This project represents a tremendous opportunity to explore and identify low-carbon solutions as the demand for cement, concrete and other critical materials is poised to grow, driven by rising population and the need for resilient buildings and infrastructure. By studying stakeholder-specific processes and practices for cement and concrete - materials integral to modern societies - we identify the obstacles for adopting decarbonization pathways. This project serves as the initial framework for how the greater Maryland’s architectural, engineering and construction (AEC) community and the governmental agencies can reduce project greenhouse gas emissions, establish net-zero emission goals, and ensure climate justice.
Mobility infrastructure - GreenPlum Street developed a highly graphical inventory of City of Seattle school zones, recommended safety improvements, and cost estimates for all Seattle public schools from kindergarten through high school. In addition, we worked closely with City staff to develop project documentation for priority projects based on equity scoring.
Government sustainable agendas - As part of the City of Bothell Comprehensive Plan Update process, GreenPlum Street served as the policy expert for the development of the Transportation Element (TE) update. GreenPlum Street skillfully led City staff through the process of modernizing the City’s transportation goals, policies, and implementation actions to support the fulfillment of its 20-year multi-modal transportation vision.
Program management - Every Type III Environmental Product Declaration (EPD) needs to be verified by an independent third party before it can be published. GreenPlum Street ensures the accuracy and reliability of the LCA and EPD, and that it conforms to the requirements of the relevant Product Category Rules (PCR).
Mobility Infrastructure - GreenPlum Street helped examine where there are opportunities to increase connectivity for people walking, biking, and driving in the City of Shoreline, recommended policy and code updates to support implementation of the new connections, and identified different mechanisms to fund these connections.
While serving as the City of Shoreline's Senior Transportation Planner, Nora spearheaded the City’s adoption of a Complete Streets Ordinance that requires all roadway projects to be designed to accommodate all travel modes, including walking, biking, driving, and riding transit. The policy provides the legal teeth to shift from an auto-dependent community to one that offers multiple ways of getting around.
Subsequently, Nora led three rounds of successful grant applications for the Washington Transportation Improvement Board’s Complete Streets Award, collectively funding more than 1.5 million dollars of pedestrian and bicycle improvements in Shoreline.
As the City's Senior Transportation Planner, Nora led the vision for a trail that will run parallel to the light rail extension. The Trail Along the Rail will provide direct pedestrian and bike access to the 148th and 185th St. Stations, and beyond to the existing 195th St. pedestrian bridge. In addition, the trail will connect to parks, schools, business districts, and more. The trail also fits into a bigger vision of growing the regional trail network that will ultimately connect light rail communities throughout Puget Sound.
For the opening of the light rail extension on August 30, 2024, about 20 non-contiguous blocks of trail were constructed in partnership with Sound Transit. Now, the City is pursuing grant funding to build the full vision of the trail.
During a very transformative time when the City of Shoreline was getting ready to open two new light rail stations, this timely study of how shared-use mobility hubs provide space for first and last mile connections to bikeshare, scootershare, carshare, as well as ride-hailing services.

Trade Association of the Year by Reed Awards with 75+ legislative victories
Each year, fire kills more Americans than all other natural disasters combined. It has become clear that current code language puts citizens, fire fighters, and other first responders at risk. To address climate changes, increase population and expanded use of combustible materials, Tien engaged in data analytics, represented the construction industry and proposed several code changes and legislative bills to ensure public safety through the functional recovery of property and community.

Nora led the strategic vision to strengthen the vitality of Skyway Park by activating its edges and reinvigorating its interior through a broad palette of design interventions. Through a community-based outreach process, a set of park activation projects were identified to draw multigenerational use and spontaneous play.
Activation projects included a gateway park and a street vacation to create a more inviting and playful entrance to the park as well as major upgrades to the park’s sports fields, paths, parking, and lighting.
In 2023, King County Parks implemented $2.92 million of capital improvements based on the activation plan.
