22A.010.020 Authority.

The UDC is enacted under the authority granted to the city of Marysville by the Constitution of the State of Washington, the Optional Municipal Code (RCW Title 35A) and other sections of the Revised Code of Washington (RCW). (Ord. 2852 § 10 (Exh. A), 2011).

22A.010.030 Purpose.

The general purposes of this title are:

(1) To establish regulatory procedures and standards for review and approval of all proposed development in the city.

(2) To foster and preserve public health, safety, comfort, and welfare, and to aid in the harmonious, orderly, aesthetically pleasing, and socially and economically beneficial development of the city, in accordance with the comprehensive plan.

(3) To adopt a development review process that is:

(a) Efficient, in terms of time and expense;

(b) Effective, in terms of addressing the natural, historic, and aesthetic resources and public facility implications of any proposed development, while also protecting and improving the quality of life in the city; and

(c) Equitable, in terms of consistency with established regulations and procedures, respect for the rights of all property owners, and consideration of the interests of the citizens and residents of the city.

(4) To implement the comprehensive plan of the city by:

(a) Establishing regulations and conditions governing the erection and future use of buildings and other structures and the uses of land planned for the future as specified in the comprehensive plan;

(b) Securing safety from fire, panic, and other dangers;

(c) Lessening automobile congestion of the streets;

(h) Establishing performance standards that apply to all new development as well as the redevelopment of all lands in the city; and

(i) Defining the functions of the community development department, hearing examiner and city council and other relevant agencies with respect to the administration and enforcement of this development code.

(6) To provide for a penalty for the violation of this development code.

(8) To encourage land use decision making in accordance with the public interest and applicable laws of the state of Washington.

(9) To promote general public safety by regulating development of lands containing physical hazards and to minimize the adverse environmental impacts of development. (Ord. 2852 § 10 (Exh. A), 2011).

Where a difference exists between this title and other city regulations, the more restrictive requirements shall apply.

(4) Where more than one part of this title applies to the same aspect of a proposed use or development, the more restrictive requirement shall apply. (Ord. 2852 § 10 (Exh. A), 2011).

(1) In case of inconsistency or conflict, regulations, conditions or procedural requirements that are specific to an individual land use shall supersede regulations, conditions or procedural requirements of general application.

(2) A land use includes the necessary structures to support the use unless specifically prohibited or the context clearly indicates otherwise, subject to other standards in code and any required permits for structures.

(3) Chapter and section headings, captions, illustrations and references to other sections or titles are for reference or explanation only and shall not be deemed to govern, limit, modify, or in any manner affect the scope, meaning, or intent of any section. In case of any ambiguity, difference of meaning or implication between the text and any heading, caption or illustration, the text and the permitted use tables in Chapters 22C.010 and 22C.020 MMC shall control. All applicable requirements shall govern a use whether or not they are cross-referenced in a text section or land use table.

(13) The word “days” refers to calendar days. (Ord. 2852 § 10 (Exh. A), 2011).

22A.010.070 Interpretation – Land use.

(1) If a use is not specifically or generally listed in the permitted uses table in MMC 22C.010.060 or 22C.020.060, the community development director shall determine whether a proposed land use is allowed in a zone.

The community development director’s determination shall be based on whether or not permitting the proposed use in a particular zone is consistent with the purposes of this title and the zone’s purpose as set forth in Chapter 22A.030 MMC, by considering the following factors:

(a) The physical characteristics of the use and its supporting structures (including but not limited to scale, traffic and other impacts, and hours of operation) are of the same basic nature as a use or uses specifically or generally listed in the applicable zoning district;

(b) The use complements or is compatible with other uses permitted in the zone.

(2) The decision of the community development director shall be final unless the applicant or an adverse party files an appeal to the hearing examiner pursuant to Chapter 22G.010 MMC, Article VIII, Appeals. (Ord. 3207 § 1, 2022; Ord. 2852 § 10 (Exh. A), 2011).

22A.010.075 Promulgation of rules, procedures and interpretations.

The community development director is authorized to promulgate administrative rules, procedures and interpretations consistent with the terms of this title.

(Ord. 3207 § 2, 2022).

22A.010.080 Interpretation – Zoning maps.

Where uncertainties exist as to the location of any zone boundaries, the following rules of interpretation, listed in priority order, shall apply:

(1) Where district boundaries are indicated as approximately following street lines, alley lines, or lot lines, such lines shall be construed to be such boundaries.

(2) Where boundaries are indicated as following approximately lot lines, the actual lot lines shall be considered the boundaries. In subdivided property or where a district boundary divides a lot, the location of such boundary, unless the same is indicated by dimensions, shall be determined by use of the scale appearing on the map.

(3) Where boundaries are indicated as following lines of ordinary high water, or government meander line, the lines shall be considered to be the actual boundaries. If these lines should change the boundaries shall be considered to move with them.

(4) Where any street, road or alley is hereafter officially vacated or abandoned, the regulations applicable to each parcel of abutting property shall apply to that portion of such street, road or alley added to the property by virtue of such vacation or abandonment.

(5) All land hereafter annexed to the city shall be zoned consistent with the comprehensive plan designation previously assigned to the property by the city of Marysville. In the event the property does not have a comprehensive plan designation assigned to it by the city of Marysville, it shall be designated R-4.5 as an interim zoning classification, until such time when the city amends its comprehensive plan and assigns a land use designation and corresponding zoning to the property.
