Q2. normal cost per receptor calculations are not valid. Cost, severity of impact, type of use (interior/exterior), time of use (compared to worst case hour), complaints received and public involvement are crucial.
*Q9. Criteria Methodology
Mass. Highway Dept.
MHD has rejected requests for noise abatement for special land uses on all Type I projects. Reason being that they can't justify spending the money on park, playground, cemetery, church when there are residential areas that have been deemed marginally feasible for a barrier. There is no criteria to allow for equal consideration of special land use case versus residential areas.
The only time abatement is offered to special land use area is when it is surrounded by a residential area that has been deemed reasonable/feasible for a barrier.
MHD has attempted to consider special land use cases with study (MHD Type II Noise Attenuation Study). Although there is still reluctance to build barrier for location if there are marginal residential areas also on the list.
MHD relies heavily on cost/dBIL/residence protected
Notes:
Special Land Use Priority Primary Rating System
Primary rating system is the sum of all such points for all noise-sensitive activities n the barrier study zone.

Criteria/Reasonableness for special land use:
Date of development must be earlier than the highway
Fixed developed sites of frequent human use within 300m of ROW, this excludes dispersed recreation sites(fishing, Xcountry skiing areas), including their parking facilities, also excluded are roadside facilities, rest areas....
Centers of human activity must be impacted by highway noise
Time of use may be a factor, churches used only for Sunday worship do not qualify since the peak traffic hours do not coincide with "frequent human use: criteria."
Activity Type: for schools, these are divided into indoor and outdoor activities. Many times the outdoor areas are shielded by the building. The school building indoor is examined for noise penetrating the building if the outdoor NAC is exceeded during time of use.
Building material is a factor only if the outdoor NAC is exceeded during time of use. If a school has solid brick or masonry block structure facing the highway, no further shielding is needed. Or if the widows are double or triple glazed or glass block and the walls are brick or masonry block, no further shielding is needed.
Noise abatement must comply with the usual criteria for dwellings(5 dB(A) reduction, cost not exceeding limit per dwelling.
Can place imaginary dwellings if there is a site without dwellings to see if the cost is reasonable.
COST PER DWELLING FORMULA:
Cost= C/SD
C = Total cost of abatement
D = number of impacted dwellings that receive 3dB reduction within 300m of ROW
S = severity factor (Type II S=l)
Type I | ||||
---|---|---|---|---|
NAC exceeded | Increase in level | |||
0-9 | 10-19 | 20-29 | 30+ | |
Yes | 1 | 2 | 3 | 4 |
No | - | 1 | 2 | 3 |
Cost: how bad do you want the project approved by the Feds? 30k/dwelling is normally used
Facility type/Time of use: Churches are normally dismissed because of time of use. Every opportunity is used to show it is not an impact because of the time of use issue. Other than impact vs. no impact, cost is the only issue when determining reasonable/feasible in Wis.
Wyoming DOT
Reasonableness (Residences)
Amount of noise reduction provided (7dB A or greater)
all benefited receivers should be included in the analysis regardless £>r whether they were identified as impacted(each unit in a multi-family building should be counted as one residence)
Cost: $ 15 k/resident or less
Opinion of impacted residents: surveys or open house to determine
Future noise levels: >70 dB(A) or 20 dB(A) increase
Timing: Consider those residences that existed before the project or along a highway for an extended period of time
Notes:
55 dB(A) is the threshold of concern, above this consider mitigation (Leq24)
65 dB(A) is interpreted as twice as noisy and speech/sleep interference expected
Mitigation warranted if levels 10 years after project:
Must be able to achieve at least 5 dB(A) reduction
Schools abate: L10 worst hour >50 dB(A) inside or 60-70 dB(A) outside, 5 dB reduction must be achieved
Rural areas: alignment efforts should be made if levels are below 55 dB(A) but have increased by 10 dB over pre-project levels
Cost: $15k/directly facing residential unit
Land use/Facility Type: The type of land use with its standardized max noise level determines the necessary decrease of noise level depending on the surroundings.
cost: will limit the possible solutions but should not prevent the most effective solution.
Important items
build versus no-build noise levels
number of exposed persons
cost
