IDENTIFICATION INFORMATION

1.1

Citation

Originator

Metro Data Resource Center

Zoning designation boundaries from local zoning ordinances. This layer has been reviewed by each jurisdiction and corrections were made by Metro where advised. Some errors are likely to remain and the jurisdiction should be used as the ultimate source for the actual zoning of a given property. In jurisdictions that use one map for comprehensive land use plan designations and zoning designations, the plan and zoning files are the same.

Purpose

Used by planners and citizens to check zoning regulations.

Supplemental information

ArcView legends: Zone_cl.avl - draws each zoning classification in a different color.
Zoneg_cl.avl - draws the six generalized zone classifications in a different color.

DATA QUALITY INFORMATION

2.4

Horizontal positional accuracy

Registered to tax lots.

Zoning information was collected from the 24 cities and three counties in the region. The maps were digitized and check plots were reviewed by each of the jurisdictions. Corrections were made on the digital copy. The approx. 500 local zoning designations were captured on the map and a lookup table was created which categorized the local designations into 18 categories which are displayed on regional maps.

The REGPLAN and REGPLANGEN data items were renamed to PLAN_CLASS and PLANGEN_CL.

This layer was reprojected to the NAD83/91 projection (also known as HPGN) as part of a conversion of all RLIS map layers.

The standard regional zoning classification system was expanded from 21 to 26 classes. The zone_cl.avl and plan_cl.avl (legend files) have all 26 classifications. This made the legend larger. The zone_gcl.avl and plan_gcl.avl are unchanged and still show the zones aggregated into 6 classes.

Added MUC as a seventh generalized class.

Projection information (.prj file), compatible with ArcGIS 8.1, was added to the layer.

ENTITY AND ATTRIBUTE INFORMATION

Overview description

Table Name	Column	Sample Domain Value	Definition
Zoning.dbf	--	--	Description of the zoning polygon attributes.
	Area	--	Area in square feet.
	City_no	--	Census jurisdiction number code.
	Zone	--	Local jurisdiction zoning designation.
	City	--	City name.
	Describe	--	Description of the local jurisdiction zoning designation.
	Zone_class	--	26 regional classifications into which the zoning is generalized.
		FF	Agriculture or Forestry- activities suited to commercial scale agricultural production, typically with lot sizes of 30 acres or more.
		RRFU	Rural or Future Urban- residential uses permitted on rural lands or areas designated for future urban development, with minimum lot sizes of one acre or more.
		SFR1	Single Family 1- detached housing with minimum lot sizes from 20,000 quare feet and up.
		SFR2	Single Family 2- detached housing with minimum lot sizes ranging from 12,000 to 20,000 square feet.
		SFR3	Single Family 3- detached housing with minimum lot sizes ranging from 8,500 to 12,000 square feet.
		SFR4	Single Family 4- detached housing with minimum lot sizes from 6,500 to 8,500 square feet.
		SFR5	Single Family 5- detached housing with minimum lot sizes ranging from 5,500 to 6,500 square feet.
		SFR6	Single Family 6- detached housing with minimum lot sizes from 4,000 to 5,500 square feet.
		SFR7	Single Family 7- detached housing with minimum lot sizes ranging from 0 to 4,000 square feet.
		MFR1	Multi-family 1- housing and or duplex, townhouse and attached single-family structures allowed outright. Maximum net allowable densities range from 2 to 25 units per acre, with height limits usually set at 2 1/2 to 3 stories.
		MFR2	Multi-family 2- housing accommodating densities ranging from 25 to 50 units per acre. Buildings may exceed three stories in height.
		MFR3	Multi-family 3 - housing accomodating densities ranging from 50 to 100 units.
		MFR4	Multi-family 4- housing accommodating densities greater than 100 units. This is the densest of the multi-family zones and would require greater use of vertical space and buildings with multiple stories.
		CN	Neighborhood Commercial- small scale commercial districts permitting retail and service activities such as grocery stores and laundromats supporting the local residential community. Floor space and/or lot size is usually imited from 5,000 to 10,000 square feet.
		CG	General Commercial- larger scale commercial districts, often with a more regional orientation for providing services. Businesses offering a wide variety of goods and services are permitted and include highway and strip commercial zones.
		CC	Central Commercial- allows a full range of commercial activities typically associated with central business districts. More restrictive than general commercial in the case of large lot and highway oriented uses, but usally allows multi-story development.
		CO	Office Commercial- districts accomodating a range of business, professional and medical office facilities, typically as a buffer between residential areas and more intensive uses.
		IL	Light Industrial- districts permitting warehousing and light processing and fabrication activities. May allow some commercial activities.
		IH	Heavy Industrial- districts permitting light industrial and more intensive industrial activities such as bottling, limited chemical processing, heavy manufacturing and similar uses.
		IMU	Mixed Use Industrial- districts accommodating a mix of light manufacturing, office and retail uses.
		IA	Industrial Area- districts designated exclusively for manufacturing, industrial, warehouse and distribution related operations.
		MUC1	Mixed Used Center 1- combines residential and employment uses in town centers, main streets and corridors.
		MUC2	Mixed Use Center 2- combines residential and employment uses in light rail station areas and regional centers.
		MUC3	Mixed Use 3- combines residential and employment uses in central city locations. Mixed use is weighted toward residential development.
