FAA Responds to Proposed Changes to Torrance Airport Helicopter Routes
The Torrance City Council adopted improved helicopter routes and altitude flight levels at its February 1, 2011 meeting. A Helicopter Committee consisting of Torrance residents, aviation experts and government officials was formed to study the issue of helicopter noise generated along established routes flying into and out of Torrance Airport. After extensive research, the Helicopter Committee recommended route modifications and increased flying altitudes from 600 feet msl to at least 1,200 feet msl along 3 primary routes from the Airport. Its recommendation was forwarded to the Torrance Airport Commission which accepted the route modifications, but rejected the flight altitude increase, claiming it posed a safety risk by placing helicopters and light aircraft in too close proximity. Torrance City staff disagreed with the Airport Commission’s conclusions and recommended that the City Council endorse the Helicopter Committee’s recommendations.
Changes to South Crenshaw Helicopter Route Over the Palos Verdes Peninsula
This decision will reduce the impact on Peninsula residents by modifying the existing South Crenshaw Helicopter route and increasing the minimum height to 2,000 feet mean sea level (msl) along the high elevation points along the route. While only ten percent of Torrance Airport helicopter traffic follows this route, Rancho Palos Verdes staff believed it was important to eliminate or minimize the noise impact on residents. When attempts to eliminate the route proved unsuccessful, staff then worked to minimize residential impact by modifying the route so it flew over the Portuguese Bend Nature Preserve rather than fly near Terranea Resort, Abalone Cove Shoreline Park and adjacent neighborhoods. The route previously ended near the intersection of Crenshaw Boulevard and Indian Peak.
The adopted South Crenshaw route modification is expected to reduce over-flights over more densely-populated Rancho Palos Verdes neighborhoods. Higher altitude levels will also reduce the noise impact on City residents.
Torrance Airport Management contacted the Federal Aviation Administration (FAA) in a February 24, 2011 letter about these proposed changes and requested that the FAA review and approve modifications to the “Helicopter Letter of Agreement” (LOA). The letter outlined the proposed changes, reviewed the process that the City of Torrance went through, and explained that the changes would be implemented over a six-month trial period to monitor how effective the changes were in providing noise mitigation without impacting safety. The stated intent was to work with the FAA to implement permanent modification to the LOA after the six-month trial period.
The Operations Support Group Manager for the FAA responded to Torrance Airport’s letter on April 15, 2011. The FAA’s letter identified a number of steps beyond Torrance’s basic requested review and approval, which would need to be completed before a test procedure could be implemented. The letter noted the need for an aeronautical analysis of helicopter and fixed wing traffic, which would be performed by the FAA and would take approximately four months. Additionally, the letter called for a noise analysis or Integrated Noise Modeling for the South Crenshaw route to be undertaken and paid for by the City of Torrance. The FAA noted that the portion of the South Crenshaw route extension running from approximately Indian Peak to the Pacific Ocean is outside of Class D airspace which is the typical boundary limit for charting helicopter routes. This proposed extension would also call for a new noise profile analysis. Finally, the FAA requested more information about how Torrance Airport and the Torrance City Council intend to evaluate the testing of the new routes.

The issue was discussed at Torrance Airport Helicopter Committee meetings on April 21 and May 5, 2011. City of Rancho Palos Verdes staff attended both meetings. Committee Chairman Pete Elmore advised the Committee that Torrance Airport should conduct noise modeling for the Pacific Coast Highway east route (heading to the harbor area) and the South Crenshaw route. Torrance Airport staff has not officially responded to the FAA as of May 12, 2011.
While the great majority of Torrance Airport helicopter activity does not encroach upon Peninsula airspace, staff believes it is important to monitor this development and other airspace issue to minimize any potential negative impacts on our residents.
