Thanks to everyone for the information… very helpful and appreciated.
I have enclosed a Google Map link to the location of the parking space that you can view on Street View.

The parking space where my vehicle was damaged is where the dark blue/navy SUV is parked, (near the light pole).
I'm glad it was resolved to your satisfaction.
Okay, so a full size SUV can park in the space, with several feet of space behind them and the cable clearly runs from the ground at the front of the space. I see why no observant driver should miss it.
(you get a perfect view of the anchor and cable by looking from the other side of the SUV)
With this being diagonal parking, is it possible to hit the wire without the passenger side of your vehicle passing at least several inches over the edge of the curb? I think it's an odd placement for a support cable, I can see how it could be difficult to spot the cable in certain light conditions, and I can see why it would normally be marked with some sort of reflective coating, but if you would only hit the stake or cable after pulling past the curb I would not be surprised if the municipality asserts (in addition to any claim that you should have seen the stake and cable) that you can't hit the post unless you park improperly.
I guess for now, you wait to see how the municipality responds. As the post at issue is a light post, it would seem to be a post for which the municipality is responsible as opposed to a utility company.
If you navigate further on the street, using google street view, and then rotate you can see the spike. It is not in the concrete, but in the blacktop that is part of the parking space. You would hit it before you ever reached the concrete sidewalk. I think the OP has a legitimate claim here.
I did look at it. The stake appears to be on the driver's side of the space, about four or five inches from the curb, and about 40% of the way across the space from driver's side to passenger side. Judging from the angle of the parking, based upon Google's photographic and satellite images, it does not appear that the front of a vehicle could touch the stake or cable unless the passenger side of the vehicle extended over the edge of the curb:
If the images are misleading, I suggest that you take some photographs of your own to document that you can hit the stake without any portion of your car extending over the curb and using them in support of your claim, as it could become an issue.
The vehicle parked in the space in the image currently is a large vehicle, a Ford Explorer, which sits high off the ground and it is parked closer to the right (passenger) stripe than the left. If you imagine a Chevy Spark or perhaps a Fiat 500 parked closer to the left stripe, but still within the space, I think it might be easier to envision a vehicle striking these obstacles without hanging over the sidewalk. Any vehicle that sits lower to the ground would to that, actually. Imagine a fiberglass Corvette parking on the left side of the space, for example. In my own vehicle, an Audi, I can't imagine pulling forward past the sidewalk without hitting that stake, actually...
Also, I don't see where Fla. 316.1945 prohibits any portion of a vehicle extending over a sidewalk. It only prohibits parking "on" a sidewalk. Without cement stops, I suspect the city is aware that vehicles extend over the sidewalk in this area on a regular basis. From various angles it is clear that many of the vehicles present during this Google street view pass extend over the sidewalk.
