Inquiry

Our project is a new 10,000 s.f. clinic building on a piece of property that is owned by the building owner/occupant. The owner/occupant originally purchased a 2.1 acre site that has been subdivided into two parcels, one a 1.1 acre site for this project and another 1 acre site that will be developed in the future. The overall site of 2.1 acres has been master planned to share site access, has shared parking easements and shared site lighting. The development has been approved as such by the city. Not knowing when the second parcel of land will be developed, we would like to design the site lighting to provide adequate lighting for safety and comfort at the site access (which the property line between the two parcels splits evenly) and provide for the most energy efficient lighting for both parcels. My concern for this credit is at the property line that separates these two shared parking areas and their site lighting. The shared site lighting design, which provides the most efficient lighting for both parcels, creates a light trespass problem at the property line that separates the two. By trying to meet the requirements for this credit and meet the light level requirements at the property lines, I don\'t provide adequate lighting for safety at our shared access to the site and by shifting light poles in board to the site I don\'t provide for the most energy efficient site lighting design and I don\'t provide adequate lighting in the parking lot area, next to the property line, for safety and comfort. All other property line required light levels will be met. Is it acceptable to design the site lighting to exceed the required lighting levels at this shared property line situation and be awarded the credit for Sustainable Sites Credit 8, Light Pollution Reduction?
