El Niño Asphalt Protection & Repair in Los Angeles
Getting Los Angeles 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.
Dense commercial corridors, large multifamily parking structures and hillside neighborhoods mean storm runoff moves fast and collects at low drive aisles and alley entrances. 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 Los Angeles properties, the main local concern is fast urban runoff and ponding in flat lots.
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 every catch basin and alley drain, and correct low drive aisles where runoff from surrounding buildings collects.
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 look for undercut edges near drains and alleys and for alligator cracking in drive aisles that held water.
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 Los Angeles 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.
