TAHOE ROAD RAPID ASSESSMENT METHODOLOGY (Tahoe Road RAM)

The Tahoe Road Rapid Assessment Methodology (Tahoe Road RAM) is a simple and repeatable field observation and data management tool that allows Tahoe Basin resource managers to assess and track the relative risk of paved roads to downstream water quality.

Tahoe Road RAM data entry and reporting can be grouped by areas of interest. An area can be an urban catchment, an entire jurisdiction, or a road network. Area delineation is not required to use Tahoe Road RAM to evaluate and track road segment conditions over time. Click to upload areas mapped in GIS.

Road class is a standardized mapping of road networks that are maintained by a Tahoe jurisdiction using similar presciptions (e.g., abrasive applications and pollutant recovery actions). Road class is used to spatially extrapolate discrete road segment RAM observations across all roads of corresponding class. Road class can only be uploaded within defined areas of interest. Click to upload road class mapped in GIS.

Road segments are discrete locations where RAM observations are conducted. Click to upload road segment location, ID and road class (if relevant) mapped in GIS.

Users conduct simple and standardized Tahoe Road RAM field observations at specific road segments to determine condition at time of observation. Condition is defined on a relative 0-5 scale. Click to enter Tahoe Road RAM observations.

View mapped and tabular road segment condition scores for past observation periods or graphical summaries of the variations in observed condition of specific road segments over time.
