Coverage Mapping/Bathymetric Surveys/Best Management Practice (BMP) Plans
RCI consistently provides surveying and mapping services to businesses and residents of the Lake Tahoe Basin for the unique requirements associated with working and living in the sensitive environment surrounding Lake Tahoe. These services include coverage mapping, bathymetric surveys and BMP plans.
Coverage Mapping Required on all Exterior Improvements in the Tahoe Basin
Coverage mapping is required for any exterior improvements constructed on all properties within the Tahoe Basin. RCI’s mapping services conform with TRPA requirements and is required in all five jurisdictions within the Tahoe Basin: Carson City, Douglas, and Washoe Counties in Nevada, and Placer and El Dorado Counties in California. Coverage mapping depicts all impervious features on a given site, such as buildings, driveways, walkways, patios, and utilities. Typically, contours are shown to establish vertical relief and to assist the TRPA in determining land classifications which establish how much coverage, or new improvements, are allowed on a given site. Trees above 14” diameter at breast height are also shown, as they are also subject to permitting for removal by the TRPA.
Bathymetric surveys create relief maps of the lakebed. These are used for buoy permitting, water intake structures and for pier or breakwater improvements. The surveys are performed to comply with TRPA and the Nevada Division of State Lands (NDSL) requirements. RCI utilizes standard total station survey equipment on-shore coupled with our originally outfitted kayak. The kayak has a fixed height prism attachment for establishing position from the shore, and an on-board mounted depth finder to establish the elevation of the lake bed.
Best Management Practices (BMPs)
BMPs are prescribed procedures for minimizing storm water and snow melt run-off from properties. BMPs are required under TRPA regulations for all residential and commercial properties within the Tahoe Basin. Current regulations allow for individual property owners to prepare their own BMP plans through specifications and guidelines published on the internet. Some property owners, and commercial interests, often seek assistance from RCI in compiling these plans and specifications for their contractors or for their own personal use.
