The results of our field explorations and laboratory testing programs have provided the basis for our engineering analyses and design recommendations. The following discussions of our findings and recommendations are subject to the Limitations attached as Appendix IV to this report. Site Conditions Surface Features: The subject site is the existing fenced-in West Orange Switching Station. The station is bound by Mt. Pleasant Avenue (State Route 10) to the south and Prospect Avenue to the east. A medical office complex is located to the west, and an LA Fitness and additional medical office building is located to the north of the station. Marion substation is located at the northwest corner of the station. The station contains various electrical equipment, control houses and other improvements typical of PSE&G stations, however the proposed improvement area would be located at the southeast corner of the site, within unimproved lawn and wooded areas. Topographic information provided to us indicates that the site generally slopes steeply downward from Mt. Pleasant Avenue and Prospect Avenue into the site where grades generally level off and gradually slope downward towards the existing station equipment which is established near Elevation +599 feet to +603 feet. Subsurface Conditions: The subsurface conditions encountered in the explorations performed for this study consisted of the following generalized strata, listed in order of increasing depth: An Equal Opportunity Employer M/F/V/H
