REQUIRED: A brief narrative summary of the data set.

The Biscuit Flat Quadrangle is located in the northwestern Phoenix metropolitan area, betweenInterstate 17 (I-17) and the Agua Fria River (Figure 1). The quadrangle is bounded by latitudes33 45'00 'N and 33 52'30 'N, and longitudes 112 07'30 'W and 112 15'00 'W. Unlike areas to the southand southeast, the Biscuit Flat area is not (as yet) urbanized. However, knowledge of the distribution andcharacter of bedrock and surficial deposits may be important to make informed decisions concerningfuture management of the land and its resources. Geologic mapping of the Biscuit Flat Quadrangle isrelated to other 1 :24,000 scale mapping projects in and around the Phoenix metropolitan area (Figure 1).Geologic mapping was based on both field observations and interpretation of aerial photographs and soilsurveys. Mapping of Quaternary surficial deposits was initially done by Huckleberry, whereas finalmapping and interpretation of surficial deposits and bedrock areas was completed by Leighty. A limitedamount of unpublished Arizona Geological Survey mapping (by Steve Reynolds and Mike Grubensky forthe Phoenix North 1:100,000 scale geologic map) augmented the new mapping of this report. Also, themapping of Tertiary rocks by Jagiello (1987) is locally similar to that of this report. Aerial photographiccoverage of the quadrangle is available from various sources (e.g., U.S.G.S., Bureau of LandManagement, etc.), and includes black-and-white (1:40,000 scale, dated 9-6-92), false-color high-altitude(dated 5-17-81), and color (1:24,000 scale, dated 10-25-77) photographs. Soil information was compiledfrom USDA Maricopa County soil surveys (Hartman, 1977; Camp, 1986). This project was funded by theEnvironmental Protection Agency through the State Indoor Radon Grant Program, the U.S. GeologicalSurvey via the STATEMAP program, and the Arizona Geological Survey.Geologic map of the Biscuit Flat 7.5' Quadrangle, Maricopa County, Arizona - report and one map sheet, scale 1:24,000.

This dataset contain the parcels from the Maricopa County Assessor's office. The area covered is in Maricopa County (Phoenix metro area), Arizona. Major cities include Phoenix, Scottsdale, Mesa and Tempe. Various types of property usage are depicted in this layer. The most common are residential, commercial, industrial and agricultural properties. Multiple sources were used to collect the information including but not limited to CAD packages, aerial photography, and digitizing from paper maps. Adjustments are made where necessary in the process of updating and some parcel lines are only approximate. In cases where a line adjustment might create a loss of landsize it is typically taken out from the right of way to minimize the loss of landsize in the property. The line symbology for different property lines are not available in this dataset. In addition to standard fields the data has unique assessor parcel number for identification, basic temporal information and the location of property.

This is the digitized version of a map of the Hohokam canal system in what is now the Phoenix metropolitan area. It is based on the thesis research by J. B. Howard (Howard, J. (1990). Paleohydraulics : techniques for modeling the operation and growth of prehistoric canal systems. Thesis (M.A.)--Arizona State University, 1990). The original paper map is based on previous archaeological data, overlayed onto USGS 7.5 minute quadrangle maps to recreate the canal pattern.

Star Well 7.5-minute quadrangle is located approximately 50 miles northwest of Phoenix and approximately 30 south of Wickenburg, in the Hassayampa Plain, northwestern Maricopa County, Arizona. Most of the study area is covered by Quaternary and late Tertiary distal piedmont deposits in a broad basin. The Belmont Mountains and associated piedmonts are in the extreme southwestern corner of the quadrangle. The Big Horn, Harquahala, and Vulture mountains are to the west and north of the quadrangle. The Hassayampa River is to the east. Jackrabbit Wash, heading in the proximal piedmonts of the Big Horn and Vulture mountain, and Star Well, heading in the Vulture Mountains, are the two major drainages in the study area. These washes are incised up to four meters into older Pleistocene deposits. Smaller tributary washes form on adjacent older Pleistocene deposits and generally are not incised more than two meters.

Use the app to find the downloadable area within Jackson County - 2 Foot Contour MapThe 2-foot Contour Map shows contours that were derived from several different LiDAR projects in the Rogue Valley over the last 10 years. The map can be used to both download and view the contour data. To use the map, search or zoom in to an address. When zoomed in to a specific scale, the map will change from the downloadable areas layer to 2-foot interval contour lines. The LiDAR Project Dates layer can be used to identify the date when the elevation was collected in an area. Please note that data is available only for the valley floor areas at this time.The 2ft contours were created from 1-meter pixel DEM and then cleaned to remove very small elevation changes and to create a smooth contour line. This information should not be used to create topographic surveys or other applications where the precise elevation of a location is required. For additional information on LiDAR in Oregon or to download the source data, please visit the DOGAMI Lidar Viewer.The downloadable data is a zipped ESRI Shapefile and is projected to Oregon State Plane South (Intl Feet) with NAD 1983 datum.

The Daggs Tank 7.5-minute Quadrangle is located approximately 40 miles (60 km) northwest of downtown Phoenix on the east side of Hassayampa Plain. Much of the map area consists of the western piedmont of the White Tank Mountains, but the western third of the map area is dominated by deposits of the south-flowing Hassayampa River, a major regional drainage in central Arizona. The surficial geology depicted in this map is modified from Field and Pearthree (1991b), and includes new field mapping and aerial photograph interpretation using high-resolution digital images provided by Maricopa County. Tertiary volcanic rocks were mapped for this study, but much of the rest of the bedrock was mapped by Barret (1976) and modified locally based on new field mapping, and on mapping and examination of rock units in the adjacent Wagner Wash Well 7.5-minute Quadrangle (Ferguson et al., 2004).

CDFW BIOS GIS Dataset, Contact: Jason Giessow, Description: This dataset provides the known distribution of Canary Island date palm (Phoenix canariensis) in southern Orange County. The surveys were conducted from May to June, 2007 and were funded by the California Department of Fish and Game. There are four other datasets on invasive plants for this area delineating the distribution of pampas grass, Arundo, Mexican fan palm, and 12 other invasive species.

The TIGER/Line shapefiles and related database files (.dbf) 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 shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined by local participants as part of the 2020 Census Participant Statistical Areas Program. The Census Bureau delineated the census tracts in situations where no local participant existed or where all the potential participants declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the density of settlement. Physical changes in street patterns caused by highway construction, new development, and so forth, may require boundary revisions. In addition, census tracts occasionally are split due to population growth, or combined as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features. They may follow legal boundaries such as minor civil division (MCD) or incorporated place boundaries in some States and situations to allow for census tract-to-governmental unit relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census and beyond, the census tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.

Assessment of the character of flood hazards and the extent of flood-prone areas onthe piedmonts of Arizona is an increasingly important concern to floodplain managers asurban areas continue to expand. Piedmonts are the low-relief, gently sloping plainsbetween mountain ranges and the streams or playas that occupy the lowest portions of thevalleys. Proper management of flood hazards on piedmonts is important because much ofsouthern, central, and western Arizona is composed of piedmonts; they comprise most ofthe developable land around Phoenix and other rapidly expanding population centers of theState.Management of flood hazards in Arizona and elsewhere in the western UnitedStates is complicated because portions of many piedmonts are composed of active alluvialfans. During floods, these fans are subject to widespread inundation and local high velocityflow, and substantial changes in channel patterns may occur. Development thatproceeds on piedmonts without regard to the locations of active alluvial fans is likely toplace people and property at risk during large floods.Report and 4 map sheets.

The North of Oracle 7 ' Quadrangle is located in southeastern Pinal County about 30 miles north of Tucson, Arizona, and lies north and northwest of the town of Oracle. The northeastern corner of the map area encompasses a portion of the western flank of the Black Hills. Signal Peak is just out of the map area in the adjacent Mammoth 7 ' Quadrangle to the east. The southeast corner of the map area includes the northern outskirts of the town of Oracle and the large Tucson Wash drainage. The dominant physiographic feature in the map area, however, is Camp Grant Wash, the major drainage for the basin between the Black Hills and Black Mountains, which cuts through the northern part of the map area as it drains northeast to the San Pedro River. The maximum elevation in the map area is about 4400 feet in the southwest corner, and the minimum elevation is about 3200 feet where Camp Grant Wash exits the map area to the north. Bedrock and surficial geology in the study area were mapped between October 2001 to June 2002 as part of a multiyear mapping program directed at producing complete geologic map coverage for the Phoenix-Tucson metropolitan corridor. Additional bedrock mapping, done by J. Spencer in 2003, outlined an extensive pediment developed on porphyritic granite near the center of the south edge of the map. This map is designated version 2.0, with a new publication date, because of this new mapping. Purpose: Geologic mapping north of Tucson is part of continuing efforts by the AZGS to map the geology of the Phoenix - Tucson urban corridor. This map builds on and complements previous and concurrent surfical geologic mapping efforts in the Tucson area.

Most of southern and western Arizona lie within the Basin and Rangephysiographic province, a region characterized by broad valleys and linear mountainranges. The valleys are deeply filled with alluvium that has eroded from adjacentmountains during the last 10 My 1. This aggradation has been driven by tectonism andclimate change, although regional tectonic stability within the last 5 My suggests thatclimate change is the more recent dominant driving force (Morrison, 1985). Climaticfluctuations between relatively wet and dry conditions have resulted in pulses ofaggradation producing a mosaic of different aged alluvial deposits in piedmont areas.Urban development on piedmonts, especially in the Phoenix Basin, has created a need tobetter understand the distribution and nature of these deposits. Surficial geologic mapscharacterize and distinguish different piedmont deposits on the basis of age and genesis.Such information provides baseline data for evaluating geologic hazards potential (e.g.,Pearthree, 1991), locating possible source areas for industrial minerals (e.g., Wellendorf etaI., 1986), and determining locations favorable for groundwater recharge (e.g.,Huckleberry, 1994). Moreover, these maps are also useful for assessing the potential forburied cultural resources and providing insight into local geologic history and landscapeevolution.This report presents the results of surficial geologic mapping in the Wittmann andHieroglyphic Mountains SW 7.5' quadrangles located northwest of metropolitan Phoenix(Figure 1). The project area includes segments of U.S. Highway 60, State Route 79, andthe Central Arizona Project Canal, and is contiguous to the south with the White TanksMountain piedmont area previously mapped by Field and Pearthree (1991).(24 pages; 2 map sheets, map scale 1:24,000)
