A preliminary map, in addition to a tentative and final map, shall be required for all subdivisions creating 10 or more lots, or in the case of condominium and conversion projects 10 or more units, except for those subdivisions described in SMC 16.12.060.
16.12.020 Lot line adjustment map.¶
A. A lot line adjustment map may be submitted and approved for a boundary adjustment which does not create a greater number of lots than originally existed if each of the proposed lots meets all the requirements of local building and zoning ordinances, this code, and the General Plan.
B. Applicants for a lot line adjustment approval shall submit to the Planning Department a completed application form signed by all parties having a record title interest in the involved property along with the following:
Copies of the recorded document that established each involved parcel as a legal parcel. For purposes of this subsection, parcels separated for assessment purposes are not legal parcels for purposes of processing a lot line adjustment;
Two copies of a preliminary title report concerning the property, not more than 30 days old;
Seven copies of a tentative lot line adjustment map accurately drawn to scale. Measurements shall be identified by feet, square feet or acres to the nearest tenth. The map shall be 24 by 36 inches in size and shall specifically show the following:
a. All exterior and interior lines shall be shown on the map and shall be identified by course and bearing description, based on survey data, calculated data, or information of record;
b. Proposed new lines and lines to be eliminated shall be so identified in written notation or by legend. Lines to be eliminated shall be dashed or otherwise drawn so as to be clearly distinguished from and subordinate to remaining new lines;
c. All existing structures shall be accurately located on the original parcels together with their dimensions, the distance between structures and the number of stories and height of each structure;
d. The distance from the existing structures to the boundary lines of the new parcel on which the structures are located;
e. The distance from existing wells, septic tank and leach fields to existing and proposed property lines;
f. The locations, purpose and width of all existing and proposed easements, streets and appurtenant utilities;

i. A copy of any existing Williamson Act agreements affecting the parcels to be adjusted;
j. The assessor parcel numbers of all presently existing lots involved in the application;
- The required fees and deposits.
C. Following a determination by the Planning Department that the application is complete, the matter shall be set for consideration by the Environmental Review Committee.
D. Notice of the hearing shall be mailed or delivered at least 10 days prior to the hearing to the owner of the real property or his agent, and to the project applicant, if any.
E. Notice of the hearing shall be mailed or delivered at least 10 days prior to the hearing to all owners of real property immediately adjoining the property that is the subject of the hearing, as shown on the latest equalized assessment roll.
F. The documents submitted shall be reviewed by the Environmental Review Committee (ERC) who shall approve the lot line adjustment if they find each condition set forth in subsection A of this section is met. The ERC may impose conditions on their approval to conform to local zoning and building requirements or to facilitate the relocation of existing utilities, infrastructure or easements. The ERC’s decision shall be final unless appealed to the Planning Commission as provided in subsection G of this section.
G. Appeals of ERC’s action with respect to lot line adjustments shall be made to the Planning Commission in accordance with the provisions of Chapter 17.455 SMC. An appeal must be filed in writing within five days from issuance of the ERC’s decision on the matter, and be accompanied by any required fee. On appeal, the Planning Commission shall approve the lot line adjustment if it finds that each condition set forth in subsection A of this section is met. The Planning Commission may add, delete or modify conditions if the Planning Commission determines that such changes are necessary to ensure that the lot line adjustment conforms to the State Subdivision Map Act and this code.
H. For any specific project for which a lot line adjustment application is filed, the Planning Commission, rather than the Environmental Review Committee, shall approve, conditionally approve, or deny such application ordinarily subject to approval by the Environmental Review Committee if the application is submitted concurrently with an application requiring approval by the Planning Commission. Under such circumstance, the Planning Commission’s determination on the lot line adjustment request may be appealed to the City Council pursuant to Chapter 17.455 SMC. Any such appeal must be filed in writing within five days from issuance of the Planning Commission’s decision on the matter, and be accompanied by any required fee.
I. Following approval of the lot line adjustment and after satisfying all conditions of approval, the applicant shall submit to the City Engineer for review and approval revised deeds for transfer of the property and thereafter shall record the documents and submit copies of the recorded documents to the Planning Department. No record of survey shall be required unless required by Section 8762 of the Business and Professions Code. Subject to the approval of the City Engineer, in lieu of satisfying development conditions, the applicant may post a bond or other acceptable security satisfactory to the City in form and amount to secure applicant’s agreement to satisfy development conditions.
J. A lot line adjustment approval shall be valid for 18 months from the date of approval and if the revised lots are not a matter of record within that 18-month period, the approval shall expire. Such approval may be extended by the Environmental Review Committee for up to one year from the expiration date if an application for such extension is filed prior to the expiration date and if the Environmental Review Committee finds that the lot line adjustment is consistent with the then-existing General Plan and Zoning Ordinance and conforms to the then-existing improvement standards of this chapter. The Environmental Review Committee may condition its approval of the extension request to address issues of conformity as well as to address other potential impacts of the lot line adjustment. The ERC’s action on an extension shall be subject to appeal to the Planning Commission in accordance with the provisions of Chapter 17.455 SMC. An appeal must be filed in writing within five days from issuance of the ERC’s decision on the matter, and be accompanied by any required fee.
