Exceptions & meaning →

Sec. 6-8-303. - Control of stormwater/urban runoff.

A. Priority project development/redevelopment.

  1. A water quality management plan (WQMP) is required if a project is a priority project, or if approval of the project requires discretionary action involving approval of a precise plan, or if the project involves a non-residential plumbing permit for work with the potential to impact water quality. All new development and significant redevelopment projects within the City of Irvine, including, but not limited to, those considered to be priority development projects, shall be undertaken in accordance with:

a. A WQMP prepared in accordance with the drainage area management plan (DAMP) and the City's local implementation plan; and

b. Any conditions and requirements established by the Community Development Department of the City, which are reasonably related to the reduction or elimination of pollutants in runoff from the project site.

  1. The City shall require project applicants to submit a WQMP at one or both of the following points in the project planning and permitting process:

a. During the discretionary approval process (land use permit) of a proposed project, when the City must exercise judgment or deliberation in order to approve or disapprove a new development or significant redevelopment project; or

b. During the ministerial approval process of issuing a grading, building, demolition, or similar "construction" permits in which only fixed standards or objective measures are applied.

WQMPs submitted during the discretionary approval process may be conceptual or preliminary with final WQMPs submitted during the ministerial permit process. Projects subject to the regional program (described in Section A-7 of the City's local implementation plan) may rely upon the regional plan at the discretionary process.

Conceptual (Preliminary) WQMPs submitted during the discretionary approval process and/or before the ministerial approval process may be programmatic or planning level documents that will guide the coordinated selection, deployment and, as required, construction of appropriate project-specific, precise water quality control measures and best management practices (BMPs) throughout a development area. Such a conceptual or preliminary WQMP shall address the entire development area and provide preliminary details on source control BMPs and LID/treatment control BMPs.

Final (Project Specific) WQMPs submitted during the ministerial approval process shall include final details for all source control and LID/treatment control BMPs, including final design specifications for all structural BMPs, within the area addressed by the ministerial permit. The content of a Final (Project Specific) WQMP must be substantially consistent with the Conceptual (Preliminary) WQMP.

  1. Compliance with the conditions and requirements of any WQMP shall not exempt any person from the requirement to independently comply with each provision of this chapter.

  2. The WQMP shall require Low Impact Development (LID) BMPs to address the design capture volume as detailed in the City's local implementation plan and the DAMP.

  3. The WQMP shall evaluate and address hydrologic conditions of concern based on two-year frequency storm event as detailed in the City's local implementation plan and DAMP.

  4. The above requirements in Subsections 6-8-303A.4 and 6-8-303A.5 for Low Impact Development BMPs and hydrologic conditions of concern are not applicable to projects that have a WQMP approved by the City within 90 days from date of approval of the revised model WQMP (as provided for under the NPDES permit).

  5. Each WQMP shall name a responsible party for the project.

  6. The owner of the property of the new development or significant redevelopment project, their successors and assigns, and each named responsible party, shall be responsible for the implementation and adherence to the terms, conditions and requirements of the approved WQMP. Each failure by the owner of the property, their successors or assigns, or a named responsible party, to implement and adhere to the terms, conditions and requirements of an approved WQMP shall constitute a separate violation of this chapter.

  7. The City's Community Development Department, Building and Safety Division, may require that the WQMP be recorded with the County Recorder's Office by the property owner. If such a recorded document is required by the City, the signature of the owner of the property, any successive owner or the named responsible party shall be sufficient for the recording of the plan or any revised plan, and a signature on behalf of the City shall not be required for recordation.

B. Non-priority project development/redevelopment. A non-priority project water quality plan is required to be completed for new development and significant redevelopment projects that qualify as non-priority projects. These are projects that do not fall under one of the priority development project categories but meet one of the following conditions:

  1. Requires discretionary action that will include a precise plan of development;

  2. Requires issuance of a non-residential plumbing permit for pipelines conveying hazardous materials (e.g. gasoline); or

  3. A public works project that requires replacement of more than 5,000 square feet of impervious surface due to below ground linear drainage, and/or utility construction projects which maintain original finish surface line and grade, hydraulic capacity, original purpose of the facility, or occur in response to an emergency to protect public health and safety.

C. Cost recovery. The costs and expenses of the City incurred in the review, approval, or revision of any WQMP shall be assessed to the property owner or responsible party and shall be due and payable to the City. The City may elect to require a deposit of estimated costs and expenses, and the actual costs and expenses shall be deducted from the deposit, and the balance, if any, refunded to the property owner or responsible party.

D. Litter control. No person shall discard any waste material, including, but not limited to, common household rubbish or garbage of any kind (whether generated or accumulated at a residence, business or other location), upon any public or private property, whether occupied, open or vacant, including, but not limited to, any street, sidewalk, alley, right-of-way, open area or point of entry to the stormwater drainage system. Every person occupying or having charge and control of private property on which a prohibited disposal of waste materials occurs shall cause the proper collection and disposal of same.

A prohibited disposal of waste materials creates a danger to public health, safety and welfare, and otherwise threatens the environment, surface waters and groundwater; therefore, any owner or occupant of private property who fails to remove waste material within a reasonable time may be charged with creating a nuisance upon the property and the nuisance may be abated in accordance with Section 6-8-305B et seq., of this chapter.

E. Inspections of construction sites. As a condition to any construction or grading permit that may be issued within the City, and in order to ensure compliance with the terms of this chapter and any applicable permit or license for runoff or the discharge of any "waste" (as such term is defined in the California Water Code § 13050) and further, as may be necessary to ensure compliance with any WQMP or condition of any building or grading permit, the City may conduct inspections as necessary to ensure compliance with all such requirements.

F. Building, construction and grading permits. Prior to the issuance of any building, construction, or grading permit, the Authorized Inspector may require, as a condition to any such permit, the implementation of appropriate BMPs to ensure that the discharge of pollutants from any such site will be reduced to the maximum extent practicable and will not cause or contribute to an exceedance of water quality standards. BMP selection and implementation shall be in accordance with the City's local implementation plan, and shall be incorporated into the project plans and specifications to the satisfaction of the Authorized Inspector. All construction and grading activities shall comply with applicable laws, including all applicable State issued NPDES permits, the terms of this chapter, all applicable City codes, and the applicable requirements of the NPDES permit.
