Environmental Impact Assessment: Garibaldi at Squamish

For our last lab, we were conducting the environmental assessment on the project, Garibaldi at Squamish (GAS), a purposed year-round mountain resort located on Sea- to Sky Highway and it is 13 kilometers north of the district municipality, Squamish.

Memo – Garibaldi at Squamish Environmental Impact Assessment.

The site is 45 kilometers apart from the 2010 Winter Olympic site, the Whistler-Blackcomb resort and 80 kilometers to the region largest city, Vancouver. The resort will be including multiple ski lifts, ski pistes, resort accommodation, ground water supply system, infrastructure and other recreation facilities in the total project area of 2,759 hectares (GAS project Assessment Report, 2016).

As the natural resource planner for the proponent, Garibaldi at Squamish Inc., my duty is critical evaluate the concerns raised from our competitor, Squash Nation, and local residents. In this environmental assessment, the project area is primarily evaluated by the spatial analysis software, ESRI ArcGIS, and we have identified the potential environment aspects that may affect by the GAS in the project boundary:

  • Rivers and fish habitats
  • Old-grown forest area
  • Red-listed plant species
  • Ungulate habitats

At the same time, the analysis map indicates the area below elevation of 555-meter level which may consider as the bottom line for building ski resort in British Columbia according to a 1974 report. The area size for each aspect of environmental impacts also calculated as following statistics:

  1. Project area below 555m vertical: 1,637.74ha/ 29.94%
  2. Project area with river and fish habitats: 1,423.29ha/ 26.02%
  3. Project area with old grown forest existing: 371.03ha/ 6.78%
  4. Project area with red-listed species: 1,358.46ha/ 24.84%
  5. Project area with Ungulate winter habitats: 431.52ha/7.89%

    Figure 2: Map of Red-listed plant species distribute within the project boundary.

The spatial distributions of each category have shown in above diagram. We can recognize that most of the red-listed species are grow adjacent to the main branch of the river that is located below the 555-meter line. The ungulate habitats are either close to the 555m contour line or on the project boundary. Although many small streams, headwater are scattered across the higher elevation, but there are less concerns for the fish species due to steep falls of streams which make it difficult for fish to swim back. However, the old grown forest sites are widely spread, their presences are more common toward the northern part of the project area. Base on evidences above, we have come up with few recommendations to guide the project planning in order to mitigate and minimized the impact on the local ecosystem. First, although the protected areas seem as big as the project area if we add up the percentage, in fact, there are about 52.65% is actually considering as the protected area because of the overlap. Secondly, the GAR should avoid constructing ski facilities and housing unit in the low elevation area (<555m). It will be more sustainable for the ski resort to build at higher elevation with colder environment, also place around the river basin is concentrated with vulnerable but significant ecological region and the developer must not disturb. When planning the ski runs, the proponent must agree not to develop the existing ungulate habitats and old-grown forest. Despite the head streams are usually small in scale, yet the proponent facility should avoid interruptions on the flows of water which is important for the main river’s influx.

In conclusion, the proposal project, Garibaldi at Squamish, should be approve by the government authorities. As the natural resource planner of the project, we had carefully assess the proposed land by conducting environmental impact assessment in the project area. Our construction will be refrain from ecological sensitive ground, for example, the existing protected areas and place below 555m according the E.A. result diagram.

As a GIS specialist, we may often receive some projects that we don’t ethically believe in but our clients require us to do our best for their benefits. These circumstances may be quite frustrated for some people, for example, when you working for controversial project proponents such as Woodfibre LNG project in Squamish and Kinder Morgan pipeline etc. In the workplace, when I involved in these proposals that I don’t match my personal believe or opinions, it is hard to tackle because we always constrained by the interests of the client. So in these cases, I may try to contact and pose some critical questions on the project while having the conversation with people from proponent side. If they demonstrated convincing evidence or solutions for the environmental concerns I raised, I will still stand on their side as long as the project does not show significant threats to the local community and involving illegal acts.

Quantitative Data Classification

The journalist and a real estate agent may choice two different classification methods to display because the former wants to objectively present the truth in a news yet the latter is thinking that how to increase their sales as much as possible. Since the roles have different approaches, if I’m a journalist, I will use Manual Breaks classification to present. First, the interval values are easy to understand, people generally have better understanding on housing prices that are in integers (e.g. $500,000, $1,000,000) rather than random numbers (e.g. $1,201,347). Secondly, the price ranges (intervals) are more appropriate to present the distribution of housing cost compare as to the Equal Interval classification because it shows what close to the reality of the Vancouver housing market. However, the real estate agent may choose the Equal Interval map to put on his/her flyers or website. The graph actual makes the properties in Vancouver seem more affordable than it should and we all know that’s not the truth. This is due to the intervals are much larger in this classification ($600,673 in each price ranges) and also result the average properties prices in UBC fall into the second-cheapest categories in the scope of the entire Vancouver market. Also, the data I using to present is from 2011, so it’s pretty much dated. Since then, housing affordability in Vancouver has sharply decrease because of the inflating properties price within the city. Therefore, the 2011 data cannot properly present the nowadays housing market in metro Vancouver.

City of Vancouver Areas Under Tsunami Threat

List of the Education facilities within the Vancouver danger zone:

  • St. Anthony of Padua
  • Ecole Rose Des Vents
  • False Creek Elementary
  • Emily Carr Institute of Art & Design
  • Henry Hudson Elementary

List of the Healthcare facilities within the Vancouver danger zone:

  • Falso Creek Residence
  • Broadway Pentecostal Lodge
  • Yaletown House Society
  • Villa Cathay Care Home

How to find the upon information?

Starts with the ArcToolbox, under the Analysis Tools, expand the Overlay button then select Intersect. Then choose the existed Vancouver Education/ Healthcare layer to intersect with Vancouvermask_Danger and new layer(s) will create. Right click the layer(s) and then open the Attribute Table, you will now find the list of facilities that fall in the danger zone.

The new location for the St.Paul’s Hospital will be place on the false creek flat, which was a tidal area that has been reclaimed from sea in 1910’s.  Due to its low elevation and proximity to the water body, the area is expose to protential risk of flooding by tsunami or land liquefaction in major earthquake events.

How to fix misaligned and improperly referenced spatial data

It is important to find an appropriate spatial reference data for a specific coordinate system to get the correct display result. Improperly reference spatial data in some files will result misalignments of geographical locations which cause differences in distance between two coordinates. In order to fixed this issue, we need to pick the correct datum and geographical/projected coordinate systems.

  • Check all the layers’ Properties on the Table of Content
  • Scroll down to the Source and look at the Spatial References
  • Record the Coordinates System and Datum info see if they all match.

If the coordinate system is missing, you will need to…

  • Remove the original files from the Table of Content
  • Launch the properties tab of the file on ArcCatalog
  • Find the XY Coordinate System and click on the Geographic Coordinate Systems.
  • Then under North America folder change it to NAD 1983 and press OK
  • Finally, add back the file
