Coastal Considerations
Del Mar's coastal location requires careful well planning:
Saltwater Interface
- Distance from ocean — Properties within ~1/2 mile face challenges
- Depth considerations — Avoid over-pumping near coast
- Water quality testing — Monitor for salinity
- Inland properties — Generally no concerns
Best Candidates
- Properties east of I-5
- Del Mar Heights (elevated, inland)
- Valley floor properties away from coast
- Equestrian areas in San Dieguito Valley
Local Geology
- Alluvium: San Dieguito River valley
- Torrey Sandstone: Coastal bluffs and inland
- Del Mar Formation: Siltstone/sandstone

Wells on Record
San Diego
County
Based on California DWR well completion reports. Del Mar's average well depth is 310 feet shallower than the San Diego County average of 450 feet.
With 50 wells on record, Del Mar has a growing well infrastructure. The wide depth range of 18 to 400 feet reflects the varied terrain and geology across Del Mar's landscape. Shallower wells typically tap into alluvial aquifers near drainages, while deeper wells penetrate the Peninsular Ranges batholith, primarily granitic and metamorphic rock to reach more reliable water sources.
At an average depth of 140 feet, drilling in Del Mar typically costs between $6,300 and $10,500 depending on formation hardness and casing requirements. See detailed well depth data for Del Mar →
Drilling Conditions in Del Mar
Well drilling in Del Mar typically encounters the Peninsular Ranges batholith, primarily granitic and metamorphic rock. Most wells can be completed in 1-3 days under normal conditions. The relatively moderate depths keep drilling costs reasonable, though rocky formations can slow progress.
San Diego County requires a well permit from the Department of Environmental Health (DEH) before drilling can begin. The permit process typically takes 2-4 weeks and costs $800-$1,500 depending on the parcel. We handle the entire permit process for Del Mar properties.

Frequently Asked Questions
Can I drill a well near the ocean in Del Mar?
Properties very close to the ocean face saltwater intrusion risks. Inland properties (east of I-5, Del Mar Heights, valley areas) are generally excellent candidates.
How deep are wells in Del Mar?
Wells typically range from 150-400 feet deep. Valley floor locations often find water shallower.
Do you work on equestrian properties?
Yes, we specialize in horse property wells including arena watering, paddock irrigation, and barn supply systems.
What about the Del Mar Fairgrounds area?
The fairgrounds area is close to the coast and river. Wells are more suited to properties farther inland.
