25TH STREET BIKE AND PEDESTRIAN IMPROVEMENTS PROJECT - Bellingham, WA (2014)

Reference: City of Bellingham Public Works, Ted Carlson

This project evaluated the many intricate and specialized issues identified along 25th Street and Douglas Avenue in south Bellingham. Improvements to roadway, low-impact design, ADA accessibility, landscaping, and stormwater features collectively improved pedestrian access and safety, delineated vehicular from pedestrian routes of travel, increased overall corridor capacity and circulation, improved and enhanced existing stormwater quality controls, and provided minimalistic impacts to the environment. This project showcases our ability to effectively design, manage, and provide construction engineering of an urban infrastructure project.

In May 2015, this project was awarded the Local Outstanding Civil Engineering Achievement Award by the American Society of Civil Engineers (Seattle Section) for its innovative design, aesthetics, environmental sustainability, cost efficiencies, and the effective reuse and recycling of construction materials.

In 2016, it received a Silver Certification from Greenroads. The Greenroads Rating System is an effective way to measure and manage sustainability on transportation projects. The Rating System challenges design teams to produce designs above and beyond minimal environmental, social, and economic practices.

I-5 SAMISH TO SUNSET CORRIDOR IMPROVEMENTS PROJECTS - Bellingham, WA (2000-2007)

Reference: Washington State Department of Transportation, Gus Deeter

This project started with scoping the development of 14 interchange improvement projects along Interstate 5 through the City of Bellingham. Initial duties included programmatic scoping, identification of infrastructure deficiencies, inventories of site features and critical areas, and preliminary engineering. Subsequently, a strengths and weaknesses process was conducted to identify a strategic and methodical use of limited federal funding allocated to the project. The results of this process prioritized projects totaling over $36 million. This project showcased our ability to successfully navigate the detailed planning, feasibility, and design processes associated to large-scale highway projects.

SR 542 CHURCH MOUNTAIN ROADWAY REALIGNMENT PROJECT - Whatcom County, WA (2007)

Reference: Washington State Department of Transportation, Gus Deeter

This project solved a perpetual environmental threat to a rural section of Mount Baker Highway and eliminated the need for yearly permit approvals from resource agencies. Initially, a feasibility assessment of the site was performed to identify the best solution with the least impact. It was ultimately determined to realign 0.5 miles of highway, replace a fish passage culvert with a bridge, and install earth retaining walls and soft bank stabilization. Improvement to deficient roadway alignments, limited sight distances, and yearly flooding problems were also realized. This project showcased our ability to design, permit, and construct a project under challenging site conditions and confined work environments.

ROEDER AVENUE - BELLWETHER WAY SIGNALIZATION PROJECT - Bellingham, WA (2009)

Roeder Avenue - Bellweather Way Signalization

In this combined services project, preliminary traffic planning was conducted and fulfilled with completion of final design of proposed intersection improvements. John Tuttle assisted an engineering consultant with evaluation of two intersection management options, a single-lane roundabout versus a conventional signal controlled intersection. A side-by-side analysis of traffic operation, construction cost, safety, right-ofway, and environmental impacts was conducted to best qualify the most effective management option. Follow up traffic assessment services were provided with independent review and QA/QC assurance on permitting, plans, specifications, and cost estimate documentation.

PETERSON ROAD WIDENING AND UTILITY IMPROVEMENTS - Burlington, WA (2000)

Reference: City of Burlington , Marv Pulst

This project widened an existing two-lane roadway and updated its existing stormwater conveyance system to accommodate increased traffic and runoff expected by the expansion of the current city limit boundary. In collaboration with a team of designers, John Tuttle performed geometric roadway design, land-use permitting, stormwater collection, conveyance, and pumping design, and in the creation of a bid-ready set of plans and provisions for this federally-funded project. The completed project improved east‐west traffic flow, reduced traffic delays at adjacent intersections, and helped develop a more defined roadway pattern identified by the City in its long-range transportation plan. This project showcases our ability to effectively perform detailed site assessments, phased planning, and multi-disciplinary design and permitting. Project Budget: $1.1M.

25TH STREET - BILL MCDONALD PARKWAY SIGNALIZATION PROJECT - Bellingham, WA (2010)

Reference: City of Bellingham Public Works, Rory Routhe

This project included the design and management of intersection improvements funded by a partnership between the City of Bellingham and Western Washington University. Improvements were made to an intersection lacking sufficient pedestrian channelization measures. A four-way signal was chosen for its ability to enhance pedestrian safety and to reduce speeds along this section of roadway. The intersection was also expanded to improve large truck access and re-channelized to separate vehicular movements from pedestrian movements. The project had an aggressive design and construction timeline, and was completed on-time and under budget. This project showcases our ability to successfully design, permit, and construct a project with challenging site conditions. Project Budget: $340,000.
