Forest Uplands contribute less than 10% of the FSP loading, but more than a quarter of the total phosphorous loading to Lake Tahoe. Select Performance Measures (PMs) are tracked and reported based on the finding that the vast majority of the pollutant loading from undeveloped lands originates from paved and unpaved roads, disturbed areas and public facilities. As precipitation falling on these surfaces runs off, it picks up particles and nutrients. Unmitigated, these pollutants are deposited into nearby surface waters that drain to Lake Tahoe.
TMDL Performance Measure that tracks the number of public facilities in the Forested Uplands that are retrofitted with BMPs to reduce runoff volumes and remove fine sediment particles and nutrients contained therein. Public facilities are administrative and/or recreational facilities such as parking lots, trailheads, and buildings located on lands owned by TMDL Non-urban Implementing Partners. Maintenance includes repairs and/or improvements to existing stormwater retrofits as needed.
TMDL Performance Measure that tracks the total acres of forestlands with compacted soil, disturbed vegetation, and/or impacted hydrology that have been restored, enhanced, or mitigated each year. Disturbed areas are forestlands, other than roads and SEZs, in which soil, hydrologic function, and/or vegetation has been degraded by development, operations undertaken, or natural disturbance. Examples of disturbed areas include areas defined as soft coverage by TRPA, as well as ski runs, staging areas, and landings.
