Fire Hazard Severity Zones (FHSZ) Fire Hazard Severity Zone classes from the map dated September 29, 2023, as adopted on January 31, 2024 and implemented on April 1, 2024 This layer was acquired/downloaded from the CalFire OSFM. Below is the original metadata that came with the layer:   The State Fire Marshal shall classify lands within state responsibility areas into fire hazard severity zones. Each zone shall embrace relatively homogeneous lands and shall be based on fuel loading, slope, fire weather, and other relevant factors present, including areas where winds have been identified by the department as a major cause of wildfire spread.  The California laws and regulations that require Fire Hazard Severity Zones include California Public Resource code 4201-4204 and California Code of Regulations Title 19, Section 2201.  Effective April 1, 2024 this regulatory adoption repeals Section 1280.1 of Title 14 California Code of Regulations and adopts similar regulatory provisions in Section 2201 of Title 19 California Code of Regulations.   A prior version of this file and data was released as part of the data package accompanying the final Public Comment period for Fire Hazard Severity Zones (September 29, 2023).  This previous version and this version are the same geographic representation of Fire Hazard Severity Zones and are now part of the formal regulation as adopted. While under normal workflow any revision to a public data file would get reflected in the filename, in this case the file name remains identical as it is part of the adopted regulation.  The only changes reflect edits to the metadata describing timing of adoption and effective date for the regulation.   Calistoga Revisions (2025) Revisions were made within Calistoga city limits by request of Calistoga City Fire (Jed Matcham). Fire Hazard Severity Zones were expanded to cover all parcels they intersect. Each parcel was assigned the highest severity zone it overlapped with.  Steps taken to update Fire Hazard Severity Zones within Calistoga Fire Hazard Severity Zones within Calistoga City Limits were erased from the original layer downloaded from Calfire.  Join Calistoga Parcels with original FHSZ layer by spatial intersect. If parcel intersects with multiple FHSZs, duplicate parcels with different FHSZ zones exist. Per parcel, only keep parcel with highest severity Dissolve parcel polygons from Calistoga_FHSZ by severity zone. This will combine features that have the same severity zone.  Clip ROW FHSZ Zones within Calistoga (They will be appended back in later). This is done so when I append them to the FHSZ_Erase layer, all polygons within Calistoga end at the city boundaries.   Append Calistoga_FHSZ_Dissolve polygon layer and Calistoga_ROW_Clipped to FHSZ_Erased layer. Merge ROW polygons of the same Fire Hazard Severity Class with Parcel Polygons of the same Fire Hazard Severity Class where they are adjacent.  Cleaned up the SRA / LRA divide to follow the Calistoga City Limits in North central Part of town

Site Regions and Site Districts of Ontario represent an early Ecological Land Classification (ELC) system originally developed by Angus Hills. This dataset was revised by the ELC Working Group in 2000 to better reflect new information and new technology. The Site Regions of Ontario was used for descriptive, planning, and resource management purposes. This upper level in its hierarchy was most useful for provincial and regional roll-ups of data and for strategic planning. Site Districts of Ontario is a more detailed lower (finer-scale) level of the hierarchy, and was more useful for detailed resource management prescriptions and other local and site planning applications. This layer is designed to be used as a spatial selection tool and as a background layer suitable for overlay and or intersection with numerous scales or current hydrologic data.

Miscellaneous events are often the result of the cumulative impact of a combination of abiotic, insect and disease agents or events.  For example, Aspen decline where repeated infestations of Forest Tent Caterpillar, are combined with several seasons of prolonged drought. The Government of Ontario tracks forest damage events to help proactively manage the detrimental effects to our forests.   We monitor the threat and spread of invasive forest pest insect species in Ontario. The data is also important to the Forest Management Planning process in calculating timber volume loss within affected areas.

This must be taken into account when comparing information from this data class to other NRVIS layers that have a higher spatial accuracy (e.g.:Forest Cover). Otherwise, misleading results will be derived whenever this information is subjected to analysis. This NRVIS data class accommodates history for events spanning several years which includes overlaps. Users should request and/or sort out individual events through the 'Year of Event' ,'Event Name' and 'Forest Damage Ranking' attributes in order to prevent clutter.

The National Flood Hazard Layer (NFHL) dataset represents the current effective flood risk data for those parts of the country where maps have been modernized by the Federal Emergency Management Agency (FEMA). The data in this service was published by FEMA as of July 18, 2025 (Latest Study Effective Date = 07/08/2025; Latest LOMR Effective Date = 07/09/2025). Also see the Feature Service and Tile service.

A derived spatial layer generated from research plot source data identifying features and attributes with active temporal protection requirements within a designated management area or polygon. The spatial features and attributes in this layer are sourced from the following data classes: Research Point (RESPOINT) Research Line (RESLINE) Research Poly (RESPOLY) The temporal constraint assesses the active status of source features and facilitates automated lifecycle management of the features included in this derived layer. Temporal constraint PROTECTION_END_DATE is greater than the date this layer was generated. The spatial extents of features in this derived layer are based on source feature extents, to which specified buffer distances has been added. Applied buffer PROTECTION_BUFFER_DIST field value (meters).  This layer is regenerated at scheduled intervals, with the previous version of this layer archived and replaced by the newly generated version.  Status:  On going: data is continually being updated Maintenance and Update Frequency: As required  Contact Calvin Julie, Natural Resources Information Unitcalvin.julie@ontario.ca Note Additional features licensed under the Ontario Geospatial Data Exchange (OGDE) Agreement are available to members of the OGDE for professional, non-commercial use only.
