What are these 2 called? Specifically the areas highlighted in yellow

The long opening is still part of the storm drain. I suppose if I had to get specific I might call it the mouth of the storm drain? Or the opening of the storm drain? The part of the kerb that is at street level is the gutter

Here in Ireland, the pavement is the road cars are on, while footpath is where pedestrians walk (US sidewalk).

The pavement near the curb that is not black I don't have a word for in US English. The wide metal drain is for handling massive amounts of water. I don't live somewhere with those but I'd probably call it the flood drain.

The area that you've labeled "pavement" is more commonly referred to as the sidewalk, at least in US English. Pavement is a more generic term for any paved area.

American here, the thing you have labeled as pavement I'd call the sidewalk. "Pavement" is a more general term for any surface covered in asphalt, concrete, stones, etc. So technically both the sidewalk and the road would classify as pavement. That being said, while researching for this comment I discovered that Brits call the sidewalk pavement, so you're not wrong.

Kerb is spelled Curb.

Just so you know, there are some differences between UK and US English that should be pointed out. In the US, "pavement" is a general term referring to the paving on a street, sidewalk, trail, or any paved space. Whats labeled as "pavement" in this image is called the "sidewalk". Also, "kerb" is UK spelling, while "curb" is US spelling.

The drain difference will be determined on how much water is expected to go there, which is related to pitch of the location, amount of paved surface at location etc. for example this could be at the bottom of a hill where a side drain only could be overwhelmed. Add the bottom drain and no standing water

I would call both portions of the picture, where water can flow into the structures below, a storm drain, and the concrete portion of the row beneath the curb, a gutter. (US)

Australia: Storm water drain and then ??? Not sure I have a word specifically for the other bit.

Concrete near the storm drain? Uneven pavement? Old concrete? I guess I’d say one of those or something similar if trying to describe what I’m seeing to someone. As others have said there really aren’t words for what you’ve pointed out.

A curb inlet and a gutter.

Back of curb and gutter inlet

Native speaker (USA) and had ZERO idea that it was spelled kerb rather than curb in other countries. And judging by how hard I had to fight autocorrect to write this, neither does my phone.

When you learn about the UK spelling of “curb” 😧

British English speaker who has worked in road maintenance here - the terminology here is a little mixed up between American and British English. The labels on the picture are mostly British English (pavement instead of sidewalk, kerb instead of curb) but storm drain isn’t really used in British English. Most would just call it a drain or road drain, though the correct word is actually ‘gully’ (and gully grating for the slotted cover.) The concrete area is very rare in the UK, but gutter or side channel would both be acceptable, I believe in American English as well. Technically we might call it a haunch, but that word might not be understood by most people. The opening in the kerb would be called a side-entry gully in the UK or maybe a kerb drain to people who don’t work in the industry, but ours never look like that - they usually have a grating like the gully as well to stop larger objects getting in there. I don’t know if there’s a different name for them in American English.

Between the street and the curb is the gutter

I think in my area of the world, the rail part is a “sick grind, bro”, and the flatter part is an “auuugh, ate it”. Kids will skateboard over these areas so you’ll hear all sorts of stuff coming out of their mouths. The actual terms are the “lip” and “gutter”. I find the more useful a section of THING is to a group of people the more likely they are to assign them vocal names. Not just regionally, but amongst hobbies and interests, a single object might have 2 or 3 different names.

I’m American and a civil engineer, I would call that a valley gutter and valley gutter inlet, but would generally call it a storm drain. As to why some have them and some don’t, it depends on the design of the road, when it was built, local conditions, surrounding development, and federal/state/local regulations.

Gutter for the part where it touches the road. The gap where water can flow through, I’d just call a storm drain

I'd call both the grated cover and the slot gullies. I'd probably call the one into the kerb a kerb gully, but ours (UK) aren't open as they would let large debris through. I'd call the area where the kerb and the road meet, a gutter.

Pavement is more of a material. I would call that the sidewalk. Also “kerb” should be spelled “curb.”

Over the drain yellow: drain hood. At street level yellow: gutter. Pavement is *sidewalk* in US English. Kerb is *curb* in US English. Where it says “street”, the material is *asphalt*.

I'm a civil engineer in the US. The opening is called a "curb inlet" (we spell it "curb" instead of "kerb"). The other part is called a "gutter". In general, concrete isn't as rough as asphalt, so having a concrete gutter allows stormwater to flow faster and drain off the road. This is more important on flatter roads. Having both a curb inlet and grate allows the drain to catch more stormwater.

The one in the curb is a “curb opening” or “curb opening inlet” and is part of the storm drain. The part that you have labelled “storm drain” might also be called the “grate”. Your other highlight is just the gutter. Some gutters are recessed below grade but others just run along the road side barely below the edge of the pavement.

As others have said, the lower concrete area is the "gutter" and the long slit is still part of the drain. However, "pavement" can really refer to any hardened or prepared surface. So the street and the sidewalk are both "pavement."

In my line of work, we call the shelf above the stormwater drain opening a “lintel”. The flat surface between the road and the kerb is a “gutter”.

Assuming you’re asking for British English based on the spelling of curb as kerb and stylization of sidewalk as pavement?

In America they call that a bike lane

Is there a subreddit related to road construction? The section leading to the storm drain is the gutter, but the curb adjacent to the storm drain, I am not familiar with that design. I reside in Canada. Oh, I see that's just part of the storm drain.

What you've labeled "pavement" is called "sidewalk" in the US. Pavement, in the US, is what the street or sidewalk is covered in. The dark-grey surface of the street is pavement. Technically, the concrete sidewalk is also paved, or covered in pavement. They're just different kinds of pavement (concrete vs . asphalt). The slot you've outlined is the main opening to the storm drain. I'd say what you've labeled as "storm drain" is a removable access grate to the storm drain. The area between curb and street is the gutter.

Raised side of road to meet the sidewalk= curb Low edge of road that channels water = gutter Hole that water drains into = drain

[https://codes.iccsafe.org/content/IPC2021P3/chapter-11-storm-drainage](https://codes.iccsafe.org/content/IPC2021P3/chapter-11-storm-drainage) I think the top yellow part is called a scupper, used for overflow drainage, and the side yellow part, as someone pointed out, is a gutter. The storm drain is the pipe that carries the rainwater, the metal part on top is probably called a traffic-rated cover.

Long opening is a *culvert*. The part of the street next to the curb is the *gutter*.

The part over the drain opening is the lintel. Similar to a lintel over a window

In Australia we call the part away from the drainage structure - kerb and channel. Kerb is the vertical portion and channel is the flat portion (where the OP ?? are ) that carries water. Yes the bottom of the kerb is used to contain water in the channel.

Thought this was r/civilengineering for a second. Yes, as some of the other responses say, I would call the part at grade with the asphalt a “gutter” and the concrete opening would simply be an extension of the storm drain.

It's spelled Curb, the hole above the storm drain is technically still part of the storm drain. The part in between the curb and the street is called a Gutter

From your spelling of Kerb and use of pavement, I'm assuming that you are learning British English? The right hand side label would be gutter, the left hand label I don't think there is a word for it outside of civil engineering. Also that type of set up is uncommon in the UK, looks more American in style.

U.S. native here. I would understand what you meant if you called what is labeled as pavement, the pavement. But I would call it a sidewalk. Pavement is a more general term for any flat expanse of concrete meant to be walked on. The area between the asphalt and the sidewalk is a gutter if, like the one pictured, it's shallow, lower than the street and the sidewalk and meant to carry away water. If there were no sidewalk, and it just slooped away from the road with no curb or gutter, I'd call it a shoulder. Rural roads and highways often have shoulders instead of gutters. The step up at the edge of the sidewalk is a curb. I pronounce it the same as people who spell it kerb. The storm drain or drain is a storm drain or drain for short. Occasionally someone calls it the sewer, but technically the sewer is the pipe it leads to.

I feel like the slit in the kerb is also the drain

American here. I would say the street is where the cars go, and the sidewalk is where the people walk. The surface of both or either is called the pavement: in this case the sidewalk has a concrete pavement, and the street has a macadam pavement.

The metal part of the drain with the lines across it is a grate. Storm grates get clogged.

In my general understanding the long narrow opening is the storm drain. The metal part indicated to be a storm drain is actually a sewer grate or drain cover.

That is called the gutter. Technical term: street gutter. And that other part is called a curb, which means to restrain or keep in check, because it "curbs" the sidewalk. I'm now not sure which is more infuriating: when Americans mistakenly call it a "curve" or this insulting, completely unnecessary "kerb" word I'm seeing for the first time in my 49 years on this planet.

apparently kerb is an british spelling but never in my life have i seen that. I always use curb

Civil engineer here. As others have pointed out already, the concrete next to the road is called the curb and gutter. The gutter is outlined in your picture. In the industry, we call that kind of storm drain a catch basin. The outlined part is a curb cut, specifically an overflow inlet. It allows especially large rainfalls to quickly drain away. Curb cuts don't have to lead to a storm drain, but can also empty into a ditch next to the road.

Norwegian Kantstein sikring translated too Curbstone securing the asphalt patch next to the Curbstone

Since when is curb spelt kerb???

Curb stones

 KERB-y

Are these words you really need to know? Native speaker, can't say id ever need to know this unless I worked road construction..then you'd learn those terms on the job

If it's of manmade materials, it's a gutter. If it's natural material, it's a ditch. The aperture is a storm drain. Usually they have metal lids on top called access points to open up and clean them out. The pathway inside the drain is a culvert.

The part on the right is a gutter. The big opening is the mouth of the storm drain while the part you labeled as storm drain is the grate.

Kerb

Sorry I meant gully

Gutter and storm drain. The one you have labeled as a storm drain is a sewer grate.

I would call whats labelled here as the stormdrain/drain as either drain or grate, and call the opening in the side the storm drain. I think this is because the term 'storm drain' doesnt really exist in the UK where I am from, and neither does the gap in the kerb. The bit at the foot of the kerb is the gutter as generally all the litter gets pushed to the side by the road and roads are designed to funnel the water to the side like a gutter.

The concrete piece leading up to the storm drain is a gutter the gap on the side is just part of the storm drain it's there incase leaves and debris block the grate the water will just go in through the side

kerb

I don't even know that in my native language

The shoulder is the side of the road that's past the white lines on the sides.

The side of the road lol🤣

\*curb. left '?' is sitll the drain/storm drain. right '?' is the gutter portion of the street since it is slightly recessed from the pavement. though sometimes they are flush (at the same level), it is the same.

You might hear people call the storm drain a “grate” and some people might call the entire length of concrete between the street and the curb a “gutter”

Hello, I am a civil engineer, here in the US these are what we call each part: The concrete (light grey part) is actually the sidewalk. The pavement is the asphalt (black/dark grey part) in the street. The concrete between the curb and the pavement is called the gutter. One person asked if that was only if it were lower than the pavement, and it always will be because otherwise you would just put the pavement up to the curb. The opening into the storm drain is called a grate, the whole box down there is called a drop inlet, and the concrete on top is called the deck. Although most people don't know that, so your best bet is just to call it the top.

In the USA, if someone pointed to the drainage area, I would be comfortable calling it a sewer, being that whatever enters here would most likely end up in a sewer or something resembling one , whether or not sewage or rainwater flows through it.

Curb is spelled curb. NOT KERB.

Kerb? Isn’t that spelled curb?

kerb is funny ngl

I’m an English speaker born in the US, I would use the following terms for the things highlighted in yellow: - the long opening is called a “curb opening inlet” (according to a municipal services website) - the part in the upper right is called a “gutter”

I've no idea what that long opening is, can't recall ever seeing anything like it. the part that runs along the edge of the road and collects the water, I'd call it a drainage trough. I've seen some people refer to it as a gutter, but for me (Canadian) that word makes me think of roof gutters.

Nah it's a skateboard collector dawgie 🤙

Clown catcher 3000

I am not native english speaker but i dont know what they are called in my native language :D

Honestly, I have no idea. It’s not something I’ve ever needed to talk about

Local depression

Kerb and gutter

There might be a technical term for the things you’ve highlighted used by the road commission or the like, but most native speakers have no words for these. You already know the same words most native speakers use; the road, the sidewalk, the kerb/curb, the storm drain.

The yellow area on the right is the gutter. Some streets have concrete gutters, and some are asphalt like the rest of the street. The slot in the curb would technically be called a curb inlet, but more commonly speaking, it's just part of the storm drain. Also, your "pavement" (UK) would be called a sidewalk in the US. Here, the pavement is the material on the actual street.

The bit running alongside the kerb I would call the gutter. Not sure about the bit above the drain though.

curb and storm drain

In the UK we might refer to that as a storm drain as you've labelled but if you want to refer it to your local authority for a fault etc. then they will talk about it as a "road gully". I speak from experience having done just that.

Hindi is my native language, searching friends who help to learn English. I want to read Leo Tolstoy 23 tales.

The lower yellow section is technically called the channel, but usually called the gutter. The higher yellow section, I don't know if it has a specific name. Maybe "overhang" or "inflow cover" or something like that. It's just a bit of concrete. Why do some roads have them and some don't? Cost and maintenance, basically. It's cheaper to build a road without curbs and proper gutters, but it doesn't direct stormwater into the drain as effectively, meaning that water is gonna pool on the road and likely seep into the surface, damaging it and causing potholes. That being said, not all roads need to be able to move stormwater into the drains as well as others. All roads are part of a complex, branching stormwater management network, and if your road doesn't get fed stormwater by any other roads, it only has to deal with the rain that falls on it (and possibly some of what falls on the buildings around it). The engineers that designed the road probably said something like "okay, the kerbless design will be 100% fine for the once-in-10-years storm, but in the once-in-100-years storm, water will pool on the road and possibly cause some potholes. It will save us $x million over 100 years to not build the kerbs, and the potholes will cost less than that to fix, so it's not worth building the kerbs here." We just moved house and we have kerbless roads, but we're about 100 metres away from a stormwater retention basin & a *massive* swale (basically a gutter, but made from dirt & grass & usually bigger). If we get a huge storm, water's not gonna back up on our street unless a) it's falling ridiculously fast and it can't flow down the road before more arrives, and/or b) the storm lasts long enough that the retention basin fills and the roads/drains/swales/etc. that feed it all flood. So it was probably unnecessary for our neighbourhood. In non-stormwater news, having a kerb means drivers tend to stay further towards the middle of the road, and pedestrians are less likely to cross the road, because psychology I guess. It's also easier to park on the nature strip when you have kerbless roads. These can all be pros or cons depending on the specific road in question.

Thanks everyone. You’re very helpful.

The gutter is upper right. The storm drain is paired with a curb (kerb) opening inlet. See https://www.jetblast.com/blog/parts-of-a-storm-drainage-system/

Kerb, drain, gutter

What you call a pavement here is actually the sidewalk. Pavement is usually the finished product of a road built using asphalt. Nothing about that sidewalk is paved, it's concrete that gets poured and leveled.

Well, this thread is staring to circle the drain. Thank you all for the robust conversations… and reports. How nice of some of you to plug up your own holes.

'kerb and channel', 'side entry pit'

Isn’t it curb?

If I had any say in this I'd call that slit above the storm drain a "penny visor".

I would say that the concrete part of a curb connected to the street is called a gutter.

The open opening is where the murder clown lives.

You dont even know the word for it in your language bro😭😭😭
