What Site Preparation in Woodland Actually Includes
Site preparation isn't a single task — it's the sequence of work that takes a parcel from current condition to build-ready. Scope changes based on starting condition (raw ag, cleared lot, post-demo lot) and the build that follows.
- Clearing and grubbing — vegetation removal, root extraction, surface debris cleanup; coordinated with land clearing scope if larger parcel
- Demolition coordination — removing existing structures, foundations, sub-slab utilities; tied to the City demo permit and 65% recycling ordinance
- Subgrade preparation — Yolo loam ripping below tillage pan depth on older ag parcels, moisture conditioning, and engineered compaction to project spec
- Pad construction — building pad to engineered grade and compaction; elevated pads in the Cache Creek floodplain require imported structural fill and elevation certificates
- Utility coordination and rough installation — PG&E electric and gas, City of Woodland water and sewer (or county septic on unincorporated parcels), storm drain, communications; trenching, conduit, and stub-outs for the building scope
- Drainage and grading — positive surface drainage, swales, area drains, and connection to storm system; Yolo loam holds water so drainage discipline matters
- Erosion and sediment control — NPDES Phase II coverage on projects disturbing 1+ acre; SWPPP, BMP installation (silt fence, fiber rolls, stabilized construction entrances)
- Final rough grade and turn-over — site at engineered grade, utilities stubbed, erosion control in place, ready for foundation work
Spring Lake New Construction and ADU Prep
Two of the most common site-prep scopes in Woodland right now: production homebuilder pad work in the Spring Lake Specific Plan area, and ADU prep on older infill lots. Each has different scope drivers but they share the Yolo loam subgrade.
- Spring Lake Specific Plan (adopted Dec 18, 2001, ~4,000+ units at buildout): Taylor Morrison, Meritage, and other production builders continuing pad-grading and lot prep into 2026; standardized subdivision specs, geotech-driven compaction, coordinated utility installation
- ADU pad prep on existing residential lots (Beamer Park, East Street, Streng Bros enclave, downtown-adjacent): detached ADU footprint typically 600–1,200 sq ft, sited on deep rear yards; coordination with primary residence grade, drainage, and utility laterals
- Setback and yard access: ADU work often runs through side yards 6–8 ft wide — equipment selection (mini excavator, compact track loader) and material staging plans are part of the site-prep estimate
- Primary residence protection: existing foundations, landscaping, and hardscape need protection during ADU site work; we plan haul routes and equipment paths to avoid collateral damage
- Utility laterals: ADU water, sewer, electric, and gas connections coordinated with primary residence; sub-meter or independent meter decisions affect trench routing
- 65% C&D recycling on the ADU permit applies; refundable 3% deposit at permit issuance
Ag-to-Residential Conversion Site Prep
Older orchard, row-crop, and pasture parcels on Woodland's east and south edges are being converted to residential — either individual estate-lot builds or smaller infill subdivisions. The legacy ag infrastructure dictates the site-prep scope.
- Orchard root ball extraction — full removal to 3–5 ft depth; partial cuts leave decomposition voids that fail under foundations
- Irrigation pipe decommissioning — buried PVC laterals, concrete standpipes, tailwater pumps and sumps need to come out cleanly
- Abandoned well destruction — under Yolo County Environmental Health protocols; documentation required for closure
- Wind row removal — eucalyptus, cypress, oleander wind rows are bigger jobs than they look; large root systems require excavator extraction
- Tillage pan ripping — 12–18 in deep compacted layer from decades of disking must be ripped before pad subgrade can be properly compacted
- Old farm outbuilding teardown — barns, sheds, chicken coops, pump houses; pre-1980 structures get asbestos and lead testing first
- Soil profile assessment — most ag ground in Woodland sits on Yolo loam or closely related series; geotech may recommend conditioning, lime treatment, or import for specific structural pads
NPDES Erosion Control, Floodplain, and 65% Recycling Integration
Most multi-lot or larger site-prep projects in Woodland trigger state stormwater permit obligations, floodplain review if applicable, and the City's recycling ordinance. We integrate these from day one rather than scrambling at inspection.
- NPDES Phase II Construction General Permit: required for projects disturbing 1+ acre of soil; State Water Resources Control Board coverage with SWPPP prepared by QSD, BMP installation by QSP-managed crew
- Erosion control BMPs: silt fence, fiber rolls, gravel construction entrances, inlet protection on storm drains, stabilized stockpiles; updated as construction phases change
- Yolo-Solano Air Quality Management District: dust control on bulk earthwork; watering active zones, haul-route management, wind-event protocols
- Cache Creek floodplain projects: additional review through cityofwoodland.gov flood zone information; elevation certificates at pre-construction, during construction, and final
- City 65% C&D recycling ordinance: applies to permitted projects generating C&D debris; refundable 3% deposit at permit issuance (cap $15K, floor $500), released after recycling documentation is approved
- Source-separated disposal at Yolo County Central Landfill (44090 County Road 28H): clean wood, metal, concrete pulled as separate weight tickets to satisfy the 65% recycling requirement cleanly
- USA North 811 utility location: required minimum 2 working days before any subsurface work; we pull tickets and white-line where called for
Frequently asked questions
What does full site prep cost in Woodland?
A typical single-family or ADU site prep on an existing residential lot runs $8,000–$25,000 depending on parcel condition, drainage scope, and utility extension distance. Ag-to-residential conversion adds $5,000–$30,000+ on top for orchard root removal, irrigation decommissioning, and tillage pan ripping. Cache Creek floodplain elevated-pad work adds $15,000–$40,000+ depending on the BFE delta and required import fill volume. Spring Lake subdivision pad work is bid per-lot under the developer's master specs and runs separately from individual residential pricing.
Do I need a stormwater permit for site prep in Woodland?
If your project disturbs 1 acre or more of soil — including any combined-acreage project under one plan — you need coverage under California's NPDES Phase II Construction General Permit. That requires a SWPPP (Stormwater Pollution Prevention Plan) prepared by a Qualified SWPPP Developer (QSD), BMP installation, and inspections managed by a Qualified SWPPP Practitioner (QSP). Smaller projects under 1 acre are subject to the City's local erosion and sediment control standards rather than state coverage. We handle the SWPPP coordination and BMP work as part of site-prep scope on projects that need it.
How does the Spring Lake builder process work?
The Spring Lake Specific Plan was adopted by the City of Woodland on Dec 18, 2001 — 4,000+ housing units at buildout. Production builders like Taylor Morrison and Meritage have continuing pad-grading and lot-prep work into 2026. Builder-direct site prep runs under the developer's master specs (geotech-driven compaction, standardized utility installation, coordinated drainage). Individual lot prep for custom builds within the plan area follows the same engineering standards but is bid lot-by-lot. We work both — production builder scopes and individual custom-build lot prep.
What happens to the C&D recycling deposit?
At demo or grading permit issuance, the City of Woodland requires a refundable C&D deposit equal to 3% of total project value, capped at $15,000 and with a $500 minimum. After the project, we submit weight tickets from Yolo County Central Landfill documenting that at least 65% of the C&D debris was recycled — typically by source-separating concrete, clean wood, metal, and roofing on-site and pulling material-specific weight tickets at the recycling rate. Once the City reviews and approves the documentation, the deposit is refunded. We handle the documentation and submission as part of our site-prep and demo scope.
How long does site prep take in Woodland?
Standard residential or ADU site prep on a cleared lot runs 1–2 weeks once permits are in hand. Ag-to-residential conversion with root extraction, irrigation removal, and tillage pan ripping adds another 1–3 weeks depending on parcel size. Floodplain elevated pads with significant import fill add 1–2 weeks for haul cycles and compaction sequencing. Permit timelines run on top of execution — City of Woodland and Yolo County permits typically issue in 2–6 weeks for standard scopes; historic district HPC review on contributing buildings can add months on the front end.
