The coast should be the most developed region in kenya, them having been interacting with and trading with the rest of the world eg portuguese, chinese, arabs, british etc for centuries. They were even ruled for over 100yrs as part of the omani empire. They were exposed to the rest of the world unlike inland kenya which was discovered "just the other day" (1890s).
The coast should be east africa's "french riviera". But alas the coast claims to be a marginalized and undeveloped region even after being exposed to "civilisation" for over 500yrs.
