The route goes through, around, or over the Hollywood Hills. There will be steep grades and/or expensive tunnels running transit lines through hills.
If you choose the steel wheel on steel rail, tunnels wlll be needed. If you choose rubber tires on steel or concrete rails, no tunnels will be needed.
The only reason monorail is still a viable option is because rubber tires allow them to operate on much steeper grades than steel wheels can.
Light rail trains in general can climb 6% grades with standard rail designs. Monorails could easily climb 12% to 20% grades. What they choose to use will affect how they design the transit line, no question about that. When all is planned and debated politically, those in power will usually choose to build the cheapest option for the least amount of money using the cheapest qualifying equipment meeting the minimum operation requirements possible.
Good luck.
