Fresno Brownfield Soil Testing & Cleanup Guide

Environmental Protection California 4 Minutes Read ยท published February 08, 2026 Flag of California

Fresno, California property owners and developers facing potential brownfield sites must follow municipal and county procedures for soil testing, reporting, and remedial action. This guide summarizes the typical steps, responsible offices, enforcement pathways, and how to move from site assessment to closure under Fresno-area practice and California oversight. It highlights who to contact, common permits, and where to submit reports.

Preliminary Assessment & When to Test

Begin with a site history review and a Phase I environmental site assessment to identify likely sources of contamination such as former industrial uses, underground storage tanks, or historic disposal areas. If the Phase I indicates potential contamination, a Phase II with soil sampling and laboratory analysis is the usual next step.

Order a Phase I when the site has industrial, fueling, or long-term storage history.

Regulatory Roles and Authorities

  • City of Fresno planning, building, and environmental divisions handle local permits and land-use restrictions; site-specific remediation oversight may involve city review and conditioning of permits[1].
  • Fresno County Environmental Health enforces public health protections for soil and groundwater and may require investigation or corrective action where county jurisdiction applies[2].
  • State oversight for site cleanup and closure commonly involves the California State Water Resources Control Board and the Department of Toxic Substances Control for hazardous substances and long-term remediation[3].

Sampling, Reporting, and Cleanup Steps

  1. Phase I ESA: historical records, interviews, and site reconnaissance.
  2. Phase II sampling plan: soil, soil gas, and groundwater as appropriate; follow EPA or state guidance for sampling methods.
  3. Laboratory analysis and a technical report documenting methods, results, and comparison to applicable screening levels.
  4. Remedial action: excavation, removal, in-place treatment, or engineered controls based on risk and regulatory direction.
  5. Site closure or case closure documentation submitted to the overseeing agency for verification.

Penalties & Enforcement

Enforcement for improper handling, failure to report, or unauthorized disturbance of contaminated soil in Fresno-area sites may be carried out by city, county, or state agencies depending on jurisdiction. Specific fine amounts and escalation criteria are not always listed on municipal pages and may be in enforcement orders or state statutes.

  • Monetary fines: not specified on the cited page[1].
  • Escalation: first, repeat, and continuing offences and per-day penalties are not specified on the cited page; check enforcing agency orders or state code for amounts[3].
  • Non-monetary sanctions: stop-work orders, cleanup orders, administrative orders, liens on property, and court enforcement are routinely used by county or state agencies; specific remedies are set in enforcement instruments and not fully specified on the cited pages[2].
  • Enforcer and complaint pathway: contact City of Fresno planning or building divisions, Fresno County Environmental Health, or the State Water Resources Control Board depending on the situation[1].
  • Appeals and review: appeals typically follow administrative order procedures; specific time limits for appeal are not specified on the cited municipal pages and should be confirmed with the issuing agency[1].

Applications & Forms

The exact permit or form depends on the site and remedy. Municipal planning or building permit applications, a soil management plan, and submittal of technical reports are commonly required. A single, universal city brownfield form is not specified on the cited city page[1].

Contact the issuing agency early to confirm which forms and fees apply.

Common Violations

  • Failure to conduct required sampling before redevelopment.
  • Unauthorized excavation or off-site disposal of known contaminated soil.
  • Failing to submit required technical reports or notifications to oversight agencies.

FAQ

Who do I notify if I find suspect contamination?
Notify Fresno County Environmental Health for health risks and City of Fresno planning or building divisions if redevelopment is planned; state agencies may need notice for hazardous releases.
Do I need a permit to remove contaminated soil?
Permits or approvals are often required; confirm with City of Fresno planning/building and Fresno County Environmental Health before removal.
How long does closure take?
Time to closure varies with the complexity of contamination, remedial method, and regulatory review; specific timelines are case-dependent.

How-To

  1. Step 1: Order a Phase I ESA to screen historical risks.
  2. Step 2: If flagged, prepare a Phase II sampling plan and coordinate with county or city contacts.
  3. Step 3: Conduct sampling, submit lab results, and prepare a technical report.
  4. Step 4: Propose remedial actions and obtain required permits or approvals.
  5. Step 5: Implement remediation, document completion, and seek case closure from the overseeing agency.

Key Takeaways

  • Start with a Phase I ESA to define risk and next steps.
  • Coordinate early with City of Fresno and Fresno County Environmental Health to avoid enforcement delays.
  • Keep thorough records: sampling plans, chain-of-custody, and technical reports aid closure.
