2 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.

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

4 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

5 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

6 Runoff Generated by 1” Rainfall over 1-acre Parcel

7 Impacts of Increased Runoff Volumes $ $ $ $ $

8 A combination of practices that… Increase infiltration Better manage runoff & promote “run-on” Decrease impervious surfaces

9 Increase Infiltration Reduce soil compaction Landscaping alternatives Turf management

10 Soil Compaction

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

12 Reverse Soil Compaction on Existing Homes: 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. Add Compost

13 Reverse Soil Compaction on Existing Homes: Aerate Your Lawn

14 Reverse Soil Compaction on Existing Homes: Plant Trees

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

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

17 Minimize Soil Compaction on New Homes: Tree Protection Area Avoid Compaction

18 Minimize Soil Compaction on New Homes: Break-up Compaction

19 Increase Infiltration: Landscape Alternatives

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

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

22 Typical Gutter Downspout

23 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.

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

25 Rain Collection Barrel – use for watering gardens

26 Road-side ditches absorb more water than culverts Open DitchEnclosed Ditch

27 Grassed swales absorb more water than culverts Grassed SwaleCulverted Swale

28 Typical Sloping Driveway Drains directly to the road

29 “Crowned” Driveway Drains directly to the lawn

30 Decrease Impervious Areas: Pervious Alternatives

31 Decrease Impervious Areas: Building Up vs. Out Type of House Living Space Roof Area Runoff from 1” Rainfall Ranch (1-story) 2000 ft 2 1250 gallons Colonial (2-story) 3000 ft 2 1500 ft 2 938 gallons

32 Top 5 Practices to Implement on 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

33 Top 5 Practices to Implement on 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”
