DEVELOPING AN INTEGRATED MASTER PLAN “Gathering data was one of our very first tasks,” says Dietrich. “This involved digging deep into the Port’s information database. We explored numerous areas, including their existing regulatory requirements and future compliance issues. We also reviewed a large amount of GIS data as well as past construction plans. This supporting work ultimately resulted in five main work products that came together to form the Integrated Stormwater Master Plan.” Establishing the foundation for the Port’s future efforts, the five principal work products comprised: stormwater master plans; a stormwater design standards manual; stormwater asset management plans; stormwater models; and a regulatory compliance strategy and plans. “It’s easy to develop plans that just sit on a shelf and never get used,” says Arendt. “Our goal was to deliver useful work products to the client that could be implemented in their everyday operations at the different facilities. The products we developed address the Port’s regulatory needs, but they also allow the client to fully integrate stormwater management into their short- and long-term planning and operations as opposed to taking a project-by-project approach.”

One of the most ambitious stormwater master planning efforts ever attempted by an owner of airport and marine port facilities, the comprehensive project would cover more than 6,000 acres of Port of Portland property. It required extensive coordination between GS&P and the Port’s operations, maintenance, safety, environmental, development, engineering, finance, legal, and asset management departments to define their stormwater management issues and needs. The Port established individual project goals at the outset, which GS&P helped refine by shaping various stormwater management drivers into a focused plan for implementation that supported the client’s current operations as well as future development. “Having a strong relationship and open lines of communication with the client was key to the project’s success,” explains environmental engineer Tom Dietrich. “It not only helped us acquire critical information but also allowed us to vet the various processes and outputs so they were actually relevant and useful.” “Given the project’s scope and complexity, it was also critical to have the right team in place,” adds Arendt. “This was a massive undertaking that involved multiple needs and tasks. As lead, we recognized the value of utilizing the most qualified subconsultants on this type of project. So we brought a number of strategic partners on board, including Geosyntec Consultants and HDR, to help cover all of the major pieces.” To keep the multifaceted project on track, GS&P’s team utilized a matrix structure with a common set of tasks applied to each of the nine Port facilities. These included a thorough review of stormwater infrastructure data, stormwater characteristics and regulatory standards, the development of stormwater flow and quality models, and the preparation of asset management plans, stormwater design standards and stormwater master plans.
