No Fee Access Permit Application
What is an Encroachment Permit?
An encroachment permit is required whenever work is proposed within the public rights-of-way or easement. Typical examples of work include:
Encroachment Permit Requirements
- Trenching across public right-of-way for installation of water, sewer, storm drain, cable, and other underground utilities
- Construction of curb, gutter, sidewalk, driveway, and roadway pavement
- Water monitoring and extraction wells, soil sample borings
Application for Encroachment Permit
and submit it to the Flood Control District office. Read the list below to find out what else is required.
. Completed and signed Application Form
. A check or money order written for the appropriate fee amount to be deposited. (Please refer to the attached Encroachment Permit Fee Deposit Requirement Sheet.) Fees will be placed in an individual account and all District costs will be tracked as work is performed. If the balance in the account drops under 25% of the original deposit and the General Manager-Chief Engineer determines that the remaining amount is insufficient to complete the processing of the application (including environmental review, inspection and finalization of the project), the applicant will be required to submit an additional deposit prior to continuing to work on the application or proceeding with any further work on the project. Further inspections will not be scheduled until the additional deposit is submitted. Once a project is completed and accepted by the District, all unused funds will be refunded to the applicant within 60 days. All applicants, including public entities, must submit the required fee.
. Two (2) sets of 90% plans for the proposed work.
. Two (2) copies of the District as-built drawing(s) clearly showing the proposed work to be done under the requested encroachment permit. As-built drawings can be purchased from the District's Reproduction Section (951.955.1221).
. A copy of the approved and filed California Environmental Quality Act (CEQA) document (e.g., Notice of Exemption, Negative Declaration, Mitigated Negative Declaration/Initial Study, Environmental Impact Report and Statement of Overriding Consideration) as prepared by the Lead Agency for the proposed project shall be submitted to the District. The CEQA document is usually available from the City or County Planning Department that originally approved the proposed project. The District, as a CEQA Responsible Agency, must prepare the appropriate CEQA document for the proposed project prior to issuance of the requested encroachment permit.
. Proof of prior compliance with the approved Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) must be submitted to the District for proposed projects with the boundaries of the MSHCP. For projects previously approved by the County or Cities, this proof may consist of written documentation from the applicable jurisdiction confirming compliance with the MSHCP. Documentation concerning payment of the MSHCP Mitigation Fee alone is not sufficient. The District must receive written documentation specifically confirming compliance with Sections 6.1.2, 6.1.3, 6.1.4 and 6.3 of the MSHCP as well as the Criteria if the project is located within the Criteria Area/Cell. Encroachment Permits associated with a project not previously reviewed by the County or a City for MSHCP compliance or Encroachment Permits not associated with any project that are located within the boundaries of the MSHCP will need to be reviewed for compliance with the requirements of the MSHCP by the District prior to issuance of the requested Encroachment Permit. The issuance of an Encroachment Permit by the District is a discretionary action subject to compliance with the MSHCP.
. NPDES REQUIREMENTS: Encroachment permit applicants whose projects will disturb greater than one acre must demonstrate coverage under California’s Construction General Permit and submit a Storm Water Pollution Prevention Plan (SWPPP), per requirements of the State Water Resources Control Board. A copy of the SWPPP shall be provided and approved by the District prior to receiving the requested encroachment permit. A SWPPP template and guidance on the preparation of a SWPPP can be purchased and/or downloaded from the California Association of Stormwater Quality Agencies (CASQA) website at:
If the project will disturb less than one acre and/or does not require a SWPPP, a Water Pollution Control Program (WPCP) must be submitted to the District for approval; the WPCP template can be found at:
Additionally, encroachment permit applications associated with new or redevelopment projects proposing to discharge stormwater or non-stormwater into District facilities must identify the structural and non-structural post-construction best management practices (BMPs) that will be utilized to mitigate water quality and hydrologic impacts from the proposed project.
a. ENCROACHMENT PERMITS WITHIN THE SANTA ANA WATERSHED: Projects within the Santa Ana watershed regions of Riverside County must meet the requirements of Section 6 of the Riverside County Drainage Area Management Plan for the Santa Ana watershed Region (SA DAMP). Encroachment permit applications for projects that meet the definition of New Development or Significant Redevelopment per Section 6 of the SA DAMP may demonstrate compliance by providing proof of completion of a project-specific Water Quality Management Plan (WQMP). Projects that do not meet the definition of New Development or Significant Redevelopment per Section 6 of the SA DAMP must demonstrate compliance with the Structural and Operational BMP requirements specified for other development projects in Section 6.5.4 of the SA DAMP. Submittal of plans identifying the locations of post-construction BMPs can be used to demonstrate compliance with this requirement.
b. ENCROACHMENT PERMITS WITHIN THE SANTA MARGARITA WATERSHED: Projects within the Santa Margarita watershed region of Riverside County must meet the requirements of Section 6 of the District’s Jurisdictional Runoff Management Plan (District JRMP). Encroachment permit applications for projects that meet the definition of a Priority Development Project per Section 6 of the District JRMP may demonstrate compliance by providing proof of completion of a project-specific Water Quality Management Plan (WQMP). Projects that do not meet the definition of Priority Development Project per Section 6 of the District JRMP must demonstrate compliance with the Low Impact Design (LID) and Source Control BMP requirements specified for Other Development Projects in Section 6.6.6 of the District’s JRMP. Submittal of plans identifying the locations of post-construction BMPs can be used to demonstrate compliance with this requirement.
c. ENCROACHMENT PERMITS WITHIN THE WHITEWATER WATERSHED: Projects within the Whitewater Watershed Region of Riverside County must meet the requirements of Section 4 of the Whitewater Region Storm Water Management Plan (WW SWMP). Encroachment permit applications for projects that meet the definition of new development or redevelopment per Section 4.1 of the WW SWMP may demonstrate compliance by providing proof of completion of a project-specific Water Quality Management Plan (WQMP). Projects that do not meet the definition of new development or redevelopment per Section 4 of the WW SWMP must demonstrate compliance with the structural and non-structural BMPs requirements specified for other development projects per the requirements of Section 4.2.1 of the WW SWMP; submittal of plans identifying the locations of post-construction BMPs can be used to demonstrate compliance with this requirement.
d. Encroachment permit applicants not associated with new or redevelopment projects who discharge stormwater or non-stormwater to District facilities must identify the necessary structural and non-structural BMPs to mitigate water quality and/or hydrologic impacts from the proposed project, and if applicable, demonstrate compliance and/or coverage under an NPDES permit which may be applicable to the discharge.
