The District, Public Works and the Right-of-Way Trigger
The Los Angeles County Flood Control District was created under the Flood Control Act the State Legislature adopted in 1915, and its operations transferred to LA County Public Works in 1984. Public Works' Land Development Division issues the District's permits. Its 2013 permit guidance brochure described a system of 15 major dams, 162 debris basins, 530 miles of open channels, 2,800 miles of underground storm drains and more than 78,000 catch basins; those figures come from a 2013 document and may have changed.
The permit trigger is broad. Public Works states that any work, encroachment or activity within or affecting the District's right of way requires a Flood Control Permit. A storm drain connection from a new development, a utility crossing under a channel, landscaping on a channel bank or a staging area on District land can each fall inside that language, so a developer or civil contractor working beside a channel or basin typically asks early whether a District permit applies.
City and county rules elsewhere in the region are covered under Los Angeles construction insurance and agency rules.
Flood Construction and Flood Access Permit Types
The District sorts its permits into two families, and applications go through the County's EPIC-LA system. Construction permits, in the words of the District's guidance brochure, allow encroachment onto or alteration of District right of way for new construction. Access permits cover discharges, temporary use and access and film scouting.
The Excavation and Temporary Use and Access permit pages list the submittals. Applicants need a contractor license number and insurance, sealed plans that show the District's right of way, a letter of authorization when the property owner is not the applicant and a plan check fee invoiced in EPIC-LA. Encroachment permits for city streets, county roads and state highways are separate processes with their own security.
- Flood Construction: Bridging, Catch Basin Relocation and Retrofit, Connection, Crossing, Encroachment, Excavation, Landscaping, Modification, Overbuild and Transfer Drain
- Flood Access: Annual Discharge, Annual Temporary Use and Access, Discharge, Temporary Use and Access and Express Flood Film Scouting
Caltrans and city street-work permit security is explained in California encroachment permit bonds.
Review Time, Agreements and Federal Facilities
The 2013 guidance brochure said simple access and filming permits took about two weeks, while engineering permits could take several reviews of four to six weeks each. Those estimates are dated and are not a promise of current timing, but they show why a connection or bridging permit belongs on the critical path rather than in the last month before construction.
The brochure also notes that the District may require a use or maintenance agreement, and that facilities the federal government built need U.S. Army Corps of Engineers approval under Section 408. An agreement of that kind can carry its own insurance, indemnity or maintenance terms, so the contractor and the owner typically read it alongside the permit before deciding who holds each obligation.

Insurance Limits on the Permit Insurance Sheet
The insurance requirements sheet linked from the District's Flood Control Permit References page carries a footer revision date of October 25, 2016. It speaks of the Agency and the Permit in general terms, and it is the sheet the District links for flood permits. The general liability limits it lists are below, and it treats a $2,000,000 combined single limit policy with aggregate limits as equivalent.
For workers' compensation, the sheet asks for employer's liability of at least $1,000,000 per accident from an insurer rated at or above the State Compensation Insurance Fund. Auto liability is $1,000,000 per accident for owned, leased, hired and non-owned vehicles. The policies need a waiver of subrogation and 30 days' mailed notice of cancellation or expiration. One insurance filing may support more than one permit, and the sample shows policies staying valid until after the permit expires, so renewal dates matter on long permits.
- General aggregate: $2,000,000
- Other than products and completed operations aggregate: $2,000,000
- Products and completed operations aggregate: $2,000,000
- Personal injury: $1,000,000
- Each occurrence: $1,000,000
How utility and civil contractors build limits for agency permits is covered under civil and underground utility contractor insurance.
The Additional Insured Wording the County Expects
The sheet states that the Agency shall be named as an additional insured covering the work, whether liability is attributable to the Permittee or the Agency. It also gives required wording for the additional insured: "The County of Los Angeles and public entity or Special District for which the Los Angeles County Board of Supervisors is the Governing Body." The certificate holder is the County of Los Angeles Department of Public Works, Land Development Division, PO Box 1460, Alhambra.
Many contractors carry a blanket additional insured endorsement keyed to a written contract or to the contractor's own negligence. Whether that endorsement matches the County's wording, and whether it responds where liability is attributed to the Agency, depends on the endorsement form and the facts. Comparing the endorsement to the sheet before the permit is filed typically avoids a returned application.
Standard Provisions: Indemnity, Repairs and Revocation
The Standard Flood Control Permit Provisions, footer-dated February 5, 2018, attach to District permits. The permittee, including its contractors and subcontractors, must indemnify and defend the District and the County, with counsel reasonably satisfactory to both, and hold them harmless. The provisions state that this obligation shall remain in full force and effect in perpetuity, unless the District agrees otherwise in writing.
The permittee repairs any damage to District structures at its sole cost and must remove or relocate its improvements at no cost to the District if District needs require it. The permit is revocable at any time for District purposes, with restoration on revocation. Storage in the right of way is not allowed, and fines from the Water Board, the California Department of Fish and Wildlife or the U.S. Coast Guard for pollution, along with all other costs, fall on the permittee.

Fiscal Year 2026-27 Permit Fees
The District's fee schedule, with CPI adjustments under Chapter 17.05, lists revised fees effective July 1, 2026. Permit issuance applies to every permit type, and plan check and inspection charges depend on the work. Excavation and major bridging work are billed at actual cost above the minimums shown.
- Permit issuance, all types: $180
- Plan check, connections: $235 for 1 to 6 inches, $462 for 8 to 12 inches and $1,144 for over 12 to 24 inches
- Plan check, excavations: actual cost, $1,500 minimum
- Inspection: bridging clear span $2,283; major bridging actual cost, $1,800 minimum; excavations actual cost, $1,000 minimum
- Temporary use of right of way: $115 per day rental
- Permit extension: $125
Bonds and Deposits: Confirm with Public Works
No permit bond or security deposit appears in the Standard Flood Control Permit Provisions, the permit pages or the fee schedule read for this page. That does not settle whether Public Works asks for security on a particular permit, so security, if any, is confirmed with LA County Public Works before the contractor prices the job or asks its surety for capacity. A use or maintenance agreement, where the District requires one, is another place such terms could appear.
This page covers the District's permits only. Capital construction contracts that Public Works lets for District facilities carry their own bid, bond and insurance terms in each contract's documents, and those are outside this page. Any permit security or insurance placement is subject to Public Works, the surety and underwriting, and policy terms vary with carrier guidelines and programs.

Before You Ask for a Quote

What to Ask the Insurer or Surety
- Which permit type fits the work: connection, crossing, excavation, encroachment or temporary use?
- Does Public Works require a bond or deposit for this permit, and in what form?
- Can one insurance filing support all of our open District permits?

- Do our policy terms run past the permit expiration date, as the sample certificate expects?
Quick Answer
Work within or affecting Los Angeles County Flood Control District right of way needs a Flood Control Permit, with liability limits of $1,000,000 each occurrence and $2,000,000 aggregates, required additional insured wording and an indemnity that remains in effect in perpetuity.
Common Mistake
Assuming a standard blanket additional insured endorsement matches the County's insurance sheet. The sheet names the County and the special districts the Board of Supervisors governs, so the endorsement is compared before the permit is filed.
Broker Perspective
Because the provisions keep the indemnity in force in perpetuity, the completed operations terms and the contractual liability coverage in the contractor's policies matter long after the permit closes.
Coverage Impact
Whether a liability policy responds to the perpetual indemnity depends on its contractual liability terms, the additional insured endorsement and the facts of a claim, and regulatory fines raise separate questions.
