Inches of Slope Decide Whether a New Sewer Line Lasts
Direct Answer: A sewer lateral needs a narrow band of fall, commonly around a quarter inch per foot. Too flat and solids settle. Too steep and liquid outruns solids, leaving buildup behind. Most people assume a sewer line fails because it was too flat. Water pools, solids settle, and years later the line backs up […]
Two Driveways, Same Asphalt, One Fails in Three Years
Direct Answer: The asphalt is rarely the problem. Driveways fail early because the subgrade under them was graded wrong, under-built on base rock, or never properly compacted, and because water had nowhere to go. I have walked two driveways in the same week that were paved with the same mix, by the same crew, in […]
Why Does Your Sonoma County Yard Flood Every Time It Rains Hard?
Direct Answer: Most Sonoma County yards flood because heavy clay soil drains slowly. Rain has nowhere to go, so it pools in low spots and runs toward the foundation instead of soaking in. You watch the rain come down, and within an hour the same corner of your yard turns into a pond. Two days […]
What the 2023 Pajaro Flood Taught Monterey County About Storm Readiness
Direct Answer: The Pajaro flood showed that low-lying Monterey County land fills faster than it drains. Storm readiness here means checking runoff paths, slopes, and access roads before the rain, not after. In March 2023, the levee along the Pajaro River gave way and the town of Pajaro went under. People were evacuated in the […]
The Reasons Site Plans Get Sent Back in Monterey County
Direct Answer: Most Monterey County site plans get sent back for drainage that does not reach a proper discharge point, earthwork quantities that quietly cross the 100 cubic yard grading permit threshold, and utility, access, or setback conflicts. You turned in a site plan, waited, and it came back with red marks and a list […]
How Late in the Year Can You Still Dig a Foundation in Santa Rosa?
Direct Answer: In most years, foundation excavation in Santa Rosa runs into late October or early November if the ground is still dry and permits are in hand. The first soaking storm usually ends it. Nobody brings up the calendar at the bid stage. You get a number, you get a start date, and everybody […]
French Drains: What a Properly Installed System Actually Requires
Direct Answer: A french drain needs a sloped trench, clean crushed rock, the right geotextile fabric, perforated pipe, and a working outlet. Skip any one of those and it clogs within a few seasons. Water pooling against a foundation is one of the most common calls I get, and the fix people ask for by […]
Culverts on Private Property: How Sizing and Placement Decisions Get Made
Direct Answer: Culvert size depends on the drainage area, slope, soil, and design storm above the crossing, not your neighbor’s pipe. Placement depends on invert elevation and protecting the outlet from scour. A homeowner in Monterey County wrote to us with a clear picture of their problem. An open drainage ditch ran across the front […]
Hauling Off 500 Yards of Dirt: Where the Soil From a Site Cut Ends Up
Direct Answer: Clean soil from a site cut usually goes to a quarry, an engineered fill site, or a nearby property that needs import material. Mixed soil with concrete or brush gets sorted and priced separately. A property owner getting ready to build in Carmel sent us a note that read like a short shopping […]
Trenching for Electrical Lines on a Residential Property: What the Job Involves
Direct Answer: Electrical trenching means digging a marked, code-depth trench, placing conduit, then backfilling and compacting it. In California, most residential branch circuit conduit sits at least 18 inches deep, with more required under driveways. Most people who call me about electrical trenching already know what they want. They want power out to a hot […]
