Watermark was awarded a contract by the City of Lowell, in cooperation with the National Park Service, involving the development of the Western Canalway. Work involved the demolition of existing canal wall features, storm drainage system repairs, civil and structural modifications, and the installation of new site features. The project included new concrete retaining walls, a structural steel supported boardwalk, brick and paved walkways, lighting, and landscaping. Work also involved the fabrication and installation of a historically correct reproduction of a canal fence along the entire work area. Site lighting was also fabricated to be consistent with other reproduction lighting in other areas of the City from a similar period.
