Presentation Transcript

  1. Rain Gardens: A proposal by the Accept the Greener Challenge Club

  2. Accept the Greener Challenge Club • Created 5 years ago • APES top 10 recommendations • Reduce energy consumption • Solar for heat and energy • Cisterns and rain gardens • 100 members (15% of student body)

  3. Water Quality in the Ellerbe Watershed • High levels of nitrogen and phosphorous lead to algae growth • Algae depletes oxygen, killing the wildlife.

  4. The Location of Ellerbe Creek Impervious surfaces are buildings and gray roads/walkways.

  5. Rain Garden Proposal • Corner of Hunt – catches 25% of water from Hunt roof • 362 ft2 – 6 in deep • Total approximate cost for excavation, mulch, soil amendment (sand), and plants: $2,170 • Partial cost we pay: $543

  6. How Rain Gardens Work • Water collects in rain gardens and is filtered through the soil. • Lessens polluted runoff water that enters waterways.

  7. Meeting Clean Water Requirements • EPA requirements for the Falls Lake Watershed: • 20% reduction in total nitrogen by 2016 • 40% reduction by 2036. • Proposed rain garden will remove: • .28 lbs Nitrogen/year, .03 lbs Phosphorous/year

  8. What We’re Asking • Permission • “No Cuts” called by Maintenance • Excavation help from Grounds • Long-term commitment • Funding Options • ~$543 needed for plants • Possible funding to cover what a grant for 25% of total cost does not

  9. Future Goals • Implementation of additional rain gardens • Cisterns on Hunt and PEC • Control storm water runoff at NCSSM • 42,230 gallons of storm water runs off Hunt roof each year • Used to water and fertilize fields • Creek Remediation • Big Sweep-Ellerbe Creek clean-up • Cool water entering creek from the boiler
