Planning for San Bernardino Properties
Local drainage work has to account for intense summer heat, compacted soil, short periods of concentrated rain, irrigation, block walls, finished patios and the elevation changes found toward the northern foothills. A reliable system also needs a discharge point that can be inspected and maintained.
Before digging, the route should be checked for practical access and utilities. Work that affects a public right-of-way, curb, sidewalk or municipal drainage feature may involve additional requirements.

French Drain Repair — FAQs
How do I know if the drain is clogged or collapsed?
Slow discharge and sediment at the outlet often indicate blockage. A localized depression or sudden failure can point to a crushed or separated section. Selective inspection helps narrow the cause.
Can only part of the system be repaired?
Yes, when the failure is limited to an outlet, fitting or short damaged section. Systems with contaminated aggregate, failed fabric or poor overall slope may need partial or full rebuilding.
Should roof water run into a French drain?
Concentrated roof water is often better carried in solid pipe rather than released into the perforated collection trench. The best arrangement depends on capacity and the available outlet.
When is a good time to repair?
Dry weather makes excavation easier, but evidence immediately after rain can help identify where the system is failing.
