The house my wife and bought had a driveway taken out by the previous owners and elevated landscaping put in where it was. There are some drainage issues, so I'd like to use gravel with a stability grid if possible. The house is in an urban setting and there already is a ramp over the sidewalk, so I'd really like to have some off-street parking. The lot is elevated about 2 -2 1/2 ft above the sidewalk where the entrance was. The length of the drive is only going to be 25 ft, so I'm not sure how to cover the elevation change.
