0000 muscog CASE STUDY 87-1 _ Poway, California Community Park Softball Fields Two lighted softball fields were included in the planning for Poway, California's new 28-acre Community Park project. The primary concern of Mr. Jim Bentz, acting director of Poway's Parks and Recreation Department, was spill light and glare control. It was considered of vital importance that spill light be minimized on a mobile home park located just .a 100 feet from the edge of the fields,and on an adjacent older resi- dential neighborhood. Not only did the city require that spill light and glare be reduced to an absolute minimum, but that a minimum footcandle level be maintained on the playing field area. } Based on these primary requirements,it was apparent to Jim I,. Bentz and the Poway city fathers that Musco's customized spill ,j- and glare control system was unmistakably the obvious choice to light the two new softball fields. It was just a few years prior that Musco was successful in significantly reducing annoying spill light emanating from the city's Lake Poway Championship soft- ball field. The field was initially located in a secluded area. However,the area surrounding the field soon thereafter began to develop into a residential neighborhood. CASE 87-1 SUMMARY "Musco was able to come in and retrofit our lighting system, even though it wasn't originally designed for glare control", Bentz said.
