Bigger lots, longer drives
Henderson sits just north of Commerce City, and its larger industrial buildings share the same short list of water risks as any big single-story building: the roof, the dock edge, sprinkler lines, supply lines and storm runoff. This page doesn't describe any particular property.
Open sites often have more paved and graded land around the building, which means more runoff and longer drainage paths. They can also sit farther from the next building and from help. Plan to handle the first hours on your own, with a clear contact list and a first-hour checklist on the wall.
Weather hits open sites harder. Wind, snow and spring storms all work on roofs and doors, and a building at the end of a long access road can be hard to reach in a blizzard. Put each seasonal check on a calendar with a named owner and a completion date. Walking the building before winter and again before storm season catches most problems while they are cheap, and leaves a record of care if a claim ever comes up.
Planning prompts
- IfThe building sits on a large open lotThenAsk how runoff from the lot and nearby roads moves relative to the building.
- IfThe building is far from other facilitiesThenKeep protection supplies and a clear contact list on site.
- IfThe roof is large and low-slopeThenConfirm drain inspections and a ponding plan with the owner.
- IfThe site has a well or private water supplyThenLearn its shutoffs and who services it.
Keep on site

Common questions
How often should warehouse roof drains be checked?
At least twice a year, before spring storms and after the fall leaves drop, and again after any major hail or windstorm.
Why include Henderson?
It's a nearby community, and its large buildings face most of the same planning questions as Commerce City's.
