Is there a 3.5e book detailing Baldur’s Gate circa 1380?

I am playing in a game set in Baldur’s Gate in year 1380 and I’m trying to understand the geography of the city and its districts at that time (1372 is also good).

Which books have a map or a description of the districts of the town in that era?

I can only find D&D 2e material (Volo’s Guide to the Sword Coast) and D&D 5e material (Murder in Baldur’s Gate and Baldur’s Gate: Descent into Avernus), both named in this question.

I am mostly interested in finding out when the lower city stopped being called Heapside as a whole giving birth to Bloomridge and other districts and when was Twin Song founded, but should the 3.5e material not talk about these things I will ask new questions (or ask Ed Greenwood).
