I have a house in Northwest Indiana, it's on a crawl space with a sump
pump. Due to flooding 2 years ago (Katrina) the crawl space was
filled with water and the sump pump couldn't keep up, and water
entered the house causing $$$ damage. What can I do to avoid this
situation in the future? Add another pump? dig up the crawl space?
Raise the house? Can anyone give me an idea of house raising costs?

Thanks
