Santa Rosa, TX Noise Levels
Santa Rosa, TX: what the federal noise map shows
Santa Rosa, TX's 60-69.9 dB(A) band spans one of HUD's zone boundaries, so the honest answer is a range: somewhere between "Acceptable" (65 dB(A) or below) and "Normally Unacceptable" (65-75 dB(A)), not one clean verdict. Road traffic drives that number here, not the other two sources. Treat this as Santa Rosa's one representative point, not a promise about every block in it, BTS's map wasn't built to resolve individual streets.
Santa Rosa's noise, by source
Each of the three transportation modes gets its own model from BTS; the combined figure above is what they add up to.
What this means for a house here
Depending on where in that band the true value sits, it may also clear FHWA's 66 dB(A) residential impact threshold (23 CFR 772, Table 1), the trigger highway agencies use for sound-wall decisions. Upgraded windows, door seals and STC-rated glazing meaningfully cut broadband, near-continuous road noise.
