City of Sandy Transit Facility /Public Works Building, Sandy OR
Client: City of Sandy
Project Team: URS (Project Lead); Waterleaf Architecture, Interiors, & Planning (Project Architect); GreenWorks, PC (Project Landscape Architect); Interface Engineering (Building Plumbing Designer); Reyes Engineering, Inc. (Project Electrical Engineer); Firwood Design Group (Project Civil Engineer)
Firwood Design prepared the Civil plans for the 8 acre, City of Sandy Transit Facility and Public Works Buildings. Project design included site improvements for the administration/ operations building, maintenance buildings and the transit mall. Utility infrastructure, parking, lighting, and landscaping areas were designed to support the proposed new buildings and future building expansion areas. Unique to this design was the application of pervious asphalt in a section of the administration building parking area. Our stormwater design included treatment bio-swales. Firwood Design worked closely with the project team members including the construction contractor to achieve a successful design.
Third Street Sidewalk Improvements, Fairview, OR
Provided the engineering design for a new section of sidewalk within a residential block. The scope of this project included widening the road and in this section FDG incorporated pervious asphalt into the project to reduce stormwater runoff.
Unity Church Parking Lot Improvements– West Linn, OR
Completed a site improvement design to accommodate additional parking for a church. The project was unique in that the site exhibited relatively steep slopes and poor soil conditions. An aesthetically pleasing landscape design was of high importance along with addressing stormwater treatment from the new impervious surfaces. Both goals were achieved by incorporating a terraced three cell stormwater planter box system, planted with native vegetation, and designed with architectural stucco on exposed wall surfaces. The filtration planter box is a unique design in that the cells are tiered to incorporate into the topography and to allow for a waterfall effect. Once the first cell reaches a saturation level the overflow will waterfall into the lower second cell and once that cell becomes saturation the water will waterfall into the lower third cell.
Yu Commercial/ Retail Site Improvements – Vancouver, WA
Provided engineering design for site development improvements related to a 13,500 Commercial/Retail Building. Low Impact “Green” designs were utilized to treat and infiltrate the stormwater from the new impervious area of over an acre. Parking planter strips were integrated into the site design and served not only to treat the stormwater but added aesthetic appeal to the entire site. Project also entail securing utility and access easements from neighboring property.
A Rite-Way Roofing – Gresham, OR
Re-design for new parking improvements to incorporate a low-impact design to manage and treat stormwater runoff from the new impervious parking area. A specific assortment and placement of vegetation was utilized in planting the swale to achieve two goals. One to provide the stormwater treatment component and second to act as a screen for the neighboring property.
Mt. Hood Athletic Club Overflow Parking Lot- Sandy, OR
Prepared planning application and grading and construction plans for the expansion of the athletic club parking area to allow for overflow parking. The design incorporated a three celled vegetated filtration planter box to treat the stormwater runoff from the impervious parking lot area. Firwood provided construction inspection services and worked closely with the contractor to insure the planter box was properly constructed and planted.
