Deteriorating cinderblocks at corner of foundation

My house was built in 1988, I moved there n 2002. Several years ago I had B-Dry put a system under my house (plastic drains and sump pump) because of water pooling under my house. There was also gutter drains going from my gutter into the ground which likely cause alof of my water issues. I removed those and ran plastic gutter drains above ground and away from my house.

At both the left side and rght side of my house i have a stretch of exposed cinder block above ground. At one corner of this cinderblock, I noticed that there was a section with erosion damage, likely from the running water. Digging into the ground there I found that the concrete cinderblocks at that section had deteriated (about 3 to 4ft) , so that the front part of the blocks (outside of house) were eroded away, but the back part of the block is still in tact under the crawlspace. This is the cinderblock that is just above the footer of the house.

I called a structural engineer to take a look. He inspected the area and his repair suggestion is to have a brick mason replace the damaged cinderblocks there or pour concrete to just fill all the missing cinderblock in.

I just wanted to check with those here to see if that seems like a valid repair for something like this? This is what the structual engineer I called suggested, I just hope that simply replacing the block there or pouring concrete is a sound structural fix. Maybe it is, I'm just really worried. He seemed to suggest it shouldn't be that expensive to fix, likely under $1000. I called a brick mason who the structural engineer was able to suggest to me, and they are coming to take a look in about 5 days to get an estimate. I've included some pics of the damage...

ICF Homes - Insulating Concrete Forms

You maybe able to clear enough space to use an insulated concrete form to repair the damaged section. (see the above site) Or maybe create your own form & pour concrete.

Before you do that, why was the sump pump & drainage needed? Is there a high water table? Solve the water issue before do the repairs.
