About Ms. Clarke

 

Biography

Ms. Clarke is a Professional Geoscientist with undergraduate and post‐graduate
education in physical geography (geomorphology) and approximately 17 years of
consulting experience. Areas of specialization include: terrain analysis, hillslope
geomorphology, slope stability assessment, natural hazard assessments, watershed hydrology, and environmental impact assessment.
Ms. Clarke is the Director of Clarke Geoscience Ltd., an independent consulting firm based in Kelowna, BC, providing specialist services in earth science and water resources. She provides reliable experience and a multi‐disciplinary perspective.

Areas of Key Experience include:

Terrain Analysis and Stability Assessments
Completed and managed numerous terrain assessment projects for forestry (roads and cutblocks), oil & gas (pipeline and road), and land development throughout BC. Work included the interpretation and analysis of air photos, field confirmation, data analysis and reporting. Project scales vary from an overview‐level analysis to detailed ground based site assessment. Example projects include:
  •  Geotechnical stability assessment of slopes within a Canadian Wildlife Refuge (Wilmer Marsh) where access to, and remediation of, an historic waste dump would potentially compromise slope stability (SLR Consulting (Canada) Ltd.)
  • Terrain stability field assessments for proposed cutblocks in the Mission Creek watershed and Belgo Creek, Kelowna, BC (Drake Forestry and BC Timber Sales)
  •  Developed and instructed a fourth‐year Earth and Environmental Science Terrain Analysis course at the University of British Columbia – Okanagan, including methods for terrain mapping and stability assessment.
  •  Detailed terrain stability assessments for approximately 25 km of proposed natural gas pipeline in the Kiskatinaw River area south of Dawson Creek, BC for EnCana Corporation.
  • Detailed terrain stability assessments for twenty‐six kilometres of proposed road in the Lillooet Forest District (various locations ‐ BC Timber Sales).

Hillslope Hazard Assessment
Completed and managed site‐specific assessments of natural hazards for residential and recreational land use development. Recommendations for impact mitigation were provided where necessary. Example projects include:

  •  Debris flow hazard and partial risk assessment for residential property on Fransen Creek, near Shuswap Lake (owner)
  • Slope stability assessment for the Lebanon Creek Linear Trail, Kelowna, BC (Regional District of Central Okanagan)
  • Rock fall risk assessment for the Hardy Falls Regional Park trail to assess risk to trail users, Peachland, BC (Regional District of Central Okanagan)
  • Debris flow assessments of Sicamous Creek (Waterway Houseboats) and Old Town Creek (Twin Anchors Marina) for large marina resort developments near Sicamous, BC
  •  Completed a flood hazard risk assessment and Development Variance Permit applications for numerous land development proposals in the Okanagan, including a proposed subdivision along Bolean Creek, Falkland, BC and several single‐family residential properties adjacent to streams or lakes.
  • Conducted debris flow and flood assessments for the purposes of a Development Variance Permit for residential properties along Hummingbird Creek, Swansea Point, BC
  •  Delivered in‐house technical training seminar with respect to debris flow fan recognition (air photo and field indicators).
  • Conducted assessments for resource roads (1000’s km), including soil surface erosion potential assessments, prescriptions for road deactivation, and sediment source surveys for large (1000’s km2) study areas. 

Watershed and Hydrological Assessment
Completed numerous watershed assessments throughout interior and coastal BC, which included determining hydrologic response to forest harvest, roads, and other land use activities and processes such as Mountain Pine Beetle infestation. Example projects include:

  • Okanagan Community Watershed Risk Assessment for seven (7) watersheds to assess Mountain Pine Beetle effects on hydrology and water quality (Ministry of Environment)
  •  Watershed assessment for proposed residential development, Gold Creek, Cranbrook, BC.
  • Expert witness technical review of hydrology report alleging damages associated with historical agricultural land development, Quesnel, BC.
  •  Argenta‐Johnson’s Landing Watershed Inventory and Hydrological Assessment,Kootenays, BC for BC Timber Sales, which comprised an assessment of hydrologic risk in an area containing numerous springs and domestic water intakes.
  • Chapman Creek and Gray Creek CWAP (1999) and CWAP update (2006), high profile community watersheds in Sechelt, BC.
Other related work includes:
  • Completed a Drought Management Plan for Greater Vernon Services including development of drought forecast indicators, triggers, and responses specific to municipal water use.
  •  Working with a wildlife biologist, completed an Aquatic and Hydrology Baseline Study for the Merritt TSA including literature review on hydro‐riparian relationships in an effort to prioritize watersheds for future monitoring in light of pine beetle infestation.
  •  Implemented a three‐year water quality and quantity monitoring program on the Theodosia River, a river impacted by a flow diversion. Work included flow monitoring, sampling, maintenance of a remote monitoring station, and reporting.
  • Completed in‐stream and upslope watershed‐level restoration plans for several watersheds in BC.
Stream Channel Geomorphology
Completed air photo and field assessment of stream channel stability and developed
rehabilitation plans. Assessments completed for approximately forty (40) different
streams/watersheds and often completed in conjunction with biological and ecological assessments. Example projects include:
  • Prepared designs for stream channel realignment and habitat compensation designs for a development in Union Bay, Vancouver Island (SLR Consulting (Canada) Ltd.).
  • Channel stability assessment of portion of Mill Creek through the Kelowna International Airport, Kelowna, BC to address concerns for channel aggradation and overbank flooding (City of Kelowna).
  • Prepared preliminary designs for the realignment and restoration of a 1.5 km section of Vernon Creek around a proposed extension of the regional airport runway (City of Vernon).
  • Conducted assessments and prepared restoration designs for the realignment and restoration of a small stream for a private landowner (Kelowna).
  • Watershed‐scale assessments of stream channel condition in logged areas. Including: Ryan River, Pemberton, BC (Terminal Forest Products Ltd.); Kokish River, Port McNeill, BC (TimberWest), and five watersheds in the Merritt Forest District, Merritt, BC (SBFEP).
Environmental Impact Assessment and Related Work
Contributed to, or managed, Environmental Impact Assessment projects, including the completion of Environmental Management Plans and Erosion and Sediment Control Plans (ESCPs) and conducted and/or supervised on‐site environmental monitoring during construction. Project experience includes:
  • Technical input to a CEAA Screening assessment of proposed expansion of Canadian Helicopters facility at Penticton Regional Airport, Penticton, BC.
