One printable sheet: materials with sourcing, the anchoring decision, the back-to-gate build sequence, and the site-specific fixes. Built so each bay is a finished section you can stop on.

The eleven line posts ride on OZ-Post T4-850 driven anchors — a 34 in hot-dip galvanized spike with a sleeve that holds the post above grade. That's the "single metal rod, replaceable, no concrete" idea done right: unbolt or re-drive to replace, and nothing wood ever touches wet soil. Your reference fence uses this exact detail — cedar boards on a post held above grade by a driven galvanized anchor, bolt through the post, gap underneath.
A bare driven anchor can't hold a swinging gate — the hinge post racks loose. The three heavy posts (two gate, one straining) go on a standoff base set in a small fast-set footing. Still replaceable (unbolt), but rigid. Your existing standoff-on-pier setup is exactly this — reuse those piers if they're sound.
Order runs back → front: set the 4×6 straining post first (it's the datum every string line references), then the back-section line post and both gate posts, then repeat the bay module down the 58 ft main run. Each finished bay is a section you can stop on.
| # | Post | Type | Base | To next |
|---|---|---|---|---|
| 1 | Back straining | 4×6 | standoff + footing | 5 ft |
| 2 | Back line | 4×4 | driven anchor | 5 ft → gate |
| 3 | Gate hinge | 4×6 | standoff + footing | gate ~3.5 ft |
| 4 | Gate latch | 4×6 | standoff + footing | 5.8 ft |
| 5–14 | Main-run line ×10 | 4×4 | driven anchor | 5.8 ft O.C. to end |
| Pain point | Why it matters | Fix |
|---|---|---|
| Running bamboo | Rhizomes already push through pickets and shoot up at the base; will bow/break a new fence. | 60-mil HDPE barrier trenched 24–30 in, edge 2 in proud, deflecting rhizomes down. Non-negotiable if the bamboo stays. |
| Posts rotting at grade | Wet, mossy, shaded channel — concrete-set posts trap water on end-grain. | Driven anchors hold every post above grade + 3 in picket clearance + caps. Nothing structural touches soil. |
| Slab crowds the base | Only a 4–6 in soil strip between walkway and fence; some posts land on concrete. | Drive anchors in the bed just inside the line; core the slab or shift the post where it lands on concrete. Confirm soil before ordering. |
| Foundation vent | Blocking the crawlspace vent causes moisture problems under the house. | Keep it clear; hardware cloth over it, never soil or gravel. |
| Narrow access | Tight passage — 12 ft rails and a jackhammer are awkward to swing. | Pre-cut rails outside the passage; use the manual driver where a jackhammer won't fit; stage material at both ends. |
| Gate sag | Long lever arm on a cedar gate in a damp spot — the likeliest failure. | 4×6 hinge post on footing, wood brace in compression + cable/turnbuckle in tension, heavy hinges. Clear the clematis first. |
| Fastener corrosion | Bright steel against cedar in this microclimate rusts and streaks in a season. | Hot-dip galvanized / coated fasteners and HDG anchors throughout — already in the BOM. |
