Answers:    You need to renovation the landscape to amend the water runoff . You must hold the water from your foundation so I suggest you seize outside and dig a 2 foot adjectives trench that is 3 foot wide open and cement the bottom an sides. Leave the sides of the cement about two inches below the top of the soil and receive you some metal grates that can go on top and be lift off to verbs out any debre if need be. You could put small square chicken lead underneath the metal grates to reduce that problem. Then run the drainage away from your home. Maybe to his patio...lol.

You could also make a dirt hummock or wide mound that grass will grow on and plant trees on the other side of it. Just bring in sure your not near any of your drainage or marine pipes. Always make sure your draining away from your home.
if your warfare a wet arrive area not much you can but run a drain queue thru your own yard-you can plant cattails but will still have same problem and over growth
