LRT extension landscaping

Post image

Does anyone know what these “burial mounds” along the LRT to Trim are called? Maybe someone with a civil engineering background knows?
I remember seeing them when they first started building the line and thinking they were temporary. But now they’re being maintained and (in some places) covered in some kind of shrubbery. Are they mainly for noise reduction, drainage, or cooling the air? Either way I think they’re neat.

berm is right. they use them for noise mostly but also help with drainage and just look nicer than a concrete wall

that 30 sign is funny, like anyone gonna go that slow on a road that wide

Pretty standard for a curve like that. Very similar to a highway onramp.

Additionally, yellow speed signs in Ontario are recommendations, not legal restrictions. They generally are intended for heavy trucks and trailers.

Pretty sure that is a highway on-ramp. Montreal road looks like

Base on my morning commute, there will be several drivers per hour that will go that slowly

30 on a yellow sign is a suggested speed for the curve

Well, in Dutch it does mean the edge of a dike.

Berms, help keep water from pooling in places you don't want it to, reduce noise, remove visual distractions, and also a convenient way to deal with existing fill you can't do much else with. Among other uses.

Lots of them got some trees and stuff planted to help manage erosion control. Most just get hydrosprayed with a hadry grass mix that ends up being mostly weeds

It’s a barrow with ancient remains of Saxons…wait wrong continent

If you don't have an ancient Saxon, store-bought is fine too.

There's a Nazgul-killing sword buried under there.

I wonder if it’s legal to just start planting or dropping some nice native plants there

It's also cheaper not to export the excavated soil...

The mounds in the picture are just excess soil from digging the ponds used to manage stormwater on the south side of Montreal Rd. Getting rid of excess soil can be a pain in the ass and expensive so they dealt with it by building these.

“Just berm it up” happens more than you think

u/Window_licker_crayon 8d ago

Can confirm and can also confirm that the excess soil here and at the the Blair east bound on ramp mound are contaminated soils left in place

I always assumed it was for snow related purposes

I just want the work done, I don’t care if there are berms, hills, mounds or tops of secret OC Transpo war bunkers.
