Coastal Development: El Monte vs Santa Clarita

Do I need a Coastal Development Permit for my El Monte project?

No. El Monte is in the inland San Gabriel Valley and is entirely outside the California Coastal Zone as defined in Public Resources Code Section 30103. The Coastal Act does not apply, and the Coastal Commission has no jurisdiction over development in El Monte.

Why does this category appear if El Monte is not coastal?

For completeness. The San Gabriel River that runs through El Monte drains to the Pacific Ocean at Long Beach, so water-quality rules from the LA Regional Water Quality Control Board (MS4 Permit Order R4-2021-0105) still apply - but those are addressed in El Monte's Stormwater Ordinance (EMMC Chapter 13.16), not under the Coastal Act.

What if I am building on a parcel adjacent to the San Gabriel River?

Coastal Act rules still do not apply. Your project is governed by the LA County Flood Control District encroachment rules, El Monte's FEMA floodplain provisions, and EMMC Chapters 13.16/13.20 (stormwater and LID). Contact El Monte Public Works for setback and BMP requirements.

Do I need a coastal permit?

Most development within the coastal zone requires permits from both Santa Clarita and the state coastal commission. Check if your property is in the designated coastal zone.

Can I build a seawall on my property?

Seawalls and shoreline armoring face strict review and may be denied if alternatives exist. Living shoreline approaches are increasingly preferred.
