Urban Heat Data 2021 Evening Traverse

Charlottesville participated in the 2021 NIHHIS-CAPA Urban Heat Island Mapping Campaign, a nationwide citizen-science based effort to collect local data on temperatures and humidity levels across the city. How urban environments and neighborhoods are built affects the amount of heat absorbed and retained, which can increase or reduce the impact of extreme heat events. Increases in extreme heat are one of the top projected impacts Charlottesville will experience from climate change. Data was collected by ~30 volunteers on August 24, 2021 along 7 pre-set routes (5 driving routes and 2 bicycle routes) during a heat wave on a day with high heat and low precipitation. The collected data was processed by CAPA Strategies and is now available through the City of Charlottesville's Open Data Portal. [A PDF Report], including generated maps and explaining the data collection methodology, is also available. More information can be found on the [City's Urban Heat Island Mapping Campaign webpage]. File Notations: * traverses (.shp, vector shapefile) = data collected by campaign participants * rasters (.tif, geotiff) = heat surface models * am = morning; af = afternoon; pm = evening * t = temperature; hi = heat index * f = fahrenheit * e.g. pm_hi_f.tif = evening heat index geotiff raster with fahrenheit values.

This includes ownership by the City of Charlottesville, City School Board, and other variations used in tax assessment and land records. Fields Included: OBJECTID: Internal database identifier GPIN: Geographic Parcel Identification Number OWNER: Current owner name (e.g., "City of Charlottesville") SHAPE: Polygon geometry representing parcel boundaries Source & Processing Notes: Based on authoritative data from the City’s GIS parcel datasets (parcel_area and parcel_point) Ownership identified via dynamic SQL view matching typical City and School Board naming conventions OWNER LIKE 'CITY OF CH''VILLE%' pt.OWNER LIKE 'CITY OF CHARLOTTESVILLE%' pt.OWNER LIKE 'CITY OF, CH''VILLE%' pt.OWNER LIKE 'CITY OF, CHARLOTTESVILLE%' pt.OWNER LIKE 'CITY, OF CHARLOTTESVILLE%' pt.OWNER LIKE 'SCHOOL BD-CITY OF CH''VILLE%' pt.OWNER LIKE 'SCHOOL BOARD%' pt.OWNER LIKE 'SCHOOL, BD-OF CH''VILLE%' pt.OWNER LIKE 'SCHOOL, BOARD OF%' Spatial joins ensure parcel geometry is directly linked to ownership point records Updated regularly to reflect current ownership from tax and assessor records
Mobility Plan Trails: Non-Motorized

This layer will be used for multiple purposes but primarily as a Trails layer for use on the Prince William County CountyMapper XM application so that people can see the trails system available for recreation and other uses. Different from other trails layers in the county system, this layer is also intended for planning and analysis use in order to identify what types of trails are available in the county as well as for gap analysis in order to more purposely develop the trail system effectively. The layer includes information about parks trails and road side trails, and includes information from numerous sources as cited below.
Next Generation 9-1-1 RCL Snap Points in Virginia State Plane South NAD83

Beginning in 2015, the Public Service Communication Board, VITA Integrated Services Program staff, and staffs from public safety answering points (PSAPs) have been planning the deployment of Next Generation 9-1-1 (NG911) for the Commonwealth. Transitioning from the legacy telecommunication network will provide numerous benefits and flexibility looking towards the future. As the emergency services internet protocol network (ESInet) is fully deployed, geospatial call routing will use geographic information system (GIS) data provisioned by authoritative sources. This process includes compiling mutually agreed to available Provisioning Boundary Line segments received and processed by VITA ISP. Segments are connected by Provisioning Boundary Junctions. Road Centerline Snap to Points are created when an existing road centerline feature crosses an agreed-to provisioning boundary and are provided as a feature service [https://vginmaps.vdem.virginia.gov/arcgis/rest/services/NG911/NG911_VA_StatePlaneSouth_NAD83_RCLSnapToPoint/FeatureServer] in Virginia State Plane South. Guidance on connecting to feature services is available here: [https://vginmaps.vdem.virginia.gov/download/ng911/Working_with_VGIN_Feature_Services.pdf].

Next Generation 9-1-1 PSAP Polygons in Virginia State Plane South NAD83

Since 2015, the Public Service Communication Board, VITA Integrated Services Program staff, and staffs from public safety answering points (PSAPs) have been planning and implementing the deployment of Next Generation 9-1-1 (NG911) for the Commonwealth. Transitioning from the legacy telecommunication network provides numerous benefits and flexibility looking towards the future. As the emergency services internet protocol network (ESInet) is deployed, geospatial call routing uses geographic information system (GIS) data and the 911 caller’s location information to identify which PSAP will receive the call. The process of geospatial call routing relies on the civic address layers (address points and road center line maintained by the localities) and a GIS layer representing PSAP boundaries for the operations area for each PSAP. The PSAP boundary file must ensure that every square foot of the Commonwealth is assigned to one and only one PSAP. There can be no gaps or overlaps. PSAPs sharing boundaries with neighboring states must also meet this same rigor to ensure efficient and consistent delivery of every 911 call initiated. This feature class contains the best available PSAP Boundary Line segments received and processed by VGIN into Virginia State Plane South polygons. All segments are agreed to, but geometry may change in the future with new agreements.

Fireboxes are polygons located within first due boundaries. Fireboxes are used in order to determine first due boundaries by calculating time/distance to the centroid of a firebox.
Domestic Fowl Overlay District

The purpose of creating a Domestic Fowl Overlay District is to permit the keeping of chickens, pigeons, doves and other domestic fowl on lots with a rural and semi-rural character that also contain a dwelling unit as a principal use. The keeping of domestic fowl is permitted by right on A-1 zoned properties and on SRR zoned properties by Special Use Permit on a lot with or without a principal residence within this district. To ensure reasonable protection of health, safety and welfare associated with the keeping of domestic fowl, development regulations specific to this district are provisioned. The keeping of domestic fowl is not permitted outside of the Domestic Fowl Overlay District, except on A-1 zoned lots of ten acres or larger. (Ord. No. 11-22, 4-19-11)
Airport Safety Overlay District

The Airport Safety Overlay District is established in recognition of airport related hazards which may endanger lives and property; obstructions which effectively reduce air space required for aircraft take-off, landing, and maneuvering which reduce the utility of the Manassas Regional Airport and the public investment therein. This district shall be in addition to and shall overlay all other zoning districts where it is applied so that any parcel of land lying in the airport impact overlay district shall also lie in one or more of the other zoning districts provided for by this ordinance. The effect is to create a new district which has the characteristics and limitations of the underlying district, together with the characteristics and limitations of the overlay district. It is the intent of this overlay district to regulate vertical encroachment obstructions within the airport protection area. (Ord. No. 04-78, 12-21-04)

Contours Grid

This layer shows the division boundaries for the three sections of contours. Sanborn derived this contour dataset from LiDAR data produced by Dewberry as part of a 2012 Virginia FEMA LiDAR project. The class-2 ground points were used to create a terrain surface with approximate point spacing of 2.5' (equal to the average spacing of the LiDAR class 2 ground points.) No thinning was done to the terrain surface. Using ArcGIS 3D Analyst tools, a 2' interval contour polyine feature class was derived from the terrain surface. Resulting contours were thin simplified, using ArcGIS tools, to remove extraneous vertices from the contours, and the contours were diced. This was done to increase efficiency in using the data for subsequesnt users.
