So I spent all night editing SV to be compatible with LN and Ambitions (mostly because I'm not good enough to use CAW yet)... I focused more on having the entryways to buildings positioned on the most level part of the terrain because lining it up with the roads didn't make much sense if there was a 3ft cliff in front of the door (the Sims wouldn't be able to enter that way anyways). Any houses/families I had to move for lot placement, I relocated in another part of town so everything from the base game is still there. I ended up with 5 apartment buildings, 3 dance clubs, 3 lounges, 1 sports bar, 1 watering hole, a dive bar, and everything from Ambitions (except the Laundry mat because I never use it). I'm gonna try my luck with Barnacle Bay next!
If you click on the pictures, it'll show you bigger ones.On Twinbrook Lane I was able to fit 4 64x64 Lots and 2 50x50 Lots - I've marked the entryways with thick lines so you can tell where it's level.
1 50x50 Lot between Twinbrook and WaterFall Way.
There's a Junkyard in the empty lot by Stoney Falls (top right of pic)
I relocated Goth to the ever popular 15 Summerhill Ct and replaced their lot with a 64x64 for Plumbob Pictures. Further down Skyborough Blvd I was able to fit Waylon's Haunt on a 50x50 Lot and the entryway levelly faces the road:

Here's a quick shot of Summer Hill Ct:
On Redwood Pkwy No Larger Sized Lots would fit besides the 40x30 that are thereI moved Agnes to 415 Skyborough Ln and moved the Single Moms to Sunnyside Blvd.
I put the 2 empty houses in that area on the end of Redwood Pkwy so the apartment buildings would be closer together.
Oak Grove was a big waste from all the hills. Most of the original lots had to be deleted to make room for useful ones. It helped the apartment area get more of a city feel by dumping in the rest of Ambitions.
At the top of the picture you'll see I deleted the empty house on Sunnyside Blvd,I moved it to an empty lot by the Stadium, and replaced it with a 50x50 lot (Eugi's. Across the street (behind the Art Gallery) I fit a 40x40 lot for the Grind:
