Sec. 9-1-50. - New development and significant redevelopment.

(a) All new development and significant redevelopment within the unincorporated area of the County shall be undertaken in accordance with the DAMP, including but not limited to the development project guidance.

(b) Prior to the issuance by the County of a grading permit, building permit or nonresidential plumbing permit for any new development or significant redevelopment, OC Public Works shall review the project plans and impose terms, conditions and requirements on the project in accordance with Section 9-1-50(a). If the new development or significant redevelopment will be approved without application for a grading permit, building permit or nonresidential plumbing permit, OC Public Works shall review the project plans and impose terms, conditions and requirement on the project in accordance with Section 9-1-50(a) prior to the issuance of a discretionary land use approval or, at the County's discretion, prior to recordation of a subdivision map.

(c) Notwithstanding the foregoing Sections 9-1-50(a) and (b), compliance with the development project guidance shall not be required for construction of:

(1) A (one) single family detached residence; or

(2) Improvements, for which a building permit is required, to a (one) single-family detached residence unless OC Public Works determines that the construction may result in the discharge of significant levels of a pollutant into a tributary to the stormwater drainage system.

(d) Compliance with the conditions and requirements of the DAMP shall not exempt any person from the requirement to independently comply with each provision of this division.

(e) If OC Public Works determines that the project will have a de minimis impact on the quality of stormwater runoff, then it may issue a written waiver of the requirement for compliance with the provisions of the development project guidance.

(f) The owner of a new development or significant redevelopment project, or upon transfer of the property, its successors and assigns, shall implement and adhere to the terms, conditions and requirements imposed pursuant to Section 9-1-50(a) on a new development or significant redevelopment project.

Each failure by the owner of the property, or its successors or assigns, to implement and adhere to the terms, conditions and requirements imposed pursuant to Section 9-1-50(a) on a new development or significant redevelopment project shall constitute a violation of this division.

(g) OC Public Works may require that the terms, conditions and requirements imposed pursuant to Section 9-1-50(a) be recorded with the county recorder's office by the property owner. The signature of the owner of the property or any successive owner shall be sufficient for the recording of these terms, conditions and requirements and a signature on behalf of the County of Orange shall not be required for recordation.
