8. Applications Outdoor living Stormwater management Beautification Sustainability and Durability Design Principles Unique character Mimic nature Invoke the vastness of our Earth Depth of color and texture Create uniquely sacred spaces

9. Outdoor living Defining landscape spaces Transforming spaces into outdoor rooms

10. South Minneapolis: Mississippi at Ford pkwy Create a patio for outdoor living Replace concrete walkway Incorporate raingardens Provide for future plantings

11. Chilton Flagstone

12. Patio Area

13. Recycled Concrete Wall

14. Dry Stream Beds Alternative to drain-tile Requires minimal excavation No pipes to get clogged Fall debris enhances aesthetic quality Naturally integrates with raingardens

15. Dry Stream Bed with Flagstone Bridge Integrates flagstone path with the stream bed and raingarden Creates an access for the north side of the yard

16. Covered Stream Bed Disappearing stream maintains the continuity of the walkway Gravel fill prevents clogging or animal damage

19. Minnehaha Creek at Lyndale Create an outdoor entertainment area Integrate stormwater capture and utilization Low maintenance Natural, rustic quality

21. Stormwater Capture and Utilization

22. Initial Excavation

23. 1 ½” Gravel Fill

25. Pump Well

27. Dry Streambed

28. Ready for Flagstone

31. Hideaway at Dark Lake, WI Landscape in harmony with surroundings Incredibly beautiful cabin getaway Create a rustic, old world sanctuary

32. Flagstone Patio with Dry-Stack Retaining Wall

33. Working the Stone

34. Different materials can create unique effects Bluestone path set within Chilton Patio Gives the impression of a stream

35. Transition to a more secluded area Spacing and stone texture control the character of a space

36. Woodland Stairway

37. Stairway Leads to a Secluded Sacred Fire Ring Used stacked flagstone to create an ancient feel Increased joint sizes allow for small plants to grow between stones

38. Size and Color Evoke an Old World Character

40. Minnetonka Ease navigation of hillside Create a durable and ancient landscape

41. Initial Design Contour lines represent a 2’ drop in elevation Nearly 30 vertical feet from back door to lower landing

43. Small Family Landing/Seating Area

44. Seating Wall with Flagstone Caps

45. Challenging Construction No Hill Too Steep

46. Cutting and Burnishing Cutting leaves smooth edges and sides Using an Oxy-Acetelyne torch will burnish off these rough stone faces Leaves a black layer of soot Soot layer washes off in a few weeks

48. Stormwater management

49. Dry Streams and Raingardens Raingarden: A constructed earthen basin designed to accept rainwater for bio-filtration and infiltration into groundwater table.

50. Minneapolis: Nicollet and 35th Small raingarden able to accept enormous amounts of rainwater Avoid hauling away excavated soils

51. Limited Space Raingarden had to accept stormwater from the driveway as well as the roof

52. Excavation and Stream Bed Utilized excavated soil to construct berms around raingarden Trench routs drain tile for trench drain in driveway

53. Integrating the Driveway Installed a trench drain to catch runoff from driveway Raingarden drains over half the property

54. Avoiding Damage to Existing Trees Dry stream bed routs around trees and away from foundation Flagstone bridge maintains path across front yard

55. Finished Product As plants mature, the house will virtually disappear from the street

56. Hudson, wi.: Passive House Arial view of a dry stream bed and raingarden system

57. Constructing the Wall

59. Installing Geo-Textile Geo-Textile prevents soil migration Helps maintain shaping

60. Dry Streambed with Flagstone Bridge

61. “It Works!”

62. Minneapolis: MississiPPi at Ford Pkwy Replaced previous concrete walkway with permeable flagstone system Expanded outdoor living space while installing two large raingardens

63. Removal of old Concrete Walk Removed walk and found original concrete path underneath

64. Stockpiling Stacks of concrete sections to be recycled in retaining walls

65. Recycled Concrete Retaining Wall Avoids cost and pollution Adds unique character and quality Retains berms Controls overflow

67. Dealing with stormwater: Permiable Flagstone Pathway EPDM Liner over landscape fabric Drain pipe in ¾” clear aggregate

68. Completing the System Drain pipe encased in ¾” clear aggregate Downspouts drain directly into the pipe Pipe drains into raingarden

69. Installing the Flagstone

70. New Outdoor Living Space

71. Plantings As plants mature the surrounding neighborhood will literally disappear

72. Roseville: Lake McCarrons Major stormwater challenges Replace turf with No-Mow Sod Stormwater capture via raingarden and drainage swail

73. Residence A Question of Topography Property drains entire neighborhood Sandy soils allow rainwater to flow through soil column

74. Check Dams Drainage Swale Excavation Excavation Residence 4” Drain Tile 12” Catch Basins Raingarden Base Plan

75. Existing Grade ¾” Clear Gravel ±1 Foot Clean-out Access Basement Wall 1.5” Clear Aggregate Excavated Depth: 10” Filter Fabric ±9 Feet 4” Perforated PVC Pipe EPDM Foundation Slab 8 oz. Non-Woven Geotextile Cross Section of Drainage System Capture stormwater from the surface and soil column Seal foundation against stormwater infiltration

76. Excavation

79. Installing Filter Fabric

80. Underlayment and EPDM Liner

81. 1 ½” Gravel Fill

82. ¾” Clear Gravel Top-Dress

83. Catch Basins and Clean-out Access

85. Drainage Swale with Check-Dams Captures surface stormwater Disperses and absorbs flow Plantings w/in swale will provide further permeability

86. Reseeding with No-Mow Fescue Blend of 6 native Fescue Grasses Need no irrigation or fertilization Mimics trad. sod or grows to a wavy, green prairie appearance

87. Ready for Planting
