After two decades, Herrera is excited to see the Tacoma/Pierce County HOV Program near completion. The Program, developed by the Washington State Department of Transportation (WSDOT), consists of over 14 projects built from 2001 to 2022 totaling $1.4 Billion dollars. Since its inception, over 25 HOV lane miles have been added to I-5, SR 16 and SR 167.
In addition to new HOV lanes, this program aims to improve safety by enhancing lanes and lighting, better roadway alignments to improve mobility, improve electronic communication with travelers, and promote a healthier environment by minimizing traffic noise, expanding nearby wetlands and improving stormwater treatment methods.
Beginning in 2006, Herrera has assisted in the planning, design, and permitting of several projects within the Tacoma/Pierce County HOV Program. To help Pierce County meet environmental goals, Herrera supported the preparation of a NEPA Environmental Impact Statement, developed mitigation plans for wetland impacts, and evaluated alternative stormwater treatment approaches to adequately protect water quality in the Puyallup River, Hylebos Creek, and other streams in the program corridor.
Additionally, Herrera designed enhancements to aquatic habitat while fulfilling project requirements for flow control of I-5 stormwater runoff by conducting baseline monitoring and leading the design of a unique floodplain restoration site near the confluence of Hylebos Creek and Surprise Lake Tributary.
Herrera is excited to continue to partner with WSDOT to support sustainable solutions while improving our local infrastructure. More information on this project can be found here.
