Sounds like you are in Missouri since you mentioned Missouri maps. Have you talked with MoDOT? I'm in Illinois and IDOT is on their second round of LiDAR mapping the entire state, see https://clearinghouse.isgs.illinois.edu/data/elevation/illinois-height-modernization-ilhmp. I thought this...
I know the code is a minimum operating pressure of 20psi at service connections, but what are the restrictions against low pressure along the course of the water main? In our case we have a private 4" main that is functioning more like a transmission main feeding a camp with demand of 30gpm...
In my location, we typically use 4" of topsoil stripping and stockpiling as a pay item in SY in addition to earth excavation and embankment in CY. Essentially we strip off what we place back, so it is a wash and don't detail it in the cross sections. On larger projects with known areas of...
How about a nice, but used instrument? In the past, I purchased a used Sokkia 2100 and data collector for $2500 USD. I would think you could find a nice used Lecia unit, if that's the instrument you are used to running.
Not New York's, but here is Illinois.
Commonly Used Quantities of Sewage Flows From Miscellaneous Type Facilities

This sounds correct, provided this is just for truck parking. I had facility that had forklift loading of flatbed trailers in the yard, that had additional slope constraints on the forklift operations.
I'm late in responding, but in Illinois the State Fire Marshall's Office also has a defined setback from the public ROW to the gas pumps. I assume the client has defined the basic of the project for number of pumps, ...
I'm assuming that this is an existing paved gore? If so, I would say yes. I had to rework some interstate ramp gores earlier on in my career that were design improperly with too great of a drop-off / over-break between the high-side of the on-ramp's super elevation and the gore.
On another...
I suspect they'll have more consternation with the previous fill than the request for a parking area. Regardless, it sounds like it could be permissible provided all of the vehicles are operable. I like to use our DNR's quick guide as a first pass review and then drill down deeper if needed...
Are you trying to control velocities in the pipe? I have stair stepped the storm sewer, using drop manholes to avoid a steep, straight-line grade. I would offer that the flow impacting the opposite side of the manhole and free fall dropping to the outflow invert is also a decent energy dissipater.
Get on the State DOT website and look up recently award contracts and their bid unit prices. Pay attention to the overall dollar value of the contract and amount of asphalt. Open miles of interstate paving will cost less per ton than in town paving.
Not sure if this is the same application you are inquiring about, but I had a municipal client with a 0.3 MGD two cell lagoon that replaced their coarse bubble static aerators with micro bubble diffusion (MBD) aerators. The reduction was from 101 static tubes to 8 floating MBD aerators. The...
This thesis by TW Erkert has a great discussion on it, https://ir.library.oregonstate.edu/downloads/bk128g99t. He discussed the Society of Automotive Engineers' "Sum of Squares of Wheelbases" and other agencies' empirical methods. My temptation would be to scan and scale the WB50's template in...
So here in Illinois, the one exception for requiring a PLS is topo by an PE supporting their own engineering project - no standalone topo work. I'd say the drone service would be a violation here, regardless of a disclaimer if topography or property lines were shown...
I would show both alignments on a survey control sheet as you mention and reference just the design alignment on the paving sheets for clarity (I assume you'll be grey-scaling the existing roadway on the paving sheets).
I had not heard that before. A quick review of some sources of the templates shows them starting the turn with the steering axle straight ahead (see http://image.slideserve.com/259312/aashto-turning-templates-l.jpg).
Does anyone know where I could find the duration for the peak flow estimates generated by USGS regression techniques? The equations use a rainfall intensity, I based on a 24-hour rainfall with a 2 year recurrence interval. Curious if the other peak flow events, such as Q(10), Q(25), ..., are...
