Noise – Florida's Turnpike.

Example noise analysis from just south of us at Groveland.

It seems reasonable to expect a wall. Note excerpt “ In some cases, it is because the cost per benefited residence exceeds the FHWA and FDOT threshold. If the cost of the noise wall is greater than the cost per benefited residence, currently $42,000 per benefited residence, the wall is not considered reasonable. Dense neighborhoods have a greater chance of being cost effective than neighborhoods with large tracts of land for each house.”

The neighborhood should be considered dense enough population wise. We know these projects have cost caps, but a noise wall wouldn’t be a reason to have to push additional appropriations through the Florida government. Fortunately the neighborhood would be preexisting from 460 to 44.
