This is the model that you are seeking:
You create the table view of the raster, sort that into an in-memory table, then use the Get field value which only every looks at the first row which is your sorted data by count and then the extract by attribute is an SQL clause Count = %MAX_Value%.

This is the workflow I'd recommend:
Add a definition query to your pipes for your branch pipe (Trunk =
'No')
Buffer pipes with a small distance (1 foot), dissolve type ALL
Split your buffers using Multipart to Singlepart
Add a unique ID value to each singlepart buffer
Spatially Join buffer unique ID to your pipe features
Spatially join pipe unique ID to ...

The single equals sign (=) is used for assigning a value, not testing for equality. To test for equality, use the double equals sign (==).
So instead of:
if int([Most_Recen]) = 0:
it should be:
if int([Most_Recen]) == 0:
Although, since zero (0) evaluates to false, you could skip the equality test altogether, and just check the "truthiness" of the ...

It sounds like you are trying to use the Water Geometric Network Editing and Analysis solution which is part of ArcGIS Solutions for Water:
Water Geometric Network Editing and Analysis requires specific technical experience and software
including
ArcMap (Standard or Advanced) 10.2.1, 10.4 - 10.7
Consequently, it appears that your ArcGIS Desktop ...

I am not sure I understood your question, I will explain about ArcGIS 9.3 because you tagged ArcGIS 10.0. Thus, I am not sure are you talking about version 10 or need older than 10 like 9.3.
You can clear selection from Options as you already knew or from Selection Menu -> Clear selection
Using ArcGIS 9.3 and under the section Selecting features by ...

The Clip tool should work, but I too have seen it not work correctly, even with the use of FeatureLayers. If Clip isn't behaving, my process is the following:
Get the clipping geometry and cast as ITopologicalOperator
Loop through the features will be clipped
Use ITopological.Intersect to get the clipped geometry (Use intersect)
If the returned geometry is ...

If you're already calling GP tools within your code, the easiest way to accomplish what your asking is to pass the result of the Select Layer By Attribute GP tool (or other selection tool) to the Clip GP tool. You will need to convert the "suburban" feature class to a feature layer first. The simple steps would be:
Convert suburban feature class to feature ...

I do not think this is possible in ModelBuilder.
But you could create a model that :
convert the line vertex to point
add XY (and if needed ZM) coordinate to the newly created point
select some of the point
Export a table with the coordinate you're after

Below is 2D solution to replace cross-sections approach I suggested in comments. Picture shows routes as lines:
Place multiple points on them to represent width of corridor, by using linear referencing for example:
Use kernel density (EXPECTED_COUNTS) on above points with population
field NONE, call output COUNT.
Use kernel density (EXPECTED_COUNTS) on ...

Convert your raster to points using the Raster to Point tool in ArcToolbox-Conversion Tools-From Raster - Raster to Point. This tool may result in a fairly large feature class depending on how many pixels your image has. After conversion you might use the add geometry tools to populate the attribute table with coordinate values if you needed to.

Try sending your token in the URL query params (string path = @"https://services3.arcgis.com/{My ID}/ArcGIS/rest/services/{Service Name}/FeatureServer/0/query?where=FID>0&outFields=*&token=______";) instead of in the headers.

Assuming that each road segment that you want to buffer is available as a line feature you could use the Buffer tool and specify the buffer size using a buffer field:
The distance around the input features that will be buffered.
Distances can be provided as either a value representing a linear
distance or as a field from the input features that ...

If your destination is an ESRI geodatabase (enterprise geodatabase or file geodatabase).
Use the "Feature Class to Feature Class" tool, or the "Copy Features" tool.
For more information (including the difference between the two tools) see: Difference between Copy Features and Feature Class to Feature Class tools?
OR, if you only want the attributes, and ...

First little issue I see is that your second arcpy.ListTables is not capitalized right (you have arcpy.listTables). Python is case-sensitive, so this is important.
Secondly, arcpy.ListTables only searches in the current workspace. So before you search for the files, you need to tell it where to look by adjusting the workspace variable to the location where ...

Try "*level*" and "*_Merge" for your wildcard parameter values.
Alternatively, don't include a wildcard at all, but use an if, something like:
for theTable in arcpy.ListTables():
if theTable[-6:-1] == "level" or theTable[-6:] == "_Merge":
print "Deleting: {}".format(theTable)
arcpy.Delete_management(theTable)
I would comment out that ...

As I understand it GCS_Airy_1830 is the datum for the projected coordinate system OSBG_1936_British_National_Grid. So they are not different coordinate systems. A datum is a component of a coordinate system. As you are working on data in the UK ensure your datasets are projected into the British National Grid, this will make subsequently mapping and analysis ...

Not sure if it's still actual but:
Have you ever had you locator working with the original "50000 lines of magic Xml" file?
If Yes and you just need to clean up the file to 400-600 lines, I'd suggest to delete them by small pieces and rebuild the locator after each update. In order to catch the part that you mistakenly deleted.

You can download the .style file at this Git repo: https://github.com/ISUEOGTP/GISTaskSheet mentioned in these PDF instructions: https://indicator.extension.iastate.edu/projects/tasksheets/reports/PM2082-14e.pdf
These instructions also explain how to import it once you have it.

The quickest way to estimate errors is to set up some sample points (say five, more is better) with exact coordinates, and perform round trip calculations.
Datum A -> transformation X -> Datum B -> transformation Y -> Datum A
Then you directly can compare coordinates before and after.
Alternatively: WGS84 -> transformation X -> Datum A ; WGS84 -> ...

If anyone wants to do this with r, I found a script written by Barry Rowlingson on R-sig-geo that still works fairly well.
Two functions: one computes evenly spaced points along a set of xy coordinates, the other works out the end point of transects centered on those points:
# How to generate perpendicular transects along a line feature
evenspace <- ...

All the links from the previous answers did not work anymore (at least for me) as of Nov 2019. The ColorBrewer.style file for ArcGIS 10.xxx can be downloaded from here.
Copy the .style file to C:\Program Files (x86)\ArcGIS\Desktop10.6\Styles (for ArcGIS 10.6). Then add any shapefile to a blank ArcMap document.
Double click on the layer, go to Symbology ...
