We finally got some straw for the sloping portion of the meadow. You can see in the pics below that after we removed the raised vegetable beds, a heavy rain storm started the erosion issues I was worried about.
We also got some more mulch to finish cutting in and mulching the edges where the raised vegetable beds were. Still have grass popping up that I'm hitting with the glyphosate as needed. Total time spent: about 16 hours Total cost with additional mulch and a straw: $174
