Why Davenport prices look the way they do
Labor is 56% of the midpoint bill here, against 52% nationally. The mix of trades behind this job is construction laborers (50%), operating engineers and other construction equipment operators (30%), pipelayers (20%). We weight each trade's local median wage by that share and compare it with the national median. In Davenport the blended ratio comes out at 1.12.
On the materials line, the BEA goods price index for the Davenport metro is 94.2 (US = 100). The midpoint materials bill for 60 linear ft comes to $610, compared with $650 at national prices. Permit and inspection fees are scaled by the broader index (89.1) and land at $0 to $0.
Data note: 20% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Davenport. The wage table below marks each row.
When to schedule French drain in Davenport
We use NOAA's 1991-2020 climate normals for Davenport (5 miles from the city center). These are 30-year monthly averages, not forecasts.
April through October is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in Davenport (7 of 12 months). January, February, March, November and December have an average overnight low at or below freezing (32°F).
In January, February, March, November and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 136 days a year with a low at or below 32°F at this station.
Davenport gets about 36 inches of precipitation in a normal year. The wettest months are May, June and July (4.8 inches in May). Inside the workable window, September and October are the driest, at 3.5 and 2.7 inches. The station averages about 13 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.

Davenport: what basic, standard and premium work costs
Three bands are cut from the same cited range and localized for Davenport wages and prices. They overlap on purpose: a good standard job and a modest premium job can cost the same. The grid below prices the same bands at 3 common sizes.
Basic
$620 to $1,250
Shallow yard drain, easy digging
Standard
$1,100 to $1,700
Standard drain with fabric, gravel and a pop-up outlet
Premium
$1,550 to $2,150
Deep or long drain, hard soil, dry well or sump discharge
| Size | Basic | Standard | Premium |
|---|---|---|---|
| short run (30 linear ft) | $310 – $620 | $540 – $850 | $780 – $1,100 |
| side yard (60 linear ft) | $620 – $1,250 | $1,100 – $1,700 | $1,550 – $2,150 |
| long run (120 linear ft) | $1,250 – $2,500 | $2,150 – $3,400 | $3,100 – $4,350 |
Local wages behind the labor line
Wages are the part of this estimate that changes most from town to town. 3 trades carry the job here, and each is compared with its US median. The weighted result for Davenport is 1.12 times the national level.
Construction laborers (47-2061), 50% of the weighting: a median of $26.14 an hour, 15% above the US median of $22.66. The middle half of them earn between $21.74 and $33.98 an hour. About 1,320 work in the metro. That is 73.2 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
For operating engineers and other construction equipment operators (47-2073, weighted 30%) the local median is $31.18 an hour, which is 8% above the national $28.78. The middle half of them earn between $25.71 and $40.96 an hour. BLS counts 570 of them working in the area, 31.6 for every 10,000 jobs (US: 30.7), so the local bench is about average.
Pipelayers (47-2151) carry 20% of the labor weighting. BLS does not publish this trade for the Davenport metro, so we used the Iowa statewide median: $25.96 an hour against $23.56 for the US. The middle half of them earn between $24.13 and $27.79 an hour.
Quotes come from real crews, not medians. If the construction laborers on your job are paid at the 75th percentile ($33.98 an hour) instead of the median, the labor line grows by about $120. At the 25th percentile ($21.74) it shrinks by about $70. The total moves by 8.7% or 4.9%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 180,450 jobs in the Davenport-Moline-Rock Island area. That makes it the 128th largest of the 300 metros we cover, with 0.12% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Construction laborers (47-2061) | 50% | $21.74 | $26.14 | $33.98 | $22.66 | 1.15 | metro |
| Operating engineers and other construction equipment operators (47-2073) | 30% | $25.71 | $31.18 | $40.96 | $28.78 | 1.08 | metro |
| Pipelayers (47-2151) | 20% | $24.13 | $25.96 | $27.79 | $23.56 | 1.10 | state |

Where the water goes

Depth and soil
Rocky or clay soil and long trenches raise excavation time.
