BC EAO Condition 39 Exisitng Shoreline Conditions Report – May 2023 – for engagement
The purpose of this posting is to reference the part of the report referring to Metchosin’s coastline and to provide comment on it.

From page 4 of the REPORT:
1 Introduction
As defined by the amendment to Trans Mountain’s BC Environmental Assessment Certificate (EAC) issued by the Province of British Columbia (the Province) on February 24, 2022, Trans Mountain must prepare an Existing Shorelines Condition Report and submit to the Province within 18 months (August 2023) as Condition No. 39.
Polaris Applied Sciences was retained to prepare a report containing shoreline baseline data for shoreline areas closest to spill scenario locations modeled along the marine shipping route and submitted in the Project application. The Province listed the specific scenario locations for the purpose of this study (Figure 1) as:

Strait of Juan de Fuca (south of Race Rocks) (Location G);
Figure 18 shows the Location G – Race Rocks site with the available existing spatial data. Shoreline data are from the Shorezone mapping effort available from the BC Data Catalogue, which show the shore type consisting of rock cliff. Shore-zone Bioband data indicate the presence of barnacles, dark brown kelps, fucus, bull kelp, red algae, surf grass, and Verrucaria. Other data sources indicate offshore kelp beds and multiple seal and sealion haulouts. The Race Rocks Ecological Reserve (RRER) website (https://racerocks.ca/home/) provides more details on ecological resources documented and studied at the site, but not in a spatial format for mapping.
COMMENTS : The exceptionally high Biodiversity of the area and high level of protection since 1980 as a Provincial Ecological Reserve are not reflected at all in the map presented. If one were to look at the Race Rocks Taxonomy presented at https://racerocks.ca/race-rocks-animals-plants/taxonomy-image-gallery/ there may be a better appreciation of the natural capital of this area

Comments:
The reference at the Race Rocks website from racerocks.ca which analyzes the Wind speed from observations of the hourly data provided by Environment Canada show a completely different picture . https://racerocks.ca/race-rocks-lightstation-weather-conditions-environment-canada-problems-for-oil-spill-cleanup/
Some facts from the Environment Canada data:
1. In July of 2022 there were 11 days when the wind speed every hour was 28 km/hr or greater. and 69.5% of the hours in the month, clean up equipment could not be deployed due to high velocity wind conditions.
2. In March of 2023, the wind speed was 28 km/hr or greater 37% of the time.
3. In Februarry of 2023 , the wind speed was 28 km/hr or greater 43 % of the time
4. In January of 2023 , the wind speed was 28 km/hr or greater 36% of the time

================================================
The reality of current speed is that there is a very small window of time during the day that the waters around Race Rocks are not over three knots. In the graph below only in the few hours a day not covered by the white arrows could any boom placement be established. WHen looked at from this perspective, added onto the small windows of time when the wind speed is under 28 km per hour could spilled oil containment even be possible.

From page 28 of the Polaris report
Field surveys were not conducted at Race Rocks due to the long lead time in acquiring a “research” permit from BC Parks to access the Ecological Reserve. Information detailed below comes from reviewing the existing data available, Google Earth, the RRER website, and a First Nations representative.
The shoreline at Race Rocks, specifically Great Race Rock, appears to be mostly bedrock cliff, ramp, and platform, possibly with some small pocket pebble/cobble beaches. Bedrock cliffs and ramps are observable in Figure 21 which show some example photographs from the Race Rocks Ecological Reserve website. The backshore appears to be mostly bedrock with some vegetation.
An active lighthouse along with several other buildings are present. Pearson College UWC conducts research and teaches classes at the site. Whale and sightseeing boats frequent the waters around Great Race Rock and are visible from photographs on the Race Rocks website and on Google Earth.
As mentioned before, Race Rocks is a BC Parks Ecological Reserve which are “areas selected to preserve representative and special natural ecosystems, plant and animal species, features and phenomena. Scientific research and educational purposes are the principal uses of ecological reserves”7. A wide variety of ecological resources are documented, tracked, and studied at the site. This documentation includes a weekly animal census, annual bird counts, and an entire list of species ever documented with photos/videos since 2000 (https://racerocks.ca/race-rocks-animals-plants/taxonomy-image-gallery/). Additional research conducted at the site can also be found on the RRER website. The extensive use of the site as a haulout location by pinnipeds is documented on the website and visible on Google Earth.
This area has historically been used by First Nations for harvesting food, as documented on the Race Rocks website, and a First Nations representative indicated that fishing is common in the waters around the site. Burial mounds/cairns have been researched and documented on Great Race Rock.
A helicopter pad is located near the lighthouse.
Based on the available data, and without visiting Race Rocks, the Shorezone mapping appears to be relatively accurate. The detailed observation of the flora and fauna on the Race Rocks website and other research conducted by Pearson College provides the most thorough documentation of the ecological resources present compared to any of the other sites visited.

On February 9, 2023 Deidre Chettleburgh and her grandson Ben retrieved this 37 cm wolf eel from the strand line on Taylor beach.
Although the experts on iNaturalist identified it as a wolf eel, (https://inaturalist.ca/observations/148414762 ) this description of a juvenile wolf eel from Wikipedia doesn’t really fit . ???
“Younger wolf eels are orange with big dark spots in the posterior part of the body. Once older they turn grey, brown greyish or dark olive.”[7][8]
This individual was very dark black. Also in my many years of Diving around Race Rocks Ecological Reserve I never saw anything like it.

Link to Fish of Metchosin Coastal
The determination of the natural boundary of the coastline is important in establishing ownership of property and therefore public access along a coastline: The following reference may help clarify this .
Over the past year a volunteer group has worked with CRD Parks staff to restore some of the sensitive habitat at Witty’s beach and lagoon.
It is important to observe the signage and avoid walking in this area.
In the fall of 2021, a cliff stabilization exercise was carried out along with the re-establishment of the stairway down to Witty’s Beach . Cuttings of willow were planted in the area of the back that had been eroding.
