Design Phase1 Observation
“Dozens of useful strategies may evolve from your first simple observations, and
the site begins to design itself.”
Key site Observationssoil poor drainage clay
compaction
run-off erosion rill
gullyspace slope a lot of water
Needed: Soil Building
• Hugelkultur Mounds• Mulching• Compost
Needed:Soil stabilization
• Cover crops • Grade the field to level• Redirect water into storage zones
Needed:Drainage & Water Storage• Berms
Direct Water• Swales
• Pond Store Water
• Water garden
Altogether…1. Hugelkultur, mulching, compost to
build soil2. Level field, plant cover crops to
stabilize soil3. Use berms and swales to manage
water
Design Phase II: Zonation
“Zoning is about correct placement- positioning things based on intensity of use; Zones can be
thought of as a series of concentric rings moving out from a center point, where human activity and need for attention is most concentrated, to where there is no need for intervention at all...”
Zone 1:
Education Area
Where permaculture principles are applied in creating a harmonious, sustainable environment in which to work, learn and play.Water
Storage
Area requiring frequent attention
and visiting.
Zone 2: Greenhouse Area Zone 1
Zone 2 Cover Crops
This is the wall of dirt outside the greenhouse door and to the south. The brown dotted lines represent the top and bottom of the sloped wall. These plants are edible, shade tolerant and will grow in poor soils on a steep slope.
Zone 3: Main Planting Beds
12 3
Features of
Plant Beds
1. Single Till: Till one time and not again; Do not step on planting areas to minimize compaction
2. Mulched: Add hay, straw, leaves, clippings; Allows soil food web to thrive, cools soil, prevents weeds
3. Low Hugelkultur: contributes to soil nutrients and irrigation is less necessary or unnecessary
4. Keyhole beds: located at the corners

along the periphery• 5. Center: Tree Guild, Seating, or Bed

Water “The main concern is water, as it is both
the chief agent of erosion and the source of life for plants and animals.”
Water FeaturesGoal: Redirect excess water from Zone 3 to Zone 1, for storage in the pond.Strategy: Build up berm downhill from baseball field– 3 feet rise
• Direct water towards the pond with a ditch/stream.• Possibility: Build a bridge over the ditch or a dam to
further control water flow.
