2016 Peace Region Flood Response

CLIENT: Ministry of Transportation and Infrastructure

YEARS: 2016-2017

In mid June 2016, a storm with heavy rainfall caused flooding in the Peace Region, resulting in washouts and damage to multiple crossings along Highways 29, 52, and 97, as well as several main and side roads in the region. Emergency works began immediately, followed by recovery works as water levels lowered and the immediate danger had passed.

DWB was retained by MOTI early on in the process to act as Project Environmental Coordinators for over 200 sites. Environmental monitoring services and guidance, as well as environmental assessments and a general environmental management plan were provided during the emergency works. Once recovery works began, DWB continued to provide environmental monitoring services and guidance, as well as extensive consultation with environmental agencies, First Nations, archaeological and other consultants, ministry staff, and engineering consultants. Site and activity-specific environmental management plans were produces as recovery works progressed, in order to provide more specific guidance during works.   


  • Environmental monitoring
  • Environmental management plans for general emergency works, general culvert maintenance works, debris removal, and specific crossing repairs and replacements
  • Environmental permitting
  • Environmental reporting
The floods in the Peace Region required a quick and efficient response in order to deal with the damage and road closures as fast as possible while still encouraging environmentally sound practices. Works included repair and/or replacement of roads, bridges, culverts, and streambanks, as well as channel repair and site reclamation and revegetation. Detour crossings were required at several sites. Recovery works are ongoing, with the repairs and replacements planned in order to prevent future damage and washouts.

Huckleberry Mine Revegetation Trials

CLIENT: Huckleberry Mines Ltd.

YEARS: 2009-2017

A variety of revegetation research projects have been initiated at Huckleberry Mine in the past decade in an effort to identify successful approaches to revegetating soil-capped areas of the mine site. Between 2009 and 2012, seeding trials, which tested a variety of native plant grasses and legumes and soil amendments were established and monitored to identify challenges to re-establishing vegetation cover on disturbed and degraded soils. In 2014, shrub and tree planting trials were proposed to identify a successful and cost-effective approach for establishing native tree and shrub cover on soil-capped areas of the site.

Tree and shrub planting trials were initiated in 2016. A total of 13 species of trees and shrubs were planted in the trials and the trials included the testing of four types of teabag fertilizers (RTI planter paks).

In 2016, DWB became involved in the shrub and tree planting trials by initiating the trials and conducting the subsequent monitoring, soil testing, and reporting services.

 Environmental services provided:

  • Seed collection
  • Seeding prescriptions
  • Revegetation research trials
  • Soil testing
  • Review and monitoring of hydroseeding trial
  • Environmental reporting

Tree and shrub planting trials are ongoing with sampling continuing into 2017 and potentially beyond. Information provided from the trials will assist Huckleberry Mine in re-establishing tree and shrub cover throughout the site as reclamation progresses. DWB has been instrumental in providing the personnel and services required to continue the trials.
