It provides information on the type of zoning, overlay districts, enacting ordinance numbers and effective dates.Zoning Code governs the use and development of land in Seattle. Zoning districts specify a category of uses (e.g., single-family residential, multifamily residential, commercial, industrial, etc.) including specific overlays and are applied by ordinance. Symbolized on the value DETAIL_DESC (group 28 categories).

Detailed zoning regulations and development restrictions for this property

Note: This map is not an official zoning map. For precise zoning information, please call or visit the Seattle Municipal Tower, Seattle Department of Construction and InspectionsZoning areas where Mandatory Housing Affordability requirements may apply.Mandatory Housing Affordability requires new development to contribute to affordable housing by including affordable housing in the development or making a payment to the City’s Office of Housing to support affordable housing. The amount of the MHA contribution varies based on a property’s _location and other factors specified in Seattle Municipal Code Chapters 23.58B and 23.58C.

Mandatory Housing Affordability requires new development to contribute to affordable housing by including affordable housing in the development or making a payment to the City’s Office of Housing to support affordable housing. The amount of the MHA contribution varies based on a property’s _location and other factors specified in Seattle Municipal Code Chapters 23.58B and 23.58C. 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.

Mapping application to support research related to City of Seattle land use, zoning, and other property related development regulations. Includes layers related to zoning, parking, tree regulation, and environmentally critical areas.

These layers are used as part of the City of Seattle Zoned Development Capacity Model 2016. Includes all input and output layers..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 existing and potential development yields the capacity for new residential and commercial development.There is a report of summary findings available as part of Seattle 2035 as well as resources for reports, methodologies and data.When downloading the data, please select a layer and then "GDB Download" under "Additional Resources" to preserve long field names. The associated file geodatabase contains all the feature classes for the 10 layers represented.

This report presents probabilistic seismic hazard maps for Seattle, Washington, based on over 500 3D simulations of ground motions from scenario earthquakes. These maps include 3D sedimentary basin effects and rupture directivity. Nonlinear site response for soft-soil sites of fill and alluvium was also applied in the maps. The report describes the methodology for incorporating source and site dependent amplification factors into a probabilistic seismic hazard calculation. 3D simulations were conducted for the various earthquake sources that can affect Seattle: Seattle fault zone, Cascadia subduction zone, South Whidbey Island fault, and background shallow and deep earthquakes. The maps presented in this document used essentially the same set of faults and distributed-earthquake sources as in the 2002 national seismic hazard maps. The 3D velocity model utilized in the simulations was validated by modeling the amplitudes and waveforms of observed seismograms from five earthquakes in the region, including the 2001 M6.8 Nisqually earthquake. The probabilistic seismic hazard maps presented here depict 1 Hz response spectral accelerations with 10%, 5%, and 2% probabilities of exceedance in 50 years. The maps are based on determinations of seismic hazard for 7236 sites with a spacing of 280 m.

 The maps show that the most hazardous locations for this

frequency band (around 1 Hz) are soft-soil sites (fill and alluvium) within the Seattle basin and along the inferred trace of the frontal fault of the Seattle fault zone. The next highest hazard is typically found for soft-soil sites in the Duwamish Valley south of the Seattle basin. In general, stiff-soil sites in the Seattle basin exhibit higher hazard than stiff-soil sites outside the basin. Sites with shallow bedrock outside the Seattle basin have the lowest estimated hazard for this frequency band. [Summary provided by the USGS.]
