Context The bank is located in a heavily developed commercial area on Route 29 North. The ATM is located at the north end of the site and building, at the outer (northern) lane of the drive - through structure, approximately 100' from the EC right -of -way. Visibility The ATM is visible from the Entrance Corridor. The bank building and the wooded slope on the north side of the parcel help limit visibility, but the addition of illumination at and around the ATM will increase noticeability at night.

DETAILS OF THE PROPOSAL • The bank's internal security requirements call for 2 fc of illumination at locations 50' from the ATM (or at the retaining wall) and 10 fc at locations 5' from the ATM. • The applicant has presented two designs for upgrading the lighting to meet these requirements. Both designs include two poles, with two fixtures mounted on each pole. • In the first proposal, the pole- mounted fixtures are mounted on the roof of the drive -thru structure. In the second proposal, the pole - mounted fixtures are located at the ends of the ATM island. • Both designs also include fixtures mounted within the canopy that is mounted over the ATM.

Staff recognizes that the applicant has tried to find workable alternatives. The current proposals meet the bank's requirements and, with a few adjustments, could meet the requirements of the lighting ordinance. However, although the need for security is clear, the illumination levels do not meet the EC guidelines and there are no guidelines regarding security. Complete fc readings were not provided. Continuing the fc readings across the parking lot would result in a more complete illustration of the impacts of the proposed lighting. 26 Dark brown, dark bronze, or black are The color of the poles and the pole - mounted Include a note in the luminaire appropriate colors for free - standing pole fixtures is not identified on the plans.

The plans show a house side shield (HSS) on the ground- mounted pole fixtures to prevent light spill onto the drive -thru roof. The plans do not show shields on the roof - mounted fixtures, although the applicant's memo indicates that shields are proposed for them. Neither photometric plan shows fc readings on the drive - through roof. If the roof mounted pole lights are approved, the drawings should be revised to include the shields. 28 In determining the appropriateness of The site is visible for approximately 600' See recommendations above lighting fixtures for the Entrance along the EC.

Because the ATM is set back from the face of the main building, it is not visible until the viewer has reached the north side of the main building. Traveling southbound, the site becomes visible just beyond the wooded slope and visibility of the ATM is lost just beyond the main building. Even though the applicant is not attempting to provide general site lighting, the proposed light fixtures will illuminate the area between the ATM and the retaining wall, the wooded sloped (though actual fc levels may be lower than some of those shown in this area), the area around the northern exit from the site onto Rt. 29, and the north end of the parking row that runs along the EC. It is anticipated that all of this illumination will be noticed at night even if the ATM itself is not. 29 The following note should be included on The note does not appear on the plan.
