My husband is active duty navy so he has a very transient career.

As expected here, we operate in both English and French, but we have also made arrangements with the individuals in two ethnic communities and the local multicultural association to assist us with serving our international student clientele - most of whom speak Arabic, Mandarin, Portuguese, or Spanish.

I would put in a french drain at the bottom of the slope and run it to the fence.  

Don’t let the haters get you down French!

John, intriguing topic.I'd say Imperial Beach will be up and coming based on the Navy's plans to build a large SEAL base there (article) and due to the fact that it is the last relatively affordable ocean-front community in San Diego. 

If the problem is that the property is the lowest spot in the entire neighborhood, so that it is at the bottom of a lake every time it rains, then that is very difficult to fix.I might be willing to do French drains if the price of the house was really low, but I walk away from something where the drainage problem is due to the location and not really fixable.There is a lot of property available for purchase.

Woods basement suggested waterproofing, French drain and sump pump tie into our side French drain.

But, you are in that funky state with a legal system primarily based on French and Spanish codes and ultimately Roman law, as opposed to English common law like the other 49 states so I'm not really sure!?!?!

@Navi Veski - Thank you for the kind welcome.

(I am french so Sorry if here and the future my english is not good)
