JUSTIN SUBSTATION MORROW-GROVER PRIMARY CIRCUIT On October 6, 2008, a meeting was held between the Crestview Neighborhood Association’s leadership and Austin Energy. The following questions were presented as follow up and we have attempted to answer them for the Association. WHAT IS THE SCOPE OF THE PROJECT? The project is an upgrade to an “existing” single phase service line that runs from Lamar, East on Morrow, crossing the railroad tracks and then turning south and proceeding on Grover Blvd. to Cullen Ave. The new electric line will be installed on new poles and the existing poles and electric lines will be removed. Telephone and cable lines will be re-attached to the new poles. WHY IS THE CIRCUIT NEEDED? AE’s planning department has identified the need to extend the Koenig Substation feeder to serve two purposes: 1) to provide adequate and reliable service to the Crestview Station project from Koenig Substation and 2) to continue to serve this new load and existing customers when the new substation near Crestview Station project, Justin Lane Substation, comes in to service and Koenig is taken out of service for reconstruction. AE is committed to provide reliable service. This circuit upgrade will help to ensure that reliability. IS THIS THE ONLY CIRCUIT COMING OUT OF THE NEW SUBSTATION? No, five circuits are planned to come out of the substation with the possibility of a sixth at some future date. There are two circuits that will go South along Lamar. One circuit will go across Lamar and go East on Morrow. Another circuit is planned to cross Morrow and go North on Watson. The remaining circuit is the Morrow-Grover circuit. All circuits will be constructed on existing pole lines. WHAT IS THE DIFFERNCE IN VOLTAGE BETWEEN THE EXISTING LINE AND THE NEW LINE? The existing service line is approximately 7,200 volts. The new line will be approximately 12,500 volts. WAS THERE A STUDY PERFORMED TO COMPARE THE COST OF UNDERGROUND VERSUS OVERHEAD? Our standard construction is overhead, that is what our rates are based on. A comprehensive analysis of overhead costs versus underground costs was not performed. In this case, there was an existing overhead line that has been in place for over 40 years is being rebuilt to handle the growing load and system changes. Generally the cost difference of overhead and underground for a project like this is 4 to 5 times, $100/ft. for overhead compared to $400-$500/ft. for underground. In addition to cost considerations the overhead installation is less intrusive to the existing neighborhood as AE will replace existing poles and pull new wire. Underground would require excavation of the front yards of all the homes along Grover and the installation of manholes (6’x12’x7’ concrete boxes) approximately every 200 feet. WAS CONSIDERATION GIVEN TO MOVE THE LINE ON GROVER CLOSER TO THE CURB? AE facilities are installed along public roadways in a specific “assignment”. Electric facilities are installed within the first three feet off the property line in the right of way. Other utilities such as gas and water are installed in the right of way beyond the 3 foot assignment. Given that, it is our understanding that there are other facilities in the right of way that would prohibit AE moving the lines closer to the curb. Since our meeting with the Association, we have requested confirmation of that information. WHAT TYPE OF POLES WILL BE INSTALLED? The new poles will be approximately 10 feet taller than the existing poles allowing for trees to grow higher before needing to be trimmed. This is part of AE’s ongoing effort to work with neighborhoods to minimize tree related issues. The majority of the poles will be wood. Where a turn in the line is required, metal poles will be installed to minimize the need for guy wires that support the poles. The metal poles will be directly embedded which means they will be installed in holes in the ground and not on a concrete pad. The metal poles will be “self weathering” poles which are the rust colored poles. WHO WILL BE DOING THE WORK? The majority of the poles along Morrow and Grover are owned by AT&T. Per our agreement with AT&T, AE or its contractor will perform the work. Should the AE contractor perform the work, there will be AE representatives providing oversight of the project. WHAT WILL BE DONE TO PROTECT MY YARD? AE or its contractor will attempt to minimize any impact on the yard areas. The poles along Morrow are located a significant distance from the curb due to the location of the right of way and most yards extend across that area. Therefore, our trucks will have to work in the yard. AE representatives will work with owners to restore the yard to as near the same condition as it was in prior to the work being done. HOW WILL TRAFFIC THROUGH THE NEIGHBORHOOD BE ADDRESSED? Projects of this type are required to have a traffic plan approved prior to construction. AE anticipates that the roadways will not be closed completely, but that a portion of a single lane may be closed with the appropriate signage or flaggers in place to provide traffic safety. Property owners will be able to access their property. You may be asked to move a vehicle to allow construction equipment to access the poles and minimize driving across the yard. WHAT TYPE OF COORDINATION WILL BE PROVIDED WITH THE NEIGHBORHOOD? AE will coordinate work in the area by notifying the Neighborhood Association as to when the project will begin. During the project, AE will have representatives to provide supervision and oversight of the project. During the project, if a customer has a question or issue, they are asked to call Sonny Poole – Supervisor – Public Involvement & Real Estate for Austin Energy at 322-6442 WHEN WILL THE WORK START? The project is currently scheduled to start the first of November. The project is expected to take 6-8 weeks for completion weather permitting.
