City of El Segundo
El Segundo, California

El Segundo is a city in Los Angeles County, California, United States. Located on the Santa Monica Bay, it was incorporated on January 18, 1917, and is one of the Beach Cities of Los Angeles County and part of the South Bay Cities Council of Governments. The City of El Segundo established its Residential Sound Insulation (RSI) Program to offer owners of residential property most impacted by air traffic from Los Angeles International Airport (LAX) improvements to reduce noise within the home. These improvements, such as new windows, exterior doors, and attic insulation, are intended to help prevent exterior noise from interrupting such activities as sleep, conversations, and watching television. Participation in the Residential Sound Insulation Program is voluntary, and is offered at no cost to the property owner. Only residential property located within the 65 deciBel (dB-A) Community Noise Equivalent Level (CNEL) contour, and built before 1998 is eligible for the program.
