Visual Impact Assessment Griffith Energy Storage Project 7. The cultural modifications component of the visual quality rating criteria takes into account any humanmade modifications to the landform,water,vegetation,and/or the addition of humanmade structures. Depending on their character,these cultural modifications may detract from the scenery in the form of a negative intrusion,or they may complement and improve the scenic quality of a view. Based on the criteria above,views are rated numerically and a total score of visual quality can be tabulated.Table 1 summarizes the point associated with the various criteria. Based on this rating system,there are a total of 32 points possible.Views that score a total of 19 points or more are typically considered very high in visual quality(Class 1).Views that score a total of 12 to 19 points typically are considered to have a high to above average level of visual quality(Classes II and III). Finally,views that score a total of 11 points or less typically are considered to have average or lower visual quality(Class IV).Table 2 summarizes the point associated with the various criteria.Table 2 summarizes the point associated with the various criteria. Using the criteria below,the visual quality of the existing visual conditions and the post-Project ("simulated"condition)visual conditions will be rated.The scores will determine the Project site's existing visual class and evaluate whether the Project will result in a lower visual class and the degree of change between the existing and post-Project visual conditions.
