You're not gonna like me this week!
But, why do they need a retaining wall for a storm water swale? That's stupid. And not what the civil engineer intended when that community was planned.
No wall is needed.
Take the old wall out and dispose of the waste. Then taper the grade down so it meets flush with the rip rap. And next, import more rip rap and widen the swale by about 18" on each side.
A wall along a swale is just stupid, that is something that probably 22 years ago the 72 yr old HOA board president came up with.
