Roadway and Shoreline Units
This indicator reporting category evaluates and rates scenic conditions of major roadways and views of the shoreline from the lake using two systems: travel route ratings to evaluate the travel experience, and scenic quality ratings which evaluate specific scenic resources (e.g., vistas of the lake, mountain peaks, etc.) seen from the travel unit. Roadway travel routes are separated into 54 separate roadway travel units and are assessed based on three categories that describe the dominant character of the travel route: natural, transitional, and urban. In addition to roadway routes, the lake's 72-mile shoreline is separated into 33 individual units, each representing a varying length of the shoreline that exhibits similar visual character when viewed from the lake. Each roadway unit and each shoreline unit is assessed using two scores, one for the quality of the travel experience and the other for the quality of specific scenic resources viewed from that unit. The TRPA Code of Ordinances, area plans, and the TRPA Design Review Guidelines, provide specific design standards and guidelines to ensure that redevelopment and development projects improve scenic quality and do not cause it to degrade.

The threshold evaluation assigns a status to an indicator relative to the adopted standard. As shown on the icon legend below, the background color of the reporting icon communicates the indicator “status” or estimate of current condition. For numerical standards, the status of an indicator is classified into “better” or “worse” categories based on the percent divergence of the current indicator value from the standard or interim target. For most indicators, the current value is taken directly from the value recorded in the most recent year. In some cases, the average value calculated from all data collected during the evaluation period is used. When an average value is used, it is noted and explained on the indicator evaluation page for that specific evaluation year.
Note: Thresholds reported as "Implemented" refer to thresholds that were adopted as policy guidance in the development of the Regional Plan. In these cases, the subject policies, ordinances, or environmental protections have been incorporated into the TRPA Regional Plan and TRPA Code of Ordinances.
