This story was updated Feb. 17, 4:30 p.m. The city of Frisco and Brazos Electric have reached a stipulation agreement regarding the proposed power lines on Main Street in West Frisco. The agreement includes a hybrid overhead/underground route spanning nearly 3 miles along Main Street. The portion of the route that will be overhead span west of FM 423. The city has agreed to contribute more than $12 million toward the cost of the construction. The Public Utility Commission of Texas must approve the agreement before it can go into effect. The PUCT is scheduled to hear the agreement during its regular open meeting March 3. If the PUCT approves the agreement, the city and Brazos will coordinate on the design and construction of installing the power lines. The power lines installation will take place in conjunction with widening Main Street west of the Dallas North Tollway. The power lines installation is expected to be complete in a little more than two years, and the road construction is expected to last a little more than three years. If the city fails to meet its end of the agreement—provided that the conditions are within the city's control—the power lines route will be constructed overhead. The agreement has been signed by the city, Brazos, the PUCT staff and the Bury the Lines group, a Frisco group of homeowners and business owners that has advocated for buried power lines. Brazos submitted an application to the PUCT last year proposing to build power lines in West Frisco. The city, residents and business owners have been advocating to have the power lines buried since the application was submitted. The Frisco parties argue overhead power lines would inhibit the city from widening Main Street, lower property values and pose a danger to drivers. The estimated cost for burying the lines was estimated to be $28 million more than building overhead lines. This cost difference is why two administrative law judges recommended last November to build the lines overhead. Because Frisco has planned improvements to Main Street, which includes installing a water line and widening the road, the city has recommended coordinating construction to offset the cost of burying the lines. The hybrid route under the stipulation agreement is about $10 million less than the estimated cost of having the lines completely buried.
