You say "If I keep the grade the way it is and send the runoff to the arterial drainage system, it'll back up in a larger storm and flood the area." Does that happen now?
If it does, then you aren't worsening the situation and the municipality can't really make you pay to clean up a...
"Quick" and dirty method....
1) Draw your arc using Start, End and Centre ensuring that you "overshoot" the arc length required.
2) Check the properties of the arc to determine the actual length drawn.
3) Draw a line from the end of the arc that is long enough to make the...
"Best location for who?" is the question that gets asked around here.
Traditionally here we use a 20.12m (66') R.O.W. which is now becoming a 20.0m R.O.W. as various Municipalities switch their old design standards to metric. Residential roads are generally have an 8.5m clear width...
The problem most likely lies in the system variable DIMASSOC. If its set to 0 or 1, it will show the paperspace units. If it is set to 2 you will get associative dimensions that automatically scale properly to show the modelspace distances.
So, the fix is to always ensure that DIMASSOC is set...
If the polyline runs from right to left, that means that either:
1) The polyline was drawn right to left
2) The intial segment selected to turn the segments and arcs into a polyline using the join command was drawn right to left.
One method of reversing the polyline is as follows:
1) Draw a...
We hashed this around in our office when I attempted to put together a drafting standard. You have basically 2 choices:
1) Create text styles than are based on whatever scale the drawing will be printed at. (For example, any of our text styles that are to be used for a 1:500 scale drawing end...
Hello,
We've been approached to look at the stormwater and sanitary sewer design for a truck stop/service centre. I'm looking for any standards or "rules of thumb" for sanitary flows from truck stops and their associated restaurants.
We're already looking at possibly getting some...
Reading johnd43's response, it looks like I wasn't as clear as I could have been in my concluding statements...
Required Pipe & Slope to handle flow = 10" @ 0.03%
Required Pipe & Slope to ensure self cleaning = 10" @ 0.30%
So, yes you were correct in thinking the pipe was oversized...
The way we handle this in our office is by taking advantage of the fact you can have multiple paper space layouts and AutoCad's Design Center.
We have 1 Drawing that contains all our standard blocks, layers, text styles, dim styles, etc located in the model space. Then we have a paper space...
In order to answer your question the following information is required:
Population per residential unit
Average daily flow per capita
Average daily flow rate for retail/commercial space
That said, using our local standards or 2.5 cap/unit, 341 l/cap/day (75 igal/cap/d) for residential and...
Hmm.. tough one...
Your best arguement would probably be flooding damage resulting from only sizing the sewers for a 5 Year storm.
Next would be that either the upper tier or other higher level authority requires the higher design storm.
Third best is probably something along the lines of...
In order...
A = A variable for which the only possiblity is "A"
.5 = length of first line
-.2 = length of gap before text
S = Text scale
R = Text rotation
X = text offset relative along the line
Y = text offset above or below the line
-.25 = gap after the "gap before text"...
This issue has come up several times in our office, mainly because of the fact that on some projects, my bosses are also the developers in addition to being the engineers. The arguements here go like this:
1) Barrier curb does a better job of keeping vehicles on the street but requires curb...
1) 1.5m cover requirement for watermains here in south-western Ontario, since we are comparing bury depths.
2) If you normally need 1.2m cover for frost penetration, then that is what you should have between the outside of your culvert and the sewer and watermain. That said, you can always look...
