Lots are specific pieces of land within a platted subdivision and are assigned unique numbers. Data maintained by the Douglas County Assessor staff

The parcels layer displays property boundaries and contains ownership information. Parcels data is updated weekly and is maintained by the Douglas County, KS Information Technology Department GIS Division. Parcel boundaries are a representation of ownership and are not suitable for marking property boundaries.

Douglas County NV Community Development: Future Land Use

Platted subdivisions are tracts of land that have been legally divided into smaller lots, blocks, and streets, with a recorded map (plat) showing these divisions, for the purpose of building developments or sale. Data maintained by DC Assessor staff

Blocks are groups of lots that are usually bounded by streets or other significant physical boundaries within a platted subdivision. Modern subdivisions only use Lot numbers with unique lot numbers. When blocks were used, only the blocks had unique numbers...lots could reuse 1-10, or however many lots were in a block. Ex. Lot 1 Block 1, or Lot 1 Block 2, etc...Maintained by the DC Assessor's staff

Infrastructure, such as roads, airports, water and energy transmission and distribution facilities, sewage treatment plants, and many other facilities, is vital to the sustainability and vitality of any populated area. Rehabilitation of existing and development of new infrastructure requires three natural resources: natural aggregate (stone, sand, and gravel), water, and energy http://rockyweb.cr.usgs.gov/frontrange/overview.htm.

The principal goals of the U.S. Geological Survey (USGS) Front Range Infrastructure Resources Project (FRIRP) were to develop information, define tools, and demonstrate ways to: (1) implement a multidisciplinary evaluation of the distribution and quality of a region's infrastructure resources, (2) identify issues that may affect availability of resources, and (3) work with cooperators to provide decision makers with tools to evaluate alternatives to enhance decision-making. Geographic integration of data (geospatial databases) can provide an interactive tool to facilitate decision-making by stakeholders http://rockyweb.cr.usgs.gov/frontrange/overview.htm.

DOUGLAS COUNTY SURVEY/GISGIS PARCEL MAPPING GUIDELINES FOR PARCEL DISCREPANCIESIt is the intent of the Douglas County GIS Parcel Mapping to accurately identify the areas of land parcels to be valued and taxed 1. Discrepancies in areas• The Auditor/Assessor (tax) acreage areas started with the original US General Land Office (GLO) township plat maps created from the Public Land Survey (PLS) that was done between 1858 and 1871. The recovery of the PLS corners and the accurate location of these corners with GPS obtained coordinates has allowed for accurate section subdivisions, which results in accurate areas for parcels based on legal descriptions, which may be significantly different than the original areas. (See Example 2)• Any parcel bordering a meandered lake and/or a water boundary will likely have a disparity of area between the Auditor/Assessor acreages and the GIS acreages because of the inaccuracy of the original GLO meander lines from which the original areas were determined. Water lines are not able to be drafted to the same accuracy as the normal parcel lines. The water lines are usually just sketched on a survey and their dimensions are not generally given on a land record. The water boundaries of our GIS parcels are located from aerial photography. This is a subjective determination based on the interpretation by the Survey/GIS technician of what is water. Some lakes fluctuate significantly and the areas of all parcels bordering water are subject to constant change. In these cases the ordinary high water line (OHW) is attempted to be identified. Use of 2-foot contours will be made, if available. (See Example 1)• Some land records do not accurately report the area described in the land description and the description area is ignored. (See Example 3)• The parcel mapping has made every attempt to map the parcels based on available survey information as surveyed and located on the ground. This may conflict with some record legal descriptions.Solutions• If an actual survey by a licensed Land Surveyor is available, it will be utilized for the tax acreage.• If the Auditor/Assessor finds a discrepancy between the tax and GIS areas, they will request a review by the County Survey/GIS department.• As a starting guideline, the County Survey/GIS department will identify all parcels that differ in tax area versus GIS parcel area of 10 % or more and a difference of at least 5 acres. (This could be expanded later after the initial review.)• Each of these identified parcels will be reviewed individually by the County Survey/GIS department to determine the reason for the discrepancy and a recommendation will be made by the County Survey/GIS department to the Auditor/Assessor if the change should be made or not.• If a change is to be made to the tax area, a letter will be sent to the taxpayer informing them that their area will be changed during the next tax cycle, which could affect their property valuation. This letter will originate from the Auditor/Assessor with explanation from the County Survey/GIS department. 2. Gaps and Overlaps• Land descriptions for adjoining parcels sometimes overlap or leave a gap between them.o In these instances the Survey/GIS technician has to make a decision where to place this boundary. A number of circumstances are reviewed to facilitate this decision as these dilemmas are usually decided on a case by case basis. All effort will be made to not leave a gap, but sometimes this is not possible and the gap will be shown with “unknown” ownership. (Note: The County does not have the authority to change boundaries!)o Some of the circumstances reviewed are: Which parcel had the initial legal description? Does the physical occupation of the parcel line as shown on the air photo more closely fit one of the described parcels? Interpretation of the intent of the legal description. Is the legal description surveyable?Note: These overlaps will be shown on the GIS map with a dashed “survey line” and accompanying text for the line not used for the parcel boundary. 3. Parcel lines that do not match location of buildings Structures on parcels do not always lie within the boundaries of the parcel. This may be a circumstance of building without the benefit of a survey or of misinterpreting these boundaries. The parcel lines should be shown accurately as surveyed and/or described regardless of the location of structures on the ground. NOTE: The GIS mapping is not a survey, but is an interpretation of parcel boundaries predicated upon resources available to the County Survey/GIS department.Gary Stevenson Page 1 7/21/2017Example 1Example 2A Example 2B Example 3

This dataset is a representation of the boundaries of the original claims (or water-righted areas) sourced from the Carson River and tributaries, as identified by the U.S. District Court in the Alpine Decree of 1980. The intended use of these data is to assist in identifying the general locations of the water-righted areas, the associated claim number, and the source map produced by the Nevada Division of Water Resources (NDWR) and the Federal Water Master during the Carson River Appurtenance Mapping Project. This mapping project was initiated in mid-1990s and continued into the early 2000's, with the final results being a series of maps identifying the location, size, and associated parcels of each claim of the Alpine Decree, signed by the State Engineer and Federal Water Master. These maps are available on the NDWR website: https://water.nv.gov/RiverMapSearch.aspx. This GIS layer should not be considered a replacement of the signed maps and exists only as guide and starting point to identify the approximate locations of the water-righted areas in comparison to modern parcel boundaries. Further research is required to determine if a particular parcel originally had decreed water rights and has retained those rights. Please contact the Division of Water Resources for more information.In order to produce a GIS depiction of the claims, the final signed maps were georeferenced to the most up-to-date version of the Douglas County and Carson City parcel datasets. Each claim and associated dry area was then digitized from the boundaries shown on the georeferenced map and attributed with the assigned claim number, a link to the claim on the NDWR Permit Database, the source map number, and a direct link the source map on the NDWR website. As this layer is strictly a visual representation, no attempt was made to match the acreages listed on the source map or in the decree for each claim.The information in this GIS layer is derived by interpretations of georeferenced maps and is being provided for convenience only. Please refer to the actual decree documentation as such records may differ from the information provided herein.
