SHELDON-WATERMAN ROAD ROUNDABOUT
ELK GROVE, CA
In rural Elk Grove, residents and local commuters frequently faced delays due to the four-way stop controlled intersection, especially during peak commuting hours. To improve traffic flow and safety for motorists, pedestrians and cyclists, the four-way stop was converted to a roundabout. The new intersection at Sheldon and Waterman Roads includes pervious colored concrete pedestrian paths, artwork and historic farm equipment themed to match the rural character of the area, and accommodations for shoulders/bike lanes as well as connectivity with a future multi-use pathway. This project won the 2017 Public Works Project of the Year Award in Transportation from the APWA Sacramento Chapter.
U.S. 20 CASCADE HIGHWAY IMPROVEMENTS
Quincy completed the roadway design on this $2.3 million project to replace the sidewalks in downtown Sisters with pavers to provide aesthetic treatments. The project also replaced the existing highway asphalt pavement to better handle truck loads along with minor adjustments to the profile to improve drainage. Downtown closures were allowed three blocks at a time and traffic was detoured onto the adjacent local streets. A major detour around the downtown area was constructed first, including new traffic signals, to keep inter-regional truck traffic out of the construction zone altogether. This project received the American Public Works Association (APWA) 2015 Project of the Year Award.
SAN PABLO DAM ROAD
CONTRA COSTA COUNTY, CA
Quincy provided project management and complete engineering services for the San Pablo Dam Road Walkability and Community Enhancement Project, a ½-mile safety improvement project on San Pablo Dam Road from El Portal Drive in El Sobrante to Apian Way in Pinole. Quincy aided Contra Costa County with meeting its goal to rejuvenate the area by upgrading infrastructure, replacing cracked pavement and enhancing the community with “greening” efforts. Quincy redesigned the existing sidewalks to meet ADA compliance, relocated existing AC Transit bus stops, improved drainage and vegetation, coordinated utility relocation, provided right-of-way appraisals and acquisitions, conducted extensive public outreach efforts and provided construction support.
LANCE GULCH ROAD
Lance Gulch Road (formerly referred to as the East Connector) is a new alignment (1.4 miles long) that was constructed in 2014 along the east side of Weaverville through partially developed land in Trinity County. The new roadway included two new public road connections and provided access to Trinity River Lumber Company. Roadway improvements included design for large trucks, pedestrians, and bicycle use. The project design features include extensive drainage in compliance with water quality permits, and creation of a new on-site wetland and riparian mitigation areas.
CHALLENGES & SOLUTIONS
The path to designing a new road or replacing one isn't always a straight shot. Here are some of the biggest challenges we've seen over the years and ways we've helped clients solve them.
Engaging the community during the design process can help eliminate some of the bigger issues that often creep up down the road. By working with local residents and business owners early on, we can produce better designs that more effectively meet stakeholder needs.
Projects can easily be delayed because of right-of-way issues, a highly sensitive topic for local homeowners and businesses. That's why we work to identify right-of-way needs up front before the project is well underway.
Dealing with various utilities, from overhead telephone wires to underground gas pipelines, is something our team works on regularly. We ensure early utility coordination so any relocation can occur efficiently without affecting the project's timeline.
