Surveying 101

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 for Grid Method

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

• Find steepest slope, lay 2 foot intervals
• 2 foot drop standard. May need to be 3' or 4' at high slope like 10%.
• 25' terrace is the guiding criteria, but if it's steeper then the terraces might have to be as narrow as 10'
• Result: Looking for smooth arcs of 100'
• Put in contours every 20' using rotating laser level and transmitter

Grid:

• 100' grid, using transit level and 2 compasses (because one might be corrupted)
• Number/label squares on grid, write on a map
• For each square you will be able to tell slope, aspect, and decide how you want to use that square

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
