Sphere of Influence (SOI) of Incorporated Cities. The purpose of the sphere of influence is to ensure the provision of efficient services while discouraging urban sprawl and the premature conversion of agricultural and open space lands by preventing overlapping jurisdictions and duplication of services.

PM2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated. Outdoor PM2.5 levels are most likely to be elevated on days with little or no wind or air mixing. Particles in the PM2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. Exposure to fine particles can also affect lung function and worsen medical conditions such as asthma and heart disease. Scientific studies have linked increases in daily PM2.5 exposure with increased respiratory and cardiovascular hospital admissions, emergency department visits and deaths. Studies also suggest that long term exposure to fine particulate matter may be associated with increased rates of chronic bronchitis, reduced lung function and increased mortality from lung cancer and heart disease. People with breathing and heart problems, children and the elderly may be particularly sensitive to PM2.5. This federal PM 2.5 layer shows the boundary of the Yuba City-Marysville PM 2.5 nonattainment area - the area in which standards for PM 2.5 containment have not been met. It includes all of Sutter County & a portion of Yuba County.

Zoning codes are a set of rules that regulate what can and can't be done on a particular piece of property. Zoning designations are not available in areas in the incorporated cities of Live Oak and Yuba City.

Census 2010 Tract Data with DemographicsCensus Tracts are the second level of Census Block aggregation. They can also be aggregated from Block Groups. Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. They are the smallest geographic areas for which the Census Bureau publishes data from the decennial census. Census blocks are relatively small in area; for example, a block in a city bounded by streets. However, census blocks in remote areas are often large and irregular and may even be many square miles in area. All 2010 Census blocks nest within every other 2010 Census geographic area, so that Census Bureau statistical data can be tabulated at the block level and aggregated up to the appropriate geographic areas.

This feature layer is a complete account of all incorporated cities, including the boundary and name of each individual city. This is a CAL FIRE dataset and it's primarily used for identifying incorporated areas, which are not eligible for State Responsibility Area (SRA) designation. Secondary uses are for cartographic purposes, e.g. adding city names and city limits to maps, and for creating contact lists for which cities fall within a certain designation. For CAL FIRE, this was especially relevant for notification of cities with Very High Fire Hazard Severity Zones.For this version (16_1), in addition to capturing annexations, we adusted city boundaries where appropriate to match updated county parcel data. These adjustments were typically done in areas where cities are adjacent to SRA, the process did not cover all city boundaries. This story map is part of the Watershed Improvement Program (WIP) and Watershed Information Network (WIN).The California Communities layer is a feature service used in the Sierra Nevada Cascade story map; therefore, it should not be altered or deleted under any circumstances while the story map is in use.

SACOG Region : El Dorado, Placer, Sacramento, Sutter, Yolo, and Yuba Counties in California.The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Census Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. Blocks are the smallest geographic areas for which the Census Bureau publishes data from the decennial census. A block may consist of one or more faces. Block Groups are the first level of Block aggregation.
