John H. Oxian, President South Bend and St. Joseph County HISTORIC PRESERVATION COMMISSION 227 WEST JEFFERSON BLVD. SOUTH BEND, IN 46601-1830 Mr. Michael Kummeth DLZ 2211 East Jefferson Blvd. South Bend, IN 46601 Phone: 574-235-9798 Fax: 574-235-9578 e-mail: historic@michiana.org A Certified Local Government March 9, 2004 RE: LaSalle Street Bridge Lighting Dear Mike: `OMMISSIONE.q SCw. OJT �•� O N a v t = 0o coo Karen R. Hammond -Nash, Director Thank you for your attendance, and for the data you presented at the Historic Preservation Com- mission committee meeting Monday. Pursuant to that meeting, I am writing to confirm that the Historic Preservation Commission is convinced that the "QL" quick induction lights proposed for the LaSalle Street Bridge would, on the basis of the data you showed us, clearly provide color rendering and color temperature as good or better than the metal halide previously specified. Just as a side note, we did notice that all the engineering data presented came from Philips Co. Presumably, there are other lighting companies, including American companies, which also produce com- parable products. As long as the products are comparable, HPC would not want to limit specifications to one manufacturer. One concern HPC members had that was not totally answered is whether such lights are available in appropriate (i.e., not excessive) lumens for the height of the fixtures to be used. Many modern lights are designed to be used atop two or three story -tall cobra -headed poles, and are therefore excessively bright and glaring when used in historic or reproduction poles, which tend to be shorter. Philips did have some data regarding lights they supplied in Bruges, Belgium, which was described as lower lumens to accommodate historic Belle Epoque fixtures, but HPC staff found limited description of that in English. Assuming that you can find us an auspicious answer regarding that matter, the Historic Preserva- tion Commission anticipates approving the use of the proposed quick induction lighting for the LaSalle Street bridge, and also probably, assuming that the South Bend Public Works Department and the various neighborhood associations involved so desires, revising our standards regarding historic district and land- mark lighting generally to allow quick induction lighting there as well.
