Confederation Line (Stage 1) | In Service 1.0

[MalcolmTucker]

The city could try consolidating a few lots deep behind commercial buildings as the come up for sale on bank, and then eliminate street parking to retain traffic lanes when building dedicated transit. I'd bet it would be the most economical politically feasible option.

During special events buses could run southwards from Landsdowne to various points partly on the exclusive ROW while the lrt vehicles are concentrated on the northern segment to provide surge ppdph.

This is what I was thinking. You don't need to park in front of the stores, but to keep the same access having parking 1 block on either side is essential (technically not, but in our case for our region it is). So Kent and O'Connor become the car streets with ample parking... with that I think it could work and I am sure there are some examples somewhere in North America.

Why not build underground parking with new commercial and residential space above.

Because we don't have 50 years and $50,000 per parking spot. But nothing stopping that from happening organically.

I mean in the future. Every new building along certain streets must have public underground parking. Then someone wanting to walk to another shop can, and their car is safe.

I never understand why retailers feel they need to having parking spots in front of their store. How often does someone get a parking spot in front of the store they are going to? Usually you end up parking a block or two away and walking.

Underground parking is hard to fit in developments below a certain footprint though. By necessity you'd be pushing development to projects that stretch half a block or more.

The lot buy up strategy is just a sop to the business owners along bank to reduce potential opposition. Don't expect super extraordinary results from it, or any other parking strategy.

Agreed. I have often thought that land used exclusively for parking should be taxed at a high rate per square meter of land to encourage underground, rooftop and multilevel parking. The first two would not be taxed at a premium as the land is primarily used for something else and the last would, but the premium would effectivly be divided over the number of levels of parking. Existing developments could be grandfathered over a period of time to give them time to make the changes, but new developments would be taxed immediately to ensure they change their plans accordingly.

Incentives should also be added for neighboring parking lots (especially retail parking lots) to share an entrance to reduce the number of intersections.

Its surprising what can be done in a small space. As discussed in another thread, this project has 3 levels of underground parking in only about 3600 sq. m (about a quarter city block).

[MalcolmTucker]

Still the entire frontage on Bank + 30 m if the developments longer (front) side fronted Bank. For comparison the block with the Shoppers and Metro in the Glebe is 66 m. (The lot you linked to has ~98 m of frontage on Richmond).

Also short block lengths will limit train lengths, unless a good number of intersections are made right in, right out only.

[lrt's friend]

If trains are running on the surface on Bank Street or any other street, you do not want them to be Confederation Line length. The vehicles have to be scaled to the situation and they cannot be so long as to impede even pedestrian traffic.

You are right. The Glebe has shorter blocks. I was looking closer to downtown where most blocks are about 75 or 80 m.

Also short block lengths will limit train lengths, unless a good number of intersections are made right in, right out only.

Very true. Another good reason for tunneling under Bank.

To be replaced with a visually prettier design that will have the same human-environmental flaws as the ugly things they replaced.

Lumber floats at Lyon station

Matthew Pearson, Ottawa Citizen
Published on: August 19, 2016 | Last Updated: August 19, 2016 4:44 PM EDT



On a visit to the Glue Pot Pub one afternoon this week, I noticed a strange sight down in the deep hole where a future entrance to the Confederation LRT’s Lyon station will be: Water. And lots of it.

Stacks of lumber and other construction material appeared to be floating, while a single worker — standing on a makeshift raft made from a large piece of plywood — used a huge hose to suck the water up to a hydrovac truck parked above on street level.

It was the loudest vacuum I’d ever heard. The server said the sound was actually giving her a headache. But construction along this stretch, as Kelly Egan wrote earlier this summer, is responsible for lots of headaches.

I didn’t see any other workers in the hole that afternoon.

Given the record amounts of rain that had fallen over the previous weekend, perhaps water in the hole wasn’t surprising. But I asked the city for an explanation anyway.

Here is the written statement supplied by media relations and attributed to Steve Cripps, the director of the rail implementation office.

“Lyon Station experienced some water infiltration over the weekend due to a combination of heavy rainfall and existing ground water infiltration. Ottawa Light Rail Transit-Constructors (OLRT-C) used a hydrovac truck to remove the water from the Lyon West entrance to allow construction to continue. The water was removed in one day on Monday, August 15, 2016. This event does not affect the construction schedule and the weekend rainfall event has not constituted a delay to construction.

“This week, OLRT-C teams are working on the elevator shaft and, next week, will be backfilling and pouring slabs.”

Cripps’ response prompted me to ask a follow-up question about whether other LRT construction sites were also affected by the “combination of heavy rainfall and existing ground water infiltration.”

I just received this reply and the photo above of “water removal” at Pimisi station.

“Pooling water is a common occurrence in construction excavation due to rainfall and groundwater infiltration. All construction sites around Ottawa would likely have needed to remove water following last weekend’s rain event. The Confederation Line is no exception. RTG (OLRT-C) teams remove groundwater on sites as required and monitor water levels to ensure no unusual or unexpected activity occurs.”
