and shorezone management. 6 Although the CEM addresses a broad set ofapplications, the sections used for this chapter have been interpreted andadapted to address the specific mission, permitting authority, and projectoperations of the Tahoe Regional Planning Agency (TRPA). Note that TRPAstill requires findings be made that a project is consistent with the TRPARegional Plan, including all applicable Goals and Policies, plan area statementsand maps, the Code of Ordinances and other TRPA plans and programs.Immediate and long-term beneficial and adverse impacts to project areas andadjacent environments are summarized along with methods to model designparameters and guidance on formulating and planning studies that supportshorezone protection and navigation improvement projects. Construction andpollution prevention BMPs are also included.8.1.1 APPLICABILITYThe CEM is applicable to those USACE jurisdictions having civil and capitalworks responsibility in coastal and lake shore settings of the United States. It isanticipated that the comprehensive scope of this manual will warrant its use byregional planners, civil engineers, and environmental scientists who work inthe shorezone environment of Lake Tahoe. Although, the CEM is applicableto a broad set of applications the sections used for the Shorezone ProtectiveStructures and BMPs chapter have been interpreted and adapted to address thespecific mission, permitting authority, and project operations of the TRPA.8.1.2 PURPOSEThe BMPs cited in this chapter include various static and dynamic featuresspecifically designed to match the dominant physical processes associated withthe eight distinct geomorphic settings identified in Lake Tahoe.One of the purposes of this chapter is to provide insight and technical advice toencourage the consideration and incorporation of soft engineering intoshoreline stabilization or development projects whenever possible.8.1.3 SCOPESelection of the best environmental and engineering solution to a specificshorezone problem requires a systematic and thorough study of the setting.This is often required due to the complex nature of shorezone projects and thegeomorphic diversity of shorezone environments. The prerequisite to suchstudies, or initial analysis, requires formulating a clear definition of theproblem and its probable causes. Once accomplished, a comprehensive reviewof potential solutions and alternatives can be generated. This chapter addressesboth natural and human-induced alterations in the shorezone; it provides6USACE, 1989, EM 1110-2 -5025, Environmental Engineering for Coastal Shore Protection, andUSACE, 2008, Coastal Engineering Manual - Parts I-6CHAPTER 8: Shorezone Protective Structures and BMPsTRPA BMP HandbookPage 8-2 2012
