Does a NADR have to follow the format of the example on the HQ Environmental website?
A. No – the example shown is a best practices format only. The NADR does need to include all the engineering considerations that result in the noise abatement decision for the project. This includes the acoustic design information from the noise study such as impacted residences, benefited residences, all proposed walls whether reasonable/feasible or not (see Protocol for further discussion), engineer’s estimate for all walls and any other reasonability considerations such as local government interests or competing resources like a scenic view. The NADR documents which walls are proposed to be a part of the project subject to public review in the draft environmental circulation.
