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.
The Goal To demonstrate practices homeowners can implement to reduce the volume of storm water flowing off their property.
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
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
Impacts of Increased Runoff Volumes $ $ $ $ $ $ $ $ $ $
A combination ofpractices that… • Increase infiltration • Better manage runoff & promote “run-on” • Decrease impervious surfaces
Increase Infiltration • Reduce soil compaction • Landscaping alternatives • Turf management
Porosity of Urban Lawns = 30% The avg. porosity of a compacted building pad = 30%
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
Reverse Soil Compaction on Existing Homes: Aerate Your Lawn
Reverse Soil Compactionon Existing Homes: Plant Trees
Permeability Rates Study completed in Ocean County, NJ – March ’01
Minimize Soil Compaction on New Homes: Avoid Compaction Tree Protection Area
Minimize Soil Compaction on New Homes: Break-up Compaction
Increase Infiltration:Turf - Let it Grow Tall Plant Height Root Depth
Better Manage Runoff & Promote “Run-on” • Disconnect gutter downspouts • Collect storm water • Maintain open swales and ditches • Slope impervious areas
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.
Roof runoff is piped from downspout to a dry well. Be sure to check with your local jurisdiction for rules pertaining this.
Rain Collection Barrel – use for watering gardens
Road-side ditches absorb more water than culverts Open Ditch Enclosed Ditch
Grassed swales absorb more water than culverts Culverted Swale Grassed Swale
Typical Sloping Driveway Drains directly to the road
“Crowned” Driveway Drains directly to the lawn
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
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”
