Stormwater containment design ballpark fee

[IsaacStructural]

I've got a project with a civil component and I'm looking for a general guideline concerning the price. The project is a city parking lot, 100'x125'. The scope of work is a boundary and topo survey and stormwater design, with a couple curb cuts.

Although I don't do civil work anymore, this doesn't seem like an especially large or demanding project. The civil engineer we typically work with gave us an estimate that the project would take 80hrs, not including the survey/topo, which would be performed by others. Is this a reasonable time estimate?

Our client indicated they had received other proposals that were substantially cheaper, though I didn't ask for the exact number.

Anyone care to share a general range for this work? I understand local factors come into play, but I'm looking for some guidance.

Thanks.

I may have used the wrong word in the title of this thread, I don't know that the lot needs an actual containment structure, it just needs conventional drainage design, which may or may not involve storing/containing water.

Seems reasonable, if that 80 hours includes the admin work required to put the report together, review the design, revise the design once, probably a meeting or two?

That seems reasonable if there is no permitting and no design changes. I've never done a project without both.

Depends drastically on the municipality, the nature of the regulations, and the complexity of the project. I'm not familiar with IL. You mention curb cuts, does that mean you need a DOT permit? Traffic study? Rezoning? You looking for the whole civil drawing package, or just the stormwater report to accompany someone else's civil package?

Since this is the stormwater forum, I presume the latter. I'd do the "site hydrology study" or "stormwater management report" or whatever folks call it where you're at, for between $3000 and $8000, depending on your location and your regs. Much more likely at the low end if it's just a parking lot and the regs are simple. That would include one meeting with city officials and a site visit. The $8000 fee would be more for a multi phase 50+ acre urban redevelopment with multiple green BMPs in a convoluted municipality.

The ballpark fee estimate for civil plan sets I've seen thrown around here quite a bit is $1000/sheet, plus/minus.
