Technical Studies for 2401 Burnside Road

BC Transit is committed to undertaking all necessary permitting and studies required by Town of View Royal land-use regulations and bylaws.

These studies were prepared for a previous application in 2018. Since that time BC Transit has been reviewing and refining their site plans based on Town and public feedback.  The site concept that was used to inform these studies is being revised.  Where necessary, new studies will be completed.

  Studies for 
2401 Burnside Road
Summary
1.
Archaeological Overview Assessment (currently being reviewed by First Nations)October 2017 Stantec Consulting Ltd.
 
The Archaeological Overview Assessment provides a high-level overview of known and potential archaeological constraints for the study area. This assessment provides an overview of three previously recorded archaeological sites completed in 1995.Recommendations:   An Archaeological Impact Assessment (AIA) is recommended to evaluate the significance and extent of three locations and to identify if other archaeological sites are present within the study area.Further Action: An Archaeological Impact Assessment was completed in April 2018
2. Archaeological Impact Assessment  (currently being reviewed by First Nations)April 2018Stantec Consulting Ltd.
This next level of investigation is an Archaeological Impact Assessment, a permitted field study conducted according to Provincial Standards and methods. It allows an archaeologist to shovel test the study area to examine locations with potential for buried archaeological sites and allows collection of artifacts. It offers a higher level of confidence that archaeological resources, if present will be detected and a higher level of precision in identification of the archaeological constraints. This study was undertaken to assess the potential conflict between the proposed development and archaeological resources and recommend options for managing potential adverse impacts to any sites.
 
Recommendations:Site avoidance is recommended for three locations identified in the AOA. The remainder of the site is considered to have low archaeological potential. Construction monitoring if/where development depth call for soil disturbance to a depth exceeding 1 metre below surface in areas covered by construction fill within 30 metres of Craigflower Creek. First Nations communities should be engaged regarding the sites.Further Action: Further assessment is recommended if the development boundary expands to include areas of moderate to high archaeological potential. Engage with First Nations communities for further discussion and review of Archaeological Impact Assessment. Have an archaeological construction monitoring plan in place including protocols for chance finds or the identification of archaeological evidence exposed during construction.

Phase 1 Environmental Site Assessment

Sept 2017

WSP Canada Inc.

Recommendation: A sub-surface investigation in the form of a Phase 2 Environmental Assessment is recommended at the site to identify on and off-site areas of potential environmental concerns.  

Further Action: A Phase 2 Environmental Assessment was conducted in May 2018.

Phase 2 Environmental Site Assessment

May 2018

Stantec Consulting Ltd.

Phase 2 of an environmental site assessment is performed to assess the potential soil contaminants of concern identified in Phase 1 assessment. This assessment builds on what was identified in Phase l. Issues explored included concentration of arsenic, chromium, cobalt and nickel within the soil. No further groundwater investigation was recommended.
 
Recommendation: Stantec recommended subsequent soil sampling to delineate identified metals contamination in soil in one location on the site.
 
Further Action: Stantec returned to site to collect shallow soil samples.

Geotechnical Summary Report

January 2018 

WSP Canada Inc

The Geotechnical Summary Report outlines the physical properties of soil and rock around a site to inform the design of excavation and foundations for proposed structures and for repair of distress to earthworks and will include surface and subsurface exploration. The testing occurred in five (5) test pits. In general, the test pits encountered fill material including reworked natural fill and construction waste. Generally, native soil was not encountered.

Recommendation: Further geotechnical investigation work is required to determine the extent of fill within the site, characterize the soil conditions, and obtain geotechnical design parameters that will inform civil and structural design of the facilities. 

Further Action: Additional geotechnical work will be undertaken once the final site layout is confirmed.

6.

Subsequent Site Soil Sampling

October 2018

Stantec Consulting Ltd.

Additional soil sampling at the site was conducted to delineate the extent of cobalt and nickel contamination that had been found during the Phase 2 ESA. The previously identified soil contamination is considered to be an isolated issue, and not representative of a larger or site-wide condition.

Recommendation: Stantec recommended no further investigation is required. 

Further Action: A small amount of soil excavated from the location of contamination be disposed of at an approved facility once site development starts.

7.

Noise Impact Assessment

April 2018

BKL Consultants Ltd.

A noise impact assessment is performed to examine the potential noise generated from future operations, its significance relative to local regulatory limits, impacts on neighbouring residences, and recommended solutions to ensure the facility is in compliance. 

The study predicted that an adverse noise impact of 7dba above background noise at one neighbouring location due to exhaust purging noise made by diesel buses and the very low ambient background noise. Several noise mitigation measures were proposed.

Recommendation: Since this assessment was completed, BC Transit has confirmed the fleet will be gasoline and electric thereby eliminating the adverse noise impact of the purging noise (diesel buses only). A quieter backup beeper has also been identified to further mitigate noise impact. Additionally, BC Transit is exploring a site layout on the SW corner of the property (original site layout proposed the NE Corner) to move the noise and activity further away from the residents.

Further Action: An updated Noise Impact Assessment is underway and will be available in Spring 2020.

8.

Riparian Areas Assessment  

October 2017

Stantec Consulting Ltd.

A Riparian Areas Assessment is necessary when the development site exists on or near a fish habitat. This assessment was performed to determine the Streamside Protection Enhancement Area (SPEA) for the three watercourse present. Craigflower Creek is known to be fish bearing, with provincial records of Coho salmon, two forms of Cutthroat trout among others.
The SPEA was determined following the detailed assessment methods established by Schedule 1 of the Riparian Areas Regulation (RAR) under the Riparian Areas Protection Act. This was not a RAR report, only a determination of SPEA. 
 
Recommendation: A full RAR report including danger tree assessments, windthrow, slope stability, tree protection during construction, encroachment and sediment and erosion control will need to be completed.

Further Action: A full Riparian Areas Regulation (RAR) detailed assessment, an environmental management plan suitable for planning and permitting project stages, and a Fisheries Act Request for Review is underway in Spring 2020.

9.

Traffic Impact Study 

April 2018 

WSP Canada Inc

A traffic impact study was carried out to determine the impacts of the proposed development on the pre-existing transportation system, establish the additional traffic generated by the proposed development, and discuss mitigation measures, if required. It was completed prior to the signalization of the intersection at Watkiss Way and Burnside Road.

Further Action: A new Traffic Impact Study is being completed. The report should be available spring 2020.

10.

Wildlife Assessment

November 2017    

Stantec Consulting Ltd.

No occurrence records of rare plants, provincially listed ecosystems, invasive species or wildlife species at risk were identified within the study area.

Recommendation: Project design should preserve the presence of high value habitat in the riparian areas and wetland adjacent to Craigflower Creek and the mature forest in the Northeast corner of the study area. Further recommendation was to position the construction footprint outside the Natural Watercourse and Shoreline Areas. 

Further Action: Adopt best industry practice and incorporate recommendations during the design and construction process.
