Hearing Date: 1/12/06

Staff: Thamas Osborn (786-7129).

Background:

Regulation of land divisions by local governments.
The legislative body of a city, county, or town must adopt regulations and procedures governing the approval of proposed divisions of land within its jurisdictional boundaries. Such regulations must be adopted by ordinance and are enforced by appointed administrative personnel, who must provide written factual findings supporting decisions to approve or deny proposed land divisions.
A property owner must have a proposed division of land reviewed and approved by the county, city, or town in which the land is located. Such divisions of land are generally categorized as either "subdivisions" or "short subdivisions." Subdivisions are defined as land divisions resulting in five or more lots, tracts, or parcels. Short subdivisions are defined as land divisions resulting in four or fewer lots, tracts, or parcels. However, a city, town or Growth Management Act (GMA) planning county may adopt a local ordinance increasing to a maximum of nine the number of lots, tracts, or parcels that may be contained in a short subdivision located within the boundary of an urban growth area (UGA).

The GMA and residential density requirements within an UGA.
Although the GMA includes provisions pertaining to density and the reduction of sprawling low-density development, neither "density" nor "residential density" is defined in the Act. The Department of Community, Trade, and Economic Development, defined "residential density" in its September 2004, guidance paper, Urban Densities - Central Puget Sound Edition, as, in part, the number of dwelling units over a specified land area.

The GMA does not prescribe a uniform minimum residential density, nor does the Act require jurisdictions to establish uniform minimum residential densities. Growth Management Hearings Boards have, however, issued decisions pertaining to residential densities. The Central Puget Sound Growth Management Hearings Board (CPSGMHB), for example, noted in its 1995 decision from Bremerton, et al., v. Kitsap County, that:

"...rather than adopt a maximum urban lot size, the Board instead adopts as a general rule a "bright line" at four net dwelling units per acre. Any residential pattern at that density, or higher, is clearly compact urban development and satisfies the low end of the range required by the [GMA]. Any larger urban lots will be subject to increased scrutiny by the Board to determine if the number, locations, configurations and rationale for such lot sizes complies with the goals and requirements of the [GMA]...Any new residential land use pattern within a UGA that is less dense is not a compact urban development pattern, constitutes urban sprawl, and is prohibited. There are exceptions to this general rule...However, this circumstance can be expected to be infrequent within the UGA and must not constitute a pattern over large areas."

Summary of Bill:

Mandatory zoning ordinances permitting the division of single lots into multiple nonconforming lots.
Subject to specified conditions, certain cities, towns, and counties must have zoning ordinances that permit a single lot to be divided into two or more lots which will be recognized as legal and conforming for purposes of development. This requirement applies under the following circumstances:

• The original lot must be at least twice the minimum lot size required under existing zoning regulations;
• The averaged area of all resulting lots shall be not less than the legally required minimum lot size;
• The averaged width and depth of all resulting lots must be at least fifty percent of any applicable requirements regarding minimum width and depth;
• The city, town, or county must be planning under the GMA;
• The lot or parcel must be located in a residentially zoned district within an UGA; and
• All of the resulting lots must have adequate access to a public street.

A city, town, or county not planning under the GMA has the option of adopting such zoning ordinances, but is not under a legal requirement to do so.

Mandatory zoning ordinances permitting boundary line adjustments that result in nonconforming lots.
Subject to specified conditions, certain cities, towns, and counties must have zoning ordinances that permit the adjustment of boundary lines between abutting lots under the same ownership so as to allow the creation of one or more lots of nonconforming size or dimension that are recognized as legal and conforming for purposes of development. These requirements apply under the following circumstances:

• The adjustment of the boundary line does not result in the creation of additional lots;
• The averaged area of all resulting lots shall be not less than the legally required minimum lot size;
• The averaged width and depth of all resulting lots must be at least fifty percent of any applicable requirements regarding minimum width and depth;
• The city, town, or county must be planning under the GMA;
• The lot or parcel must be located in a residentially zoned district within an UGA; and
• All of the resulting lots must have adequate access to a public street.

A city, town, or county not planning under the GMA has the option of adopting such zoning ordinances, but is not under a legal requirement to do so.
