Seasonal Defensible Space Checklist: Spring & Fall

Defensible space isn’t a one-time project — it’s maintenance, twice a year, or it drifts back to where it started. This checklist splits the work by season, since spring and fall each address different risks.

For the reasoning behind why each zone matters, see the defensible space guide. This page is the shorter, do-this-now version.

Spring checklist (as snow clears through early summer)

Spring is about undoing winter damage and getting ahead of the growing season before things green up and get harder to distinguish from healthy growth.

Zone 1 (0–5 ft):

• Clear winter debris — broken branches, needles, and anything blown against the house
• Check gutters and roof valleys for accumulated needles and leaves
• Inspect under decks and crawl spaces for debris that collected over winter
• Check that firewood and mulch are still clear of this zone (it’s easy for a stack to creep closer over a season)

Zone 2 & 3 (5–100 ft):

• Walk the property for winter-killed or storm-damaged trees and branches — dead wood from winter is drier and more flammable than live fuel
• Check crown spacing on any trees that grew or were planted since your last review
• Cut back any ladder fuels that established themselves over the previous season

Planning:

• If you’re budgeting for larger tree removal or thinning this year, get quotes early — spring is when contractor calendars fill fastest, and it’s also the season tied to most grant application cycles
• Take dated before-photos if you’re planning to apply for a rebate or grant

Fall checklist (after growing season, before snow)

Fall is about cleanup before things go dormant and dry, and before snow load makes damaged trees a hazard.

Zone 1 (0–5 ft):

• Rake and remove fallen leaves and needles — this is the single most-skipped fall task and one of the highest-impact ones
• Clean gutters again — fall leaf-drop refills them even if you did this in spring
• Cut back any perennials or ornamental grasses that have dried out for the season

Zone 2 & 3 (5–100 ft):

• Chip or haul away any slash left over from summer thinning work — piled dead wood sitting through fire season into fall is a fuel load, not a solved problem
• Do a final mow of tall grass before it cures (dries and hardens) for winter
• Note any trees that look stressed or dying for spring removal — fall is a good time to spot them since deciduous cover has dropped and problems are more visible

Wrap-up:

• Confirm any grant or rebate paperwork is submitted before program deadlines close — some programs cut off well before the calendar year ends
• If this year’s assessment turned up bigger jobs (tree removal, major thinning) for next season, get on a contractor’s schedule early rather than waiting until spring demand picks up

A note on chipping and debris disposal

Slash and debris removal is often the part of this work homeowners underestimate — cutting vegetation is only half the job if you then have piles of cut material sitting near the house through fire season. Some areas host seasonal community chipping events; check with your local fire protection district for current dates, since these aren’t standardized across Routt County and change year to year.
