For properties subject to MHA, the fee areas map specifies the locational dimension of the MHA requirement. MHA amounts in Downtown and South Lake Union have specific requirement levels for each zone as listed in SMC 23.58B and 23.58C. For other areas, the relative high, medium or low aspect of the MHA requirement corresponds to market strength area of the city.

    Description

    This layer is the output of the City of Seattle Zoned Development Capacity Model. To estimate potential development, the City of Seattle maintains a zoned development capacity model that compares existing development to an estimate of what could be built under current zoning. The difference between potential and existing development yields the capacity for new development measured as the number of housing units and the number of potential jobs that could be added.

    Knowledge about capacity enables the City to determine the effects of proposed zoning changes, policy revisions and development trends. It also aids in setting and allocating the 20-year growth targets that must be accommodated by the City’s Comprehensive Plan.


    The model is based on development sites and land use zoning maintained by the Department of Construction and Inspections. Model results for any given development site are not a prediction that a certain amount of development will occur in some fixed time period.

    The actual level of development activity that occurs is a function of a variety of future factors, many of which are beyond our ability to predict or influence. These factors include such things as the future demand for a particular type of development (such as for townhouses, high-amenity multifamily or small-unit multifamily), whether the owner of any particular land is willing to sell or redevelop it, the financial feasibility of developing the land, and the intensity of development when it does occur. Other factors, such as the relative attractiveness of certain areas for living and commerce, and the relative densities allowed by the existing zoning, can cause some areas to be developed earlier or later than others. No one can predict with certainty the total effect of all these factors on the choices made by land developers.

    See the data in action in this web app.

    Supporting resources:

    Disclaimer: This map is the product of an analytical model. The model uses the best available information of current conditions and development assumptions based on observed patterns. As such, the development sites shown as vacant or revdevelopable may not be available for development and others not shown may be available due to current market conditions or landowner preferences.

    Description

    Neighborhood Map Atlas neighborhoods are derived from the Seattle City Clerk's Office Geographic Indexing Atlas. These are the smallest neighborhood areas and have been supplemented with alternate names from other sources in 2020. They roll up to the district areas. The sub-neighborhood field contains the most common name and the alternate name field is a comma delimited list of all the alternate names.The original atlas is designed for subject indexing of legislation, photographs, and other documents and is an unofficial delineation of neighborhood boundaries used by the City Clerks Office. Sources for this atlas and the neighborhood names used in it include a 1980 neighborhood map produced by the Department of Community Development, Seattle Public Library indexes, a 1984-1986 Neighborhood Profiles feature series in the Seattle Post-Intelligencer, numerous parks, land use and transportation planning studies, and records in the Seattle Municipal Archives. Many of the neighborhood names are traditional names whose meaning has changed over the years, and others derive from subdivision names or elementary school attendance areas.Disclaimer: The Seattle City Clerk's Office Geographic Indexing Atlas is designed for subject indexing of legislation, photographs, and other records in the City Clerk's Office and Seattle Municipal Archives according to geographic area. Neighborhoods are named and delineated in this collection of maps in order to provide consistency in the way geographic names are used in describing records of the Archives and City Clerk, thus allowing precise retrieval of records. The neighborhood names and boundaries are not intended to represent any "official" City of Seattle neighborhood map.

    The Office of the City Clerk makes no claims as to the completeness, accuracy, or content of any data contained in the Geographic Indexing Atlas; nor does it make any representation of any kind, including, but not limited to, warranty of the accuracy or fitness for a particular use; nor are any such warranties to be implied or inferred with respect to the representations furnished herein. The maps are subject to change for administrative purposes of the Office of the City Clerk.

    Description

    This polygon feature contains geographic and attribute information for the purpose of depicting Comprehensive Plan Areas within the City of SeaTac, Washington. The data was compiled from existing comprehensive plan information and King County parcel data.This data layer is a reflection of the comprehensive plan that indicates how the City wants to grow and function in the future. The source document contains broad statements of community goals and policies, as well as specific steps for achieving them. The City of SeaTac Comprehensive Plan serves as a "blueprint" for how SeaTac can achieve its vision for itself over the next 20 to 26 years. The Comprehensive Plan will provide the legal basis for future zoning and other implementation measures.City of SeaTac Comprehensive Plan as prepared and adopted by the SeaTac City Council.Last amended in June 23, 2015 (Ord. 15-1009).The change to Angle Lake District Area Boundary was adopted on July 9th, 2015 (Ord. 15-1010).The Washington Growth management Act (GMA) mandates that cities in high growth areas, like Puget Sound region, prepare and adopt comprehensive plans that are consistent with the GMA. The content was last modified in Dec 2013. Boundaries were updated based on parcel data from 02/13/2015, to reflect changes in ROWs and Parcel line, etc. Comprehensive plan boundaries have been adjusted to line up with King County Assessor parcel lines that were improved in 2006 and 2007. Slivers and gaps will appear if this comprehensive plan layer is overlaid with historical parcel, zoning, or comprehensive plan layers. The geometry of this data derives from KC parcel data which is updated quarterly. Then it was intersected with the existing Comprehensive Plan data to transfer the attribute.Incorporated in February 1990, the City of SeaTac is located in the Pacific Northwest, approximately midway between the cities of Seattle and Tacoma in the State of Washington. SeaTac is a vibrant community, economically strong, environmentally sensitive, and people-oriented. The City boundaries surround the Seattle-Tacoma International Airport, (approximately 3 square miles in area) which is owned and operated by the Port of Seattle.
