16.04.020 Purpose.

It is the purpose of this title to regulate and control the division of land within the city and to supplement the provisions of the state Subdivision Map Act concerning the design, improvement and survey data of subdivisions, the form and content of all maps provided for by the state Subdivision Map Act and the procedure to be followed in securing the official approval of the city regarding such maps. To accomplish this purpose, the regulations outlined in this title are determined to be those reasonably necessary for the preservation of the public health, safety, and general welfare, to promote orderly growth, development, open space, conservation, protection and proper use of land, and to ensure provision for adequate traffic circulation, utilities and services. (Prior code § 25.2)

Exceptions & meaning →

C. The city may not approve a subdivision of land unless the subdivider establishes that the subdivision and construction of improvements will be appropriately timed and phased such that the development will be supported by adequate facilities and services, and such that appropriate measures can be taken to mitigate adverse environmental impacts. Adequacy of facilities and services shall be determined in accord with: (1) the planned long-term build-out of the community as provided in capital improvements programs in which facilities are actually available or funded; and (2) the general plan elements in effect at the time of considering the application. (Prior code § 25.3)

16.04.070 Waiver or modification of requirements.

A. The city council may waive or modify any of the requirements and regulations set forth in this title. Application for any such waivers or modifications shall be made in writing by the subdivider, stating fully the grounds of the application and the facts relied upon by the subdivider. Such application shall be filed with the tentative or tentative parcel map application. In order for the property referred to in the application to come within the provisions of this section, the city council shall find that the granting of the modification will not be detrimental to the public welfare or injurious to other property in the territory in which the property is situated, and that:

  2. The waiver or modification will improve the overall subdivision design; or

  3. The property is to be devoted to such use that it is impossible or impracticable in the particular case for the subdivider to comply fully.

C. The city council or planning commission shall specifically and fully set forth the modification and the conditions designated.

A. A violation of this title is a public nuisance.

B. The city shall not issue a permit or grant any approval necessary to develop any real property which has been divided, or which has resulted from a division, in violation of the provisions of the state Subdivision Map Act or this title if it finds that development of such real property is contrary to the public health or the public safety. The authority to deny such a permit or approval shall apply whether the applicant therefor was the owner of record at the time of such violation or whether the applicant therefor is either the current owner of record or a vendee thereof with, or without, actual or constructive knowledge of the violation at the time of the acquisition of an interest in such real property.

C. If the city issues a permit or grants approval for the development of any real property illegally subdivided, the city may impose those additional conditions which would have been applicable to the division of the property at the time the current owner of record acquired the property. If the property has the same owner of record as at the time of the initial violation, the city may impose conditions applicable to a current division of the property. If a conditional certificate of compliance has been filed for record in accordance with the provisions of Section 16.04.170, only those conditions stipulated in that certificate shall be applicable. (Prior code § 25.162)

Exceptions & meaning →

16.04.170 Certificate of compliance.

A. Any owner of real property or a vendee of such person pursuant to a contract of sale of such real property, may request in writing, that the planning director make a determination whether such real property does or does not comply with the provisions of the state Subdivision Map Act and this chapter. The property owner or vendee shall be entitled to present any facts or documents to the planning director. If a determination of compliance is made the planning director shall cause a certificate of compliance to be filed with the county recorder.

B. If the planning director determines that such real property does not comply with the provisions of this title or state Subdivision Map Act, or wishes to refer the decision to the planning commission, the planning director shall set the issue for hearing before the planning commission.

  1. If a determination of compliance is made by the planning commission, the planning director shall cause a certificate of compliance to be filed with the county recorder.

  2. If the planning commission determines that such real property does not comply with this title or the state Subdivision Map Act, the planning commission shall issue a conditional certificate of compliance. The planning commission may, as a condition to granting a conditional certificate of compliance, impose conditions in accordance with Section 16.04.160(C). Upon the planning commission making such a determination and establishing such conditions, the planning director shall issue a conditional certificate of compliance which shall be filed with the county recorder. Such certificate shall serve as notice to the property owner or vendee who has applied for the certificate pursuant to this section, a grantee of the property owner, or any subsequent transferee or assignee of the property that fulfillment and implementation of the conditions set forth in the certificate shall be required prior to the subsequent issuance of a permit or other grant or approval for the development of the property. Compliance with such conditions shall not be required until such time as a permit or other grant of approval for development of such property is issued by the city.

C. A final map or parcel map filed for record shall constitute a certificate of compliance with respect to the lots created therein. (Ord. 02-1 § 16; prior code § 25.163)

Exceptions & meaning →

16.04.180 Notice of violation.

If the planning department has knowledge that real property has been divided in violation of the provisions of the state Subdivision Map Act or this title, a notice of intention to record a notice of violation shall be mailed by the department by certified mail to the current owner of record. The notice shall describe the property in detail, name the owners, describe the violation and state that the owner will be given the opportunity to present evidence. The notice shall also contain an explanation as to why the subject parcel is not lawful under Section 66412.6 (a) and (b) of the state Subdivision Map Act. The notice shall specify the date, time and place for a meeting at which the owner may present evidence to the planning director and city attorney why a notice of violation should not be recorded.

The meeting shall be held no sooner than thirty (30) days and no later than sixty (60) days from the date of mailing of the notice of intention to record a notice of violation. If, within fifteen (15) days of receipt of the notice, the owner fails to file with the department a written objection to recording the notice of violation, the department shall file the notice of violation for record with the county recorder. If, after the owner has presented evidence, staff determines that there has been no violation, the department shall mail a clearance letter to the then current owner of record. If, however, after the owner has presented evidence, staff determines that the property has in fact been illegally divided, the department shall record the notice of violation for record with the county recorder. The notice of violation, when recorded, shall be deemed to be constructive notice of the violation to all successors in interest in such property. (Prior code § 25.164)

Exceptions & meaning →
