Civil Engineering for Bellingham townhome project
Alpine Engineering provided civil engineering in support of a new six-unit townhome project on Old Fairhaven Parkway in Bellingham, WA. The civil engineering design incorporated low impact development (LID) stormwater elements such as pervious concrete and bioretention for onsite stormwater treatment. The site had space challenges and required an underground, reinforced concrete vault design to attenuate stormwater volume runoff to meet Washington Department of Ecology and City of Bellingham minimum requirements for stormwater volume control.
The project also was required to provide right of way improvements, including pervious concrete public parking, stormwater management, a sidewalk, new paving and landscaping. Our work involved permitting support and consultation with the City of Bellingham’s Public Works Department and Building Department.
Architect: Allen Design
July 14, 2020 update: Excavation and site preparation are well underway. The placement of drainage features and a site wall have started, and crews are working to set foundation forms. The building should start taking shape soon!
August 3, 2020: The two underground stormwater vaults are cast in place! The stormwater vaults will provide flow control per WA Department of Ecology and The City of Bellingham stormwater requirements. Reinforced concrete tops will be installed next and eventually vehicles will park on top of the stormwater vaults.
September 2021: The project is finished and residence have moved in!
