All activities and development in all zone districts shall comply with all applicable standards in this Chapter 7, unless the text of this Chapter 7 or some other portion of this Land Use Code provides an exemption. Some provisions specifically related to the avoidance of environmental hazards only apply within mapped areas designated on Pitkin County’s adopted constraint maps, or in unmapped areas known to fall within the definition of Areas of Local and State Interest as implemented by Pitkin County. The standards in this Chapter 7 specifically apply not only to the creation of new subdivided lots and development of those lots, but also to development, additions, reconstruction, or modification of structures on all other parcels of land, including without limitation previously-platted lots and parcels defined by metes and bounds descriptions, unless specifically exempted. The construction of new trails and the relocation of existing trails are subject to the standards in this Chapter 7.
