Madrid's grades
In Madrid, many homes and studios sit on the slopes above NM-14, reached by drives that are short but steep. Gravel slides downhill, ruts form where tires spin, and summer storms send water straight down the driveway toward the highway.
What a Madrid hillside drive needs
- A path for water above the drive. An uphill ditch or swale catches runoff before it crosses.
- Cross-slope. The drive tilts slightly toward the ditch so water doesn't run its full length.
- Firm subgrade. Cut to solid ground — not loose fill pushed over the edge.
- Thin, well-compacted base lifts.
- Hot-mix asphalt rolled thoroughly, with extra care at the curve.
- Supported downhill edge. Compacted shoulder and rock where water leaves.
At the highway
Where a drive meets NM-14, an asphalt apron keeps gravel off the road and gives a clean entrance. Work in the state right-of-way may need an NMDOT access permit; we'll check at the estimate.

Questions & answers
Is asphalt the only option on a steep drive?
On the steepest grades it's usually the most reliable. Chip seal can work on moderate slopes.
Can you get trucks up my drive?
We check access at the estimate and use smaller equipment where needed.
Do you need a permit at NM-14?
Possibly, for work in the state right-of-way. We'll confirm.
