                       SCENIC QUALITY CLASSES AND DESCRIPTIONS

INTRODUCTION

The BLM and Forest Service, as land-managing agencies concerned with visual characteristics of
landscape, have developed methodologies to assess the scenic quality of landscapes to help determine a
project’s effects on the surrounding environment. These methodologies were used for Federal land and
were borrowed for use in assessing landscapes outside areas where formal guidelines apply. The BLM’s
Visual Resource Management approach assigns classes to landscapes indicating aesthetic value based on
defined characteristics. Classes derived from the BLM and Forest Service approaches were used to
develop a consistent description of the scenic quality of the natural landscapes within the study area and a
class was created for developed land. The description is a composite of separate components of visual
resources and is further explained in Table I-1. Scenic quality classes assigned to the landscapes of each
project component and a description of the character specific to each landscape follow in Tables I-2
through I-7 below. Also, these scenic quality classes are shown in Map 3-16. Landscape characteristics
are described in Chapter 3, Section 3.14.

       Class
      Class A          Unique land of outstanding or distinctive diversity or interest, such as high relief
                       mountains, escarpments, highly dissected canyons, monumental landforms, and
                       scenic riverways.
      Class B          Land of common or average diversity of interest, consisting of rolling vegetated
                       hills and valleys, mesas, and buttes.
      Class C          Highly common land and/or land of minimal diversity or interest, such as high
                       desert plateaus or desert basin areas.
      Class D          Landscapes that have a modified appearance and that exhibit human-made
                       modifications as a result of development, including residential, commercial, and
                       industrial land uses.

                          Leupp, the area of Tolani Lake, and the Black Mesa Complex have the
                          characteristic low topographic relief, including dissected plains, sandstone
                          plains, and high desert plateaus.

                          uncommon features such as eroded precipices, colorful contrasting rock
                          striations, and narrow chasms within the canyons. The landforms also exhibit
                          vivid warm and cool contrasting colors as well as the distinguishing textures of
                          rock outcrops and exposed sandstone strata.
                          Class B. The natural landscapes along the western route include the Little

                          Valley, and many distinctive mesas (Tohnali, Newberry, Coal Mine, and Black
                          Mesa). Plateau grassland, various mesas, and other unique landscapes mostly
                          characterize this area; however, they are not uncommon features in the area.
                          Class D. The western route begins north of the community of Leupp and the

                          terrain, with little spacial definition, vast expanses of sagebrush or plains
                          grassland vegetation, and developed industrial areas.
