Retaining Wall in Sand
Hello All. I am planning on building a 3-4' high x 20' long retaining wall by next year. Live in a coastal area and my yard is basically sand.
Been researching a ton. I cannot find a definitive answer. Do I need to utilize 3/4 stone for the base/footing material? Or could I just use the sand that's there?

You will absolutely have to remove sand and replace with some type of compactable material. Sand is not a stable material to build on,

Per section R403.1 some kind of foundation is required. Given the unstable nature to sand I would suggest having the retaining wall properly engineered by a licensed professional. Retaining wall design requirements are in code Section R404.4.
