City of Tustin Caves to Legal Pressure and Allows Cell Tower Application
See post below for details



T-Mobile and the City of Tustin planned to erect a 65 foot cell phone tower at the back end of the park near the gate to Peters Canyon Elementary school. The proposal received approval from the Tustin Zoning Commission despite vigorous opposition at the public meeting on Wednesday, October 20th. Due in large part to additional opposition raised by local residents in the days following this meeting, and at the request of Tustin City Council Member Doug Davert, the Zoning Commission decision was vacated on October 27th, and a public hearing before the Planning Commission was set for December 14, 2010, to allow for additional public input.

T-Mobile has redesigned the proposed installation to look like 3, 45' tall flag poles located in the parking area of the park. While this is a better design, it will only accommodate their equipment and, if another carrier wants to place an installation in the park additional towers must be built.

Our Position

We are not opposed to the use of cell phones and wireless technology, and acknowledge that cell phone coverage in the Peters Canyon area of Tustin Ranch is sub-standard. However, we feel that Cedar Grove Park is no place for a cell tower due to its historic significance, scenic beauty, and close proximity to Peters Canyon Elementary and Pioneer Middle Schools. We also feel that a tower at this location will have a negative impact on property values of homes nearby. Once it is done, it cannot be undone.

Desired Goal

Our goal is to convince the Planning Commission, Tustin City Council, and T-Mobile to consider alternate sites for a cell tower to serve the needs of the Peters Canyon area that will have less negative impact on the neighboring communities.

Many cities around Southern California are in battles with their city officials and T-Mobile, or other cell service providers, due to the proliferation of cell towers in residential neighborhoods. Often the first notice residents have of a tower going up is when the construction crews arrive to start breaking ground. We advocate greater transparency in the selection process of these sites and inclusion of the local residents in the final approval to assure that the best possible site is selected and the negative impacts to the community are minimized.

An alternate location for a cell installation exists just 400 yards from Cedar Grove Park at the Orange County Fire Authority complex on Jamboree Road. Two cell towers have been approved for construction there and Verizon, AT&T, and Sprint have already agreed to place their equipment at this facility. We feel T-Mobile should do the same.

How does 911 Service on cell phones work?

Even if your cell carrier is unable to pick up your 911 call, federal law requires that your 911 call be transmitted by other wireless carrier(s) covering the area, regardless of who your wireless contract (or lack thereof) is with. These calls are picked up by any carrier with similar technology (AT&T and T-Mobile use GSM technology while Sprint, Verizon, Metro PCS, and U.S. Cellular use CDMA technology) and directed to what is called a Public Safety Answering Point (PSAP), which is a call center responsible for transferring calls to police, fire, or ambulance services. There are approximately 6,100 primary and secondary PSAP’s nationwide.

Enhanced 911 services in the cellular industry have been implemented in two phases. Phase I Enhanced 911 (E911) requires wireless service providers to provide the PSAP with the telephone number of the originator of a wireless 911 call and the location of the cell site or base station transmitting the call within six minutes of a valid request. Phase II E911 requires the provider to give the latitude and longitude of the caller to the PSAP with in six minutes of a valid request by a PSAP. This information must be accurate to within 50 to 300 meters depending on the type of technology used.

The FCC required wireless carriers to have Phase II E911 for 95% of their subscribers by the end of 2005, however, because of the complexity of the coordination and technology required from wireless carriers, it is still important to stay on the line and provide the dispatcher with as much information about the exact location of the emergency to ensure help can be dispatched to the correct location.
