Market Research:Lot-level Stormwater Control in the Residential Sector
Residential Surveys• Landscape = reflection of
themselves, beauty being the most important aspect, pride, clean, tidy
• Lawns given the highest importance, gardens, trees then driveways
• Sustainable landscaping or Eco Landscaping was perceived to be giving up decks, BBQ, color/beauty = LOSS
• 44% of respondent didn’t know what a watershed was
• When asked to name 3 Native Plants:
dandelions, trillium, and no answer
