Tools

  • Contractor's site level - shoots vertical intervals - drop in stairstep. Vertical intervals are equal unless there is huge variation in slope. Contractor's level is by Berger at Home Depot.
  • Laser level - online - quickest is Forestry Supply has good options. Robust. No hassle. Self-leveling laser - where you don't have to do a bubble to level. Must have 360 deg compass on it. Laser shoots 360 degrees. Shoots lo less than 1000 feet in shooting length. TopCon brand.
  • Stick - Forestry Supply - 16' stick. Reads in 10ths of inch. Read the back of it, so distance from ground rather than absolute.
  • Weedwhacker + chainsaw. Offset 10' from trees if trees are in the way.
    • Always go in one direction.
    • Need a scale map of property.

Procedure

Shoot vertical intervals first (slope). Set up horizontal intervals (following contours, creates aspect) later. Then put the grid down.

  • 50 ft. grid, starting at SW Corner, working South to North, then West to East
  • When grid is complete, transfer information to Sketchup
  • 25 ft. grid, starting at SW Corner, working South to North, then West to East
  • Detail grid transferred to fill in Sketchup rough survey.
  • 2 foot drop standard. May need to 4' at high slope like 10%.

Design

Design: 5% slope not good for animals, west face not good.

Initial thoughts:

West strip

  • more water, shade
  • less erosion
  • more established creeks
  • proposed use: homesteads, collective gardens, ponds, water storage

East strip from S to N end

  • Workshops
  • large-scale storage (pole barns, tractor garages)
  • greenhouses
  • orchard/food forest (swales, trees, vines, edible groundcover)
  • Ponds where there is good catchment (directly NW of orchard looks practical, as well as just N of the old workshop)
  • pasture (organic shapes with edible fence following swales on contour)
  • grazeland rotated by species, with cover crop and grain rotated seasonally
  • rain catchment on animal shelters
  • some shade trees planted
  • water storage at top of slope, gravity-fed water troughs for animals

Native Trees

  • remove ones with less utility, to be turned into biochar, lumber
  • remove deadwood, leaving some logs to be inoculated with mushrooms
  • Forested center space:
    • Pond at north end, continuing into creek with ponds coming down the slope
    • Pigs fenced in with palettes, left to forage and free range, fed the byproducts of civilization (whey, food wastes, fallen nut crop)
  • Keepers: mulberry, elder, walnut, oak


Ask Parker on full soil report.
