Thank you for this lengthy bug report, I can definitely fix a lot of this.
I'll just add a curve that's shallower to cover the back without clipping through the plants.
Originally the house was there as that was the exact height needed to boost into window and was left as an easter egg for my friends, kinda meant to be like a toy house, was going to leave other toys and bits around the city to make it feel like the civilians left in a panic when the cargo on the train derailed. (thinking like warning sirens went off or something - but I wouldn't want that to be there at the start of every match on my map as that'd be just horrible for people to deal with like the helicopter on d1 it's loud and obnoxious)
I can try to rework the coping of the blue wall to make the bomb stick out a little more.
Water is very buggy in cs, that shouldn't be happening but good find I'll try to work out a solution.
Thank you working with a small map you need creative solutions to problematic areas without making options too strong, that jump spot had too many iterations before it felt just right. (The little trim used to allow you to peak over the wood into the sight from an incredibly dirty corner that you could easily get to while the bomb was being defused)
I used to have it so you could go up and through the glass onto the second level but that gave players a headache when trying to retake the map.
I kinda like the crouch spot as it stretches out the player model further allowing for a cheeky one round strat which players will know to look for. (thinking the cts smoke directly outside the door boost one man up and have the other hide by the exit into the garden / smoking area peeking when the player up top feels there is too much pressure)
I might remove the boost or at least add something so players know they need to crouch there.

Ohh I was high and thought it'd be hilarious to fill the taco with human meat, plus it's a little nod to the pilot of bobs burgers. (I still enjoy it tbh)
After all when you create something you gotta make it for you, if you aren't having fun with a project it'll get stale. (If you nade taco you can launch the bodies)

Did you find the deagle?

Sorry I was searching for bugs not deagles ^_^
You didnt mentioned the render distance in your answer, but please fix that too, its weird if people shoot at you because the object you hide behind is invisible for them.
Kinda like wallhack.

Oh you said something about being able to launch the bodies, attention there.
If they have hitboxes they could block weird when they lay on the ground, I had the same problem with a prop_physic once too.

I fixed all of it already, and nah you walk straight through them and it'd be impossible to take them to a site for them to hide the bomb. Unfortunately during fixing things I reworked some geometry to make it cleaner and left a hole, will be posting the update very soon and crediting you in the update's description.

Spotted another prop with a small draw distance, it doesn't affect cover but it does feel strange.

Good to hear that the map is getting in even better shape.

I intend to keep working on it for another month and will test player suggestions both for gameplay and visual things.

I think gameplay is mostly where I want it but I'm always open to new ideas.

I do want to try to organise a proper 5vs5 as the map has enough layers to it for counter play, I should hope that I've done my job as a map designer so players won't just default to a winning strategy without any way of stopping them.

I still need to add ambient noise but for learning the map being able to hear each different surface type is very useful as you will know exactly where someone is a lot of the time based on their footsteps.
