Results of the electromagnetic field (EMF) survey at San Luis Rey Elementary School indicated elevated EMF values within 150 feet of the powerlines compared to background levels, and a recommendation was made to locate new classrooms and play areas outside the 150-foot setback zone. However, the project would not exacerbate existing conditions as there are currently existing classrooms and play areas within the setback zone. A Field Management Plan was provided that describes additional measures that could be implemented during facility modernization to reduce overall EMF levels within the school to ensure EMF exposures would not be exacerbated compared to existing conditions.
