TRPA Revegetation Plan TemplateSoil restoration and revegetation activities required as part of a Project’s permitted conditionsmust submit a complete TRPA Revegetation Plan:A. SITE DESCRIPTIONInformation needed includes location, land capability, site conditions such as soil type andinfiltration rate, vegetation types, extent of sun and shade, presence of sensitive areas such asstream environment zones or backshore, and relevant site characteristics such as rockoutcroppings.Project Address:Assessor’s Parcel Number (APN):NRCS Soil Map Unit: Max depth of Install: Ksat (in/hr):Land Capability:TRPA Permit Number:Detailed Site Description:B. PROJECT DESCRIPTION, GOALS, AND OBJECTIVESThis section describes the reasons why the revegetation project is being undertaken and what theproject will achieve. Project goals and objectives should directly relate to the problem the projectis intended to address, and depict issues that will continue or result if the project is notimplemented. These goals will guide the selection of success criteria. While the BMP handbookgenerally focuses on revegetation for the purposes of erosion control, other project goals andobjectives include restoring vegetative diversity, creating wildlife habitat, fulfilling scenic screeningrequirements, and providing water quality treatment.C. PROJECT SCHEDULEProvide a detailed schedule for each element of the plan. The schedule will depend on thecomplexity and scale of the project, but at a minimum will typically include dates for temporaryBMP installation, pre-grade inspection, topsoil salvage, soil loosening and amendments, seeding,planting, irrigation, weeding, removal of irrigation system, final inspection, etc.D. SELECTION OF PLANT MATERIALSUse the description of common Revegetation Site Types, Site Type Recommended Species List,Site Type Recommended Seed Mixes, and TRPA Approved Plant Species Attributes Table toguide the plant selection process for any Lake Tahoe Region revegetation project. Once selected,list plant materials in the plant materials table. Plant materials selected must be robust, free ofdisease and insect infestation, and have vigorous foliage and wood. Plants should be from areputable nursery and grown locally or in a similar climate. Seeds should be approved for purity,germination, and be weed free.TRPA BMP HandbookCHAPTER 5: Soil and Vegetation Management2012 TRPA Revegetation Plan TemplatePage 1
