Does anyone know how much to cost to build a block wall (70 ft. long, 4ft tall for 1st 25 ft. and 6 ft. tall for 45 ft.) in Los Angeles?

"I would build a foundation of about 15" deep and than build the wall on top."

Based on what? OP has not identified if the wall is free-standing or retaining. If it's retaining, there is definitely going to be permits required, and there is a standard enginerring requirements for footings and rebar.

You might need a permit...
I would build a foundation of about 15" deep and than build the wall on top.
If you are a skilled person it should take you about three days to complete the job.
I would higher a pro to do the job.
Good luck

If it is retaining wall, don't forget rebar - especially for the 6' section. In San Diego (and, I would assume, in other SoCal municipalities), the footing and other requirements for a retaining wall change once the wall exceeds 5'.

Also, a retaining wall will need to be permitted.

There are quite a few variables to take into account for a project like this, such as:
-Is this a free standing wall or a retaining wall?
-What kind of foundation is the wall going to have?
-Do you have a specific style of block that you want to use?
-Is the block going to be finished in any way/
-Do you want a material cost only or are you going to hire a professional to do this for you?

    If you are hiring a professional then you should probably just call someone in your area for a estimate as any pricing we throw at you could be way off and just confuse your expectations.
    If you are looking to build it yourself then I can give you a very rough estimate for the basic materials, the block and mortar.  You would need somewhere in the neighborhood of 350+ 8x8x16" blocks which, with mortar, would run around $600 plus tax and delivery.  Remember that is a minimum.  If you are just a weekend warrior and need to do any kind of foundation prep then you can easily double that number.

I hope this helps,
Ethan
