The goal of TRPA GIS is to maintain and promote the use of a regional geographic data warehouse for the Tahoe Basin and to assist in the development of shared geographic data and automated systems which use that data. GIS is the industry standard for mapping geographic information and this tool allows for broader integration and comparison, improved analysis, and multilayer functionality. The use of GIS helps TRPA use the best information for planning and monitoring. TRPA has established standard operating procedures to outline standards for the delivery of consistent, standardized GIS data, maps, data analysis, and tools. TRPA is continually improving the GIS resources and tools.

|Tahoe Best Management Practices (BMP) Map Viewer
This map allows users to search by address or part of the address or by APN to gain BMP Status information which can be exported to Excel. Click here to also view an interactive map that displays BMP Certificates issued by year.
|Active Transportation Map
This tool allows users to view existing and proposed bike routes, dirt trails, special assessment districts, and their buffers. Users can zoom to an address or an APN and determine if their project is within 75 feet of a proposed or existing bicycle or pedestrian route. Refer to the legend for more detail on the type of facility that exists or is proposed.
|Shoreline Plan Map
This map provides a current inventory of Lake Tahoe shoreline structures, natural features, and environmental constraints. This information is provided to inform the Shoreline Planning Initiative. A Shoreline Plan Map Tutorial includes directions for using the map and a description of layers.
|Plan Area Statements Map Viewer
This interactive map provides the location and plan document associated with adopted Area Plans, Community Plans (CP), and Plan Area Statements (PAS) and it provides estimates on whether the land is sensitive or not sensitive (not field verified).

This map provides data to help inform stakeholders about the existing conditions for traffic, land use, transportation services, and other conditions in Lake Tahoe’s major transportation corridors.
|The Environmental Improvement Project (EIP) Tracker Map
shows the approximate locations of EIP projects, which you can color-code in few different ways. Locations are approximate, and for large projects are simplified to a single point even though the project may have multiple locations.
