  1. Reducing Storm Water Runoff on Your Homesite 6090 Wedgewood Road Medina, OH 44256 330-722-2628 (phone) 330-725-5829 (fax) Local leadership for soil and water conservation.

  2. The Goal To demonstrate practices homeowners can implement to reduce the volume of storm water flowing off their property.

  3. Natural Areas • Many air and water • pockets • Numerous micro • and macro • organisms • Deep plant root • growth • High surface • water infiltration • and detention • Low surface water • runoff and erosion

  4. Developed Areas • Few air and water • pockets • Limited micro and • macro organisms • Shallow root growth • Low surface water • detention and • infiltration • High surface water • runoff and erosion

  5. Runoff Generated by 1” Rainfall over 1-acre Parcel

  6. Impacts of Increased Runoff Volumes $ $ $ $ $ $ $ $ $ $

  7. A combination ofpractices that… • Increase infiltration • Better manage runoff & promote “run-on” • Decrease impervious surfaces

  8. Increase Infiltration • Reduce soil compaction • Landscaping alternatives • Turf management

  9. Soil Compaction

  10. Porosity of Urban Lawns = 30% The avg. porosity of a compacted building pad = 30%

  11. A study completed in Seattle, WA showed the addition of compost amendments to urban soils reduced runoff from 29-50% over soils with no amendments added. Reverse Soil Compactionon Existing Homes: Add Compost

  12. Reverse Soil Compaction on Existing Homes: Aerate Your Lawn

  13. Reverse Soil Compactionon Existing Homes: Plant Trees

  14. Permeability Rates Study completed in Ocean County, NJ – March ’01

  15. Tree Canopy Cover Study:Garland, TX – 3.86 acre site

  16. Minimize Soil Compaction on New Homes: Avoid Compaction Tree Protection Area

  17. Minimize Soil Compaction on New Homes: Break-up Compaction

  18. Increase Infiltration: Landscape Alternatives

  19. Increase Infiltration:Turf - Let it Grow Tall Plant Height Root Depth

  20. Better Manage Runoff & Promote “Run-on” • Disconnect gutter downspouts • Collect storm water • Maintain open swales and ditches • Slope impervious areas

  21. Typical Gutter Downspout

  22. Disconnected downspouts direct roof runoff away from the foundation and into the lawn. Be sure to check with your local jurisdiction for rules pertaining this.

  23. Roof runoff is piped from downspout to a dry well. Be sure to check with your local jurisdiction for rules pertaining this.

  24. Rain Collection Barrel – use for watering gardens

  25. Road-side ditches absorb more water than culverts Open Ditch Enclosed Ditch

  26. Grassed swales absorb more water than culverts Culverted Swale Grassed Swale

  27. Typical Sloping Driveway Drains directly to the road

  28. “Crowned” Driveway Drains directly to the lawn

  29. Decrease Impervious Areas: Pervious Alternatives

  30. Decrease Impervious Areas:Building Up vs. Out

  31. Top 5 Practices to Implementon an Existing Home • Let grass grow taller • Maintain all open drainageways (ditches & swales) • Disconnect downspouts and/or use a rain barrel or cistern • Aerate your lawn • Plant trees & shrubs

  32. Top 5 Practices to Implementon a New Home • Prevent soil compaction during construction • Add organic amendments to your soil • Plant trees & shrubs • Disconnect downspouts and/or use a rain barrel or cistern • Promote “run-on”
