Wildfire Protection

Although it is not something that is on our minds at this time of year, as we turn the corner into spring then summer wildfire protection is something which needs to be considered.  This is particularly important for  landowners near to forest but also grassland areas need to be considered.  Risks vary seasonally based upon levels of snow melt, rain, level of vegetation growth and levels of soil and vegetation moisture.  Good soil moisture levels early in the season followed by a lack of follow up rain results in high levels of fuel from vegetation growth leading to higher potential summer risks from wildfire.  It is worth remembering that even what appears to be a small risk can be heightened by lack of moisture and a quick drying off from high summer temperatures.  Fire spread and intensity on days with low humidity and windy conditions increases the risk to persons and property.

If you live in an area where there is a risk of wildfire now is the time to start thinking about the upcoming season and to prepare for this risk.  There are many management and preparedness actions which can be taken to reduce the risk.

For an assessment of your property for wildfire risk please give us a call.  As Environmental Consultants based in Calgary and Edmonton we service all of Alberta and British Columbia.  Our experience in Wildfire combined with Biophysical And Biological Impact Assessments along with Phase 1 ESA’s allows us to assist our clients with a range of assessments.

Why does the Bank require an Environmental Site Assessment report?

This is an all too common question we get from our prospective clients.  It is a good question as there is an expense involved to the client or seller of the property or whoever may be leasing the property.  In our time undertaking Phase 1 Environmental Site Assessments (Phase 1 ESA’s) in Calgary and Edmonton and right throughout Alberta we have seen many different situations where a Phase 1 ESA assists a client to protect them against liability and risk.

At the bottom of this article is a link to an excellent article by the Business Development Bank of Canada (BDC).  This article outlines a good summary of the aspects of a Phase 1 ESA along with the benefits of undertaking a Phase 1 ESA and the risks of not undertaking such an assessment.  In short however the purpose of a Phase 1 ESA is to evaluate where there is likely to be actual or potential contamination impacting or on a property.  Banks such as RBC, BDC, TD, BMO, ATB, CIBC and HSBC all generally require a Phase 1 Environmental Site Assessment when lending on properties which may have a risk of contamination.  The reason they require a Phase 1 ESA for a mortgage on a property is that the asset under the mortgage, until paid off, is often largely owned by the bank.  Therefore, the aim for the bank is protection to ensure they are not lending money on what may be a liability.  This can occur if for example you are purchasing a property for $500,000 which has a contamination issue with costs for example $100,000 to clean up.  This is why the banks require a Phase 1 ESA.  They wish to limit their exposure to an asset which has significant liabilities.

As a potential purchaser you also want to know if the property you are going to purchase is contaminated.  Whether you are lucky enough to be able to purchase with cash or require a mortgage, if the property is found to be contaminated once you purchase it then you own that contamination.  While in some cases it is possible to chase the previous owner on neighboring owners who may have created the contamination problem this is often fruitless and is extremely expensive.

Sellers of property, particularly commercial properties and farmland benefit from having a current Phase 1 ESA to provide to potential purchasers.  Potential purchasers are often reluctant to spend the money for a Phase 1 ESA on a property if there is a similar property available which already has a Phase 1 ESA report available.  This often enables multiple offers on an industrial property as it is clear to all potential purchasers that the site does not have a risk of contamination being present.

In many cases it is part of a commercial lease agreement that the property is left in the same condition as when the lease was written.  Some leases have clauses that the property must not be contaminated by any activity.  The issue for a business or individual entering into a lease however is that the property may potentially already have contamination present.  As such it is best to always undertake a Phase 1 ESA when taking on a rental lease particularly for a commercial property so you know if the property has been contaminated by a previous tenant.  If you do not protect yourself by undertaking this type of assessment (often as an elevated Phase 1 ESA with some sampling) you run the risk that you may be exposed to having to clean up a site you never contaminated.

So, a Phase 1 ESA represents a sound investment.  As Environmental Consultants based in Alberta and also covering British Columbia we are well placed to service our clients in the West.

What is a Biophysical Impact Assessment or Ecological Impact Assessment ?

A Biophysical Impact Assessment (sometimes called a Biological or Ecological Impact Assessment – BIA or EIA) is an assessment and evaluation of the impact of a proposed project on identified environmentally significant areas, natural parks and natural areas.  These BIA Assessments are used by consent authorities to provide a full background of the Biological and Ecological Values of a site.  Once these values are clearly understood then the full impact on these values can be evaluated and mitigation or compensation can be recommended to reduce the impacts.  These assessments identify environmentally significant areas which often include; wetlands, habitat corridors, rare and endangered plants or animals and their habitats including migratory bird habitat, and Species at Risk.  They provide a background of current conditions and any significant features which need to be considered as part of your proposed development and assist assessing officers in determining any likely impacts to items of significance.  They also allow for mitigative measures to be identified at the project stage.

The information for the background of these reports generally includes:

  • Physical landscape assessment – topography, soil and geology;
  • Hydrology – presence of wetlands and waterbodies such as drainage corridors, streams, creeks, and rivers;
  • Habitat types;
  • Landscape Ecology assessment – wildlife corridors, habitat connections, and any unique features;
  • ANHIC, FWMIS, database research results on the potential presence of listed species at risk, species of special status or rare communities.

Most municipalities have guidelines on what specifically they want considered for these assessments and often they will provide the landowner or their applicant with a letter outlining specific requirements they would like considered.  Often surveys need to be undertaken in the correct season so consideration needs to be given that project planning is critical to assist in achieving project timelines.

The City of Calgary has a Biophysical Impact Assessment Framework which provides details of the various levels of assessment required for various projects and their impacts.  This can be found at:


The Alberta Government also has a guide “Environmental Assessment Program Guide to Preparing Environmental Impact Assessment Reports in Alberta” which provides detailed information about assessment impacts of projects on the natural environment.  This can be found at:

Why do I require a Contamination Report ?

Why do I require a Contamination Report ? (Phase 1 Environmental Site Assessment, Phase 1 ESA or Phase 2 – Environmental Site Assessment, Phase 2 ESA) ? – We are often asked by clients “why do we require an assessment for contamination? (commonly called a Phase 1 ESA or Phase 1 Environmental Site Assessment).  Why do I require a Phase 1 ESA for my bank ?  What is a Phase 2 Environmental Site Assessment ??  What is the cost of a Phase 1 ESA ?

These recent articles provide examples of the impacts of a group of chemicals PFOS and PFOA which in the last few years are drawing increasing concern in relation to human and ecological health.  These articles outline the impacts which can occur from the use of chemicals which were used frequently in the past but were not at the time of use known to be a high risk.  Now however, this group of chemicals is being compared to the DDT of this generation.  In this case the chemical(s) are Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).  These are members of a group of chemicals known as perfluorinated chemicals (PFCs). Both PFOS and PFOA are very persistent in the environment.  They were used in firefighting foams by firefighters and military for many years and often result in contamination to groundwater and soil around the source of their use.  This often includes areas such as airports and training facilities.

There is a great deal of uncertainty about this large group of chemicals which have been used in everything from firefighting foam, non-stick pans (Teflon), water resistant coatings for clothing, shoe waterproofing, cosmetics, and food packaging (like microwave popcorn bags).  They are often passed onto humans via the consumption of various foods including fish and also drinking water.  High levels of PFAS have been linked to negative health effects in animals, including liver damage and stunted neurological development, according to Health Canada. There is little information about the human health risks associated with the chemicals however it is a known endocrine inhibitor.

Where contaminated groundwater is present residents cannot drink their well water or eat home-grown vegetables or eggs from farmyard chickens.  It is not a problem only to Canada and the USA.  In Australia towns near military bases are struggling with supplying water in some areas as the groundwater is contaminated due to the use of firefighting foams.  The use of these chemicals since the 1940’s and their bioaccumulation and stable chemical composition makes them a high risk to human health.  The full impacts of such chemicals are yet to emerge as the research progresses and the available data is in its early stages with much research into the human and ecological impacts continuing.  Groundwater testing should be undertaken regularly to test for contamination by a range of substances which can enter gradually through the soil.  With long lived stable substances such as these migration to the groundwater table can take many years.  As such well water should be tested regularly as contamination may enter the groundwater making a once clean water supply contaminated.

As Environmental Consultants servicing Calgary, Edmonton and British Columbia we come across contamination situations quite often.  As part of any land purchase (just like a home inspection) it is well worth obtaining the services of an experienced environmental consultant to undertake an assessment of the property to determine the potential risk of contamination by way of a Phase 1 Environmental Site Assessment report.  If there is an identified risk of potential contamination then a Phase 2 Environmental Site Assessment should be undertaken to determine if there is contamination present, it type, extent and recommended remediation.  These assessments are a critical part of Due Diligence with any property purchase particularly if it is a ranch/farm, disused piece of land or former industrial site or if the history of the site is uncertain.  The impacts of purchasing a contaminated piece of land can include significant health impacts and significant financial losses through clean-up costs.
