Hello! I'm glad that you are making something that resembles your home town, but don't let that whole idea and layout block game play. There are some changes that need to be made to the current layout and here's why:
The timings are way to long. Just by doing my own little run through, I was able to scrap together timings at about 15-20 seconds for Ts to get to either bombsite. These timings need to be shaved down to anywhere between 8-15 seconds. Or you could make one site a rush site and one site a slower methodical site.
Footstep differentiation is a key Counter-Strike feature. (Mentioned previously by @Simpajo) A lot of players will say that Nuke is their least favorite map because they can't hear where anything is coming from. They can't tell where footsteps are and you their echolocation skills to determine where the enemy team is. If you want to keep the bombsites where they currently are, maybe consider making the two bombsites have different floor types so that the footstep sounds are different.
There is a lot of unused/useless space. Just by running around, I can tell that if this map was played, about 90 percent of it wouldn't be used by anybody except a lurker/flanker. The main focus around the map would be around the church square. The whole top lane of the map is usually not going to be touched by teams unless they are flanking because they wouldn't want to put themselves at a distinct disadvantage by taking a longer route. CTs would only have to put one player there for information and if they know they are taking that route, they can easily collapse and trap the Ts.
Overall, the map layout needs a rework. This is why play testing early is always good because it can help you work out the kinks of a layout. I see that you've put a lot of time and effort into this map and I would hate to see it go to waste. I think the easiest way to salvage this map would be to move the back bombsite (I believe A site) towards the tent area of the map. I would then shorten some of the corridors up to help fix some timings, and that should solve a lot of the problems with the layout at this point in time I believe. I really believe that you have a good theme to your map and I hope that you can change the layout even if it isn't true to the references anymore.
I hope you found my advice and criticism constructive! I'm not trying to be mean or anything, I'm just trying to help you make your map the best that it can be! If you have any questions at all I would be happy to answer them either here or in a direct message.
Thanks!
