Most Poway owners already have a yearly rhythm. Brush gets cut in spring. Gutters get cleared before the first storm. Slopes get a look after big rain.
The structure fits into the same rhythm. You don’t need a new set of chores. You need to look at a few extra things while you’re already outside.
This is a simple routine built around Poway’s two real seasons. Use it as a checklist. Change it to fit your lot.
Why two seasons, not four
Poway’s dry season is long. The City’s vegetation FAQ says the dry season typically runs from May through November. That is also when weed abatement inspections happen.
The wet season is short. Most rain falls in a few months. Some years bring a handful of big storms. Some years bring almost nothing.
That swing matters for structures. Clay soils shrink when dry and swell when wet. Fill slopes and pads get tested by runoff. Granitic ground drains well in some spots and sheds water hard in others. The California Geological Survey’s map pamphlet describes both kinds of ground in this part of the county.
So the routine has two halves. One for dry. One for wet.
Spring: clearing brush, checking the ground under it
Brush clearing is the one time each year you see the ground near your house clearly. Use it.
The City’s FAQ says crews should mow or weed-whip and leave roots in place. Spraying is not accepted. Dead shrubs and trees must be removed. Follow those rules. Then, while the ground is open:
- Walk the base of every wall. Look for gaps between the soil and the slab edge.
- Look at slope faces near the house. Note any fresh cracks in the soil or bulges.
- Check block and boulder walls for new lean, open joints or cracks.
- Look at weep holes in retaining walls. Make sure they’re not packed with debris.
- Take dated photos from the same spots you used last year.
Our post on defensible space near the foundation covers how clearing and structure overlap.
Early summer: the shrink starts
As soil dries, clay shrinks. Gaps open along slab edges. Doors may start to rub on one side of the house.
Things to do:
- Watch doors and windows that stuck last year. Note when they start sticking again.
- Check irrigation. A broken line in summer can soak one corner for weeks.
- Keep drip zones and lawn sprinklers away from the foundation edge.
- Measure any cracks you are tracking. Use a crack card or a ruler. Write the date.
A steady pattern from year to year is often normal seasonal movement. A crack that keeps growing is not.
Late summer and fall: hot, dry, and Santa Ana winds
This is the heart of fire season. It’s also the driest the soil gets.
Structural checks to add:
- Look at decks and stairs on slopes. Check posts, footings and connections.
- Look at outbuildings: barns, sheds, workshops, guest units. Check footings and slab edges.
- Look at wood near the ground for rot, especially where sprinklers hit.
- Check crawl-space vents. Make sure screens are intact.
If you plan any repair work before winter, this is when to start the conversation. Engineering and permits take time.
Before the first storm
Do this in late October or November, before rain arrives.
- Clean gutters and downspouts.
- Make sure every downspout discharges away from the house.
- Clear area drains, brow ditches and terrace drains on slopes.
- Check that the soil next to the house slopes away. The residential code asks for a fall away from the foundation, typically six inches in the first ten feet where the lot allows.
- Clear inlets and culverts on long driveways.
The County’s private drainage flyer is clear on one point. Drainage on private property is the owner’s job. That includes swales, pipes and the ground itself.
During and after big rain
Walk the property during a steady rain if it’s safe. Watch where water goes. Then walk again a day or two after.
- Look for ponding against the house or garage.
- Look for water running over the top of a retaining wall instead of through its drains.
- Look for soil washing out at the toe of a slope or below a downspout.
- Check the crawl space for standing water.
- Note any new cracks inside the house.
Our after-rain slope walk goes step by step.
Winter into spring: the swell
Wet clay swells. Things that opened in summer may close. Doors that rubbed may swing free. This is normal for many Poway homes on clay.
What you want to know is whether the cycle is stable. Compare this winter’s notes and photos with last winter’s. Same cracks, same widths? Probably seasonal. New cracks, wider cracks, or a door that never recovers? Worth a closer look.
Large lots need a route, not a glance
Many Poway properties are big. An acre or more. A long driveway. A barn, an arena, a pool on a terrace, a guest house down the hill. It’s easy to check the main house and forget the rest.
Make a fixed route. Start at the street. Walk the driveway and its culverts. Then the main house, all four sides. Then each outbuilding. Then the slopes, top and bottom. Finish at the lowest point of the lot, where water ends up.
Walk the same route each season. Take photos at the same stops. Over a few years, the route becomes your best record of how the property behaves. Small changes stand out because you’re always looking from the same place.
Keep one simple record
All of this works better on paper. Keep a short log:
- Date.
- What you checked.
- What you saw.
- A photo, taken from the same spot each time.
A year of notes gives anyone who evaluates the house a head start. See our post on monitoring for more on tracking cracks.
When to call
Call when the pattern changes. A wall that leans more. A slope that shows new cracks. A crack that keeps widening through both seasons. Water you can’t get away from the house.
We can walk the property, look at the foundation, slopes and walls, and explain what we see. Our foundation inspection page explains what a visit covers. For slopes, see hillside foundation repair.
