Stagecoach Road Ranch


Foundational Site Assessment


Location: San Luis Obispo, CA

Land & Climate Characteristics: A primary valley oriented mostly on a northwest x southeast axis (which a highway follows on the east side of the valley) and traversed along its bottom by a county road. Temperatures with typical highs between 60-85โ„‰ and lows that only very rarely drop below freezing, with an average of 450 chilling hours (<45โ„‰) per year.

The center of the ranch, Highway 101 visible in the upper right.

Average rainfall of approximately 22 inches per year, with approximately 400 million gallons of water landing on the property per average rain year. Abundant, perennial water is available from two springs located on the east side of the property, which is used to supply current ranch needs. Gravel-, sand- and clay-loam soils with moderate to high fragility, generally low to moderate permeability, high runoff potential, and high erosion hazard.

Foundational Site Assessment Key Takeaways


The following issues were identified during the FSA which will pose significant ongoing challenges to the landowners in meeting their goals unless rectified:

  • Water
    • Unmitigated point-sources of high-volume, high-energy run-on from the various highway drainage systems onto the western half of the ranch, which have contributed significantly to headcutting, incising of drainages, overall dehydration of lower pasture zones and loss of topsoil.
  • Access
    • Difficult/cumbersome/dangerous access across highway and in steeper portions of property on both east and west sides.
    • Public vehicle access through the heart of the property and Ranch HQ via the county road has led to trespassing on the property and increased security risks.
  • Shelter
    • Existing residential locations assessed for their energy efficiency and physical security.
  • Living Systems
    • Overgrazed and degraded pastures that generate a large amount of surface run-off contributing to soil erosion down watershed. Pastures have very low organic matter content, low moisture retention, low litter and perennial cover, and very low biological activity, and their current productive capacity is a small fraction of what they can be.
      • Lack of vegetative cover is significantly contributing to the runoff issues noted above, which guarantees decreasing soil fertility with each passing year.  Living root mass is the most effective means of infiltrating water into the soil where it can be productively used by plant roots and soil biota.
      • Soil compaction due to loss of soil structure, and thus decreasing water infiltration and water storage capacity. The pore spaces that are created in a healthy, living soil from plant roots, the exudates they produce, and the soil biology they help to protect and sustain are diminished or gone entirely in some places.
  • Energy
    • Huge opportunities for resilient and grid-independent energy production, including solar PV and solar thermal, as well as biomass for clean wood burning devices for cooking, water heating, space and people heating and more.
  • Economy
    • Currently minimal income generation from the ranch.

Mainframe Design


Client Vision And Goals: The landownerโ€™s communicated a desire to live together on this family property and regenerate degraded portions of the landscape, with the following major goals:

  • To live together as a multi-generational family unit while feeling safe, secure and serene on the land.
  • Improve ability to monitor, manage and maintain the more distant portions of the property.
  • Rehabilitate the health of the soils.
  • Provide an educational space for schools and organizations to engage with nature. 
  • Inspire the community with art.
  • Improve the wildlife habitat and access throughout the property.
  • Generate multiple income streams from the land and integrated enterprise so that the ranch can remain in the family and be preserved as a community resource for generations to come.
Property center, with main residential family compound and future housing sites, barn and workshop, tenant rental sites, and keyline swale system throughout the main pasture block.

Design Elements


  • Water
    • Passive water harvesting systems above and throughout lower pasture zones west of the highway to slow, spread, and ultimately infiltrate into the soils of the pastures an estimated 20-45 million gallons of rainwater that is currently running off of and eroding the compacted soils during every average rain year.
    • Energy dissipation structures at all culvert outlets to de-energize discharge flows, reducing and ideally halting their ability to contribute to further downstream incising of drainage paths. 
  • Access
    • Assume responsibility for county road maintenance and add gate to close off to non-resident vehicle traffic . Limiting vehicle traffic to that of property residents, county personnel, and utility maintenance staff should significantly reduce the amount of trespassing on the west side of the property that occurs from the county road. 
  • Shelter
    • Additional residence locations identified and ranked relative to one another for solar access, physical security, acoustic and visual privacy while still having a good view over large portions of the ranch center, and cost/complexity of building in each location. Increasing the number of people who are living on the property has the potential to help with almost all of the development and maintenance logistics, discourage the frequency of trespassers, and generally create more of a community feel on the property. 
  • Living Systems
    • Broadacre silvopasture system (the integration of tree crops and animal grazing systems) designed around mainframe passive water harvesting features.
    • Multi-yield fuelwood and livestock fodder production using coppicing and pollarding to maintain silvopasture blocks. 
    • Intensively-managed ruminant livestock, pasture rejuvenation using the recommended passive water harvesting system, and silvopasture plantings in pasture areas.
    • Privacy screens/windbreaks along boundary and internal fences (especially along the county road and highway) to enhance visual and acoustic privacy with CA native and food producing varietals in a “fedge” (food producing hedge).
  • Energy
    • Wood-fired cooking and space and water heating systems in current and future residences and shops heated with small-diameter coppiced stick fuels produced from silvopasture systems.
  • Economy
    • Identification of most desirable “glamping” zones for Hip-Camp and/or tiny home AirBnb units based on solar access, acoustic and visual privacy, natural surroundings, physical security and overall ambience.
    • Additional enterprise partnership opportunities with local apiaries and regenerative graziers.
