Flooding in crawlspace. Other solutions besides encapsulation?

[Jimmy Chao]

My crawlspace is constantly flooding from heavy rain. From what I've been told, the soil in the region (Kansas City) soaks up water, which is how its getting in crawl space. A foundation/water proofing guy told me the best solution is encapsulation with sump pump which is going to cost nearly 20k. Has anyone else with crawlspace dealt with this problem and what fixes did you do?
