Significant Lands - Waterbodies

The State Lands Commission has prepared the Significant Lands Inventory (report) for the California Legislature as a general identification and classification of those unconveyed State school lands and tide and submerged lands which possess significant environmental values. The publication incorporates evaluated and pertinent comments received on the initial draft report which was circulated statewide in February 1975.The absence of a particular digitized waterway in the dataset does not mean that the State does not claim ownership of that parcel or waterway, or that such specific parcel or waterway has no significant environmental values. This dataset is not intended to establish ownership, only to identify those parcels which possess significant environmental values. Staff was unable to physically inventory all of the considered lands; instead, the advice and participation of those with known environmental expertise was utilized as additional to staff survey. * Tide and submerged lands are digitized in the WaterBody and WaterLine feature classes; WaterLines for coastal areas, WaterBody for inland areas. Tide and submerged lands under the jurisdiction of the State Lands Commission are those sovereign lands received from the Federal Government by virtue of California's admission to the Union on an equal footing with the original States. Such lands, and State interest therein, are generally the lands waterward of the ordinary high water mark of the Pacific Ocean (seaward to a three-mile limit); tidal bays, sloughs, estuaries; and, navigable lakes and streams within the State. * School Lands are digitized in the SchoolLand feature class. State school lands under the jurisdiction of the Commission are largely composed of the 16th and 36th sections of each township. The Federal Government transferred these lands to the State in 1853, in order to establish a financial foundation for a public school system. In cases where the 16th and 36th sections were mineral in character, incomplete as to acreage total, or already claimed or granted by the Federal Government, the State was permitted to select other lands "in lieu" of the specific sections. The public trust of commerce, navigation and fisheries which the State retains on patented sovereign lands should also be considered included in this inventory. Wherever a waterway, or body of water, is listed or mapped, the common trust state interest in patented sovereign lands, if any, is also included. The State Lands Commission emphasized when it adopted this report at its December 1, 1975 meeting that all tide and submerged lands are significant by the nature of their public ownership. Only because of the methodology used for this report are all of these waterways not specifically listed in this inventory. It is the intent of the State Lands Commission that the Significant Lands Inventory be periodically updated. This dataset should be considered informational, to assist the Legislature, the Commission, and the public in considering the environmental aspects of a proposed project and the significant values to be protected therein.

Eelgrass - R7 - CDFW [ds1503]

Zostera marina, or eelgrass, grows intertidally and in the shallow subtidal of estuaries, bays, and other protected coastal areas of the ecoregion. It is a flowering plant, not an alga, and often occurs in dense beds. It helps prevent erosion and maintain stability near shore by anchoring sediment with its spreading rhizomes and slowing water flow. Eelgrass beds also provide foraging, breeding, and nursery areas for many species of invertebrates, fish, and birds. This file aggregates data from many sources across multiple years; see supplemental info.

CA State Lands Commission Leases

The California State Lands Commission (CSLC) may issue leases or permits on state lands under its jurisdiction. Additional information regarding CSLC leasing can be found at: [https://www.slc.ca.gov/leases-permits/]. This is a point feature dataset indicating the approximate locations, often represented by a center point, of the general lease area of lands leased by the CSLC on state sovereign lands and school lands, including coastal marine areas, bays, rivers, and lakes. This dataset is to be considered incomplete as new leases are being entered into the CSLC database, and existing leases are modified or terminated, on an ongoing basis. Many marine areas, bays, rivers, and lakes are not under the leasing jurisdiction of the CSLC because they have been legislatively granted in trust to other government entities. Additionally, some leases are not shown at all for a variety of reasons. Many point features in this dataset provide links to maps and/or land descriptions used in the CSLC lease approval process. These documents are hosted on the CSLC archives website at [https://www.slc.ca.gov/archives/]. In some cases, these documents provide reliable, current lease boundary information, while in other cases, additional information is necessary to properly define lease boundaries. Additionally, revisions to lease boundaries may have occurred subsequent to CSLC approval, as in the case of as-built locations that differ from originally approved alignments. Further, the boundary of some leases may be the mean high tide line, which in a state of nature is both ambulatory, and in the absence of a survey conducted by a licensed land surveyor, not readily locatable. Disclaimer of Liability This dataset is not suitable for any legal purpose. The CSLC makes no warranty of any kind, express or implied, nor assumes any legal liability or responsibility for the accuracy, completeness, or usefulness of any of the information contained in the dataset. The CSLC assumes no legal liability or responsibility for anyone's use of the information.

MAIN - AB 1236 Compliance Status

The “EV Charging Station Permit Streamlining Map” (EVCS Streamlining Map) is a living companion to the [2023 Electric Vehicle Charging Station Permitting Guidebook]. Its purpose is to create a shared, understanding of EVCS permit streamlining across the state, and track compliance with California laws [AB 1236 (2015)] and [AB 970 (2021)].
Vegetation - Manzanar National Historic Site [ds3129]

The NPS Vegetation Inventory Program goals are, among others, to consistently map and document the vegetation of all National Park Service units with a resource component, thereby creating a baseline vegetation inventory. Based on these decisions the final vegetation inventory project boundary covered 330-hectares (814-acres) consisting of the MANZ boundary as it existed in 2005. All plant community data that could be interpreted from the 2010 NAIP Ortho Photography for Inyo County, California - Manzanar Quadrangle were digitized in accordance with the minimum mapping unit (MMU) of 1/2 hectare. This included selected features that fell into the National Vegetation Classification and the Anderson Level II land use classification. Some classes below the MMU were included, especially water and wetland features, weed patches, and those at the edge of the study area (i.e. cut off by other features and borders). Managed roads (to visible right-of-way or fence line) and streams/drainages wider than 10 meters were digitized as polygons and attributed accordingly. Polygons were checked in the field and attributed accordingly. The final MANZ spatial database and map layer was produced by CTI from 2010 imagery using 21 map units that were directly cross-walked or matched to their corresponding rUSNVC plant association/alliance or land cover types (FGDC 2008). Maps and other spatial data products for parks in the Continental United States are normally produced in Universal Transverse Mercator (UTM) projection, North America 1983 (NAD 83) datum, use meters for map and distance units, and have a nominal 1:24,000-scale with a minimum mapping unit (MMU) of 0.5 hectare (1.2 acres). The vegetation maps must meet the National Map Accuracy Standards for positional accuracy (TNC and ESRI 1994a & Lea and Curtis 2010), and the recently revised minimum map class accuracy goal across all vegetation and land cover classes of 60% percent at the finest scale (formerly 80%, NPS 2009).The final map layer was assessed for thematic accuracy by creating contingency tables and the final overall accuracy of the map layer was determined to be 96% with a Kappa value of 95%. More information can be found in the project report, which is bundled with the vegetation map published for BIOS here: [https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/3100_3199/ds3129.zip]
Bottlenecks

Bottleneck Mapping is a subproject of the Mobility Performance Report, which is one of the products of the Mobility Performance Reporting and Analysis Program (MPRAP). The Mobility Performance Report is prepared by the California Department of Transportation (Caltrans) and District staff to provide detailed data about highway system performance related to congestion and mobility. Caltrans collects vehicle counts and calculates speeds at all hours of the day and all days of the week in major metropolitan areas throughout California via the Caltrans Performance Measurement System (PeMS--see Data Source tab). This information helps identify congestion bottlenecks and results in more cost-effective investments to improve the performance of the State Highway System.
Mule Deer Migration Lines - Modoc Interstate CA and OR - 1999-2001, 2017-2020 [ds2893]

The project leads for the collection of this data were Julie Garcia and Richard Shinn. Female mule deer were captured in February 2017 and equipped with satellite collars manufactured by Lotek, which collected GPS data to June 2020. Additional GPS data was collected from deer in 1999-2001 and included in the analysis to supplement the small sample size of the 2017-2020 dataset. The data was collected from deer throughout Modoc County with a priority to ascertain general distributions, survival, and home range and not to model migration routes, hence the low sample sizes in specific winter ranges. The Modoc Interstate deer herd migrates from a winter range near Clear Lake Reservoir in Modoc County, California north into Oregon in Klamath and Lake counties for the summer. GPS locations were fixed at 12-hour intervals in the 2017-2020 dataset and 8-hour intervals in the 1999-2001 dataset. Migration lines as symbolized connect GPS data points per deer per seasonal migration. GPS points were extracted only during migrations using net-squared displacement graphs. Sixteen migration sequences from 12 deer, with an average migration time of 23.89 days and an average migration distance of 69.71 km, were obtained from the 1999-2001 dataset. Thirty-six migration sequences from 9 deer, with an average migration time of 19.53 days and an average migration distance of 87.57 km, were obtained from the 2017-2020 dataset.
