Vantage to Pomona Heights Chapter 3 230 kV Transmission Line Project FEIS Affected Environment PAGE 3-181 3.7.3.2 County Roads County roads are under the jurisdiction of each respective county’s road or public works department. Each County has a management plan, similar to a STIP, which provides planning guidance, necessity, and cost to programs such as road improvements, new road projects, and future transportation-related studies. Grant County utilizes a Transportation Improvement Program (TIP) known as the Grant County Comprehensive Six-Year TIP for 2015-2020 (Grant County 2014). Within the Project study area, there is one road receiving rehabilitation or improvements per the 2015-2020 TIP. The Beverly-Burke Road Overlay Project will consist of an asphalt overlay from SR-243 to SR-24. Kittitas County utilizes a TIP known as the Kittitas County Six-Year TIP for 2015-2020 (Kittitas County Department of Public Works ND). The County also publishes a document of ongoing projects every two years, currently known as the Kittitas County Roadway Improvement Projects of 2015-2020. Within the Project study area, there are no roads receiving rehabilitation or improvements per the 2015-2020 TIP. However, it should be noted that all roads receive a new layer of BST, which is a thin layer of liquid asphalt covered with an aggregate, every seven years. Yakima County utilizes a TIP known as the Yakima County Comprehensive Six-Year TIP for 2016-2021 for roadway system management (Yakima County 2015). Within the Project study area, there are no roads which will be receiving rehabilitation or improvements per the 2016-2021 TIP. However, it should be noted that all arterial roads receive a new layer of BST per determination through the Pavement Management System. Due to the number of gravel or dirt roads within the Project study area, blading is likely to be ongoing as part of the maintenance and erosion prevention of those roads. 3.7.3.3 Roads on BLM, Reclamation and JBLM YTC Administered Lands Roads on BLM and Reclamation-managed lands are often maintained and improved on an as-needed basis. Improvements or rehabilitation may require blading and grading to prevent further erosion and laying down additional gravel to make a more passable and safer traveling route. JBLM YTC maintains a system of roads for maintenance and operations of the facility and for fire breaks. JBLM YTC conducts annual maintenance of more than 200 miles of firebreaks to ensure fuel breaks are strategically located to compartmentalize fires, particularly in areas where fire hazards are high and along the installation boundary. Firebreaks also provide access to remote areas of the installation for suppression teams. In addition, enhancement of the installation’s road network has added more than 300 miles of roads that act as firebreaks (Army 2010). Traffic volume studies were done within JBLM YTC in 2007. According to these data, Firing Center Road has the highest volume of vehicles (2,533 vehicles) during an average weekday. All of the other roads experience relatively low traffic volumes. JBLM YTC’s Main Access Control Point (ACP; gate) is located on Firing Center Road just east of Pomona Heights Road. YTC’s Main ACP has one lane operating in each direction (one entering/one exiting). Because there is only one entering lane, queues and wait times are sometimes relatively long when entering the installation. It has been reported that this is primarily due to large military convoys or if there are several commercial trucks entering the post. The study showed that just east of Pomona Heights Road, there was an average of 135 vehicles entering and exiting the post during the 7 a.m. to 8 a.m. peak hour in June 2007. Thirty-nine vehicles were counted during the afternoon peak hour, which is shown to be from 3 p.m. to 4 p.m. During an average weekday, 810 vehicles in total were counted at this location (Army 2010).
