San Bernardino Floodplain and Wetland Development Rules

Land Use and Zoning California 3 Minutes Read · published February 10, 2026 Flag of California

San Bernardino, California regulates development in floodplains and wetlands through local planning, building, and environmental review to reduce flood risk and protect sensitive habitat. This guide explains where the rules live, which permits and approvals you may need, how enforcement works, and practical steps to apply, appeal, or report noncompliance. It summarizes municipal code provisions, federal FEMA procedures for floodplain determinations, and the City departments that administer permits and inspections. Use the official department contacts and code citations below when preparing applications or responding to enforcement actions.[1]

Overview of the Rules

Development in flood-prone areas and wetlands in San Bernardino is controlled by municipal zoning and development standards, stormwater and drainage requirements, and state and federal wetland protections where applicable. Projects typically require coordination with the City Planning Division and Building & Safety, and may need federal review or a Letter of Map Change from FEMA when base flood elevations or map statuses are in question.[2]

Penalties & Enforcement

The City enforces floodplain and wetland development rules through inspections, stop-work orders, administrative citations, and civil or criminal actions where authorized. Specific monetary fines and fee schedules for violations are referenced in the municipal code or enforcement ordinances; if a fine amount or escalation scheme is not published on the controlling page, the exact amount is not specified on the cited page and must be confirmed with the enforcing department.[3]

  • Enforcer: City of San Bernardino Planning Division and Building & Safety; Environmental review may involve other city or regional agencies.
  • Inspection pathways: routine plan review, site inspections, and complaints to Planning/Building.
  • Fines & fees: not specified on the cited page; consult municipal code or enforcement notices for amounts.
  • Escalation: first, repeat, and continuing offences may trigger increased penalties or abatement orders; exact escalation details are not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, mandatory remediation, permit revocation, and referral to civil court.
  • Complaints: submit through the City Planning or Building & Safety contact pages for investigation.
Failure to obtain required approvals can result in stop-work orders and remediation obligations.

Applications & Forms

Typical submissions for floodplain or wetland work include planning applications, grading permits, and building permits. Some projects may require environmental review under CEQA, and federal processes such as FEMA Letter of Map Amendment/Revision (LOMA/LOMR) for floodplain map updates. The City publishes application forms and filing instructions through Planning and Building & Safety; if a specific city form for floodplain permits is not listed on the cited pages, then no form is officially published there and applicants should contact the department directly.[1]

Many applicants in flood zones begin with a planning intake or pre-application meeting.

Common Violations and Typical Responses

  • Building without a permit in a mapped floodplain — may prompt stop-work order and required retroactive permits.
  • Failing to secure required environmental clearances for wetland impacts — may require mitigation or restoration.
  • Noncompliant grading or drainage that increases downstream flood risk — corrective grading and drainage plans often required.

How-To

  1. Identify whether your parcel is in a FEMA-mapped floodplain using FEMA tools or the City’s GIS.
  2. Request a pre-application meeting with City Planning to confirm which permits and studies are needed.
  3. Prepare required plans: site, grading, drainage, and any wetland delineation or biological assessment.
  4. Submit applications and fees to Planning and Building & Safety; respond to review comments and obtain permits before construction.
  5. If contested, file appeals as provided by municipal code and follow the listed time limits on the enforcement or appeals page.
Start with a pre-application meeting to avoid costly redesigns.

FAQ

Do I need a permit to build in a floodplain or wetland?
Yes. Development in mapped floodplains or regulated wetlands typically requires planning and building permits and may require additional environmental review.
How do I find out if my property is in a floodplain?
Check FEMA flood maps and contact City Planning for local GIS and confirmation; FEMA map inquiries can lead to LOMA/LOMR processes when applicable.[2]
What penalties apply for unpermitted work?
Penalties include stop-work orders, remediation requirements, administrative fines, and possible legal action; specific fine amounts are not specified on the cited municipal pages and must be confirmed with the enforcing department.[3]

Key Takeaways

  • Engage City Planning early—pre-application meetings save time and money.
  • Many projects require both city permits and federal actions like FEMA LOMA/LOMR.
