El Niño Asphalt Protection & Repair in Pasadena
Getting Pasadena pavement ready for El Niño storms, and repairing asphalt, seal coat and striping after storm damage. GSEC serves HOA communities, commercial properties and public agencies across Los Angeles County.
Lots near the San Gabriel foothills see runoff carrying gravel and debris downhill, which clogs drains and scours pavement edges. El Niño winters can bring stronger and more frequent storms to Southern California, and the biggest risk to asphalt is water getting through the surface into the base. Once the base is soft, traffic breaks the pavement apart and potholes form.
For Pasadena properties, the main local concern is debris-heavy runoff from nearby foothills.
Before the storms: protect asphalt
Walk the lot and map cracks, soft spots and areas that held water last winter.
Clean and seal cracks so water stays out of the base.
Patch failing sections and potholes before they get larger.
Clear gravel and leaf debris from drains and gutters, and protect pavement edges where runoff from the foothills enters the lot.
Seal coat before El Niño
Seal coat aged, oxidized asphalt to help shed water.
Apply only in dry weather with enough cure time before rain.
Repair cracks and patches first so the seal coat protects a sound surface.
Striping before the rainy season
Refresh faded stripes, fire lanes and ADA markings so they stay visible in rain and low light.
Re-stripe after any seal coating.
Check that crosswalks and stop bars are clear for wet-weather traffic.
After the storms: repair asphalt
Inspect for potholes, alligator cracking, raveling and edge washouts.
We remove sediment left by runoff, check edges for scour and repair any areas where the base washed out.
Repair potholes and failed areas with properly compacted hot mix asphalt.
Remove and replace sections where the base has failed.
Seal coat repair after storm damage
Clean off silt, debris and oil washed onto the surface.
Patch and crack-seal first, then reseal worn or stripped areas.
Wait for dry, mild weather so the seal coat bonds and cures correctly.
Striping repair after El Niño
Re-stripe areas worn by water, sediment and patching.
Restore ADA stalls, fire lanes and directional arrows.
Lay out new striping after any repaving or reseal.
Drainage checklist for Pasadena property managers
Clear catch basins, trench drains and gutters before each forecast storm.
Note where water ponds during the first rain and schedule repairs for those spots.
Keep heavy trucks off soft or saturated areas when possible.
Mark potholes and hazards right away to protect drivers and pedestrians.
Call for an inspection after major storms so small damage is fixed before it spreads.
