Anthem Duncan Developments LP | Sediment Remediation and Dike Construction

October 2, 2018

Project status

Permit amendment issued

In February 2021, amendment PER No. 16-179-01 was issued to Anthem Duncan Developments LP (Anthem) to conduct intertidal works outside of standard hours, and extend the permit validity. The amendment approved construction and physical activities to be conducted Monday to Sunday, from 8:00 p.m. to 7:00 a.m., excluding holidays, between February 10 and March 1, 2021. All other approved works will occur during standard hours. The amendment also extended the permit expiry date from February 28, 2021 to February 28, 2022. The project is located at 488 and 490 Furness Street (formerly 175 Duncan Street) in New Westminster, B.C. on lands and waters managed by the Vancouver Fraser Port Authority.

The project permit for the Sediment Remediation and Dike Construction project was issued on July 11, 2019. The project was approved subject to 49 permit conditions which Anthem must meet to ensure the project does not result in significant adverse environmental effects.

About the amendment

Advisian on behalf of Anthem Duncan Developments LP proposed to carry out physical works related to the approved Project Permit No. 16-179: Sediment Remediation and Dike Construction beyond the standard construction hours (Condition 24 of the permit), and also requested to extend the permit expiry date from February 28, 2021 to February 28, 2022.

Low tide in February may occur late or early in the day and outside of the standard work hours of 7:00 a.m. to 8:00 p.m. The extended work hours amendment was requested 24 hours a day, seven days a week, to allow for intertidal construction to be completed before, during and after low tide in February 2021. All other approved works will occur during standard hours. Intertidal works are proposed to occur during low tide to minimize erosion and sedimentation and to increase the effectiveness of construction works. Temporary lighting required for night works will be directed down and away from residential lines of site as much as possible. Potential noise will include movement from an excavator and front-end loader and a generator.

The permit expiry extension was requested because additional time is required to complete the project. The permit was approved July 11, 2019 with an expiry of February 28, 2021. The shoreline remediation and protection design has evolved and is taking longer to complete than anticipated. The proponent has requested a new permit expiry of February 28, 2022 to complete the project within the permitted timeframe.

About the project

Anthem Duncan Developments LP proposes to construct a townhouse development and dike at 41 and 175 Duncan Street, which was previously an industrial facility. The townhouse development and associated dike construction are outside the port authority’s jurisdiction. The associated scope of works proposed in the port authority’s jurisdiction include foreshore structure demolishing and removal, remediation, vegetation removal, and some minor construction activities to support dike construction. Up to eight trees are proposed to be removed.

Project activities and components include:

  • Intertidal works, including:
    • Removal of the existing temporary shoreline protection which includes sandbags and lock blocks
    • Remedial excavation
    • Installation of filter rock and rip rap rock
    • Temporary lighting with a generator
  • Removal of concrete retaining wall, miscellaneous debris, and soil with a land-based excavator
  • Placement of soil and debris into interim containers and trucks for daily removal from site to approved disposal facility
  • Remediation of 1,252 m3 of contaminated sediment below the high-water mark using land or marine-based excavators, depending on accessibility
    • Marine-based excavators will be mounted on a spudded barge
  • Upland disposal of contaminated sediment by truck or by barge
  • Minor and temporary excavation, stock piling, and backfilling activities to support dike construction on the western edge
    • All other dike construction activities are outside the port authority’s jurisdiction
  • Removal of up to eight trees

Construction started in August 2019. All works are planned to be completed within the Fisheries and Oceans Canada’s recommended least-risk work window for the area (June 16 to February 28).
