Thousand Oaks Municipal Code Art. 3 Control of Urban Runoff

(a) On and after September 1, 1999, all development activity within the City shall be undertaken in accordance with all of the following:

(1) The conditions and requirements established by the NPDES permit or other permit which are reasonably related to the reduction or elimination of pollutants in stormwater from the project site.

(2) A stormwater pollution prevention plan, which shall be prepared in accordance with state general permit requirements.

(3) A stormwater pollution control plan (if applicable), which shall be prepared in accordance with City requirements.

(4) Any condition and requirement of a stormwater quality master plan covering the development site. A stormwater quality master plan shall be required to be submitted by the property owner in accordance with the City’s requirements when the director determines that the development may result in the discharge of significant levels of any pollutant to the storm drain system, such as, but not limited to, the cases of specific plans, multi-phased subdivisions, redevelopment plans and larger planned developments.

(5) The conditions and/or requirements established by the City to protect specific watersheds or drainage basins.

(b) Prior to issuance by the City of any permit authorizing grading or construction for a development, the property owner of the site for such contemplated activity shall submit to and obtain the approval of the Director for a stormwater pollution control plan.

(c) Notwithstanding the foregoing, a stormwater pollution control plan shall not be required for construction by a property owner of only one single family detached residential unit, for a room addition to any existing residential unit, or for projects that require a grading permit and result in soil disturbance of less than one acre of surface area and which is not part of a larger common plan of development, unless the Director determines that the grading may result in the discharge of significant levels of a pollutant into the storm drain system. This exemption shall not apply to a phased project with construction of one home at a time but more than one dwelling unit is to be constructed over the full course of that residential project by any person.

(d) Each stormwater pollution control plan or stormwater quality master plan shall name a responsible party for the project and compliance with the plan.

(e) A City processing fee, in an amount determined by a City Council resolution, for its costs and expenses incurred in the review, approval, or revision of any stormwater pollution control plan and/or stormwater quality master plan shall be charged to the property owner or responsible party and shall be due and payable to the City at the time the plan is submitted to the City for review.

(f) Compliance with the conditions and requirements of a stormwater pollution control plan and/or stormwater quality master plan shall not exempt any person from the requirement to comply independently with each provision of this chapter.

(g) Proof of compliance with the state general permit for stormwater discharges associated with construction activity (NPDES Permit No. CAS000002) may be required in a form acceptable to the City prior to issuance by the City of any permit authorizing grading or construction; upon inspection of the construction site; during any enforcement proceeding or action; or for any other reasonable cause.

(§ 1, Ord. 1343-NS, eff. October 14, 1999)

(a) Any person engaged in any land use, activities or operations, or owning facilities or property, which may result in pollutants entering the storm drain system, as determined by the director, shall prepare, be subject to or obtain a best management practices manual and then implement those best management practices to the maximum extent practicable to prevent or reduce such discharge of pollutants to the City’s storm drain system or watercourses.

(b) The Director may adopt requirements identifying appropriate terms, obligations and minimum content of a best management practices manual (“BMPs”) for any land use, activity, business, operation, or facility which may cause or contribute the discharge of a pollutant to, or contamination of, the storm drain system. If relevant, certain BMPs have been prepared and promulgated by the City or any Federal, State, and/or regional agency for certain activities, operations, or facilities, which could cause the discharge of pollutants to the City’s storm drain system or watercourses, and every person undertaking such a designated activity or operation, or owning or operating such facility shall comply with such BMPs.

(§ 1, Ord. 1343-NS, eff. October 14, 1999)

Each responsible party, owner or discharger associated with any development or nonexempt construction activity, or any other discharger described in any NPDES or NPDES general permit as may be adopted by the EPA, the State Water Resources Control Board, or the Regional Water Quality Control Board, shall provide notice of intent, comply with, and undertake all other activities required by such permit applicable to such discharges.

(§ 1, Ord. 1343-NS, eff. October 14, 1999)

(a) After written notification is mailed, personally delivered or posted, the Director may require any person responsible for an illicit discharge to immediately, or by a specified date, eliminate or discontinue the illicit discharge, and the Director, if necessary as the result of an imminent or pending storm event, may take immediate measures to eliminate the source of the illicit discharge. If the discharge is not discontinued in the time specified, the Director may take any enforcement measure described in this chapter and steps reasonably necessary to eliminate the source of the illicit discharge or to prevent the reoccurrence of future illicit discharges.

(b) After written notification is mailed, personally delivered or posted, the Director may require a person in control of or responsible for an illicit connection to the storm drain system to secure approval for the connection by a specified date, regardless of whether or not the connection or discharges to it had been established or approved prior to the effective date of this chapter. If, subsequent to eliminating a connection found to be in violation of this chapter, the person can demonstrate that an illicit discharge will no longer occur, said person may request approval to reconnect. The reconnection or reinstallation of the connection shall be at the director's discretion and shall be subject to such conditions as the Director may determine; such reconnection or reinstallation shall be at the requesting person’s sole expense.
