The scenic quality of the built environment (e.g. houses, commercial buildings, etc.) is guided by a threshold policy standard referred to as "community design." Design standards and guidelines apply to new, redeveloped, or remodeled buildings. As a result, progress is made toward implementing the community design threshold standard as more development and redevelopment projects occur and replace legacy development that has become inconsistent with current design standards and guidelines. Design standards and guidelines are sensitive to the context in which they are applied. In more natural areas, design standards and guidelines focus on minimizing the visibility of development to reduce distractions from the natural scenery. In more developed areas, design standards and guidelines seek to achieve visual interest and be consistent with the desired character of the individual community in which they are located, as well as promote design that blends with the natural environment. The TRPA Design Review Guidelines, Code of Ordinances, and area plans all include design provisions.
