Percent of Land Coverage Within Land Capability Class 1a (allow up to 1% impervious coverage)

Lands classified as 1a are among the most sensitive in the Tahoe Region and can support the least amount of land disturbance. The percent of land coverage within land capability class 1a indicator measures the percent of land coverage on class 1a lands in the Tahoe Region. The indicator allows up to one percent impervious coverage within land capability class 1a.  Land capability class 1a generally includes natural areas, including steep mountainous terrain with shallow soils. These environmentally sensitive areas, with slopes exceeding 30 percent, are not generally suitable for intensive development, but class 1a areas support wildlife and dispersed recreation.  

Status

Percent cover in each Bailey land capability class relative to the allowable coverage in class.

Applicable Standard

SC1: Impervious cover shall comply with the "Land Capability Classification of the Lake Tahoe Basin, California-Nevada, A Guide for Planning", Bailey, 1974. Allowable percent of impervious cover in Land Capability subclass 1a - 1%.

Key Points

  • Impervious coverage within class 1a was estimated to be 211 acres, less than the threshold standard of 240 acres.
  • Projects to acquire and/or restore sensitive lands add to the natural function of the Region's ecosystem. The acquisition and restoration of sensitive lands protect watersheds by mitigating the effects of development, providing valuable habitat for special status species, and enhancing recreational opportunities in the Tahoe Region.
  • More than 215 acres of sensitive lands (land capability classes 1-3) were acquired between 2016 and 2019 by Environmental Improvement Program partners.

Delivering and Measuring Success

EIP Indicators

  • Acres of Environmentally Sensitive Land Acquired

    Since 2007, EIP partners have aquired over 1,150 acres of environmentally sensitive land for protection or restoration.

  • Impervious Coverage Retired

    Between 2016 and 2019, EIP partners and private partners through projects retired (i.e., permanently remove from future use) 3,909 square feet (0.1 acres) of Class 1a coverage.
