Airport noise contours for the existing conditions (2014) for Marina Municipal Airport and Monterey Regional Airport were developed using the FAA's Integrated Noise Model (INM), using assumptions provided in the Monterey and Marina Airport Land Use Computability Plans prepared by Coffman Associates, Inc. and adopted by Monterey County on February 25, 2019 and May 30, 2019. <\/span><\/p>

Output data selected for calculation by the INM are annual average noise contours in CNEL. The 60, 65, 70 and 75 CNEL noise contours were mapped for this analysis. <\/span><\/p><\/div><\/div><\/div>", "hasVersionedData": true, "hasArchivedData": true, "hasBranchVersionedData": false, "supportsDisconnectedEditing": true, "supportsDatumTransformation": true, "supportsReturnServiceEditsOption": true, "returnServiceEditsHaveSR": true, "supportsQueryDataElements": true, "datesInUnknownTimezone": false, "supportsRelationshipsResource": true, "syncEnabled": false, "supportedExportFormats": "sqlite,filegdb,shapefile,csv,geojson", "extractChangesCapabilities": { "supportsReturnIdsOnly": false, "supportsReturnExtentOnly": false, "supportsReturnAttachments": false, "supportsLayerQueries": false, "supportsGeometry": false, "supportsFeatureReturn": false, "supportsReturnHasGeometryUpdates": false, "supportsFieldsToCompare": false, "supportsServerGens": false }, "supportedQueryFormats": "JSON", "maxRecordCount": 2000, "maxRecordCountFactor": 1, "capabilities": "Query,Create,Update,Delete,Uploads,Editing", "description": "", "copyrightText": "Monterey County RMA; Coffman Associates, Inc.", "advancedEditingCapabilities": { "supportsSplit": true, "supportsReturnServiceEditsInSourceSR": true, "supportsAsyncApplyEdits": true, "supportsApplyEditsbyUploadID": true, "supportedApplyEditsUploadIDFormats": "JSON", "supportsMultipatchOptionForServiceEdits": true, "supportedApplyEditsOptions": {"supportedEditingOptions": 0} }, "spatialReference": { "wkid": 102644, "latestWkid": 2228, "xyTolerance": 0.003280833333333333, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -116466200, "falseY": -92735300, "xyUnits": 3048.0060960121928, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 }, "initialExtent": { "xmin": 5690133.250874453, "ymin": 2073372.696316194, "xmax": 5793731.679802681, "ymax": 2174649.934030228, "spatialReference": { "wkid": 102644, "latestWkid": 2228, "xyTolerance": 0.003280833333333333, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -116466200, "falseY": -92735300, "xyUnits": 3048.0060960121928, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "fullExtent": { "xmin": 5720613.462750003, "ymin": 2106364.544750005, "xmax": 5805867.696500003, "ymax": 2145761.3170000017, "spatialReference": { "wkid": 102644, "latestWkid": 2228, "xyTolerance": 0.003280833333333333, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -116466200, "falseY": -92735300, "xyUnits": 3048.0060960121928, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "allowGeometryUpdates": true, "allowTrueCurvesUpdates": false, "onlyAllowTrueCurveUpdatesByTrueCurveClients": false, "supportsApplyEditsWithGlobalIds": false, "supportsTrueCurve": true, "units": "esriFeet", "documentInfo": { "Title": "Map", "Author": "", "Comments": "", "Subject": "", "Category": "", "Keywords": "Airport,Noise,Contours,Land Use,Marina,Monterey" }, "supportsQueryDomains": true, "supportsQueryContingentValues": true, "layers": [ { "id": 0, "name": "Airport_Noise_Contours_Existing", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 5000000, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolyline" } ], "tables": [], "relationships": [], "enableZDefaults": false, "allowUpdateWithoutMValues": false, "supportsVCSProjection": true, "datumTransformations": [ { "geoTransforms": [ { "wkid": 108190, "latestWkid": 108190, "transformForward": true, "name": "WGS_1984_(ITRF00)_To_NAD_1983" } ] }, { "geoTransforms": [ { "wkid": 108190, "latestWkid": 108190, "transformForward": false, "name": "WGS_1984_(ITRF00)_To_NAD_1983" } ] } ], "referenceScale": 0, "serviceItemId": "70394710bccc4386ac602628ec1b37a4" }
