Botanical Garden Feasability Study Botanical Garden Feasability Study Presentation Transcript

  • Botanical Garden Feasibility Study May 5, 2008 Township of Langley, BC LEES + Associates Township of Langley
  • Erik Lees Catriona Hearn Heidi Redman Who are we? OUR TEAM LEES+ASSOCIATES Landscape architects and planners G.P. Rollo & Associates Land Economist Botanical and Horticultural Consultant Paul Rollo Douglas Justice
  • What was our process? PHASE 1 : Review of exemplar gardens PHASE 2 : Site selection Criteria PHASE 4 : Financial Analysis PHASE 5 : Final Report and Recommendations PHASE 3 : Opportunities and Constraints
  • PHASE 1 What is a botanical garden?
    • Have played evolving roles throughout history.
    • Today, botanical gardens are called upon as key players in plant conservation and education.
    • In 2000, the UN recognized botanical gardens as playing an important role in the conservation of plant diversity.
    • No agency gives legal accreditation to botanic gardens – anyone can call any garden a botanic garden.
  • What is an arboretum?
    • An arboretum is “a specialized collection of woody trees and shrubs that are cultivated for scientific, ornamental, or other education purposes.”
    • - American Public Gardens
    • Association
    • Like botanical gardens
    • there is no certifying body
    • for arboreta.
    PHASE 1
    • Documented collections with species of known provenance;
    • Aesthetic display, public education;
    • Conducts scientific research on the collection;
    • Is open to the public;
    • Employs at least one professional staff member (paid or unpaid).
    Criteria for a botanical garden PHASE 1
    • Contains documented collections with species of known provenance;
    • Provides educational and aesthetic display;
  • Garden Exemplars
    • Tofino Botanical Gardens ( Tofino, BC)
    • UBC Botanical Gardens (Vancouver, BC)
    • Van Dusen Botanical Garden (Vancouver, BC)
    • Swan Lake Nature Sanctuary (Saanich, BC)
    • Horticulture Centre of the Pacific (Saanich, BC)
    • Centre Creek (Surrey, BC)
    • Milner Gardens and Woodland (Qualicum Beach, BC)
    • Minter Gardens (Chilliwack, BC)
    • Darts Hill Garden Park (Surrey, BC)
    • Royal Botanic Gardens (Hamilton, ON)
    • Devonian Botanic Garden (Edmonton, AB)
    PHASE 1
  • Site Selection Criteria 1. Size: a minimum of five hectares. 2. Soil Capability: friable, well-drained, weed and disease free soils. 3. Spatial Context: connections to residential neighbourhoods; appropriately zoned; a range of environmental conditions and habitats on site . 4. Infrastructure: serviceable with access/egress, parking, circulation, irrigation and potable water, sanitary and hydro. 5. Views: provide scenic views; if possible, direct access to water. 6. Landscape Character: an area that reflects the natural character of Langley. PHASE 2
  • Assessment of candidate site PHASE 3 Proposed site at 21200 block Fraser Highway
  • Opportunities & Constraints
    • Opportunities:
    • Lookout to creek and fish spawning
    • High visibility
    • Proximity to Kwantlen and Trinity Western
    • Potential for salmon habitat partnerships
    • On proposed Arbour Ribbon
    • Opportunity for expansion
    • Scenic views to surrounding area and northwards across the region.
    PHASE 3
    • Constraints:
    • Silty/clay soils with poor drainage
    • Airport height restrictions and future expansion of airport
    • No existing buildings or facilities
    • Possible access issues off Fraser Highway
    • Beavers present on site
    • Lack of topographic variation
    • Some plant families will not tolerate site
    • Noise from highway and airport traffic.
  • Soil Analysis PHASE 3 Bill Herman, Pacific Soil Analysis
    • Soils on site are predominantly a finely textured silt (78.2%) with poor drainage capabilities.
    • Considered unsuitable for growing a broad variety of temperate species.
    • An amendment of 2 parts river sand for every 1 part of existing soil would improve the soil, but would exacerbate summer drought conditions.
  • Financial Analysis PHASE 4 Scenario 1: Traditional Botanical Garden: A traditional botanical garden requiring the highest level of organizational capacity, capital resources, and institutional commitment. Scenario 2: Sustainable Horticulture Centre: A public garden with a focus on stewardship of local wetlands, sustainable horticulture and urban agriculture, and aesthetic display. Requires mid-level organizational capacity, capital resources, and institutional commitment. Scenario 3: Wetland Arbouretum: A public nature park and arbouretum, with a focus on wetland ecology and the interpretation of the Langley prairie requiring the least amount of organizational capacity, capital resources, and institutional commitment.

  • Financial Analysis PHASE 4 Summary of 15 Year Totals 1,522,234 1,712,641 2,991,478 Total Operating Subsidy 863,101 1,069,204 2,143,808 Total Capital Costs 1,566,351 1,817,698 2,852,993 Total Operating Costs 1,081,617 1,405,716 2,709,109 Total Revenue Year 15 Year 15 Year 15 9.0 Year 15 Totals (Cumulative) Scenario 3 Scenario 2 Scenario 1
  • Next Steps PHASE 5 Although a classic botanical garden is not recommended as feasible, an alternative garden model may be a viable option. It is recommended to initially pursue Scenario #3 Wetland Arbouretum, with the intention of developing Scenario #2 Sustainable Horticultural Centre when there is sufficient interest and funding.
  • Next Steps PHASE 5
    • 1. Adopt a formal vision for a public garden.
    • 2. Undertake a business plan for the garden.
    • Integrate the business plan and the site selection criteria.
    • 4. Consider the lands at the 21200 block of Fraser Highway with possible annexation of the rural farmland south of this location.
    • Construct a building on site to serve as an interpretive centre/ classroom/office.
    • Document any plant collection developed on the site with acquisition and provenance records.
    • 7. Form a non-profit society to oversee operation of the garden.
