§ 9-508

This Chapter provides a method for reviewing Public Improvement Plans for on-site and off-site public improvements within County right-of-way or County-maintained areas that are required for conformance with Chapter 9-600, Infrastructure Standards: General Provisions, the County's Improvement Standards, and/or conditions of approval for discretionary applications.

When building of a dwelling is part of a subdivision or when required by a discretionary permit approval for any other construction associated with a subdivision or other development, a Public Improvement Plan for required on-site and off-site public improvements shall be prepared. The subdivider shall submit the plan after approval of a Tentative Map or tentative Parcel Map prior to the approval of the Final Map or Parcel Map.

Public Improvement Plans shall be prepared, stamped, and signed by a California-registered civil engineer. Off-site and on-site improvements required by the County's Improvement Standards and conditions of approval for the application shall be incorporated into the Public Improvement Plan as they apply to on-site and off-site public improvements. The plan shall depict lot lines and the location of buildings and driveways, hardscape and landscaping in the public right-of-way, utilities, parking layout when more than three cars will be parked on a lot, the circulation and drainage system within the subdivision, including any privately maintained streets and water and sewer and drainage systems, and other information required by the County's application form.

Public Improvement Plans shall be reviewed by the Department of Public Works. Such review shall include whether any proposed private streets conform to the County's public street design requirements. The Zoning Administrator in consultation with the Department of Public Works also may waive specific requirements and approve amendments.

Public Improvement Plans shall incorporate all of the information required by the conditions of approval of a Tentative Map or tentative Parcel Map and other requirements of this Title that relate to on-site and off-site public improvements to ensure that off-site and on-site infrastructure meets the minimum requirements of the County's Improvement Standards. Unless otherwise specified in this Title, no use can be established on a lot for which a Public Improvement Plan is required until all conditions of approval have been complied with and the Zoning Administrator determines that the Public Improvement Plan is acceptable and complete. Public Improvement Plans approved under this Title are approved for a period of 18 months from the date of approval.

(a)

Requirements Met. In those instances involving a use that requires the preparation of a Public Improvement Plan and a Public Improvement Plan has previously been approved, the Zoning Administrator may approve amendments to that Improvement Plan for the expansion or adjustment of an existing development if the expansion complies with all of the following requirements:

(1)

The existing Public Improvement Plan is adequate to determine the compliance of the proposed expansion with all required standards and conditions for on-site and off-site public improvements.

(2)

The building or use expansion is incidental to the existing use.

(3)

The building or use expansion does not result in a change of use.

(4)

The expansion does not involve an increase in facilities for truck parking

(5)

The building expansion involves less than 25 percent increase in floor area covered by the existing structures associated with the use.

(6)

A use involves less than ten percent increase in the overall site area covered by the existing use.

(7)

The building or use expansion complies with the existing requirements of the agencies having jurisdiction and any other appropriate agencies as determined by the Zoning Administrator.

(b)

Requirements Not Met. If the proposed expansion does not meet with all of the above requirements in paragraph (a), a new Public Improvement Plan shall be required.
