My house is a ranch with a garage (under) and driveway with very little pitch to the street. Worse yet, there's a 2-3" "lip" where the driveway meets the street - resulting in very large puddles which cover about 1/2 of the driveway (at the street end) whenever we get heavy rain.
The driveway needs to be repaved, but I want to make sure that the water problem gets addressed. I can't pitch it sufficiently from the garage to street because of limited clearance at the garage end.
I've had 2 paving contractors and one DPW engineer from the town look the problem - all 3 suggest putting in a trench drain to a dry well. The 2 paving guys would put it near the street, but the DPW engineer suggested putting it at the garage end. He suggested creating a "hump" about 1/3 of the way from the street to create enough pitch to the street - the pitch back to the house would be caught by the trench drain. His thought was that this was better than putting the drain right where the puddle forms as this would also catch run-off from the street and likely not drain well enough. Seems to make sense - my only concern is allowing water to drain towards the garage.
Any thoughts and/or experience with trench drains??
Thanks in advance.
