What is behind the Boise number

Labor is 47% of the midpoint bill here, against 46% nationally. The mix of trades behind this job is brickmasons and blockmasons (50%), construction laborers (30%), operating engineers and other construction equipment operators (20%). We weight each trade's local median wage by that share and compare it with the national median. In Boise the blended ratio comes out at 1.01.

Materials are scaled with BEA's regional price parity for goods. Boise is at 96.2 against 100 for the US, so a materials line of $5,300 nationally becomes $5,100 here (midpoint, 200 sq ft of wall face). Permits follow the all-items index of 98.4: $50 to $440.

Boise weather and the retaining wall calendar

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Boise Air Terminal (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.

For digging, grading and setting material in the ground, the comfortable months in Boise are March through June and September through October: 6 of 12. Outside them, January, February, November and December have an average overnight low at or below freezing (32°F), and July and August have an average daytime high of 90°F or more.

In January, February, 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 108 days a year with a low at or below 32°F at this station.

Boise gets about 12 inches of precipitation in a normal year, including roughly 18 inches of snow. The wettest months are January, May and December (1.5 inches in December). Inside the workable window, June and September are the driest, at 0.8 and 0.4 inches. The station averages about 55 days a year at 90°F or above.

We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.

What local crews earn in Boise

The labor line is built from BLS wage data, one trade at a time. This job draws on 3 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Boise the blend is 1.01.

For brickmasons and blockmasons (47-2021, weighted 50%) the local median is $30.06 an hour, which is in line with the national $29.87. The middle half of them earn between $28.30 and $37.48 an hour. BLS counts 150 of them working in the area, 3.8 for every 10,000 jobs (US: 3.4), so the local bench is about average.

For construction laborers (47-2061, weighted 30%) the local median is $22.84 an hour, which is in line with the national $22.66. The middle half of them earn between $19.98 and $25.18 an hour. BLS counts 4,700 of them working in the area, 120.0 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.

Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $29.29 an hour, in line with the US median of $28.78. The middle half of them earn between $25.58 and $31.56 an hour. About 1,730 work in the metro. That is 44.2 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.

A quick sensitivity check: moving the lead trade (brickmasons and blockmasons) from the median to the 75th percentile wage adds about $580 to the midpoint estimate; the 25th percentile takes off about $140. That is a swing of roughly 1.4% to 5.8% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Boise City has 391,790 jobs in total (BLS, May 2025), ranking 67th by size among the 300 metros on this site.
