Severe Drainage from road to Home
Channel drains would work but where are they going to dump? Can you run the PVC around your house or are you going to have to go with French Drains. Topographical map of your property is pretty much needed unless it's just plain obvious where the water will lay - and where it has to go.
Here in the low country of SC, pretty much every road, even if it's level with or a tad lower than your yard, will have a swail or "ditch" for lack of a better term, adjacent and parallel to it. Reason being - we get rains that dump 5 inches in one hour at times when these depressions move through. Of course our soil is pretty sandy and what pools on the yard will perk in an hour even after a bad blow. Well - not like Hugo. Anyhow-
Sounds like you might look into having some grading done - of course you'll have to see if there are ordainces and such that prohit common sense in your area, But hopefully, your ground perks well and you'll be able to create a swail to protect your investment. It would be even better if you could redirect that water, but thats a whole different can of worms. Check to see if there are any water easements involved. Also - width of right of way. Five feet below the road surface at 75 foot away is a might much. Does the otherside of the road have the same topography? Are there storm drains? I can't imagine someone laying out those plot plans and not compensating for the run off. Are you in the country, or development? Just curious on that.
If you don't have time to do it right, when will you ever have time to do it over?
