22.90.010 - Purpose of Chapter. ¶
This Chapter provides procedures for the preparation, filing, processing, and approval or denial of Lot Line Adjustment applications, consistent with the policies of the Marin Countywide Plan and the requirements of Map Act Section 66412.d.
(Ord. No. 3577, 2012)
22.90.020 - Applicability. ¶
As provided by Map Act Section 66412(d), the Lot Line Adjustment procedure is for the purpose of adjusting lot lines between two to four existing adjacent parcels, where land taken from one parcel is added to an adjacent parcel and where no more parcels are created than originally existed. For the purposes of this Chapter, an "adjacent parcel" is one that directly touches at least one of the other parcels involved in the adjustment. Lot line adjustments involving five or more adjacent parcels shall be subject to the requirements of Chapter 22.84 (Tentative Maps).
(Ord. No. 3577, 2012)
22.90.030 - Adjustment Application and Processing. ¶
A Lot Line Adjustment application shall be prepared, filed and processed as provided by this Section.
A.
Application content. A Lot Line Adjustment application shall include all information and other materials prepared as required by the Application Submittal Guide provided by the Agency. If a lot was created prior
to current subdivision map requirements, a Certificate of Compliance (Chapter 22.96 (Certificates of Compliance)) may be required to document that the parcel is a legal lot of record.
B.
Processing. Lot Line Adjustment applications shall be submitted to the Agency and shall be processed in compliance with the procedures specified by Chapter 22.40 (Application Filing and Processing). No environmental review (Section 22.40.060, Environmental Review) shall be required, in compliance with Section 15305 of the CEQA Guidelines.
(Ord. No. 3577, 2012)
22.90.040 - Decisions and Findings. ¶
The Review Authority shall determine whether the parcels resulting from the adjustment will conform with the applicable provisions of this Development Code. The Review Authority may approve, conditionally approve, or deny the Lot Line Adjustment in compliance with this Section. Decisions may be appealed in compliance with Chapter 22.114 (Appeals).
A.
Required findings. The Review Authority shall approve the Lot Line Adjustment only if all of the following findings are made:
1.
The proposed lot line adjustment is limited to four or fewer existing adjoining lots.
2.
Each of the affected lots is a separate legal lot of record because it was created in compliance with the applicable subdivision regulations in effect at the time of its creation.
3.
The proposed lot line adjustment would not result in the creation of additional lots.
4.
The proposed lot line adjustment would comply with policies of the Countywide Plan, and any applicable community plan, and the Local Coastal Program (if applicable).
5.
The proposed lot line adjustment would comply with zoning, development, and relevant subdivision provisions of Titles 18, 20, 22 and 24 of the Marin County Code, including those which address minimum lot size, lot design and configuration, street frontage and building setbacks from all property lines.
An adjustment for which any of the above findings cannot be made may instead by resubmitted as a subdivision in compliance with Section 22.80.030 (applicability).
B.
Conditions of approval. In approving a Lot Line Adjustment, the Review Authority shall adopt conditions only as necessary to conform the adjustment and proposed parcels to the requirements of this Development Code and Title 19 (Building Regulations) of the County Code, or to facilitate the relocation of existing utilities, infrastructure, or easements.
