“Using EcoMetrix to calculate the benefits of environmental restoration is a game changer for freshwater ecosystems.”
Joe Whitworth, Executive Director, The Freshwater Trust
Parametrix is committed to providing sustainable solutions that improve environmental stewardship and social equity, while providing economic benefits. From low impact development and LEED solutions, measuring greenhouse gas emissions, to efficiently navigating changing regulatory requirements, we help our clients integrate sustainability measures. Examples of our sustainable solutions are illustrated throughout many pages on this site; here are just a few samples.
Until the early 1950s, Donkey Creek flowed freely from its headwaters to Austin Estuary and into Gig Harbor Bay. In the 1950s, much of the estuary was filled in and a 300-foot-long, 36-inch-wide culvert was installed to divert the creek beneath Harborview Drive. The goal of this project was to daylight Donkey Creek, restoring it and associated estuarine habitat to its near natural condition. The project evolved into a phased program of improvements to Austin Estuary and Donkey Creek with reconfigured roadways, a new 80-foot-long bridge over Donkey Creek, and a 14-foot-wide shared use trail linking Austin Park to Donkey Creek Park along the waterfront.
Pacific Avenue is the City of Bremerton’s primary downtown corridor. This project converts a five-block stretch of deteriorated corridor into a state-of-the art sustainable, green street and complete street that encourages revitalization and connects the City’s waterfront parks. The design by Parametrix was completed on a fast-track, 4-month schedule. The project involves creation of an urban trail, a full LID retrofit consisting of permeable pavement and rain gardens, as well as LED lighting and electric car charging stations.
Parametrix developed a sustainability strategy for the I-5 CRC that outlines 11 sustainability goals, including increased carbon sequestration, improved air and water quality, and reduced urban heat island effect. The strategy focuses on avoiding and minimizing impacts and achieving a sustainable, high-performing mix of travel options. The project team is committed to reducing the quantities of materials and energy required for construction and operation, reusing materials, recycling suitable materials from existing infrastructure, and minimizing the transport of materials by using locally-available reused and recycled construction materials. The team has analyzed anticipated climate change impacts and developed adaptation strategies to increase resilience and reduce long-term operation and maintenance costs. Daily greenhouse gas emissions from cars and trucks crossing the I-5 and I-205 bridges are anticipated to be reduced by approximately 9.5 percent.
Parametrix prepared a successful Department of Energy grant application and evaluated the feasibility of developing a commercial-scale solar energy system on the Reservation. The objectives were to develop an actionable roadmap for realizing energy security and independence, while reducing long-term energy costs and greenhouse gas emissions in a culturally-sensitive manner, and ultimately support the Tribe’s economic development goals. We developed energy baseline information and and inventory of greenhouse gas emissions from current facilities. We helped the Tribe develop a strategy to explore environmental markets, including developing renewable energy credits to offset system development and tribal energy costs.
Information presently available for siting coastal and marine renewable projects is often uncertain. Parametrix developed a spatial multi-criteria decision analysis system utilizing Bayesian decision methods and GIS-based data processing to inform the development of suitable areas for offshore energy projects. The system integrates oceanographic, ecological, human use data, stakeholder inputs, and cumulative impacts. It also accommodates an unlimited number of inputs, and integrates disparate data on bio-geophysical, social, and infrastructure information. The system is effective for identifying suitable areas for offshore ocean renewable energy projects and marine spatial planning in state territorial seas.
