Evidence of compacted and disturbed soil from vehicle traffic is shown above. Rainfall andsnowmelt will not infiltrate and instead becomes stormwater runoff causing erosion andcarrying sediment-laden water with it.Coverage:The TRPA defines LandCoverage as “A structure,improvement or covering shallnot be considered as landcoverage if it permits at least75 percent of normalprecipitation directly to reachthe ground and permits thegrowth of vegetation on theapproved species list.“OFF-PAVEMENT PARKINGIdentify all unpaved areas that exhibit signs of disturbance, primarily fromdriving and parking vehicles and/or heavy equipment. All areas used forparking and/or driving shall be paved in accordance with TRPA and localjurisdiction regulations. If a project has unpaved parking or vehicle trafficareas, work with TRPA or the local jurisdiction to bring that property intocompliance through either paving or restoring the area.All properties in the Lake Tahoe Region are subject to land coverageregulations that limit the amount of disturbance in the watershed. The landcapability and land coverage shall be verified prior to any changes in coverage(e.g. paving or restoring). Refer to Chapter 4, BMP Toolkit, Section 4.2.3 SoilStabilization (Non-Vegetative), and Chapter 7 Permitting for moreinformation.This unpaved driveway should be paved. It is currently a sediment source when vehiclestrack dirt onto the roadway and during disturbance from snow plows.CHAPTER 2: Site AnalysisTRPA BMP HandbookPage 2-6 2012
