Project Narrative

Eastern Harris County, particularly the area surrounding the Port of Houston, is experiencing increased development and population due to the region's vibrant economy. Increasing traffic as a result of this growth is causing a degradation of traffic operations on Harris County roadways. Harris County has identified Fairmont Parkway from Beltway 8 to 7th Street as a corridor that would benefit substantially from a combination of intersection geometric improvements, traffic signal modernization / rebuild / installations, fiber optic interconnect network, real time traffic monitoring and battery backup system. At approximately 50,000 vpd, portions of this roadway are among the most heaviest traveled roadway segments maintained by Harris County. The proposed intersection geometric improvements, traffic signal modernization / rebuild / installations, fiber optic interconnect network, real time traffic monitoring and battery backup system will enhance efforts to reduce motorist delay, congestion and improve air quality. Geometric improvements will provide additional intersection capacity and lane balance. Traffic signal improvements will optimize vehicle detection and utilize modern ITS equipment. Fiber optic interconnect network will allow remote monitoring and adjustment of signals operation and synchronization. Real time monitoring system will provide the public with average speed and travel time of vehicles along roadway sections. Also, collected data will be instrumental in the ability to develop ongoing transportation performance measures. Battery backup systems will be utilized to increase public safety and reduce traffic congestion by allowing traffic signals to operate during a power disruption / failure. Improvements are proposed at (14) intersection locations in Precinct 2, which intersects TxDOT-owned and maintained roadways. They consist of intersection geometric improvements, (4) traffic signal modernizations, (8) traffic signal rebuilds, (2) traffic signal installations with use of modern ITS equipment, upgraded vehicle detection, real time traffic monitoring, battery backup system and (8.5) miles of fiber optic interconnect network. At signalized intersections, traffic signal timing has previously been adjusted to optimize the efficiency with the existing geometry. No further enhancement alternatives are available.

Project Narrative

No

Categorical Exclusion (CE) (c)(26) Modernization of a highway which meets constraints in paragraph (e) Yes One utility crossing permit will be required, for installation of a fiber optic cable conduit crossing the Union Pacific Railroad’s tracks, west of SH 146. Experience has shown such minor permits can easily be completed during the time allotted to the design phase for a project of this type. Also, there is flexibility to install the conduit as either an underground crossing or as an overhead crossing because Fairmont Parkway crosses over the UPRR tracks at a bridge. This flexibility reduces the possibility of a permitting issue. 10/01/2015 No No Once utilities are identified as conflicts, each affected owner will be notified that their facilities will need to be relocated. Utility adjustments within County ROW are typically completed within 90 days with no cost to the County or the project budget. Yes The corridor is directly connected to facilities operated and maintained by Pasadena, La Porte, TxDOT, and HCTRA. Improving the county-maintained portion of the corridor will reduce overall delay. Discussions with TxDOT staff and others have been positive and in support of any improvement to their infrastructure. Completion of a fiber optic interconnect link between Beltway 8 and SH 146 also provides an opportunity to create redundant path in the multi-agency fiber network, improving network reliability.
