, as adopted (Indiana Administrative Code 675 IAC 14-4.4-43, published by Cornell Legal Information Institute, retrieved 2026-09-05. Source of the four frost protection methods and the prohibition on bearing on frozen soil. The exception thresholds in that text are Indiana’s own amendments and are not the model numbers — which is itself the point.)
  • ANSI A300 and ANSI Z133 tree care standards (Tree Care Industry Association, retrieved 2026-09-05. tcia.org returned 403 to automated retrieval on 5 September 2026. The titles, scope and secretariat are recorded as consistently published by TCIA; no clause text is quoted here, because we did not read the standards themselves.)
