Site needing preparation before construction
The plans exist, the builder is picked, and between you and groundbreaking sits the dirt work: clearing the envelope, cutting access, shaping the pad, trenching prep, and drainage. Sequenced as one scope, it's weeks; discovered piecemeal mid-build, it's the delay everyone blames on the weather.
What it looks like
- A build date with uncleared, ungraded ground
- A builder asking when the pad will be ready
- Septic evaluation not yet started (the long pole in this county)
What usually causes it
Common causes in this valley — which of these applies to your property can only be settled by looking at it.
- A permitted build with no site work scheduled yet
- A design assuming a flat pad that does not exist
- Access, utilities, and septic routes not yet cleared
When this needs a professional evaluation
Pad elevation, compaction, and foundation-bearing requirements come from your engineer and building plans. Site preparation executes that design — it does not originate it.
The work that fixes it
Worth knowing in this county
- Stormwater discharge from construction activity requires MPDES permit coverage from Montana DEQ under General Permit MTR100000, obtained by filing a Notice of Intent and a Stormwater Pollution Prevention Plan. Confirm the current disturbance threshold and timing with DEQ while the design is still on paper — it is a schedule item, not a formality.
- Septic groundwater monitoring can span to the following spring — start the evaluation before anything else on unserved parcels
Before you reach out
- Share the site plan and any septic design — dirt work follows drawings
- Confirm jurisdiction (city vs. county) — it decides whose rules apply
Common questions
When should site prep happen relative to the build?
Finished the season BEFORE breaking ground, ideally — a fall-prepped pad meets spring builder schedules instead of chasing them.
