MEMORANDUM
TO: Jim Grube, Hennepin County Scott Pedersen, MnDOT FROM: Graham Johnson, PE Samuel Turrentine, AICP DATE: July 27, 2016 RE: Final Noise Memorandum SEH No. HENNC 113114 14.00 Traffic Noise Analysis Summary The I-35W and Lake Street Improvement Project would result in changes in future (year 2038) traffic noise levels compared to existing (year 2018) traffic noise levels. Under the future Build (2038) alternative, daytime traffic noise levels range from 49.7/47.6 dBA (L10/L50) to 79.2/75.0 dBA (L10/L50). Nighttime traffic noise levels range from 49.2/47.0 dBA (L10/L50) to 79.5/75.2 dBA (L10/L50) with future (2038) Build conditions. Modeled noise levels (daytime and nighttime) vary ‐5.2 dBA to 6.6 dBA from existing (2012) conditions. Modeled traffic noise levels exceed the MPCA daytime L10 standard at 715 of 1,455 receptors and the daytime L50 standard at 1,067 of 1,455 receptors. Modeled traffic noise levels exceed the MPCA nighttime L10 standard at 1,279 of 1,455 receptors and the nighttime L50 standard at 1275 of 1,455 receptors. Modeled traffic noise levels exceed the FHWA criteria at 283 of 1,455 receptors. Consideration of Noise Barriers Noise barriers were analyzed at locations along the I-35W and Lake Street Improvement Project corridor where modeled noise levels are projected to exceed State daytime or nighttime noise standards, approach or exceed Federal noise abatement criteria, or result in a substantial increase in noise levels (i.e., traffic noise level increase ≥ 5 dBA from existing levels to future levels under the Build Alternative). Noise barrier construction decisions are based on a study of feasibility and reasonableness. Noise barrier feasibility and reasonableness are described below. Noise Barrier Feasibility Noise barrier feasibility is determined based on a consideration of two factors: 1) acoustic feasibility and 2) engineering feasibility.
• Acoustic feasibility: For a noise barrier to be considered acoustically effective, it must achieve a noise reduction of at least 5 dBA at the impacted receptors for those receptors to be considered benefited by a noise barrier. Not every impacted receptor must receive this minimum 5 dBA reduction; however, at least one impacted receptor must meet the minimum 5 dBA reduction for a noise barrier to achieve acoustic feasibility.
• Engineering feasibility: Engineering feasibility addresses whether or not it is possible to design and construct a proposed noise abatement measure. A sample of potential constructability

considerations include safety, topography, drainage, utilities, and maintenance considerations. Engineering considerations are also taken into consideration in determining noise barrier height. MnDOT has established a maximum noise barrier height of 20 feet above the finished ground line at the noise barrier. In addition, MnDOT has established a maximum noise barrier height of 10 feet above the bridge deck when it is necessary for a noise barrier to be attached to a bridge structure.
Noise Barrier Reasonableness Noise barrier reasonableness decisions are based on a consideration of three reasonableness factors: 1) noise reduction design goal, 2) cost-effectiveness, and 3) the viewpoint of benefited residents and property owners.
• Noise reduction design goal: A minimum 7 dBA reduction must be achieved for at least one benefited receptor behind the noise barrier to meet the noise reduction design goal.
• Cost-effectiveness: To be considered cost-effective, the cost per individual benefited receptor (i.e., residence, commercial entity, industrial entity) should be equal to, or less than $43,500. In order to assess cost effectiveness, at least one benefited receptor behind the noise barrier must meet the noise reduction design goal described above. The following formula can be used to determine the cost-effectiveness of the barrier:
The cost-effectiveness index is equal to the cost of the noise barrier1 divided by the number of individual benefited receptors (i.e., residences, commercial entities, industrial entities) that are predicted to experience noise level reductions of 5 dBA or more. Only those receptors that experience a 5 dBA or greater decibel decrease are considered in this formula. The result is a cost per benefited receptor value (residence, commercial entity, or industrial entity represented by each modeled receptor). To be considered cost-effective, the cost per individual benefited receptor must be equal to or less than $43,500 per receptor. 1 The cost of a noise barrier is calculated using $20 per square foot of barrier, based on historical data over the five-year period from 2005-2010.
There are several steps to assessing the cost-effectiveness of noise barriers. First, the cost-effective noise barrier height is determined for each segment of the project area, beginning with the evaluation of a 20-foot tall noise barrier (MnDOT maximum height; see discussion of engineering feasibility above). If a 20-foot tall noise barrier achieves the noise reduction design goal, meets the cost-effectiveness criteria and is feasible, it would be proposed for construction. If the 20-foot tall barrier does not meet the noise reduction design goal or cost-effectiveness criteria, then noise barrier heights less than 20 feet are studied. If a noise barrier height less than 20 feet achieves the noise reduction design goal, meets the cost-effectiveness criteria and is feasible, it would then be proposed for construction.
• Viewpoint of Benefited Residents and Owners. The third criterion in determining noise barrier reasonableness is the viewpoint of benefited residents and property owners. A benefited property is defined as a receptor adjacent to a proposed noise abatement measure that receives a noise reduction equal to or greater than 5 dBA. If benefited residents and property owners indicate that a proposed noise barrier is not desired, then the noise barrier is removed from further consideration and would not be constructed with the project.
There are two steps in determining the desires of the benefited property owners and residents regarding the construction of proposed noise abatement measures. First, the viewpoint of benefited property owners and residents is solicited through a public involvement process, such
Final Noise Memorandum July 27, 2016 Page 3
as open house meetings, a project website, and direct mailing of a solicitation form. Second, the input received from benefited property owners and residents through this public involvement process is expressed in a vote that is weighted as follows:
The owner of a benefited property immediately adjacent to the highway right-of-way for the proposed project (i.e., first-row properties) receives 4 points and the resident (owner or renter) receives 2 points. The owner/resident of a benefited property receives a total of all 6 points. The owner of a benefited property not immediately adjacent to the highway right-of-way for the proposed project (e.g. second-row properties, third-row properties) receives 2 points and the resident (owner or renter) receives 1 point. The owner/resident of a benefited property receives a total of all 3 points. When there is no outdoor area of frequent human use associated with a benefited property, the owner of the benefited property receives a total of 4 points if the property is located immediately adjacent to the highway right-of-way (i.e., first-row properties). If the property is not immediately adjacent to the highway right-of-way (i.e. second-row properties, third-row properties), the owner of the benefited property receives a total of 2 points.
Only those benefited property owners and residents, including individual units of multi-family residential buildings that are considered to be benefited receptors, regardless of floor location (e.g., first floor, second floor, etc.), have a vote according to the point system described above. Non-benefiting receptors do not receive points. A simple majority (greater than 50 percent) of all possible voting points for each of the proposed noise barriers must vote “down” the proposed abatement measure in order for it to be removed from further consideration. Noise Barrier Cost Effectiveness Results Seven noise barriers were determined to be feasible based on preliminary design studies, meet MnDOT’s design reduction goal of at least 7 dBA at one benefited receptor behind each noise barrier; and meet MnDOT’s cost-effectiveness criteria of $43,500/benefited receptor. Noise barrier cost-effectiveness results are described in detail in the traffic noise analysis report in Appendix G of the EA/EAW. The locations of the seven proposed noise barriers are identified below.
• Barrier eG: east side of I-35W between the 31st Street Exit Ramp and the 31st Street Bridge (includes 10-foot high noise barrier on the 31st Street Bridge structure)
• Barrier eI: east side of I-35W between the Lake Street Bridge and the Midtown Greenway Bridge (includes 10-foot high barrier on the Midtown Greenway Bridge structure)
• Barrier wB: west side of I-35W between the 36th Street Bridge and the 38th Street Bridge • Barrier sE: south side of I-94 between the 1st Avenue Bridge and the 3rd Avenue Bridge • Barrier sJ: south side of I-94 between the Chicago Avenue Bridge and the 11th Avenue Bridge • Barrier nD: north side of I-94 between the 1st Avenue Bridge and the Nicollet Avenue Bridge • Barrier nJ: north side of I-94 between the 11th Avenue Bridge and the Chicago Avenue Bridge
Solicitation Results (Benefited Property Owners and Residents) Solicitation forms were mailed on January 29, 2015, to the benefited property owners and residents adjacent to the seven proposed noise barriers. The invitations included a banner in Spanish, Hmong, and Somali explaining whom to contact for translation assistance, or for general help in understanding the
Final Noise Memorandum July 27, 2016 Page 4 noise barrier impacts. A total of 94 solicitation forms were mailed to benefited property owners and residents. Two identical public hearing/open house meetings for the proposed project were held on April 5, 2016 and April 19, 2016 at the Colin Powell Center, 2924 4th Avenue South, Minneapolis, MN 55408. Separate noise wall meetings were also held before the publication of the EA/EAW. A general information meeting, which included both voting and non-voting parties, was held for each proposed noise wall location in February and March, 2015. Each meeting included an overview of the MnDOT noise policy and an explanation of how the noise wall voting process would occur. Preliminary design information and visualization materials on the proposed noise barriers were also presented. Another round of meetings occurred in March and May, 2015 for those eligible to vote on a specific noise wall (benefitted receptors). The noise solicitation process meeting dates/locations are summarized in Table 1. Solicitation forms and comments regarding the proposed noise barriers were received through Wednesday, April 27, 2016.

Conclusions and Recommendations Proposed Noise Barriers Based on the traffic noise studies completed to date, MnDOT intends to construct a highway traffic noise abatement measure in the form of an approximately 20-foot high barrier at one location along the project corridor. The noise barrier is feasible, meets MnDOT’s design reduction goal of at least 7 dBA and cost-effectiveness criteria of $43,500/benefited receptor, and is supported by adjacent benefited receptors.
• Barrier eI (east side of I-35W between the Lake Street Bridge and the Midtown Greenway Bridge, with a 10-foot high barrier on the Midtown Greenway Bridge structure). This proposed barrier is approximately 590 feet long, and runs from the Lake Street Bridge to the Midtown Greenway Bridge and includes a 10-foot high barrier on the Midtown Greenway Bridge structure.
Not Proposed Noise Barriers
• Barrier eG (east side of I-35W between the 31st Street Exit Ramp and the 31st Street Bridge, with a 10-foot high noise barrier on the 31st Street Bridge structure). An approximately 20-foot high, 719-foot long noise barrier (total length includes a 100-foot long, 10-foot high noise barrier on the 31st Street Bridge structure) is feasible, meets MnDOT’s noise reduction design goal of at least 7 dBA at one or more benefited receptor, and meets MnDOT’s cost-effectiveness criteria of $43,500/benefited receptor. A solicitation form was distributed to all benefited property owners and residents adjacent to this barrier to solicit their viewpoint, and voting points were tabulated. A majority (67%) of the total possible points responded “no” to this noise barrier. Therefore, Barrier eG will be eliminated from this project.

Statement of Likelihood The preliminary indications of likely abatement measures described above are based upon preliminary design. Final mitigation decisions will be subject to final design considerations. If it subsequently develops during final design that conditions have substantially changed, noise abatement measures may not be provided. Decisions to eliminate or substantially modify a noise abatement measure must be approved by MnDOT and the FHWA Minnesota Division Office. Affected benefited receptors and local officials will be notified of plans to eliminate or substantially modify a noise abatement measure prior to the completion of the final design process. This notification will explain changes in site conditions (if any), additional site information, any design changes implemented during the final design process, and an explanation of noise barrier feasibility and reasonableness. sbt
