A. 
Review Procedure. The following procedure shall be applicable to all subdivision applications:
Subdivisions may be processed using one of the following methods: (1) subdivision without development, (2) subdivision with development, or (3) consolidated subdivision.
1. 
Subdivisions Without Development.
a. 
The application and review for subdivisions without development shall follow this process:
i. 
In order to provide timely and accurate review of subdivision proposals, applications for preliminary plat, site development, and right-of-way must be submitted concurrently.
ii. 
A final plat application shall be reviewed in compliance with SMC § 20.30.450.
2. 
Subdivision with Development.
a. 
The application and review for subdivisions with development shall follow this process:
i. 
Preliminary Plat Application. Review of environmental requirements, availability of utilities, sufficient access, conceptual drainage provisions, frontage improvements, and all dimensional requirements for the applicable zone must be completed. Approval of preliminary plat must be issued before proceeding to subsection (A)(2)(a)(ii) of this section.
ii. 
Building, site development, and right-of-way applications must be submitted concurrently for review. The issuance of all three permits will occur at the same time once all requirements, including the submittal of sufficient surety as required in SMC § 20.30.440, have been met.
iii. 
A final plat application shall be reviewed in compliance with SMC § 20.30.450 when all building permit(s) have been issued.
3. 
Consolidated Subdivision.
a. 
The application and reviews for consolidated subdivisions shall follow this process:
i. 
The review process for a consolidated subdivision requires that all applicable required documents and plans be submitted and reviewed under one application package. All required documents and plans associated with the preliminary plat, building(s), site development, and right-of-way shall be included in the package. The issuance of all permits will occur at the same time once all requirements, including the submittal of sufficient surety as required in SMC § 20.30.440, have been met.
ii. 
A final plat application shall be reviewed in compliance with SMC § 20.30.450 when all building permit(s) have been issued.
B. 
Review Criteria. The following criteria shall be used to review proposed subdivisions:
1. 
Environmental.
a. 
Where environmental resources exist, such as trees, streams, geologic hazards, or wildlife habitats, the proposal shall be designed to fully implement the goals, policies, procedures and standards of the critical areas regulations, Chapter 20.80 SMC, Critical Areas, and the tree conservation, land clearing, and site grading standards sections.
b. 
The proposal shall be designed to minimize grading by using shared driveways and by relating street, house site and lot placement to the existing topography.
c. 
Where conditions exist which could be hazardous to the future residents of the land to be divided, or to nearby residents or property, such as floodplains, landslide hazards, or unstable soil or geologic conditions, a subdivision of the hazardous land shall be denied unless the condition can be permanently corrected, consistent with subsections (B)(1)(a) and (B)(1)(b) of this section, Chapter 20.80 SMC, Critical Areas, and Chapter 13.12 SMC, Floodplain Management.
d. 
Low impact development (LID) techniques shall be applied where feasible to minimize impervious areas, manage stormwater, and preserve on-site natural features, native vegetation, open space and critical areas.
2. 
Lot and Street Layout.
a. 
Lots shall be designed to contain a usable building area. If the building area would be difficult to develop, the lot shall be redesigned or eliminated, unless special conditions can be imposed that will ensure the lot is developed consistent with the standards of this Code and does not create nonconforming structures, uses or lots.
b. 
Lots shall not front on primary or secondary highways unless there is no other feasible access. Special access provisions, such as shared driveways, turnarounds or frontage streets, may be required to minimize traffic hazards.
c. 
Each lot shall meet the applicable dimensional requirements of the Code.
d. 
Pedestrian walks or bicycle paths shall be provided to serve schools, parks, public facilities, shorelines and streams where street access is not adequate.
3. 
Dedications and Improvements.
a. 
The City may require dedication of land in the proposed subdivision for public use.
b. 
Only the City may approve a dedication of park land.
c. 
In addition, the City may require dedication of land and improvements in the proposed subdivision for public use under the standards of Chapter 20.60 SMC, Adequacy of Public Facilities, and Chapter 20.70 SMC, Engineering and Utilities Development Standards, necessary to mitigate project impacts to utilities, rights-of-way, and stormwater systems.
i. 
Required improvements may include, but are not limited to, streets, curbs, pedestrian walks and bicycle paths, critical area enhancements, sidewalks, street landscaping, water lines, sewage systems, drainage systems and underground utilities.
4. 
Unit Lot Subdivision.
a. 
Repealed by Ord. 1027.
b. 
Units may be subdivided into individual unit lots. The parent lot shall meet the applicable development standards.
c. 
As a result of the subdivision, development on individual unit lots may modify standards in SMC § 20.50.020, Exception 2 to Tables SMC §§ 20.50.020(1) and 20.50.020(2).
d. 
Access easements, joint use and maintenance agreements, and covenants, conditions and restrictions identifying the rights and responsibilities of the property owner(s) and/or the homeowners’ association shall be executed for the use and maintenance of common garage, parking and vehicle access areas; solid waste storage and/or collection area(s); on-site recreation; landscaping; underground utilities; common open space; exterior building facades and roofs of individual units; and other similar features, and shall be recorded with the King County Recorder’s Office. These shall be recorded prior to final plat application or shown on the face of the final plat.
e. 
The final plat shall note all conditions of approval. The final plat shall also note that unit lots are not separate buildable lots independent of the overall development and that additional development of the individual unit lots may be limited as a result of the application of development standards to the parent lot.

Commercial and Industrial. This process may be used to divide commercially and industrially zoned property, as authorized by State law. On sites that are fully developed, the binding site plan merely creates or alters interior lot lines. In all cases the binding site plan ensures, through written agreements among all lot owners, that the collective lots continue to function as one site concerning but not limited to: lot access, interior circulation, open space, landscaping and drainage; facility maintenance, and coordinated parking. The following applies:
1. 
Sites subject to binding site plans shall consist of one or more contiguous lots legally created.
2. 
Sites subject to binding site plans may be reviewed independently, or concurrently with a commercial development permit application.
3. 
The binding site plan process merely creates or alters lot lines and does not authorize substantial improvements or changes to the property or the uses thereon.
B. 
Recording and Binding Effect. Prior to recording, the approved binding site plan shall be surveyed and the final recording forms shall be prepared by a professional land surveyor, licensed in the State of Washington. Surveys shall include those items prescribed by State law.
C. 
Amendment, Modification and Vacation. The Director may approve minor changes to an approved binding site plan, or its conditions of approval. If the proposal involves additional lots, rearrangements of lots or roads, additional impacts to surrounding property, or other major changes, the proposal shall be reviewed in the same manner as a new application.
