It is broken down by '25 - 50%', and 'greater than 50%' slope categories for all unincorporated areas.Below is a description of the source Digital Elevation Model and Slope that went into creating this dataset.Digital Elevation Model / LAR-IAC 7:This 1 meter Digital Elevation Model (DEM) is a model of surface elevation in the County of Los Angeles developed by the Los Angeles Regional Imagery Consortium (LAR-IAC). The LAR-IAC project encompasses the entire land area of Los Angeles County in mainland plus Catalina Island. The Area of Digital Elevation Model data developed over the Urban/Suburban area mainland covers approximately 4214 square miles. Tiles were downloaded in September, 2025 from the USGS National Map: https://apps.nationalmap.gov/lidar-explorer/#/. This dataset was re-projected from the original NAD83, UTM Zone 11N projection to State Plan, CA Zone V. The grid size is 3.28 x 3.28 feet to be equivalent to 1 meter.Detailed product information (including accuracy report) is contained in the LAR-IAC7 Product Guide.We highly recommend that you visit the LAR-IAC Project Website to find a rich source of information about the data and the LAR-IAC program. The site includes project documents, full FGDC compliant metadata, data downloads of related GIS used to complete the project, sub-licensing information, sample imagery and data, and information about this acquisition.GIS Data showing flight-date information is available from the LAR-IAC Project website site, and elsewhere in the LA County GIS Data PortalUpdate History:10/30/25 - Loaded into SDE and replaced the former version of Hillside Management that was generated in 2006.", "geometryType": null, "copyrightText": "Los Angeles Region Imagery Acquisition Consortium (LAR-IAC), Pictometry International Corp", "parentLayer": null, "subLayers": [], "minScale": 0, "maxScale": 0, "defaultVisibility": true, "extent": { "xmin": 6275455.466297407, "ymin": 1385705.440766645, "xmax": 6668532.107964073, "ymax": 2122137.6949333106, "spatialReference": { "wkid": 102645, "latestWkid": 2229, "xyTolerance": 0.003280833333333333, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -117608900, "falseY": -91881400, "xyUnits": 3048.0060960121928, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeNone", "displayField": "Value", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null }, { "name": "Value", "type": "esriFieldTypeInteger", "alias": "Value", "domain": null }, { "name": "Count_", "type": "esriFieldTypeDouble", "alias": "Count_", "domain": null } ], "geometryField": {}, "indexes": [ { "name": "R75_SDE_ROWID_UK", "fields": "OBJECTID", "isAscending": true, "isUnique": true, "description": "" } ], "subtypes": [], "relationships": [], "canModifyLayer": false, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Query,Map", "supportsStatistics": false, "supportsExceedsLimitStatistics": false, "supportsAdvancedQueries": false, "supportedQueryFormats": "JSON, geoJSON, PBF", "isDataVersioned": false, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": false, "supportsPercentileStatistics": false, "supportsHavingClause": false, "supportsOrderBy": false, "supportsDistinct": false, "supportsCountDistinct": false, "supportsPagination": false, "supportsLod": false, "supportsQueryWithLodSR": false, "supportsTrueCurve": true, "supportsQueryWithDatumTransformation": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": false, "supportsTimeRelation": true, "supportsSqlFormat": false, "supportsQueryAnalytic": false }, "supportsDatumTransformation": true, "dateFieldsTimeReference": null, "preferredTimeReference": null, "datesInUnknownTimezone": false, "hasMetadata": true, "isDataArchived": false, "archivingInfo": { "supportsQueryWithHistoricMoment": false, "startArchivingMoment": -1 }, "supportsCoordinatesQuantization": true, "supportsDynamicLegends": true }
